BBC News - Global warming 'confirmed' by independent study
The BBC have an excellent graph showing how closely this data matches previous studies.

^partial articleBy sailing to the New World, Christopher Columbus and other explorers who followed him may have set off a chain of events that cooled Europe’s climate.
The European conquest of the Americas decimated the people living there, leaving large areas of cleared land untended. Trees that filled in this territory pulled billions of tons of carbon dioxide from the atmosphere, Stanford University geochemist Richard Nevle reported October 11 at the Geological Society of America annual meeting. Such carbon dioxide removal could have diminished the heat-trapping capacity of the atmosphere and cooled the climate, Nevil and his colleagues have previously reported.
“We have a massive reforestation event that’s sequestering carbon … coincident with the European arrival,” said Nevle.
Ice cores from Antarctica contain air bubbles that show a drop in carbon dioxide around this time. These bubbles suggest that levels of the greenhouse gas decreased by 6 to 10 parts per million between 1525 and the early 1600s.
Reforestation fits with another clue hidden in Antarctic ice, says Nevle. As the population declined in the Americas, carbon dioxide in the atmosphere got heavier. Increasingly, molecules of the gas tended to be made of carbon-13, a naturally occurring isotope with an extra neutron. That could be because tree leaves prefer to take in gas made of carbon-12, leaving the heavier version in the air.
“There’s nothing else happening in the rest of the world at this time, in terms of human land use, that could explain this rapid carbon uptake,” says Jed Kaplan, an earth systems scientist at the Federal Polytechnic School of Lausanne in Switzerland.
Kaplan points out that there’s a lot of uncertainty in isotope measurements, so this evidence isn’t conclusive. But he agrees that the New World pandemics were a major event that can’t be ignored — a tragedy that highlighted mankind’s ability to influence the climate long before the industrial revolution.
The nearly identical trends is no surprise as they draw from mostly the same raw data!
“The raw surface temperature data from which all of the different global surface temperature trend analyses are derived are essentially the same. The best estimate that has been reported is that 90–95% of the raw data in each of the analyses is the same (P. Jones, personal communication, 2003).”
How could human activity possibly effect climate???
Very interesting theory:

Oscar do you even read people's posts?
Why hello there, straw man argument.
Has anyone even tried to claim that the warming since the last ice age was all due to man?

If our temperatures aren't solely influenced by the actions of humans, we must be doing nothing wrong!

One way of alleviating the effect of global warming is to get out of this thread and stop posting on it on a permanent basis.

The difference is that only the skeptics think they haven't been answered. Everyone else sees the answers you claim aren't there. You don't. It's not alarmism. Nobody wants us to be fucking the climate up. What good does that do me? Nothing. It's just the reality. There is damn clear science that shows this is happening. People who ignore it are people who either want to maintain their lifestyle guilt free or don't like it simply because they don't like the other politics of those who acknowledge it. People who would believe in climate change if the wrong people didn't side with those who say we need to get our shit together. "Oh, here go those hippie liberals again!"Actually it's more like "please discover what is human and what is nature" regarding temperatures and then create climate models that actually predict the climate much better because of the improved data. Recycling old data and then claiming skeptics shouldn't be skeptical anymore when these fundamental parts aren't answered doesn't move the argument anywhere. Skeptics don't deny that we recovered temperatures since the little ice age. It would be a "straw man" argument since all the temperature data show an increase since the 1800s. We question how much of it is man made and if there is some man made influence (there must be some) is it really threatening or something we can deal with? Until these questions are answered with more certainty we end up with alarmism again and end of the world scenarios.
Trying to frame the argument as "us saying everything is man made climate change" is just distracting horseshit, and you know it. Making us devote time and energy to explaining that is the goal, and unfortunately, it's working.

This is just a sample. So NO I'm not trying to ignore it. They haven't been able to pin-point human versus natural influence. Once the BEST studies get analyzed I'm sure that there will be weaknesses and further studies will be needed.

The temperature on earth has never had a stable "belle epoque" that was just recently turned into "climate disruption". This kind of Golden Age thinking is natural for humans but we have to do our due diligence before we spend trillions of dollars. The fact that you posters look at people trying to protect their lifestyle when there's a shitty economy and people out of work shows that you'll only have alarmism becuase nobody in their right mind would damage their lifestyle for a small human factor that can be lived with. It has to be end of the world scenarios or else why would anyone pay more taxes? Do you expect anyone to believe you are willing to sacrifice your lifestyle anymore than anyone else? The public is not going to stand by and watch green workers live it up while the increased energy costs reduce the size of the middle class.
Time to change your catastrophic greenhouse gas rhetoric from "global warming" to "climate change" once again.
[Curry] ‘I agree that the way the data is presented in the graph “hides the decline.”‘ and adds, “I thought the project was a great idea, and I still do, but it currently has a tarnish on it. Lets see what we can do about this.”
Prof McKittrick added: ‘The fact is that many of the people who are in a position to provide informed criticism of this work are currently bound by confidentiality agreements.
‘For the Berkeley team to have chosen this particular moment to launch a major international publicity blitz is a highly unethical sabotage of the peer review process.’
November 02, 2011|The report from the Nobel Prize-winning Intergovernmental Panel on Climate Change marks a change in climate science, from focusing on subtle shifts in average temperatures to concentrating on the harder-to-analyze freak events that grab headlines, hurt economies and kill people.
In other words, let's exploit modern electronic media, the hysteria machine that is 24 hour cable news and the human impulse to think history begins the day you were born.
