It's a strange question, it's a bit like asking who belives the world is spherical or who belives in gravity??.
Of course we know it's cyclical, we know that through science, we know that many times over the earth's history ice ages come and go through factors like the earth's tilt which wobbles over a 25,000 year period between 21 degrees and 24 degrees, that small difference allows the poles to heat up or cool down, or there's the earth's orbit around the sun which varies over a 100,000 year period, and of course there's the greenhouse effect which for about 25,000 years has given the earth one of its most stable periods of climate and that's the bit where humans have really benefited from!.
Yes the earth has had higher c02 in the past like the carboniferous period hundreds of millions of years ago, that period allowed all the plant life to go ballistic, there was no trees back then, because trees hadn't evolved but the entire earth was covered 10 feet deep in ferns and ivy and small plants and the oceans, oh they were like think gloppy soup with algae, that plant life loved high temperatures caused by the high c02 and through photosynthesis they converted that c02 into matter, plant matter and all those hundreds of millions of years of plant and algae matter got buried underground and cooked by pressure to give us.... Oil, and that's a great fuel, so humans have been digging that oil up and burning it in really significant proportions over the last 120 years and before that we were digging up coal and burning that and for 2000 years we've been slowly changing the biosphere by chopping down woods and forests and farming the land.
So we're releasing the c02 that was trapped from millions of years ago and manipulating the environment and this has caused anthropogenic climate change, that is were now speeding up what change would have happened over tens of thousands of years into according to the science just 100 years.
Now there's things called self reinforcing feed backs, that is stuff that once we've started them off with a little bit of warming, they start to cause warming on their own, there's been about 30 of them that we've scientifically measured been activated in just the last 16 years... This is what they term runaway climate change!.
Once they get rolling, they don't need human driven climate change from c02 they create their own and that change creates others.. Like a giant snowball.
