2:20 PM | Arctic sea-ice decline erratic as expected
Imagine a ball bouncing down a bumpy hill. Gravity will ensure that the ball will head downwards. But, if the ball hits a bump at a certain angle it might move horizontally or even upwards for a time, before resuming its inevitable downward trajectory. This bouncing ball is an analogy for the behaviour of Arctic … Continue reading Arctic sea-ice decline erratic as expected →
6:35 AM | Climate researcher Bart Strengers wins wager with climate sceptic Hans Labohm
This is a re-post from My View on Climate Change Guest post by Bart Strengers. Originally appeared as a news item on the PBL website. Late 2009, in the run-up to the international climate conference in Copenhagen, PBL climate researcher Bart Strengers had an online discussion with climate sceptic Hans Labohm on the website of the Dutch news station NOS (in Dutch). This discussion, which was later also published as a PBL report, ended in a wager. Strengers wagered that the mean global […]

James Lawrence Powell is a former geology professor, college president and museum director. He is currently the executive director of the US National Physical Science Consortium. He is also an excellent communicator of science for the general reader.

10:00 AM | Stratospheric aerosol geoengineering and the polar vortex
Geoengineering by reducing the amount of solar radiation the Earth absorbs has become a hot topic in the last few years. Of all the impacts geoengineering might have on our climate, why on earth should we care about what goes … Continue reading →
6:23 AM | Climate change could impact the poor much more than previously thought
It’s widely accepted that climate change will have bigger negative impacts on poorer countries than wealthy ones. However, a new economic modeling study finds that the economic impacts on these poorer countries could be much larger than previous estimates. As a result, they suggest that we should be aiming to limit global warming to near, or perhaps even less than the international target of 2°C. This conclusion is in sharp contrast to current economic models, which generally conclude […]

8:35 PM | Will the ocean follow the land? Marine ecosystems at a tipping point to follow terrestrial defaunation

12:00 AM | We have a new record
The look of Gavin Schmidt accurately portrait my feelings for the Daily Mail.It seems the word record has a new meaning. 2014 was a record warm year for the global temperature datasets maintained by the Americans: NOAA, GISS and BEST, as well as for the Japanese dataset. For HadCRUT of the UK MetOffice is seems not to be clear which year will be highest.* The method of Cowtan and Way (C&W) is expected to see 2014 as the second warmest year. The method of C&W is currently seen as the […]

4:06 PM | Thoughts on 2014 and ongoing temperature trends
Last Friday, NASA GISS and NOAA NCDC had a press conference and jointly announced the end-of-year analysis for the 2014 global surface temperature anomaly which, in both analyses, came out top. As you may have noticed, this got much more press attention than their joint announcement in 2013 (which wasn’t a record year). In press […]
12:30 PM | Amateurs on climate
Amateurs are the people who do something for the love of it, without getting paid for it.  I get paid for doing what I love, so don't get to be called an amateur*.  One of my favorite amateurs on climate is Jan Schloerer.  He was active in the Usenet group Sci.environment in the 1990s, and wrote a number of articles on climate for nonprofessionals.  A number of excellent articles.  He ok'd my posting them to my personal web site (I used to be on and I'm now, […]
10:00 AM | The wrinkled retainer returns with a Peer-reviewed Peer
There is much ado at Tannochbrae Manor, because the Laird has once again disproved global warming. One equation is all it takes! And an article in a new Chinese science journal with some friends, and lo! Take away that inappropriate and misapplied equation, remove the unjustifiable tripling and the climate “crisis” vanishes. You couldn’t make […]
6:43 AM | The oceans are warming so fast, they keep breaking scientists' charts
Ocean heat content data to a depth of 2,000 meters, from NOAA. Wow, was this a bad year for those who deny the reality and the significance of human-induced climate change. Of course, there were the recent flurry of reports that 2014 surface temperatures had hit their hottest values ever recorded. The 2014 record was first called on this blog in December and the final results were reported as well, here. All of this happened in a year that the denialists told us would not be […]

6:30 AM | Matt Ridley wants to gamble the Earth’s future because he won’t learn from the past
Have you ever watched a zombie movie and wondered if the protagonists will grow physically tired from having to repeatedly kill zombies that inevitably rise once again from the dead? That’s how people often feel when confronted with climate change myths that were debunked years ago. These myths never seem to stay dead, inevitably being revived by climate contrarians no matter how conclusively and repeatedly they’ve been debunked. And so we have writer Matt Ridley once again […]

10:29 PM | Squirrels’ role in climate change puzzle
Alaska’s North Slope is home to Arctic ground squirrels. Near the Atigun River their interlaced burrow network takes advantage of sandy soil. The burrows are so interconnected and the entrances so myriad that the scientists working there to decode Arctic ground squirrel mysteries carry a map denoting burrow entrance numbers so they can be certain to always return squirrels to their home burrows. Arctic ground squirrel lifestyle Why so much interest? Arctic ground squirrels are the only […]

Battery electrode design has always required a menage-a-trois: an active material or catalyst, a conductive additive, and a polymer binder to keep everyone together.  Unfortunately, constructing batteries this way limits their energy density because it increases material mass and processing steps.  But a … Continue reading →

8:00 PM | Call to climate scientists: submit your quote for 97 Hours of Consensus 2015
On 7 September 2014, we launched 97 Hours of Consensus. Every hour for 97 consecutive hours, we published a cartoon of a climate scientist with a quote about climate change. We also published a very cool interactive webpage. Our purpose: to raise awareness of the scientific consensus on human-caused global warming. The series was an amazing success. We reached millions of people through social and mainstream media, including President Obama tweeting about 97 hours to […]
7:36 PM | Martin Luther King Jr. Day
I share the Reverend Dr. Martin Luther King Jr.'s dream.  Among other things, for people to be judged by the content of their character rather than the color of their skin.  It is an ideal.  Since that dream has still not been achieved more than 50 years after he gave the speech, it's apparently a challenging ideal.  Given events of the last few years, I'm not confident that we're closer to it than we were 20 years ago.  Maybe I was just that naive 20 years ago, maybe I […]

12:09 AM | Heat: 2014 breaks global temperature records, 2015 could be hotter
Last year was the warmest year on record for the planet, analyses by NASA and NOAA show, and it’s possible that 2015 could be warmer still. 2014 was warmer than previous record holders 2005 and 2010, and comfortably ahead of 1998. 13 of the hottest 15 years on record have all occurred since 2000. Remarkably, […]
