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
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
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
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
Meet GROVER: NASA’s New Ice-Loving, Roving Robot
The GROVER will initially be operated by scientists at the National Science Foundation’s Summit Camp, where the ice sheet is about 2-miles thick, according to a NASA press release. The robot will be capable of operating at all hours during the 24-hour sunlight that characterizes the Arctic summer.… Read More
Global CO2 Levels Set to Pass 400 ppm Milestone
The concentration of carbon dioxide in the atmosphere has reached 399.72 parts per million (ppm) and is likely to pass the symbolically important 400ppm level for the first time in the next few days. Readings at the U.S. government's Earth Systems Research laboratory in Hawaii, are not expected to reach their 2013 peak until mid May, but were … Read More
IMF Rejects Fossil Fuel Subsidies, Calls for Reform
Fossil fuel subsidies provided by both rich and poor countries to keep their citizens happy are holding back the world economy, accelerating climate change and damaging the health of current and future generations, according to the International Monetary Fund. The worst offender of all is the United States, which allows annual subsidies of $502 … Read More
Scientists Raise Questions on Drought and Climate
When the National Oceanic and Atmospheric Administration issued a report on April 11 that seemed to exonerate global warming as a cause of last summer’s historic drought, a reasonable person might conclude that global warming had been exonerated. After all, NOAA is a highly respected organization, and the report’s lead author, meteorologist Martin … Read More
