Climate Impact Report – 08/17

Quick Facts

Water Cuts

For the second year in a row, Arizona and Nevada will face cuts in the water they can draw from the Colorado River as the West endures more drought.

425,000

Since October, more than 425,000 people have discontinued their coverage from FEMA’s National Flood Insurance Program after FEMA began to raise rates on millions of properties to reflect flood risk more accurately.

Form Early

An August 2022 study found that Atlantic hurricanes are actually forming earlier over time as the ocean warms.

Extreme Heat

  • Hot weather is expected again Wednesday and Thursday in western Oregon and Washington state. 
    • Multnomah County, which includes Portland, will offer people places to stay cool Wednesday as temperatures potentially reach 100 degrees Fahrenheit.
    • The National Weather Service says overnight lows are expected to stay near 70 degrees, offering little relief.
    • A heat advisory has also been issued for the Puget Sound region in Washington state from Wednesday afternoon through Thursday at midnight, with temperatures expected to be in the 90s.
    • An excessive heat warning will also be in effect for areas along the Cascade foothills from the Washington border with Canada south to Lewis County in southwest Washington, where temperatures could reach 100 degrees. 
  • For the second year in a row, Arizona and Nevada will face cuts in the water they can draw from the Colorado River as the West endures more drought.
    • Arizona will lose an additional 80,000 acre-feet of water — 21% less than its total share but only 3% less than what it’s receiving this year.
      • An average household uses one-half to one acre-foot of water a year.
      • State officials said this year’s cuts would extend to tribes and growing cities that rely on the Colorado River, including Scottsdale.
    • Nevada also will lose about 8% of its water supply, but most residents will not feel the effects because the state recycles most of its water indoors and doesn’t use its full allocation.
    • Because the states failed to meet a federal deadline to figure out how to cut their water use by at least 15%, they could see even deeper cuts that the government has said are needed to prevent reservoirs from falling so low they cannot be pumped.
    • The water level at Lake Mead, the nation’s largest man-made reservoir, has plummeted so low that it’s currently less than a quarter full and inching dangerously close to a point where not enough water would flow to produce hydroelectric power at the Hoover Dam on the Nevada-Arizona border.

New Reports And Data

  • An August 2022 study found that residents of some of the highest-risk U.S. counties for heat exposure have the lowest levels of concern about climate change.
