Melting Southern Continent Delivers Global Climate & Ocean Surprises

Antarctic melting slows atmospheric warming and speeds sea level rise,
University of Arizona, November 19, 2018.


Melting Ice Effect
“...first to project how the melting of the Antarctic ice sheet will affect future climate...current climate models do not include the effects of melting ice on the global climate.”

"No one had looked at the big picture of what Antarctic ice sheet melting means for the global climate."

“...the research team modified one of the most current climate computer models to include the ice melt.”

“...they set the level of greenhouse gas emissions for the 21st century using the scenario known as RCP8.5, sometimes called the "business-as-usual" scenario.”

Delays Air Warming, Accelerates Rising Oceans
“As the Antarctic ice sheet melts, warming of the atmosphere will be delayed by about a decade but sea level rise will accelerate...”

“...the team's new research reveals that the additional freshwater from the melting ice sheet acts like a lid on the waters around Antarctica and slows the release of heat.”

"Warming won't be as bad as fast as we thought, but sea level rise will be worse."

Ten Inches More Ocean
“...found that by the year 2100, sea level could rise as much as 10 inches more than the previous estimate of approximately 30 inches by 2100.”

12 More Years to Reach 2 Degree Temp Increase
“Adding the melted ice into the team's model indicated that the global temperature would increase by 2 degrees C (3.6 F) by the year 2065, rather than the year 2053.”

“'s still warming but it will warm less steeply and give us another 15-year grace period.”

Tropical Precipitation Shifting Further North
“…the tropical rain belt will shift north...”

"Our projections indicate the tropical rain belt will shift toward the Northern Hemisphere, making it slightly wetter in the Northern Hemisphere and slightly drier in the Southern Hemisphere than previously predicted,.

“...surprised by their findings. They did not expect the Antarctic meltwater to affect the global climate system.”

The Frontier of New Knowledge
"It's the first new identified feedback on climate in 20 years."

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...

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!
