FS608R Digital Camera Binoculars FHD 1080P: Review

The FS608R Digital Camera Binoculars FHD 1080P from Gear Best is a low-end binocular with a built in camera that takes up to 2592 x 1944 (defaults to 2,048 x 1,536, and can go lower) pixel photos or avi movies (no sound).

Really good binoculars cost hundreds of dollars, but there is a range of inexpensive binoculars that everybody who uses binoculars (especially bird watchers) and/or has kids owns a few of. This is the extra set of binocs you keep in your car, near back yard window, let your kids play around with, or if you are a biology teacher, bring to school for the trip down to the nearby wildlife park on sample collection day. Everybody’s got a few of these, and this particular binocular could easily be one of those.

The FS608R at the discounted price at GearBest of just under $70 is not as good as comparable low end binoculars optically, but the photographs it takes are actually impressive. (The same binoculars are Amazon are $170, elsewhere in the $80s or $90s.) Clearly, you are paying for the electronics. Interestingly, the quality of the photographs is much higher than one might expect when just looking through the binoculars. The movies are not anything special, don’t get it for the movies, but it is a nice feature to have.

As is the case with any binoculars, the focusing is key. If you are used to self-focusing or almost-always-infinity cameras, you will have to learn to respect the focus, but once you get that straight, the photos are amazingly good for the price of the device. The camera uses a micro SD card (not supplied, and if you don’t have one you’ll want to get an SD card adapter so you can get the micro SD card in your card reader). The camera also has a USB connector as an option for getting the shots off the binoculars.

It think this set of binoculars is going to get a lot of use in our family, and in Amanda’s classroom.

I don’t know much about GearBest, but it seems to be a relatively new China-based outlet for medium to low range (in price) electronics. The normal price for the FS608DR digital camera binocs is 180.00, which is more than you should pay for this device, but the discounted price is reasonable.

Tales of the Ex-Apes

Jonathan Marks’ new book is called “Tales of the Ex-Apes: How We Think about Human Evolution

I’ve got to tell you that when I first saw the title of this book, the letters played in my head a bit. Tails of the Ex-Apes. That would be funny because apes don’t have tails. Or Tales of the Exapes. Pronounced as you wish. Perhaps in an Aztec accent.

Anyway…

Staley_2009_author_lJon Marks is a colleague and a friend from way back. He is a biological anthropologist who has engaged in critical study of central biological themes, such as genetics, and he’s said a few things about race. He wears black, often does not shave, and has probably been a member of the Communist Party, or at least, taught a class or two on Marxist Theory. So, a book by Marks on “how we think about human evolution” (the subtitle) is not going to be about human evolution, but how we frame questions about human evolution, and how the process of unraveling answers to these questions revel our own biases. Dialectical stuff. Like that.

In the book Jon says interesting things about basic anthropological theory, thought, and key touchstone figures and topics like Darwin and kinship. On the more biological side of things, species, adaptations, gene trees, and phylogeny. The destructive core of the book is an anti-reductionist critique of evolutionary theory and the constructive core of the book is an bio-cultural argument as it applies to doing anthropology, as well as how it applies to the human (or just prehuman?) transformation to a self considering sort of sentient being that bothers to write books about the process of asking questions about itself. Humans are a product of lived experience, but not just that. Humanness is the product of the sum of human’s cultural history. And, actually, science, which is an important human thing, does not escape that framework, something I probably agree with (^^see the subtitle of my blog^^). Marks writes,

… we see the human species culturally. Science is a process of understanding, and we understand things culturally. We hope that we can observe and transcend the cultural biases of our predecessors, but there is no non-cultural knowledge. As a graphic example, consider the plaque that was attached to Pioneer 10 … Why was NASA sending pornography into outer space? … Because they wanted to depict the man and woman in a cultureless, natural state. But surely the shaves, haircuts, and bikini waxes are cultural! As are the gendered postures, with only the man looking you straight in the eye. In a baboon, that would be a threat display; let’s hope the aliens … aren’t like baboons.

And so on. Like that. Great book.

