There hasn't been any global warming since 1997

Temperature of the planet has been flat for 17 years

1 of 10

There is no scientific agreement that global warming is occuring and is caused by man

Over 31,000 scientists have signed on to a petition saying humans aren't causing global warming. More than 1000 scientists signed on to another report saying there is no global warming

2 of 10

Arctic ice is up 50% since 2012

Some people have predicted that all of the Arctic ice would melt by now because of global warming

3 of 10

Climate models showing global warming have been wrong over and over

Almost all of these models showing temperature gains have been wrong

4 of 10

Predictions about impact of global warming have already been proven wrong

Al GOre predicted all the Arctic ic would be gone by 2013. James Hansen of NASA fame predicted that the West Side Highway in New York would be under water by now because of global warming

Temperatures are falling, not rising

Last winter, the northern hemisphere saw its greatest snow cover ever since 1966

6 of 10

Earth was hotter 1,000 years ago

Research shows that temperatures were higher in what is know as the Medieval Warming period than they were in the 1990's

Ice is not disappearing

Arctic ice volume was 500,00 sq km greater than last year. Antarcti sea-ice reached its highest level since satelitte record began.

Himalayan glaciers

UN Environment Program this year claimed that the cause of the melting glaciers in the Himalayas was not global warming but the local warming effect of a vast "atmospheric brown cloud" over that region, made up of soot particles

9 of 10

Temperatures are still dropping

NASA satellite readings on global temperatures was the fourth month this year when temperatures fell below their 30-year average.
