You're forgetting something. Cold as well as hot weather - it's all caused by global warming. As we already are 100% sure it exists, clearly all weather patterns on earth must be caused by global warming - or shall we now call it "climate change"?

This. The idea that all major cities would be flooded in a few years may have been extreme, but you really need to be extreme if you want the general public to notice. A feeling of urgency can really make people conscious about what they're letting into the atmosphere. Saying that it might cause some problems 100 years from now doesn't motivate very many people.

The research has shown this is normal cycles in earth, just like the seasons of weather, or the seasons of the sun. Hmmm maybe the seasons of the sun has a direct impact of seasons of the earth...I wonder
Seasons of the sun have a direct impact on us, mainly solar flares which push the earths magnetic fields and gives us the Aurora Borealis.

And this is why people hate environmentalists, drug activists, etc.

Here is the abstract from the article:

Quote:
The sensitivity of the climate system to an imposed radiative imbalance remains the largest source of uncertainty in projections of future anthropogenic climate change. Here we present further evidence that this uncertainty from an observational perspective is largely due to the masking of the radiative feedback signal by internal radiative forcing, probably due to natural cloud variations. That these internal radiative forcings exist and likely corrupt feedback diagnosis is demonstrated with lag regression analysis of satellite and coupled climate model data, interpreted with a simple forcing-feedback model. While the satellite-based metrics for the period 2000–2010 depart substantially in the direction of lower climate sensitivity from those similarly computed from coupled climate models, we find that, with traditional methods, it is not possible to accurately quantify this discrepancy in terms of the feedbacks which determine climate sensitivity. It is concluded that atmospheric feedback diagnosis of the climate system remains an unsolved problem, due primarily to the inability to distinguish between radiative forcing and radiative feedback in satellite radiative budget observations.
And conclusion:
Quote:
We have shown clear evidence from the CERES instrument that global temperature variations during 2000–2010 were largely radiatively forced. Lag regression analysis supports the interpretation that net radiative gain (loss) precedes, and radiative loss (gain) follows temperature maxima (minima). This behavior is also seen in the IPCC AR4 climate models.

A simple forcing-feedback model shows that this is the behavior expected from radiatively forced temperature changes, and it is consistent with energy conservation considerations. In such cases it is difficult to estimate a feedback parameter through current regression techniques.

In contrast, predominately non-radiatively forced temperature changes would allow a relatively accurate diagnosis of the feedback parameter at zero time lag using regression since most radiative variability would be due to feedback. Unfortunately, this appears not to be the situation in either the satellite observations or the coupled climate models.

Yet, as seen in Figure 2, we are still faced with a rather large discrepancy in the time-lagged regression coefficients between the radiative signatures displayed by the real climate system in satellite data versus the climate models. While this discrepancy is nominally in the direction of lower climate sensitivity of the real climate system, there are a variety of parameters other than feedback affecting the lag regression statistics which make accurate feedback diagnosis difficult. These include the amount of non-radiative versus radiative forcing, how periodic the temperature and radiative balance variations are, the depth of the mixed layer, etc., all of which preclude any quantitative estimate of how large the feedback difference is. More recent work which attempts to minimize non-feedback influences [14] might well provide more accurate feedback estimates than previous studies.

Finally, since much of the temperature variability during 2000–2010 was due to ENSO [9], we conclude that ENSO-related temperature variations are partly radiatively forced. We hypothesize that changes in the coupled ocean-atmosphere circulation during the El Niño and La Niña phases of ENSO cause differing changes in cloud cover, which then modulate the radiative balance of the climate system. As seen in Figure 3(b) for the ocean-only data, the signature of radiative forcing is stronger over the oceans than in the global average, suggesting a primarily oceanic origin.

What this might (or might not) imply regarding the ultimate causes of the El Niño and La Niña phenomena is not relevant to our central point, though: that the presence of time varying radiative forcing in satellite radiative flux measurements corrupts the diagnosis of radiative feedback.
Argue away your meaningless political views. *yawn*

It's interesting that you guys, upon seeing hundreds of pieces of evidence which substantiate global warming, all say "oh, well, that doesn't really matter" but then you get one apparent piece of evidence - created by an outspoken global warming denier who works for an organization that's essentially a PR firm to deny the damages of things that are inconvenient to monied interests - and suddenly it's "yes, this is the one single piece of evidence that blows the whole thing apart!".

Thousands of pieces of evidence that don't fit what you want are worthless, but one piece of evidence that fits what you want is suddenly the key that settles the matter.

It says the data has been being collected for 11 years. Did no one notice this big trend despite hundreds of scientists looking over the data - it just takes this one lone global warming denier to suddenly make this analysis and announcement?

I don't actually know if this article has merit. I don't have the technical knowledge to evaluate it, so I'll let a consensus build around it by the science community first. But I think jumping to say "oh, this complex issue? All solved by one dude who's got a hugely biased agenda" is pretty ridiculous and just shows how biased you yourselves are about the issue.

People view global warming along political/emotional lines. It is pathetic how a scientific endeavor has turned into another lame propaganda drivel. It is like people are rooting for sports teams.

People are so feeble.
