Paul,
As a former Californian who goes back most summers, Lake Shasta has been low for the last 20 plus years, at least to my eyes. I remember a lot more water in it in the late '80s.

A couple of years of low snowfall? If I were talking about snowfall records being broken the last couple of winters (such as what happened in Boston), you'd be telling me it's just weather and not climate.

Investors have a lot to learn from the California drought: It's a real-life lesson in the importance of diversification and hedging. While the drought and ensuing regulations have actually left Big Ag relatively untouched, its energy sector is undergoing a rapid revolution.Hydropower accounted for around 20% of California's in-state generation from January to July (the wet months) for the past decade. But recent data suggest that hydropower's "new normal" may be more like 10%, or perhaps even less. For the 2014-2015 winter, officials now estimate that California's snowfall clocks in at just 6% of normal rates. [my emphasis added]-------------------------------------

I'm not talking about emissions controls or fuel efficiency initiatives (both of which I think are a good idea). I'm talking about raising oil taxes to fight climate change and carbon trading schemes. The last thing you want to do in a struggling economy is raise fuel prices. The cost of *everything* goes up. People find it harder to look for jobs, they can't buy as much, etc. The economy comes to even more of a standstill. Carbon trading schemes are a joke, cooked up by energy companies to reign in coal companies so that they can make more profits on natural gas.
While I'm not a fan of Big Oil fat cats in a smoke-filled room doing... whatever it is they do in smoke-filled rooms, the simple fact is that we wouldn't be where we are technologically without easy-to-burn carbon. If we had to stick to windmills and solar heating, we would have been sunk.
Meanwhile, the one saviour of a solution (at least until we get cheap fusion) is the same one that the same people pushing carbon credits and solar power don't want you to use - nuclear power. And... we're back to the topic of people wanting to manipulate me through fear.
Anyway, if climate change is as big a danger as they make it out to be, it should become very obvious Real Soon Now. I'm not talking about "97.386% of scientists now toe the line" type studies, I'm talking about crops failing en masse and cities getting flooded. Since it's become so politicized, the only smart thing to do is to sit back and see what the climate does and assume everyone's lying to us. So far, I haven't seen anything to get worried about.

Comments like this is the basis for why the 'debate' about climate change becomes so corrupted. It's actually good for the economy when government tightens up on emissions and mandates increased fuel efficiency because it spurs on innovation and accordingly creates jobs and new industries. What's the downside...It goes against your best interest if you've invested in Shell, Chevron, Exxon Mobile, Oil ETFs, Master Limited Partnerships, etc.?

I'm not sure why I'm bothering, but for me it comes down to a desire not to be manipulated by fear as well as the desire not to be demonized for it. According to Wikipedia, we have had a temperature increase since about 1900 of 0.74 +- 0.18C. CO2 levels back then were about 280ppm, we're currently at about 400ppm. Calculate that out, and it would appear that we should expect an increase of around 1.7C for a doubling of CO2. OK, great. I'll keep that in mind over the next 80 years or so. Not nearly as high as what they are trying to scare us with. I keep an eye on sea level data at http://sealevel.colorado.edu. That first graph has been pegged at 3.2 +- 0.4 mm/yr for the last couple or more years now. Not even a hint that it will start erupting upward anytime soon. We're talking a little over a foot a century. Nothing to piss our pants about. Sea ice in the arctic continues to frustrate those who keep expecting an ice free summer. No idea what it will do this year.
Almost everything else is speculation and over-exaggeration as far as I can tell. I don't buy into the "man is killing the planet" morality play. I don't see any need to put any brakes on the economy in order to force us off of oil. If anything, we need the economy as strong as possible so we can be effective when we need to be. I don't think we should be messing with geoengineering schemes quite yet.
If things take a sudden turn for the worse, I'll rethink my position.
That's my basic take on it. I'm not interested in yet another back-and-forth exchange.
Paul
P.S. As for the possibility of religion trumping my common sense on this topic, I have no idea what spiritists / occultists think about climate change; as far as I can tell there is no position on it. Maybe all 12 of us should sit down and discuss it sometime.

Perhaps I misunderstood, or you were engaging in hyperbole for amusement...
You can't really mean to suggest that everyone who has a view on anthropogenic global warming is merely "clinging tightly to their own blind biases."
Or just the people you "hang with?"

Thus Deb makes a good point about some who "melt-down," who are denying the validity of the thousands of peer reviewed scientific studies indicating significant anthropogenic climate change is occurring, when confronted with this body of science.
But as I recently told a local climate change activist, if you want to find peer reviewed published scientific studies that question the consensus scientific view on anthropogenic climate change, they can be found. I have made a deliberate effort to study the scientific theories that indicate anthropogenic climate change is not a problem to the extent most competent scientists indicate it is...
Below are a few that have generated considerable discussion in recent years. I'll not present the scientific refutations of these published scientific papers, but refuted they were.

