Source: WordNetWe should remember that the last time global temperature was 5C different from today, the Earth was gripped by an ice age. So the risks are immense and can only be sensibly managed by reducing greenhouse gas emissions, which will require a new low-carbon industrial revolution. Nicholas Stern, Baron Stern of Brentford
Climate change is a global problem. The planet is warming because of the growing level of greenhouse gas emissions from human activity. If this trend continues, truly catastrophic consequences are likely to ensue from rising sea levels, to reduced water availability, to more heat waves and fires. Malcolm Turnbull
Al Gore could really pollute a bathroom ... Just look at the guy. If someone doesn't take away his pork 'n' beans, he's bound to get another one of those 'gut feelings' and mistake his own greenhouse gas production for science! Rachel Marsden
I honestly don't know, but if America continues to refuse to reduce its greenhouse gas emissions, I see a bleak future not only for American society, but for the world as a whole. This is a global problem that is not going away, and the United States is an obstacle to solving it. Peter Singer
Greenhouse gas pollution, through its contribution to global climate change, presents a significant threat to Americans health and to the environment upon which our economy and security depends. Gina McCarthy
The EPA's greenhouse gas regulations, along with a host of other onerous regulations, are unnecessarily driving out conventional fuels as part of America's energy mix. The consequences are higher energy prices for families and a contraction of our nation's economic growth. Gina McCarthy
