About 10 years ago, December 20, 2002 to be exact, we published a paper titled “Revised 21st century temperature projections” in the journal Climate Research. We concluded: Temperature projections for the 21st century made in the Third Assessment Report (TAR) of the United Nations Intergovernmental Panel on Climate Change (IPCC) indicate a rise of [...]

Our headline is taken from New York Times blogger Andy Revkin’s recent DotEarth post covering the results of a new paper which investigates the relationship between higher temperatures in recent decades and methane release from the Arctic seabed off the Siberian coast. As you can probably tell from the headline, the research team, led [...]

A few weeks ago, we ran a story about a paper which was (then) soon to be published in Science magazine which generally concluded that the earth’s climate sensitivity (how much the earth’s average temperature will rise from a doubling of the atmospheric carbon dioxide concentration) was likely lower than the IPCC’s best guess [...]

There is word circulating that a paper soon to appear in Science magazine concludes that the climate sensitivity—how much the earth’s average temperature will rise as a result of a doubling of the atmospheric concentration of carbon dioxide—likely (that is, with a 66% probability) lies in the range 1.7°C to 2.6°C, with a median value [...]

The last couple of winters across the central and eastern United States as well as much of Europe were on the cold and snowy-side of things, to say the least. And of course, anytime there is some type of weather misery, a particular segment of the population likes to trot out global warming as the [...]

In our last World Climate Report article, we detailed a recent paper that showed that climate models which fail to account for the evolution of stratospheric aerosols (that is, reflective particles in the earth’s upper atmospheric) during the past decade or two project less warming than they would have had they included the influence of [...]

Over at the Cato Institute website, WCR’s Patrick Michaels has another one of his informative Current Wisdom pieces, a place where he “reviews interesting items on global warming in the scientific literature that may not have received the media attention that they deserved, or have been misinterpreted in the popular press.” The topic this time [...]

We occasionally highlight articles from the scientific literature showing that the cooling impact of aerosol emissions from human activities has been overestimated. Such findings are important because they mean that warming from greenhouse gases has been similarly overestimated. Climate models rely on aerosol cooling to keep warming in check—otherwise they predict far more warming [...]

A few weeks back, in our article Biggest Drop in U.S. Greenhouse Gas Emissions, we promised to take a look at the implications of a new study that calculated the impact on the earth’s greenhouse effect from the extraction and use of natural gas produced from deep underground shale beds (through a process known as [...]

In 2009, greenhouse gas emissions in the U.S. experienced their biggest drop since the U.S. Energy Information Administration began tracking them during the 1990-2009 timeframe. The EIA’s latest numbers on greenhouse gas emissions can be found in their just released report “Emissions of Greenhouse Gases in the United States 2009.” The EIA starts out with [...]
