Study reveals 82% of the core ecological processes that underpin ecosystems and provide services to people are now affected by climate change

Most studies of global climate change attempt to predict what might happen to the Earth as temperatures rise in future.  A new study representing an international collaboration by ecologists and conservation biologists shows that global changes in climate have already impacted every a

Experts call on international climate change panel to better reflect ocean variability in their projections

A commentary on what should be included in the next IPCC special interdisciplinary report on oceans and the cryosphere has been released today in Nature by Daniela Schmidt, Professor of Palaeobiology from the University of Bristol and Philip Boyd, a professor of marine biogeochemistry

Climate, human influence conspired in Lake Urmia's decline

The dramatic decline of Iran’s Lake Urmia—once the second-largest hypersaline lake in the world—has both direct human and climatic causes, according to a new study published in the Journal of Great Lakes Research.   The study was the first to compare the relative impact of climate and

Thawing ice makes the Alps grow

The Alps are steadily “growing” by about one to two millimeters per year. Likewise, the formerly glaciated subcontinents of North America and Scandinavia are also undergoing constant upward movement. This is due to the fact that at the end of the Last Glacial Maximum (LGM) about 18,00

Just 1 Degree C of Warming Has Altered Nearly Every Aspect of Life on Earth

Climate change has already impacted nearly every aspect of life on earth, according to a new study in the journal Science. Warming global temperatures have altered everything from entire ecosystems down to the individual genes of species. Some 80 percent of key ecological processes ex

Rising CO2 Threatens Coral And People Who Use Reefs

As atmospheric carbon dioxide (CO2) levels rise, very few coral reef ecosystems will be spared the impacts of ocean acidification or sea surface temperature rise, according to a new analysis. The damage will cause the most immediate and serious threats where human dependence on reefs

A Major Ocean Current is Widening as Climate Warms

A new study by University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers found that the Indian Ocean’s Agulhas Current is getting wider rather than strengthening. The findings, which have important implications for global climate change, suggest that int

Study: Carbon-Hungry Plants Impede Growth Rate of Atmospheric CO2

New findings suggest the rate at which CO2 is accumulating in the atmosphere has plateaued in recent years because Earth’s vegetation is grabbing more carbon from the air than in previous decades. That’s the conclusion of a multi-institutional study led by a scientist from the Departm

Human health risks from hydroelectric projects

In a new study, Harvard University researchers find over 90 percent of potential new Canadian hydroelectric projects are likely to increase concentrations of the neurotoxin methylmercury in food webs near indigenous communities.  The research forecasts potential human health impacts o

Impact of sea smell overestimated by present climate models

The formation of sulfur dioxide from the oxidation of dimethyl sulfide (DMS) and, thus, of cooling clouds over the oceans seems to be overvalued in current climate models. This concludes scientists from the Leibniz Institute for Tropospheric Research (TROPOS) from a model study on the
