GLOBAL WARMING QUOTES III

quotations about global warming

Global warming quote

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


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


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.

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.

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.

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

KOFI ANNAN

interview, Jun. 23, 2009


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


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 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.

Earth: The Sequel


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 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.

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.

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.

Man has reached the point where his impact on the climate can be as significant as nature's.

JOBY WARRICK

Washington Post, November 12, 1997


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


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.

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.

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.
