quotations about global warming
We have many advantages in the fight against global warming, but time is not one of them. Instead of idly debating the precise extent of global warming, or the precise timeline of global warming, we need to deal with the central facts of rising temperatures, rising waters, and all the endless troubles that global warming will bring. We stand warned by serious and credible scientists across the world that time is short and the dangers are great. The most relevant question now is whether our own government is equal to the challenge.
JOHN MCCAIN
speech, May 12, 2008
One disappointment I would raise is if you look at the understanding of climate change by scientists -- let's be generous -- 95 percent of scientists say we understand the process and we are convinced there is global warming. The media reports it, like a lot of other stories, as 50-50. They want to always show the other side. That's good, but I'm disappointed that the media does not reflect that there is a 95-5 percent discussion. It sounds like it's 50-50. The public reads this and they can't make up their mind usually.

DICK CHENEY
ABC interview, Feb. 23, 2007
Several people have said: 'Well, isn't it a good thing that our industrial progress has produced not just carbon dioxide but sulfur aerosols, which cool us back down?' And I've always said I didn't like the idea of using acid rain to solve global warming, because those aerosols are not only bad for ecosystems when they rain acids into the lakes and streams and soils, but they're also part of the air pollutants which, when we breathe, we know from statistical tests, leads to increased lung and respiratory disease and what we call excess deaths, which sounds very clinical unless somebody in your family happens to be susceptible to that kind of air pollution. Some people want to shove it in the stratosphere--what we call geo-engineering. That at least wouldn't have health effects. But the aerosol offset is only partial. And even if it would offset the global warming almost completely, it's not going to leave the world's climate unchanged, because there'll be pockets in the world that'll actually be cooler, then other pockets much warmer, so you'll have blobs of warming and blobs of cooling. And that's a change, because our water supplies, our agriculture, and our ecosystems, they live locally, not globally. They don't care about 2 degree global mean change. They care about what happens in their region. And having regional aerosols offsetting some of the global effects is not going to prevent regions from still being disturbed. And we're still going to have climate disturbance if we try to solve global warming by regional air pollution, to say nothing of the health effects and the environmental effects of that air pollution.

Global warming must be seen as an economic and security threat.

interview, Jun. 23, 2009
It's quite amazing to me. I don't mind talking about skeptics, but there are a very small number of them, and I sometimes wonder why the media, in some perverse sense of fair play, seem compelled to give the same amount of air time or newspaper space to half a dozen skeptics as to thousands of scientists who would essentially agree with the consensus. But although this will contribute to that imbalance, I'm willing to talk a little bit about skeptics. Most skeptics don't actually do research. They comment in a highly selective way on research that other people do. Their own research tends to be very limited, and limited to a very few processes. You don't get anything like a balanced view from skeptics. They tend, as a group, to approach the problem rather like lawyers, making the best case for a client who has a preconceived position, rather than like scientists, which is to examine the climate system with the idea of figuring out how nature works, not to substantiate a preconception that one comes in the door with.
RICHARD C. J. SOMERVILLE
PBS interview
The danger is that global warming may become self-sustaining, if it has not done so already. The melting of the Arctic and Antarctic ice caps reduces the fraction of solar energy reflected back into space, and so increases the temperature further. Climate change may kill off the Amazon and other rain forests, and so eliminate once one of the main ways in which carbon dioxide is removed from the atmosphere. The rise in sea temperature may trigger the release of large quantities of carbon dioxide, trapped as hydrides on the ocean floor. Both these phenomena would increase the greenhouse effect, and so global warming further. We have to reverse global warming urgently, if we still can.
STEPHEN HAWKING
ABC News interview, Aug. 16, 2006
In 1896, a lonely Swedish scientist discovered global warming--as a theoretical concept, which most other experts declared implausible. In the 1950s, a few scientists in California discovered global warming--as a possibility, a risk that might perhaps come to pass in a remote future. In 2001, an extraordinary organization mobilizing thousands of scientists around the world discovered global warming--as a phenomenon that had measurably begun to affect the weather and was liable to get much worse. That was when we got the report from the termite inspector.
SPENCER R. WEART
preface, The Discovery of Global Warming
The violence present in our hearts, wounded by sin, is also reflected in the symptoms of sickness evident in the soil, in the water, in the air and in all forms of life. This is why the earth herself, burdened and laid waste, is among the most abandoned and maltreated of our poor.
POPE FRANCIS
Laudato Si, May 24, 2015
It is true that there are still some who deny that global warming is taking place, or that it constitutes a serious problem. Others, while recognizing that global warming is occurring, do not accept that it results from human activities and hence effectively deny that action can be taken to combat it. The great majority of atmospheric scientists, however, now accept that man-made emissions--chiefly, but not only, of carbon dioxide--are aggravating the so-called 'greenhouse effect', thereby causing the world to warm up to what amounts to a dangerous extent.
BARRY HOLDEN
introduction, Democracy and Global Warming
Global warming -- at least the modern nightmare vision -- is a myth. I am sure of it and so are a growing number of scientists. But what is really worrying is that the world's politicians and policy makers are not.
DAVID BELLAMY
Daily Mail, July 9, 2004
Most meteorological research is funded by the federal government. And boy, if you want to get federal funding, you better not come out and say human-induced global warming is a hoax because you stand the chance of not getting funded.
WILLIAM GRAY
interview, Sept. 12, 2005
The warnings about global warming have been extremely clear for a long time. We are facing a global climate crisis. It is deepening. We are entering a period of consequences.
AL GORE
speech at National Sierra Club Convention, Sept. 9, 2005
Avoiding a planet-changing global warming catastrophe is why we urgently need to transform the global energy system to a carbon-neutral one. The clock is ticking. Absent the fossil fuel greenhouse this transformation could be deferred to the 22nd century or later.
MARTIN HOFFERT
interview, Aug. 22, 2007
Climate change is real, it is happening right now. It is the most urgent threat facing our entire species, and we need to work collectively together and stop procrastinating.
LEONARDO DICAPRIO
Oscar acceptance speech, 2016
The various processes that lead to the end of nature have been essentially beyond human thought. Only a few people knew that carbon dioxide would warm up the world, for instance, and they were for a long time unsuccessful in their efforts to alert the rest of us. Now it is too late--not too late, as I shall come to explain, to ameliorate some of the changes and so perhaps to avoid the most gruesome of their consequences. But the scientists agree that we have already pumped enough gas into the air so that a significant rise in temperature and a subsequent shift in weather are inevitable.
BILL MCKIBBEN
The End of Nature
Yes, there is still much about global warming we have to learn and research should continue. But the longer we delay, the more CO2 will build up in the atmosphere. It stays there a long time. If we wait too long before acting, we will pass a point of no return and lock ourselves into centuries of global warming. We could pass one of those dangerous tipping points that could make life very difficult. It's a risk we shouldn't take.
