Add one billion hectares of forest to our planet, this could promote the good management of global warming.
Global warming is nothing but the result of an excessive concentration of greenhouse gases on our planet. The CO2 emissions are increasing from year to year, but it will not rely on technology to capture and limit.
Technological techniques are not miracle solutions
Using technology to fight global warming could have been a solution. Several methods exist that allow reforestation or the direct extraction of CO2 from the atmosphere, but these negative emission technologies are not really sufficient.
According to a report from the Consultative Council of Academies of European Sciences (EASAC), " Emissions-producing technologies may have a useful role to play, but on the basis of current information, not at the levels needed to compensate for inadequate measures of reduction. emissions ".
Emissions-free technologies are therefore not a miracle solution at the moment, but what about trees?
0.9 billion hectares of forest to take hostage two-thirds of the carbon emitted by humans for three centuries
Forests are a natural ally in the fight against global warming. According to a report produced by an intergovernmental panel of United Nations climate change experts, it would be wise to add exactly 0.9 billion hectares of forest to our planet to capture much of our carbon emissions. That would catch 250 gigatonnes of carbon emitted, about five times the amount we issued last year.
This immense forest the size of the United States made it possible to limit global warming to 1.5 ° C by 2050.
Less global warming, but not that ...
The growth of such a large forest would not only trap carbon. It would also offer high biodiversity, improved water quality, and erosion.
The total cost of this almost billion hectares of forest could amount to $ 300 billion, at a price of $ 0.30 a tree.
