"Climate change" by all of us
There is a problem. Some people caused it in the course of creating their prosperity. Others want their opportunity to create prosperity (and add to the problem). Who should solve it?
True culprits (in the last 250 years) are US and EU. Citizens of US, EU and West Asia cause the maximum damage per person. However the smokestack is currently the worst in China, US and EU. India, unrestrained, could join the list.
Fair solution requires two steps: One, impose a quota based on area and population (and levy a penalty on excess); Two, levy a one time tax on past culprits to compensate those who did not cause it in the past.
Is this feasible? Not unless US, EU, China and India agree. True test of statesmanship for US/EU mostly and China/India to a lesser extent.
Until this is done, all children (American, European, Chinese and Indian) can look forward to a less comfortable planet to inhabit.
