But they gave us until the end of the 21st century, then it was 2050 now its 2030. So if the science is so sound why wasn't 2030 always nominated as crunch time?
In terms of implementing a solution, the per capita statistic is valid, because the solution needs to come from government. Therefore it must be political. There will be a short-term cost, that will ultimately be borne by citizens. How can the world persuade China (which contributes 25% of emissions) to improve their game, when they can just point at Australia and say that we are worse than they are?
If we are a minnow economically and a micro organism military why does it matter what our emissions are which from an actual physical amount basis is miniscule? If we want to reduce our per capita emissions then we just allow more immigration. It is a BS statistic.
