As I write this article, Hurricane Sally is battering communities in the southern United States. At one point this year there were at least seven tropical systems whirling across the Atlantic.

In Antarctica, ocean warming is threatening the Thwaites glaciers, which already account for 5 percent of the global sea level rise. At the opposite pole, a colossal island of ice has broken free from the Arctic’s largest-remaining ice shelf in northeast Greenland.

Meanwhile, record-breaking fires are raging in Western U.S. And a blaze is now threatening one of the most biodiverse ecosystems on the planet — the remote Pantanal wetlands in Brazil. Speaking of the loss of biodiversity, in 2010 in Nagoya, Japan, the United Nations Convention on Biological Diversity set 20 targets to stem the tide of loss. None of them have been fully met.

“We are facing a crisis, and one that has consequences for us all,” says Sir David Attenborough, a prominent British naturalist. Back in the 1970s he was filmed sitting with a band of gorillas, one of them — Poppy — trying to take his shoes off as he spoke to the camera. “It was an experience that stayed with me,” Attenborough says. “But it was tinged with sadness, as I thought I might be seeing some of the last of their kind”.

But we learn that, in fact, the gorillas are now thriving. From about 250 when Attenboorough visited to more than 1,000 in the wild today, it is an example of what is possible.
