“BEST” Researchers’ efforts aim to improve data on surface temperature estimates and their use could bolster public’s understanding of global land temperatures. It’s no surprise that the effort is not without some controversy.

Climate models are a “foundation” of climate understanding … and also a “lightning rod” in the climate debate. So where is the coverage of models in mainstream news outlets? In some of the most prominent sources, it’s in opinion, and [...]

“Rebound” effect and “backfire” are big on certain journalism blogs these days, but reporters should take heed in not over-doing the current buzz on the reverse effects of energy efficiency measures.

All five of the major temperature indices — NASA’s GISTemp, National Climate Data Center (NCDC), Hadley Centre/UAE (HadCRUT3v), University of Alabama Huntsville (UAH), and Remote Sensing Systems (RSS) — have published their estimates of 2010 global surface or close-to-surface temperatures.

Understanding the carbon cycle is a key part of understanding the broader climate change issue. But a number of misconceptions floating around the blogosphere confuse basic concepts to argue that climate change is irrelevant because of the short residence time [...]

Critics often complain that the three major surface temperature records — NASA’s GISTemp, the University of East Anglia’s HadCRUT, and NOAA’s National Climate Data Center record — all rely on most of the same underlying station data, provided through the [...]

In the aftermath of the recent hacked e-mails affair, much opprobrium has been cast in the direction of the Climate Research Unit (CRU) at the University of East Anglia. In part the result of confusion over the meaning of the [...]