If you are teaching a course in human evolution, you might seriously consider using this as a second reading because of the critical treatment of material surely left unexamined by your textbook. Also, it would give the students a fairer sense of what they are in for if they chose Anthropology as a major, for better or worse. This is not introductory material, but the prose would work for any college student. Also, the text is well footnoted.

The book will be out any day now, scheduled for September. Available in various formats, very much worth the read.

The outlook for Hawaiian coral is bleak

Marine biologists from the University of Queensland is looking at coral reefs in Hawaii and what they see is not good.

They used high resolution images to track coral bleaching and death. Recently coral reefs in Hawaii suffered their first known mass bleaching event, caused by unusually warm waters associated with the now famous “Blob” of warm sea water in the Pacific.

An overall warming trend (anthropogenic global warming) along with the additional effects of a growing El Niño seem to be causing this.

This phenomenon is happening now. Ove Hoegh-Guldberg, chief scientist at Global Change Institute (Queensland) noted. “the coral bleaching we are uncovering in Hawaii is just the tip of the iceberg in terms of what we expect to unfold over the next few weeks. Ocean heat has not fully dissipated since last year’s bleaching event, adding stress to corals that haven’t fully recovered and which may not be strong enough to survive another bleaching event.”

The research team will continue to measure bleaching on the Hawaiian reefs for the remainder of the year. With increasingly warm waters in the region, this is a story to watch closely.

Climate Change Plus Irreversible Evolution Will Force Key Ocean Bacteria into Overdrive

I’ve got a press release from the University of Southern California that seems important, but I don’t have time today to read the study. So, you can look at the press release and tell me what you think of it.

Climate Change Will Irreversibly Force Key Ocean Bacteria into Overdrive

Scientists demonstrate that a key organism in the ocean’s foodweb will start reproducing at high speed as carbon dioxide levels rise, with no way to stop when nutrients become scarce

Imagine being in a car with the gas pedal stuck to the floor, heading toward a cliff’s edge. Metaphorically speaking, that’s what climate change will do to the key group of ocean bacteria known as Trichodesmium, scientists have discovered.

Trichodesmium (called “Tricho” for short by researchers) is one of the few organisms in the ocean that can “fix” atmospheric nitrogen gas, making it available to other organisms. It is crucial because all life — from algae to whales — needs nitrogen to grow.

A new study from USC and the Massachusetts-based Woods Hole Oceanographic Institution (WHOI) shows that changing conditions due to climate change could send Tricho into overdrive with no way to stop — reproducing faster and generating lots more nitrogen. Without the ability to slow down, however, Tricho has the potential to gobble up all its available resources, which could trigger die-offs of the microorganism and the higher organisms that depend on it.

By breeding hundreds of generations of the bacteria over the course of nearly five years in high-carbon dioxide ocean conditions predicted for the year 2100, researchers found that increased ocean acidification evolved Tricho to work harder, producing 50 percent more nitrogen, and grow faster.

The problem is that these amped-up bacteria can’t turn it off even when they are placed in conditions with less carbon dioxide. Further, the adaptation can’t be reversed over time — something not seen before by evolutionary biologists, and worrisome to marine biologists, according to David Hutchins, lead author of the study.

“Losing the ability to regulate your growth rate is not a healthy thing,” said Hutchins, professor at the USC Dornsife College of Letters, Arts and Sciences. “The last thing you want is to be stuck with these high growth rates when there aren’t enough nutrients to go around. It’s a losing strategy in the struggle to survive.”

Tricho needs phosphorous and iron, which also exist in the ocean in limited supply. With no way to regulate its growth, the turbo-boosted Tricho could burn through all of its available nutrients too quickly and abruptly die off, which would be catastrophic for all other life forms in the ocean that need the nitrogen it would have produced to survive.

Some models predict that increasing ocean acidification will exacerbate the problem of nutrient scarcity by increasing stratification of the ocean — locking key nutrients away from the organisms that need them to survive.

Hutchins is collaborating with Eric Webb of USC Dornsife and Mak Saito of WHOI to gain a better understanding of what the future ocean will look like, as it continues to be shaped by climate change. They were shocked by the discovery of an evolutionary change that appears to be permanent — something Hutchins described as “unprecedented.”

