Global warming

Opening a cycle of articles about the basic problems of the Earth, first of all we will pay attention to the greatest, but inconsistent enough, giving in to criticism, and sometimes even almost not exciting theme of global warming.


Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation. According to the 2007 Fourth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC), global surface temperature increased 0.74 0.18 C (1.33 0.32 F) during the 20th century. Most of the observed temperature increase since the middle of the 20th century was caused by increasing concentrations of greenhouse gases, which results from human activity such as the burning of fossil fuel and deforestation. Global dimming, a result of increasing concentrations of atmospheric aerosols that block sunlight from reaching the surface, has partially countered the effects of greenhouse gas induced warming.

Climate model projections summarized in the latest IPCC report indicate that the global surface temperature is likely to rise a further 1.1 to 6.4 C (2.0 to 11.5 F) during the 21st century. The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions. An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice. Other likely effects include changes in the frequency and intensity of extreme weather events, species extinctions, and changes in agricultural yields. Warming and related changes will vary from region to region around the globe, though the nature of these regional variations is uncertain. Another major worldwide concomitant of global warming, and one which is presently happening as well as being predicted to continue, is ocean acidification, which is likewise a result of contemporary increases in atmospheric carbon dioxide.

The end of quotation.

Even if it is a far-fetched problem and rise in temperature it is connected with an integral part of the life of the Earth, let's not to forget about that place where we live.

The problem of global warming already now forces us to think of an effective using of any kind of energy, about that for what we use it and as. We not only should remember alternative energy sources, but also introduce these decisions in practice. We shouldn't be lazy to prefer to the car a bicycle and to know that road to work with the "bike", it isn't a shame, and on the contrary very much even it is useful. We are engaged every day in business, but the person receives the great pleasure from the simple help to another.

We are people. And what problems would be not pursued by the person, what purposes wouldn't face it, he should remember that his life, it first of all a place where he lives.

Let's build our planet as strong together!
