![]() ![]() ![]() “It’s a bit of good news because it shows that the world has made progress in terms of policy and technology over the past few years.” “Those very high emissions trajectories that people used to talk about don’t look quite so likely today,” says Christophe McGlade, head of the energy supply unit at the International Energy Agency and a coauthor of the new paper. And it will only happen if nations carry out their promises to quickly decarbonize their economies-which isn’t guaranteed. It isn’t under the 1.5-degree threshold we’d really want (the agreement’s more optimistic goal), but it’s far from the extreme warming of 3, 4, or even 5 degrees, as some scenarios projected prior to the agreement. That shift is clear in a darn near uplifting paper that publishes today in the journal Nature: Modeling by an international team of scientists shows that if nations uphold their recent climate pledges, including those made at COP26, humanity may keep warming under 2 degrees Celsius above pre-industrial levels, the goal outlined in the Paris Agreement. The price of renewable energy is crashing, for example, and we’re moving toward a cleaner, electrified future faster than you may realize. For all the less-than-encouraging news about climate change-rapid sea-level rise, the land itself transforming, serious trouble brewing under Antarctic glaciers-we’ve been getting plenty of hope.
