Why Cutting CO2 with Renewables Alone Means Betting Big on Efficiency: Behind the IPCC's Climate Stabilization Scenarios

December 9, 2014 by Suzanne Waldman

Nuclear Energy and IPCC Climate Models

What is the problem with leaning on renewable energy as a solution to the consequences of climate change? All-RE scenarios show one thing in particular, which is they all depend on increasingly intensive demand reductions over time to avert climate change.[read more]

Energy Quote of the Day: 'Alaska is Going to be the Next Florida'

September 27, 2014 by Jared Anderson

Alaska and Environmental Risk

There is widespread agreement that carbon emissions have significantly increased since the industrial revolution and these emissions are playing a climate-changing role, but the consensus diverges when modeling future climate change effect scenarios.[read more]

Research Suggests Climate Models Underestimate Climate Sensitivity

August 15, 2014 by Tom Schueneman

Climate Models and Risk

Climate models are mathematical representation of an enormously complex system. They are intended to project trends, not predict events. They are an imperfect but indispensable tool to gain an understanding of what we can likely expect in the future.[read more]

The Economist and the Missing Warming: A Dangerous Trap

August 24, 2013 by Niall Enright

Climate Change and the Economist

The Economist has an interesting blog on the subject of the recent slower-than-expected rises in global temps compared to climate model predictions. Climate scientists are put on the back foot to explain the “missing warming” and so have fallen into a dangerous trap.[read more]

Dangerously optimistic computer models

February 24, 2011 by Lou Grinzo

I’d guess that most people here have seen the warnings that much of the computer modeling and other science done related to climate is slightly to very conservative. Not in the political sense, but in terms of not leaping to conclusions.[1] I’ve made the case repeatedly that this is a good thing, even in our current situation. The...[read more]

An Interesting Gripe

November 24, 2009 by Michael Tobis

Never one to shy away from sticking his neck out, Ray Pierrehumbert (aka Raypierre) has actually submitted a top level article to Dot Earth. Ray's follow-up comment is especially interesting.There is so much uninformed comment here I don't know where to begin. So many people are complaining about the "open-ness" of climate modelling,...[read more]

UK Met Office: Catastrophic climate change, 13-18 °F over most of U.S. and 27 °F in the Arctic, could happen within 50 years, but “we do have time to stop it if we cut greenhouse gas emissions soon.”

September 28, 2009 by Joseph Romm

Finally, some of the top climate modelers in the world have done a “plausible worst case scenario,” as Dr Richard Betts, Head of Climate Impacts at the Met Office Hadley Centre, put it today in a terrific and terrifying talk (audio here). No, I’m not taking about a simple analysis of what happens if the nation and the world just keep on...[read more]

The path of Tropical Storm Danny

August 28, 2009 by Simon Donner

I'll have more on what we should be saying about climate change shortly (there are couple interesting responses at the Energy Collective cross-post) .The model projections at right show that fourth named tropical storm of the Atlantic season is expected to take a path quite similar to that of Bill, interesting given how El Nino events...[read more]
