What Climate Change Denialism Looks Like

I generally ignore climate change denialists on Twitter. I use The Zapper to do that, and it works great, better than blocking. But sometimes I check my Twitter feed on something other than Chrome on my own desktop or laptop and then I see them, and occasionally engage. When I do, I often see troubling or annoying visual tropes that seem to go along with this breed. Guns, exploitative photos of women, flag-draped symbols, and Nazis. That sort of thing.

So, this morning I put together a collage of images off the Twitter home pages of just the last handful of Denialists who were obsessively tweeting and retweeting to or about me this morning. For your enjoyment:

Scared? Yeah, I didn’t think so.

Are the scared? Given how well armed they are, it would seem so. Trying to push the world in to climate apocalypse so they can do the survivalism thing? Interesting idea.

Climate Change Science Search Engine

This search engine will scan a large number of sites known to have good climate change related information on them.

Below is a list of sites scanned. If you know of a site that is not included here but that should be, please put a link in the comments. Don’t bother with climate science denialist sites, they will not be added.

Also note that many sites are parts of larger domains. So if the site you suggest is already part of, for example, Scienceblogs, The Guardian, etc. then it is already on the list by default. This, of course, means that some of the hits from this search engine will be not “certified” as part of this excellent list of sources because a large domain could have science denialism lurking around on it. But for the most part, the results of this search should be pretty useful. Also, since some very large domains are searched you may want to use some climate change related keywords. For example, searching for the term “hiatus” by itself will get you links for broadway shows taking a hiatus. But searching for “global warming hiatus” will get you (mostly) links about the so-called “pause” in global warming.

There are also aggregating or linky sites on this list so there may be some redundancy in your search results, but there is not much one can do about that.

Weather Whiplash, and What Does (The) Fox Say?

Paul Douglas send me this photo: "Check out the piles of melting slush in the foreground; looks like half a foot (?) of dirty snow in that one clump. This takes weather whiplash to a new (and ridiculously jaw-dropping) level. Photo courtesy of Dana Cottingham Fricke, from Concord, Illinois."

The biggest loss of containers from a container ship (that didn’t just plain sink) happened a few days ago as the Svendborg Maersk was battered with hurricane like conditions including Waves Of Unusual Size generated in the Global Warming Enhanced megastorm, while at the same time tornadoes, some snownadoes, touched down in various places in the US.

Fox News is lost and confused. From Media Matters:

Snowstorms and cold weather chills swept from the Midwest to the East Coast in January, closely followed by conservative media snow-trolls casting doubt on global warming. But what the conservative media didn’t mention was that the world as a whole was experiencing warm temperatures, leading to January becoming the 347th consecutive warmer-than-average month and the fourth warmest on record.

On February 20, the National Oceanic and Atmospheric Administration (NOAA), released the findings that January 2014 experienced global temperatures 1.17°F warmer than the 20th century average, making it the fourth warmest January on record. NOAA data shows that the last time the planet experienced a month colder than the 20th century average was February 1985 — 29 years ago.

How could this be, when Fox News is telling you that the snowstorms in the United States are a reason to doubt global warming? The answer lies beyond the lower 48 states, which make up only 1.5% of the Earth’s surface. While some regions in the contiguous U.S did experience a colder-than-average month (none a record cold month), most of the globe did not:

More on the "Drunk Arctic"

Mother Jone’s Climate Desk has an excellent and important interview with Jennifer Francis and Kevin Trenberth. I can’t really comment on it now due to lack of time but I think it is time for me to update my AA->QR->WW linkage post based on this discussion. I’ll also bring this into my next talk on Climate Change, possibly in Plymouth sometime during the next couple of months (still being arranged).

Anyway, CLICK HERE to get the blog post by Chris Mooney which includes the stream of the Inquiring Minds Podcast.

Also, thanks to Chris for asking the question I suggested. Very interesting answer.

John McCain and Newt Gingrich are acting like Middle School Bullies

I’d love to describe the details to you but I don’t think I can ever do as good a job as Representative Henry Waxman and Senator Sheldon Whitehouse. They wrote a letter to McCain and Gingrich. Gave ’em a good shellacking, they did. I love this letter so much I’m giving it to you three times. First, as a picture of the letter because it is so cool looking. Then, as a transcript so it is searchable. Then, as a link to a PDF file.

