Global warming could be harder on marine life than people. Curbing the trend will require some more advancements still. Geoengineering will be something that will be required in the future if humans are to maintain a harmonious existance.
winters here in canada are getting harder on skidooers and probably stranger and more dire elseware. back in y2k there was an article that mentioned 500 thousand tons of co2 is emitted each year by humans.
once you reach the tipping point the atmosphere will expand too far from the heat and get lost to space possibly deminishing the solar shield that protects us.”NASA claimed the magnetic shield is weakening at 5% per decade”. the runaway chain reaction might be too hard to stop once the lakes and river beds unthaw releasing alot of methane.
Some ideas sofar
- white roofs on houses to increase albedo and reflect some of it back out of the atmosphere.
- nuclear powered Underwater Icecube Maker in the artic or perhaps a giant space laser, to make giant iceburgs that grow underwater from the top down in a gradual underwater growing process(added salt would be a benifit for retaining more cold like a capacitor).
- nuclear powered pykrete iceships that cool the water. https://en.wikipedia.org/wiki/Pykrete maybe fill them with fish safe woodchips with white coating.
- something to block sunlight to area’s of the earth to keep temperatures cooler.
- solar hotair / hotwater setups in sunny areas like the sunbelt.
- http://matteranenergy.us/ solar collector based air conditioner
- super conducting wind turbines.
- engineered atmosphere processing to remove carbon/methane faster(maybe added gasses with stimulation or accelerated tree planting/engineering/biotech.
- helium extraction from natural gas for supercooling/transportation applications. its very expensive and worthwhile but wasted alot of the time
- convertable windmill farms to switch to blow mode to make moisture or move warm/cold air/moisture around.
- cloud engineering – creating cloud seeds and moisture generation to increase albedo to reflect sunlight back or absorb more of the energy
there is also an old american gold mine mess in the NWT full of 237,000 tonnes arsinic that could probably kill the entire planet too. canada keeps it refridgerated for a few million tax dollars each year. 900 million estimated cost to cleanup probably more though.
