THREAD: Are you ready for this week’s heat? Are you ready for it to be the norm? Check out how this week’s forecast stacks up against this century’s #ExtremeHeat projection for your town and learn what’s at stake without climate action with our heat tool: act.ucsusa.org/HeatTool

According to our new study, #KillerHeat is only going to get worse. We are projecting how the heat index, or “feels like” temperature, will likely change in your town by the middle of the century with no action to reduce global warming emissions. ucsusa.org/KillerHeat

By late century, our #KillerHeat report projects that with no action, some areas will endure four months a year when the “feels like” temp will exceed 105°F. BUT, rapid bold action can drastically curb these extreme heat days. #ActOnClimate

Tampa’s feels like temp 🔥
This week: expected 5 days of 100+°F
Midcentury w/out climate action: 123 days per year of 100+°F
Late century w/out climate action: 155 days per year of 100+°F
Historically (1971-2000): 30 days per year of 100+°F

We also found that #KillerHeat could “break” the @NWS heat index by leading to widespread off-the-charts heat days (temperature and humidity that, combined, exceed the NWS calculable heat index values) even by mid-century. Late century shown here.
