Climate Change: Prevent or adapt

How humanity thinks about the hottest year that anyone remembers. By 2050, the extreme heat will be normal, but what is the cause?

The certificate has arrived from the "aliens": the U.S. Agency for space exploration NASA reports that 2010 is the hottest on the planet over the last 131 years.

After the record hot weather in Russia, "biblical" flood in Pakistan and catastrophic landslides and rockfalls in China, many climate scientists predict that extreme weather conditions with heating the planet to become - the usual.

NASA rating is a lot more moderate than some voices that are heard precisely from fiery Russia: this is the warmest summer - from creation of the nation! The existence of meteorological services at the time of the dukes Rjurik and Oleg, admittedly, is not known to the me.

A new study of warm weather in the U.S., issued by the National Federation of Natural History, predict that the extremely hot weather will become commonplace for the life of many who read this text - by 2050.
This private organization for studying the environment, indicates that during warming it will be increased rainfall and drought. Their climate scientist Amanda Staud, co-author of the study, said that the year 2050, this hot 2010th in fact be - normal. Cause: emissions that cause global warming.

There, again, a well-known scientific theories: the pollution caused by increasing amounts of carbon dioxide in the atmosphere, which retains heat and causes global warming - the formula of our age, which is, according to conflicting views of scientists do not yet know whether it will experience the fate " truth " that the sun revolves around the Earth.

So not all agree about the influence of the famous global warming. The list of "opposition" is lengthy. Climatologist Patrick Michaels from the Cato Institute (otherwise, close to the conservative part of American society), says that all this is mostly an exaggeration.

- All big cities will be, and already are, warmer, regardless of the release of carbon dioxide in the atmosphere. Concrete and bricks in the cities retain more heat than carbon dioxide - he said.

Us is interesting that American opponents of "ecological totalitarianism" sometimes call for help - the famous Serbian scientist Milutin Milankovich and his famous cycles. The official attitude of the authorities in the U.S. on this issue is listed on the site of the National Climatic Data Center, which operates under the U.S. Department of Commerce. It reads: "While Milankovitch cycles have tremendous value as a theory to explain ice ages and long-term climate change, is unlikely to have much impact on the decadal and century-old timeline.

And for the recent ice island breaking off, of 250 square kilometers on Greenland, some scientists blame global warming, and for others it is - normal. Jim Skiana from the National Center for monitoring glaciers, says that such a phenomenon common in the Arctic and there throughout the year is 10,000 to 40,000 thousand such ice breaking off.

Professor Andreas Minhov says that even such a large piece, for a period of 50 years is not that significant. This is the usual quantity, he says, and warns that people should not advance to make conclusions. I do not think that is a consequence of global warming.

David Bellamy, botanist and environmental activist, well known to everyone who watched the eighties curriculum on BBC, is one of those who do not believe in the theory of global warming. Therefore,  two environmental groups dismissed him from the presidency, and he argues that, that is the reason why it’s no longer on the BBC.

In two scientific camps there is no agreement even on how to confront the new, hot world. A classic, politically correct answer is that we should use clean forms of energy like solar and those generated by wind power. Patrick Michaels, however says, that these are not real solutions, because the solar energy, for example, is very inefficient and must be subsidized. He recalls that through the (pre) history, human beings always adapted to changes of the environment:

- This problem is no different from many apocalyptic threat that hovered over the human community from time immemorial, and we adapt to all these dangers…

This is the basic dividing line in relation to the future of the planet in the 21st century: will be as it must be, or, on the contrary - the better to prevent than cure. The majority opinion, at present, however, outweighs the benefit of prevention. And the earth is getting warmer ...
