The findings are outlined in three new papers published in Earth System Science Data , Environmental Research Letters , and Nature Climate Change. The decline of coal use in the European Union and United States is overshadowed by surging natural gas and oil use around the world, according to the researchers.

A key objective of this model inter-comparison project is to understand which insights are robust across models and scenarios and which are more sensitive. The policy scenarios impose different designs of a carbon tax in the United States. Weyant (2018) Climate Change Economics. Change Econ. Fawcett, J.

Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new work led by the National Center for Atmospheric Research (NCAR). These gases come from human activities such as combustion of coal and oil as well as natural sources such as emissions from plants.