And now, here is the text, from here:

February 20, 2014

The Honorable John McCain
241 Russell Senate Office Building
Washington, DC 20510

The Honorable Newt Gingrich
Gingrich Productions
4501 North Fairfax Drive
Suite 900
Arlington, VA 22203

Dear Senator McCain and Mr. Gingrich:

Over the weekend, Secretary of State John Kerry gave a powerful and important speech in Indonesia about the dangers of climate change. Secretary Kerry accurately said, “When I think about the array of global threats … terrorism, epidemics, poverty, the proliferation of weapons of mass destruction … the reality is that climate change ranks right up there with every single one of them.”

Your reaction was disappointing. Senator McCain asked, “On what planet does he reside?” Mr. Gingrich called the Secretary “delusional” and “dangerous to our safety.”

You should know that Secretary Kerry’s assessment of the risks we face is consistent with those of national security experts of unimpeachable credentials. For example:

• Admiral Samuel J. Locklear III, Chief of U.S. military forces in the Pacific region, said that the biggest long-term security threat in the region is climate change because it “is probably the most likely thing that is going to happen . . . that will cripple the security environment, probably more likely than the other scenarios we all often talk about.”

• General Anthony Zinni, the former Commander-in-Chief of U.S. Central Command, warned, “You may also have a population that is traumatized by an event or a change in conditions triggered by climate change. … [T]hen you can be faced with a collapsing state. And these end up as breeding grounds for instability, for insurgencies, for warlords. You start to see extremism. These places act like Petri dishes for extremism and for terrorist networks.”

• Robert Gates, the former Defense Secretary, said, “over the next 20 years and more certain pressures – population, resource, energy, climate, economic, and environmental – could combine with rapid cultural, social, and technological change to produce new sources of deprivation, rage, and instability. … I believe the most persistent and dangerous threats will come less from ambitious states than failing ones that cannot meet the basic needs – much less aspirations – of their people.”

• Admiral Michael Mullen, the former Chairman of the Joint Chiefs of Staff, stated, “The scarcity of an potential competition for resources like water, food and space, compounded by the influx of refugees if coastal lands are lost, does not only create a humanitarian crisis but it creates conditions of hopelessness that could lead to failed states and make populations vulnerable to radicalization.”

• Admiral John Nathan, former Commander of the U.S. Fleet Forces, predicted, “There are serious risks to doing nothing about climate change. We can pay now or we’re going to pay more later.”

• James Clapper, the Director of the National Intelligence, testified, “there will almost assuredly be security concerns with respect to … energy and climate change. Environmental stresses are not just humanitarian issues. They legitimately threaten regional stability.”

• Thomas Fingar, the former Chairman of the National Intelligence Council, concluded, “We judge global climate change will have wide-ranging implications for US national security interests.”

• Hans Blix, the former chief UN weapons inspector, said he thought climate change posed a greater threat to the planet than nuclear proliferation.

You may also want to review the 2010 Quadrennial Defense Review, which called climate change “an accelerant of instability or conflict” that “could have significant geopolitical impacts around the world, contributing to poverty, environmental degradation, and the further weakening of fragile governments.”

These concerns about the profound risks of climate change are shared by distinguished world leaders. Last month, Kofi Annan, the former Secretary General of the United Nations, wrote in the Washington Post, “Climate change is the biggest challenge of our time. It threatens the well-being of hundreds of millions of people today and many billions more in the future.” Christine Lagarde, Managing Director of the International Monetary Fund, said last year that climate change has the “potential for major social and economic disruption.” And Dr. Jim Yong Kim, President of the World Bank Group, stated that if we fail to confront climate change “we could witness the rolling back of decades of development gains and force tens of millions more to live in poverty.”

You may also want to reflect on what Robert Rubin, the widely respected former Treasury Secretary, said just last month about climate change: “There are a lot of really significant, monumental issues facing the global economy, but this supersedes them all.”

