UN scientists said the world needs to work together on the crisis of climate change and species loss and take steps to correct both, not just one, in order to save the planet.
A joint report on Thursday by separate UN scientific organizations investigating climate change and biodiversity loss found that there were ways to attack two global problems at the same time, but with some corrections to global warming. May accelerate the extinction of flora and fauna.
For example, measures such as expanding bioenergy crops such as corn and efforts to extract and bury carbon dioxide from the air could use twice as much land as India, so the impact is “biodiversity”. It’s pretty devastating to sexuality. ” Almut Arnes, a biologist and co-author of the Karlsruhe Institute of Technology in Germany, said.
Co-author Pamela McElwee, a human ecologist at Rutgers University, said policy responses to climate change and biodiversity loss have long been siloed, with different government agencies responsible for each. It was.
Scientists said the problems worsened, entwined, and ultimately hurt people.
“Climate change and biodiversity loss threaten human well-being as well as society,” said Hans Otto, a German biologist who assists in overseeing the UN Intergovernmental Panel on Climate Change Impact Group. Co-Chair of the Portner Report said.
The Earth’s naturally changing climate shaped the development of life, including humans, but when people in developed countries began pumping fossil fuels into the air, it caused a chain of problems, Portner said.
“It’s time to fix what we were wrong,” he said. “The climate system is not on track and biodiversity is suffering.”
According to the report, there are many measures that can address both issues at the same time.
Pete Smith, a plant and soil scientist at the University of Aberdeen, said “protecting and restoring high-carbon ecosystems such as tropical forests and peatlands” should be a top priority.
Some climate solutions can increase species loss, but scientists have said that efforts to control extinction do not actually harm the climate.
Junne Singh, principal investigator of the French National Institute, said that most of the measures taken to protect biodiversity also help control climate change. While praising the growing interest in nature-based solutions, she said conservation measures “need to be accompanied by a clear reduction in emissions.”
“This report is an important milestone,” said Simon Lewis, chairman of the Global Change Sciences at University College London, which was not part of the report.
“Finally, the world’s organizations that integrate scientific information on two of the two most serious crises of the 21st century are working together,” he said. “Preventing biodiversity loss is even more difficult than phasing out the use of fossil fuels.”
