The landscape is the proof, and the landslides, and the shrinking snow pack, too.

That and California and the entire southwest of the USA will run out of water. Lake Meade (behind the Hoover Dam) will go too low to supply water very soon.

2" / hour rains in California, causing landslides,
Landslides are likely because of huge wild fires,
Huge wild fires are common because of droughts,
Droughts are happening because the snow pack is shrinking,
Snow packs are shrinking because of lots of heat: both in the summer AND because it is warm enough to rain in the winter *instead* of snowing...

Hmmm...

So, were confused Neil.
Are you saying the drought is caused by GCC or the floods are from GCC ?
You gotta pick one.

The earth goes through cycles, back around the 20s and 30s people were saying coal was causing an ice age to start due to pollution blocking the suns warmth.


So, just what is the ideal ocean PH/earth temp/water:ice ratio ?

Nah, don't expect him to pick one. The reason the movement was clever enough to change the name from "Global Warming" to "Climate Change" is so that no matter what happens they can declare that it proves their ideology right. Floods here, drought there - it's all caused by those damn humans and their destructive technology that is raping the eaarth. First we'll regulate industry, then we'll outlaw it. We'll cloak ourselves in the mantle of "saaving the plaanet" and always pretend there is no underlying political motive to it.

They want a 'goldilocks' climate - not too hot, not too cold. (Of course natural cycles and extremes in weather cannot be controlled that way - but we're not supposed to notice or mention that.) And no matter how tepid it becomes they will always have a rationalization to impose more regulation.

It amounts to a coin toss where 'if it's heads I win, if it's tails you lose'.

...a quote that any politician would've been proud to author (ha,ha)!

Guys, it is both. More heat energy means more evaporation, and more melting, and more winds, and bigger storms. This brings changes to the weather patterns, and some places get more rain, and some places gets more drought.

If in CA, there is normally snow, that builds up as snow pack, and that snow pack melts during the summer, providing water. But, if instead it comes down as rain -- a lot more rain, this causes flooding and landslides now; and later in the summer since there is much less snow to melt, you get a drought.

Add to this, you are also getting more lightning, and during droughts, you get more fires, which wipes out vegetation -- then when you get a lot of rain all at once, you can get landslides.

It is very different to get 15 inches of rain slowly during the year, than it is to get 35 inches all in a couple of months.

This is what is happening around the world. More droughts and more rain, bigger storms, and more lightning, more snow where there didn't used to be much snow, and higher temperatures, with more water vapor, acidifying oceans, melting glaciers, and glacier fed rivers will diminish, forests are dieing, etc., etc.

...

Would it be correct to state that the weather system is in flux as the overall temperature increases over time? It is both because the weather system is being effected and adapting to the change.

Assuming it's inevitable I have been crossing my fingers that Southern California will benefit from GCC because our weather pattern could eventually stabilize as wetter, ala the NorthWest.

Sorry for being a little slow, GCC wasnt taught in my physical engineering classes.

Explain again how an increase in temperature creates more snow ?

And explain too how the Sun's varying output somehow does not cause variations in weather.

It does cause variations in weather. Increased solar activity causes increased temperature and decreased solar activity oddly enough causes increased hurricane activity. We are currently near the end of a solar minimum, which could partially explain increased hurricane strength of the last decade (though since weather is very complex there could be other factors as well.) Overall temperature should have cooled over 2000-2009 because of decreased solar activity but is was actually the hottest decade on record, globally.

Increased ocean temperature means more evaporation. When that water comes back down, if the air temperature is below freezing it is snow/ice, if the air temperature is above freezing it is rain.

Climate is long term; weather is short term.

Lots of rain (6 months worth in less than a week) is different than it has been -- a data point showing possible long term change.

The snow pack is the source of water in the summer, and if the snow pack is melting faster than it is built up, then that is another data point showing possible long term change.

If the small amount of rain that normally come all through the year stops happening, then you get a drought; then that is another data point showing possible long term change.

There is more lightning now, and there is more water evaporation, and there are stronger storms more often. So, when rain does happen, it is far more intense more of the time than it used to be; and this is another data point showing possible long term change.

More lightning with more drought, then you get more and larger wildfires, and this weakens the landscape's ability to absorb the rains, which are stronger than they normally are, so you get more landslides; which is another data point showing possible long term change.

New and different patterns, with more or less precipitation and at different times than what was normal -- is the new normal. In other words, things have changed.
