The Earth has warmed an average of 1.1 degrees Celsius (1.9 degrees Fahrenheit) since the Industrial Age largely because of human activity, namely the burning of oil, gas and coal. Scientists say that every fraction of a degree of heating translates into more frequent droughts, more violent storms, more species extinction — impacts that are already being felt in every corner of the globe. Once the Earth passes a threshold of 1.5 degrees of warming (2.7 degrees Fahrenheit), the likelihood of devastating heat waves, drought, wildfires and storms rises significantly, scientists say.
Brenda Mallory, the chair of the White House Council on Environmental Quality, reminded the crowd about steps the Biden administration has taken to cut pollution. But she emphasized the need to pass his stalled legislation, which would provide more than $500 billion in tax credits designed to speed the country’s transition to wind and solar power as well as to electric cars.
“President Biden will use every lever, use every tool, and push every resource to tackle climate change,” she said. “But Congress must act, too.”
Mr. Simpkins has followed Mr. Biden’s actions, including a crackdown on planet-warming methane that leaks from oil and gas wells and a ban on hydrofluorocarbons, a greenhouse gas produced by refrigerator coolants.
