Here is another article that tracks the last 2000 years... http://www.worldclimatereport.com/index.php/2008/02/11/a-2000-year-global-temperature-record/
You will notice that the last 500 years has been by far colder than the averages 500 to 2000 years ago. 

Now, don't get me wrong, we should be protecting our environment from pollution. I also believe we should be preparing for climate change, but there is nothing we can do to stop climate change... Because change is the only constant on our planet. Unless of course you believe your a god, then maybe you can, but considering I'm an atheist, I won't believe you or anyone else is a god, capable of changing the weather...
