Carbon-sequestering Ocean Plants May Handle Climate Changes Over The Long Run
2013-08-26 14:33:35

San Francisco State University A year-long experiment on tiny ocean organisms called coccolithophores suggests that the single-celled algae may still be able to grow their calcified shells even as oceans grow warmer and more acidic in Earth's near future. The study stands in contrast to earlier studies suggesting that coccolithophores would fail to build strong shells in acidic waters. The world's oceans are expected to become more acidic as human activities pump increasing amounts of...

Animal Species Ocean Acidification
2013-08-26 09:36:17

Brett Smith for redOrbit.com - Your Universe Online When atmospheric carbon dioxide dissolves into the ocean, it forms carbonic acid, which in turn lowers the water's pH levels and causes oceanic acidification. The phenomenon is expected to occur at increasing rates as carbon dioxide emissions around the world continue to rise. In a report published in Nature Climate Change, two researchers from the Alfred Wegener Institute, Helmholtz-Centre for Polar and Marine Research (AWI) in...

Understanding Marine Life's Ability To Adapt To Climate Change
2013-08-26 06:03:13

University of Plymouth A study into marine life around an underwater volcanic vent in the Mediterranean, might hold the key to understanding how some species will be able to survive in increasingly acidic sea water should anthropogenic climate change continue. Researchers have discovered that some species of polychaete worms are able to modify their metabolic rates to better cope with and thrive in waters high in carbon dioxide (CO2), which is otherwise poisonous to other, often...

Extreme Weather Adds To Warming
2013-08-15 05:05:21

redOrbit Staff & Wire Reports - Your Universe Online Extreme weather and climate events such as heavy precipitation, violent storms, heat waves and lengthy droughts cause terrestrial ecosystems to absorb approximately 11 billion tons less carbon dioxide each year, according to new research appearing in the latest edition of the journal Nature. That is equivalent to approximately one-third of global CO2 emissions each year, according to an international team of researchers led by...

No Clear Sign That Less Soot, Methane Reduces Global Warming
2013-08-14 08:20:43

redOrbit Staff & Wire Reports - Your Universe Online Reducing emissions of only soot and methane won't do as much to reduce global warming as some previous research has suggested, according to a new study published Monday in the Proceedings of the National Academy of Sciences (PNAS). "Cutting back only on soot and methane emissions will help the climate, but not as much as previously thought," said study author Steve Smith, a climate researcher at the Department of Energy's Pacific...

Worm Causing Methane Release Ocean Bed
2013-08-13 08:36:26

April Flowers for redOrbit.com - Your Universe Online A super-charged methane seep has been discovered in the ocean off the coast of New Zealand. The seep has created its own unique food web, resulting in elevated amounts of methane escaping from the ocean floor into the water column, according to scientists at Oregon State University. Methane is a greenhouse gas 23 times more potent than carbon dioxide at warming our atmosphere. Most of the methane in the seep is likely consumed by...

Forests have a limited capacity to soak up atmospheric carbon dioxide, according to a new study from Northern Arizona University. The study, available online in the journal New Phytologist, aimed to explore how rising atmospheric carbon dioxide could alter the carbon and nitrogen content of ecosystems. By performing tests on subtropical woodland plots over an 11-year period, the researchers found that ecosystem carbon uptake was not significantly increased by the high CO2...

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...

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
