Data analyst Zoe Phin here looks at what the data from the USCRN? has been indicating in terms of a temperature trend over the past 15 years. The USCRN is a network of stations deployed across the continental U.S.
USCRN data are here.
Here’s the air temperature trend at USCRN stations over the last 15 years? (4/2007 – 4/2022), Zoe has found:
Some points:
- Alaska stations show some warming
- New England has been cooling
- The upper Midwest and Great Plains are cooling as well
In fact: “Only 23 out of 98, that is, ~23.5% show a warming trend,” Zoe finds.
Surface temperature tumbles
The results are even cooler when it comes surface temperature measured at the 92 sites with persistent IR surface data:
Here, Zoe computed a total 15-year average cooling of about 1.26 °C going back to April, 2007. Breakdown at her site.
“Only 11 out of 92, that is, ~12% show a warming trend,” she finds. “Now this is important: I’m not saying that the US has cooled over the last 15 years. All I’m saying is that the newest and best stations suggest this. You decide the significance of this.”
