My only remaining Republican friend, Paul Douglas, provided this information.
Considering the top 20 most destructive California fires from Cal Fire’s database, 6 of those have happened in the last 10 months.
The worse so far is the Tubbs Fire last October, and that was HUGE. Nearly 6,000 structures were burned, 22 people were killed. The sixth on the list is the Carr fire, with just under 1,500 structures burned and six killed as of this writing, but that fire is still burning.
I’ll just add this. There was a moment in time between about 2 and 3 years ago, when it was apparent to me and many others that fires were getting worse. But the data was just coming in. There were studies that stopped their data roughly a year or a year and a half earlier that showed no statistically convincing increase. The delay in data range is normal. You get your data, clean it up, then Reviewer three adds eight months to the publication process, etc. so most studies are one or maybe two years late. Anyway, I was being told over and over again that I was wrong whenever I talked about fires. Much of that came from those who were sufficiently in the game to pretend they were not denying climate change, but who chose to get into the contrarian game despite the huge moral cost of doing so.
Well, we were right. We told you so. Shame.
Eventually, of course, the wildfires will stop. Like the surgeons say, the bleeding always stops. Eventually. One way or another.
In the past, most Americans (and probably many Europeans and Japanese) were either for or against nuclear. These days, a large middle area has opened up because nuclear is not fossil fuel, and may have an important role in future energy economies.
Having said that, building new nuclear plants have mostly moved into the pipe dream category. It is jut not happening. But maintaining and continuing to run existing plants is probably important, no what you think about nukes.
Here’s the thing. There are two reasons to shut down an existing plant. 1) It is too old or otherwise unsafe and needs to be closed. This is fairly rare but will become more common over the ext 30 years, and eventually, every one will be shuttered and converted over to nuclear waste storage facility. 2) it is too damn expensive to run.
We need to shut down the type 1 plants. We can have a conversation some other time about the strategy of replacing such plants with new nukes. We should not be shutting down type 2 plants now, because that puts pressure on the industry, which is relatively dumb when it comes to making long term decisions, to maintain or even build new methane, oil, or even coal plants.
But how do we save these type 2 plants from premature decommissioning?

When climate scientist Michael Mann and cartoonist Tom Toles wrote The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy, they had no idea how bad it was going to get. Perhaps they needed to be more alarmist.
Anyway, this overview of climate change politics and denialism, in both text and cartoon form, is out in a new edition that has an updated “in the times of Trump” chapter, and in paperback form.
Pick up your copy of The Madhouse Effect, excellent summer beach reading, today!
The award-winning climate scientist Michael E. Mann and the Pulitzer Prize–winning political cartoonist Tom Toles have been on the front lines of the fight against climate denialism for most of their careers. They have witnessed the manipulation of the media by business and political interests and the unconscionable play to partisanship on issues that affect the well-being of billions. The lessons they have learned have been invaluable, inspiring this brilliant, colorful escape hatch from the madhouse of the climate wars.
The Madhouse Effect portrays the intellectual pretzels into which denialists must twist logic to explain away the clear evidence that human activity has changed Earth’s climate. Toles’s cartoons collapse counter-scientific strategies into their biased components, helping readers see how to best strike at these fallacies. Mann’s expert skills at science communication aim to restore sanity to a debate that continues to rage against widely acknowledged scientific consensus. The synergy of these two climate science crusaders enlivens the gloom and doom of so many climate-themed books?and may even convert die-hard doubters to the side of sound science.
The details are evolving, but the basic relationship is for real.

We, and by “we” I mean “Donald Trump and his Republicans,” are already in a position of disdain by most of the rest of the world for being only one of three nations not signed on to the Paris climate pact.
The other two countries were a) Syria, not really a country any more, and b) Nicaragua.
Nicaragua is now joining the pact, according to Vice President Murillo, reported here:
“It is the only instrument we have in the world that allows the unity of intentions and efforts to face up to climate change and natural disasters,” Murillo said.
Nicaragua, a poor Central American nation that is often threatened by hurricanes, was the only nation to reject the agreement in 2015, and has argued for far more drastic action to limit rising temperatures.
