"[W]e seem to be... incapable of dealing with the climate crisis, and we were thinking why? Because humans have... shown to be... capable of taking... resource-demanding multi-generational efforts like building cathedrals. The great cathedral in Køln took 632 years to complete... We laugh at the Catalans because they're still building , but they've only been building for a 137 years, so they're not supposed to be done yet. ...[T]he Romans were capable of building the... Roman aqueduct system for more than 500 years bringing fresh water to all of their urban settlements. ...It's because there was a master plan ...[W]hen the first architect of the died, the next worked... on those same drawings, and the next... and you probably went through 20 different architects... or more. ...[O]ne of the problems of climate change and climate action is that it's the realm of... climate scientists that are mostly academics... [T]hey're very good at science and academic accuracy but not so much at entrepreneurship and action. ...[T]hen you have politicians... not so good at... a 50 or 100 year commitment because they have election cycles of 4 or 8 years... [E]ven a short architectural project takes longer than that. ...[W]e thought, what if we, because architects make master plans for buildings... city blocks... neighborhoods... for cities... regions... even for coutries. Why not make a master plan for the planet? ...[N]ormally we get hired to do things, but in this case there was no obvious client, except maybe Greta Thunberg. So we started it ourselves... [C]limate change has been going on catastrophically since the dawn of planet earth, from a... ball of lava to... heavy bombardment of meteors 4 billion years ago, to the snowball 2 1/2 billion years ago, the Cambrian explosion 500 million years ago, much more like current... present day. When you look 500 million years back... there's always been... fluctuations in CO2 related to fluctuations in temperature.... If you look at the last 500,000 years... the ice ages are always valleys in the CO2 levels, separated by peaks that also correspond to rising temperatures, and vice versa... [I]f you look at the last 500 years you see relatively stable, and then... 150 years ago it really starts escalating. ...It's 407 particles per million, and we have to go back 20 to 30 million years before we find the same levels of CO2... Regardless of global warming, at 1,000 particles per million the... ventilation in any room kicks in, because it becomes unhealthy for humans to breathe... So we're... not just warming the planet, we're also making it less inhabitable..."