Senator McCain made a particular point of criticizing Secretary Kerry for talking about climate change “when we have got 130,000 people in Syria killed.” This is an inaccurate criticism because Secretary Kerry has been devoting extensive attention to Syria. It is also uninformed. There are experts who believe that climate change and the extended drought is one of the underlying causes of the conflicts in Syria. As the New York Times columnist Thomas Friedman wrote, tensions in the Middle East have been “driven not only by political and economic stresses, but, less visibly, by environmental, population and climate stresses as well. If we focus only on the former and not the latter, we will never be able to help stabilize these societies.”

Secretary Kerry needs allies in this fight for the future of our planet. History will not look back and fault him for leading the charge to prevent the worst impacts of climate change while we still have time. But history may question why Republican leaders who were once their party’s champions on climate change fled the field at a crucial moment.

Sincerely,

Rep. Henry A. Waxman

Sen. Sheldon Whitehouse

Shame on the BBC: False Balance in #ClimateChange discussion

The BBC stepped in it. First, they engaged in a totally absurd “false balance” presentation regarding climate change, then in response (link below) they aired very reasonable complaints by listeners, and to this, they responded officially that everything is fine, you can go home and lock your doors and windows, nothing to see here, our balance is in balance, thank you very much. Or words to that effect. If I was British I would be ashamed of the BBC for this, but since I’m not British I’m peeved.

Should the Today programme have invited Lord Lawson, a former Chancellor of the Exchequer and now chairman of the Global Warming Policy Foundation, to comment on climate change? On Thursday morning, as the floods across Britain continued to make the headlines, Feedback listeners poured scorn on a Today programme discussion between Lord Lawson and Sir Brian Hoskins, a government climate change adviser from Imperial College in London. We’ll hear why they were so angered by the debate.

Click here to listen. I think the link is already cued up where you need to be.

The commenter just after 20 minutes was brilliant.

Paul Douglas on Climate Change

Last night I attended a talk by meteorologist Paul Douglas, at the Eden Prairie High School. The talk was “Weird Weather: Minnesota’s New Normal? Our Changing Climate and What We Can Do About It,” and it was sponsored by Environment Minnesota, Cool Planet, and the Citizens Climate Lobby. I didn’t count the number of people in the audience but it was well attended (over 100, for sure). Extra chairs had to be brought in.

You probably know of Paul Douglas either because of his own fame or because I often link to (or facebook-post) his blogs at Weather Nation or the Star Tribune, and I frequently post his videos. Paul is an Evangelical Christian Republican who insists that we must adhere to the data and the science. He is outspoken on climate change, global warming, and science denialism, and he is sincere, thorough, and forceful in these areas. I consider him to be a very close ally. The contrast between what Republicans seem to think as a cultural group, and what Evangelical Christians seem to think as a cultural group, and what Paul advocates makes him, in his own words, a Human Albino Unicorn.

The talk, as something organized by three environmental activist groups, had the usual suspects in attendance. I recognized several fellow activists from the Twin Cities area, including individuals from 350.org and Obama’s OFA. I had the sense that I was attending a Democratic Farm Labor (that’s what we call Democrats ‘round these parts) convention being run by a Reasonable Republican.

Needless to say, Paul provided an excellent presentation that would have provided any skeptic sitting near the fence a gate to pass through when the moment was right. His talk would have likely convinced any dyed-in-the-wool septic in attendance to at least be quiet about the skepticism and let others take the conversation for a while. Paul tied together several reasons to respect the science and to act on it, touching on diverse perspectives including personal morality, concern for our children and grandchildren, business acumen, responsibility for the Earth’s environment, conservative political thinking, and (briefly, he did not belabor this point) religion.

Since I’m all into climate change and stuff, and give presentations on the topic myself, there wasn’t much new that hit me on the head, though I saw a lot of other heads being whacked with facts and ideas in the room. But there were two things that gave me a double take. They were both brought up in the question and answer period.

