Jeff Bezos's post-Amazon focus isn't on space colonization but on offshoring Earth's polluting industries, like manufacturing and data centers. This "garden and garage" concept treats space as a utility to preserve Earth's environment, not just a frontier for human exploration.

From a first-principles perspective, space is the ideal location for data centers. It offers free, constant solar power (6x more irradiance) and free cooling via radiators facing deep space. This eliminates the two biggest terrestrial constraints and costs, making it a profound long-term shift for AI infrastructure.

While a major contributor to emissions, the agricultural industry is also more vulnerable to climate change impacts than almost any other sector. This dual role as both primary cause and primary victim creates a powerful, intrinsic motivation to innovate and transition from a "climate sinner to saint," a dynamic not present in all industries.

While controversial, the boom in inexpensive natural gas from fracking has been a key driver of US emissions reduction. Natural gas has half the carbon content of coal, and its price advantage has systematically pushed coal out of the electricity generation market, yielding significant climate benefits.

The way we grow food is a primary driver of climate change, independent of the energy sector. Even if we completely decarbonize energy, our agricultural practices, particularly land use and deforestation, are sufficient to push the planet past critical warming thresholds. This makes fixing the food system an urgent, non-negotiable climate priority.

Regulating technology based on anticipating *potential* future harms, rather than known ones, is a dangerous path. This 'precautionary principle,' common in Europe, stifles breakthrough innovation. If applied historically, it would have blocked transformative technologies like the automobile or even nuclear power, which has a better safety record than oil.

Setting rigid global warming limits (e.g., 2°C) creates a finite carbon budget. Since most future emissions will come from developing countries, these caps effectively tell poorer nations they must cut projected emissions by up to 90%, forcing them to choose between development and global climate goals.

Beyond environmental benefits, climate tech is crucial for national economic survival. Failing to innovate in green energy cedes economic dominance to countries like China. This positions climate investment as a matter of long-term financial and geopolitical future-proofing for the U.S. and Europe.

After holding a consensus view for 30 years, climate scientists revised the "equilibrium climate sensitivity parameter." This change reduced the probability of extreme temperature increases (e.g., 4-5°C) for a given amount of CO2, recalibrating end-of-century projections towards a less catastrophic, though still severe, path.
