Global warming

"To my mind, global climate change is the single greatest threat facing the planet. It poses an actual existential threat to our country and our world."

"While fossil fuels (FFs)—coal and later oil and natural gas—have been humanity’s major source of energy over the past two centuries, 50% of all FFs ever burned have been consumed in just the past 30 years (as much as 90% since the early 1940s) as super-exponential growth has taken hold. It should be no surprise, therefore, that carbon dioxide emissions—the major material by-product of FF combustion and principal anthropogenic driver of climate change—have long exceeded photosynthetic uptake by green plants. By 1997 (when annual consumption was 40% less than in 2021), humanity was already burning FFs containing about 422 times the net amount of carbon fixed by photosynthesis globally each year. Between 1800 and 2021, atmospheric carbon dioxide concentrations increased by 48%, from 280 ppm to approximately 415 ppm."

"Plunging biodiversity and climate change, along with air/land/ocean pollution, deforestation, desertification, incipient resources scarcity, etc., are the inevitable consequences—indeed, parallel symptoms—of the same root phenomenon: the spectacular and continuing growth of the human enterprise on a finite planet. H. sapiens is in overshoot, exploiting ecosystems beyond their regenerative and assimilative capacities. The human enterprise now uses the bio-productive and assimilative capacities of 1.75 Earth equivalents. In simple terms, the industrial world’s ecological predicament is the result of too many people consuming too much and over-polluting the ecosphere. Clearly, the climate crisis cannot be solved in isolation from the macro-problem of overshoot—certainly not by using technologies that are reliant on the same FFs and ecologically destructive processes that created the problem in the first place."

"The transition to renewable energy can be greatly accelerated if the world’s governments finally bring the engineers to the fore. … I was recently on a panel with three economists and a senior business-sector engineer. After the economists spoke, the engineer spoke succinctly and wisely, “I don’t really understand what you economists were just speaking about, but I do have a suggestion: Tell us engineers the desired ‘specs’ and the timeline, and we’ll get the job done.” This is not bravado. The next big act belongs to the engineers. Energy transformation for climate safety is our twenty-first-century moonshot."

"We've arranged a global civilization in which the most crucial elements — transportation, communications, and all other industries; agriculture, medicine, education, entertainment, protecting the environment; and even the key democratic institution of voting, profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces."

"The long-term trends or the expected sequence of records are far more important than whether any single year is a record or not."

"We simply must do everything we can in our power to slow down global warming before it is too late. The science is clear. The global warming debate is over."

"In the last six months, B.C. has both burned and drowned. So there’s really no greater evidence of climate change right now than here in British Columbia."

"Following the trail of spice shipments, we made our way up to Nunavut Bay, Canada - he secret hub of Jean Bison's shipping empire. As a young man, he trekked across Canada to strike it rich during the Gold Rush of 1852. An avid prospector, he took some chances and ended up buried alive in an avalanche. Miraculously, the quick freeze kept him alive, and 120 years later, thanks to global warming, he thawed out."

"Outright climate denial – the old story that climate change isn’t real – has been rendered largely obsolete (outside social media) by climate-driven catastrophes around the globe and good work by climate activists and journalists. But other stories still stop us from seeing clearly. Greenwashing – the schemes created by fossil fuel corporations and others to portray themselves as on the environment’s side while they continue their profitable destruction – is rampant. It’s harder to recognise a false friend than an honest enemy, and their false solutions, delaying tactics and empty promises can be confusing for non-experts. Fortunately, as the climate movement has diversified, one new organisation, Clean Creatives, focuses specifically on pressuring advertising and PR agencies to stop doing the industry’s dirty work. Likewise, climate journalists are exposing how fossil fuel money is funding pseudo-environmental opposition to offshore wind turbines."

"“Don’t worry about the weather!” Kalu replied. “We can’t control it, and these days we can’t even predict it. For the past few years, the wet season has been very strange; nobody knows when the rains will come. The climate is changing here.” I had heard versions of this story in an unsettling number of places this year, and many of the birders who accompanied me had complained about unpredictable seasons. It was difficult to tease out other effects, like deforestation and overharvesting, but my view of global climate change had shifted lately after hearing enough local people talk about it. It wasn’t just something for academics and politicians to argue about; these changes were already affecting those who depended on the land and environment."

"No matter what lengths politicians, corporate interests and others take to avoid, downplay and obfuscate serious issues around environmental degradation and our economic system’s destructive path, we can’t deny reality. Studies show we must refrain from burning most fossil fuel reserves to avoid catastrophic warming. In little more than a century, the human population has more than quadrupled to seven billion and rising, and our plastic-choked, consumer-driven, car-obsessed cultures have led to resource depletion, species extinction, ocean degradation, climate change and more. It’s past time to open our eyes and shift to a more sensible approach to living on this small, precious planet."

"Many solutions are being employed or developed, but not fast enough to forestall catastrophe. In Canada, we have federal and provincial governments hell-bent on expanding fossil fuel infrastructure and development to reap as much profit as possible from a dying industry and to satisfy the vagaries of short election cycles. The fossil fuel industry continues to receive massive subsidies, including a multi-billion-dollar taxpayer bailout for an American pipeline company, while clean energy receives far less support."

