Global warming affects human beings in all aspects of their lives and its harmful effects are rampant throughout the world. In my view, climate change is the most severe problem we are facing today – even more serious than the threat of terrorism. The predicted effects for the environment and for human life are numerous and varied. The main effect is an increasing global average temperature. The list of dangerous effects are so long that it would be impossible to state all of them.
To make you all aware of just how serious global warming is, I want to tell you some unknown and harsh facts about it. The year 2005 has been recorded as the world’s hottest year and the world’s 11 warmest years have been recorded since 1990. The current levels of carbon dioxide is over 380 ppm, higher than it has been in the last 6,50,000 and is showing no signs of decreasing. The average temperatures around the world have risen by more approximately 3 to 4oC in the last score years. Lakshadweep and Colaba in Mumbai are expected to be wiped off the world map in 25 years if the sea levels continue to rise at the present rate. Worldwide more than 10 crore people live within 3 feet of mean sea level and the lives of all these people are endangered. Many species could be hit hard—including humans. The only people who can be blamed for all these tribulations are we, ourselves.
It is time for us to take some swift action to reduce global warming or our actions will lead to our own destruction. We really don't have a policy on climate change. There's a lot of rhetoric and not a lot of action. Each of can play a role in dealing with and slowing climate change. Each of us must. Right now, the best source for practical actions that can be adopted by individuals, groups, cities, businesses, and governments are various. As responsible global citizens, we can take several steps to reduce the emission of greenhouse gases and thus global warming like we can use public modes of transports, carpools. We can use cleaner and more efficient vehicles, use renewable energy like solar or wind energy as far as possible as they are eco-friendly. I appeal to you to take steps to reduce global warming as it is predicted that there may not be more than four generations of human beings.
Let me end by saying that global warming is no longer a doomsday prophecy, it’s a reality. Everybody talks about the changing weather but nobody does anything about and if nothing is done, we will soon be crossing the thresholds into climatic hell.
