Now that the bad news has dropped, what is the world going to do?

A report issued Sunday by 91 scientists painted a stark portrait of how quickly the planet is heating up and how serious the consequences are. In response, the United Nations secretary general, António Guterres, warned world leaders, “Do what science demands before it is too late.”

The latest figures from the International Energy Agency don’t suggest that many are listening: Carbon dioxide emissions from the energy sector continued to grow through 2017, with a projected rise for 2018, according to the agency.

The next two months will be crucial. In December, experts and officials from around the world will gather in Katowice, Poland, for a new round of international climate negotiations.

What about the Paris Agreement?

Every country agreed, nearly three years ago, to set its own targets to bring down its greenhouse gas emissions. That’s the good news.
