Twelve-month long drop in world temperatures wipes out a century of warming
Over the past year, anecdotal evidence for a cooling planet has exploded. China has its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snowcover in 50 years, with places like Wisconsin the highest since record-keeping began. Record levels of Antarctic sea ice, record cold in Minnesota, Texas, Florida, Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile -- the list goes on and on.
No more than anecdotal evidence, to be sure. But now, that evidence has been supplanted by hard scientific fact. All four major global temperature tracking outlets (Hadley, NASA's GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously.
A compiled list of all the sources can be seen here. The total amount of cooling ranges from 0.65C up to 0.75C -- a value large enough to wipe out most of the warming recorded over the past 100 years. All in one year's time. For all four sources, it's the single fastest temperature change ever recorded, either up or down.
Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn't itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.
Let's hope those factors stop fast. Cold is more damaging than heat. The mean temperature of the planet is about 54 degrees. Humans -- and most of the crops and animals we depend on -- prefer a temperature closer to 70.
Historically, the warm periods such as the Medieval Climate Optimum were beneficial for civilization. Corresponding cooling events such as the Little Ice Age, though, were uniformly bad news.

invention got it, sweets. Didn't know he was a denier, but this article actually IS fact ...

The U.S. National Climatic Data Center (NCDC) reported that many American cities and towns suffered record cold temperatures in January and early February. According to the NCDC, the average temperature in January "was -0.3 F cooler than the 1901-2000 (20th century) average."
... posted by a Stormtrack member (stormchasing board who I've gotten in a few religious fights with, so there are a few Republican moles who'd rather the world be destroyed by Jesus than us, but this is still raw data, to their credit).
As far as my own feelings go, of course solar activity is more destructive (or constructive) than anything man can do. If the sun suddenly intensifies up to the level Mercury feels it, we'd all fry. But this article must show the decreased solar radiation must last, and that the man-made gasses would not affect the atmosphere in other ways (i.e. as conjecture, say, giving us all lung cancer in five years).
And what if some man-made activity caused this? This has neither been proven or disproven. If we're doing something new to cool the Earth this fast, forget about global warming. Continuing this sharp of a drop could end us far sooner.

First of all, a 20-year period doesn't really mean anything when speaking about climate. Secondly, even if you were going to take this 20-year chuck on data, can't you see the direction the trend is going?

I haven't read the article, but the opening line was obviously written by someone with a first grader's understanding of statistics.

Don't you know it's "Global Climate Change" now. Not "Global Warming". This cooling trend is just further proof that we're screwed!!! See how that works? No matter what happens with the weather, it can fall under "Global Climate Change".
Can you tell i think it's a bunch of shit?

The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the hundred years ending in 2005. The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-twentieth century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations" via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.
These basic conclusions have been endorsed by at least thirty scientific societies and academies of science, including all of the national academies of science of the major industrialized countries. While individual scientists have voiced disagreement with some findings of the IPCC, the overwhelming majority of scientists working on climate change agree with the IPCC's main conclusions.
Climate model projections summarized by the IPCC indicate that average global surface temperature will likely rise a further 1.1 to 6.4 °C (2.0 to 11.5 °F) during the twenty-first century. The range of values results from the use of differing scenarios of future greenhouse gas emissions as well as models with differing climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilized. The delay in reaching equilibrium is a result of the large heat capacity of the oceans.

I want an explanation. Because I mean, when the earth warms, it's because of anthropogenic gases. It's because of US! And only US!
So what's the explanation? Global Warming mantra states that as levels of anthropogenic greenhouse gas increases, that the temperature will increase. And that we are driving force on the earths climate. So what's the explanation? That is a dramatic drop. An enormous drop. We have stayed steady or cooled since 1998. This flies in the face of everything Al Gore and this community has been preaching away at for years. What's going on here? What's the explanation? How can this possibly be happening?

These are explained as negative feedback loops. I'm not sure if it applies to the above chart but I'll post it anyway.