“Tricho has been studied for ages. Nobody expected that it could do something so bizarre,” he said. “The evolutionary biologists are interested in it just to study this as a basic evolutionary principle.”

The team is now studying the DNA of Tricho to try to find out how and why the irreversible evolution occurs. Earlier this year, research led by Webb found that Tricho’s DNA inexplicably contains elements that are usually only seen in higher life forms.

“Our results in this and the aforementioned study are truly surprising. Furthermore, they are giving us an improved, view of how global climate change will impact Trichodesmium and the vital supplies of new nitrogen it provides to the rest of the marine food web in the future.” Webb said.

The research appears in Nature Communications on September 1. It can be found online at: http://www.nature.com/ncomms/2015/150901/ncomms9155/full/ncomms9155.html

The abstract of the study is here:

Nitrogen fixation rates of the globally distributed, biogeochemically important marine cyanobacterium Trichodesmium increase under high carbon dioxide (CO2) levels in short-term studies due to physiological plasticity. However, its long-term adaptive responses to ongoing anthropogenic CO2 increases are unknown. Here we show that experimental evolution under extended selection at projected future elevated CO2 levels results in irreversible, large increases in nitrogen fixation and growth rates, even after being moved back to lower present day CO2 levels for hundreds of generations. This represents an unprecedented microbial evolutionary response, as reproductive fitness increases acquired in the selection environment are maintained after returning to the ancestral environment. Constitutive rate increases are accompanied by irreversible shifts in diel nitrogen fixation patterns, and increased activity of a potentially regulatory DNA methyltransferase enzyme. High CO2-selected cell lines also exhibit increased phosphorus-limited growth rates, suggesting a potential advantage for this keystone organism in a more nutrient-limited, acidified future ocean.

Slowing global warming would save piles of money

The Citi Global Perspectives and Solutions thingie, part of Citibank, has done a study that you can read here. It says that addressing global warming makes economic sense. So, when those science deniers are out there denying climate change they are also denying arithmetic. Shame on them.

Dana Nuccitelli, author of Climatology versus Pseudoscience and Guardian Blogger, wrote up the report at Skeptical Science:

Citi Global Perspectives & Solutions (GPS), a division within Citibank (America’s third-largest bank), recently published a report looking at the economic costs and benefits of a low-carbon future. The report considered two scenarios: “Inaction,” which involves continuing on a business-as-usual path, and Action scenario which involves transitioning to a low-carbon energy mix.

One of the most interesting findings in the report is that the investment costs for the two scenarios are almost identical. In fact, because of savings due to reduced fuel costs and increased energy efficiency, the Action scenario is actually a bit cheaper than the Inaction scenario.

Go read Dana’s writeup. There are flow charts and a pie diagram!

Tristes Tropiques

Not the book (which is good) but the thing. The storms, really.

I may have mentioned the pilot whales I saw in San Diego the other day. You’ve heard about changes in shark distributions, and odd fish being caught in unusual places, etc. This is all about changes in the Pacific as increased global warming affects ocean ecology. Inside Climate News has this:

A

Warmer North Pacific Is Staying Warmer, With Dramatic Impact on Marine Life
Ocean temperature fluctuations have slowed, a new study says, with an extended warm period in the N. Pacific causing a massive shift in marine life.

One study suggests that there may be a new, but small, hurricane basin in the future: Climate change brings cyclone risk to Persian Gulf: study

See the graphic above. We are experiencing yet another “oh wow” event in the tropics, which seem to be littered with cyclones. Check out the details at the Weather Underground tropical storm section.

We like to go to dry places, they are sunny, don’t smell like mildew, and generally make great destinations. But they are spots, fixed in space, on the landscape, and with climate change they are affected and can’t just get up and move. See: The Coolest Places We’re Losing to the Drought

Jeff Masters talks about Fred. This is the first fully formed hurricane since 1892 to hit the Cape Verde, and is likely the farthest east forming hurricane on record. By the time you read this Fred will be a big wet smear rather than a hurricane, but during its short life it set some interesting records.

Who thinks what about climate change and science?

Two items of interest.

