Scientists announced in the July 21, 1999, edition of the journal Nature findings that suggest that global warming can sometimes lead to cold weather or even a worldwide freeze. The authors conclusions demonstrate how global warming can, paradoxically, provoke a global freeze. If a modern glacier such as the Greenland Ice Sheet melts as a result of rising temperatures in the next century, it could trigger a similar flood and climate fluctuation. The ice age which had been receding for the last few centuries seems to be returning.
While many are aware of the dangers of global warming, not many know about global cooling. Scientists believe the cooling of the sun causes it. Global cooling is known for the absence of sunspot activity. According to the theory of global cooling, the sun had no sunspots between 2008 and 2009, while sunspot activity was at its peak in the 1990s. Correspondingly, this decade was the earth’s hottest since 1930.
