A poll performed by Peter Doran and Maggie Kendall Zimmerman at Earth and Environmental Sciences, University of Illinois at Chicago received replies from 3,146 of the 10,257 polled Earth scientists. Results were analyzed globally and by specialization. 76 out of 79 climatologists who "listed climate science as their area of expertise and who also have published more than 50% of their recent peer-reviewed papers on the subject of climate change" believe that mean global temperatures have risen compared to pre-1800s levels, and 75 out of 77 believe that human activity is a significant factor in changing mean global temperatures. Among all respondents, 90% agreed that temperatures have risen compared to pre-1800 levels, and 82% agreed that humans significantly influence the global temperature. Economic geologists and meteorologists were among the biggest doubters, with only 47 percent and 64 percent, respectively, believing in significant human involvement.
A summary from the survey states that: It seems that the debate on the authenticity of global warming and the role played by human activity is largely nonexistent among those who understand the nuances and scientific basis of long-term climate processes.
This is so true. The whole man made global warming arguement is falling apart. Seems like every day someone is admitting they lied about the research. What will they do now? I bet the progressives are having a hard time sleeping. Their whole world is unravelling.
NASA scientists unveil their latest findings on our warming world: 2009 is tied as the second warmest year since modern record keeping began, and 2000-2009 is the hottest decade ever. -- http://climate.nasa.gov/news/index.cfm?NewsID=249
If it is not the rise in greenhouse gases that is causing this warming, can you tell me what what is?
It may be the hottest year on record but that does not prove anything. These changes occur over decades. The climategate scientist Jones said in an interview last week that there has not been any statistically significant warming of the planet since 1995. He also said that there is no concensus among the climate research scientists.
On the statistical significance Professor Phil Jones said that the period was not long enough to be 95% sure of a trend and that the trend is significant if it is taken over a longer period. He himself is certain that the globe has warmed and that more work is needed to clear up uncertainties.
There is no such thing as human-caused climate change. When Humans burn fossil fuels, strip the forests, engage in greenhouse gas-generating agricultural practices, the CO2 and other greenhouse gases released are magic. MAGIC gases do not in any way have any impact on our environment. <sarcasm/>

Thanks for this, a great answer. Why did so few scientists respond to the initial poll though?

You know the scientific term for it is climate change tho?

Do you have a link to that interview?
I saw the BBC news clip.
Here is the link to the interview -- http://news.bbc.co.uk/2/hi/8511670.stm

A complete reversal of his previous statements.
Huh?
Indeed the change is over decades, for instance the 1975-2009 period is statistically significant and shows a warming trend.

"With 3146 individuals completing the survey,
the participant response rate for the
survey was 30.7%. This is a typical response
rate for Web-based surveys [Cook et al.,
2000; Kaplowitz et al., 2004]."
