Climate change is already making parts of the world unlivable

“Global average temperatures have already risen by 1.1 degrees Celsius, roughly 2 degrees Fahrenheit, leaving perilously little room for meeting the targets of the 2015 Paris climate agreement. The accord set a goal of limiting global warming to less than 2 degrees Celsius/3.6 degrees Farenheit compared to average temperatures before the industrial revolution in the 1800s. The agreement also set a more ambitious target of staying below 1.5°C/2.7°F.

Global warming has already raised global sea levels by 9 inches. It has left a distinct mark on extreme weather too, worsening heat waves, storm surges, and rainfall. Scientists can even quantify how much human-linked emissions of heat-trapping gases have made these events worse.”

“The natural world is passing some of the hard limits of what it can handle from climate change right now, leading to irreversible changes like extinction of species. “Ecosystems already reaching or surpassing hard adaptation limits include some warm water coral reefs, some coastal wetlands, some rainforests, and some polar and mountain ecosystems,” according to the report. Humans who are dependent on these ecosystems are deeply affected as well.”

“Sea level rise is forcing residents of small islands to permanently evacuate. At least five islands in the Pacific Ocean have been lost to higher water levels. Rising temperatures are changing rainfall patterns and melting snowpacks, limiting freshwater for drinking and agriculture. This is driving migrations around the world.”

“As bad as the situation is right now, climate change can still get much worse. Rising temperatures mean that many more areas of the world, spanning some of the most populated regions, will experience times when it’s too hot to survive.”

“More than 150 million people currently live on land that will be below the high-tide line by 2050.”
