Past hurricane counts accurate
Dr. Michael Mann and his student Thomas Sabbatelli have examined the hurricane and tropical storm counts back to 1870 and determined that the counts are largely reliable, disputing earlier claims that the counts may be underestimating by as much as 3 storms per year. This research is presented in a paper published in Geophysical Research Letters. Image Credit: UW/CIMSS

Volcanoes key to Earth's oxygen atmosphere
The transition of Earth's atmosphere from oxygen-poor to oxygen-rich was caused by a switch from underwater volcanoes to a mix of underwater and terrestrial volcanoes. Using biomarkers in rocks dating back to the Archaean and the Palaeoproterozoic eras, Dr. Lee Kump and his colleagues linked the submarine and terrestrial volcanic record to the levels of oxygen.

Emissions targets hot topic at climate conference
Delegates at May's climate change conference in Bangkok, Thailand, debated the controversial issue of emissions caps. The final report argued that greenhouse gas levels must be stabilized by 2015 in order to limit the amount of global warming. Dr. Michael Mann comments on the 450 ppm threshold.
Why Files: Melting ice, rising seas, is anybody ready?
The Why Files presents comprehensive look at the issue of melting ice sheets and glaciers and the possible impact on global sea level and low-lying coastal areas. Dr. Richard Alley explains that there is a great deal of uncertainty on how much sea level rise we can expect to see from global warming. He also delineates the type of research needed to better quantify the response of ice sheets to climate change.
More Forecasts of an Active Atlantic Hurricane Season
Science blogger Chris Mooney reports on predictions of another active hurricane season in the North Atlantic. He also points to an upcoming paper in the Journal of Geophysical Research-Atmospheres from Mr. Thomas Sabbatelli and Dr. Michael Mann on a new tropical forecasting method which takes into account both sea surface temperatures (SSTs) and the state of the El Nino-Southern Oscillation (ENSO).
A Convenient Untruth
Vanity Fair's "Green Issue" for May 2007 features this article where various scientists and experts, including Dr. Michael Mann, respond to comments from climate change skeptics. Dr. Mann responds to various criticisms surrounding the "hockey-stick" graph of temperatures over the past millennia. The ESSC is also mentioned as a resource for this "Green Issue."
Conservative Climate: Consensus document may understate the climate change problem
The recent report from the Intergovernmental Panel on Climate Change (IPCC) may underestimate the effects of climate change, according to experts interviewed in this article in Scientific American. Dr. Richard Alley discusses the complexities of trying to quantify effects such as the melting of Greenland's ice sheet in climate models.
Is Earth near its 'tipping points' from global warming?
USA Today reports on potentially devastating impacts of climate change on the planet based on the recent report from the Intergovernmental Panel on Climate Change (IPCC). Dr. Michael Mann cautions that the report's conclusions may be a bit conservative, since it lacks input from groundbreaking research from the last several months.
Markowski receives 5-Year NSF Career Award
Dr. Paul M. Markowski, Assistant Professor of Meteorology, recently received a 5-year NSF Career Award. The title of the project is "A Study of the Radiative Effects of Cloud Shadows on the Dynamics of Long-Lived Convective Storm." The project will study how thunderstorms are affected by large regions of cool ground temperatures produced through the "cloud-shading" effect of the storms themselves. An NSF Career Award is a highly selective grant given to new faculty members believed to be the next generation of academic leaders.
