Where Has All the Heat Gone? Into Changing the Circulation of the Deep Blue Sea...

A century and half of reconstructed ocean warming offers clues for the future,
University of Oxford, January 7, 2019.

MAIN POINTS

Global Warming
“Over the past century, increased greenhouse gas emissions have given rise to an excess of energy in the Earth system.”

More than 90% of Heating into Oceans
“...More than 90% of this excess energy has been absorbed by the ocean...”

“...the oceans are absorbing most of the excess energy in the climate system arising from greenhouse gases emitted by human activities.”

How Much Warming
“...global warming of the oceans of 436 x 1021 Joules has occurred from 1871 to present (roughly 1000 times annual worldwide human primary energy consumption) and that comparable warming happened over the periods 1920-1945 and 1990-2015.”

Sidenote
How Much Energy
is
436 x 1021 Joules?
A Hell of a Lot
“The excess heat absorbed by the oceans in that time frame is around 1,000 times the annual energy use of the entire population of Earth...by the equivalent of one atomic bomb explosion per second for the past 150 years.”
Above from Seeker, 1-9-19

New Approach to Heat Analysis
This, “...technique to reconstruct ocean warming is based on a mathematical approach originally developed to reconstruct manmade CO2 uptake by the ocean.

Changing Ocean Circulation Patterns
“...in the last 60 years up to half the observed warming and associated sea level rise in low- and mid- latitudes of the Atlantic Ocean is due to changes in ocean circulation. During this period, more heat has accumulated at lower latitudes than would have if circulation were not changing.”

Fitting Reality
“...the consistency of the new estimate with direct temperature measurements gives the team confidence in their approach.”

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!
