What impact will geoengineering do on biodiversity?

Geoengineering, which controls solar radiation, is a potential way to reverse the physical effects of climate change.
But according to a new study published in the British journal Nature Ecology and Evolution on the 21st, if geoengineering is half-baked, the impact on biodiversity could be two to four times more severe than the consequences of climate change.
In order to achieve the Paris Agreement's goal of rising temperatures by no more than 2 degrees Celsius, scientists suggest that large-scale removal of carbon dioxide from the atmosphere, or the use of aerosols to reflect sunlight back into space, these earth works that control solar radiation, will be effective in dealing with greenhouse gas emissions. What impact will
have on global biodiversity for geoengineering that has already been implemented but has suddenly ceased? In response, a team of researchers at the University of Maryland conducted a survey.
they compared changes in temperature and precipitation in two climate scenarios: geoengineering from 2020 to 2070, and geoengineering without geoengineering and keeping emissions at moderate levels.
study has found that rapid geoengineering has both positive and negative effects on biodiversity, but if it is abruptly terminated, the local climate will cause changes two to four times faster than climate change itself. In addition,
, in many cases, rapid geoengineering forces species to move in one direction to continue to live in similar temperature conditions, but at the same time to continue to live in similar precipitation conditions, thereby threatening ecosystems.
biodiversity-rich areas, such as the tropical oceans and the Amazon basin, are more vulnerable to negative impacts.
these results suggest that geoengineering, especially the sudden end of geoengineering, may lead to irreversible loss of biodiversity.
in a corresponding news and opinion article, scientists believe that the political debate over the earth works means that sudden start-ups and terminations are likely to occur.
most important thing for people to reduce emissions substantially to avoid extinction.
