Is Global Warming Real?
Is global warming real? This is the question that most people are asking. But the evidence is in front of us and it's absolutely undeniable. Global warming is a very real issue. Every year, we are witnessing long-term temperature records and that is a very clear sign that the planet is warming. Richard Phillips Feynman is an American physicist known for expanding the theory of quantum electrodynamics. Here is a quote from Richard Feynman: 'The only way to have real success in science ... is to describe the evidence very carefully without regard to the way you feel it should be. If you have a theory, you must try to explain what's good about it and what's bad about it equally. In science you learn a kind of standard integrity and honesty." So lets examine the evidence which should give a clear answer on the debate whether or not global warming is real. Dr. James Hansen who works for NASA says that during the past few decades measurements of atmospheric composition - including bubbles of old air that were trapped in the ice sheets of Greenland and Antarctica as snowfall piled up year after year and was compressed into ice - these measurements show that certain trace gases have been increasing in the air during the industrial period, especially CO2 from burning of fossil fuels, coal, oil and gas. Those gases absorb heat radiation from the Earth's surface and radiate some of that heat back down, causing a heating of the surface. And this is what we call 'greenhouse effect'.
Global warming is accompanied by increasing climatic extremes. That's why in the past years, we are observing more hurricanes, draughts, forest fires, heavy rain and floods. Of course, it's true that the climate can be chaotic at any given place, but there is a very good explanation for the heavy rainfalls. Increased surface heating increases evaporation and thus rainfall, which falls increasingly in more intense penetrating convection, causing enhanced flooding. John Browne, a Chief Executive of British Petroleum (BP) made the following statement: "…science of climate change is not proven… …but there is mounting evidence that the concentration of carbon dioxide in the atmosphere is rising and the temperature of the earth's surface is increasing." If the chief executive of a petroleum company can admit that global warming is real, then what more is there to say. Is global warming real? Yes, it's very real, and we shouldn't waste any more time debating on that, instead of we should take measures to stop it. |
