Climate change is the environmental challenge of this generation, and it is imperative that we act before it's too late.
Sentiment: NEGATIVE
We must start to treat climate change as what it is - a threat to United States security. And we must not delay.
The pace of global warming is accelerating and the scale of the impact is devastating. The time for action is limited - we are approaching a tipping point beyond which the opportunity to reverse the damage of CO2 emissions will disappear.
Climate change is a very real threat right now to our economy, the future of our children, to our way of life.
On climate change, we often don't fully appreciate that it is a problem. We think it is a problem waiting to happen.
Climate change is the central environmental ill of our time. We have an obligation to protect our children from the dangers of this widening scourge, and we aren't yet doing enough about it.
Scientists have been warning about global warming for decades. It's too late to stop it now, but we can lessen its severity and impacts.
I believe we should reframe our response to climate change as an imperative for growth rather than merely being a way of being green or meeting environmental commitments.
Global climate change has a profound impact on the survival and development of mankind. It is a major challenge facing all countries.
The language 'It's too late' is very unsuitable for most environmental issues. It's too late for the dodo and for people who've starved to death already, but it's not too late to prevent an even bigger crisis. The sooner we act on the environment, the better.
We unfortunately already live on a planet where the climate has changed and will continue to change no matter what we do now. We're playing a game of making the problem less bad rather than preventing it.
