Arctic Sea Ice Retreat: When Will the Arctic Ocean be Ice-Free During Summer?
Researchers have long recognized the Arctic as a region that shows early and amplified signals of anthropogenically-driven global climate change (e.g., IPCC 2001; Technical Basis, p. 807). Among the most dramatic and most widely watched changes in this region each summer is the retreat of the Arctic sea ice extent. Since it first became possible…

Wally Broecker wins prestigious BBVA Foundation award for Climate Research
Earlier today it was announced that Wallace S. Broecker, Newberry Professor of Earth and Environmental Sciences at Columbia University, has received the BBVA Foundation Frontiers of Knowledge Award in Climate Change Research. In announcing the award, the jury cited Wally for his seminal research on ocean chemistry and for pioneering the development of Earth System…

Prescriptive science?
This is just a short post to draw your attention to John Tierney’s New York Times column on John Holdren’s appointment as Obama’s science advisor. Tierney contends that: “Dr. Holdren is certainly entitled to his views, but what concerns me is his tendency to conflate the science of climate change with prescriptions to cut greenhouse…

Cooler, 2008 Still Ranks in the Top 10
A paper released last week by the World Meteorological Organization reports that the preliminary global mean temperature for 2008 is 14.3°C (57.7° F). This is significantly below 2007’s 14.7°C (58.5°F), and – as Time magazine reports – the coolest year since the turn of the century. Sadly, our half-hearted efforts at carbon offsetting cannot take…

Climate change and the hydrological cycle
The prospects of significant and damaging changes in the hydrological cycle due to the increase in atmospheric greenhouse gas concentrations were raised in earlier IPCC reports and restated more strongly in the most recent, 2007 Fourth Assessment Report (AR4). Now, the U.S. Climate Change Science Program (CCSP) issued its final Synthesis and Assessment Report on…

Abrupt Climate Change, How Likely?
Yesterday the USGS released “Abrupt Climate Change, Final Report, Synthesis and Assessment Product 3.4” of the U.S. Climate Change Science Program and the Subcommittee on Global Change Research. You can download the four page brochure or the full report here. Columbia scientists Edward R. Cook (the lead author) and Richard Seager, both from Lamont-Doherty Earth…
