  • As of Wednesday, the McBride Fire in New Mexico has burned 6,159 acres and is 89% contained.
  • Billowing black smoke during wildfire disasters has caused atmospheric carbon monoxide levels to increase.
    • Wildfires raging across the west can impact the air locally and afar, with the potential to affect millions across the country. 
    • The toxic output from fires is dangerous, contributing to an estimated loss of more than 15,000 lives in the US each year. Some scientists say that number will double by the end of the century.
    • Smoke from western fires has also been attributed to up to 5,900 asthma-related emergency department visits a year.

Extreme Heat

  • The Colorado River earned the title of “most endangered” waterway in the nation in 2022.
    • That Colorado River basin, which spans seven Western states and Mexico, is in the midst of a 20-year drought, as warming temperatures and aridification have sharply reduced its water supply.
  • Utah’s Governor Spencer Cox warned a new state of emergency for drought is likely this year.
  • The “Excess Urban Heat Mitigation Act of 2022,” from Rep. Ruben Gallego (D-Ariz.) would create a competitive grant program to fund projects by local governments, metropolitan planning organizations, and nonprofits that address extreme heat.
    • The $30 million grant program would fund projects like lighter-colored pavement and roofs that can reflect heat, tree planting, bus stop covers, cooling centers, and heat mitigation education.
    • The bill would mandate that at least 50% of funding go toward projects in low-income and environmental justice communities.
  • Scientists have found that natural climate cycles and human-caused climate change are the reason for Antarctic sea ice hitting a stunning record-low minimum at the end of February, dropping below 772,000 square miles.

New Reports And Data

  • An April 2022 study found that billowing black smoke during wildfire disasters has caused atmospheric carbon monoxide levels to increase.
  • An April 2022 study found how fine air pollution particles might cause lung cancer.
  • An April 2022 study found that natural climate cycles and human-caused climate change are to blame for Antarctic sea ice hitting a record low minimum.
