Latest Climate model Stories
Brett Smith for redOrbit.com - Your Universe Online According to new research in the Proceedings of the National Academy of Sciences (PNAS), average temperatures in central China are 10 to 14 degrees Fahrenheit hotter today than they were during the last Ice Age 20,000 years ago. The authors of the study predict that these findings, which are two to four times greater than previous models have shown, could help researchers build up more precise models of previous climate change patterns...
The Bureau of Reclamation and collaborators developed new downscaled climate projections that allow water managers to incorporate the new Coupled Model Inter-comparison Project Phase 5 data from the World Climate Research Program into their water management planning. The data, representing 234 contemporary climate projections for the contiguous United States, was downscaled to a 12 kilometer resolution in order to be more useful to water managers. Washington, D.C. (PRWEB) May 09, 2013 The...
redOrbit Staff & Wire Reports - Your Universe Online Temperature patterns during Earth’s last prolonged global “hot spell” some 5.3 million to 2.6 million years ago differed markedly from those of modern times, suggesting current climate models may need to be adjusted to improve future predictions, according to a study published this week in the journal Nature. The Earth was warmer during that time - known as the Pliocene Epoch - than it is today, and had higher carbon dioxide...
NEW YORK, April 2, 2013 /PRNewswire-USNewswire/ -- James E. Hansen, director of NASA's Goddard Institute for Space Studies (GISS) in New York has announced he is retiring as the GISS director and leaving government service. Peter Hildebrand, director of the Earth Sciences Division at NASA's Goddard Space Flight Center in Greenbelt, Md., will serve as interim director until a new director is selected through a competitive process. (Logo:...
Brown University Statistical physics offers an approach to studying climate change that could dramatically reduce the time and brute-force computing that current simulation techniques require. The new approach focuses on fundamental forces that drive climate rather than on “following every little swirl” of water or air. And yes, there’s an app for that. Scientists are using ever more complex models running on ever more powerful computers to simulate the earth’s climate. But new...
redOrbit Staff & Wire Reports – Your Universe Online Climate change is a range of potential events that have a better or worse probability of occurring, and statistics could be a useful tool in helping people better understand how their actions could be adversely affecting the planet, according to new research presented on Friday. The general public’s aversion to statistical thinking and probability is one of the factors that has prevented the implementation of strategies to...
April Flowers for redOrbit.com - Your Universe Online An international group of scientists has shown that global warming from greenhouse gases affects global rainfall patterns differently than global warming from solar heating. Using computer model simulations, the research team showed that global rainfall has increased less over the present-day warming period than during the Medieval Warm Period between 950 and 1250 AD despite the fact that temperatures today are higher than...
Climate scientists are still grappling with one of the main questions of modern times: how high will global temperatures rise if the atmospheric concentration of carbon dioxide doubles. Many researchers are now turning to the past because it holds clues to how nature reacted to climate change before the anthropogenic impact. The divergent results of this research, however, have made it difficult to make precise predictions about the impact of increased carbon dioxide on future warming. An...
At the end of the 21st century, the temperature in the Baltic Sea will be higher and the salt content lower than at any time since 1850. If no action is taken to alleviate the effects of climate change, there may be major consequences for the marine environment. "This is the first time that anyone has taken a detailed look at how climate models and individual factors combine to affect a specific region. This makes this project unique," says Jonathan Havenhand from the Department of...
Lee Rannals for redOrbit.com - Your Universe Online According to a new study, scientific modeling methods that predicated climate change on Earth can also be used on Mars as well. Researchers from Planetary Science Institute in Tucson report they have found that an unusual concentration of glacial features on Mars matches predictions made by global climate computerized models, in terms of age and location. "Some public figures imply that modeling of global climate change on Earth is...
