Climate Change: Biodiversity Scenarios

Climate Summit 2021 | Global Climate Events | Climate Congress | Global Warming Meetings

 

Change in climate has consequences on the biophysical environment such as changes in the start and length of the seasons, glacial retreat, decrease in Arctic sea ice extent and a rise in sea level. These changes have already had an observable impact on biodiversity at the species level, in term of phenology, distribution & populations, and ecosystem level in terms of distribution, composition & function. In terms of ecosystems, there has been some evidence on changes in distribution. e.g. desert ecosystems have expanded, and tree lines in mountain systems have changed. As biodiversity underlies all goods and services provided by ecosystems that are crucial for human survival and well-being, this paper synthesizes and discusses observed and anticipated impacts of climate change on biodiversity and biodiversity-based ecosystem service provision and livelihoods, and what strategies might be employed to decrease current and future risks on the well-being of human life.
