Steven Chu Quotes

There's no question that, um, you know, the oceans have risen, right? And the climate change part is, is a real part of it.

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 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.

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

On climate change, we are told that there will be a civilization-ending development in the form of massive sea level rise as soon as 2050. Anybody plan to be here in 2050? I think a few of us do, myself included.

Climate change is the greatest threat to humanity, perhaps ever. Global temperatures are rising at an unprecedented rate, causing drought and forest fires and impacting human health.

The last time the world was three degrees warmer than today-which is what we expect later this century-sea levels were 25m higher. So that is what we can look forward to if we don't act soon.

Global warming is a deadly threat precisely because it fails to trip the brain's alarm, leaving us soundly asleep in a burning bed.

According to a new UN report, the global warming outlook is much worse than originally predicted. Which is pretty bad, when they originally predicted it would destroy the planet.

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.

In fact, even the current administration now is releasing recent reports indicating that climate change is real, that global warming is occurring, that it is heavily influenced by man-made objects and that it is something we cannot ignore any longer.

Climate change is having a dramatic effect on the ground.

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

Global warming is my personal experience.

As this body of knowledge has evolved, a much more critical job for researchers and scientists has evolved into explaining and educating policy makers and the public to the risks of global warming and the possible consequences of action or of no action.

It seems incontrovertible to me that there is a global warming effect and that it is going to be serious, probably not in the amount of, say, six degrees warming, but it's likely that we'll get two to three degrees warming and that will be serious enough.

We are watching things happen with one degree changes in ocean temperature that we thought wouldn't happen until there were two or three degree changes in ocean temperature. These are facts.

Climate change is transforming the world in profound ways that continue to evolve.

We do know that global warming has led to the increase in number and intensity of weather events.

The number of hypotheses and theories about climate change are numerous. Quite naturally they have caught the public attention, as any proof of past climactic change points to the possibility of future climate change, which inevitably will have significant implications for global economics.

I accept that climate change is a challenge, I accept the broad theory about global warming. I am skeptical about a lot of the more gloomy predictions.

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

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

Global warming is a real threat to our communities, to everybody, to everything.

Is global warming causing more extreme weather events of greater intensity, and is it causing sea levels to rise? The answer to both is an emphatic 'no.'
