It’s been a whirlwind week in the news. On Monday, President Trump was accused of freezing aid to Ukraine before pressing the country’s leader to investigate a political rival. By Tuesday, Nancy Pelosi, the House speaker, announced a formal impeachment inquiry against the president, and, for much of the last few days, cable news, social media, late-night comedy shows and most news sites have talked of little else.

Still, perhaps you heard a bit about the climate talks at the United Nations, where the teenage climate activist Greta Thunberg criticized world leaders for their “business as usual” approach. Or the continuing political turmoil in Britain, where the Supreme Court struck down Prime Minister Boris Johnson’s suspension of Parliament. Or the negotiations to form a government in Israel, in which Prime Minister Benjamin Netanyahu pulled off an amazing reversal and came out on top once again.

Here are some other stories you may have missed.

The oceans are in danger

A sweeping United Nations report found that climate change is dramatically altering the chemistry of the world’s oceans. They are heating up quickly, threatening seafood supplies, fueling cyclones and floods, and posing profound risks to hundreds of millions of people who live along the coasts, the report found.

Written by more than 100 international experts and based on more than 7,000 studies, the report is the most extensive look to date at the effects of climate change on oceans, ice sheets, mountain snowpack and permafrost.
