But mapping inaccessible mountainous terrains like the Himalayas is a challenge. A scientific team claimed studying the climatic history of a region can help locate species-rich areas.

With the world in economic recession, there is a temptation to downgrade or sideline climate change. That would be a great mistake.
The gathering of 2,000 scientists in Copenhagen in March found the climate change situation much worse than previously reported. They called on politicians to act quickly and decisively.
