Smaller Glaciers Boost Sea Level as Much as the Giants

Smaller Glaciers Boost Sea Level as Much as the Giants

As the planet warms under the influence of rising greenhouse gases, and melting ice drives sea level higher, scientists have focused mostly on changes in the vast ice sheets that cover Greenland and Antarctica. If either one melts substantially or slides into the ocean, the results would be catastrophic. But there’s another ice reserve to worry … Read More

As Oceans Warm, Fish Are Finding New ZIP Codes

As Oceans Warm, Fish Are Finding New ZIP Codes

The study, published Wednesday in the journal Nature, employs a novel index that creates a fish thermometer of sorts, teasing out evidence of population shifts from fishery catch records during the past four decades. The study is the first to detect climate change-related shifts in the range of fish species on a global scale. In doing so, it provid… Read More

Panel Finds Flaws with NWS Guidance on Sandy’s Surge

Panel Finds Flaws with NWS Guidance on Sandy’s Surge

The National Oceanic and Atmospheric Administration (NOAA) released its final review of the agency’s performance during Hurricane Sandy, finding that while the agency provided accurate forecasts of the storm’s path and strength well ahead of time, there were many shortcomings, including confusing and poorly timed guidance on the expected storm surg… Read More

Tinderbox-Dry Western U.S. at High Risk of Major Wildfires

The anticipated escalation in U.S. wildfire activity comes after the slowest start to wildfires in at least 10 years, according to Jeremy Sullens, a forecaster at NIFC. As of May 3, the country had seen 13,150 wildfires, which have burned about 153,000 acres. Due to a combination of drought and record heat, 2012 saw one of the most destructive wild… Read More

Warming Could Slash Species’ Habitat Ranges in Half

Warming Could Slash Species’ Habitat Ranges in Half

Vast numbers of plant and animal species could see their ranges slashed in half later this century as a result of climate change, according to a study in Nature Climate Change. The result, say the authors, could be serious ecosystem disruptions along with the loss of so-called “ecosystem services,” such as the purification of air and water; erosion… Read More

Amazon May Lose 65 Percent of Land Biomass by 2060

Amazon May Lose 65 Percent of Land Biomass by 2060

There will be no winners if agriculture made possible by widespread felling in the Amazon continues to expand, say researchers from Brazil and the U.S. They calculate that the large-scale expansion of agriculture at the expense of the forest could entail the loss of almost two-thirds of the Amazon’s terrestrial biomass by later this century … Read More
