And yet temperatures are cooler
The amount of heat-trapping carbon dioxide in the atmosphere averaged more than 400 parts per million globally for the first time ever in March, according to U.S. government measurements. The recording was based on air samples taken from 40 sites around the world, the National Oceanic and Atmospheric Administration said in a statement Wednesday. It’s the highest level of the gas in at least a million years. Increasing CO2 emissions are blamed for global climate change that causes stronger storms, melting Arctic ice and rising sea levels, according to scientists.
