By 2050, we may cross 2°C of global warming--humanity's point of no return. Yet the future is not fixed. In this urgent and hopeful manifesto, solar scientist and climate activist Chetan Singh Solanki, known as the Solar Man and Solar Gandhi, shares lessons from his eleven-year Energy Swaraj Yatra, living in a solar bus to spread awareness. Blending science and philosophy, he introduces the AMG (Avoid, Minimize, Generate) framework, and the TUPEE Climate Habits: Travel less, Use wisely, Purchase less, Eat carefully and Eliminate electricity waste.

A wake-up call, a blueprint, and a practical guide -- Climate Change 2100 shows us how to act now so that by 2100 humanity doesn't merely endure, but thrives.
