long term warming trend
2014-03-11 12:20:13

WASHINGTON, March 11, 2014 /PRNewswire-USNewswire/ -- A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. This research hinges on a new and more detailed calculation of the sensitivity of Earth's climate to the factors that cause it to change, such as greenhouse gas emissions. Drew Shindell, a climatologist at NASA's Goddard Institute for Space Studies in New...

Decreasing Cloud Cover Could Mean Higher Global Temperatures

[ Watch the Video: Fewer Clouds Could Mean Hotter Temperatures ] Gerard LeBlond for redorbit.com - Your Universe Online A study by the University of NSW (UNSW) claims that the Earth’s temperatures will rise 7.2 degrees Fahrenheit by the end of the century. Earlier predictions that were based on cloud cover forecast a smaller increase and were most likely wrong, according to the study, to be published January 1, 2014 in the journal Nature. This could mean catastrophic results for...

long term climate feedback loop
2013-08-06 10:24:29

Brett Smith for redOrbit.com - Your Universe Online According to University of Hawaii at Manoa oceanographer Richard Zeebe, future warming due to the current burning of fossil fuels will cause the Earth's global temperatures to rise longer than expected. In his report, which was published in Proceedings of the National Academy of Sciences, Zeebe looked at the long-term climate effects of today's human activity thousands of years into the Earth's future. "When we talk about climate...

Global Warming May Not Be Quite As Bad As Feared
2013-01-25 13:39:58

Lee Rannals for redOrbit.com - Your Universe Online New estimates from a Norwegian research project show that policymakers attempting to contain global warming at less than 3.6 degrees Fahrenheit have an attainable target. While most news that comes out about global warming is typically negative and ominous, this study has put a slightly more positive twist on the unfolding story of climate change. “These results are truly sensational,” said Caroline Leck of Stockholm...

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...

Sunblock For The Earth

April Flowers for redOrbit.com - Your Universe Online When you want to protect your skin from the harmful rays of the Sun, you employ some sort of sun block. It might be a lotion or a cream; it might even be a shirt or an umbrella to filter the effects. But what would you use to protect the entire planet from the Sun? Apparently that is the question that an increasing number of scientists are trying to answer; ways to temporarily reduce the amount of sunlight reaching the Earth to stave...

Scientists have developed important new insight into the sensitivity of global temperature to changes in the Earth´s radiation balance over the last half million years. The sensitivity of global temperature to changes in the Earth´s radiation balance (climate sensitivity) is a key parameter for understanding past natural climate changes as well as potential future climate change. In a study in Journal of Climate, researchers from the Universities of Southampton and Bristol for...

IPCC 2007 Estimates Of Global Warming Challenged By Scientists
2011-11-25 13:02:28

According to a new study published this week in Science, the rate of global warming from doubling of atmospheric carbon dioxide may be less than previous estimates. The study authors said that global warming is real and that increases of atmospheric CO2 will have multiple serious impacts.  However, the most Draconian projections of temperature increases from the doubling of CO2 are unlikely, which is a projection made by the Intergovernmental Panel on Climate Change (IPCC) in 2007....

The kinds of increases in atmospheric carbon dioxide taking place today could have a significantly larger effect on global temperatures than previously thought, according to a new study led by Yale University geologists. Their findings appear December 20 in the advanced online edition of Nature Geoscience. The team demonstrated that only a relatively small rise in atmospheric carbon dioxide (CO2) was associated with a period of substantial warming in the mid- and early-Pliocene era, between...
