　　Can you imagine a world where more than half of our common plant species and a third of our known animals disappear from sight? That's thescenariosuggested by new research on the impact of climate change.

　　An international team of researchers looked at the impact of rising temperatures on nearly 50,000 species of plants and animals. Theycame to the conclusionthat these are to decline due to changes in their habitat.

　　They looked at temperature andrainfall recordsfor the habitats in which these species now live, andmappedthe areas that would remainsuitablefor them under differentweather conditions.

　　The scientists projected that if no significant efforts were made to limitgreenhouse gas emissions, by the year 2100 global temperatures would be 4C abovepre-industrial levels. In this scenario, some 34% of animal species and 57% of plants would lose more than half of their current habitat ranges.

　　The impact on species will be felt more heavily in some parts of the world such as sub-Saharan Africa, Central America, the Amazon region and Australia.

　　Our society would be affected too, according to Dr Rachel Warren, from the University of East Anglia in Britain. She says: "There'll be aknock-on effectfor humans because these species are important for things like water andair purification, flood control andnutrient cycling, and eco-tourism."

　　In spite of the conclusions to thispaper, published in the journal Nature Climate Change, it is not alldoom and gloom. Dr Warren says: "Swift action to reduce CO2 and othergreenhouse gasescan prevent thebiodiversityloss by reducing the amount ofglobal warmingto 2C rather than 4 degrees."

　　The researcher believes that this wouldbuy timefor plants and animalsto adaptto the change.

　　If nothing is changed and the predictions of this study are confirmed, the world might look very different in a few generations.
