New research indicates likely hydrological implications of rapid global warming,

Paleocene Eocene Thermal Maximum

50 million years ago

"From records of the PETM, like this one, it has become very clear that global warming causes major changes in the patterns and intensity of rainfall events. These changes are so large that we see evidence of them in the geological record, as a many-fold increase in the mass of sediments transported from land to the oceans. This has the potential for profound impacts on shallow marine ecosystems, and that is exactly what we see at the PETM."


"The associated period of massive carbon injection into the atmosphere has been estimated to have lasted no longer than 20,000 years. The entire warm period lasted for about 200,000 years. Global temperatures increased by 5–8 °C. The carbon dioxide was likely released in two pulses, the first lasting less than 2,000 years. Such a repeated carbon release is in line with current global warming."

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!
