'Ozone hole' may be a warming factor due to wind shifts

First, a clarification; while the AGU calls it an “ozone hole”, it technically isn’t. As NASA says here, it really isn’t a “hole” in the true sense of the word, it is simply a region of reduced O3 concentration that periodically changes in size, shape, and density.  -Anthony Ozone hole might slightly warm planet AGU…

Flu forecasts using weather, not climate

Flu outbreaks predicted with weather forecast techniques BOULDER—Scientists at Columbia University and the National Center for Atmospheric Research have adapted techniques used in modern weather prediction to generate local forecasts of seasonal influenza outbreaks. By predicting the timing and severity of the outbreaks, this pilot system can eventually help health officials and the general public…

Glaciergate post script – they'll shrink anyway

From Brigham Young University and the “IPCC, take your 2035 and shove it” department comes this study: Himalayan glaciers will shrink even if temperatures hold steady Come rain or shine, or even snow, some glaciers of the Himalayas will continue shrinking for many years to come. The forecast by Brigham Young University geology professor Summer…

'Counterintuitive finding suggests that unexpected factors may govern a glacier's response to climate change'

From the University at Buffalo, new evidence that large ice sheets can grow/disappear quickly on decadal scales in response to regional temperature changes. A descriptive video follows. How fast can ice sheets respond to climate change? Scientists report that prehistoric glaciers reacted rapidly to a brief cold snap, providing a rare glimpse of glaciers’ response…
