    The Tunguska blast

    The meteorite that exploded above Siberia in 1908 has been credited with felling 60 million trees over 2,000 km2. Now it is being blamed for global warming. Vladimir Shaidurov of the Russian Academy of Sciences says that the impact may have disturbed the distribution of atmospheric water vapour and increased global temperatures. But the big blast wouldn't have done this, many climate scientists counter. Among other objections, they argue that the localized explosion could not have kicked off an unstoppable change in the dynamics of Earth's atmosphere.
