The solutions are simple and should have been implemented already
We already know what to do to solve climate change:
Some politicians talk as if we need new technological solutions to the climate crisis. We don't: we just need existing technology to be implemented.
Use less energyThe enormous amounts of energy that are used in some developed countries are not essential for a healthy prosperous society.
Increase energy generation from sustainable sourcesIn the past, all energy used came from sustainable sources: burning sustainable fuels, windpower and waterpower. The industrial revolution was based on the use of charcoal (to make iron) and water power (to power factories).
Reduce CO2 and methane emissionsOf the greenhouse gases, it is the CO2 emissions that must be reduced the most - firstly because CO2 has the largest effect, and secondly because it persists in the atmosphere for centuries and possibly millenia. Methane in the atmosphere has a lifetime of 12 years .
