"The climate is changing, and it's changing at an unprecedented rate. Whether it's a natural cycle, or whether humans are the cause, we have to recognize that this is happening," said Demain, who added, "Every small step [such as using compact fluorescent bulbs or driving less] is important.

Earth likely to disappear in two centuries, warn "experts"

If the phenomenon of global warming is allowed to continue at the current rate, the human race is likely to be wiped out in about two centuries by disaster if not earlier by a nuclear war, Professor Syed Amir Ahmed Kazmi, former Director General, Pakistan Meteorological Services told The News.

Prof. Kazmi’s theory based on thorough research has been seconded by the renowned British Scientist Dr Stephen Hawking, who advised developed nations while addressing a press briefing in London in 2006 that “they should, within the next 50 years select a suitable planet or star for settlement of the next human race. USA has already taken initiative in this direction. The Kepler Telescope recently launched by National Aeronautics and Space Agency (NASA) for a three-year period is meant to find a similar Earth-like planet in the Milky Way Galaxy with the right temperature and water for the survival of life.” [Via Climate Depot]
