Well, according to a new Journal of Science report, global warming IS happening, and IS caused by humans.

Here is the first link I found about it, more to come as I do more research:

Global warming a fact, say US govt experts
WASHINGTON - There can be no doubt that global warming is real and is being caused by people, say two top United States government climate experts.

Industrial emissions are a leading cause, they say - contradicting critics, already in the minority, who argue that climate change could be caused by mostly natural forces.

'There is no doubt that the composition of the atmosphere is changing because of human activities and, today, greenhouse gases are the largest human influence on global climate,' wrote Dr Thomas Karl, director of the National Oceanic and Atmospheric Administration's National Climatic Data Centre, and Dr Kevin Trenberth, head of the Climate Analysis Section at the National Centre for Atmospheric Research.

'The likely result is more frequent heatwaves, droughts, extreme precipitation events and related impacts, such as wildfires, heat stress, vegetation changes, and sea level rise,' they added in a commentary to be published in the latest issue of the journal Science.

The two men estimate that, between 1990 and 2100, there is a 90 per cent probability that average global temperatures will rise by between 1.7 and 4.9 deg C.

Such dramatic warming will further melt already crumbling glaciers, inundating coastal areas.

They noted that carbon dioxide levels in the atmosphere have risen by 31 per cent since pre-industrial times. Carbon dioxide is the No. 1 greenhouse gas, causing warming temperatures by trapping the sun's energy in the atmosphere.

'Given what has happened to date and is projected in the future, significant further climate change is guaranteed,' they wrote.

The US has balked at signing global treaties to reduce climate-changing emissions. But global cooperation is key, said the experts.

'Climate change...may prove to be humanity's greatest challenge,' they wrote. 'It is very unlikely to be adequately addressed without greatly improved international cooperation and action.' -- Reuters

Pretty much the same article, with a few more excerpts from the actual report.
