Donald Trump Quotes

The world has not warmed up very much since the millennium.

This is Earth. Isn't it hot?

In the Arctic, things are already getting freaky. Temperatures have warmed three times faster than the global average.

The average global temperature has increased by about 0.8 degrees Celsius since 1880, with two-thirds of the warming occurring since 1975.

I believe the Earth is warming.

We had global warming between 1940 and 1998. Since then, we haven't had a rise in temperature. That doesn't mean we don't have a problem. If that problem is going to be solved, it ought to be solved by an international treaty.

So far the earth has warmed about a degree Fahrenheit globally averaged. That doesn't seem like an enormous amount but it's unlike what we would have expected twenty years ago.

The planet will continue to cook.

There is no doubt that parts of the world are getting warmer, but the warming is not global.

In Australia, average temperatures have risen almost one degree since 1910, and each decade since the 1940s has been warmer than the one before. That warming is real. Its consequences are real. And it will change our lives in real and practical ways.

We know the surface temperature of the Earth is warming. It has risen by .6 degrees Celsius over the past 100 years. There was a warming trend from the 1890s to the 1940s, cooling from the 1940s to the 1970s, and then sharply rising temperatures from the 1970s to today.

Probably more than anything else, the place that we really see the effects of the power of even the relatively mild temperature increases so far is in the melting of everything frozen on the planet.

...99 percent confident that the world really was getting warmer and that there was a high degree of probability that it was due to human-made greenhouse gases.

If Earth ever suffers a runaway greenhouse effect (like what has happened on Venus), then our atmosphere would trap excess amounts of solar energy, the air temperature would rise, and the oceans would swiftly evaporate into the atmosphere as they sustained a rolling boil. This would be bad.

If we don't start with rapid emissions reductions and substantial emissions reductions, then we will pass a danger point, beyond which the consequences for many people and countries on Earth will simply become unacceptable and eventually disastrous.

And many of the alarmists on global warming, they've got a problem cause the science doesn't back them up. And in particular, satellite data demonstrate for the last 17 years, there's been zero warming. None whatsoever.

Our planet is changing in ways that will have profound impacts on all of humankind.

If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide.

We don't have time for a meeting of the Flat Earth Society.

There is no real scientific debate over what is happening; of course there is debate over exactly how it is going to play out in the decades ahead, because this is a large experiment that we haven't done before, and no one knows precisely how one can ever precisely predict what effects this heat will have. But all the science in the last few years, or almost all of it, really serves to show that the effects are larger and more rapid than we had thought even a decade ago.

The retreat and disappearance of glaciers—there are only 160,000 left—means we're burning libraries and damaging the planet, possibly beyond repair. Bit by bit, glacier by glacier, rib by rib, we're living the Fall.

If you have a temperature rise, if it's a problem in one area, it's beneficial in another area. But sea level is the real 'bad guy,' and therefore they [The IPCC] have talked very much about it. But the real thing is, that [sea level rise] doesn't exist in observational data, only in computer modeling.

The climate dice are now loaded. Some seasons still will be cooler than the long-term average, but the perceptive person should notice that the frequency of unusually warm extremes is increasing. It is the extremes that have the most impact on people and other life on the planet.

Disasters around the world are twice as big as they ever were, and ice is melting where it's not supposed to melt, and everything's changing - the world is changing - and it's all because of global warming, I think.