The latest round of negotiations take place after a string of powerful hurricanes ravaged Caribbean island nations and caused billions of dollars in damage along the Texas and Florida coastlines.
Climate scientists have said warmer air and water resulting from climate change may have contributed to the severity of the storms. The U.S. Environmental Protection Agency has disputed such claims as an attempt to “politicize” natural disasters.
The OCO-2, aka, Orbiting Carbon Observatory 2, is a satellite that measures CO2 in the atmosphere, using a spectrograph.
From a news article in today’s Science, “One of the crowning achievements of modern environmental science is the Keeling curve, the detailed time series of the concentration of atmospheric carbon dioxide (CO2) begun in 1958 that has enabled deep insights into the mechanisms of global climate change. These measurements were difficult to make for most of their 60-year history, involving the physical collection of air samples in flasks at a small number of sites scattered strategically around the globe and the subsequent analysis of their CO2 inventories in a handful of laboratories throughout the world.”
The purpose of the OCO-2 was to make these measurements much more accurate and efficient, and to provide more granularity in the details. The space craft was launched in July 2014, replacing an earlier OCO (OCO-1, if you like) which was launched in 2009.
Do not tell Donald Trump about this satellite. He’ll have it shot down.
Anyway, the current issue of Science Continue reading Watching the Earth breath from space: OCO-2 and measuring CO2
The news is bad, and is being widely covered. Here I just want to make a remark or two about the link between big fires and global warming.
As of last report, there are 15 known dead and 150 or more missing. Hopefully they are only virtually and not actually missing; there is a lot of confusion and communication resources are in many cases down.
Wild fires are tricky in more ways then one. It is easy to get caught in one (I’ve manage that myself), and it is hard to predict or fully understand why some years have more than others. There has been a long term trend nationally towards fewer wild fires, for several reasons, most of which have to do with human activities. The most significant part of that trend is that humans caused many, huge, often deadly wild fires in the past. The worst wildfire ever in Minnesota, in terms of Death toll, was during World War I and had mainly to do with farming and railroads being a bad mix. Cutting lots of land to farm provides the fuel, and in those days, railroads were travelling tinderboxes sparking fires everywhere they went.

It isn’t. Well, it is a little, but not totally. OK, it is, but actually, it is complicated.
First, you are probably asking about the Atlantic hurricane season, not the global issue of hurricanes and typhoons and such. If you are asking world-wide, recent prior years were worse if counted by how many humans killed and how much damage done.
With respect to the Atlantic, this was a bad year and there are special features of this year that were bad in a way that is best accounted for by global warming. But looking at the Atlantic hurricanes from a somewhat different but valid perspective, last year was worse (so far) and this year is ordinary, within the context of global warming. So, let’s talk about the global warming question first.
How Global Warming Makes Hurricane Seasons Worse
The effects of global warming on hurricanes in the Atlantic have two interesting features that must be understood to place this discussion in proper context.
First, we are having a bunch of bad decades in a row probably because of global warming. If we compare pre-1980, for a decade, with post 1980, or pre vs. post 1990, or anything similar, the more recent years have had more hurricanes than the earlier years. Comparing to even earlier time periods is tricky because of differences in available data (Satellites make a difference, probably, even with giant weather features like hurricanes). This is mainly due to increasing sea surface temperatures, but there are other factors as well.
Hurricanes are more likely to form when sea surface temperatures are higher. Higher sea surface temperatures can make a hurricane larger or stronger. Hurricanes will last longer if there is more, higher, hurricane-hot sea to travel over. If sea surface temperatures are high enough to cause hurricanes earlier in the year or later in the year, the hurricane season can be longer. Possibly, storms that in a non-warmed world would not have made it to “named storm” status are moved to that level of strength and organization because of the elevated sea surface temperature.
