Not to alarm you, but scientists say four of Earth’s big climate systems—the Greenland Ice Sheet, Atlantic currents, the Amazon rainforest, and the South American monsoon—are all showing signs of failing. Each one helps keep the planet stable, but if one tips, it could set off a global chain reaction. Basically, our planet’s safety nets are fraying, and the warning signs are getting harder to ignore. Time to pay attention before these dominoes really start to fall! #Science #ClimateCrisis #EarthSystems
