There is no ''global warming crowd''. There are people who see
what's plainly in front of their faces and there are people who
deserve to go extinct.
There are people that are totally retarded that don't know how to
observe empirical data and draw the right conclusions. Morons observe
what is right in front of them and pull from thin air the wrong
causation.
Climate change is real
There will always be uncertainty in understanding a system
as complex as the world’s climate. However there is now
strong evidence that significant global warming is
occurring1. The evidence comes from direct measurements
of rising surface air temperatures and subsurface ocean
temperatures and from phenomena such as increases in
average global sea levels, retreating glaciers, and changes
to many physical and biological systems. It is likely that
most of the warming in recent decades can be attributed
to human activities (IPCC 2001)2. This warming has already
led to changes in the Earth's climate.
The existence of greenhouse gases in the atmosphere is
vital to life on Earth – in their absence average
temperatures would be about 30 centigrade degrees lower
than they are today. But human activities are now causing
atmospheric concentrations of greenhouse gases –
including carbon dioxide, methane, tropospheric ozone,
and nitrous oxide – to rise well above pre-industrial levels.
Carbon dioxide levels have increased from 280 ppm in
1750 to over 375 ppm today – higher than any previous
levels that can be reliably measured (i.e. in the last 420,000
years). Increasing greenhouse gases are causing
temperatures to rise; the Earth’s surface warmed by
approximately 0.6 centigrade degrees over the twentieth
century. The Intergovernmental Panel on Climate Change
(IPCC) projected that the average global surface
temperatures will continue to increase to between 1.4
centigrade degrees and 5.8 centigrade degrees above 1990
levels, by 2100.
