More than a billion people worldwide could starve if India and Pakistan unleash nuclear weapons because even a 'limited' nuclear war would cause major climate disruptions, a study warned.

In addition to clouds of radiation which could contaminate farmland far from the center of the blasts, the study found soot released into the atmosphere would devastate crop yields by cooling global temperatures and reducing rainfall worldwide.

The climate in northwestern Europe and the Balkans is becoming suitable for the Asian tiger mosquito, a disease-spreading invasive species, scientists said on Wednesday.

Obesity, boozing and other lifestyle risks facing teenagers in the rich world are spreading fast to counterparts in poorer countries, a probe published on Wednesday in The Lancet said.
