Study: 97 percent Agreement on Manmade Global Warming
The research, which is the most comprehensive analysis of climate research to date, finds that 97.1 percent of the studies published between 1991 to 2011 that expressed a position on manmade climate change agreed that it was happening, and that it was due to human activity. The study looked at peer reviewed research that mentioned climate change … Read More
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
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
Warming Temps Cause Trees to Limit Warming—a Little
Trees may provide the Earth with a little shade from global warming – indirectly. European and Canadian researchers report that they have found what engineers like to call a negative feedback loop above the forests of Europe and North America. It works like this. Trees – those natural chemical factories that routinely deliver complex aromatic compo… Read More
Carbon Dioxide Passes 400 PPM Milestone, NOAA Finds
Climate scientists recognize this 400 ppm mark as a symbolic milestone, illustrating the rapid increase of human-caused CO2 emissions over the past century. Numerous other climate data, gleaned from ice cores, ocean sediment, and other sources show that this is the highest CO2 concentration in the air in all of modern human history, possibly as far… Read More
Greenland’s Ice Loss May Slow, But Coasts Still At Risk
The flow of Greenland’s glaciers toward the sea may have increased significantly in the past decade, but a new report in Nature finds that rate of increase is unlikely to continue. “The loss of ice has doubled in the past 10 years, but it’s not going to double again,” said lead author Faezeh Nick, a glaciologist at the University Centre in Svalbard… Read More

The Last Time CO2 Was This High, Humans Didn’t Exist
The news that CO2 is near 400 ppm for the first time highlights a question that scientists have been investigating using a variety of methods: when was the last time that CO2 levels were this high, and what was the climate like back then?… Read More
