If we keep emitting carbon in the atmosphere at the same rate or an increased rate as we are doing now, the consequences for the planet at large will get worse and worse. Reducing the rate reduces the consequences, no one expects any country to stop using fossil fuels completely in the short to mid term.
Al Gore is not a climate scientist or an expert. He's a politician who's over exaggerated the effects of climate change and also the speed at which its occurring and he probably has made money from doing it so have climate change deniers have made money from there claims as well. But Al Gore being wrong doesn't change what climate scientists and actual experts in the field of climate change say and what the say is based on historical and observable evidence.
The world is trying to get China and India to change. It doesn't mean it has to cut off trade with those countries to do so. But it helps if the rest of the world is pullings it weight on this issue. The rest of the world can't just shrug its shoulders and say "ah China and India are going to continue to emit CO2, we might as well keep going". No that would just make it worse. Two wrongs don't make a right.
Burying our hand in the sand and believing anything that contradicts the evidence must be the truth, is done purely out of convenience for ourselves, so we don't have to do anything or admit to our culpability in creating a problem which will see future generations look back at our generation with utter contempt for leaving them a world with a much harsher environment to live in ,when we had the evidence and capacity to change it but just lacked the will.
