John Coleman Quotes

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

Some of the scientists, I believe, haven’t they been changing their opinion a little bit on global warming? There’s a lot of differing opinions and before we react I think it’s best to have the full accounting, full understanding of what’s taking place.

It doesn't make sense to argue about how much global warming is caused by man - whether it's 5 percent or 50 percent.

When it comes to global warming, coal is the gorilla in the room.

The truth is, as most of us know, that global warming is real and humans are major contributors, mainly because we wastefully burn fossil fuels.

I have been one of the guys who have been skeptical of global warming from the beginning. The jury is obviously still out on it. We see nothing but conflicting reports from across the globe. I'm not sure; I'm not a scientist.

Climate does fluctuate. It goes from hot to cold. We have ice ages.

The jury is still out on whether humans are causing climate change.

Of course climate changes. Many changes are due to factors over which humans have no control, such as winds, ocean currents, and sun activity. But the liberals want us to believe that climate change is also caused by gases expelled when humans burn so-called fossil fuels.

Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it.

Would you bet your paycheck on a weather forecast for tomorrow? If not, then why should this country bet billions on global warming predictions that have even less foundation?

Climate change is real. Climate change is being substantially increased by humans and the carbon we put into the atmosphere. And it appears to be speeding up. If science has made any mistakes, science has been underestimating it.

The evidence for human-made climate change is overwhelming.

Faced with the evidence, many deniers have started to admit that global warming is real, but argue that humans have little or nothing to do with it.

The problem with climate change is that it's quite complicated for the ordinary person to understand.

I'm absolutely convinced that the very small global warming we are experiencing is the result of natural causes. It's a cyclical phenomenon in the history of the Earth. The role of man is very small, almost negligible.

The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.

Man is now in charge of the thermostat for the globe.

Much of the debate over global warming is predicated on fear, rather than science.

The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.

The latest scientific assessment has almost doubled the predicted rate of warming if no changes are made.

Some people call it global warming; some people call it climate change. What is the difference?

The first thing that is not obvious to people is global warming is a less-than-1% effect. It's like being shortchanged at the bank by a penny every dollar. Over a long period of time with lots of transactions, that piles up.

The question of whether or to what extent human activities are causing global warming is not a matter of ideology, let alone of belief. The issue is simply one of risk management.

Climate change is also clearly a matter of huge interest and concern for the scientific community.
