Latest Carbon dioxide in Earth's atmosphere Stories

Record Carbon Dioxide Levels In 2012, Methane Off The Charts
2013-11-07 12:50:28

Alan McStravick for redOrbit.com - Your Universe Online If you are a fan of random violence occurring worldwide, a new report out this week is right up your alley. While we learned earlier this year that 2012 was the ninth warmest year since 1880, this week we were greeted with news that greenhouse gases, like carbon dioxide, methane and nitrous oxide, hit record highs in that same year. Specifically, carbon dioxide levels have increased a full 41 percent since the start of the...

Forest Ecosystems Keep The Earth From Cooking
2013-10-17 04:10:12

April Flowers for redOrbit.com - Your Universe Online According to a new study led by Princeton University, enhanced growth of the Earth's plants during the 20th century has caused a significant slowdown of the Earth's transition to being "red-hot." This study, the first to specify the extent to which plants have prevented climate change since pre-industrial times, found that land ecosystems have kept the planet cooler by absorbing billions of tons of carbon, especially during the past 60...

Young Sun Paradox Early Climate
2013-10-04 13:46:54

Brett Smith for redOrbit.com - Your Universe Online When life originated on Earth between 3.8 and 2.4 billion years ago during the Archean era, our sun was only functioning at about 75 percent of its current power. With this ‘low wattage’ sun, the Earth should have been covered in glaciers, yet scientists have found no evidence of this taking place. In a new study published recently by the journal Science, a team of international researchers’ analysis of rock samples dating back...

Foraminifera Fossils Reveal An Ice-Free Late Cretaceous Period
2013-09-25 05:04:54

April Flowers for redOrbit.com - Your Universe Online Scientists have long believed that a continental ice sheet formed more than 90 million years ago during the Late Cretaceous Period. During that time, the climate was much warmer than it is today. A new study from the University of Missouri (MU) has found evidence suggesting that this belief is incorrect, that no ice sheet formed during this time. The findings of this study, published in the journal Geology, could help environmentalists...

Ocean Water Vertically Mixes As It Rushes Over Undersea Mountains
2013-09-19 07:58:02

April Flowers for redOrbit.com - Your Universe Online In the ocean near Antarctica, an international research team has solved the mystery of how deep and mid-depth ocean waters are mixed. The study, published in the journal Nature, reveals that sea water mixes dramatically as it rushes over undersea mountains in Drake Passage - the channel between the southern tip of South America and the Antarctic continent. This mixing of oceanic water layers is vital in the regulation of the Earth's...

Climate Change Not Improving NOAA Report
2013-08-07 09:43:37

Brett Smith for redOrbit.com - Your Universe Online Last year was one of the hottest twelve months on record, according to a new report from the National Oceanic and Atmospheric Administration (NOAA) that analyzed global temperatures and climate trends. The US government agency's report was assembled by over 380 scientists from 52 countries. In addition to analyzing temperature data, the annual report also gave the status of other global climate indicators and significant weather...

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...

Oceans May Change Drastically In The Future
2013-08-06 05:37:31

April Flowers for redOrbit.com - Your Universe Online A new study, led by Scripps Institution of Oceanography, reveals the look of the oceans will change drastically in the future as the coming greenhouse world alters marine food webs and gives certain species advantages over others, if history's closest analog is any indication. Richard Norris, paleobiologist at Scripps Institution of Oceanography, UC San Diego, worked with an international team of scientists to show the ancient...

Could Planting Trees In The Desert Take The Edge Off Climate Change?
2013-07-31 12:51:58

European Geosciences Union As the world starts feeling the effects of increasing atmospheric carbon dioxide and consequent global temperature rise, researchers are looking for a Plan B to mitigate climate change. A group of German scientists has now come up with an environmentally friendly method that they say could do just that. The technique, dubbed carbon farming, consists in planting trees in arid regions on a large scale to capture CO2. They publish their study today in Earth System...

WASHINGTON, July 24, 2013 /PRNewswire-USNewswire/ -- NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The researchers discovered a temperature increase of just 1 degree Celsius in near-surface air temperatures in the tropics leads to an average annual growth rate of...
