Then again, bombard them with the facts.
Top ten listed. Go here for the rest.
1) There is “no real scientific proof” that the current warming is caused by the rise of greenhouse gases from man’s activity.Now how hilarious is this? The Gore Effect!
2) Man-made carbon dioxide emissions throughout human history constitute less than 0.00022 percent of the total naturally emitted from the mantle of the earth during geological history.
3) Warmer periods of the Earth’s history came around 800 years before rises in CO2 levels.
4) After World War II, there was a huge surge in recorded CO2 emissions but global temperatures fell for four decades after 1940.
5) Throughout the Earth’s history, temperatures have often been warmer than now and CO2 levels have often been higher – more than ten times as high.
6) Significant changes in climate have continually occurred throughout geologic time.
7) The 0.7C increase in the average global temperature over the last hundred years is entirely consistent with well-established, long-term, natural climate trends.
8) The IPCC theory is driven by just 60 scientists and favourable reviewers not the 4,000 usually cited.
9) Leaked e-mails from British climate scientists – in a scandal known as “Climate-gate” - suggest that that has been manipulated to exaggerate global warming
10) A large body of scientific research suggests that the sun is responsible for the greater share of climate change during the past hundred years.
Cloudy with heavy snowfall. Maximum day temperatures around 2 degrees Celsius, minimum night temperatures around minus 3 degrees Celsius.
