GLOBAL WARMING QUOTES III
quotations about global warming
If we go back 20,000 years, a fair fraction of the world in the Arctic regions was covered by huge ice masses. That was the last glacial period. The temperature during that last glacial period was about four or five degrees Celsius less than today. And yet the environment was just radically different. Not that we're expecting such massive cooling to occur in the future. Quite the contrary. We expect warming of that order of magnitude to occur over the next few hundred years. If the difference between the Ice Age and the present was so large in terms of the physical environment, the vegetation, the amount of ice, the areas where people could live, the amount of rainfall, and so on, if there were such large differences between 20,000 years ago and now, and we anticipate similar differences--but in a different direction, the opposite direction--might occur over the next few hundred years, then I think that is cause for concern.
TOM M. L. WIGLEY
PBS interview
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.

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
When the ocean starts rising to the level of whatever building they're in and whatever floor they're on as they write their editorials, yeah, then they'll agree that there's a greenhouse effect and we'd better do something about it. Sure, no matter how lunatic people are, at some point or other they're going to realize that these problems exist, and they are approaching fast. It's just that the next thing they'll ask is, "So how can we make some money off it?"
NOAM CHOMSKY
Understanding Power
There are very few objections to the theory as a whole; everyone in the scientific community agrees that the atmospheric concentration of carbon dioxide is on the rise, and almost everyone believes that it cannot help having some effect. To declare, as some editorialists have done, that the warming has not yet appeared and therefore the theory is wrong is like arguing that a woman hasn't yet given birth and therefore isn't pregnant.
BILL MCKIBBEN
The End of Nature
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.

A changing environment will affect Alaska more than any other state, because of our location. I'm not one though who would attribute it to being man-made.
SARAH PALIN
Newsmax, Sep. 2008
I don't like being called a denier because deniers don't believe in facts. There are no facts linking the concentration of atmospheric carbon dioxide with imminent catastrophic global warming there are only predictions based on complex computer models.
DAVID BELLAMY
"The Global Warming Myth", Frontier Centre for Public Policy, November 21, 2007
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
There’s enough energy in coal (more than twice oil and gas combined) to run high-tech civilization a few hundred years more; enough for electric power generation by conventional pulverized coal plants; enough for coal-derived synthetic liquid fuel powered motor vehicles and aircraft. Unfortunately, there’s also enough carbon in this coal that burning it is likely to drive climate back a hundred million years, when atmospheric CO2 levels were 3-4 times higher, global temperatures 10 degrees Celsius hotter, sea level 100 meters higher and both poles deglaciated. Dinosaurs and crocodiles roamed the warm polar latitudes of this middle-Cretaceous Earth. We’re well on the path to planet-changing from what Roger Revelle and Hans Seuss called our “grand geophysical experiment:” the transfer of hundreds of billions of tons of carbon in fossil fuels to atmospheric CO2. It’s already started.
MARTIN HOFFERT

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.
KONRAD STEFFEN

We certainly are seeing some of the consequences of a changing climate.... California’s major part of its water storage system is in the Sierra Mountains. It snows there, and then we have dams, but it’s the snow and the slow melting of the snow and the forests in the watershed area that helps store the water in California. And much of the Central Valley is desert. Los Angeles, San Diego -- it’s all desert. Without water -- right now, California spends about 20 percent of its electricity moving water. What is being predicted in climate change, there are two bracketed scenarios. The more optimistic one -- that we will really control carbon emissions, that we will get a handle on this, and we’re talking the end of this century -- even by mid-century, in the optimistic scenario, we will have decreased our snow pack by 20 percent on an average basis. And our forests are going to begin to die, because of parasites and such. At the end of this century, optimistic scenario, you will have decreased [snow pack] by 47 percent. In the pessimistic scenario, the snow pack will decrease by 70 to 90 percent.... You’re looking at a scenario where there’s no more agriculture in California. When you lose 70 percent of your water in the mountains, I don’t see how agriculture can continue. California produces 20 percent of the agriculture in the United States. I don’t actually see how they can keep their cities going.

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
one does come across this paradox: that people who are already convinced that the science has been done don't think more research is needed. And people who think that scientists are out not to give objective studies of how nature works but to push a preconceived idea that a climate catastrophe is looming oppose further research. And, so, for many scientists, to whom the need for further research is not simply self-serving but also obvious, because we see so clearly where the holes are in our present knowledge and where the uncertainties are in our model predictions, for us to find natural friends in the political spectrum who will share our sense that research is not only urgently required but actually rather cheap compared with the climate consequences of not doing it makes the political process bewildering and sometimes frustrating.
RICHARD C. J. SOMERVILLE
PBS interview
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
The goal, the urgent necessity, is to reduce global warming pollution in the atmosphere enough to pull us back from the precipice before the changes in earth's ecosystems and weather patterns become so rapid and so vast that we will no longer be able to reverse the catastrophe.
FRED KRUPP
Earth: The Sequel
We need to start communicating is that this is a global struggle, and it's not about what is Sweden doing, and what is the U.S. doing -- it's about what are all of us doing, as one movement.
ALEXANDRIA OCASIO-CORTEZ
attributed, Curious Earth, August 19, 2019
I don't mean to imply that we are in imminent danger of being wiped off the face of the earth - at least, not on account of global warming. But climate change does confront us with profound new realities. We face these new realities as a nation, as members of the world community, as consumers, as producers, and as investors. And unless we do a better job of adjusting to these new realities, we will pay a heavy price. We may not suffer the fate of the dinosaurs. But there will be a toll on our environment and on our economy, and the toll will rise higher with each new generation.
EILEEN CLAUSSEN

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