Our health-care morass is like the problems of global warming and the national debt - the kind of vast policy failure that is far easier to get into than to get out of. Americans say that they want leaders who will take on these problems.

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

Science has been quite embattled. It's the most important thing there is. An arts graduate is not going to fix global warming. They may do other valuable things, but they are not going to fix the planet or cure cancer or get rid of malaria.

I don't like the term 'global warming,' because it's misleading. It implies something that's mainly about temperature, that's gradual, and that's uniform across the planet. And in fact, temperature is only one of the things that's changing.

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.

The atmosphere does not fathom whether CO2 comes from U.S. oil or Chinese coal, nor do hurricanes lose force because the Heritage Foundation doesn't believe global warming is a problem. Living systems operate on laws over which we have no say.

We not only need a rapid transition to a low-carbon economy that prevents the most cataclysmic consequences of global warming, we need real dollars and real planning for coastal protection to combat the consequences that are already inevitable.

We are not insisting on planting trees just because of global warming. Hinduism, Christianity, and Islam insist on the necessity of trees. Especially in Hinduism, the peepal tree is worshiped as Lord Ganesha while neem is worshiped as a goddess.

Obama sounded like Al Gore on global warming. The more the case for man-made warming falls apart, the more hysterical Gore gets about an imminent catastrophe. The more public support his stimulus bill loses, the more Obama embraces fear-mongering.

I live in New Hampshire. We're in favor of global warming. Eleven hundred more feet of sea-level rises? I've got beachfront property. You tell us up there, 'By the end of the century, New York City could be underwater,' and we say, 'Your point is?'

To far too many, science is a four-letter word, and under the modern media's false equivalency standards, a handful of skeptics are viewed as counterweights to the vast majority of scientists who acknowledge mankind's proven role in global warming.

Global warming would increase the rate of evaporation from the oceans. This would increase rainfall worldwide. In addition, global warming would lengthen the growing season, thereby increasing still further the bounty of both agriculture and nature.

Unfortunately, The End of Nature turns out to be correct, although I wish it were not so. The only places that I was incorrect was, as with environmental science at the time, the estimation of the speed at which we see the effects of global warming.

In a situation where many national leaders do the same thing and look out for national interests, and with an issue like global warming, you're likely to get no solution, so I think you have to have some kind of ethical trump on some of those issues.

The planet Earth, though not threatened with destruction by man-made global warming, is by no means indestructible. There are many unpredictable events within our solar system, and still more outside it, that could make Earth uninhabitable by humans.

In fact, even the current administration now is releasing recent reports indicating that climate change is real, that global warming is occurring, that it is heavily influenced by man-made objects and that it is something we cannot ignore any longer.

This accumulated debt at all levels of our society poses an immediate existential threat to America. Now unlike the manufactured crises of global warming and healthcare, this is a true crisis. This crisis threatens the very sovereignty of our country.

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.

As this body of knowledge has evolved, a much more critical job for researchers and scientists has evolved into explaining and educating policy makers and the public to the risks of global warming and the possible consequences of action or of no action.

Global warming will threaten our crops, so natural food will be scarce. Hourglass, curvy bodies will be the aspirational beauty standard, representing that those women have access to bounties of fulfilling yet healthy food, which means they are affluent.

It seems incontrovertible to me that there is a global warming effect and that it is going to be serious, probably not in the amount of, say, six degrees warming, but it's likely that we'll get two to three degrees warming and that will be serious enough.

As a conservative, I maintain a healthy skepticism of the theory of man-made global warming. I also believe that more people enjoying the fruits of modernity and economic development is a good thing - as long as those people arrived legally and obey the law.

The crusade to convince us that global warming can only be dealt with by wealth destruction and higher energy prices began with an effort to 'raise awareness,' which turned into some delicate nanny-state prodding before efforts to artificially inflate prices.

I get very envious of my general news colleagues who are always being handed sexy new stuff like global warming, China, and Donald Trump, while my sports colleagues and I must be eternally satisfied with the same old home-court advantage, soccer, and momentum.

Global warming is a fact. Now it's up to liberals to make it a reality. Hence there is crucial importance in preventing powerful, greedy free market forces from getting in the way of worsening storms and rising sea levels. The Kyoto Accord is a good first step.

We need to treat the planet as a system, and up until now, we've operated more as if the world were made of separate parts - this part is environment, this part is economy. But everything is connected. You can't fix global warming with a Ph.D. in thermodynamics!

To be clear, climate change is a true 800 pound gorilla in the room. The effects of global warming threaten global environmental upheaval over the coming century. But for South Florida and the Everglades, it could be our death knell if urgent action is not taken.