One came as part of the answer to the question, why isn’t there more climatology, and in particular, climate change, in with the weather reporting on local TV? I should note right away that this is one of the reasons you should read Paul’s blog. You get the weather AND the climatology. If you are in the Twin Cities area, his Strib Blog is the place to go. If you are elsewhere in the US or beyond, his Weather Nation blog is the place to go. There is a lot of overlap but somewhat different regional coverage. Anyway, Paul’s answer included this: On news TV, global warming is toxic. Meaning, specifically, stating the basic fact that global warming is established science is not really allowed on standard news TV, local or national. The False Balance sells, admitting the facts is boring. More importantly, stating that climate change is real and important will piss off 30% of the audience and the people running the news shows don’t want that. The anchors, including the weather reporters, are to be beloved, not reviled. So “just don’t do that” is the policy in newsrooms.

The other whack on the head was in relation to a question that I thought at first was a bit obnoxious but then I realized it was one of those questions that IS obnoxious but usefully so, and necessary. The question was, in short, “Is there anybody in this room that didn’t already believe in global warming before this talk … was anyone’s mind changed?”

One person raised their hand to indicate a changed mind (everyone cheered) but this apparent fact was left on the table: This talk didn’t do anything but reinforce everyone’s existing position. That was a bit depressing at first.

However, I think the implication and factual basis of that question were wrong. First, there were probably several climate change denialists in that room, but they simply chose not to raise their hands either because they would have been deeply embarrassed or because their mind was not changed. I recognized one person that I’ve encountered before who is a denialist, and he remained silent. I have given talks on climate change attended by people I know are denialists and they’ve stayed silent or asked questions that did not indicate their denialism. So, yes, there are people in the audience who do not “believe in global warming” and I suspect a talk like Paul’s would have an effect on them, eventually.

Also, this: Nobody should “believe in global warming.” That’s where Paul separates his own beliefs (i.e., that there should be Republicans at all 🙂 … or his religious beliefs which are based on faith) and a scientific approach to life, including both business and climate. A different question might have been, “Was there anything in Paul Douglas’s talk that you didn’t know before, about climate change, that you now know? Did you learn anything new either about climate or about how to talk about climate, in this talk?” The answer to that would have been, for almost everyone in the room, “Yes, many things.”

And this is a very important reason why “preaching to the converted” is important. Anti-climate science industrial interests spend hundreds of millions of dollars annually on public engagement to develop and shore up their political position. Hundreds of millions of dollars a year buys a lot of rhetoric, but it does not buy one drop of truth. But truth by itself is not enough. Grassroots organizing and the power of citizenry, when armed with the truth, is enough to effect major change if it is sustained long enough over a sufficient range of the population (and done well). Last night’s talk was a highlight moment for local and regional activism in support of the planet we live on. Those who attended will keep Paul’s talk with them for decades, and it will supply them with tools and ideas, and perhaps most importantly, inspiration and hope, regardless of their personal staring point.

So, yeah, it was a great talk.

Olympic Snow #Sochi2014

It has become difficult to rely on natural cold and snow even in traditional winter sports venues. This is because of increased temperatures caused by global warming. This may not be the biggest problem caused by climate change, but it is one that has attracted a certain amount of helpful attention. Perhaps the North American visitation of the Arctic Vortex, which has made some people think that climate change is not real, is partly offset by a Winter Olympics with more than its share of problems, including injuries and lost medals, caused by crappy snow conditions.

Also, it is kind of a “First World Problem.” Such problems tend to receive extra attention and the demand for solutions may be more likely addressed. I imagine that the slopes of the better ski resorts are populated by a relatively high proportion of people who assume climate change can’t really affect them (because not much does), and perhaps by a larger percentage of people who feel, incorrectly, to be financially threatened by measures to curb climate change.

Meanwhile, science not only tells us that global warming is real, but it also tells us how to adapt, at least a little. From the American Chemical Association, a video on how they make snow:

Abrupt Climate Change

First, let me note that if you are not a regular reader of Peter Sinclair’s “Climate Denial Crock of the Week” you should be.

Peter’s latest video is “Abrupt Climate Change, and the Expected Unexpected”

Senior Scientists discuss the potential for sudden disruptions of human and natural systems as a consequence of climate change.