Nothing can be "proven beyond all doubt" technically speaking. New data or theory can always alter a given scientific consensus, though some scientists would argue this is philosophical nit-picking on some very well established theories.
But consider the millions of people who insist that the theory or evolution, insofar as it indicates homo sapiens evolved over millions of years from other species, is not a "proven" scientific theory, despite the overwhelming scientific evidence. Science is still "trumped" by religion on this issue.
Given the bias of some people, it does not matter how well "proven" a scientific theory may be... it will still be denied!---------------------------------------Vision2020 Post: Ted Moffett

The sad reality is that throughout history science has been routinely trumped by politics and religion until it can be proven beyond all doubt. And personally, I'm OK with that to some extent because the effect is that it forces very comprehensive and far reaching studies to unearth all the facts and impeach all of the fiction.
This short video is a good parallel of what happens whenever the topic of climate change comes up with either my 'global warming is a myth' friends or with my 'we are going to die because of global warming' friends:

Thanks, Ted. this is good info, and assists me when
i talk to folks with little science background and a denier agenda---you are
always on top of it! I have watched climate denier folks melt-down when
confronted with facts that refute their disbelief---even they can only suspend
disbelief until their arms hurt a bunch....and most of them don't have the

4-13-15: Ruddiman's Early Anthropogenic Climate Impact Theory
I was surprised to just today read on Realclimate.org a piece dated 13
April 2015, by climate scientist William Ruddiman, discussing how the
scientific community has received his controversial theory regarding early
(before major fossil fuel powered industrial civilization) human climate
impacts.
His Realclimate.org piece argues, and I quote, against the
alleged "censure from a nearly monolithic community intent on imposing a
mainstream view" that is sometimes claimed to exist by those critical of the
science demonstrating major human impacts on climate change.
I was particularly interested in this Realclimate.org piece because I
referenced his theory in a 2007 op-ed in the Moscow-Pullman Daily News, which
now has a Google News webpage of an actual scan of the actual op-ed page in
the Moscow-Pullman DN. How or why this scan happened I do not know, but
it can be read at the webpage below:

A Scientific Debate Filed under: Climate Science — mike @ 13 April
2015
Bill Ruddiman, University of Virginia
Recently I’ve read claims that some scientists are opposed to AGW but
won’t speak out because they fear censure from a nearly monolithic community
intent on imposing a mainstream view. Yet my last 10 years of personal
experience refute this claim. This story began late in 2003 when I introduced
a new idea (the ‘early anthropogenic hypothesis’) that went completely against
a prevailing climatic paradigm of the time. I claimed that detectable human
influences on Earth’s surface and its climate began thousands of years ago
because of agriculture. Here I describe how this radically different idea was
received by the mainstream scientific community.
Was my initial attempt to present this new idea suppressed? No. I
submitted a paper to Climatic Change, then edited by Steve Schneider, a
well-known climate scientist and AGW spokesman. From what I could tell, Steve
was agnostic about my idea but published it because he found it an interesting
challenge to the conventional wisdom. I also gave the Emiliani lecture at the
2003 December American Geophysical Union (AGU) conference to some 800 people.
I feel certain that very few of those scientists came to my talk believing
what my abstract claimed. They attended because they were interested in a
really new idea from someone with a decent career reputation. The talk was
covered by many prominent media sources, including the New York Times and The
Economist. This experience told me that provocative new ideas draw interest
because they are provocative and new, provided that they pass the key ‘sniff
test’ by presenting evidence in support of their claims.
Did this radical new idea have difficulty receiving research funding? No.
Proposals submitted to the highly competitive National Science Foundation
(NSF) with John Kutzbach and Steve Vavrus have been fully funded since 2004 by
3-year grants. Even though the hypothesis of early anthropogenic effects on
climate has been controversial (and still is for some), we crafted proposals
that were carefully written, tightly reasoned, and focused on testing the new
idea. As a result, we succeeded against negative funding odds of 4-1 or 5-1.
One program manager told me he planned to put our grant on a short list of
‘transformational’ proposals/grants that NSF had requested. That didn’t mean
he accepted our hypothesis. It meant that he felt that our hypothesis had the
potential to transform that particular field of paleoclimatic research, if
proven correct.
Were we able to get papers published? Yes. As any scientist will tell
you, this process is rarely easy. Even reviewers who basically support what
you have to say will rarely hand out ‘easy-pass’ reviews. They add their own
perspective, and they often point out useful improvements. A few reviews of
the 30-some papers we have published during the last 11 years have come back
with extremely negative reviews, seemingly from scientists who seem deeply
opposed to anything that even hints at large early anthropogenic effects.
While these uber-critical reviews are discouraging, I have learned to put them
aside for a few days, give my spirits time to rebound, and then address the
criticisms that are fair (that is, evidence-based), explain to the journal
editor why other criticisms are unfair, and submit a revised (and inevitably
improved) paper. Eventually, our views have always gotten published, although
sometimes only after considerable effort.
The decade-long argument over large early anthropogenic effects
continues, although recent syntheses of archeological and paleoecological data
have been increasingly supportive. In any case, I continue to trust the
scientific process to sort this debate out. I suggest that my experience is a
good index of the way the system actually operates when new and controversial
ideas emerge. I see no evidence that the system is muffling good new ideas.
