This unlikely fuel could power cleaner trucks and ships

Transportation is a huge piece of the climate puzzle, accounting for over 15% of worldwide global greenhouse gas emissions. And while we’re making steady progress, there are parts of the puzzle that are harder to solve, like vehicles that need to cover long distances or run for long durations without stopping to charge.

New York–based startup Amogy thinks the key to solving this problem lies in harnessing ammonia—one of the world’s most widely shipped chemicals—to power electric tractors, trucks, and even ships. 

Casey Crownhart, our climate reporter, visited its headquarters to hear more about the team’s big ideas. Read the full story.

The big story

The Atlantic’s vital currents could collapse. Scientists are racing to understand the dangers.

December 2021

Scientists are searching for clues about one of the most important forces in the planet’s climate system: a network of ocean currents known as the Atlantic Meridional Overturning Circulation (AMOC). They want to better understand how global warming is changing it, and how much more it could shift, or even collapse.

The problem is the Atlantic circulation seems to be weakening, transporting less water and heat. Because of climate change, melting ice sheets are pouring fresh water into the ocean at the higher latitudes, and the surface waters are retaining more of their heat. Warmer and fresher waters are less dense and thus not as prone to sink, which may be undermining one of the currents’ core driving forces. Read the full story.
