PLEASE READ UN REPORT ON CLIMATE CHANGE.
The difference between 1.5 degrees and 2 degrees would be substantial. Coral reefs would go from mostly gone to almost entirely gone. More sea-level rise would put up to 10 million more people in danger. High heat would kill more people. It would be much hotter on land and in cities. Deadly mosquito-borne illnesses such as malaria and dengue fever would spread farther. Droughts would be more likely. So would deluges. Tropical fisheries would empty further. Staple crop yields, particularly in some of the world’s poorest nations, would decline more. Disastrous loss of the Antarctic ice sheet would be more likely. Feedback loops could push warming further than anticipated, as, for example, thawing permafrost releases gases the frozen ground has trapped for centuries. Up to nearly 1 million additional square miles of permafrost would thaw at 2 degrees of warming. WHAT ARE YOU GOING TO DO?
