Climate change will have a major impact on life on earth over the next 30 years. This will lead to malnutrition, lack of water, many species will disappear, shows a draft report of the Intergovernmental Panel on Climate Change (IPCC), a UN body, quoted by AFP.
Even if the reduction in greenhouse gas emissions continues, climate warming will accelerate dramatically by 2050.
“Life on Earth can be restored after major climate change, evolving into new species and creating new ecosystems. Mankind cannot,” says the study, which seeks to reduce global warming.
The 2015 Paris Agreement provides for the limitation of global warming to 2 degrees Celsius, but the IPCC did not want to exceed 1.5 degrees Celsius.
The World Meteorological Organization estimates that the threshold of 1.5 degrees Celsius over a year will be exceeded by 2025 by 40%.
“The worst is yet to come, with far greater implications for the lives of our children and grandchildren than for us,” the report said.
Some animal species and plant mice will disappear. These are many animals in Africa because the weather there heats up three times faster than average. Agriculture, animal husbandry, fishing, aquaculture will be affected.
“Even at + 1.5 degrees Celsius, living conditions will change beyond the ability of certain organisms to adapt. Current levels of adaptation will be insufficient to respond to future climate risks,” the document said.
At the same time, another 80 million people will suffer from hunger by 2050 and 130 million will reach extreme poverty in the next 10 years. Hundreds of millions of people living in coastal cities will be threatened by floods due to rising sea levels, which will cause mass migration.
In addition, about 400 million people will suffer from lack of water and another 420 million people will suffer from extreme heat.
Some areas, such as eastern Brazil, Southeast Asia, central China and coastal areas will suffer three to four simultaneous weather disasters, such as: heatwave, drought, cyclone, fires, floods, mosquito-borne diseases.
To all this are added the effects of human activities, ie habitat destruction, overexploitation of resources, pollution, spread of diseases. Climate change will also lead to extreme human behavior, such as escalating violence.
The rise in temperature by more than 2 degrees Celsius will lead to the melting of ice caps in Greenland and western Antarctica, which will cause a rise in sea level by 13 meters. Moreover, the Amazon basin could turn into a savannah.
Some of the solutions concern measures taken to expand mangrove forests and underwater kelp forests that increase carbon storage, protect from floods and provide habitat for species and food needed by coastal populations.
The report will be officially published in February 2022.
