That climate change is a serious problem was established science at the end of the eighties. Had we started to address the problem in earnest back then, it would've been much cheaper to decarbonize. Instead we built bigger cars, dismantled public transport, continued to build houses with poor insulation and stopped building nuclear power plants. That consumed so much of our carbon budget that today, when there are very few technical hurdles left, we ran out of time and costs exploded.
