Future increase in plant photosynthesis revealed by seasonal carbon dioxide cycle
Oct 03, 2016
Doubling of the carbon dioxide concentration will cause global plant photosynthesis to increase by about one third, according to a paper published in the journal Nature.
Giant algal bloom sheds light on formation of White Cliffs of Dover
Sep 20, 2016
A great algae bloom at the bottom of the world is teaching scientists more about how an iconic symbol of the United Kingdom came to be.
Marine macroalgae removes large amounts of atmospheric carbon
Sep 12, 2016
Our understanding of the global carbon cycle has been reshaped by KAUST researchers who have helped to reveal a major role for the abundance of seaweed growing around the world's coasts.
Calculating the role of lakes in global warming
Sep 07, 2016
As global temperatures rise, how will lake ecosystems respond? As they warm, will lakes—which make up only 3 percent of the landscape, but bury more carbon than the world's oceans combined—release more of the greenhouse ...
Biomass turnover time in ecosystems is halved by land use
Aug 23, 2016
In order to improve our understanding of climate change and to increase the predictability of future dynamics, it is necessary to gain a better understanding of the global carbon cycle. To date, little is known about the ...
Limestone assimilation under volcanoes helps understand Earth's carbon cycle
Aug 08, 2016
In a new study researchers from Sweden and Italy show what happens when magma meets limestone on its way up to the surface. Magma-limestone interaction might help explain why volcanoes like Vesuvius in Italy and Merapi in ...
The outer edge of a star's habitable zone a hard place for life
Jul 12, 2016
Earth is situated right in the middle of our Sun's habitable zone and it's a comfortable place for life. We enjoy a relatively stable climate and the right amount of warmth to allow liquid water.
NASA's field campaign investigates Arctic North American ecosystems
Jul 08, 2016
Sampling charred soils in Saskatchewan, outfitting robins with GPS backpacks in Alberta, and measuring the growth rates of trees in northern Alaska - scientists with a decade-long NASA project are in the field this summer ...
Microbes, nitrogen and plant responses to rising atmospheric carbon dioxide
Jun 30, 2016
Plants can grow faster as atmospheric carbon dioxide concentrations increase, but only if they have enough nitrogen or partner with fungi that help them get it, according to new research published this week in Science.
Warning from the past: Future global warming could be even warmer
Jun 23, 2016
Future global warming will not only depend on the amount of emissions from man-made greenhouse gasses, but will also depend on the sensitivity of the climate system and response to feedback mechanisms. By reconstructing past ...
