Carol Rasmussen, NASA Earth Science News Team NASA's Orbiting Carbon Observatory-2, which launched on July 2, will soon be providing about 100,000 high-quality measurements each day of carbon dioxide concentrations from around the globe. Atmospheric scientists are excited about that. But to understand the processes that control the amount of the greenhouse gas in the atmosphere, they need to know more than just where carbon dioxide is now. They need to know where it has been. It takes more...

First Comprehensive State-level Climate Assessment Released By Vermont
2014-06-11 03:19:17

By Joshua E. Brown, University of Vermont Fewer days for making maple syrup. Twenty-five years with more snow for skiing. Summer heat stress for dairy cows. These are a few of the forecasts from the Vermont Climate Assessment, the nation's first comprehensive state-level climate assessment, released on June 10. The Vermont report is partnered with the National Climate Assessment, presented by the White House in May. It is expected to be the first of many state-level efforts to...

Unclouding Our View Of Future Climate
2014-05-22 03:58:27

[ Watch The Video: Atmospheric General Circulation Changes Due To Increased Greenhouse Gases ] Carol Rasmussen, NASA's Jet Propulsion Laboratory If we had a second Earth, we could experiment with its atmosphere to see how increased levels of greenhouse gases would change it, without the risks that come with performing such an experiment. Since we don’t, scientists use global climate models. In the virtual Earths of the models, interlocking mathematical equations take the place...

Unraveling Mystery Of Retreating Glaciers In The Pacific Ocean's Western Tropics
2014-03-14 11:39:06

University of California - Los Angeles Using a cutting-edge research technique, UCLA researchers have reconstructed the temperature history of a region that plays a major role in determining climate around the world. The findings, published online Feb. 27 in the journal Nature Geoscience, will help inform scientists about the processes influencing global warming in the western tropical Pacific Ocean. The study analyzes how much temperatures have increased in the region near...

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...

Sun's Increasing Brightness Will Dry Out The Earth In A Billion Years

[ Watch the Video: The Sun Will Evaporate Our Oceans Eventually ] Ranjini Raghunath for redOrbit.com - Your Universe Online One billion years from now, all the water on Earth could disappear, making it barren like Venus, and the culprit isn’t climate change. It’s the Sun, according to a new study published in the journal Nature. Scientists have previously predicted that, even without climate change, the Earth’s surface would still heat up, because of the Sun’s increasing...

First comprehensive survey shows 60 percent rise over last 30 years of floods, droughts and storms Europe needs to plan for future probabilities of extreme weather. Heat waves, floods and storms do not respect national frontiers, so there is a need for action at both national and EU levels. The IPCC has advised that the frequency of many types of extreme weather events will continue to grow globally in coming years. Now the national science academies of EU Member States bring into focus...

Pollution Causes Thunderstorms To Leave Lingering Clouds
2013-11-26 15:18:22

Pacific Northwest National Laboratory Study shows why pollution results in larger, deeper and longer lasting storm clouds, leading to colder days and warmer nights A new study reveals how pollution causes thunderstorms to leave behind larger, deeper, longer lasting clouds. Appearing in the Proceedings of the National Academy of Sciences November 26, the results solve a long-standing debate and reveal how pollution plays into climate warming. The work can also provide a gauge for the...

Climate Science Boost With Tropical Aerosols Profile
2013-08-02 12:59:57

CSIRO The seasonal influence of aerosols on Australia's tropical climate can now be included in climate models following completion of the first long-term study of fine smoke particles generated by burning of the savanna open woodland and grassland. Australia's biomass burning emissions comprise about eight per cent of the global total, ranking third by continent behind Africa (48 per cent) and South America (27 per cent). Lead researcher, CSIRO's Dr Ross Mitchell, said fine particles...

Early Earth Relied On Carbon To Keep Warm Enough For Life
2013-07-10 13:58:57

Lee Rannals for redOrbit.com - Your Universe Online University of Colorado Boulder researchers have figured out how early Earth was warm enough to support life when the sun was 20 per cent dimmer than today. A new study determined that all that may have been required to sustain liquid water and primitive life on Earth during the Archean eon, 2.8 billion years ago, were the reasonable atmospheric carbon dioxide amounts believed to be present at the time and a little bit of methane....


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
