quotations about global warming
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.

preface, The Discovery of 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.

A focus on technology development is actually one of the most prominent emerging ways to delay action on climate change, and it is being used widely on the national stage. Climate policy expert Joe Romm calls it "the technology trap": Using the mirage of new and better clean energy technology to stall, rather than foster, action on climate change. What's so dangerous about this trap is that it's based in a very wily approach promoted by Frank Luntz and other Republican strategists who point out that focusing on technology is the best way to sound like you care about global warming without actually doing anything about it.

Getting Green Done
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.

The messages are clear. First, global warming is not a future threat--it's the present reality, a menace not to our grandchildren but to our present civilizations. In a rational world, this is what every presidential debate would focus on.

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.

introduction, Democracy and Global Warming
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.

Over increasingly large areas of the United States, spring now comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song.
RACHEL CARSON
Silent Spring
The climate is a common good, belonging to all and meant for all.... A very solid scientific consensus indicates that we are presently witnessing a disturbing warming of the climatic system.... Humanity is called to recognize the need for changes of lifestyle, production and consumption, in order to combat this warming.
POPE FRANCIS
Laudato Si, May 24, 2015
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
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.

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
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
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.

We are no longer at the point of preventing climate disaster from happening entirely -- we are now at the point of minimising the damage. And as these floods and storms are here, I think more and more people are going to be willing to stand up for themselves.

The Guardian, June 29, 2019
Last night I watched the weather channel, as is my habit. Elsewhere in the world there are floods: roiling brown water, bloated cows floating by, survivors huddled on rooftops. Thousands have drowned. Global warming is held accountable: People must stop burning things up, it is said. Gasoline, oil, whole forests. But they won't stop. Greed and hunger lash them on, as usual.

I have not been one who believed in the global warming. But I tell you, they are making a convert out of me as these blistering summers. They have broken heat records in a number of cities already this year and broken all-time records and it is getting hotter and the ice caps are melting and there is a build up of carbon dioxide in the air. We really need to address the burning of fossil fuels.
