Climate Emergency: Earth's Ecosystems at Tipping Point

Earth's weather systems are becoming increasingly disrupted and destructive due to the high levels of carbon dioxide and greenhouse gases in the atmosphere. Scientists warn that we are moving into dangerous territory, with devastating heat waves and high sea temperatures leading to concerns about the collapse of vital ocean currents. There is a debate among experts about the pace of global heating, and a new study suggests that a tipping point may be approaching. The oceans, which have absorbed 90% of the heat trapped by greenhouse gases, are now experiencing record-breaking temperatures and changes in color.
