11:44 PM | Climate change roundup: Underestimated ocean heat content and emissions from the peatlands!
A couple articles caught my attention over the past week that give some new modeling information about global warming.  So…I thought I’d do a quick rundown of the major findings of each! Why hold me at that gate of your secret? … Continue reading →

10:51 AM | Climate response estimates from Lewis & Curry
Guest commentary from Richard Millar (U. Oxford) The recent study of climate sensitivity estimated from the transient surface temperature record is being lauded as something of a game-changer – but how much of a game-changer is it really? The method at the heart of the new study is essentially identical to that used in the […]

10:39 AM | This Changes Everything
Naomi Klein’s new book, This Changes Everything: Capitalism vs. the Climate places the battle against climate change firmly in the context of the struggle for social justice. Fighting climate change means reordering the ways our economies are structured. The pillars of the reigning economic paradigm – aprivatisation, deregulation and lower taxation paid for by cuts […]

5:37 AM | Tackling global warming will improve health, save lives, and save money
A very recent study released in JAMA (Climate Change: Challenges and Opportunities for Global Health) provides a very thorough review showing how climate change affects human health. Perhaps more importantly, the paper also describes how tackling climate change leads to many health and economic benefits. Authors Jonathan Patz, Howard Frumkin and colleagues combined a survey of the current literature with measured and projected changes to climate to assess health risks associated with climate […]

4:26 PM | Grayling and the great commute
I remember vivid visuals which manage to compress something immense into the space of seconds: the cosmic force of a big bang flinging matter across the universe, Ice Age glaciers clamoring down from the north then retreating again, time-lapse footage of the tides' rhythmic breathing. Even commuters dancing the stop-and-go of a traffic light. An Arctic grayling (Thymallus arcticus) is a fish; it's also a commuter of sorts. Its entire life is a rhythm of motion undertaken to survive and... Read […]

9:23 AM | There’s nothing quite like renewables: Natural gas production will not reduce future greenhouse gas emissions as hoped
Originally posted on Goodnight Earth:Appropriate and useful climate policy-making requires accurate and reliable data about the future.  Nowhere is this more important than when setting carbon emission standards and projecting percentages of each energy source to match energy needs (coal, natural gas, nuclear, renewables, etc.).  But projecting how emissions will change in the decades to…

5:51 AM | Scientists find human fingerprints all over Australia's hottest year on record
Australia had a hot one in 2013 – a real record breaker. We started off with a heat wave that made January 2013 the hottest month on record that was part of the hottest summer on record that then became the hottest year on record. Meteorologists and climatologists looking at records tend to express things by “anomalies” – how far above or below the long-term average is a particular temperature. September 2013 had all the anomalous bells and whistles you could muster, […]

5:29 AM | Global warming: a battle for evangelical Christian hearts and minds
The Cornwall Alliance for the Stewardship of Creation is a conservative evangelical Christian public policy group that promotes a free-market approach to protecting the environment. The organization recently published a list of ten reasons it opposes policies to reduce carbon pollution and slow global warming, purportedly to protect the poor. As the first point on the list illustrates, the group essentially believes that the Earth’s climate will be able to correct any damage done by […]

5:27 PM | Limiting global warming to 2 °C – why Victor and Kennel are wrong
In a comment in Nature titled Ditch the 2 °C warming goal, political scientist David Victor and retired astrophysicist Charles Kennel advocate just that. But their arguments don’t hold water. It is clear that the opinion article by Victor & Kennel is meant to be provocative. But even when making allowances for that, the arguments […]

12:21 PM | New and Improved Ice Loss Estimates for Polar Ice Sheets
In a previous post, several years ago, I discussed the various ways that we measure changes in the Antarctic and Greenland ice sheets. Today, scientists still use these main methods for identifying ice changes but recent technological and data processing advances have improved the accuracy of these estimates. An example of this is the CryoSAT-2 satellite system which was launched 4 years ago by the European Space Agency and is now giving early results on the state of the two polar ice sheets. […]

The latest climate extremes report finds that 9 out of 16 extreme weather events from last year were influenced by climate change. In particular, the conditions that led to New Zealand’s severe North Island drought — the worst for 41 years, estimated to have cost the economy NZ$1.3 billion — were made more likely by […]

6:25 AM | How did the UK grid respond to losing a few nuclear reactors?
This is a re-post from PassiiviIdentiteetti, written by Jani-Petri Martikainen. Answer: mainly by increasing the use of coal in power production. In the second week of August power company EDF decided to shutdown their reactors in Heysham and Hartlepool. This was a precautionary measure after finding a defect in the boiler of Heysham unit 1. In total 4 reactors that can produce up to 2.6 GigaWatts (GW) of electricity were turned off. On the week they were turned off, the UK used an […]

11:30 AM | Multiple Working Hypotheses
In exploring Arctic ice minima I was not so much trying to reach conclusions as to find hypotheses for further testing and exploration.  Let's pick up the hypotheses side now, as I think it gets much too little attention in science education and science student practice.  In saying that, I'm projecting my bias, of course.Part of that bias comes from having read and agreed with T. C. Chamberlin's Method of Multiple Hypotheses (1890).  Or at least liked my take on it.  It also […]