Today's Weather #Icestorm #Noreaster #Flooding #RuhRoh

For the first time in weeks we are experiencing warm weather in central Minnesota (it is now 21 degrees F) with a bit of snow off and on. But elsewhere there are interesting things happening. First, in far northern California and the Pacific Northwest there will be rain. A LOT of rain. That’s great because it will help a little with the drought. But, it will also probably cause some severe flooding.

Also, everywhere on the east coast from Atlanta up to New England is experiencing some kind of bad.

Snomageddonapocalypse.  On fire.
Snomageddonapocalypse. On fire.
A friend of mine in the Raleigh-Durham area told me last night that he drove off the road three times in three miles, and normally he does no drive off the road more than once in three miles! I can’t be sure of the attribution of the photo shown here of the Fiery Snomageddonapocalypse, but it seems to be someone from North Carolina. Found on facebook.

More than three quarters of a million people have been without power across 14 states. New York City and DC are getting hammered or will soon.

You all know this from the news. I just wanted to add some context.

Here I’ve combined an estimation of precipitation over the next 7 days from here, with a map of the Jet Stream from here.

You can see the relationship between overall weather patterns as indicated by the Jet Stream and the precipitation. The same curvy jet stream that formed the Ridiculously Resilient Ridge causing drought in California will now cause deluge, and this was also related to the Arctic Vortex visiting the central part of North America for weeks on end. This pattern of whacky weather, with major drought interdigitated with heavy rain, ice in Atlanta, and all that, is what we call Weather Whiplash. And there is probably a link between Anthropogneic Global Warming and this extreme weather.

Stay safe.

Oh, by the way, what does that photo of Atlanta, the image featured above the post, remind you of? …

Let’s just hope that Zombies are not part of the forecast for the remainder of the week!


More on climate change here, and more on severe weather here.

The Alaskan Winter That Never Was?

I had heard it was warm in Alaska, but holy moly, I didn’t know it was THIS warm. Above is an anomaly map showing the Drunken Arctic Air in central and eastern Canada and the US in contrast with the very (relatively) warm air over western Canada and Alaska. Remember, these are anomalies, not absolute temperatures. But still, it is warm enough in at least parts of Alaska that lakes that are normally well frozen by now are not frozen at all and may not even freeze this winter.

Here are photographs taken by A.M.Mueller on January 25th 2014 in Skilak Lake, Kenai Peninsula, Alaska, and passed on for posting, with some commentary.

Alaska Kenai Peninsula, January, -- 60F, at least in the sun … in the 50s without sun. Super warm for weeks on end.

The Global Warming Hiatus, 2013, And Some Data (#FauxPause)

First, there is no hiatus. Climate science skeptics claim that warming stopped in 1998. It didn’t. Stefan Rahmstorf has a nice post placing 2013 in context with the most recent data, HERE. Just click the “translate” button to read it in your favorite language.

UPDATE: Stefan’s post is now HERE on Real Climate, in English.

Stefan has a bunch of great graphics that you will enjoy. Following his lead I’ve decided to make a graphic or two myself.

First, the data. NASA has this data to which people often refer when discussing global warming. I took that database and fixed it up a bit. I deleted the first year because there’s some missing data and who cares about only one year anyway. Then, I converted all the values to degrees C rather than hundreds of degrees off a baseline. I also calculated a rank for each year in reference to the entire database. You can download the data as a comma delimited file here. Let me know if that link doesn’t work for you, I’ll be happy to send you the file. Please cite the original (linked to above) if you use this.

Using these data I made this handy graphic showing “surface temperatures” (air and sea surface) over time from 1881 to the present.
GlobalAverageTemperatureOverTime

When people talk about the hiatus in climate change, or the pause in climate change, what this means is that the slope of the temperature curve for a particular period of time is at or near zero, or negative. What actually happens is that the slope of the curve for a given interval, say 10 years, goes up and down over time. If the temperature was varying around a mean, and not going up over time, the sum of those slopes would be zero, but if there is an average increase in temperature the sum of all the different slopes (of a given interval) one can calculate will be positive.

