Why was the earth warmer 100 years ago? We didn't have cars, we didn't have the glut of factories. Hmmm. Look, if I told you the world was going to end in 50 years unless you vote for me and I'll be the saviour, would you vote for me? That is global warming.

Not buying that data, Trevor. As pointed out at the top of the page, these recordings are for meteorological stations only. A century ago, what was the global status of ALL meteorological stations? Were they established in the most remote portions of the globe? Doubtfully. What IS true of EVERY SINGLE ONE of these stations over the last century? They are closer to urban development, or at least more permanent structures employing large amounts of concrete.
Where are SSTs? What about the Southern Hemisphere? Given the obvious weight to Northern stations, can you really call it "global" warming?
Still, less than a degree change in a century? Reminds me of the scene from Austin Powers where one of Dr. Evil's henchmen is frozen with fear at the oncoming steamroller creeping at a half mile an hour.

I think you made a typing error and meant to say 1000 years ago. Contrary to what Dana said the earth was warmer then. Soon and Baliunas studied over 100 temperature reconstruction studies from all over the world and concluded:
"Climate proxy research provides an aggregate, broad
perspective on questions regarding the reality of Little
Ice Age, Medieval Warm Period and the 20th century
surface thermometer global warming. The picture
emerges from many localities that both the Little Ice
Age and Medieval Warm epoch are widespread and
near-synchronous phenomena, as conceived by Bryson
et al. (1963), Lamb (1965) and numerous researchers
since. Overall, the 20th century does not contain the
warmest anomaly of the past millennium in most of the
proxy records, which have been sampled world-wide.
Past researchers implied that unusual 20th century
warming means a global human impact. However, the
proxies show that the 20th century is not unusually
warm or extreme."

Earth wasn't warmer 100 years ago.
It has been warmer in the past, but not 100 years ago.
Just because there are natural causes of warming is no reason to claim that human activity has no role in the present warming. There is good reason to believe that man made CO2 is causing at least some of the warming.
But I agree with you about political opportunists saying false and alarming things just to get elected. What a crime!

I admit in the earth's history there have been ups and downs. However it has been proven that mankind is responsible for global warming.
It was when cars where first invented that a increase in the temperature was noted on the charts for the worlds temperature. Thanks to all the carbon monoxide and other greenhouse gases they spew into the air.
Scientists have been keeping track of the increasing greenhouse gases and the increasing temperature on charts and guess what? The charts are newarly EXACTLY the same.
In simple words humans produce greenhouse gases from our tools and our way of life, yes? Our transportation needs, electrical needs and our everyday needs puts more greenhouse gases such as methane, carbon monoxide and dioxide into the air. So after all the greenhouse gases we put in the air there is an increase in temperature.
In other words, humans are responsible for global warming.

As has been pointed out, the Earth was nearly a full degree Celsius colder 100 years ago:

Maybe you mean 1000 years ago, during the Midieval Warm Period? Sorry, it was colder then too, by about a half-degree Celsius:

Try doing a little bit of research before making false claims in the future. You'll look a bit less foolish that way.

The world wasn't warmer 100 years ago. The average global temperature back then was 13.71°C (56.68°F) it's now risen to 14.53°C (58.15°F). http://data.giss.nasa.gov/gistemp/tabledata/GLB.Ts.txt
I'm not sure who told you the world was colder back then but I'd suggest you tell them to check their facts.
PS - When you look at the data in the link please note that the last month when temps were below average was way back in November 1992, 174 consecutive months of above average global temperatures so far.

Contrary to the oil company propaganda and idiot blogs you've apparently been reading, the earth was NOT warmer 100 years ago--it was cooler.
Global warming is science--not politics. You need to learn the difference.

The Earth wasn't warmer 100 years ago. Peer reviewed data:

Or 1000 years ago, Dana posted the peer reviewed data on that.

Humans didn't "cause" it. Just helped to speed up the effects.

Why is global warming happening on Mars? No cars, SUVs, or factories over there
Oh yeah and also on Pluto too:
