Nika Knight – Humans Have Pushed Oceans to Their Absolute Limit, Warns Report

The effect of climate change on the world’s oceans has been understudied, a recent report from the International Union for the Conservation of Nature (IUCN) finds, and it is far worse than many scientists and politicians had previously thought. “We all know the oceans sustain this planet,” said Inger Andersen, IUCN’s director general, to National Geographic, “yet we are making the oceans sick.” …

Climate change could trigger tropical evacuations, researchers advise

Global warming by just 2 degrees Celsius is likely to force some tropical plant, animal and human populations to relocate hundreds of miles from their current homes this century, according to research published today in the journal Scientific Reports. Solomon Hsiang, Chancellor’s Associate Professor of Public Policy at the University of California, Berkeley, and Adam Sobel, a professor of applied physics …

Human impacts fuel weather extremes

The serious floods that hit southern England in the winter of 2013-14 were at least partly a consequence of climate change driven by the global warming that results from fossil fuel combustion. To be precise, the extreme rainfall that led to £431 million (US$622 million) of damage was made 43% more likely by human-induced climate change, according to a new …

Plants may run out of time to grow under ongoing climate change

A key potential ‘benefit’ of global warming–namely, that plants at northern latitudes will thrive in a warmer world–is challenged by a new study released by University of Hawai’i scientists today. The prevailing assumption ignores the fact that plants in the North will remain limited by solar radiation, curbing positive effects of warming and additional CO2 availability. In addition, that same warming …
