Extreme Heat Expanding with The End of Cold

Extreme heat increasing in both summer and winter,
American Geophysical Union, November 26, 2018.

MAIN POINTS

Hotter Hots-Warmer "Colds"
“A new study shows extreme heat events both in the summer and in the winter are increasing across the U.S. and Canada, while extreme cold events in summer and winter are declining.”

Scope of Study
“...examined absolute extreme temperatures--high temperatures in summer and low temperatures in winter--but also looked at relative extreme temperature events--unusually cold temperatures and unusually warm temperatures throughout the year.”

Extreme Heat Rising Radically
“...both relative and absolute extreme heat events have increased across the US and Canada since 1980. This upward trend is greatest across the southern US, especially in the Ozarks and southern Arizona, as well as northern Quebec. That means there are more extremely hot days during the summer as well as more days that are considered extremely hot for the time of year, like abnormally warm days in the winter.”

A Greater Danger
“...temperature extremes pose a greater ecological risk to many species than average warming.”

The Greater Danger
“...one of the first to explore relative extreme temperature events, which are changing more rapidly than absolute temperature extremes, and can have important implications for the environment, agriculture and human health.”

“...we've also seen that extreme temperatures that are really anomalous for the time of year can have a high impact--these relative extremes are important and underappreciated,"

Time Scale
“...how they have changed from 1980-2016.”

The New Abnormal
“Relative extreme temperature events are changing faster than absolute extreme events, and often occur outside of seasonal norms...”

“Out-of-season extreme temperatures can cause early thaws in mild winters or catch vulnerable populations unprepared and unacclimated.”

Not Extreme Arctic
“Across parts of the Arctic, extreme cold events have become almost entirely nonexistent and increasingly difficult to identify, according to the researchers.”

Phrenology Probs
"Relative temperature anomalies can trigger what are called phenological mismatches, where a mismatch in the temperature and the season can cause trees to bloom too early and birds and insects to migrate before there is appropriate food."

 

The End of Cold

This increase in Winter Temperatures has been happening for a long time, in lockstep with the increase in the length and temperature of Summer. I began noticing declines in the snowpack as the brush began sticking above the snowpack, where and when it had traditionally been buried under the Winter snowpack, in the High Sierra, during the mid-90’s.

Support Tahoe to Whitney

The Tahoe to Whitney Trail Guide and Magazine are walked, written, funded, and supported by my efforts, with the help of kindred spirits and my sister.

We offer valuable Trail Guide, Skills, Weather, News and Analysis.

My goal is to get you out to see your natural and social potential. Help me keep this unique resource accessible and expanding towards its potential. We've a lot of miles to cover ahead...

I NEED HELP!
If you feel these efforts are valuable, I'm cordially inviting you to support them, here:

 

 

I am currently working towards publishing the completed guide between Tahoe & Yosemite as an e-book, while converting this "blog" to a fine magazine format. You will like the results! Help Tahoe to Whitney reach its potential!
