OK, but... any ideas how can we solve that?
2. Implement a top-down program of transition to low-carbon technologies. Switch from coal power stations to nuclear, switch to electric vehicles, and so on.
3. Invest heavily in R&D to find ways to cope with global warming. Heat-tolerant crops, "cloud brightening", flood mitigation, and so on and so on. We must have the necessary tools and technology to hand before we need them.
We can't solve the problem over night, but thats the reason we should start now. There is a lot we can do. Last year, Germany produced 30% of its energy with renewables, up from 25% the previous year. As I write this, German solar produces 22 GW of solar electricity alone.
Decreasing the CO2 emissions - which wont happen due to losses in profits.
Reduce deforestation - which wont happen due to losses in profits.
Increase the planting of grasses, and fast growing carbon sequestering crops such as hemp - Wont happen because it costs money, unless its triggered by individuals (Green plants absorb infrared and sequesters CO2). For those people who say, OH! but the CO2 cycle is neutral for growing plants because they rot... B.S. what do you think permafrost is and not to mention... oil.
Seed the oceans with iron to encourage algal blooms, and dredge it all up and bury it deep.
Change the mode of Air Transport to reduce contrails as studies have suggested that ‘contrail cirrus’ is a contributing factor and leads to greater forcings. We need widespread Maglev trains, or dare I say it something revolutionary such as Hyperloop (but one that actually gets made.. lets focus on what we have already)
Less commutes == less emissions.