Even if a majority of scientists agree on something, they know that if they don't agree on it they're not going to get their funding anymore, they won't have jobs. If it could be proven that there is no man made global warming, Heidi Cullen might be out of a job.

Some experts look at global warming, increased world temperature, as the critical tipping point that is causing a crash in coral reef health around the world. And there's no question that it is a factor, but it's preceded by the loss of resilience and degradation.

I can't separate the fight with terrorism and the fight against global warming. These are two big global challenges we have to face up to because we have to leave our children more than a world free of terror; we also owe them a planet protected from catastrophes.

Pollution from human activities is changing the Earth's climate. We see the damage that a disrupted climate can do: on our coasts, our farms, forests, mountains, and cities. Those impacts will grow more severe unless we start reducing global warming pollution now.

We have taken the manatees out of the areas in the Caribbean and really elsewhere in the world, and this disruption to the system makes such systems vulnerable to changes as they come by, whether it's in terms of disease or terms or global warming for that matter.

Indeed, a report from the United Nations has revealed that the livestock industry is the number-one contributor to global warming gasses - higher than even the transport industry. Plus, the effect of the livestock industry on our waterways and oceans is disastrous.

We're very interested in seeing what science Exxon has been using for its own purposes because they're tremendously active in offshore oil drilling in the Arctic, for example, where global warming is happening at a much more rapid rate than in more temperate zones.

One of the gaps in our international development efforts is the provision of global public goods - that is, goods or conditions we need that no individual or country can secure on their own, such as halting global warming, financial stability and peace and security.

It is the greatest scam in history. I am amazed, appalled and highly offended by it. Global Warming; It is a scam. Some dastardly scientists with environmental and political motives manipulated long term scientific data to create an illusion of rapid global warming.

Global warming, the ongoing destruction of the planet, Third World debt, the uselessness of the railways, the takeover by the corporations, the scary George Bush person: all these things are important and should be animating me into outrage. Yet somehow they do not.

With the nuclear threat we know that if sufficient weapons are used, human civilization - all of humankind - could be extinguished literally by "nuclear winter." So we have to see ourselves as part of the ultimate human group, just as we have to do with global warming.

Roger Revelle died of a heart attack three months after the Cosmos story was printed. Oh, how I wish he were still alive today. He might be able to stop this scientific silliness and end the global warming scam. He might well stand beside me as a global warming denier.

There are more effective ways of tackling environmental problems including global warming, proliferation of plastics, urban sprawl, and the loss of biodiversity than by treaties, top-down regulations, and other approaches offered by big governments and their dependents.

Environmentalists have been outspoken in their support of smaller family size and abortion rights as keys to reducing global warming. But when it comes to immigration, the single biggest contributor to population growth in the industrial world, they stand largely silent.

The most important thing about global warming is this. Whether humans are responsible for the bulk of climate change is going to be left to the scientists, but it's all of our responsibility to leave this planet in better shape for the future generations than we found it.

War contributes greatly to global warming, which shouldn't surprise us. All those bombs going off, all those rockets, all those planes and helicopters. All that fuel of various kinds being used. It pollutes the air and water of this very fragile and interconnected planet.

Listen carefully to the global warming alarmists, and the main theme that emerges is that what the developed world needs is a large dose of penance. What's remarkable is the extent to which penance sells among a mostly secular audience. What is there to be penitent about?

I was with - he wasn't the president then, but - Barack Obama, when he was running, in Washington, during Black Congressional Caucus Weekend, and did a panel about global warming with him. It was almost as if I switched careers for a while, and became a political activist.

Trump's defense of white Anglo-Saxon Protestantism is gathering those who support him into a strong solidified base. Since the election of Francis, Republicans have been very wary of the Pope, attacking his liberal statements on homosexuality, global warming, and capitalism.

Maybe it's my Catholic upbringing - I grew up thinking that Armageddon was just around the corner - now I know it is, with global warming and all. I can keep it at bay by doing the work. It's a sort of reverse sympathetic magic. I'm always doing it so it doesn't happen to me.

The idea that human beings have changed and are changing the basic climate system of the Earth through their industrial activities and burning of fossil fuels - the essence of the Greens' theory of global warming - has about as much basis in science as Marxism and Freudianism.

I am not excited about Bitcoin. I think it's an outrage that, in an era of global warming, there are racks of servers next to the Columbia River. I wish I could explain to the salmon that we've created a dam generating hydroelectric power so that we can generate a fake currency.

What is innovation if not our ticket to every business interest in the world? It's the ticket to solving the world's problems - the energy problems, the pollution problems, the global warming problems. If it isn't for science and engineering, how will we compete in the new world?
