"WASHINGTON — The world continues to increase the amount of heat-trapping carbon dioxide it pumps into the air, but it’s not rising as fast as in the previous couple years.
Led by big jumps from China and India, the world is projected to spew 40.57 billion tons (36.8 billion metric tons) of carbon dioxide into the air in 2019. That’s up nearly 255 million tons (231 million metric tons) from 2018, according to two scientific studies released Tuesday. The studies by Global Carbon Project, a group of international scientists who track emissions, show a 0.6% increase from last year.
In previous years, global carbon dioxide emissions grew by 2.1% and 1.5% after a few years in the mid 2010s when global emissions barely rose, according to the studies in Environmental Research Letters. Carbon dioxide from the burning of coal, oil and gas has caused 1.8 degrees of warming (1 degree Celsius) since pre-industrial times and world leaders are meeting in Madrid to try to limit warming to another 1.8 degrees from now."
