A second strategically-timed unauthorized release of climate scientists’ e-mails dating from 2009 apparently seeks to disrupt international climate negotiations in Durban, South Africa. But the newly released materials, while not always flattering to authors or participants, shed little light on [...]

‘BEST’ researchers release not-yet-peer-reviewed findings supporting validity of temperature station records and rejecting urban heat island arguments. Climate ‘skeptics,’ having anticipated good news, cry foul … and climatologists long supportive of the evidence wonder, ‘So? What’s New?’

There’s a lesson to be learned from an editor’s having resigned over his journal’s publication of a research report thought to have been inadequately reviewed: extraordinary claims must be supported by extraordinary evidence. Headline writers and media … take note.

A recent analysis concluding that natural gas from shale poses more climate change problems than combustion of coal rests heavily on a problematic time frame. In the end, the widely reported article may do more to muddle understanding of natural [...]

“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.

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 [...]
