Global warming and extinction risk

How can fossils predict the consequences of climate change? A German research team from Friedrich-Alexander Universität Erlangen-Nürnberg (FAU), the Museum of Natural History Berlin and the Alfred Wegener Institute compared data from fossil and marine organisms living today to predict which groups of animals are most at risk from climate change. They published their results … Read more Global warming and extinction risk

KAUST global research team first to observe inherited DNA expressions

King Abdullah University of Science and Technology, a graduate research university of science and technology in the Kingdom of Saudi Arabia, today announced new research demonstrating that corals pass patterns of DNA to their offspring. This ground-breaking research marks the first-time this process has been observed in animals within the field of biology. The research … Read more KAUST global research team first to observe inherited DNA expressions

Arctic permafrost thaw plays greater role in climate change than previously estimated

Abrupt thawing of permafrost will double previous estimates of potential carbon emissions from permafrost thaw in the Arctic, and is already rapidly changing the landscape and ecology of the circumpolar north, a new CU Boulder-led study finds. Permafrost, a perpetually frozen layer under the seasonally thawed surface layer of the ground, affects 18 million square … Read more Arctic permafrost thaw plays greater role in climate change than previously estimated

Conflict between ranchers and wildlife intensifies as climate change worsens in Chile

Scientists from the University of La Serena, Newcastle University, UK, and the Pontifical Catholic University of Chile surveyed ranchers to find out what they thought were the drivers of conflict between people and guanacos (a wild camelid species closely related to the Llama). Ranchers blamed the increased aridity for reducing the availability of pasture, which … Read more Conflict between ranchers and wildlife intensifies as climate change worsens in Chile

Global ocean circulation is accelerating from the surface to the abyss

Global Ocean Circulation Is Accelerating from the Surface to the Abyss Contradicting previous studies that suggest global warming will weaken ocean circulation, especially in tropical waters, a new study reports that global ocean circulation has accelerated over the past twenty years, and in tropical waters in particular. This is due to a near 2%-per-decade rise … Read more Global ocean circulation is accelerating from the surface to the abyss

Bubbles transport massive amounts of oxygen to the deep ocean through a marine ‘trap door’

Much more oxygen than previously thought is being transported into deep layers of the ocean through a ‘trap door’ off Canada’s Atlantic coast that some researchers say could be closing as a result of climate change. Scientists from Dalhousie University in Halifax, N.S., and Scripps Institution of Oceanography at the University of California San Diego … Read more Bubbles transport massive amounts of oxygen to the deep ocean through a marine ‘trap door’

Irrigation helps beat the heat of global warming

Large-scale irrigation can help alleviate and even reverse hot extremes driven by human activity and other drivers of global warming, a new international study has found. The research, led by ETH Zurich in Switzerland, showed that irrigation dampens and in some cases offsets the combined effects of global warming on hot days. The researchers compared … Read more Irrigation helps beat the heat of global warming

Crucial reef species may survive ocean changes under climate change

The research, led by Dr Christopher Cornwall from the University’s School of Biological Sciences, showed that coralline algae can build tolerance to ocean acidification, one of the major side-effects of climate change over multiple generations. “Coralline algae go through a natural process of calcification, where they build a calcium carbonate skeleton,” Dr Cornwall says. “Skeletons … Read more Crucial reef species may survive ocean changes under climate change

Climate (not humans) shaped early forests of New England

A new study in the journal Nature Sustainability overturns long-held interpretations of the role humans played in shaping the American landscape before European colonization. The findings give new insight into the rationale and approaches for managing some of the most biodiverse landscapes in the eastern U.S. The study, led by archaeologists, ecologists, and paleoclimatologists at Harvard, Emerson … Read more Climate (not humans) shaped early forests of New England

Density-compensated overturning in the Labrador Sea

A recent study finds that the observed weak linkage between the Labrador Sea convection, a process that mixes surface waters to depth, and the Atlantic Meridional Overturning Circulation (AMOC), a basin-scale circulation critical to the climate system, can be attributed to the density compensation by temperature and salinity. Using observational and reanalysis data, this study … Read more Density-compensated overturning in the Labrador Sea