1) A new poll looks at conservative and liberal views of science. The findings are not especially unexpected, but the details are interesting. The image above is from this infographic, and the details are given here.

Yes, the detail are quite interesting.

2) If you care, there is some information on what the 2016 GOP candidates stand on climate change.

This is put together by CBS and is here.

Climate Change Viewed From Alaska

Alaska is being called the poster child (state?) for climate change because things have been so strange there lately. One reason for this is the extreme warm conditions in the North Pacific and associated (probably) changes in the jet stream, as well as overall warming, which has caused coastal Alaska to become a warm place, glaciers to melt, and (in the farther north) sea ice to be less. And now, President Obama has made a trip there and given a big speech.

President Obama’s speech:

More information on the President’s trip here.

Meanwhile, another study cites arctic ice loss as a factor in extreme events.

The new study, published Monday in the journal Nature Geoscience, advances a growing body of science demonstrating that these record-breaking extremes have not been a pause in the advance of human-driven climate change but a result of it.

The newly published study, led by Jong-Seong Kug of South Korea’s Pohang University of Science and Technology, used climate and weather observations as well as climate change modeling to investigate potential connections between these and other extreme cold winter weather systems over North America and South Asia last winter and historically low levels of summer sea ice in areas of the Arctic Ocean.

I’ve written about this quite a bit before. See:

REMARKS BY THE PRESIDENT

AT GLACIER CONFERENCE

Dena’ina Civic and Convention Center

Anchorage, Alaska

5:00 P.M. AKDT

 THE PRESIDENT:  Thank you so much.  Thank you.  (Applause.) It is wonderful to be here in the great state of Alaska.  (Applause.) 

I want to thank Secretary Kerry and members of my administration for your work here today. Thank you to the many Alaskans, Alaska Natives and other indigenous peoples of the Arctic who’ve traveled a long way, in many cases, to share your insights and your experiences. And to all the foreign ministers and delegations who’ve come here from around the world — welcome to the United States, and thank you all for attending this GLACIER Conference.

The actual name of the conference is much longer. It’s a mouthful, but the acronym works because it underscores the incredible changes that are taking place here in the Arctic that impact not just the nations that surround the Arctic, but have an impact for the entire world, as well.

I want to thank the people of Alaska for hosting this conference. I look forward to visiting more of Alaska over the next couple of days. The United States is, of course, an Arctic nation. And even if this isn’t an official gathering of the Arctic Council, the United States is proud to chair the Arctic Council for the next two years. And to all the foreign dignitaries who are here, I want to be very clear — we are eager to work with your nations on the unique opportunities that the Arctic presents and the unique challenges that it faces. We are not going to — any of us — be able to solve these challenges by ourselves. We can only solve them together.

Of course, we’re here today to discuss a challenge that will define the contours of this century more dramatically than any other — and that’s the urgent and growing threat of a changing climate.

Our understanding of climate change advances each day. Human activity is disrupting the climate, in many ways faster than we previously thought. The science is stark. It is sharpening. It proves that this once-distant threat is now very much in the present.

In fact, the Arctic is the leading edge of climate change — our leading indicator of what the entire planet faces. Arctic temperatures are rising about twice as fast as the global average. Over the past 60 years, Alaska has warmed about twice as fast as the rest of the United States. Last year was Alaska’s warmest year on record — just as it was for the rest of the world. And the impacts here are very real.

Thawing permafrost destabilizes the earth on which 100,000 Alaskans live, threatening homes, damaging transportation and energy infrastructure, which could cost billions of dollars to fix.

Warmer, more acidic oceans and rivers, and the migration of entire species, threatens the livelihoods of indigenous peoples, and local economies dependent on fishing and tourism. Reduced sea levels leaves villages unprotected from floods and storm surges. Some are in imminent danger; some will have to relocate entirely. In fact, Alaska has some of the swiftest shoreline erosion rates in the world.

I recall what one Alaska Native told me at the White House a few years ago. He said, “Many of our villages are ready to slide off into the waters of Alaska, and in some cases, there will be absolutely no hope -– we will need to move many villages.”

