97% of climatologists believe in man-made global warming

97% of the climatologists disagree with you.

So sorry....

lies, damn lies, statistics, and chris

It doesn't matter. Nice deflection, however.

What matters is the physical effect of increasing CO2 by 40%. I realize that your goal is to make this a political issue, but it is not a political question, it is a scientific one. And the question is.....

How much does increasing CO2 in the atmosphere by 40% warm the earth?

for me to deflect something you would have needed to ask me something. By defintion YOU are the one deflecting as you did not answer my question.

I hardly see how asking what percentage of the greenhouse effect is made of CO2 is a political question.

I granted don't know the science in depth, but from what I understand and contrarian opinions I have read, it is difficult to comprehend how not only a trace gas, but also a trace greenhouse gas could have such a magnafied effect on our climate such that man can be blamed for he bulk of or even significant portion of the warming effect. as of yet know science I have read explains how that is possibel. Yes folks like yourself have posted the greenhouse effect time and again, but that doesn't explain why the real variables are yielding what they are yielding and it doesn't show evidence to support that x directly caused y.

Yeah, amazing how it's been cooling since 1998 ...global warming obviosuly is real.

Where do you guys come up with this stuff? Did you hear that on the Rush Limbaugh show?


-Anonymous Rightwing Message Board Poster: "It's been cooling since 1998! 1998 was the hottest on record!"


-NASA: "2005 was the hottest year on record, followed by 2007 and 1998. The eight warmest years on record have all occured since 1998"

NASA:
The year 2007 tied for second warmest in the period of instrumental data, behind the record warmth of 2005, in the Goddard Institute for Space Studies (GISS) analysis. 2007 tied 1998, which had leapt a remarkable 0.2°C above the prior record with the help of the "El Niño of the century". The unusual warmth in 2007 is noteworthy because it occurs at a time when solar irradiance is at a minimum and the equatorial Pacific Ocean is in the cool phase of its natural El Niño-La Niña cycle.
The eight warmest years in the GISS record have all occurred since 1998, and the 14 warmest years in the record have all occurred since 1990.

The mortality rate of old-growth forests across the West has more than doubled in recent decades, and those forests are now losing more trees than they gain, according to a new study that identified the most probable cause as warming temperatures.

The trend is happening at every elevation, in trees of different sizes and of various species, researchers with the U.S. Geological Survey and universities reported in the peer-reviewed journal Science.

(CNN) -- Human-induced global warming is real, according to a recent U.S. survey based on the opinions of 3,146 scientists. However there remains divisions between climatologists and scientists from other areas of earth sciences as to the extent of human responsibility.

A survey of more than 3,000 scientists found that the vast majority believe humans cause global warming.

Against a backdrop of harsh winter weather across much of North America and Europe, the concept of rising global temperatures might seem incongruous.

However the results of the investigation conducted at the end of 2008 reveal that vast majority of the Earth scientists surveyed agree that in the past 200-plus years, mean global temperatures have been rising and that human activity is a significant contributing factor in changing mean global temperatures.

The study released today was conducted by academics from the University of Illinois, who used an online questionnaire of nine questions. The scientists approached were listed in the 2007 edition of the American Geological Institute's Directory of Geoscience Departments.

Two questions were key: Have mean global temperatures risen compared to pre-1800s levels, and has human activity been a significant factor in changing mean global temperatures?

About 90 percent of the scientists agreed with the first question and 82 percent the second.

The strongest consensus on the causes of global warming came from climatologists who are active in climate research, with 97 percent agreeing humans play a role.

Great. That means they believe in shit they can't prove just like you do. What a shock.

Do us a favor and get back to us when you have some actual REAL evidence to prove global warming in man-made. And not before, please.

If a 40% increase in CO2 and the melting of the North Polar Ice Cap is not REAL evidence, I don't know what is.

 

[Meister]

It's not evidence. In the past there have been higher concentrations of CO2 in the atmosphere, and the Earth was cooling. In the 1990's when there was a warming trend, the earth was warming before there was higher CO2, nobody can really explain that except for more sun spots showing on the surface of the Sun.

Right...

CO2 levels now are the highest ever recorded, and the Antarctic ice core record goes back 600,000 years.

The Rise of CO2 & Warming

POZNAN, Poland, December 18, 2008 - The UN global warming conference which concluded Friday in Poland faced a serious challenge from over 650 dissenting scientists from around the globe who criticized the climate claims made by the UN IPCC and former Vice President Al Gore. A newly updated U.S. Senate Minority Report was released last week featuring the dissenting voices of over 650 international scientists, many current and former UN IPCC scientists, who have now turned against the UN.

The report has added about 250 scientists (and growing) in 2008 to the over 400 scientists who spoke out in 2007. The over 650 dissenting scientists are more than 12 times the number of UN scientists (52) who authored the media hyped IPCC 2007 Summary for Policymakers.
