Global Warming???

I had been to different places recently. There is a huge fuss about global warming. But i have noticed that the temperature is not only rising in summer, it is also dropping a lot in winter. Recently there had been train accidents due to fog in UP.

Where is this climate leading the whole mankind? With the temperature going into both extreme ends, people are finding it difficult to cope up with the huge temperature difference. Hot waves in summer and cold waves in winter are becoming more predominant.

In which direction is mankind moving to? "The Day After Tomorrow"? We hope not!!!