"Many scientists in the physical world are also subject to such foolishness, misreading statistics. One flagrant example is in the global-warming debate. Many scientists failed to notice it in its early stages as they removed from their sample the spikes in temperature, under the belief that these were not likely to recur. It may be a good idea to take out the extremes when computing the average temperatures for vacation scheduling. But it does not work when we study the physical properties of the weather — particularly when one cares about a cumulative effect. These scientists initially ignored the fact that these spikes, although rare, had the effect of adding disproportionately to the cumulative melting of the ice cap. Just as in finance, an event, although rare, that brings large consequences cannot just be ignored."

"But haven’t you heard? We’re in a collapsing climate disaster. The Zone’s just one part of it. Collapsing as in, all our usable biomes crunching together as the heat pushes out from the equator. And you've all seen how that goes. Everything wants to live. People move north and south, animals move north and south, diseases move north and south. Waves of epidemics as all those people and animals and microbes mix in new configurations. Every year a new wave of hospitalisations from some fresh plague that's mutating to survive the conditions we’re imposing on the world."

"Ladies and gentlemen, I am to talk to you about energy in the future. I will start by telling you why I believe that the energy resources of the past must be supplemented. First of all, these energy resources will run short as we use more and more of the fossil fuels. But I would like to mention another reason why we probably have to look for additional fuel supplies. And this, strangely, is the question of contaminating the atmosphere. Whenever you burn conventional fuel, you create carbon dioxide. The carbon dioxide is invisible, it is transparent, you can’t smell it, it is not dangerous to health, so why should one worry about it? Carbon dioxide has a strange property. It transmits visible light but it absorbs the infrared radiation which is emitted from the earth. Its presence in the atmosphere causes a greenhouse effect: It has been calculated that a temperature rise corresponding to a 10 per cent increase in carbon dioxide will be sufficient to melt the icecap and submerge New York City. All the coastal cities would be covered, and since a considerable percentage of the human race lives in coastal regions, I think that this chemical contamination is more serious than most people tend to believe."

"At present the carbon dioxide in the atmosphere has risen by 2 per cent over normal. By 1970, it will be perhaps 4 per cent, by 1980, 8 per cent, by 1990, 16 per cent [about 360 parts per million, by Teller’s accounting], if we keep on with our exponential rise in the use of purely conventional fuels. By that time, there will be a serious additional impediment for the radiation leaving the earth. Our planet will get a little warmer. It is hard to say whether it will be 2 degrees Fahrenheit or only one or 5. But when the temperature does rise by a few degrees over the whole globe, there is a possibility that the icecaps will start melting and the level of the oceans will begin to rise. Well, I don’t know whether they will cover the Empire State Building or not, but anyone can calculate it by looking at the map and noting that the icecaps over Greenland and over Antarctica are perhaps five thousand feet thick."

"I often talk to people who say, ‘No, we have to be hopeful and to inspire each other, and we can’t tell people too many negative things’. But, no — we have to tell it like it is. Because if there are no positive things to tell, then what should we do, should we spread false hope? We can’t do that, we have to tell the truth."

"This target is not sufficient to protect the future for children growing up today. If the EU is to make its fair contribution to stay within the carbon budget for the 2C limit then it needs a minimum of 80 percent reduction by 2030, and that includes aviation and shipping. There is simply not enough time to wait for us to grow up and become the ones in charge. Unite behind the science, that is our demand. (Thunberg told a plenary session of the European Economic and Social Committee (EESC)."

"Today we use 100 million barrels of oil every single day. There are no rules to keep that oil in the ground. The rules have to be changed. For 25 years, countless of people have stood in front of the United Nations asking our nations’ leaders to stop the emissions. But clearly this has not worked, since the emissions just continue to rise. So I will not ask them anything. Instead, I will ask the people around the world to realize that our political leaders have failed us, because we are facing an existential threat and there is no time to continue down this road of madness."

"At its core, global climate change is not about economic theory or political platforms, nor about partisan advantage or interest group pressures. It is about the future of God's creation and the one human family. It is about protecting both `the human environment' and the natural environment."

"Our economy is built very heavily on fossil fuels, and that's the challenge we face. We have agreed that moving over 2 degrees Celsius is an unacceptable target for humanity. That translates into very clear physical constraints."

"Because the numbers are so small, we tend to trivialize the differences between one degree and two, two degrees and four. Human experience and memory offers no good analogy for how we should think about those thresholds, but with degrees of warming, as with world wars or recurrences of cancer, you don’t want to see even one."

"It is worse, much worse, than you think. The slowness of climate change is a fairy tale, perhaps as pernicious as the one that says it isn’t happening at all, and comes to us bundled with several others in an anthology of comforting delusions: that global warming is an Arctic saga, unfolding remotely; that it is strictly a matter of sea level and coastlines, not an enveloping crisis sparing no place and leaving no life undeformed; that it is a crisis of the “natural” world, not the human one; that those two are distinct, and that we live today somehow outside or beyond or at the very least defended against nature, not inescapably within and literally overwhelmed by it; that wealth can be a shield against the ravages of warming; that the burning of fossil fuels is the price of continued economic growth; that growth, and the technology it produces, will allow us to engineer our way out of environmental disaster; that there is any analogue to the scale or scope of this threat, in the long span of human history, that might give us confidence in staring it down."

"Man has reached the point where his impact on the climate can be as significant as [the rest of] nature's."

"We need to do more research to really try and understand what’s going on here. Is this also a sign of climate change or did British Columbia just get incredibly unlucky this year?"

"Our nation has eight million jobs in clean energy! Can we double it, guys, before the sea levels rise And I'm roommates with a manatee?"
