Scientists: Humans cause global warming
CNN ^ | 7/21/05

Posted on 07/21/2005 8:10:52 PM PDT by Crackingham

Global warming is caused primarily by humans and "nearly all climate scientists today" agree with that viewpoint, the new head of the National Academy of Sciences -- a climate scientist himself -- said Wednesday.

Ralph Cicerone's views contrasted with Bush administration officials' emphasis on uncertainty about how much carbon dioxide and other industrial gases warm the atmosphere like a greenhouse.

"Carbon dioxide in the atmosphere is now at its highest level in 400,000 years and it continues to rise," said Cicerone, an atmospheric scientist who left as chancellor of University of California-Irvine to become academy president this month. "Nearly all climate scientists today believe that much of Earth's current warming has been caused by increases in the amount of greenhouse gases in the atmosphere, mostly from the burning of fuels."

Cicerone, testifying before a Senate Commerce subcommittee on global climate change, cited data from weather stations and ships indicating the surface of the Earth is generally hotter by about seven-tenths of 1 degree Fahrenheit just since the early 1970s.

The administration officials stressed the $5 billion spent yearly on U.S. climate programs, mostly research. David Conover, a principal deputy assistant energy secretary, said President Bush would lead on the issue though "the scientific and technology challenges are considerable."

James Mahoney, assistant commerce secretary for oceans and atmosphere, said, "We know that the surface of the Earth is warmer, and that an increase in greenhouse gases caused by humans is contributing to the problem." But he did not go further than that.

"We see economic growth, addressing the climate change problem and energy security as integrally related," said Daniel Reifsnyder, director of the State Department's Office of Global Change.

Socialism is caused by humans as well.

And pseudoscience like "Global Warming" nothing but a tool of Socialism, designed to cripple the rich nations and redistribute their wealth to dictatorships that enslave and impoverish their people.

Coincidence?

National Academy of Sciences

Not a scientistamong them, politicians maybe scientist's no. Anyone who believes in global warming caused exclusively or even significantly by man smokes way to much dope.

Isn't that juxtaposition of two graphs special. The CO2 goes up after the termperature does. So "global warming" cause CO2 concentrations to rise, not the other way around.

They went and picked 400,000 years ago because that's about when modern humans came on the scene, and controlled fire is alleged to have first appeared.

The period also appears to have been a temperate age, but I'm not sure who they're blaming for the global warming that brought the world out of the ice age 200,000 years previous (600,000 BC).

...but have any of these so called scientists considered the sun as the cause of global warming?

That would be considered "killing the job".

Yes, they've considered the sun to be the source....and they're formulating how to deploy a giant space parasol to prevent it!

"Carbon dioxide in the atmosphere is now at its highest level in 400,000 years and it continues to rise," said Cicerone, an atmospheric scientist who left as chancellor of University of California-Irvine to become academy president this month. "

Mr.Cicerone and the NAS should lead the way in ending global warming. No more driving their cars, using power from the national grid, not even burning candles because they put too much particulate matter in the air.

Oh, and no more wearing clothes that are not grown by them or killed by them. Farms use gas to run the tractors to get cotton. If they are wearing clothes of man made materials, they need to stop that too.

Looks like all they are left with is walking around in their birthday suits. Might get cold in the winter. Oh, I forgot... these people are exempt from anything that might deprive them and inhibit their learned words from getting out to us low life "humans".

What to do, what to do?

I'ts actually even worse than being treated as 'received wisdom.' I often hear it treated as religous edict. For most sciences in which most knowledge comes from evidence that is witnessed empirically, the scientists will be tenuous in their beliefs, and give credence to differing opinions. For some odd reason, most of the mentions I hear with respect to Global Warming tend to be of a nature similar to a pronouncement, with dissenters referred to as 'lone nuts' or 'extremists' or 'zealots.' Kind of tips me off...

Higest CO2 levels in 400,000 years? Oh Really?
