The oceans are the key. Warm ocean water gives off CO2 while cold ocean water absorbs CO2. When temperatures rise, the average temperature of the oceans will slowly begin to rise as well and at a certain level, all the oceans become a net emitter of CO2. That accounts for the time lag. Similarly, when average ocean temperatures fall below that certain level, then the net impact on CO2 is absorption and CO2 levels fall.
I've done my homework. Have you?
Stunning: NASA GISS Admits No Evidence of AGW In The US, Won’t Be For Decades!
It is amazing what you find when you pull back the PR spin from public facade of the AGW crowd and they become honest about the global warming canard. In my previous post I discovered Jim Hansen of NASA GISS noting the US temperature data is so noisy (yet it is the most accurate, most measured in the world) that you cannot pull any conclusions from it, and basically the 1930′s and 2000′s are statistically the same temperature!
I thought that was a pretty stunning admission. Until I read further into the email trail up and Judicial Watch (page 71 of 215) and discovered this....
But I pride myself on having an open mind so how about this?
If you can find an article written by a climate scientist, that can explain why global temperatures started falling several times in the past, even as CO2 levels continued to rise for a minimum of 400 years, AND why that mechanism won't happen this time around too, then I'll seriously reconsider my position.
The orbital forcing is, however, relatively weak when considered on an annual globally averaged basis (the total insolation received by Earth has varied by < 0.7 W/m2 over the past 160 kyr).
The discovery of significant changes in climate forcing linked with the composition of the atmosphere has led to the idea that changes in the CO2 and CH4 content have played a significant part in the glacial-interglacial climate changes by amplifying, together with the growth and decay of the Northern Hemisphere ice sheets, the relatively weak orbital forcing and by constituting a link between the Northern and Southern Hemisphere climates.

CHANGE.ORG: Thorium: Nuclear Energy's Clean Little Secret
...In the 1950s and 1960s, U.S. scientists turned their backs on thorium, a cleaner alternative to uranium-fueled nuclear energy, because uranium produces plutonium as a byproduct. And plutonium is the key ingredient in nuclear bombs necessary to blast the Russians to smithereens....
Let's review some of the key benefits of thorium. It's abundant (because we've never used any of it); it doesn't require the costly and time-intensive refining process important for uranium, and the waste it produces becomes inert in one hundred years as opposed to hundreds of thousands of years. It's nearly impossible for terrorists to manipulate for weapons production. There's more: the annual fuel cost for a one gigawatt thorium reactor is approximately six hundred times lower than that of a uranium reactor, which requires 250 times more of the raw element....
Ok, if we buy your argument, then please tell me what mankind is doing to heat up the other 2?

This has been debunked so many times.
If it is indeed the sun warming up planets, then all the planets would be warming up, not just 3 of them.
The highest peak of CO2 was 300 ppm. In the next ten years we will reach 400ppm. Hardly natural.
Actually that very reason that CO2 caused or ended the ice ages.
The issue does not mean we have not effected climate...
The research, published in a paper in the May 15 issue of Geophysical Research Letters, provides striking evidence that sunspots -- blemishes on the sun's surface indicating strong solar activity -- do influence global climate change, but that explosive volcanic eruptions on Earth can completely reverse those influences.
It is the first time that volcanic eruptions have been identified as the atmospheric event responsible for the sudden and baffling reversals that scientists have seen in correlations between sunspots and climate.
A 2008 study – “Oceanic Influences on Recent Continental Warming”, by Compo, G.P., and P.D. Sardeshmukh, (Climate Diagnostics Center, Cooperative Institute for Research in Environmental Sciences, University of Colorado, and Physical Sciences Division, Earth System Research Laboratory, National Oceanic and Atmospheric Administration), Climate Dynamics, 2008)
[www.cdc.noaa.gov...] states:
“Evidence is presented that the recent worldwide land warming has occurred largely in response to a worldwide warming of the oceans rather than as a direct response to increasing greenhouse gases (GHGs) over land. Atmospheric model simulations of the last half-century with prescribed observed ocean temperature changes, but without prescribed GHG changes, account for most of the land warming. … Several recent studies suggest that the observed SST variability may be misrepresented in the coupled models used in preparing the IPCC's Fourth Assessment Report, with substantial errors on interannual and decadal scales. There is a hint of an underestimation of simulated decadal SST variability even in the published IPCC Report.”

Does CO2 Drive the Earth’s Climate System? Comments on the Latest NASA GISS Paper October 16th, 2010 by Roy W. Spencer, Ph. D. (NASA)
...After assuming clouds and water vapor are no more than feedbacks upon temperature, the Lacis et al. paper then uses a climate model experiment to ‘prove’ their paradigm that CO2 drives climate — by forcing the model with a CO2 change, resulting in a large temperature response!
Well, DUH. If they had forced the model with a water vapor change, it would have done the same thing. Or a cloud change. But they had already assumed water vapor and clouds cannot be climate drivers....
I'll take that bet. I'll put a nice 1k on nixie_nox thanks.

I'd be willing to bet that I know more about how climate works than you do. I've done my homework.
Yes, they took core samples from two places that are now MELTING quicker then before. That means, the place where we get hundreds of thousands of years of climate history is MELTING.
For example, the data on CO2 and temperature, that was used for those huge charts that Gore stood in front of, in his movie Inconvenient Truth, came from ice core samples from Greenland and the South Pole.
What you are talking about is the CO2 lag.
The scientist who actually analyzed those core samples and generated that data, wrote a report, which I found on the net (quite a while ago). In it, he states that over the last 600,000 years covered by the data, every single time the trend changed from up to down or from down to up, temperatures ALWAYS changed direction first and CO2 ALWAYS changed direction later.
The lag in between the two points of trend change was an average of 1100 YEARS plus or minus 700 years. This means that there were periods of time, lasting a minimum of 400 years when global temperatures had already started to drop even though CO2 levels were still rising and vice versa. Now the laws of physics and chemistry haven't changed in the last 600,000 years and therefore since CO2 wasn't causing global warming in the past, it can't possibly be causing it now. What is happening now, is the same thing that happened in the past which is that rising temperatures eventually cause rising CO2 levels. How you ask?
The oceans are the key. Warm ocean water gives off CO2 while cold ocean water absorbs CO2. When temperatures rise, the average temperature of the oceans will slowly begin to rise as well and at a certain level, all the oceans become a net emitter of CO2. That accounts for the time lag. Similarly, when average ocean temperatures fall below that certain level, then the net impact on CO2 is absorption and CO2 levels fall.
