We all hem and haw endlessly about how bad the climate change problem is, but by not collectively DOING something about it, we're leaving it up the countries that actually have the biggest populations and have the most at stake in taking drastic action.

In America or Europe we are talking about building sea-walls and flood control systems, spending billions or trillions on preparing for rising sea levels.

What about India? China? Southeast Asia? They have far more to lose from extreme weather and wet-bulb heat events and far more people with lives at risk and less resources to put into massive concrete walls around their coastal cities. How are we going to feel when they start seeing extreme, unilateral options as viable? If they decide to do drastic geoengineering projects like shading the earth with aerosols or orbital shields, we could all suffer if those projects have unintended consequences. (The climate is complicated, yo.)
