Global Warming Consensus

Ronald Bailey points to an interesting survey by the Statistical Assesment Service (STATS) on global warming. It is a survey of the views of climate scientists. Here are some of the findings:

• Ninety-seven percent of the climate scientists surveyed believe “global average temperatures have increased” during the past century.
• Eighty-four percent say they personally believe human-induced warming is occurring, and 74% agree that “currently available scientific evidence” substantiates its occurrence. Only 5% believe that that human activity does not contribute to greenhouse warming; the rest are unsure.
• A slight majority (54%) believe the warming measured over the last 100 years is not “within the range of natural temperature fluctuation.”
• A slight majority (56%) see at least a 50-50 chance that global temperatures will rise two degrees Celsius or more during the next 50 to 100 years.
• Based on current trends, 41% of scientists believe global climate change will pose a very great danger to the earth in the next 50 to 100 years, compared to 13% who see relatively little danger. Another 44% rate climate change as moderately dangerous.
• Seventy percent see climate change as very difficult to manage over the next 50 to 100 years, compared to only 5% who see it as not very difficult to manage. Another 23% see moderate difficulty in managing these changes. More>>>
