The increase from 2023 was small—0.8 percent—but still, global emissions continue to rise, despite science telling us we should have bent the global emissions' curve downward by 2020. As we near 1.5 degrees Celsius of global warming—the globally agreed upon limit of the Paris Agreement—we risk triggering tipping points. Many tipping elements are now well-known: the Amazon rainforest, the Greenland Ice Sheet, the Atlantic Meridional Overturning Circulation (or AMOC). But exactly at what level of warming they will cross their tipping points is still being investigated and narrowed down by science. The largest coral reef in the world and the richest marine ecosystem on Earth—the Great Barrier Reef in Australia—experienced another mass bleaching event in 2025.