Alaska’s fire season is now more than a month longer than it was in 1950. At one point this summer, more than 300 wildfires were burning at once. Southeast of here, in our Pacific Northwest, even the rainforest is on fire. More than 5 million acres in Alaska have already been scorched by fire this year — that’s an area about the size of Massachusetts. If you add the fires across Canada and Siberia, we’re talking 300 [30] million acres -– an area about the size of New York.

This is a threat to many communities — but it’s also an immediate and ongoing threat to the men and women who put their lives on the line to protect ours. Less than two weeks ago, three highly trained firefighters lost their lives fighting a fire in Washington State. Another has been in critical condition. We are thankful to each and every firefighter for their heroism — including the Canadian firefighters who’ve helped fight the fires in this state.

But the point is that climate change is no longer some far-off problem. It is happening here. It is happening now. Climate change is already disrupting our agriculture and ecosystems, our water and food supplies, our energy, our infrastructure, human health, human safety — now. Today. And climate change is a trend that affects all trends — economic trends, security trends. Everything will be impacted. And it becomes more dramatic with each passing year.

Already it’s changing the way Alaskans live. And considering the Arctic’s unique role in influencing the global climate, it will accelerate changes to the way that we all live.

Since 1979, the summer sea ice in the Arctic has decreased by more than 40 percent — a decrease that has dramatically accelerated over the past two decades. One new study estimates that Alaska’s glaciers alone lose about 75 gigatons — that’s 75 billion tons — of ice each year.

To put that in perspective, one scientist described a gigaton of ice as a block the size of the National Mall in Washington — from Congress all the way to the Lincoln Memorial, four times as tall as the Washington Monument. Now imagine 75 of those ice blocks. That’s what Alaska’s glaciers alone lose each year. The pace of melting is only getting faster. It’s now twice what it was between 1950 and 2000 — twice as fast as it was just a little over a decade ago. And it’s one of the reasons why sea levels rose by about eight inches over the last century, and why they’re projected to rise another one to four feet this century.

Consider, as well, that many of the fires burning today are actually burning through the permafrost in the Arctic. So this permafrost stores massive amounts of carbon. When the permafrost is no longer permanent, when it thaws or burns, these gases are released into our atmosphere over time, and that could mean that the Arctic may become a new source of emissions that further accelerates global warming.

So if we do nothing, temperatures in Alaska are projected to rise between six and 12 degrees by the end of the century, triggering more melting, more fires, more thawing of the permafrost, a negative feedback loop, a cycle — warming leading to more warming — that we do not want to be a part of.

And the fact is that climate is changing faster than our efforts to address it. That, ladies and gentlemen, must change. We’re not acting fast enough.

I’ve come here today, as the leader of the world’s largest economy and its second largest emitter, to say that the United States recognizes our role in creating this problem, and we embrace our responsibility to help solve it. And I believe we can solve it. That’s the good news. Even if we cannot reverse the damage that we’ve already caused, we have the means — the scientific imagination and technological innovation — to avoid irreparable harm.

We know this because last year, for the first time in our history, the global economy grew and global carbon emissions stayed flat. So we’re making progress; we’re just not making it fast enough.

Here in the United States, we’re trying to do our part. Since I took office six and a half years ago, the United States has made ambitious investments in clean energy, and ambitious reductions in our carbon emissions. We now harness three times as much electricity from wind and 20 times as much from the sun. Alaskans now lead the world in the development of hybrid wind energy systems from remote grids, and it’s expanding its solar and biomass resources.

We’ve invested in energy efficiency in every imaginable way — in our buildings, our cars, our trucks, our homes, even the appliances inside them. We’re saving consumers billions of dollars along the way. Here in Alaska, more than 15,000 homeowners have cut their energy bills by 30 percent on average. That collectively saves Alaskans more than $50 million each year. We’ve helped communities build climate-resilient infrastructure to prepare for the impacts of climate change that we can no longer prevent.

Earlier this month, I announced the first set of nationwide standards to end the limitless dumping of carbon pollution from our power plants. It’s the single most important step America has ever taken on climate change. And over the course of the coming days, I intend to speak more about the particular challenges facing Alaska and the United States as an Arctic power, and I intend to announce new measures to address them.

