The rescue of the climate would be easily possible. Why doesn’t anyone know?
The urban legends almost succeeded in establishing a feeling of powerlessness and to weaken hope: “The climate change is irreversible!”
But from a purely scientific point of view, the complete restoration of the climate can be achieved without any problems: The CO2 content of the air can be reduced to an almost pre-industrial level till 2060.
Eenewable instead of fossil
If we half the fossil energy consumption, it would save 5 Gt C/y. In particular, solar energy would be cheaper than fossil if the inhabitants of the industrialized countries would cover their energy needs with a mix of solar, wind and water energy, the available amount of energy is tens of times the currently consumed energy. Efficient and affordable solar technologies would benefit the over 4 billion people of the tropical and subtropical regions, whose energy needs can be fully covered by solar energy.
Global ban on forest destruction
16 million hectares of forest are destroyed every year, most of them tropical rainforests that absorb 500 tonnes of carbon per hectare. A global ban on forest destruction would save over 7 Gt C/y. (A sustainable use of the forests or their conversion into Agroforestry would still be possible, they do not pollute the climate or pollute it only slightly.)
Less meat
Only a healthy amount of meat: Converting one-tenth of global forage areas into forests or agroforestries would save 4 Gt C/y. (Worldwide mast area: ~ 4 billion hectares, but a new forest only starts to incorporate 10 tons of carbon per hectare after 10 years.)
The carbon difference pasture-secondary forest/agroforestry is about 250 tons per hectare, after 35 years 10 tons of wood per year and hectare can be extracted for CO2-neutral energy or as building material).
Plan AAA
If it takes 8 years to implement these “tripleA”-win-win solutions, then in 2050, CO2 would have fallen to an almost pre-industrial level:
– Only half as much fossil energy left: 160 billion tons of carbon reduction
– No forest destruction:120 billion tonnes of carbon reduction
– A tenth of all pastures to forest: 40 billion tons of carbon reduction
In 2050, the amount of carbon in the air would have dropped by 320 Gt C to an pre-industrial level. Global warming would be history.
Where there is no will, there is no way: Such scientific calculations show that economy and politics unfortunately pursue other goals than the protection of climate and mankind.
These methods cost less than the government bailouts for the financial industry, or the trip to Mars, not to mention the army budgets.
We can only prevent climate destabilization if an update of analyses reveals the key industrial strategies and missing links for the empowerment of idealists.
A trap works only as long as we don’t see the way out.
(1 Gt C = 3.67 Gt CO2 = 3.67 billion tons of CO2) (At present, the atmosphere contains about 860 Gt C, 250 Gt C less than 250 years ago, the current annual increase of 5 Gt C/y is dramatic. In the 10’000 years from Stone Age to industrialization, the total increase in CO2 was barely 100 Gt C. Calculation basis: IPCC Climate Change 2013: The Physical Science Base)
