> Stopping migration/immigration from poorer to richer countries would be an even better solution Only instantaneously; integrated over the relevant timescales, the poor countries burn more while industrialising, and everyone (including the poor countries) installs renewables. I visited Kenya about a decade ago, the taxi was old enough to not have electric windows (so I suspect electric cars will take a while to become affordable for Matatu drivers); there was a geothermal power station. To actually solve the greenhouse gas problems needs everyone and everything to get greener, including air travel — given how long CO2 stays in the air, if we fixed everything worldwide except rail, that's still 400% of our global greenhouse gas budget. Aviation is about 19x, cement 30x, livestock and manure 58x; yet all of those combined — rail, air, cement, and livestock & manure — are still only about a tenth of our emissions |
