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...

Antarctic Ozone Hole Is Shrinking
2012-09-15 08:17:08

April Flowers for redOrbit.com - Your Universe Online The United Nations reported Friday that the hole in the ozone layer is expected to be smaller this year over the Antarctic than last year. They claim this illustrates how a ban on harmful substances has slowed ozone depletion. The ozone layer in the Earth's atmosphere contains relatively high concentrations of ozone (03).  This layer is found mainly in the lower portion of the stratosphere and absorbs 97 — 99% of the Sun's...

NASA Study Shows Health, Food Security Benefits From Climate Change Actions

A new study led by a NASA scientist highlights 14 key air pollution control measures that, if implemented, could slow the pace of global warming, improve health and boost agricultural production. The research, led by Drew Shindell of NASA's Goddard Institute for Space Studies (GISS) in New York City, finds that focusing on these measures could slow mean global warming 0.9 ºF (0.5ºC) by 2050, increase global crop yields by up to 135 million metric tons per season and prevent...

First time that ozone depletion is shown to impact the entire circulation of the southern hemisphere In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator. While previous work has shown that the ozone hole is changing the...

A new analysis, published last week and conducted by a team of scientists led by Drew Shindell of NASA's Goddard Institute for Space Studies (GISS) in New York City, shows stricter vehicle emission standards would yield major health, agricultural, and climate benefits. Shindell and colleagues used a comprehensive computer model and climate simulator -- one of the first capable of accounting for the role of short-lived particles expelled in vehicle fumes called aerosols -- that shows vehicle...

By Adam Voiland, NASA's Earth Science News Team An assessment report to be released this week by the United Nations Environment Program and the World Meteorological Organization shows that reducing emissions of two common air pollutants -- black carbon and gases integral to the production of ground-level ozone -- could slow the rate of climate change markedly over the next half-century. For decades, scientists have known both substances harm human health. More recently, evidence has emerged...

Wildfires may seem like a fixed and unchanging force of nature. They're not. Over long time scales, research has shown that both the climate and humans have a profound effect on wildfire activity around the globe. Now new NASA research shows that while we have been suppressing this natural force for the past century, we may be, inadvertently, about to put nature back in control. Charcoal layers in sediments and methane concentration in ice cores show that the amount of global burning can...

For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth's climate. And they've been aided by ever more sophisticated computer models that make estimating the relative impact of each type of pollutant more reliable. Yet the complexity of nature -- and the models used to quantify it -- continues to serve up surprises. The most recent? Certain gases that cause warming are so closely linked with the...

The U.S. space agency's Aura spacecraft began its sixth year of research this week, studying Earth's ozone layer, air quality and climate. The satellite, launched July 15, 2004, from California's Vandenberg Air Force Base, has transmitted data that is helping scientists address global climate change issues such as global warming; the distribution and chemistry of polluted air, and ozone depletion in the Earth's stratosphere, space agency scientists said. NASA's Goddard Space Flight Center in...
