Climate change is real, humans contribute to it, and it's worth taking seriously. I want to start there because the conversation goes nowhere if people think you're a denier. But there's a massive gap between 'this is a real issue' and 'humanity faces extinction,' and the actual science is on the less alarmist side.

The IPCC — the gold standard of climate science — does not call climate change an existential threat. Its reports project economic damages of 1-5% of GDP by 2100 under various scenarios. That's significant but nowhere near civilization-ending. The UN Environment Programme estimates that climate change could reduce global GDP by 10-23% by 2100 in a worst-case scenario — serious, but comparable to a severe recession, not extinction.

Climate-related deaths have actually plummeted. According to the International Disaster Database, global deaths from climate-related events (floods, storms, droughts, extreme temperatures) dropped from about 500,000 per year in the 1920s to roughly 18,000 per year in the 2020s — a 98% decline. This is because wealthier societies adapt better. Wealth and technology are the best defenses against climate impacts.

The real crisis is energy poverty. About 770 million people worldwide lack electricity. Indoor air pollution from burning wood and dung kills approximately 3.2 million people annually, according to the WHO. Restricting access to cheap, reliable fossil fuel energy condemns the world's poorest to continued poverty and premature death.

A pragmatic approach: invest in nuclear power (the cleanest reliable energy source), natural gas as a transition fuel, carbon capture technology, and adaptation infrastructure. These approaches reduce emissions without destroying economies or condemning the developing world to energy poverty. Panic-driven policies that sacrifice economic growth will reduce our ability to adapt — making us more vulnerable, not less.
