“A new study led by Nadine Unger of NASA’s Goddard Institute for Space Studies (GISS) in New York City offers a more intuitive way to understand what’s changing the Earth’s climate. Rather than analyzing impacts by chemical species, scientists have analyzed the climate impacts by different economic sectors.
In their analysis, motor vehicles emerged as the greatest contributor to atmospheric warming now and in the near term. Cars, buses, and trucks release pollutants and greenhouse gases that promote warming, while emitting few aerosols that counteract it.”
