A warming climate is not just melting the Arctic’s sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country’s waters, says a new study. The new study, which maps the movement of sea ice in the region, underscores the risk of contaminated sea ice drifting from the economic zone of one country to another’s.

Growing plants and then storing the carbon dioxide they have taken up from the atmosphere is not a viable option to counteract unmitigated emissions from fossil fuel burning, a new study shows. Plantations would need to be so large they would eliminate most natural ecosystems or reduce food production if implemented as a late-regret option in the case of substantial failure to reduce emissions, according to the study.

A new study published in Earth’s Future, a journal of the American Geophysical Union, explores the impact of development on local wind patterns and dune formation on one of Spain’s Canary Islands. By reviewing aerial photographs and topographical measurements, the study’s authors watched how a city’s expansion altered local wind patterns and ultimately changed the surrounding landscape, jeopardizing the long-term sustainability of a major tourist destination.

Countries unable to feed their growing populations are increasingly importing food to meet demand, a new study finds. Nearly half of the world’s population lives in areas where imports compensate for food scarcity and one-fifth of the world now depends upon these imports to survive, according to the new study.

Each year, as sea ice starts to melt in the spring following its maximum wintertime extent, scientists still struggle to estimate exactly how much ice they expect will disappear through the melt season. Now, a new NASA forecasting model based on satellite measurements is allowing researchers to make better estimates.

A new report looks at flood risk and economic damages under different global warming scenarios with temperature increases of 1.5 degrees Celsius, 2 degrees Celsius and 4 degrees Celsius. It concludes that, if global temperatures rise by 4 degrees Celsius, the flood risk in countries representing more than 70 percent percent of the global population and global GDP will increase by more than 500 percent.

The phrase “tipping point” passed its own tipping point and caught fire after author Malcolm Gladwell’s so-named 2000 book. It’s now frequently used in discussions about climate change, but what are “climate tipping points”? And what do they mean for society and the economy?

“This is a major source of climate change that has not been looked at,” said John Murray of The Open University in Milton Keynes, England and lead author of the new study accepted for publication in Earth’s Future, a journal of the American Geophysical Union. “Any kind of energy consumption generates heat” Murray said.

The climate of Dubai is quickly growing less hospitable, according to authors of a new study.

A future warming of the Southern Ocean caused by rising greenhouse gas concentrations in the atmosphere may severely disrupt the stability of the West Antarctic Ice Sheet, which would raise sea levels by several meters, according to new research. A temperature increase of 2 degrees Celsius (3.6 degrees Fahrenheit) would be enough to initiate irreversible melting of the ice sheet, the new study found.
