Study highlights pathways to cut emissions and lower climate and health risks.

Hydrogen fuel has long been seen as a potentially key component of a carbon-neutral future. At the 2022 MIT Energy Initiative Spring Symposium, industry experts describe efforts to produce it at scale.

New climate change ecology research links the amount of carbon dioxide taken in by land ecosystems, such as forests, to the availability of water.

Thanks to humans, the concentration of planet-warming carbon dioxide in the atmosphere is now 50% higher than before the industrial era. These gases are raising Earth’s temperature.

Thanks to humans, the atmosphere has 50% more planet-warming carbon dioxide today than it did before the industrial era. Those gases will continue raising Earth’s temperature for years.

A textile filter made from cotton and an enzyme that speeds chemical reactions shows promise for removing CO2 from air and gas mixtures.

"This bacterial enzyme is the most efficient carbon fixer that we know of, and we came up with a neat explanation of what it can do."

The Earth is a resilient planet, but people are altering it in ways that may take centuries to reverse.

Using our oceans as carbon sinks could help achieve climate goals set in the most recent IPCC report.

A new chemical technique "is a great way to have one problem, plastic waste, address another problem, CO2 emissions," says James Tour.