This is actually a slightly strange way of looking at the data, but I think it is constructive, especially given that the so-called-pause is a dead horse and we are hear to beat it. Look at the chart above. Imagine taking any given ten year period and calculating a slope for that period. Then another and another and another, until you’ve measured out a slope for every ten year period … not just every ten years, but every possible interval of ten consecutive years. This would be a “moving slope” and a graph of it would look like this:

10-year-moving-slope-of-GlobalAverageTemperatureOverTime

What this shows is that for the vast majority of ten year intervals since 1889 (so the first interval is 1880-1889) the slope of the temperature curve is positive, going up, increasing. It also shows what looks like a remarkably periodic increase and decrease in this slope, with only a few dips below zero. That’s presumably due to oscillations such as ENSO or other factors. Also, most of those dips are from fairly far back in time, and this happens rarely in recent years. We are currently in a period of positive change (upward temperature swings) but currently reduced. But if you look at this graph you can see that there are OFTEN periods of time when the upward slope is very high and other periods when it is very low but still above zero almost always. I hope this helps put the “hiatus” into perspective.

I also made this graph of each year’s rank for the entire period represented by the data set.

Screen Shot 2014-01-26 at 7.03.12 PM

Again, this is a slightly unusual way of depicting the data, but it may be helpful. All of the highest ranked years … top ten or so … are from very recent time. The graph has grid lines at every 10 ranks. This lets you quickly identify the period of time over which the top 10, or 20, or 30, or whatever, warmest year according to this data set occurred. There are no top ten years prior to about 1998. All of the top 30 warmest years post date the early 1970s. And so on.

OK, so let’s look at the hiatus again. The hiatus is supposed to be a period of no global warming since 1998. Here’s a closeup of the original chart (above) for that period of time:

TheSoCalledHiatus

What we see here, with the trend line included to make it easier to read, is an increase in global temperature, on average, during this so called hiatus period. But, by picking 1998 as a starting point, climate science denialists have managed to flatten the curve out quite a bit. That’s called cherry picking.

Now let’s arbitrarily double the period of interest, to include the entire so-called hiatus and the same amount of time back before the so-called hiatus. What does the graph look like then? Here, I’ve tried to keep all the scales the same so you can see the shorter “hiatus” period as part of this larger graph. You can also see that 1998 was an exceptionally warm year, which is why you’d want to pick it as the beginning of your fake hiatus period if you were a damn liar. Have a look.

TheSoCalledHiatusTwice

Let’s look at those so called hiatus years in yet another way. Here, we have the graph of the temperature by years (with the upward sloping trend line indicating continued warming even though it is supposed to be a “pause”) and at each node I’ve written in the rank order of the year for the instrumental record. Note that tied years share a number. Basically, this period of “hiatus” is a very very warm period indeed, with temperatures trending upward during the entire period, looking only at the earth’s surface. (Elsewhere we’ve discussed how there is also heat going into the oceans. See links below.)

RankOrderDuringHiatus

Since the climate science denialists have chosen a period of time of 16 years to describe a so-called “hiatus” which is not really a hiatus, I thought it would be fun to chunk out the data for the entire time period into 16 year intervals, starting with the most recent and going back to 1886. When viewed using these time intervals, we see overall warming with the most recent years seeing accelerated warming. Have a look:

These are all first drafts and if I get reasonable suggestions I may make new versions with corrections, additions, etc.

Global warming. It’s for real.

The Recovery of Arctic Sea Ice Extent

During the northern Winter, much of the Arctic is covered with sea ice. Some of this ice melts during the summer, then it regrows. Over recent years, the amount of ice loss in the summer has tended to increase, almost every year, year after year. In 2012 the loss of sea ice was extreme, falling for much of the melting and re-freezing cycle below any year seen before.

The year 2013 was also extreme, with more ice melting away in the summer than almost every previous year, but not to the extent seen in 2012.

Climate science denialist used this fact to make up a story. In this case, the word “story” is a nice way of saying “lie.” The denialists claimed that Arctic Sea Ice was “recovering.” Well, it was, sort of. Sea ice in 2013 was more extensive than the previous year, but still at a very low level. Part of the “recovery” story was the assertion that the sea ice would not return to “normal” levels year after year. A cycle was simply repeating itself.

