Frequent strandings of humpback whales seem to be caused by malnutrition.

I can see various ways in which effects of global heating could be contributing to this. For instance, it the whales giving birth could have moved away from the equator for the temperature and perhaps there is not enough to eat in the place they have moved to.

This is a hunch, not a certainty. The certainty is that global heating will mess up lots of ecosystems.

Polar bears in the area around Svalbard are having 1/3 as many cubs as usual. Probably because receding ice has made it hard for them to find food.

A giant forest fire is burning in Alaska, 243 square miles in size. And it's not even summer yet.

You can guess what caused this.

The head of the IMF says that income and wealth inequality is harmful, recommending that states provide education and health care, tax the rich more, and regulate banks strictly.

Will any governments listen when the IMF says such things?

The government of Canada and that of Alberta are attacking science, journalism and civil society to protect the tar sands oil extraction from criticism.

This includes calling Greenpeace "extremists", firing and gagging scientists, spying on environmental groups, and deporting journalists.

We think of oil wells as occupying a small spot on the ground. We don't realize that extracting tar sands involves massive deforestation. It seems to be a kind of strip-mining.

A US judge says he thinks somewhere between 1 and 8 percent of defendants plead guilty although they are innocent, to escape long mandatory sentences.
