The white, reflective barrier protecting our northern polar region from the heat-amplifying effects of human-caused warming took a severe blow today. The National Snow and Ice Data Center’s sea ice area measure essentially fell off a cliff as values plummeted by more than 286,000 square kilometers. That’s an area of ice the size of Nevada lost in a single 24 hour period. A state-sized region flipping from white, reflective, cooling ice, to dark, heat-absorptive water.
Geneva, 26 May 2014 (WMO) - For the first time, monthly concentrations of carbon dioxide (CO2) in the atmosphere topped 400 parts per million (ppm) in April throughout the northern hemisphere. This threshold is of symbolic and scientific significance and reinforces evidence that the burning of fossil fuels and other human activities are responsible for the continuing increase in heat-trapping greenhouse gases warming our planet.
The accelerating rate of climate change poses a severe risk to national security and acts as a catalyst for global political conflict, a report published Tuesday by a leading government-funded military research organization concluded.
It is often claimed by those who deny the reality of climate change that scientific forecasts about the impact of global warming are far too uncertain to merit taking action. There is no reason to suffer the inconvenience of leaving the planet's fossil fuels unburned when the current analyses of meteorologists, oceanographers and geophysicists will probably turn out to be false alarms, they argue. Such contention is dangerously false.
Dr. Jeremy Jackson is considered one of the world's foremost experts on the human impact on the oceans. This talk is a hard-hitting passionate look on the future of the world's oceans, given overfishing, habitat destruction and ocean warming, which have fundamentally changed marine ecosystems and led to "the rise of slime." Although Jackson's work describes grim circumstances, even garnering him the nickname Dr. Doom, he believes that successful management and conservation strategies can renew the ocean's health.
On this week's episode of Talking Radical Radio, climate scientist Paul Beckwith talks about his research as well as about his efforts to push beyond the usual role expected of scientists and engage directly with the public on scientific questions related to climate change. Listen to the radio interview.
New studies in Science and Geophysical Research Letters (GRL) find that glaciers in the Amundsen Sea region of the great Antarctic ice sheet have begun the process of irreversible collapse. That by itself would raise sea levels 4 feet in the coming centuries.
The free pass that frackers and natural-gas handlers have gotten on their climate-changing methane emissions is really starting to stink to high hell. We told you in February about the results of a meta-analysis of 20 years worth of scientific studies, which concluded that the EPA underestimates the natural-gas industry’s climate impacts by 25 to 75 percent, due to methane leakage from its gas dril
Arguments that the climate is relatively insensitive to the increased greenhouse effect have become the last best chance for climate contrarians, but a new study from Texas A&M University hammers a big nail in the coffin of that argument.
