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.
