Human-caused climate change appears to have driven the Great Barrier Reef’s only endemic mammal species into the history books, with the Bramble Cay melomys, a small rodent that lives on a tiny island in the eastern Torres Strait, being completely wiped-out from its only known location.

It is also the first recorded extinction of a mammal anywhere in the world thought to be primarily due to human-caused climate change.

Oregon regulators are studying how to design an economywide carbon cap-and-trade system that would be able to link with other similar programs in neighboring states and provinces.

The saber-toothed cat, large ground sloth and other ice age giants of South America didn't go extinct solely because of climate change or prehistoric human activity, but because of a perfect storm of the two that hit the giant beasts at the same time, a new study finds.

For years, researchers have debated what felled many of the megafauna — animals that weigh more than 100 lbs. (45 kilograms) — shortly after the end of the last ice age. Some scientists blamed humans, who had newly colonized the Americas, while others pointed to the warming climate that followed the last ice age.

When it comes to confronting climate change, the world’s cities are proving that there’s strength in unity. The historic climate agreement reached in Paris in December, which was approved by nearly all of the world’s nations, was made possible in part by the progress that cities have made by working together.

Rich countries must ratify the climate change agreement reached in Paris last December, one of the world’s most at-risk nations has warned.

Support for strong action on climate change is at its highest level since 2008, with much sought after uncommitted voters showing the strongest support, according to Galaxy polling commissioned by the Climate Institute.

Rising temperatures are posing a threat to global food security.

The University of Cambridge has been criticized for not divesting from oil and gas companies, despite pressure from students and academics to do so.

The decision comes after a year in which the university has faced intense pressure on its fossil fuel investments which saw over 2,000 students sign a petition for divestment, while the students’ union council voted 33:1 in favor of divestment.

A group of business and academic leaders have bemoaned the “huge gap” between what experts say ought to be done to decarbonize Australia’s economy and the public’s willingness to accept such a policy.

They want Australia’s leaders to restart a conversation after the federal election about the need to transition the economy towards renewable and cleaner energy.

The United States, Canada and Mexico will promise on Wednesday to generate half their overall electricity from clean energy by 2025, the White House said.

"We believe it is an aggressive goal, but that it is achievable continent-wide," Brian Deese, senior advisor to US President Barack Obama, said Monday.
