The climatologists are now set to predict long-term changes in climate.

They have stated in the magazine Nature that the success of their previous predictions has encouraged them on this venture. World is likely to face many a catastrophic consequences owing to global warming, they recently said.
In fact there is nothing new about the threat of global warming. Since long the world has been warned about the threat of global warming. What is new, however, is that the effects of global warming are likely to take effect in near future. The effects, scientists say, will be disastrous and long term.
The new research done by a group of German scientists on climate change concentrates on the effects of the excess release of Green House Gases like carbon dioxide for which human beings are directly responsible.
This research is supposed to establish a relationship between weather changes and ocean currents and is based on simulated oceanic conditions. The sudden decrease in temperature of the Pacific Ocean has generated suspicion among climatologists and they consider it to be a potent sign of global warming. However Dr. Trenberth has concluded that this is not an assured way of proving Global warming.