Sea surface temperature increases of small amounts cause large changes in hurricanes, and large changes in hurricanes cause larger changes in potential damage level. The increase in Atlantic sea surface temperatures over recent decades have probably been sufficient, according to my thumb-suck estimate that I strongly suspect is close to correct, to make about half the hurricanes that would have existed anyway jump up one category. Then, when hurricanes get stronger, the amount of damage they can do goes up exponentially. So the sea surface temperature increases we’ve see with global warming easily explain the fact that we’ve had more hurricanes overall, and stronger ones, over the last twenty or thirty years than during the previous years back to when the data are still pretty good.
Second, the science says this will get worse. There is one 2007 study (by Vecci and Soden, in Geophysical Research Letters) that suggests that maybe in the Atlantic, smaller size hurricanes will be less likely to form because of increased vertical wind shear, but that study does not mean much for larger or stronger hurricanes. This decade old study is constantly cited as evidence that global warming will not increase hurricanes in the Atlantic. Other studies show that the overall amount of hurricane activity, and the potential higher end of hurricane strength, and the size, and the speed at which they form, and the amount of water they can contain, and possibly the likelihood of a hurricane stalling right after landfall, go up. Up. Up. Up. One study says down and that word, “down” it resonates across the land like a sonic boom. The other studies say we can expect, and to varying degrees already see, up, up, up, up, up, and denial makes words like “up” and “more” and “worse” and “exasperated” dangerously quiet. Please don’t fall into that trap. Oh, by the way,the one study that says “down” has not been replicated and though experts feel it has some merit, it is far from proven and there are reasons to suggest it my be problematic.
Comparing the 2017 Atlantic Hurricane Season to Other Years
Funny thing about hurricanes: They exist whether or not they menace you. Every year a certain number of hurricanes (usually) form and wander about in the Atlantic ocean for a while, maybe hitting some boats, but otherwise doing little more than causing some big waves to eventually reach beaches in the Caribbean or the eastern US.
This year, we’ve had four major hurricanes so far. Harvey, which maxed out as a Cat 4, ravaged and flooded Texas and Louisiana. Irma, maxing at Cat 5, ravaged Florida after wiping out islands in the Leewards and doing great damage to Cuba and elsewhere in the Caribbean. Maria, maxing out as a Cat 5, did major damage in the Leewards and notably wiped out Puerto Rico. So, four Major Hurricanes formed in the Atlantic and hit something major.
Meanwhile, Jose, another Major hurricane at Cat 4 status, still spinning about in the North Atlantic, is one of those that hit nothing. And that’s all so far this year.
Last year, there were almost exactly the same number of named storms in total (so far) and just like 2017, 2016 had four major hurricanes.
You remember Matthew, which scraped the Atlantic coast and was rather damaging. But do you remember Gaston (Cat 3)? Nicole (Cat 4)? Otto (Cat 3)?
Gaston and Nicole wandered about in the Atlantic and hit nothing. Otto was for real, it hit Central America, but not the US, so from the US perspective, it counts as a non-hitting hurricane. Also, it was only barely cat 3 and weakened quickly.
From 2000 to 2016, inclusively, we have had an average of 15 named storms per year, with a minimum of 8 and a maximum of 28, with most years being between 10 and 16. So far 2017 has had 13 named storms. We may have a couple more. So, likely, we will be right in the middle.
For the same period, the number of hurricanes has ranged from 2 to 15 with an average of about 7. This year, we have had … wait for it … 7. We may or ma not get another one, not very likely two more. In other words, this is an average year for the number of hurricanes.
For the same period, the number of major hurricanes ranges from 0 (though only one year ad zero, it is more typical to have 2 in a low year) to 7, but again, 7 is extreme. It is usually from 2-5. The average is just over 3. This year, we have four. That’s pretty typical.
So, within the context that the last couple of decades has had a somewhat higher than average frequency of hurricanes, and probably more strong ones than previous decades, this we had a typical year this year.
Why does it feel different? Why is it in fact difference, with respect to the horror of it all? Because we had more landfalls, and more serious landfalls.
Keep in mind that Harvey could have hit Houston differently and done more damage. Keep in mind that Cuba beat up Irma, then Irma failed to strike Florida in just the right way to do maximum damage. Keep in mind that after wiping out Puerto Rico, Maria swerved quickly out to sea. In other words, keep in mind that this year could have been much worse than it was.
