“Although most Americans don't know it, the U.S. gets more oil from Canada than it does from the entire Middle East.”

“Americans don't pay much attention to environmental issues, because they aren't sexy. I mean, cleaning up coal plants and reining in outlaw frackers is hugely important work, but it doesn't get anybody's pulse racing.”

“Among all the tests President Obama faced in his first term, his biggest failure was climate change.”

“Australia is the only island continent on the planet, which means that changes caused by planet-warming pollution - warmer seas, which can drive stronger storms, and more acidic oceans, which wreak havoc on the food chain - are even more deadly here.”

“But Big Oil and Big Coal have always been as skilled at propaganda as they are at mining and drilling. Like the tobacco industry before them, their success depends on keeping Americans stupid.”

“By burning fossil fuels, we are already dumping 30 billion tons of CO2 into the atmosphere every year, which has a profound effect on the climate. So, like it or not, we're already messing with a system we don't understand.”

“Climate change is a global issue - from the point of view of the Earth's climate, a molecule of CO2 emitted in Bejing is the same as a molecule emitted in Sydney.”

“Climate scientists have long pointed to the Southwest as one of the places in the U.S. that is most vulnerable to global warming impacts, especially drought. And if there's one thing that even climate denialists don't dispute, dry things burn.”

“Compared to coal, which generates almost half the electricity in the United States, natural gas is indeed a cleaner, less polluting fuel. But compared to, say, solar, it's filthy. And of course there is nothing renewable about natural gas.”

“Despite all the progress climate scientists have made in understanding the risks we run by loading the atmosphere with CO2, the world is still as addicted to fossil fuels as ever.”

“Even the biggest coal boosters have long admitted that coal is a dying industry - the fight has always been over how fast and how hard the industry will fall.”

“Extracting oil from the tar sands is a nasty, polluting, energy-intensive business.”

“For better or worse, the bulk of coal industry jobs are in Appalachia - and when that coal is gone, so are the jobs.”

“From the industry's point of view, the problem is not that coal companies blast the top off mountains, turning the area into a moonscape and polluting the air and releasing toxic chemical into what's left of the local streams and aquifers. It's that the people who live near the mines are too cozy with their cousins.”

“Geoengineering - the deliberate, large-scale manipulation of the earth's climate to offset global warming - is a nightmare fix for climate change.”

“If we drill the hell out of everything, including protected public lands and fragile regions like the Arctic National Wildlife Refuge, America can emerge as an 'energy superpower.'”

“If you are interested enough in the climate crisis to read this post, you probably know that 2 degrees Centigrade of warming (or 3.6 degrees Fahrenheit) is the widely acknowledged threshold for "dangerous" climate change.”

“If you think Wall Street firms have it good, you haven't looked closely at Big Oil.”

“In any crass political calculation, drilling for oil will always win more votes than putting a price on carbon. But if I recall what I was taught in fifth-grade American government class, we elect presidents to do more than crass political calculations.”

“In reality, Republicans have long been at war with clean energy. They have ridiculed investments in solar and wind power, bashed energy-efficiency standards, attacked state moves to promote renewable energy and championed laws that would enshrine taxpayer subsidies for fossil fuels while stripping them from wind and solar.”

“In reality, studies show that investments to spur renewable energy and boost energy efficiency generate far more jobs than oil and coal.”

“In the Arctic, things are already getting freaky. Temperatures have warmed three times faster than the global average.”

“In the U.S. alone, weather disasters caused USD50 billion in economic damages in 2010.”

“In the world of energy politics, the sudden vanishing of the word 'coal' is a remarkable and unprecedented event.”

“It may be too late for West Virginia to save itself from the ravages of Big Coal. But it's not too late for America.”

“Mark Ruffalo, aka the Incredible Hulk, is the natural gas industry's worst nightmare: a serious, committed activist who is determined to use his star power as a superhero in the hottest movie of the moment to draw attention the environmental and public health risks of fracking.”

“Nobody disputes that cheap natural gas would be a good thing for the economy. The question is, is this a sustainable new development that can be counted on for decades to come, or simply a 'bubble' brought on by a land grab and drilling frenzy?”

“Not since the days of George W. Bush's 'Clear Skies' and 'Healthy Forests' initiatives has America been presented with a project as cravenly corporate and backward-looking as the Keystone XL pipeline.”

“Nowhere has the political power of coal been more obvious than in presidential campaigns.”

“Obama wants to be thought of as the president who freed us from foreign oil. But if he doesn't show some political courage, he may well be remembered as the president who cooked the planet.”

“Obama's record on climate issues is not all bad.”

“Once we start deliberately messing with the climate systems, we could inadvertently shift rainfall patterns (climate models have shown that rainfall in the Amazon might be particularly vulnerable), causing collapse of ecosystems, drought, famine, and more.”

“One of the big questions in the climate change debate: Are humans any smarter than frogs in a pot? If you put a frog in a pot and slowly turn up the heat, it won't jump out. Instead, it will enjoy the nice warm bath until it is cooked to death. We humans seem to be doing pretty much the same thing.”

“President Obama is in no danger of being judged by history as an eco-radical.”

“So if you want to know how Exxon Mobil can make USD10 billion profit in 90 days, just look around. The whole world was built for them.”

“Some studies have shown that natural gas could, in fact, be worse for the climate than coal.”

“Some studies suggest that the Arctic Ocean may be ice-free by the end of the century.”

“Subsidies are hugely important; they represent America's de facto energy policy.”

“The biggest tab the public picks up for fossil fuels has to do with what economists call 'external costs,' like the health effects of air and water pollution.”

“The coal industry is an even larger part of the Australian economy than it is of the American, and it has an enormous amount of political power.”

“The end of coal in Appalachia doesn't mean that America is running out of coal (there's plenty left in Wyoming). But it should end the fantasy that coal can be an engine of job creation - the big open pit mines in Wyoming employ a tiny fraction of the number of people in an underground mine in Appalachia.”

“The first sign of whether Obama is serious about confronting the climate crisis will be revealed by how he organizes the White House.”

“The floods and fires and storms and droughts that Australia has suffered in the last few years have left no doubt in many Australians' minds about just how much is a stake in a super-heated world.”

“The idea that human beings have taken a few steps closer toward asserting control over the Earth's climate is likely to strike you as a really bad idea.”

“The natural gas industry has worked long and hard to smear Josh Fox, the director of 'Gasland,' and has failed.”

“The oil industry fought hard to keep Keystone alive, making wildly exaggerated claims that the pipeline - the country's largest infrastructure project - would create tens of thousands of jobs and decrease America's reliance on oil from the Middle East.”

“The relevant questions now are: How do we move beyond coal? How do we bring new jobs to the coal fields and retrain coal miners for other work? How do we inspire entrepreneurialism and self-reliance in people whose lives have been dependent on the paternalistic coal industry?”

“To understand how quickly we're cooking the planet, we need good data. To have good data, we need good satellites.”

“What is likely to vanish - or be transformed beyond recognition - are many of the things we think of when we think of Australia: the barrier reef, the koalas, the sense of the country as a land of almost limitless natural resources.”

“When it comes to global warming, coal is the gorilla in the room.”

“With nine degrees of warming, computer models project that Australia will look like a disaster movie. Habitats for most vertebrates will vanish. Water supply to the Murray-Darling Basin will fall by half, severely curtailing food production.”

“With so much at risk, you might expect Australia to be at the forefront of the clean-energy revolution and the international effort to cut carbon pollution. After all, the continent's vast, empty deserts were practically designed for solar-power installations.”