So we are working hard to do our part to meet this challenge. And in doing so, we’re proving that there doesn’t have to be a conflict between a sound environment and strong economic growth. But we’re not moving fast enough. None of the nations represented here are moving fast enough.

And let’s be honest — there’s always been an argument against taking action. The notion is somehow this will curb our economic growth. And at a time when people are anxious about the economy, that’s an argument oftentimes for inaction. We don’t want our lifestyles disrupted. In countries where there remains significant poverty, including here in the United States, the notion is, can we really afford to prioritize this issue. The irony, of course, is, is that few things will disrupt our lives as profoundly as climate change. Few things can have as negative an impact on our economy as climate change.

On the other hand, technology has now advanced to the point where any economic disruption from transitioning to a cleaner, more efficient economy is shrinking by the day. Clean energy and energy efficiency aren’t just proving cost-effective, but also cost-saving. The unit costs of things like solar are coming down rapidly. But we’re still underinvesting in it.

Many of America’s biggest businesses recognize the opportunities and are seizing them. They’re choosing a new route. And a growing number of American homeowners are choosing to go solar every day. It works. All told, America’s economy has grown more than 60 percent over the last 20 years, but our carbon emissions are roughly back to where they were 20 years ago. So we know how to use less dirty fuel and grow our economy at the same time. But we’re not moving fast enough.

More Americans every day are doing their part, though. Thanks to their efforts, America will reach the emission target that I set six years ago. We’re going to reduce our carbon emissions in the range of 17 percent below 2005 levels by 2020. And that’s why, last year, I set a new target: America is going to reduce our emissions 26 to 28 percent below 2005 levels by 10 years from now.

And that was part of a historic joint announcement we made last year in Beijing. The United States will double the pace at which we cut our emissions, and China committed, for the first time, to limiting its emissions. Because the world’s two largest economies and two largest emitters came together, we’re now seeing other nations stepping up aggressively as well. And I’m determined to make sure American leadership continues to drive international action — because we can’t do this alone. Even America and China together cannot do this alone. Even all the countries represented around here cannot do this alone. We have to do it together.

This year, in Paris, has to be the year that the world finally reaches an agreement to protect the one planet that we’ve got while we still can.

So let me sum up. We know that human activity is changing the climate. That is beyond dispute. Everything else is politics if people are denying the facts of climate change. We can have a legitimate debate about how we are going to address this problem; we cannot deny the science. We also know the devastating consequences if the current trend lines continue. That is not deniable. And we are going to have to do some adaptation, and we are going to have to help communities be resilient, because of these trend lines we are not going to be able to stop on a dime. We’re not going to be able to stop tomorrow.

But if those trend lines continue the way they are, there’s not going to be a nation on this Earth that’s not impacted negatively. People will suffer. Economies will suffer. Entire nations will find themselves under severe, severe problems. More drought; more floods; rising sea levels; greater migration; more refugees; more scarcity; more conflict.

That’s one path we can take. The other path is to embrace the human ingenuity that can do something about it. This is within our power. This is a solvable problem if we start now.

And we’re starting to see that enough consensus is being built internationally and within each of our own body politics that we may have the political will — finally — to get moving.

So the time to heed the critics and the cynics and the deniers is past. The time to plead ignorance is surely past. Those who want to ignore the science, they are increasingly alone. They’re on their own shrinking island. (Applause.)

And let’s remember, even beyond the climate benefits of pursuing cleaner energy sources and more resilient, energy-efficient ways of living, the byproduct of it is, is that we also make our air cleaner and safer for our children to breathe. We’re also making our economies more resilient to energy shocks on global markets. We’re also making our countries less reliant on unstable parts of the world. We are gradually powering a planet on its way to 9 billion humans in a more sustainable way.

These are good things. This is not simply a danger to be avoided; this is an opportunity to be seized. But we have to keep going. We’re making a difference, but we have to keep going. We are not moving fast enough.

