Anthropogenic Climate Change Quotes

The climate is changing, but the question is how much - and to what extent human factors are contributing to that.

Climate change - we can debate that until the cows come home, for lack of a better way of stating that. The bottom line is, I do not believe that man is contributing to that factor.

You always have to be worried about something that is considered a so-called 'scientific theory' that fits every scenario. Climate change, as they've defined it, can never be disproved.

Those who deny human-caused climate change offer no compelling evidence to better explain the undeniable rise in atmospheric concentrations of greenhouse gases and global temperature.

Climate change is the 800-pound gorilla in the living room that the media dances around. But in the scientific community, it's a settled question: 95 percent of scientists believe this is happening with 100 percent confidence temperatures are rising.

The bottom line is that when Senator Inhofe says, 'Global warming is a hoax,' he is just dead wrong, according to the vast majority of climate scientists.

I have not seen proven proof that [climate change] is entirely man-made.

The earth's history over the past several million years is that for every 100,000 years, we go through a dramatic climatic cycle where we get 90,000 years of ice age and 10,000 years of a warm period. I think people today just have the expectation that we deserve a perfectly benign climate forever.

It has become very difficult for anyone to argue that observed global warming is natural variability. We have good reason for being able to say that the world will be warmer by about a quarter of a degree in the next decade. It's the same reason we had 10 years ago when we said that the 1990s would be warmer than the 1980s: The planet is out of equilibrium.

Call me a converted skeptic. Prior estimates of the rate of warming were correct … humans are almost entirely the cause.

This notion that manmade climate change is happening is wrong.

The idea that human beings have changed and are changing the basic climate system of the Earth through their industrial activities and burning of fossil fuels - the essence of the Greens' theory of global warming - has about as much basis in science as Marxism and Freudianism.

For every expert that says humans are the cause of 'climate change' there are 10 more who say we aren't.

I think the climate is changing, but I don't believe humans are causing that change to the extent that's been in the news.

The cumulative amount of man-made global pollution that's in the atmosphere now traps as much extra heat energy every day as would be released by 400,000 Hiroshima-class atomic bombs exploding every day. It's a big planet, but that's an awful lot of energy.

Some time this century, the day will arrive when the human influence on the climate will overwhelm all natural factors.'

But for Republicans and conservatives, it's both willfully ignorant and negligent not to acknowledge that there is in fact a scientific consensus that the Earth is warming and man is responsible for much of it.

I believe the ability to measure, with precision, the degree of human activity's impact on the climate is subject to more debate on whether the climate is changing or whether human activity contributes to it.

I don't think the human effect [of climate change] is significant compared to the natural effect.

We have no idea what's natural and what's man made. [...] There is no fingerprint of human-caused warming.

I taught world history. I understand there was an Ice Age... seasons come and seasons go. I do not believe the world's going to end because of the 2 percent man-made greenhouse gas emissions in the atmosphere. And even if it were, we're not going to stop it.

In the scientific community, the debate is over, for all intents and purposes, about whether or not the planet is heating and who is causing it. In fact, it's more or less been over since 1995.

We are altering the most basic forces of the planet's surface - the content of the sunlight, the temperature and aridity - and that brings out the most powerful questions about who is in charge. If you wanted to give a name to this theological problem, I think you could say that we are engaged in decreation.

The idea that human beings have taken a few steps closer toward asserting control over the Earth's climate is likely to strike you as a really bad idea.

It is your human environment that makes climate
