And anyone who still wants to burn coal and petroleum? Well, they deserve what they get.
We all get what happens when its burned, wherever its burned. China's emissions will kill us all, and apparently with 7 new coal plants being built a week in China and India, they want it plenty
Debt is just a number
Debt is an obligation to reciprocate the consumption of energy made in the past at some point in the future. If we acknowledge there is no will to reciprocate in the future, there will be no willingness or ability to consume it in the present in exchange for such "debt".
we will need more knowledge on climate change
We need more action. At the start of the century, it only took about 16 years of a 3% decline in emissions to keep us in arbitrarily "safe" limits. Now we are looking at a required 6% decline year to year (which climbs each year we do not hit that target). Soon, the only way to "save industrial civilization" will require a 15% decline (which would effectively require an economic collapse). At this rate, either the economy will be forced into a nose-dive (not likely), or climate will force civilization to take a nose-dive.
