Special report on climate change and land systems

from Wikipedia, the free encyclopedia

The Special Report on Climate Change and Land Systems (official German title: Climate Change and Land Systems: An IPCC Special Report on Climate Change , Desertification, Land Degradation, Sustainable Land Management, Food Security and Greenhouse Gas Flows in Terrestrial Ecosystems , English Special Report on Climate Change and Land ; SRCCL ) is a special report the IPCC ( Intergovernmental panel on climate Change , IPCC) in preparation for the 25th UN climate Change conference in 2019 (COP 25). He deals with the interactions between climate change , climate protection and human life. A executive summary was presented on August 8, 2019 and the report was posted online. About 60 scientists from all over the world were involved in the report.

content

The draft report shows that land areas have warmed globally by around 1.5 degrees Celsius since the end of the 19th century. Due to the slower heating processes in the oceans, this value exceeds the global average of around 1.0 degrees Celsius. The consequences of this overheating are already clearly noticeable. So take heat waves and heavy rain events worldwide in terms of frequency and intensity.

In the special report, the scientists urge a change in eating habits. Without a reduction in meat consumption , the climate crisis will worsen much faster. The per capita consumption of meat has more than doubled since the 1960s, which has led to a sharp rise in the demand for feed grain and protein crops (e.g. soy ). This, in turn, has increased the pressure in South America on the previously intact parts of the rainforest , which are now used as cultivation areas for animal feed .

If the world's population were to eat more plant-based and sustainably produced animal foods, several million square kilometers of land could be renatured by 2050 , according to the report. Annual carbon dioxide emissions could thus fall by 0.7 to eight gigatons.

In its report, the Intergovernmental Panel on Climate Change also recommends better protection of the forests and, last but not least, the moors in the fight against further overheating of the earth's climate system . According to the IPCC, agriculture and forestry contribute around 23 percent of man-made greenhouse gases.

Conclusion

According to Almut Arneth , one of the authors of the study, the conclusion of the study is “that we as the entire world population are currently not using the basis of life sustainably, but rather destroying it”.

Reactions

The special report aroused strong reactions from environmental organizations and politicians. These demand, among other things, a CO 2 -neutral agriculture and a reduction in meat consumption.
