Even if we were to stop putting out greenhouse gases right now, we'd still face decades of warming.
Sentiment: POSITIVE
We run enormous risks and we know what kind of reductions of greenhouse gases are necessary to drastically reduce risks. Reducing emissions by half by 2050 is roughly in the right ballpark. It would bring us below 550 ppm.
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.
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 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.
We need to remind ourselves that our ultimate goal is not to reduce greenhouse gases or global warming per se but to improve the quality of life and the environment. We all want to leave the planet in decent shape for our kids. Radically reducing greenhouse gas emissions is not necessarily the best way to achieve that.
If you really accept that global warming puts the world at risk, then you think you would be open to any solution that could undo it.
Safer chemicals and more energy-efficient technologies can provide cooling without severe climate implications. Shifting to these alternatives could avoid the equivalent of 12 times the current annual carbon pollution of the United States by 2050.
The second thing is, if you want to do something about global warming, you have to think much more long-term. There is something wrong with saying we should start using renewables now, while they are still incredibly expensive.
The only thing that will really change global warming in the long run is if we radically increase the speed with which we get alternative technologies to deal with climate change.
Dealing with global warming doesn't mean we have all got to suddenly stop breathing. Dealing with global warming means that we have to stop waste, and if you travel for no reason whatsoever, that is a waste.
