9:29 AM | The UK winter of 2014-15: another Tabloid FAIL
Above: Express, October 10th 2014 Introduction: the first ominous signs “Winter 2014 set to be 'coldest for century' Britain faces ARCTIC FREEZE in just weeks”. That was the Daily Express headline on October 10th 2014. Quoting self-styled "independent" long-range weather forecaster James Madden, it warned of an icy apocalypse on the way: “A number of potentially very cold periods of weather and major snow events are likely to develop throughout this winter across large […]
8:40 AM | Extreme UK heatwaves
The largest impacts of increases in temperature will not be experienced due to changes in the mean, but by changes in the extremes. This is illustrated using UK heatwaves to show that the number of days which will require preventative action will increase by roughly a factor of 6 for a 2ºC increase in summer … Continue reading Extreme UK heatwaves →

3:07 PM | How to pick cherries
The not-so fine art of contriving to support the conclusion you predetermined is cherry picking.  Really not a good thing for a scientist to do or condone, but pretty common in politics.  The latest example comes from politician (now presidential candidate) Ted Cruz, being condoned/defended (even praised) by scientist Judy Curry. Suppose you're interested in global warming, just in understanding what's going on -- not in 'proving' that there is warming, or cooling, or that […]
7:46 AM | Leyland and Carter: the rebuttal that isn’t and the hypocrisy that is
Sciblogs editor Peter Griffin recently gave climate denial activists Bryan Leyland and Bob Carter a “right of reply” to my post pointing out the errors and inconsistencies in a Dominion Post op-ed penned by the pair. Griffin took this action because of vociferous complaints from Leyland, who took offence at my discussion of his expertise […]
5:34 AM | One satellite data set is underestimating global warming
A very important study was just published in the Journal of Climate a few days ago. This paper, in my mind, makes a major step toward reconciling differences in satellite temperature records of the mid-troposphere region. As before, it is found that the scientists (and politicians) who have cast doubt on global warming in the past are shown to be outliers because of bias in their results. The publication, authored by Stephen Po-Chedley and colleagues from the University of Washington, discusses […]

10:46 PM | The cool car: electric vehicles show possible benefit to combat global warming
Electric vehicles have been touted as a revolution waiting to happen to our transportation grid, just as soon as we can make a battery that provides long-range travel between charging stops.  They are also sold as a way to avoid … Continue reading →

6:48 PM | Tea water in Arctic rivers– carbon pathways
At the turn of the season as snow and ice melt, Alaska's waterways open up. "This is the highest this river will be this season," Jason Dobkowski said. "Here is this giant flush of particulate and nutrients that flow through the river. So we are trying to make sure we sample at this big flush period at the beginning of the season." Water he collects from the Sagavanirktok River on the North slope of Alaska teaches us more about how... Read more
5:47 PM | Are you practicing safe science?
Five weeks ago, I sliced through both tendons in left pinky. I was just about to start working in the lab, training my PhD student on the initial processing of a peat column from our Falkland Islands trip in December. We had bought a large serrated kitchen knife specifically to slice through 1 ft-square […]

Here is a quick video I made outlining the well-known “total dissolved inorganic carbon” (TDIC) procedure for measuring Net Ecosystem Productivity.  It is a very basic aide-memoir for undergraduate and postgraduate students […]
12:07 PM | Stupid is as Ted Cruz does
Ted Cruz denies that global warming is even happening. Appearing on “Late Night with Seth Meyers,” Cruz had this to say: Many of the alarmists on global warming, they’ve got a problem because the science doesn’t back them up. In … Continue reading →

Are you fed up with boring graphs? What about listening to your data instead of starring at them for hours? It is possible thanks to the sonification of data. Above, an example of the sonification played by physicists of CERN … Continue reading →
4:06 PM | What’s going on in the North Atlantic?
The North Atlantic between Newfoundland and Ireland is practically the only region of the world that has defied global warming and even cooled. Last winter there even was the coldest on record – while globally it was the hottest on record. Our recent study (Rahmstorf et al. 2015) attributes this to a weakening of the […]

3:58 PM | Climate Sensitivity Week
Some of you will be aware that there is a workshop on Climate Sensitivity this week at Schloss Ringberg in southern Germany. The topics to be covered include how sensitivity is defined (and whether it is even meaningful (Spoiler, yes it is)), what it means, how it can be constrained, what the different flavours signify […]

SkS Highlights John Mason's The cause of the greatest mass-extinctions of all? Pollution (Part 1 and Part 2) generated a lively discussion among readers and attracted the most comments of the articles posted on SkS during the past week.  El Niño Watch NOAA's Climate Prediction Center is saying that there is an approximately 50-60% chance that El Niño conditions will continue through Northern Hemisphere summer 2015. This outlook was issued before the recent […]
