Carbon pollution from high flying rich in private jets soars

Carbon pollution from private jets has soared in the past five years, with most of those small planes spewing more heat-trapping carbon dioxide in about two hours of flying than the average person does in about a year, a new study finds. About a quarter million of the super wealthy — worth a total of […]

In the gateway to the Arctic, fat, ice and polar bears are crucial. All three are in trouble.

ON HUDSON BAY — Searching for polar bears where the Churchill River dumps into Canada’s massive Hudson Bay, biologist Geoff York scans a region that’s on a low fat, low ice diet because of climate change. And it’s getting lower on polar bears. There are now about 600 polar bears in the Western Hudson Bay, […]
