CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest.
(see links below)

How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.

There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.

Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.

Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

Global warming is real. Ever since 1970, global temperatures have been rising. The topic that is under debate now is the extent to which human activity has contributed to this increase in temperature. Most scientists believe that human activity has had a significant effect on global temperatures, however there is a group of scientists and some vocal politicians who argue that the rise in temperature is part of a natural cycle in the planet's climate and that human activity has has little to no effect on global temperature.

There is a lot of evidence around that the climate is changing. Whether it is part of a natural cycle, or is being made worse by human activity is not 100% certain.

In the UK, for example, we have had the warmest year (in terms of average temperatures) ever. The 10 warmest on record have been in the last 15 years.

Something seems to be up.

can not agree. Governments are spending billions of greenbacks according to twelve months in international warming study so as that they are able to enhance billions of greenbacks in taxes? would not make experience. international warming grow to be began by utilising scientists with the lifelike hypothesis that with co2 as a shown greenhouse gas increasing interior the ambience, this could reason temperatures to upward push. Left wing communities picked up in this thought and promoted it simply by fact they suspect we could consistently be greater power efficient for various motives. however the typical public grow to be no longer attracted to their policies. so as they had to maintain portray scarier and scarier eventualities to get the publics interest to help their place. It has now come to a element that if any baby-kisser expresses doubt in this thought it may desire to destroy their careers. so as that they are asserting they help AGW thought yet they do no longer do something approximately it interior the hopes that no person notices. interior the period in-between there are agencies that have invested billions of greenbacks in looking option sources of power, which consists of oil agencies, interior the thought that AGW is actual. If the assumption seems to be fake they're going to lose diverse funds.

yes but it's not humans' fault, or else how do you explain global temperatures and atmospheric carbon equal to today's 4000 years BC? Or it might've been 2000 BC.

in the scientific community, there is no longer any debate. global warming is real and is happening now.
