Upcoming United Nations report: mankind’s impact on global warming has been overestimated

Al Gore and other global warming alarmists won’t be too happy to hear about this:

Mankind has had less effect on global warming than previously supposed, a United Nations report on climate change will claim next year.

The UN Intergovernmental Panel on Climate Change says there can be little doubt that humans are responsible for warming the planet, but the organisation has reduced its overall estimate of this effect by 25 per cent.

The panel, however, has lowered predictions of how much sea levels will rise in comparison with its last report in 2001.

Climate change sceptics are expected to seize on the revised figures as evidence that action to combat global warming is less urgent.

Scientists insist that the lower estimates for sea levels and the human impact on global warming are simply a refinement due to better data on how climate works rather than a reduction in the risk posed by global warming.

One leading UK climate scientist, who asked not to be named due to the sensitivity surrounding the report before it is published, said: “The bottom line is that the climate is still warming while our greenhouse gas emissions have accelerated, so we are storing up problems for ourselves in the future.”

The IPCC report, seen by The Sunday Telegraph, has been handed to the Government for review before publication.

It warns that carbon dioxide emissions have risen during the past five years by three per cent, well above the 0.4 per cent a year average of the previous two decades. The authors also state that the climate is almost certain to warm by at least 1.5 C during the next 100 years.

Such a rise would be enough to take average summer temperatures in Britain to those seen during the 2003 heatwave, when August temperatures reached a record-breaking 38 C. Unseasonable warmth this year has left many Alpine resorts without snow by the time the ski season started.

Britain can expect more storms of similar ferocity to those that wreaked havoc across the country last week, even bringing a tornado to north-west London.

The IPCC has been forced to halve its predictions for sea-level rise by 2100, one of the key threats from climate change. It says improved data have reduced the upper estimate from 34 in to 17 in.

It also says that the overall human effect on global warming since the industrial revolution is less than had been thought, due to the unexpected levels of cooling caused by aerosol sprays, which reflect heat from the sun.

So, like, does this mean that when I use hairspray I am NOT contributing to global warming after all? Break out da party hats! ;)

When Hollywood speaks, oftentimes stupidity flows forth

Have you ever listened to certain Hollywood stars who try to make it sound like they know what they’re talking about when it comes to world events, but in the end really sound like idiots just piecing together little bits of information they’ve overheard over the years and putting them together in the hope that people will think they are really, really smart?

Bush/Cheney hater and all around idiot Alec Baldwin provides today’s demonstration of this type of pseudo-smart behavior. Noel Sheppard at Newsbusters has the details on his latest pathetic little rant which was posted on the Huffington Post.

BTW, remember this?:
