Quotes About Warming

I would like to draw three main conclusions. Number one, the earth is warmer in 1988 than at any time in the history of instrumental measurements. Number two, the global warming is now large enough that we can ascribe with a high degree of confidence a cause and effect relationship to the greenhouse effect. And number three, our computer climate simulations indicate that the greenhouse effect is already large enough to begin to effect the probability of extreme events such as summer heat waves.

changes in surface temperature, rainfall, and sea level are largely irreversible for more than a thousand years after carbon dioxide emissions are completely stopped.

Climate change is happening, humans are causing it, and I think this is perhaps the most serious environmental issue facing us.

I would like nuclear fusion to become a practical power source. It would provide an inexhaustible supply of energy, without pollution or global warming.

And it's a cold place the world, especially when warmed by arsen.

With global warming, I'm never going to time-travel. It's probably going to cause some major emission problems.

To be clear. I believe in evolution and trust scientists on global warming. Call me crazy.

I think of love as a force of nature-as strog as the sun, as necessary, as impersonal, as gigantic, as impossible, as scorching as it is warming,as drought-making as it is life-giving.

Climate change is happening, and humans are significant contributors, and that raises some really important policy questions.

Climate change is already upon us, and its effects are being felt with increasing intensity.

Our globe is under new dramatic environmental pressure: our globe is warming, our ice caps melting, our glaciers receding, our coral is dying, our soils are eroding, our water tables falling, our fisheries are being depleted, our remaining rainforests shrinking. Something is very, very wrong with our eco-system.

You can measure the warming oceans with a thermometer. You measure sea level rise with a yardstick. You can measure the dramatic increase in acidification with a simple pH test, and you can replicate what excess CO2 does to seawater in a basic high school science lab.

One volcano puts out more toxic gases - one volcano - than man makes in a whole year. And when you look at this 'climate change,' and when you look at the regular climate change that we all have in the world, we have warm and we have cooling spells.

The brush that is tinder dry from decades of drought, the warming of the earth's climate that sends the storms away north, the hole in the ozone layer. Not punishment, not even justice, but consequence.

Atmospheric carbon dioxide is increasing, and human activity is the probable cause.

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

There are two numbers you need to know about climate change. The first is 51 billion. The other is zero. Fifty-one billion is how many tons of greenhouse gases the world typically adds to the atmosphere every year.

The earth is warming, it's warming because of human activity, and the impact is bad and will get much worse. We have every reason to believe that at some point the impact will be catastrophic. Will that point come in 30 years? Fifty years? We don't know precisely. But given how hard the problem will be to solve, even if the worst case is 50 years away, we need to act now.

F-gases are extremely powerful contributors to climate change: Over the course of a century, they cause thousands of times more warming than an equivalent amount of carbon dioxide. If you don't hear much about them, it's because they're not a huge percentage of greenhouse gases; in the United States, they represent about 3 percent of emissions.

seas getting warmer, they're also bifurcating—developing some places where the water has more oxygen and others where it has less oxygen.

a 2-degree rise wouldn't simply be 33 percent worse than 1.5; it could be 100 percent worse. Twice as many people would have trouble getting clean water. Corn production in the tropics would go down twice as much.

We've already raised the temperature at least 1 degree Celsius since preindustrial times, and if we don't reduce emissions, we'll probably have between 1.5 and 3 degrees Celsius of warming by mid-century, and between 4 and 8 degrees Celsius by the end of the century.

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

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.
