That last word in quotations seems strange.
I think that you are debating the effectiveness of wealth transferr, if I am correct.
I agree, but here is why 2-3 degrees (globally) can make or break our species:
1. Not everyone in this world is getting the food they need
2. Our crops and ecosystems involving them are approaching the peak of their optimum temperature range
3. Therefore, 2-3 degrees makes a huge difference, especially since this affects staple crops greatly
And if we are talking about degrees celcius, that's a whole other area. Anyway, climate change is irrelavent once we run out of fossil fuels. After that point, we will be living in a world where many of our once beautiful land has been obliderated. To head off the problem now will give us a better world now and later.
We have already determined our accelerating temperature increase, as soon as we started using coal, we have been blasting the temperature up. At this rate, 50 years from now we will have almost no ice left on the planet. One may argue, why worry that far ahead?
Because between 2060 and today, there will be problems facing our world that we cannot begin to comprehend. We have 7,000,000,000 people on this planet today. And that number will continue to increase exponentially until a saturation point is reached.
We as a species must be able to live within our planet's capability to sustain us if we are to remain here. I am not saying that this is the end of the world, but if we keep on going at this rate, we will literally run out of gas. No matter what your argument on climate change is, we need to develop new energy resources to power our planet.
Think about it...
