Study: 178 Fossil Fuel Firms' Past Emissions Will Keep Warming Planet for Centuries

New research finds that 178 major fossil fuel companies have already released enough greenhouse gases to continue raising global temperatures for centuries, even if all of them halted emissions immediately. The study attributes this locked-in warming to carbon already emitted and persisting in the atmosphere, rather than to any future activity.

Study links methane plateau to rising NOx emissions and their southward shift

A new analysis draws on atmospheric measurement records and emission datasets to explain why global methane concentrations temporarily plateaued rather than kept rising. Researchers attribute the pause primarily to increases in nitrogen oxide (NOx) emissions and a geographic shift of those emissions toward the Southern Hemisphere, which altered atmospheric chemistry governing methane's main removal pathway via hydroxyl radicals.
