Extreme Temperature Diary- Wednesday April 20th, 2022/Main Topic: Counting Down to Earth Day…New Climate Central Warming Statistics

The main purpose of this ongoing blog will be to track planetary extreme, or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉

Main Topic: Down to Earth Day…New Climate Central Warming Statistics

Dear Diary. My how time flies. It seems like yesterday that I was writing my annual post for Earth Day 2021, and we are about to see Earth Day 2022 on the 22nd of this month. Earth Day has been a special day for all environmentalists trying to protect the health of our planet so that both it and all flours and fauna, including us humans, will live on a bright, green planet for myriads of generations to come.

This year I’ll be celebrating the lead up to Earth Day on not one but three posts. For the first post let’s see how much the United States has warmed since the first Earth Day in 1970 because of greenhouse gas pollution, using fresh statistics calculated by Climate Central released today:

Earth Day: U.S. Warming Rankings

APR 20, 2022

Ahead of Earth Day, we’re taking stock of widespread warming in 246 U.S. locations, 49 states, and the nation since 1970.

KEY CONCEPTS

  • The U.S. has warmed by 2.6°F since the first Earth Day was celebrated on April 22, 1970.
  • 49 states and 99% of 246 U.S. cities analyzed by Climate Central have warmed since 1970. 
  • The fastest-warming city was Reno, Nev. and the fastest-warming state was Alaska. 
  • Continued warming can harm people and the planet, but there are many ways to cut heat-trapping emissions from energy, transportation, agriculture, and more.  

Warming at all levels

U.S. Warming since 1970

Happy Earth Day! 
Since the first Earth Day 52 years ago, environmental science, policy, and public awareness have transformed in the U.S. and around the world. Earth Day is a time to celebrate this progress and take stock of current challenges—including climate change. 

The concentration of heat-trapping CO2 in the atmosphere has increased nearly 30% since the first Earth Day in 1970. And when CO2 increases, temperatures follow suit. How has rising CO2 affected temperatures in the U.S.?

Widespread U.S. warming since the first Earth Day. 
Climate Central analyzed trends in annual average temperature in 246 locations, all 49 states (Hawaii was excluded; see methodology), and the entire nation since 1970 and found that:

  • The U.S. is 2.6 °F warmer today than it was in 1970. 
    • For context, 2.6 °F is very close to the global warming limit of 2.7 °F (1.5 °C) that 196 countries, including the U.S., have agreed to pursue. 
  • All 49 states analyzed have warmed by at least 1.8 °F since the first Earth Day. 
    • Alaska was the fastest-warming state by far, due to its high latitude. Melting glaciers and permafrost are contributing to sea level rise and greenhouse gas release. 
  • 99% (244) of 246 U.S. cities analyzed have warmed since 1970. 
    • 69% (170) of locations have experienced at least 2 °F of warming.
    • Many of the fastest-warming locations were in the Southwest—a region vulnerable to droughts and heat extremes, which are likely to worsen with climate change. 

The fastest-warming U.S. cities and states based on the increase in annual average temperature since 1970 were:

Fastest-warming cities (°F)Fast-warming states (°F)
Reno, Nev. (+7.7°)Alaska (+4.3°)
Las Vegas, Nev. (+5.9°)Delaware (+3.5°)
El Paso, Texas (+5.1°)New Mexico (+3.5°)
Erie, Pa. (+4.7°)New Jersey (+3.4°)
Tucson, Ariz. (+4.6°)Arizona (+3.3°)
Chattanooga, Tenn. (+4.6°)Rhode Island (+3.2°)
Burlington, Vt. (+4.5°)Massachusetts (+3.2°)
Phoenix, Ariz. (+4.3°)Connecticut (+3.2°)
McAllen, Texas (+4.1°)Utah (+3.0°)
Helena, Mont. (+4.1°)Vermont (+3.0°)

Curbing emissions to celebrate Earth. 
Warming is one of many ways that continued emissions of heat-trapping gasses like CO2 impact our planet, our communities, and our food and water supplies. 

Recent IPCC reports review the escalating impacts of climate change on people and nature, and assess ways to limit global warming and minimize further harm to people and the planet.

These scientific reports make clear that staying within the globally-agreed warming limit of 3.6 °F (2 °C) will be an immense challenge—but that the benefits of limiting warming would likely outweigh the costs of mitigation. These reports also make clear that climate solutions already exist for every major economic sector—including energytransportation and agriculture.

METHODOLOGY

Local analyses used 1970-2021 data from the Applied Climate Information System. State and U.S. temperature data were obtained from NOAA/NCEI’s Climate at a Glance. A state trend for Hawaii was not calculated because it is not included in the NOAA/NCEI dataset. Trends are based on a mathematical linear trend line, beginning in 1970 for consistency between all 247 stations. However, for data summaries based on linear trends, only 246 stations are included due to large data gaps in Wheeling, W. Va.
