There’s a stubborn, heat-absorbing particle that floats along in Earth’s atmosphere: It initially doesn’t like water, it absorbs light, and it takes its time moving on. Black carbon in the atmosphere tends to linger until it finally absorbs enough water to fall from the sky. In the ...
various depths through the ocean. The researchers entered the data points from the curve into each alternative equation. They then ran each equation through the MITgcm, a general circulation model that simulates, among other processes, the flux of carbon dioxide betwe...
The ocean’s “biological pump” describes the many marine processes that work to take up carbon dioxide from the atmosphere and transport it deep into the ocean, where it can remain sequestered for centuries. This ocean pump is a powerful regulator of a
For example, despite notable gains for electric vehicles in some countries, gas-fired cars will be operating well into the future. And some industries, like shipping and aviation, are challenging to fully decarbonize. “We have to remove some of what’s in the atmosphere in add...
