Scientists have suggested in a new research that some large-scale computer simulations may be overestimating the impact of climate change on biodiversity in some regions.
According to a report by BBC News, the researchers said models that analyze vast areas often failed to take into account local variations, such as topography and microclimates.

One of the studies looked at the fate of plant species in the Swiss Alps.
"A coarse European-scale model (with 16km by 16km grid cells) predicted a loss of all suitable habitats during the 21st Century," according to the researchers.

Co-author Shonil Bhagwat, a senior research fellow at the University of Oxford, UK, said when vegetation was looked at on a smaller scale, scientists saw a different picture.

US Still To Grapple With Health Problems Arising From Climate Change

Advances in computing power meant that more large-scale datasets were being made available to scientists, Dr Bhagwat explained.

"However, the changes in communities of vegetation occur at a much smaller scale, she added.
According to Dr Bhagwat and co-author Professor Kathy Willis, "These studies highlight the complexities that we are faced with trying to model and predict the possible consequences of future climate change on biodiversity."
The researchers called for more micro-scale studies to be carried out that complement the overall picture presented by larger models.
However, they added that the overall picture for biodiversity loss was still bleak, especially once the rate of habitat loss and fragmentation was taken into account.
"Predicting the fate of biodiversity in response to climate change combined with habitat fragmentation is a serious undertaking fraught with caveats and complexities," they observed.