This is the point that you must understand: Any year can be like this year, or worse. And, with increasing sea surface temperatures and other global warming related factors, worse still.
I’ll just put this item from UCS here for your interest:
Study Finds Top Fossil Fuel Producers’ Emissions Responsible for as Much as Half of Global Surface Temperature Increase, Roughly 30 Percent of Global Sea Level Rise
Findings Provide New Data to Hold Companies Responsible for Climate Change
WASHINGTON (September 7, 2017)—A first-of-its-kind study published today in the scientific journal Climatic Change links global climate changes to the product-related emissions of specific fossil fuel producers, including ExxonMobil and Chevron. Focusing on the largest gas, oil and coal producers and cement manufacturers, the study calculated the amount of sea level rise and global temperature increase resulting from the carbon dioxide and methane emissions from their products as well as their extraction and production processes.
The study quantified climate change impacts of each company’s carbon and methane emissions during two time periods: 1880 to 2010 and 1980 to 2010. By 1980, investor-owned fossil fuel companies were aware of the threat posed by their products and could have taken steps to reduce their risks and share them with their shareholders and the general public.
“We’ve known for a long time that fossil fuels are the largest contributor to climate change,” said Brenda Ekwurzel, lead author and director of climate science at the Union of Concerned Scientists (UCS). “What’s new here is that we’ve verified just how much specific companies’ products have caused the Earth to warm and the seas to rise.”
The study builds on a landmark 2014 study by Richard Heede of the Climate Accountability Institute, one of the co-authors of the study published today. Heede’s study, which also was published in Climatic Change, determined the amount of carbon dioxide and methane emissions that resulted from the burning of products sold by the 90 largest investor- and state-owned fossil fuel companies and cement manufacturers.
Ekwurzel and her co-authors inputted Heede’s 2014 data into a simple, well-established climate model that captures how the concentration of carbon emissions increases in the atmosphere, trapping heat and driving up global surface temperature and sea level. The model allowed Ekwurzel et al. to ascertain what happens when natural and human contributions to climate change, including those linked to the companies’ products, are included or excluded.
The study found that:
<li>Emissions traced to the 90 largest carbon producers contributed approximately 57 percent?of the observed rise in atmospheric carbon dioxide, nearly 50 percent of the rise in global average temperature, and around 30 percent of global sea level rise since 1880.</li> <li>Emissions linked to 50 investor-owned carbon producers, including BP, Chevron, ConocoPhillips, ExxonMobil, Peabody, Shell and Total, were responsible for roughly 16 percent of the global average temperature increase from 1880 to 2010, and around 11 percent of the global sea level rise during the same time frame.</li> <li>Emissions tied to the same 50 companies from 1980 to 2010, a time when fossil fuel companies were aware their products were causing global warming, contributed approximately 10 percent of the global average temperature increase and about 4 percent sea level rise since 1880.</li> <li>Emissions traced to 31 majority state-owned companies, including Coal India, Gazprom, Kuwait Petroleum, Pemex, Petroleos de Venezuela, National Iranian Oil Company and Saudi Aramco, were responsible for about 15 percent of the global temperature increase and approximately 7 percent of the sea level rise between 1880 and 2010.</li>
“Until a decade or two ago, no corporation could be held accountable for the consequences of their products’ emissions because we simply didn’t know enough about what their impacts were,” said Myles Allen, a study co-author and professor of geosystem science at the University of Oxford in England. “This study provides a framework for linking fossil fuel companies’ product-related emissions to a range of impacts, including increases in ocean acidification and deaths caused by heat waves, wildfires and other extreme weather-related events. We hope that the results of this study will inform policy and civil society debates over how best to hold major carbon producers accountable for their contributions to the problem.”
The question of who is responsible for climate change and who should pay for its related costs has taken on growing urgency as climate impacts worsen and become costlier. In New York City alone, officials estimate that it will cost more than $19 billion to adapt to climate change. Globally, adaptation cost projections are equally astronomical. The U.N. Environment Programme estimates that developing countries will need $140 billion to $300 billion annually by 2030 and $280 billion to $500 billion annually by 2050 to adapt.
