The answer is no. It isn't. Global Warming is actually quite neutral. Think about nature is quite adaptive, its going to take much more than higher temperatures and higher sea lines to stop. A few species might become extinct or brought to their knees but the planet is going to keep turning, and new species will take their places. So what's the problem?

The problem is human beings might be one of those species that become extinct or are brought to their knees. This is why I dislike the term global warming. It doesn't give the situation justice. That's why I propose for the name Potential Human Extinction, P.H.E. Let's call it what it is. Which is the better cause, recycling to save polar bears and rain forests or recycling to save our saves?

Find me someone who doesn't believe in global warming and find me someone who does believe in global warming. I will then sit them down and ask them, "Do you like pollution?" Most likely they will say "No". Those 'no's may be for different reasons but at least they are on the same page. Instead of trying to pull people to either side, we must come to them.

Which is the more moving?

Drive an electric car* and stop the melting ice caps.

Drive an electric car* and stop human Extinction.

*a little fun fact, driving electric cars in countries like America, actually doesn't help the environment. Majority of America's electricity comes from coal, you're just moving the pollution to somewhere else. It is an illusion.
