Yale Study: Not Enough Metals In Earth To Meet Global Demand

Researchers studying supplies of copper, zinc and other metals have determined that these finite resources, even if recycled, may not meet the needs of the global population forever, according to a study published in the Proceedings of the National Academy of Sciences.

According to the study, even the full extraction of metals from the Earth's crust and extensive recycling programs may not meet future demand if all nations begin to use the same services enjoyed in developed nations.

Astronomers find Earth lookalike

Twenty thousand light years away, in the constellation of Sagittarius near the centre of the Milky Way, a frigid rock is orbiting a small star. Although the distant world is probably too cold ever to support life, scientists believe it is the most Earth-like planet to be discovered beyond our solar system.

Known to astronomers as OGLE-2005-BLG-390Lb, the planet, described in Nature today, is five times as dense as Earth and orbits its sun at three times the distance Earth is from our own star, leaving surface temperatures at a frosty -220C.

Baffled Scientists Say Less Sunlight Reaching Earth

After dropping for about 15 years, the amount of sunlight Earth reflects back into space, called albedo, has increased since 2000, a new study concludes.

That means less energy is reaching the surface. Yet global temperatures have not cooled during the period.

Increasing cloud cover seems to be the reason, but there must also be some other change in the clouds that's not yet understood.
