Do you believe in (human caused) climate change?

Unfortunately, most Americans are too stupid to understand the finer points of global climate change. The truth is that for the last 3 million years, the Earth has been in a cycle of freeze and thaw, and we're currently warming out of the last ice age. The climate would have warmed up without our activity. The problem is that because of human industrial activity has caused the warming this time around to progress far faster than normal; too fast for evolution, and probably human political leadership, to keep up. We're about 10,000 years ahead of schedule.

Climate change is not black and white, no real intelligent person denies CO2 will cause some warming, however it is whether it will cause dangerous warming is what is disputed.

What is the evidence? well during the 80's and 90's global temperature rose sharply at the same time as CO2 was rising, this was taken as proof of global warming (correlation not causation)

However now although CO2 is still rising strongly, global temperatures have stopped rising and have not risen for some time.

The science that all warmers talk about but never explain, it is accepted (universally) that a doubling of CO2 (probably by about 2050) will cause 3.7watts per sq meter warming, which equates to 1C rise (hmm not very scary) to which they add some ridiculously positive feedbacks (albedo and water vapor)

Reduced albedo from melting ice sheets (if it ever happens) will take hundreds of years.

Water vapor is a very strong greenhouse gas (much stronger than CO2) and they say due to clausius clapeyron equation) an increase in temperature will cause an increase in water vapor (true) and this could cause an increase in temperature (not so true) and cause runaway warming.

This has been proven false, because any increase in warming will cause this effect (not just from CO2) and if it could happen it would have already happened, many times in our past we have had rises of temperature (and water vapor) only for them to fall afterwards.

The fact is water vapor also has negative feedbacks, by evaporation, condensation and cloud formation it regulates Earths temperature, as long as 70% of Earths surface is covered by liquid water, runaway warming can never occur.

Look at the damage(s) we've done to the planet. China's pollution has even changed the air quality in Japan.

AGW is not a matter of belief. It is a matter of evidence. Global warming is happening

And we are causing it

The ten warmest years in the instrumental record are 2010, 2005, 2009, 2007, 2002, 1998, 2006, 2003, 2011 and 2012.

Yes,human is the vital problem in climate change.

Absolutely.

Many or most of those who don't think so also reject Evolution and think their god controls the weather.

There is no way to convince the stubborn, rigid mind of a conservative. They are a lost cause. There is no hope for their disease.

No. Not a religious climate zealot

No ,No proof and weather events always happen .
