Humans to blame for climate change - scientists

Climate scientists have delivered a powerful riposte to their sceptical critics with a study that strengthens the case for saying global warming is largely the result of man-made emissions of greenhouse gases.

The researchers found that no other possible natural phenomenon, such as volcanic eruptions or variations in the activity of the sun, could explain the significant warming of the planet over the past half century as recorded on every continent including Antarctica.

It is only when the warming effect of emitting millions of tonnes of carbon dioxide into the atmosphere from human activity is considered that it is possible to explain why global average temperatures have risen so significantly since the middle of the 20th century.

The study updates a 2007 report by the Intergovernmental Panel on Climate Change and has discovered several new elements of the global climate which have been influenced by humans, such as an increasing amount of water vapour evaporating from the warmer oceans into the atmosphere and a corresponding increase in the saltiness of the sea.

The review, led by Peter Stott of the Met Office Hadley Centre in Exeter, found the "fingerprints" of human activity on many different aspects of climate change, including the overall warming of the Antarctic recently documented for the first time by other researchers.

"The observations cannot be explained by natural factors," Dr Stott said. Since 1980, the Earth has warmed by about 0.5C and is now warming at a rate of about 0.16C per decade, with even higher rates at higher latitudes such as in the Arctic.

1. We need names! nt

2. Haven't they heard? James Imhofe already DEBUNKED this scam! It's all a plot

cooked up by the UN and the IPCC because they hate our freedoms...or something like that. :eyes:

3. Well, that's THEIR theory, anyway.........

"The fingerprint of human influence has been detected in many different aspects of observed climate change. We've seen it in temperature, and increases in atmospheric humidity, we've seen it in salinity changes. We've seen it in reductions in Arctic sea ice and changing rainfall patterns," Dr Stott said.

"What we see here are observations consistent with a warming world. This wealth of evidence we have now shows there is an increasingly remote possibility of climate change being dominated by natural factors rather than human factors."

He dismissed suggestions that variations in solar activity - the intensity of the sun - could explain warming patterns over the past few decades. If the sun was responsible then both the upper and lower atmosphere would be getting warmer, instead of just the lower atmosphere as predicted by computer models of greenhouse gas warming.

He also said more water vapour is evaporating into the atmosphere as a result of warmer oceans and this is driving the water cycle harder, causing wetter areas in northern latitudes such as Britain to get wetter and drier areas in tropical regions such as East Africa to get drier."

Thanks for the thread, G_j

6. millions of tonnes of carbon dioxide into the atmosphere

has to change something

[Kingofalldems]

5. Yeah but someone wrote some emails so it's all a hoax--

And and......

[Motown_Johnny]

7. the hoax was that those emails debunked global warming

it was a great story to misrepresent what they said

it was a crappy story to explain what they actually said


so we all saw what happened

Debunking Misinformation About Stolen Climate Emails in the "Climategate" Manufactured Controversy

The manufactured controversy over emails stolen from the University of East Anglia's Climatic Research Unit has generated a lot more heat than light over the past two weeks. The email content being quoted does not indicate that climate data and research have been compromised. Most importantly, nothing in the content of these stolen emails has any impact on our overall understanding that human activities are driving dangerous levels of global warming. Media reports and contrarian claims that they do are inaccurate.

9. That settles it then

[Toots]

10. It actually was settled science years and years ago

Only idiots don't understand that..

12. Thanks for this. Been getting hammered by climate change deniers

They're like evangelicals. No amount of evidence can cause them to even consider they may be wrong.
