On 22 September 2017, The World Climate Conference was held in Geneva signed to the Environment agreement, which regulates measures to reduce carbon dioxide in the atmosphere since 2020. Today, the Environment Agreement is the best hope for humanity to cease the heated climate impacts before reaching the point of no return of the European Union in the form of an irreversible process of frozen ice heating and thawing melting, which will increase emissions CO 2, the greenhouse effect will increase, there will be more heat and in the near future.
The agreement aims to keep global average temperature growth below 2 ° C and to make the effort to limit the rise in temperature to 1.5 ° C. However, agreement participants agreed on a precedent that peaked in CO 2 emissions, therefore, they will work on to reducing carbon dioxide emissions.
Inappropriately, not everything is so simple. Reducing CO 2 emissions may not be enough to stop global warming. This subject is analysed in the report on the technology of negative emissions developed by scientists from more than 25 countries, the members of the Scientific Advisory Board of the European Council. Therefore, the negative emissions mean clearing the atmosphere from greenhouse gases, mainly carbon dioxide. In their report, scientists once again say familiar things that, even now, the humanity is not doing enough to stop global warming. We did not even approach the accurate path to limit the warming of the atmosphere to 2 ° C.
Even worse, scientists have recently debated the theory that reducing CO 2 emissions is not enough to stop the spiral of warming. Climatologists believe that they are already in a difficult situation: there is little time left. And now, to adapt below 2 ° C, not only reduces emissions but also actively removes greenhouse gases from the atmosphere, otherwise, global warming becomes irreversible.
To make matters worse, scientists have recently been discussing the theory that even reducing CO 2emissions will not be enough to stop the heating spiral. Climatologists believe that we have already driven ourselves into a rather difficult situation – there is little time left. And now to fit into the 2 ° C framework, we will not only reduce emissions but also actively remove greenhouse gases from the atmosphere, otherwise the process of heating the planet will become irreversible.
The report analyses seven ways to remove CO 2 from the atmosphere
- The chains of vast Forest
- The rational use of soils to increase the carbon content
- The bioenergy with carbon capture and storage (BECCS)
- The confrontation through modern atmospheric (when silicates or carbonates dissolve in rainwater, CO 2 is absorbed by the atmosphere)
- The direct capture of air and carbon storage (DACCS)
- To fertilize the sea (plankton and other plants absorb CO 2 from the atmosphere and transform it into an organic substance)
- The carbon capture and storage (CCS).
For each of these technologies, scientists publish realistic analyses and forecasts. Regrettably, the forecasts are disappointing. Although to achieve this thermal barrier at 2 ° C, at least 22 billion tons of CO 2 is withdrawn from the atmosphere annually by the 2050 year to compensations. Scientists believe that, in practice, these indicators will be difficult to obtain for several reasons. For example, the rehabilitation of forest roads needed to the extent necessary for the absorption of carbon dioxide from the atmosphere, landing 330-980 million hectares of forest, or 30-65% of the arable land of human civilization.
However, it takes decades to grow forests and there is a risk of re-emission of CO 2 from fires and other problems. Examples of successful recovery include the illustration of China, that has invested more than $ 120 billion to restore 454,000 square kilometres of forest. But these are isolated examples.
Experts estimate that only a few of these options can change the size of 4 to 5 billion tons of carbon dioxide from the atmosphere. But it is a theoretical possibility. In fact, none of these options is currently promoted in the world and is not growing at a sufficient pace. It seems that the restoration of forest roads and the accumulation of carbon in the soil seem to be the easiest. But in reality, humanity is doing the exact opposite such as, it is reducing the forest and contributing to soil degradation, and for that, carbon dioxide emissions are only an increase, but not a decrease. Scientists believe that avoiding global warming will not only reduce CO emissions but also exploit the arsenal of technologies available to humanity.
