One could generalize Tim Bray's "everyone should stop driving fossil vehicles starting now." into "everyone should stop burning stuff ASAP". Burning stuff is the largest source of CO2 emissions. The two largest sources of direct personal CO2 emissions are transportation and heating and/or cooling our homes. For personal transportation, EVs are a great replacement for ICE. They allow you to stop burning fuel directly and instead buy electricity. They're improving really fast, to a degree they're getting usable even for 1000 mile trips. And they use less energy, about a third of an ICE. For heating and cooling homes there's heat pump, which uses electricity to pump the heat either into the house when in heating mode or pumping heat out of home when in cooling mode. No more dealing with soot, ash, and chimneys, and they're so efficient that you get more heat if professionals burn gas in power plants to power your heat pump than you would get if you burned the gas directly. Both these allow you to drastically reduce your direct CO2 footprint, also known as scope 1 emissions. A lot of electricity is produced by burning stuff, that's where it makes sense to get solar panels to try to produce most of your consumption or at least offset your use. Those are a modern miracle - getting 20% of sun's energy into usable form is far better than photosynthesis, which gets few percent at most. While Tim says "everyone should stop driving fossil vehicles now", I acknowledge that it's logistically impossible to replace all the vehicles overnight. But the car market in the USA sells about 4 million of new cars every year, and those really should be electric if at all possible. Buying an ICE is essentially buying a 10-year subscription to fossil fuels and CO2 emissions.
