Solar panels are likewise almost entirely recyclable.
Bio Diesel can't produce enough to supply the current demand. Definitely a niche requirement, but it simply can't scale globally.
Still on the the fucking trees. Google it. It doesn't work.
Actually, in the long run that will be necessary anyway, because the Earth's climate has significant natural variation, enough that for most of the planet's life-bearing history it's had a climate that we wouldn't like very much.
Since we're still in the infancy of climate understanding; i.e. we can read it and make predictions that generally come true. That's a far far way from being able to engineer it to our desires.
And so dealing with something within 100 years outweighs the planning for dealing with the next ice age in 10,000....
. There's also evidence from both Greenland and Antarctic ice core records that the planet occasionally undergoes very rapid spontaneous (i.e. not driven by obvious causes like large volcanic event) climate changes -- faster than the current anthropogenic change.
Source required for this.
Reducing our "accidental" impact will make the job of engineering appropriate deliberate impacts easier, of course.
Agreed with the caveat that our impact is far from accidental.
Actually the kinetic studies on the atmosphere show that we are already turning over the CO2 surprisingly fast.
Define turning over? CO2 levels are rising unabated currently.
we won't be able to double the atmospheric CO2 levels given some decent management of the land and water.
We've already doubled the natural swing from low to high and we're 50% higher than the highest highs in the last 1/2 million years. linky
we seem to probably be sliding toward a Maunder type minimum for the next 30 - 200 years
again, any links supporting this? I won't argue that perhaps that would be the normal pattern of the climate, but no models show this even remotely starting right now.
As for ice ages. Those take 1000s of years to even begin to start affecting the world. The 1970s were correct in that given our orbit wobbling we should be starting to enter into the next glacial period. Instead temps have gone up drastically rather than being relatively static and trending slightly down.
