Meanwhile, researchers have confirmed that the Earth could have about one-third more forests with no impact on agricultural land or cities.
In most cases, however, solutions that are very difficult to implement and expensive are used to save the climate. However, some researchers have now calculated and subsequently confirmed a method that would make the whole thing much easier and realistic. The solution is called "nature".
A study proves that the most effective way to combat climate change is reforestation. A third more forest could be planted overall without cities or agricultural land suffering. This was found by researchers from the Swiss Federal Institute of Technology in Zurich. At the university, the researchers show where new trees could grow and how much carbon could be stored by them. Planting new trees could absorb two-thirds of the climate-damaging CO2 emissions caused.
In addition, the study showed that this measure would make it possible to achieve the target set by the Intergovernmental Panel on Climate Change of limiting global warming to 1.5 degrees. The Intergovernmental Panel on Climate Change confirms that not only greenhouse gas emissions, which are harmful to the climate, must be limited by the year 2050, but that limits must also be placed on the transportation and energy sectors. Furthermore, a total of one billion hectares of land must be planted with new trees. The study showed that this would not be a problem at all.
Many trees today still have to suffer from the drought, which occurred in 2018.
Due to the drought, the forest is in danger.
At the moment, the earth has a forest area of about 2.8 billion hectares. Many researchers consider it very realistic to plant an additional 900 million hectares. This would be an area roughly the size of the United States.
The researchers, who were looking for natural solutions to climate change, deliberately ignored agricultural land and cities in their calculations. Especially Russia, the USA, Canada, China, Brazil and Australia have many areas where reforestation could take place.
The forests that were to be planted could store 205 billion tons of carbon when grown. Since the industrial revolution, about 300 billion tons of carbon have been released into the atmosphere. It can therefore be recognized that two thirds of this would be covered. The only problem is that the forests will soon have to be planted. This results from the fact that it will take several decades for these forests to mature and then completely exhaust the CO2 storage. Furthermore, the area that could be reforested is getting smaller every year due to climate change.
The study also states that many scientists assumed that tree cover was increasing. This is true in northern countries, such as Siberia. But it is not true in tropical forests. Because of this, the calculation is wrong, since tree density is about 90 to 100 percent in tropical forests and only 30 to 40 percent in northern forests.
Climate change is a stressor.

The university in Zurich has a computer on the Internet. This can be used for any place in the world. It can be used to calculate how many trees could grow in the respective location and how much carbon these trees could store.
Felix Creutzig from Berlin says that the study uses new methodological standards. This would result from the help of artificial intelligence as well as the potential of reforestation. He says it is important that the countries of China, Australia, Brazil, Canada, Russia and the United States invest a lot in additional forestation, as this is where the most trees could be planted. Indonesia and Brazil in particular, however, would first have to make sure that deforestation is stopped.
The researchers emphasize that afforestation can only be one measure of climate protection and will not stop climate change on its own. It is necessary that a rapid shift away from the fossil fuel economic model takes place. This could be achieved primarily through a cross-sectoral carbon price.
