Real Climate

  • Plugging the leaks - Guest commentary by Beate Liepert, NWRA Clouds and water vapor accounts for only a tiny fraction of all water on Earth, but in spite of it, this moisture in the atmosphere is crucially important to replenishing drinking water reservoirs, crop yields, distribution of vegetation zones, and so on. This is the case because in the [...]
  • Greenland Glaciers — not so fast! - There have been several recent papers on ice sheets and sea level that have gotten a bit of press of the journalistic whiplash variety (“The ice is melting faster than we thought!” “No, its not!”). As usual the papers themselves are much better than the press about them, and the results less confusing. They add [...]
  • Yamalian yawns - Steve McIntyre is free to do any analysis he wants on any data he can find. But when he ladles his work with unjustified and false accusations of misconduct and deception, he demeans both himself and his contributions. The idea that scientists should be bullied into doing analyses McIntyre wants and delivering the results to [...]
  • The legend of the Titanic - It’s 100 years since the Titanic sank in the North Atlantic, and it’s still remembered today. It was one of those landmark events that make a deep impression on people. It also fits a pattern of how we respond to different conditions, according to a recent book about the impact of environmental science on the [...]
  • Unforced variations: May 2012 - New open thread for this month: misrepresentations of wind farm impacts on local climate? Clouds and contrarians? or whatever…
  • Unlocking the secrets to ending an Ice Age - Guest Commentary by Chris Colose, SUNY Albany It has long been known that characteristics of the Earth’s orbit (its eccentricity, the degree to which it is tilted, and its “wobble”) are slightly altered on timescales of tens to hundreds of thousands of years. Such variations, collectively known as Milankovitch cycles, conspire to pace the timing [...]
  • Another well-deserved honor: Oeschger medal awarded to Michael Mann - As many will have already heard, our colleague, RC co-founder and friend Michael Mann will receive the Oeschger medal from the European Geosciences Union this week in Vienna. We are delighted to announce this and to congratulate Mike. Hans Oeschger was a Swiss scientist originally trained as a nuclear physicist. His name is well known [...]
  • HadCRUT4 data now available - Just a quick note to point out that the HadCRUT4 data are now fully available for download. Feel free to discuss (or point to) any analyses you’d like to see done in the comments, and perhaps we’ll update this post with the more interesting ones.
  • Arctic Sea Ice Volume: PIOMAS, Prediction, and the Perils of Extrapolation - Guest Commentary by Axel Schweiger, Ron Lindsay, and Cecilia Bitz We have just passed the annual maximum in Arctic sea ice extent which always occurs sometime in March. Within a month we will reach the annual maximum in Arctic sea ice volume. After that, the sea ice will begin its course towards its annual minimum [...]
  • Evaluating a 1981 temperature projection - Guest commentary from Geert Jan van Oldenborgh and Rein Haarsma, KNMI Sometimes it helps to take a step back from the everyday pressures of research (falling ill helps). It was in this way we stumbled across (pdf). In 1981 the first author of this post was in his first year at university and the other [...]

Climate Skeptic

  • Burning Down the House - Steve Zwick walked back his comments about letting skeptics’s houses burn down and tries to clarify the point he was trying to make.  I have further comments in a new Forbes article here.  An excerpt: Steve Zwick has posted an update to the post I wrote about last week and has decided the house-burning analogy was [...]
  • A Vivid Reminder of How The Climate Debate is Broken - My Forbes column is up this week.  I really did not want to write about climate, but when Forbes conctributor Steve Zwick wrote this, I had to respond We know who the active denialists are – not the people who buy the lies, mind you, but the people who create the lies.  Let’s start keeping track [...]
  • Updated Charts - These are some updated charts I need for linking from a Forbes article.  Look for the link coming soon.
  • Server Issues - I upgraded my server account – we will see if that gets us past the server issues the site has been experiencing over the last few days.
  • Tilting at Straw Men - In my Forbes article a few weeks ago, I showed how the arguments alarmists most frequently use to “prove” that skeptics are wrong are actually straw men.  Alarmists want to fight the war over whether the greenhouse gas effect of CO2 is true and whether the world has seen warming over the last century, both [...]
  • The Alarmist Bait and Switch - This quote from Michael Mann is a great example of two common rhetorical tactics of climate alarmists: And so I think we have to get away from this idea that in matters of science, it’s, you know, that we should treat discussions of climate change as if there are two equal sides, like we often do in [...]
  • Revising History - This is a topic we have covered here a lot – downward revisions to temperatures decades ago that increase the apparent 20th century warming.  Here is a great example of this from the GISS for Reykjavik, Iceland.  The GISS has revised downwards early 20th century temperatures by as much as 2C, despite Iceland’s Met office crying [...]
  • Who Wrote the Fake Heartland Strategy Memo? - Certainly Peter Gleick is still in the running. But as I wrote in Forbes last week, the memo does not have the feel of having been written by a “player” like Gleick.  It feels like someone younger, someone more likely to take the cynical political knife-fighting statements of someone like Glieck (e.g. skeptics are anti-science) [...]
  • Peter Gleick Admits to Stealing Heartland Documents - I have an updated article at Forbes.  A small excerpt In a written statement, Peter Gleick of the Pacific Institute, and vocal advocate of catastrophic man-made global warming theory, has admitted to obtaining certain Heartland Institute internal documents under false premises, and then forwarding these documents to bloggers who were eager to publish them. Gleick (also [...]
  • Heartland Documents: Whose Biases are Being Revealed Here? - I could not resist commenting on the brouhaha around the stolen Heartland Institute documents in my column at Forbes.  The key one that is the “smoking gun” now appears to be fake.  I wrote in part: One reason I am fairly certain the document is fake is this line from the supposed skeptic strategy document: His [...]
