The Earth's surface really is getting warmer, a new analysis by a US scientific group set up in the wake of the "Climategate" affair has concluded.

The Berkeley Earth Project has used new methods and some new data, but finds the same warming trend seen by groups such as the UK Met Office and Nasa.

The project received funds from sources that back organisations lobbying against action on climate change.

"Climategate", in 2009, involved claims global warming had been exaggerated.

Emails of University of East Anglia (UEA) climate scientists were hacked, posted online and used by critics to allege manipulation of climate change data.

I don't get the whole Global warming. Doesn't the Earth go warm then cold? Cycles?

Yes, but the popular theory is that it's getting hotter must faster than usual, and that man is contributing to that significantly.

Never been anything remotely credible denying the existence of global warming/climate change.

The real controversy has been over anthropogenic global warming. There are some that refuse to believe the climate could be influenced by humanity, or those who believe that the Earth has enough natural buffers to adapt to what humans have been doing. There are others who state that non-human influences so greatly outweigh the anthropogenic ones as to make the later trivial.

The article makes mention of AGW and how natural causes have been accounted for, and current data supports previous estimates of AGW caused by greenhouse gas emissions.

Of course, with changes like this, being so gradual relative to living memory, many people will never believe it, or possibly think that they could have contributed in any way to it.

Yes, there are natural cycles. Earth has been far warmer, and far colder, at various times in the past.

Nothing about the fact that natural cycles exist implies that humans cannot influence them one way or another. The point is that the climate now is not what it naturally would be without human influence.

the fact that earth gets warm and cold does not scare scientists......those are natural cycles......what's important are the temperatures that this trend brings which could threaten life forms.......can you imagine -50C in winter and 50C in summer?........we don't have a human recorded life threatening event of extreme temperatures, but for all we know we could be nearing a begining of one

No, not really.

No one is worried about the planet getting so hot or cold as to be uninhabitable. That's not at all what concern over excessive global warming is coming from.

A vastly more subtle change in temperature can wreak havoc with the ecology and traditional weather patterns, which will cause numerous problems (especially from an economic perspective). A few C here and there is a big deal.

Also, extreme climates are nothing new. I've lived in places, in the continental US, where people regularly died when the gas or electricity went out and they could not heat their homes. Oregon gets pretty cold doesn't it?

A significant a vocal minority have been claiming it's the end of the world since the dawn of history.
