The Fossil Fuel Industry Continues Producing Heat-Trapping Emissions that Drive Climate Change

Union of Concerned Scientists

The InfluenceMap dataset includes company-by-company data on emissions of carbon dioxide–the heat-trapping gas responsible for the largest contribution to climate change–and methane, a very potent heat-trapping gas that lasts a shorter time in the atmosphere.

What Is Vapor Pressure Deficit (VPD) and What Is Its Connection to Wildfires?

Union of Concerned Scientists

Foundations of vapor pressure deficit Two principles of physics are key to understanding VPD and how it interacts with our ecosystems and atmosphere, which ultimately affect fire risk. When plants perform photosynthesis, they open their pores to exchange oxygen for carbon dioxide.

New, Updated Carbon Majors Dataset Holds Promise for Researchers, Litigators

Union of Concerned Scientists

That 2013 headline resulted from the first effort to quantify emissions from the ‘carbon majors’ —fossil fuel companies and cement manufacturers whose businesses have contributed an outsized amount of heat-trapping gases to the atmosphere.
