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...

Variations In Earth’s Carbon Dioxide Levels Regulated By Tropical Ecosystems
2013-07-23 13:25:45

CSIRO Rising temperatures, influenced by natural events such as El Nino, have a corresponding increase in the release of carbon dioxide from tropical forest ecosystems, according to a new study out today. The study, published in the journal Proceedings of the National Academy of Sciences, found that a temperature anomaly of just 1 degree C (in near surface air temperatures in the tropics) leads to a 3.5-Petagram (billion tonnes of carbon) anomaly in the annual CO2 growth rate, on...

Bioenergy with carbon capture and storage (BECCS) can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially overshoot this target. This is according to a new study, published today, 11 July, in IOP Publishing's journal Environmental Research Letters, which shows that ambitious temperature targets can be exceeded then reclaimed by implementing BECCS around mid-century....

Trees Use Water More Efficiently Due To CO2 Rise
2013-07-11 08:01:38

redOrbit Staff & Wire Reports - Your Universe Online Trees are becoming more efficient at using water in response to higher atmospheric carbon dioxide levels, according to new research published Wednesday in the journal Nature. In the study, researchers including Dave Hollinger from the US Forest Service's Northern Research Station (NRS) and Trevor Keenan of Harvard University analyzed direct, long-term measurements of whole-ecosystem carbon and water exchange. According to...

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....

Global Cooling Versus Global Warming
2013-06-17 05:31:21

Lee Rannals for redOrbit.com - Your Universe Online Scientists writing in the journal Nature Geoscience report that a cold snap which occurred 116 million years ago triggered an event in the marine ecosystem known as global cooling. The researchers said they were able to confirm a link between global cooling and a crash in the marine ecosystem during the mid-Cretaceous greenhouse period. This study quantifies the amplitude and duration of the temperature change for the first time. The...

Purple Urchins Quickly Adapt To Acidic Oceans
2013-06-13 11:41:25

Brett Smith for redOrbit.com - Your Universe Online As the levels of atmospheric carbon dioxide increase, the oceans are projected to absorb more of the greenhouse gas, leading to acidification of the water. This shift in oceanic chemistry is expected to negatively impact countless species. However, a new study from the University of California, Santa Barbara has found that purple sea urchins Strongylocentrotus purpuratus are capable of evolving in a way that copes with potential...
