'Science Express' redesigned as SECAS, intends to contribute towards increasing understanding of the science of climate change, the observed and anticipated impacts and different possible responses.

Thus it was rational to shift the focus to the theme 'Climate Change' as it will affect the biodiversity of not just India but the entire globe as well.
