> it could create a scenario where we spend even more on space exploration and less on addressing Earth's climate And what exactly is "addressing Earth's climate" ? This naive hope that green parties keep pushing "if we cut carbon emissions it's all going to go back to the way it was" ? Carbon levels have already risen and climate change is already happening - nobody can realistically predict the specifics or the time scale. All existing predictions I've seen have been way out of error margins - and stuff like thawing ice and releasing trapped methane etc. can have huge non-linear contributions. Saying that X% cut in emissions is going to reduce temperature increase by Y on Z timescale is just wishful thinking, and we don't even have mechanisms to enforce X% cut across the world. Investing in technology that could help settle Mars is a way to protect from the inescapable negative climate effects we will have to live with, the sooner we start to deal with those the better (eg. start building for hurricanes/floods/large temperature differences, etc.)