The debate over responsibility for climate mitigation and adaptation has long focused on the “common but differentiated responsibilities” of nations, a framework used for the Paris climate negotiations. Attention has increasingly turned to non-state actors, particularly the major fossil fuel producers.
“At the start of the Industrial Revolution, very few people understood that carbon dioxide emissions progressively undermine the stability of the climate as they accumulate in the atmosphere, so there was nothing blameworthy about selling fossil fuels to those who wanted to buy them,” said Henry Shue, professor of politics and international relations at the University of Oxford and author of a commentary on the ethical implications of the Ekwurzel et al. paper that was published simultaneously in Climatic Change. “But circumstances have changed radically in light of evidence that a number of investor-owned companies have long understood the harm of their products, yet carried out a decades-long campaign to sow doubts about those harms in order to ensure fossil fuels would remain central to global energy production. Companies knowingly violated the most basic moral principle of ‘do no harm,’ and now they must remedy the harm they caused by paying damages and their proportion of adaptation costs.”
Had ExxonMobil, for example, acted on its own scientists’ research about the risks of its products, climate change likely would be far more manageable today.
“Fossil fuel companies could have taken any number of steps, such as investing in clean energy or carbon capture and storage, but many chose instead to spend millions of dollars to try to deceive the public about climate science to block sensible limits on carbon emissions,” said Peter Frumhoff, a study co-author and director of science and policy at UCS. “Taxpayers, especially those living in vulnerable coastal communities, should not have to bear the high costs of these companies’ irresponsible decisions by themselves.”
Ekwurzel et al.’s study may inform approaches for juries and judges to calculate damages in such lawsuits as ones filed by two California counties and the city of Imperial Beach in July against 37 oil, gas and coal companies, claiming they should pay for damages from sea level rise. Likewise, the study should bolster investor campaigns to force fossil fuel companies to disclose their legal vulnerabilities and the risks that climate change poses to their finances and material assets.
Harvey the Invisible Rabbit: Did not exist.
This is a picture of some men.
Since they are men, they have some abilities. They can, for example, knock each other over, and they can play with balls. This is what men do, and this is what these men can do.
They are also men. They can also knock each other over, and they can also play with balls. But the NFL football players are much better at knocking each other over, and you wouldn’t believe how great they are at playing with balls.
They are NFL enhanced. They are trained, embiggened with special diets, and they are clad with armor and vibrant, often scary, colors.
This is a picture of a hurricane from 1938.
It was a big one; It did lots of damage when it slammed into New England and New York.
A hurricane is a large storm that forms in the tropics, and sometimes hits land. The energy from a hurricane comes from a combination of the earth’s spin, trade winds, and so on, but mainly, from the heat on the surface of the sea. The rain that falls from the hurricane also comes mainly from the sea surface indirectly, and any water that evaporates into the atmosphere.
This is a picture of Harvey the Hurricane, the remnants of which are still circulating around in Texas.
Harvey is a lot like the 1938 hurricane, in that it formed in the tropics, in the Atlantic, and was a big spinny thing. It got its energy in the same way, and formed in the same way, and both slammed into land and scared the crap out of everybody.
But they are different, the 1938 Hurricane and Harvey the Hurricane. How are they different? Have a look at this map:
The pairs of photos above show “then” and “now” for two different things (men and hurricanes). This map shows both then and now in the same graphic. This map represents the current sea surface temperature anomalies, meaning, how much warmer or cooler the current sea temperatures are compared to the same time of year but at some time in the past, averaged over a long period, in this case, from 1971-2000. Global warming was well underway during that period, so present sea surface temperature readings that are above that baseline are not only high but are actually very high, because the baseline is high.