If we were to abandon our course of action, if we stop trying to build a clean-energy economy and reduce carbon pollution, if we do nothing to keep the glaciers from melting faster, and oceans from rising faster, and forests from burning faster, and storms from growing stronger, we will condemn our children to a planet beyond their capacity to repair: Submerged countries. Abandoned cities. Fields no longer growing. Indigenous peoples who can’t carry out traditions that stretch back millennia. Entire industries of people who can’t practice their livelihoods. Desperate refugees seeking the sanctuary of nations not their own. Political disruptions that could trigger multiple conflicts around the globe.

That’s not a future of strong economic growth. That is not a future where freedom and human rights are on the move. Any leader willing to take a gamble on a future like that — any

so-called leader who does not take this issue seriously or treats it like a joke — is not fit to lead.

On this issue, of all issues, there is such a thing as being too late. That moment is almost upon us. That’s why we’re here today. That’s what we have to convey to our people — tomorrow, and the next day, and the day after that. And that’s what we have to do when we meet in Paris later this year. It will not be easy. There are hard questions to answer. I am not trying to suggest that there are not going to be difficult transitions that we all have to make. But if we unite our highest aspirations, if we make our best efforts to protect this planet for future generations, we can solve this problem.

And when you leave this conference center, I hope you look around. I hope you have the chance to visit a glacier. Or just look out your airplane window as you depart, and take in the God-given majesty of this place. For those of you flying to other parts of the world, do it again when you’re flying over your home countries. Remind yourself that there will come a time when your grandkids — and mine, if I’m lucky enough to have some — they’ll want to see this. They’ll want to experience it, just as we’ve gotten to do in our own lives. They deserve to live lives free from fear, and want, and peril. And ask yourself, are you doing everything you can to protect it. Are we doing everything we can to make their lives safer, and more secure, and more prosperous?

Let’s prove that we care about them and their long-term futures, not just short-term political expediency.

I had a chance to meet with some Native peoples before I came in here, and they described for me villages that are slipping into the sea, and the changes that are taking place — changing migratory patterns; the changing fauna so that what used to feed the animals that they, in turn, would hunt or fish beginning to vanish. It’s urgent for them today. But that is the future for all of us if we don’t take care.

Your presence here today indicates your recognition of that. But it’s not enough just to have conferences. It’s not enough just to talk the talk. We’ve got to walk the walk. We’ve got work to do, and we’ve got to do it together.

So, thank you. And may God bless all of you, and your countries. And thank you, Alaska, for your wonderful hospitality. Thank you. (Applause.)

September is National Preparedness Month (USGS)

Be prepared!

Did you now that September is, in the US, National Preparedness Month? The idea is to pay attention to natural threats and how to deal with them. This is a project of the USGS. Good idea to give it some thought on this tenth anniversary of Hurricane Katrina.

The USGS recommends a scientific approach, and talks about hurricanes, earthquakes, volcanoes, landslides, sinkholes, geomagnetic storms, drought, floods, wildfire, and more. For information on all of this, including info on The Great Shakout event coming in October (where we all pretend there is an earthquake) click here.

In sum,

Anthropogenic Global Warming Causes Significant Changes in Climate Zones

Human caused climate change is changing the size and location of major climate zones, according to a new study.

Climate is complex, and a classic, widely used effort to wrangle that complexity into a sensible form is the Köppen classification system (and variants). We need not speak of the details here, but within this scheme there are five climate groups that include all of the possibilities for the Earth’s land surface. They are:

  • A: Tropical/megathermal climates
  • B: Dry (arid and semiarid) climates
  • C: Temperate/mesothermal climates
  • D: Continental/microthermal climates
  • E: Polar and alpine climates

This is sort of like a large scale version of the famous planting zone classification you use to determine when to plant your radishes or take in the last of the green tomatoes. The classifications are based on the idea that plants are indicators of the complex mix of factors that determine regional climate. Average temperatures matter, but high and low temperatures, when they occur (during the day and across the march of seasons) matter more, with key values such as frost mattering a lot. Average precipitation matters, but the distribution of precipitation across the year which might result in dry seasons matters a great deal. Ultimately, the local expression of global temperature, moisture, elevation, latitude, and the physical proximity to large bodies of water (most notably the oceans) and mountain ranges result in regional or local climate. The five classifications reflect zones that are mostly distributed across latitude (A on the Equator, E on the Poles) but that are also heavily influenced by altitude.

