WILLIAM BRANGHAM:

But first: President Trump announced over the weekend that he will decide this week whether the U.S. will remain part of the Paris climate accord.

That accord, signed last year by 195 countries, commits those nations to significantly reduce their carbon emissions to combat climate change. But President Trump has long argued that environmental regulations cost American jobs, and he's vowed to undo them, and he's also described climate change itself as a hoax. European leaders last week urged the president not walk away from the accord.

In Scandinavia, which is a world leader in green technology, politicians and environmentalists want the president to follow their lead, and increase investment in environmentally friendly technologies like electric cars.