In this map, red is more, blue is less. Look at all the nearly ubiquitous more-ness in sea surface temperatures around the world. That causes the atmosphere across the entire globe to potentially contain much more water vapor than it could have contained during that that baseline period. Look at the sea surface temperature anomalies for the gulf of Mexico, where Harvey formed. They are high. This means that any hurricane that formed over that extra warm water will be stronger, and any tropical storm system that occurs pretty much anywhere on this map (or round the other side of the Earth as well, for that matter) will contain more water, than it would if it existed and all else was equal several decades ago.
This is a picture of a Unicorn.
A unicorn poops rainbows and pees mimosas. Or so I’m told. This is another view of Harvey the Hurricane.
What is the difference between the unicorn and Harvey? Harvey is real, and the unicorn is not.
I won’t quote you or give you links. Why? Because I find this whole thing a bit too embarrassing. But here is the thing. Otherwise intelligent and well informed individuals have stated in various outlets, including major media, and including twitter, that it is simply inappropriate to claim that Harvey the Hurricane is in any way global warming enhanced.
This is wrong. There is no such thing as a storm of any kind that is not a function of the current climatology. The current climatology has widespread and persistent, and in many cases alarmingly high, sea surface temperature anomalies. There will not be a tropical storm, including hurricanes, that escape the physics and poop out rainbows and pee mimosas. They will all be real. They will all have greater power and more moisture than they otherwise would have, had they formed decades ago before the extreme global warming we have experience so far.
There was a time when Harvey was a rabbit, an invisible rabbit only seen by a delusional character in a movie, played by Jimmy Stewart. Today, we have Harvey the Unenhanced Storm, playing that role. It is a fiction, something seen by a few but that is no more real than the above depicted unicorn.
As I was writing this post, Michael Mann posted an item in the Guardian that makes this case.
He says (click here for the whole story):
Sea level rise attributable to climate change – some of which is due to coastal subsidence caused by human disturbance such as oil drilling – is more than half a foot (15cm) over the past few decades … That means the storm surge was half a foot higher than it would have been just decades ago, meaning far more flooding and destruction.
… sea surface temperatures in the region have risen about 0.5C (close to 1F) over the past few decades from roughly 30C (86F) to 30.5C (87F), which contributed to the very warm sea surface temperatures (30.5-31C, or 87-88F).
… there is a roughly 3% increase in average atmospheric moisture content for each 0.5C of warming. Sea surface temperatures in the area where Harvey intensified were 0.5-1C warmer than current-day average … That means 3-5% more moisture in the atmosphere.
That large amount of moisture creates the potential for much greater rainfalls and greater flooding. The combination of coastal flooding and heavy rainfall is responsible for the devastating flooding that Houston is experiencing.
… there is a deep layer of warm water that Harvey was able to feed upon when it intensified at near record pace as it neared the coast….
Harvey was almost certainly more intense than it would have been in the absence of human-caused warming, which means stronger winds, more wind damage and a larger storm surge…
Mann mentions other effects as well, but I’ll let you go read them.
The extra heat at depth Mann mentions is now recognized as responsible for the extra bigness and badness of some other famous hurricanes as well, such as Katrina and Haiyan. Harvey might be a member of a small but growing class of hurricanes, deep-heat hurricanes I’ll call them for now, that simply did not exist prior to global warming of recent decades. Further research is needed on this, but that’s the direction we are heading.
Climate scientist Kevin Trenberth recently noted that “The human contribution can be up to 30 percent or so up to the total rainfall coming out of the storm,”
Aside from Michael Mann’s Guardian article, he has this facebook post making the same argument.
Harvey the Hurricane is real, and so was the 1938 Hurricane. Climate change enhancement of Harvey is real, but unicorns are not. Sadly.
I really thought we had stopped hearing this meme, that “you can never attribute a given weather event to climate change.” But, apparently not. That is a statement that is technically true in the same way that we can’t really attribute an Alberta Clipper (a kind of snow storm) to the spin of the Earth. Yet, somehow, the spin of the Earth is why Alberta Clippers come from Alberta. In other words, the statement is a falsehood that can never be evaluated because it is framed incorrectly. Here is the correct framing:
Climate is weather long term, and weather is climate here and now. The climate has changed. Ergo … you fill in the blank. Hit: Unicorns are not involved.
