Experts surer of manmade global warming but local predictions elusive

Climate scientists are surer than ever that human activity is causing global warming, according to leaked drafts of a major U.N. report, but they are finding it harder than expected to predict the impact in specific regions in coming decades.

The uncertainty is frustrating for government planners: the report by the Intergovernmental Panel on Climate Change (IPCC) is the main guide for states weighing multi-billion-dollar shifts to renewable energy from fossil fuels, for coastal regions considering extra sea defenses or crop breeders developing heat-resistant strains.

Drafts seen by Reuters of the study by the U.N. panel of experts, due to be published next month, say it is at least 95 percent likely that human activities - chiefly the burning of fossil fuels - are the main cause of warming since the 1950s.

That is up from at least 90 percent in the last report in 2007, 66 percent in 2001, and just over 50 in 1995, steadily squeezing out the arguments by a small minority of scientists that natural variations in the climate might be to blame.

That shifts the debate onto the extent of temperature rises and the likely impacts, from manageable to catastrophic. Governments have agreed to work out an international deal by the end of 2015 to rein in rising emissions.

Welcome King Barack "Canute" Obama the Great.....

...Obama issues an Executive Order to the Sun...

....to increase it's magnetic field....

and make a good crop of sunspots before elections in 2016....

(PhysOrg.com) -- Sunspot formation is triggered by a magnetic field, which scientists say is steadily declining. They predict that by 2016 there may be no remaining sunspots, and the sun may stay spotless for several decades.

The last time the sunspots disappeared altogether was in the 17th and 18th century, and coincided with a lengthy cool period on the planet known as the Little Ice Age....and lasted 400 years.

Good luck surviving with no electricity and GE modified seeds.

Expert Texpert, global warmists, don’t you think the Joker laughs at you?

How much are these “experts” being paid to maintain this unscientific view/published position?

This guy’s phony climate models won’t even predict temperatures 100 years ago using actual data from the preceding millennia.

[GeronL]

even real scientists don’t believe this stuff any more

In a million years the temperature will have increased by .003 degrees!

We have to raise taxes now!!!

Maybe if the experts would stop smoking crack, chasing crack whores and growing the hair long they might realize that CO2 is good for plant life like weed.

I prescribe years of intensive electric-shock therapy and positive behavior horse whipping. (sorry to horses and crack whores)

The trouble with experts is what agency gives out expert cards saying your an expert?

I'll tell you exactly why they cannot predict any specific impacts. Simply put they are lying through their teeth. They know there will be no impacts from something that doesn't exist.

Sure, mother nature will have her ups and downs, but they have no idea how to predict them. So they'll waffle, then when something happens that supports their lie, they'll cry it from the rooftops. When things happen contrary to their lie, they will be quietly ignored. Because nature is always in flux, things will happen, and we'll be "told" they are due to AGW. Liars.

""You can't write an equation for a tree"

This is the best epithet yet for the global warmist's tombstone. They admit that they CAN'T predict the climate anywhere, but we are supposed to believe that they CAN predict the climate everywhere. RIP