The problem with the cycle idea is that there is no really a cycle. In a non-global-warming world there probably would be something that looks like a cycle, or at least a decadal (or something) fluctuation from year to year. But with global warming we have seen a phenomenon called “Arctic Amplification.” This is the warming of the arctic region to a greater extent than most of the rest of the plant. With Arctic Amplification we have seen sea ice extent drop nearly every year for about 20 years. I’ve written about the importance of this here. This does not seem to be a cycle, but rather, a downward trend. The fact that 2012 was extreme makes 2013 look like a reversal, but there is no reason to think that it is.

Now it is Winter in the Arctic. When we look at sea ice extent, we see something interesting. The current level of sea ice is hugging the 98th percentile of observed sea ice extent, at the lower margin. More interestingly, when we compare 2012, the “recovery” year, with the current ice extent, it turns out that the current ice extent is less than the “recovery.”

Here’s a graph from the National Snow and Ice Data Center:

Jim Pettit, commenting here, noted, “…just wanted to note that denialists have now gone silent on the “recovery” of NH sea ice extent, since that reading is currently several hundred thousands square kilometers lower than it was on this date in 2012, the year of the record melt-out.”

I can not verify Jim’s statement about denialists going silent, but it seems right. I’m not sure what the best way to measure that would be (seems like a lot of work) and I don’t think we have to. Paying too much attention to denialist rhetoric is a waste of time. But I think he may well be right. The answer to the statement “Global warming is not real because SEA ICE RECOVERY” was, several weeks ago, “Right … recovery from an extreme year, but the ice is still less than almost every observed previous year.” The answer to that same assertion is now “Um …. nope.”

The graphic at the top of this post speaks to volume rather than extent. I put it there just to remind everyone that volume is probably even more important, as this reflects loss of long-term ice and also involves a lot more global-warming related energy. If the huge volume of sea ice wasn’t there to melt in the summer, that heat would be elsewhere in the system. When there is virtually no “old ice” left … well, that will be like the ice in your drink melting. It (your drink, the planet, whatever) will get warm and icky.

Climate Change Conversations: Tonight and tomorrow

Tonight, at 7:00 PM, I’ll be giving a talk at the Stillwater Critical Thinking Club on climate change, focusing on sea level rise and weather whiplash. We’ll be discussing the Arctic Vortex as part of that.

The Global and Local Impacts of Climate Change

Anthropogenic Climate Change, also misleadingly known as “Global Warming,” has emerged as a significant reality affecting societies and economies around the world and at home. In this talk we’ll examine the contentious questions of changes in weather patterns and sea level rise. Both of these effects of warming have already had impacts and these impacts are expected to increase in the future. What does the science say about “weather whiplash,” severe storms, and the rise of seas in the near and longer term future, how certain are we of what may happen, and how severe might these impacts be?

Details Here.

Tuesday night, at 9:00 PM Eastern (8:00 PM Central) I’ll be doing a tweeting thing with the MomsRising organization. To watch or participate, follow the hashtag #EcoTipTue.

The Polar Vortex Might Be Caused By Al Gore (and other Liberals)

Everyone laughed … earlier today … when Rush Limbaugh claimed that the Polar Vortex, the ginormous weather phenomenon that brought so much cold to Canada and the United States over the last few days, was created by Liberals.

If Liberals can indeed create a planetary-level weather phenomenon like the Polar Vortex, then Liberals are very powerful indeed and should not be messed with. Just sayin’

Anyway, people made fun of Rush Limbaugh for saying this. Peter Gleick, who blogs here, went so far as to tweet a Google ngram he did showing that the peak of use of the term “Polar Vortex” happened way before the recent media frenzy associated with this recent weather event.

But I think Peter missed the point. Rush Limbaugh may be smarter than he looks. Here, I’ve combined the Google ngram for “Polar Vortex” with a red box showing the approximate duration that Bill Clinton and, most notably, Inconvenient Truth author Vice President Al Gore were in the white house. Have a look:

PolarVortexAsLiberalPlot

Clearly, there is a link. The fact that “Polar Vortex” initially peaks before the Clinton-Gore administration is obviously because the Liberals were gaining power during that time, in order to take over the White House.

This certainly gives new meaning to the phrase “Thanks Obama.”