As humans add greenhouse gasses to the atmosphere the climate changes. We therefore expect these major classifications of regional climate to change as well, both in their relative sizes and in their locations with respect to latitude and altitude.

They do.

A new paper, “Significant anthropogenic-induced changes of climate classes since 1950” by Duo Chan and Qigang Wu, in Nature’s Scientific Reports journal, looks at Köppen classes under global warming, and also attempts to parse out underlying natural variation.

The paper is Open Access so you can go read it yourself. It is very clearly written and interesting. Here, I’ll just give you the key conclusions.

The research uses several data sources to conduct the analysis. All of the data are gridded across the globe, but some grids don’t have their own data because they are in remote areas with little or no instrumentation across the study period. Some data sets interpolate values into these grid squares, and those that do use different methods. One major data set leaves those grid squares blank and treats them as missing data. By using all of the data sets, the researchers were able to avoid coming up with results that were influenced by specific interpolation methods. Most importantly, though, they discovered that using the missing data approach did not change results because the missing data squares are mostly in the most A-like of Group A climate areas or the most E-like of Group E climate areas. Group A climate zones are growing, so being in the middle of those zones does not influence the analysis. So, not knowing what was going on in the middle of the Congo Raiforest does not change anything. Group E climate zones are shrinking, but those areas that are deep wihtin those zones (at the poles, on top of Mount Everest, etc.) don’t matter either.

Group D is “continental” and includes places like Chicago, Seoul, Salt Lake City, Ottawa, Flagstaff, and Faribanks. It is a very large zone that transits places that have real winters and those that have whimpier winters. Even though Group D is huge and significant, it also acts a bit like an ecotone or transition between Group C (Seasonally dry or arid, like Los Angeles, Cape Town, Beirut) and Group E (Tundra, ice caps, etc.). For this reason Group D is divided along the 55th parallel.

There are some complexities in how the data change over time which I will skip here (see the original paper). The point is, the zones do change significantly, with anthropogenic global warming being the primary cause. There is nothing particularly surprising in the results, but details can be important. Most importantly, the study also uses modeling to look at both past and future changes, and predicts an acceleration in change.

This graphic shows changes in climate types over the period 1950 to 2003 using one of the data sets (the data they chose for most of the analysis).

Tropical areas are expanding in space, moving north, and moving up in elevation. Not a lot, but a little. Why not a lot? The study does not say but I’ll guess. The tropical heat and moisture associated with this climate group are rapidly dispersed by air and water circulation systems and become part of the rest of the climate system quickly.

Arid and semi-arid areas (Group B) expand dramatically in area, and also move north and up hill. Why to they expand so much? There are probably two reasons. One is that more heat means more evaporation as well as more holding potential for water in the air. So ground moisture is sucked into the air at a greater rate, and stays there longer. Another (but closely related) reason may be the clumping of moisture we see in certain emerging weather patterns. Clumping means more arid conditions, even if that clumped water all falls eventually, on average, where it might have fallen anyway. A given amount of water falling uniformly in time and space across a region may provide a non-arid climate zone. The same amount of water falling non-uniformly in space, or especially, time, may result in a semi-arid zone.

Arid, semi-arid, subtropical Group B expands at the expense of Group C, while Group C is busy moving north but not up in elevation. The norther parts of Group D (ie, much of Canada) diminishes in area and moves north and uphill.

Group E, the cold bits, decline in area, move north, and retreat uphill.

The most important thing in this graphic is probably the expansion of Group B, where we can and do grow some food but under somewhat difficult conditions, and the loss of Group C area. The breadbasket, it is shrinking.

The paper concludes,

… major Köppen climate types since 1950 have occurred worldwide and are almost entirely attributed to the observed anthropogenic increase in greenhouse gas concentrations. Model runs project accelerating anthropogenic-induced major climate type changes in the next decades. As the Köppen climate classification links the Earth’s climates with the qualitative features of the vegetation, results here indicate that observed climate changes might already be causing significant impacts on vegetation in areas where the major climate class has changed, and model projections imply increasing future impacts.

This is a problem.
