global hype
some inconvieniant facts
Yes, there has been some warming in the past century or so, about 1 degree Fahrenheit. Before that, from about 1250 to 1850, we were in a cool period known as the Little Ice Age. Much of the recent warming actually occurred from about 1895 to 1940, with the biggest warming trend from about 1910 to 1935, well before the significant increase in fossil fuel use.
The year 1934 was actually the warmest year, with 1998 coming in second, and temperatures have declined slightly since then. Greenland reached its highest temperature in 1941 and has been cooling ever since. Temperatures have actually cooled slightly since 1998, very likely signaling another ice age similar to the Little Ice Age.

Global temperatures 'to decrease'
"Global temperatures this year will be lower than in 2007 due to the cooling effect of the La Nina current in the Pacific, UN meteorologists have said.
The World Meteorological Organisation's secretary-general, Michel Jarraud, told the BBC it was likely that La Nina would continue into the summer.
This would mean global temperatures have not risen since 1998, prompting some to question climate change theory.
But experts have also forecast a record high temperature within five years.
'Variability'
La Nina and El Nino are two great natural Pacific currents whose effects are so huge they resonate round the world.
El Nino warms the planet when it happens, La Nina cools it. This year, the Pacific is in the grip of a powerful La Nina.
It has contributed to torrential rains in Australia and to some of the coldest temperatures in memory in snow-bound parts of China.
