“As we hurtle toward an ever-hotter future, GQ spotlights eight places whose very identities depend on a simple calculation: If we limit warming to 1.5 degrees Celsius above pre-industrial levels, these places could be saved. In a 2-degree scenario, they would be irredeemably lost…Julia Baum, a marine biologist at the University of Victoria, in British Columbia, has been researching climate-threatened coral reefs for years. But recently she decided to make a change. “I’ve realized the best way I can help to save coral reefs is not to work on coral reefs,” she says. “It’s to work on the energy transition.” That’s because climate change is caused chiefly by the burning of fossil fuels, which now accounts for 86 percent of carbon dioxide emissions. And unless we rapidly transition to clean energy, all other efforts to save corals—or our warming planet—won’t matter. This reality is one that all of the earth’s inhabitants are now grappling with: If we want to preserve the places we love, we have to focus on moving away from fossil fuels immediately. The latest United Nations climate report, released in February, made it clear that irreversible destruction can no longer be avoided. The question is no longer “How can we fix climate change?” It’s “How much irreversible planetary damage are we willing to accept in order to continue extracting and burning fossil fuels?”…
