It can not be denied that the world in which we live has undergone drastic changes, and the most significant of them is the so-called global warming. Some attributed it to the end of the Mayan long count calendar which will take effect Dececemder 21, 2012, winter solstice of that year. It is said that a global catastrophe will happen on that day. Planet-x (is it the Nibiru of ancient Babylonians?) will collide with our planet. Polar reversion will take place causing floods and earthquake of great magnitude, and many more, (Incidentally, the winter solstice for this year is today, December 21.)
Some see it in a biblical point of view saying it is the sign of the wrath as stated in Revelation 6:1-17.
Whatever it is, one thing is sure. The cause of the changes in our climate is largely caused by excessive greenhouse-gas emissions from highly industrialized countries thus triggering global warming. That is why delegations from 193 nations gathered in Copenhagen last December 7-16 aiming to reach a new global agreement on climate change.
