6:50 AM | What's the role of the deep ocean in global warming? Climate contrarians get this wrong
This is a re-post from Greg Laden's Blog What is the role of the ocean’s abyss in global warming?1 I’ve already posted on a study published in Nature Climate change that shows that the amount of extra global warming related heat in the Southern Oceans is greater than previously thought. There is another paper in the same journal by Llovel et al, “Deep-ocean contribution to sea level and energy budget not detectable over the past decade.” This paper verifies previous […]

9:51 AM | The long hot tail of global warming - new thinking on the Eocene greenhouse climate
Past climate changes like the Eocene Hyperthermals left many traces in the geological record. These tell scientists a great deal about what the Earth looked like in these hothouse eras, the changes they made to rainfall, drought, landscape, oceans, ecosystems and life. Ultimately those records contain clues to the causes of the climate changes, and are signposts to the effects we can expect from modern climate change. A trio of new studies show that the Eocene Hyperthermals were the result of, […]

5:42 AM | GWPF funder Lord Leach – relying on unreliable sources of global warming information
DeSmog UK has found that libertarian banker Lord Leach is a likely funder of the anti-climate political advocacy group Global Warming Policy Foundation (GWPF). In May of 2009, Lord Leach gave a long speech in Parliament detailing his beliefs about global warming. The speech was full of inaccuracies, myths, and misinformation. Known as a Gish Gallop, the sheer number of false claims in the speech would require tremendous effort to debunk. Most telling were the sources that Lord Leach relied upon […]

Guest commentary from Richard Millar (U.

The method at the heart of the new study is essentially identical to that used in the […]

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.

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 […]

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, […]

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 […]
