Earth's Lakes Are Warming Faster Than The Oceans And Atmosphere

Associated Press: Some of the world's biggest temperature jumps are happening in lakes an ominous sign that suggests problems such as harmful algae blooms and low-oxygen zones hazardous to fish will get worse, says a newly released scientific report. An analysis of 235 lakes that together hold more than half the earth's fresh surface water found they have warmed an average of 0.61 degrees Fahrenheit or 0.34 degrees Celsius per decade, the report said. While seemingly insignificant, the increase is bigger than...

Scientists paint a detailed picture of the chemical structure of oceans 520 million years ago
2015-12-11 13:00:00| LifeSciencesWorld
[NEWS] Ocean chemistry has strongly shaped the evolution of life and biogeochemical cycles on the Earth. Although it was known that the early oceans (>520 million years ago) were characterized by strong water-column stratification and limited oxidant availability, the detailed chemical structure of early Earth oceans has remained unclear. Recently, researchers in Wuhan have developed a model of the spatial structure of early-Earth ocean chemistry that significantly advances our understan…

Rapid plankton growth seen as indicator carbon dioxide loading in oceans
2015-11-27 19:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: A microscopic marine alga is thriving in the North Atlantic to an extent that defies scientific predictions, suggesting swift environmental change as a result of increased carbon dioxide in the ocean, a study led a by Johns Hopkins University scientist has found. What these findings mean remains to be seen, as does whether the rapid growth in the tiny plankton's population is good or bad news for the planet. Published today in the journal Science, the study details a tenfold increase in the abundance...

Oceans, ocean activism, deserve broader role in climate change discussions

ScienceDaily: When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet. Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people -- including the world leaders who will gather later this month in Paris for the latest round of climate change negotiations -- should pay more attention to how climate change's...

NASA to study how plants and oceans absorb carbon
2015-11-14 01:52:00| Climate Ark Climate Change & Global Warming Newsfeed
Jagran Post: rowing carbon emissions have become a concern for ecologists across the world and if these ecosystems someday stop absorbing carbon, the effects of climate change could be much more severe, scientists said. NASA estimates that nearly half of the carbon emitted by humans is absorbed through these natural land and marine processes. But the agency is worried that it may change. As the carbon in the atmosphere warms up the climate, the heat may alter how marine and land ecosystem absorb carbon, The...
