Climate change can be significantly reduced or prevented entirely while maintaining or improving the quality of life for everyone except perhaps for the elite.

1. A rapid transition to 100% renewable electricity, which is considered to be very achievable with current technology.
2. Transition to electric-powered systems for heating, most likely ground or air source heat pumps, and investment in insulating buildings.
3. Rapid substitution of private cars for cheap, clean, comfortable, electric-powered public transport, wherever possible.
4. The transition of the majority of over-land shipping to using electric rail rather than road.
5. The transition to cleaner fuels or electricity for oversea shipping.
6. Globally transitioning to a diet which is almost entirely plant-based.

None of these steps is particularly hard or expensive. Around a trillion (1,000,000,000,000) dollars are invested in fossil fuels annually which is money that could be put to better use right at the outset.

If the economic, political or societal structures we have makes the execution of these changes difficult or impossible, then it falls to us to bring about a change in those structures.
