8:33 AM | From nuclear reactors to energy models
By Alan McDonald, IIASA Alumnus (1979-82 and 1997-2000) and member of the IIASA Alumni Advisory Board I stumbled on IIASA in 1975. I was 24 and working for General Electric’s Fast Breeder Reactor Department. I was supposed to figure out how safe General Electric should make its new breeder reactor, a type of nuclear reactor … Continue reading →
3:28 AM | What I learned this Earth Day, 2014
Laura Nielsen for Frontier Scientists – In the summer I drive to my favorite of many nearby glacial lakes, a deep down-turned gumdrop of cool water ringed in lillypads. I catch painted box turtles. After a frenetic chase and what feels like too long without air I surface gasping, and marveling at each turtle’s personality. They might battle hissing and clawing at air, or hide a bit before emerging to inspect me… or their own reflections in my goggles. Some... Read more
1:16 AM | Removal of crop residue for biofuels increases CO2 emissions
Back in 2007, Congress passed the US Energy Independence and Security Act, which was intended to be a mechanism towards removing our country’s dependence on petroleum and promote renewable energies.  The Senate opposed the original bill’s attempt to cut oil … Continue reading →

11:15 PM | Climate Change National Forum introduces the nonsense amplifier
The Climate Change National Forum now has a section called The Fact Checker. In it they will post the nonsense of pseudo-skeptics and they promise that the CCNF scientists will respond to it. I am glad not to be a CCNF scientist, having to jump up, drop everything I am working on, get myself into the topic and quickly write a response. Until that time, the nonsense is spread undisputed. And that happens every time the CCNF journalist think some pseudo-skeptical article is interesting. Poor […]

11:22 PM | The Moral Challenge of Dangerous Climate Change
The combination of a recently acquired desktop video magnifier and a kindle has for the time being restored some ease to my reading. Hence this review. I was drawn by the title The Moral Challenge of Dangerous Climate Change: Values, Poverty and Policy, since I can’t see the resistance to energy reform mounted by powerful […]

Any given time series, say July average temperature in the Moscow region since 1881, might exhibit both short-term (more brief) and long-term (more lasting) patterns of change. The longer-term is certainly something worth knowing about. It might be increasing, or … Continue reading →
8:58 AM | Global warming can't be blamed on CFCs – another one bites the dust
A paper published in the International Journal of Modern Physics B by the University of Waterloo's Qing-Bin Lu last year claimed that solar activity and human chlorofluorocarbon (CFC) emissions, not carbon emissions, could explain the observed global warming over the past century.  The journal has now published a rebuttal of that paper by Skeptical Science team members Dana Nuccitelli, Kevin Cowtan, Peter Jacobs, Mark Richardson, Robert Way, Anne-Marie Blackburn, Martin Stolpe, and […]

9:31 AM | Mitigating climate change – The IPCC WGIII report
What is the IPCC WG III? On 14th April 2014 the IPCC Working Group III (WG III) published their latest report (link) on climate change mitigation. This is the third of three reports from the IPCC, and follows on from their previous publications: WG I ‘The Physical Science Basis’, published in September 2013; and WG II ‘Impacts, Adaptation and Vulnerability’, published in March 2014.  Their latest report draws together over four years of work by over 230 scientists, […]

2:18 PM | Heartland logic: More people have heard of Fidel Castro than Michael Mann, therefore global warming is false.
This is a guest post from Narahani.   Or is happening and is good for you, or has stopped happening, or is caused by CO2 but only a little, or is about to reverse due to lots of yet-to-be-discovered negative feedbacks, and clouds. And anyhow, peas and water lilies love CO2 so ramping it up to 1000 ppm would be fantastic. The logic is dizzying.   And yes, Joe Bast repeated his widely criticized statement equating people who support action to limit climate change with […]
10:17 AM | Lip service: it’s all climate action ever gets from Key & Co
As expected, the New Zealand government’s response to the IPCC’s Working Group 3 report on mitigating climate change pays lip service to the science, while maintaining that NZ is doing all that can be expected. Climate change minister Tim Groser’s press release said that the IPCC report’s call for intentional cooperation meant that NZ is […]

Azara Mohammadi – To become a PhD candidate at the University of Alaska Fairbanks, Soumik Basu moved from his home in Kolkata, India to a region infamous for its “below zero” weather: Interior Alaska. Basu left warm weather and his family (not to mention his mother’s cooking) because “The climate is changing, so I wanted to study how these changes in the climate affect the storm activities over the Northern Hemisphere.” Specifically, Basu came to UAF to […]

6:01 AM | Climate contrarian backlash - a difficult lesson for scientific journals to learn
Scientific journals have had a bumpy road trying to learn how to deal with climate contrarians. Poor decisions by journal staff in dealing with contrarians have often led to editors resigning and a damaged reputation in the academic community. The latest such example is the journal Frontiers and its response to bullying by contrarians over a paper by Stephan Lewandowsky and colleagues. The paper analyzed the conspiratorial psychology of contrarian comments made on public blogs. As I previously […]

The IPCC has just released the summary for policymakers of the Working Group 3 report on mitigating climate change. It makes clear that the world has to act quickly to restrict carbon emissions to have a reasonable chance of restricting warming to 2ºC by the end of the century, but establishes that the costs of […]

The river Waal at Nijmegen, The Netherlands. The original river is to the right. The island has been created to give the river more space and reduce flooding.The New York Times Magazine has a beautiful article on a Dutch water manager, Henk Ovink.

The Dutch approach to water management is very different and looks […]
9:59 AM | Detailed regional data reduce warming-drought link doubts
In Portugal and Spain climate change has already driven over 2°C of warming in summer, and new findings from Sergio Vicente-Serrano from the Pyrenean Institute of Ecology are dispelling uncertainties that the temperatures are making drought more severe and widespread.

Vicente-Serrano, S., Lopez-Moreno, J., Beguería, S., Lorenzo-Lacruz, J., Sanchez-Lorenzo, A., García-Ruiz, J., Azorin-Molina, C., Morán-Tejeda, E., Revuelto, J., Trigo, R. & Coelho, F. (2014).
