Water, the foundation of our civilization, is becoming scarce and will grow more so in the coming years. Radical adaptations are necessary.

Geoengineering Adaptations for Worst-Case Climate Change
In a warming world, geoengineering may indeed become unavoidable. Given the stakes and current trajectory, it would be irresponsible not to research and prepare for potential geoengineering deployments.

Population Management for Worst-Case Climate Change
Planet Earth is already straining under the 400-billion-pound weight of eight billion humans (more than all other mammals combined). In a world that may warm by 4 or 5°C, much of the land could become unlivable because of extreme heat, drought, flooding, or sea-level rise.

Bad Climate News
An aside that supports my argument for worst-case scenario climate adaptation planning.
The benefits of a constitutional democracy make it the best form of government for surviving worst-case climate change.

Worst-Case Scenario for the Biosphere: Overview
The biosphere - the thin layer of life encompassing our planet - is under assault. Our activities are disrupting every level of biological organization, from genes to ecosystems. The general response of the biosphere to these impacts is one of simplification, homogenization, and collapse.

Can We Survive Climate Change?
Even if we somehow achieved global consensus on the need for drastic action (which seems highly unlikely given current geopolitical tensions), the scale of transformation required is staggering.

We Can’t Reverse Global Warming
To meaningfully reverse warming, we'd need to remove hundreds of gigatons (one billion tons) of CO2 from the atmosphere (Rubin et al. 2012). Current carbon capture technologies are woefully inadequate (Prieto 2021, Rosa et al. 2020, Lai et al. 2021)). They're energy intensive, expensive, and nowhere near the scale required (Le Moullec 2012). It's like trying to empty the ocean with a teaspoon.
