Nations around the world still aren’t doing nearly enough to limit greenhouse gas emissions that cause global warming the report warns. While progress is being made the report says that collectively countries aren’t on track to contain global warming to the level set by leaders in the Paris Climate Agreement. We are currently on course to see between 3 and 3.2 degrees Celsius, or about 5.8 degrees Fahrenheit, of warming by the year 2100. To put this another way, countries have only committed to about one-third of the emissions reductions needed to meet the Paris Agreement’s temperature target. Such a rapid and sizable temperature increase would lead to dangerous changes in the climate, from the rapid melting of polar ice sheets, rising sea levels that could swamp coastal cities worldwide, to more frequent and extreme heat waves, wildfires, and heavy precipitation events.
