The pattern of uneven sea level rise over the last quarter century has been driven in part by human-caused climate change, not just natural variability, according to a new study.
A simple molecule in the atmosphere that acts as a 'detergent' to breakdown methane and other greenhouse gases has been found to recycle itself to maintain a steady global presence in the face of rising emissions, according to new NASA research. Understanding its role in the atmosphere is critical for determining the lifetime of methane, a powerful contributor to climate change.
Researchers at Tokyo Tech have designed a CO2 reduction method based only on commonly occurring elements. Achieving a 57 percent overall quantum yield of CO2 reduction products, it is the highest performing system of its kind reported to date, raising prospects for cost-effective carbon capture solutions.
In August 2012, the Jakobshavn Glacier was flowing and breaking off into the sea at record speeds, three times faster than in previous years. As the glacier flowed faster, it became thinner and more unstable and in a twist, a pileup of thick ice replenished the glacier's terminus, slowing it down again. New work explaining the fast-then-slow movement of Jakobshavn may help scientists better predict how tidewater glaciers contribute to sea level rise.
When Tropical Cyclone 33W, also known as Usagi strengthened to hurricane intensity as it approached Vietnam from the South China Sea it dropped a lot of rain. Although the storm weakened to tropical storm intensity when coming ashore in Vietnam, it continued to generate a lot of rain, and NASA added up that heavy rainfall.
IIASA researchers have contributed to a major new report in The Lancet medical journal looking at the effects of climate change on human health, and the implications for society.
The University of Bern was involved in a new study that has found two types of climatic connection between the North Atlantic and Antarctica. One is a rapid atmospheric channel and the other a much slower connection through the ocean. During the last glacial period, these links resulted in abrupt climatic changes -- and could so again in future.
New research reveals the extinction of plant or animal species from extreme environmental change increases the risk of an 'extinction domino effect' that could annihilate all life on Earth. This would be the worst-case scenario of what scientists call 'co-extinctions', where an organism dies out because it depends on another doomed species, with the findings published today in the journal Scientific Reports.
A prediction lead time of about 2 to 5 weeks is sorely lacking in current forecasting capabilities for severe weather. In a new paper, Colorado State University atmospheric scientists demonstrate the ability to make skillful predictions of severe weather across the Plains and southeastern United States, including hail and tornadoes, in that coveted "subseasonal" time scale. To do it, they use a reliable tropical weather pattern called the Madden-Julian Oscillation, which can influence weather in distant parts of the Earth.
The complex network of interdependencies between plants and animals multiplies the species at risk of extinction due to environmental change.
