Major Winter Storm headed for the US West Coast

Snow will come to California’s Sierra Nevada a bit earlier than usual.

Ryan Maue adds:  “as this storm pulls eastward, it will “bomb” out or explosively deepen over the Great Plains and move into the upper-Midwest.  The barometric pressure will fall to 962 mb 955 mb according to the most recent GFS forecast, making it one of the deepest northern United States continental extratropical cyclones since 1979 for the 30-day period between October 15 and November 14.  This will clearly be a historical storm and an extreme event: evidence of global warming La Nina.”

“The acceleration of the hydrological cycle, which seems to one of the planet’s natural reactions to this increase,”
Which would lead to stronger and more storms, right? Yeah, right. So we can’t be warming, otherwise we would have more and stronger storms. Thanks for debunking AGW in such an elegant way. We appreciate that.
Oh, BTW, can a planet have unnatural reactions? 🙂
_______
The hydrological cycle ultimately leads to the weathering of rock, which removes CO2 from the atmosphere, transporting it to the oceans. When greater amounts of CO2 are present, this cycle “accelerates” from the excess energy in the system. (You can’t get “accleration” of a system without the application of energy). This cycle in general acts over millions of years to keep the system in balance. Generally, CO2 levels keep fairly constant, or have for the time period of human civilization’s emergence. Now of course, the CO2 levels have increased 40% in just a few hundred years (virtually instantly in geological terms), and so the big question is, how sensitive is the planet to this large and rapid increase of CO2, and how will the natural hydrological cycle react to this anthropogenic “burp”of CO2? Some studies (as I linked to in my earlier post) would seem to indicate that the cycle will and has acclerated, meaning on average heavier downpours in places that get rain (think Pakistan this summer), but also increased dryness in areas that are already marginally dry.

More hand waving from the great brown noser!
What is the “velocity” of the hydrological cycle?

I can only assume then that Anthony now approves of ad hominem attacks here on WUWT. But to use the definition of the term as I understand it, I would ask: who would it be that I would be “brown nosing”?
______
What is the “velocity” of the hydrological cycle?
Of course, I know you are having your fun, but in fact there are in fact several ways to measure the “velocity” of the hydrological cycle:
1) Ocean salinity
2) Stream flows
3) Precipitation events
4) Evaporation
Then of course, “accleration” would be a measure of the changes in these on a global basis. Here’s a nice little fairly recent study on one aspect related to measurement of the acceleration in the hydrological cycle:

Interesting study recently completed relating to the topic of storms and extra-energy available and hemispheric differences:

R Gates, you need, you really need, to live next to the Pacific Ocean along the Washington, Oregon, or California coastline. If you do, you need to get out more.
Your climate change culprit is the ocean. We are under La Nina conditions. I should know. I drove through La Nina’s cold tears this morning. And me without snow tires. Why? Can’t put my snow tires on just yet. Why? It ain’t November yet (stupid ass rule that has nothing to do with conditions on the ground).
But don’t get your knickers in a bunch. Don’t wax “climate warming”, “climate change”, “catastrophic climate change”, or “climate disruption” poetic on me. It has nothing to do with CO2. It has everything to do with La Nina. Cold La Nina inspired air mixing with left over El Nino oceanic moisture translates into cold, wintry, snowy conditions (file that under “duh”).
I have to ask, do you have living grandparents? You act as if you haven’t heard the weather stories from past generations.

He won’t listen to your logic and reason, Pamela, because he is unable to do so.
Figured that one out a while back.
He is the reason NASA and the UKMet is in such a fix.
Even though he is definitely not a scientist, it is scientists of his ideological ilk that are running things in the science community, so same difference.
Its like they themselves are caught in their own runaway greenhouse effect, of sorts, where, so to speak, positive feedback is rampant, due to the human tendency toward cognitive dissonance….combined with the distasteful narcissistic homo sapiens trait of talking out of the rear.
One day open-mindedness and reason will return.

From R Gates Science Daily link on the acceleration of the hydro cycle:
“These broad-scale patterns of change are qualitatively consistent with simulations reported by the Intergovernmental Panel on Climate Change (IPCC).”
=============================
Oh…OK….consistent with the IPCC.
Wow. I am exactly anti-concerned, then.
Nothing more to be said.
