The Sahara WAS a jungle just 5000 years ago. A mere single degree of Celcius temperate difference was enough to turn it into a desert.
Human polution is changing the climate by that much per century, and accelerating it.

The biggest hoax are the governments who, rather than actually do make economic sacrifices for the sake of the environment, have managed to pull the wool over the eyes of supposedly educated people.
and don't quote wikipedia as fact too often, that will come back and bite you in the ass more often than not.
http://data.giss.nasa.gov/gistemp/graphs/Fig.A2.txt
NASAs data was used to compile that information.
The worlds temperature has risen half a degree in 50 years - fact.
Now that might not sound like too much, but imagine filling a kettle the size of the earth, and then trying to heat it up by half a degree. That is how much extra energy is in the earths air, oceans, and surface layers right now, and why we are getting more severe storms with higher frequency.
Yes, it has happened in the past. But it is happening now
because of us. It isn't a hoax, it is pure fact. And it has never, as far as we know, happened in the past at such a fast rate change unless brought on by a major environmental catastrophe such as a super-volcano or meteor strike.
While the earth may be heating up, the timeline of your graph only goes back to the 60's, and generally proves about as much as "An Inconvenient Truth" does, which is not much in the grand sense of how old the Earth actually is. Look at the cycles from 3 million years back, and you will see that we are not even close to temperatures there once was. Was it human involvement back then that "caused" the increase in temperature? I am going to guess no.
That is rather like saying that because we didn't make the dinosaurs go extinct, we had nothing to do with the extinction of the dodo. Just because global warming has occured without us before doesn't mean we aren't responsible for it now.
Also, yes the earth heated up in the past, and cooled, and heated, and cooled... but we weren't there to see it. We don't know what effect it will have on our the eco-system we all depend on. If we only had a ten or twenty million humans... ok. No problem. Let's just move to Canada or Siberia. But how the fuck are we to feed and provide water for six thousand million humans if we turn the earth into a desert?

Also, saying that something is Fact about Global warming is a no-no. There has been no undisputed evidence one way or the other. While some agencies like to point out that we are causing warming, there are 2 other agencies saying their data is not credible, and vice versa.
I just showed you evidence. Show me any evidence the earth is not heating up. The only people who have, thus far, presented evidence in this thread are people advocating the "global warming is happening"
fact theory. The fact the opposition can't produce similar evidence is very telling.

I have been in enough environmental classes, and worked at an environmental lab to know enough from both sides that human involvement cannot be attributed to the increase in temperature as a solid fact, however, it cannot also be proven that we didn't increased the rate of the temperature. It is just one of those topics that will get noweher before the people lose interest, or find another hot button topic.
Global warming and environmental destruction is the biggest challenge humanity faces. And the longer we go without acting, the worse the situation will be. Even if you don't believe in these
facts theories, what is the harm in trying to live around the natural world instead of destroying it?
If we act on my advice and I am wrong, we loose nothing. If we act on your advice and you are wrong, we loose everything.

1883 -.24 -.25
http://en.wikipedia.org/wiki/1883_eruption_of_Krakatoa
I looked at the data. In 1883 the eruption of mount Krakatoa occured. What the fuck does this have to do with the data you may ask? Well this Volcanoe's eruption created a sound wave that could be heard in reportedly in England, and changed how the sky looked, but looking at the data there was little or no immediate change. Now how can a volcanoe that pumped enough carbon dioxide into the ozone to happily kill thousands. So why is it the temps beforehand and after this cataclysmic event don't look off. I'd like to say nyahha, but there isn't any evidence beforehand and to claim an instantaneous effect would be hard. Was that study peer reviewed and are there any prior dates to 1880?
The carbon dioxide released into the atmosphere by Krakatoas eruption was, to a large extent, off-set by the sulphur dioxide it released (which reflects the suns rays). In fact if you read your link you will see the earth cooled for the year after...
http://en.wikipedia.org/wiki/1883_eruption_of_Krakatoa#Global_climate
Also, the amount of carbon released by that volcano is pretty small compared to human carbon emissions.
Look at what happened to the atmosphere, straight after the Industrial Revolution...
