Skip to comments.Odds that global warming is due to natural factors: slim to none [GIGO}
Posted on 04/12/2014 7:01:26 PM PDT by BenLurkin
To assess the natural variability before much human interference, the new study uses multi-proxy climate reconstructions developed by scientists in recent years to estimate historical temperatures, as well as fluctuation-analysis techniques from nonlinear geophysics. The climate reconstructions take into account a variety of gauges found in nature, such as tree rings, ice cores, and lake sediments. And the fluctuation-analysis techniques make it possible to understand the temperature variations over wide ranges of time scales.
For the industrial era, Lovejoys analysis uses carbon-dioxide from the burning of fossil fuels as a proxy for all man-made climate influences a simplification justified by the tight relationship between global economic activity and the emission of greenhouse gases and particulate pollution, he says. This allows the new approach to implicitly include the cooling effects of particulate pollution that are still poorly quantified in computer models, he adds.

I have the text of the computer simulation right here:
print "It's Global Warming!"
Yeah, we know just like the world food shortage, Peak oil and acid rain. And what all else. Socialism masquerading as environmentalism.
Dangit, not another headache. Oh well, back to FR.
Somebody been hittin’ da happy smoke.
Anthony Watts has a summary of this paper, a link to a rebuttal, and some choice comments over at Watts up with that:
Odds that the globe is warming significantly: slim to none.
There are an astounding number of factors that they deliberately ignore, I don’t know how they can take themselves seriously.
Don’t tell them that another 5% closer to the sun and we’ll be out of the habitable zone. They’ll be looking for ways to move the earth away.

You know summer is coming when climate change becomes global warming.
What caused the Ice Age? Why did the ice later melt?
ANYTHING that The Mann has touched is totally bogus.
Oh it must be right because NEVER before in all of recorded history have we experienced global warming or cooling...That mini ice age in the 1700s was all made up and imaginary. Only now are we lucky enough to have one such as Al Gore to tell us the truth.
Was that snarky enough?
I would put the sun and volcanos at the top of the list, but then I’m not a climate scientist.
So how did the Medieval and Roman warming periods happen?
You nailed it morphing! Sun’s effect dwarfs any human factors, but if there is a second influence, volcanic ash would be a strong candidate. The Iceland volcanoes spilled thousands if not millions of times as much particulate matter into the atmosphere in a single year as all of human activity ever did. Media ignoring that, of course.
now I could be wrong, but I’m fairly certain all the global warminig comes from the sun and last i checked, the sun is considered ‘natural’
of course, the flaming libtards know better... via their drug induced haze... so maybe they should babble on some more
oh, I’ll never endorse ANY money for their ‘research’ but they’re more then welcome to babble away
George Bush caused it. He did it in Texas with a fracking...thing
Love Watts. The comments are great too. David l. had it exactly correct when he quoted Rutherford
