About our analysis

  • Use temperature and humidity

to calculate heat in index

  • High-resolution climate models
  • Three future emissions

“We have seen a huge spike in ER visits and admissions…in the past several

  • weeks. Huge.

We have been admitting people left and right.”

About the Heat Index

For Example: 90⁰F and a relative humidity of 60%, the heat index is 100 ⁰F.

Unprecedented heat late century (2070-2099): Off the charts

  • Historically only affected

the Sonoran Desert region for a couple days per year

  • > 60% of the US (by area)

would experience these conditions at least 1x per year.

Unprecedented heat late century (2070-2099): Off the charts

  • Historically only affected

the Sonoran Desert region for a couple days per year

  • > 60% of the US (by area)

would experience these conditions at least 1x per year.

  • 120 million people would

experience 7+ days of off- the-charts heat in an average year compared with <2,000 people today.

Good News?

slide-34
SLIDE 34

Taking action now would limit expansion of heat

slide-35
SLIDE 35

Takeaways

  • Failing to take action to reduce emissions

would lead to a staggering expansion of dangerous heat.

  • Aggressively reducing emissions could

contain that expansion.

  • The time to act is now.

Renewable electricity standard

  • ↑ renewable electricity from

18% in 2018 to at least 50% in 2035

  • Nearly eliminate coal & reduce

natural gas by 38%

  • ↓ power sector CO2 emissions

46% in 2035

  • = $34 billion in savings to

consumers energy bills between 2020 and 2035

Congressional district fact sheets (433): What you can do

1) Reach out on social media. 2) Follow your representatives’

  • r other public figures’

Facebook pages or Twitter accounts. 3) Attend a members’ forum or event. 4) Write a letter to the editor for your local paper.
