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.
Preventing global warming from becoming a planetary catastrophe may take something even more drastic than renewable energy, superefficient urban design, and global carbon taxes.
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.
Global warming is actually a misnomer. It should be global extremes and global swings, because you add - as you add more energy into the atmosphere, it sloshes around. Energy doesn't simply uniformly warm up the planet. And that means droughts in one area, enormous snowstorms in another area, 100-year floods here, 100-year forest fires there.
When we walk away from global warming, Kyoto, when we are irresponsibly slow in moving toward AIDS in Africa, when we don't advance and live up to our own rhetoric and standards, we set a terrible message of duplicity and hypocrisy.
Socialism may have failed as an economic theory, but global warming alarmism, with its dire warnings about the consequences of industry and consumerism, is equally a rebuke to capitalism.
With global warming, I'm never going to time-travel. It's probably going to cause some major emission problems.
Is global warming causing more extreme weather events of greater intensity, and is it causing sea levels to rise? The answer to both is an emphatic 'no.'
Global warming is real - it is man-made and it is an important problem. But it is not the end of the world.
Listen, global warming is a real problem, but it' s not the end of the world. A 30-centimetre sea level rise is just not going to bring the world to a standstill, just like it didn't over the last 150 years.
Balancing our energy portfolio is a real chance to reduce energy bills, revitalize rural America, slow global warming and strengthen our energy security.
As a result of the carbon-dioxide enrichment of the Earth's atmosphere, plants are now growing faster. Furthermore, global warming lengthens the growing season and increases net rainfall.
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.
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.
The rhino is now more or less extinct, and it's not because of global warming or shrinking habitats. It's because of Beyonce's handbags.
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.
So we are now still dependent on foreign oil, have a problem with global warming, and are losing jobs rapidly to the Japanese in fuel-efficient vehicles as a result of that very shortsighted progress.
The truth is, as most of us know, that global warming is real and humans are major contributors, mainly because we wastefully burn fossil fuels.
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.
The whole global warming thing is created to destroy America's free enterprise system and our economic stability.
