The loss of biodiversity is now ruining ecosystems on more than half of the world’s land. A loss of more than 10% is used as the norm for setting the safety limit, beyond which ecosystems can no longer function properly. This study was focused on consequences of the direct human destruction of habitat. Global warming/climate change contributes to the overall diversity loss in other ways and in practically all other places, including waters.

A new study about ice loss from the Antarctic Peninsula. This region, which holds 4% of the continent’s ice, is also its fastest melting. Air temperatures in the region have been rapidly rising, and now there is evidence of a considerable contribution from warm ocean currents that are attacking the coastal edges of hundreds of relatively small glaciers.

Unusual warming of Arctic waters. The Arctic Ocean is bordered by eight integrated seas, plus numerous bays, channels and gulfs, where ice is now rapidly retreating. Surface water temperatures throughout the area are now being revealed at 4C or more above what was normal just a few decades ago—kind of crazy.
A similar picture can be found at the more familiar U of Maine reanalyzer site. Here you can scroll down and see what a huge difference there is in the water temperature anomalies around Antarctica.

Human populations in the Serengeti ecosystem are being squeezed. Some 800,000 people who live outside the national parks are exposed to a climate that is harsh to begin with and keeps getting drier. Their once nomadic way of life is no longer viable.

A new study about the intensity of tropical cyclones, which has not increased to the extent that many have expected. The Abstract you can read here (without paying) briefly explains why that is so, and makes predictions for the future.

A new concentrating solar power plant with advanced molten-salt technology. Future cost reductions could make this technique a strong contender for lowest cost solar production on a utility scale.
