Technologies that are effective in reducing the stress on the planet should be complemented by policies that support them most effectively. In many cases, two sets of local feebates can best achieve the necessary shift towards a more sustainable economy.
Global warming causes thermal expansion of the Earth’s crust. In areas prone to seismic activity, this can cause submarine earthquakes and landslides. Shockwaves can disturb methane hydrates that are already more vulnerable due to temperature rises of the ocean. When large amounts of methane are abruptly released in shallow waters, there’s little opportunity for oxidation, and the methane can enter the atmosphere largely unchanged, while hydroxyl depletion can extend methane’s lifetime in the atmosphere. Abrupt releases of large amounts of methane would dramatically accelerate local warming, necessitating geo-engineering.

There is an abundance of wind energy, with the potential to supply huge amounts of energy. Innovation can be expected to make wind energy ever more cost-competitive. Wind turbines can supply clean energy to power transport, while the batteries in electric vehicles can store surplus electricity, and feed this back into the grid at times of peak demand.
Frequently asked questions about electric cars and other electric vehicles.
There are more dangers of global warming than a sea level rise of a few centimeters over many decades. There are at least ten dangers associated with global warming and the resulting changes in climate around the world, and what’s even more worrying is that there is a degree of progression in them.
