climate change and global warming

Climate change and global warming

The climate is changing . The earth is warming up there is now overwhelming scientific consensus  that it is happening and human induced. With  global warming on the increase and species and their habitats on the decrease chances of Eco-systems to adopt naturally are diminishing.

Many are agreed that climate change one of greatest  threats facing the planet. Recent years show increasing temperatures in various regions and or increasing extremities in weather pattern.

For many years, large influential businesses and governments have been against the idea of global warming . Many have poured lot of resources into discrediting what has generally been accepted for a long time as a real.

Now the main stream of generally worried about climate change impacts and the discourse seem to have shifted accordingly. Some businesses that once engaged in disinformation campaign have even changed their opinions some even requesting governments for  regulation and direction on this issue. However  a few  influential companies and organizations are still attempting to undermine climate change actions and concern. For number of years there have been concern that the climate change negotiations will essentially ignored a key principal of climate change frame works : the common but differential responsibilities.

This recognizes that historically
. Industrial nations have emitted far more green house gas emission ( even if some developing nations are only now increasing their.)
.. Rich countries therefore face biggest responsibility and burden for action to address the climate change.
.. Rich countries therefore must support developing nations adopt, through financing and technologies transfer for examples.

This actions of “ climate justice “ is typically ignored by rich nations and their main stream media, making it to blame china and India and other developing countries for failures in  climate change mitigation negotiations.

Development expert Martin Khor, calculated that taking historical emissions into account, the rich nations owe  a “ carbon debt”  because they have already used  more than their fair quota of emissions.

It is likely that rich countries will emit 200 gig tons of carbon more than what it would under fairer allocation ( that is there will be likely emit a total of 325 giga tons  out of maximum 600 gt by 2050.)

However rather than continue down the path of unequal development  industrialized  nations can help pay off their “ carbon debt” by truly helping emerging countries develop along a clean path , such as through the promised but -barely delivered technology transfer, finance and capacity building.

So far however rich nations have done very little within the Kyoto protocol to reduce emission by any meaningful amount, while they are all negotiating a follow on treaty that brings more pressure to developing countries to agree to emission loggers.

In effect  the more there will be delay the poor nations will have to save the earth with their sacrifices (and if it works an history shows, the rich and powerful will first away to  rewrite history to claim they were the ones that saved the planet.

Global temperatures change has been an issue for long back but present scenario this issue has emerged as havoc for developing world by developing countries to drive political and economic motives . Prof. Rafiq Ahmed department of geography and earth science university of Wisconsin U.S. said that some scientists believe that the prediction of climate changes are to be pessimistic  and unrealistic because computer predictions based on present day data. He further added that the temperature rises when green house gasses like carbon dioxide , water vapor methane and nitrous oxide trap heat and light from sun in the earth atmosphere and effect human, animals and plants.

Prof . Farasat Ali  Siddique chairman and coordinator  department of geography said that according to U.S. global change research program-me global warming is unequivocal and last 5 decades is primarily because human induced emission of heat trapping gasses like coal, oil and gas along with clearing forests, changing in agriculture practices and other activities. He said that the department is planning to start applied geography program-me under a scheme so that such issues should be investigated more deeply and intelligently  for developing countries  awareness not only among educated but also laymen to make them understand the severity of global warming and its effects.

Extreme Winter Weather Linked to Climate Change

This winter’s heavy snow falls and other extreme storms could well be related to increased moisture in air due to  global climate change as panel of scientists said recently.

The extreme moisture is likely to bring on extra ordinary  flooding with onset of spring in the northern Hemisphere , as deep snow pack melts and expected heavy rains add to seasonal run off the scientist said in a telephone briefing.

As planet warm up, more water from oceans is evaporated into atmosphere said Todd Sean Ford a climate scientist at union of concerned scientists. At same time because the atmosphere is warmer, it can hold onto more of moisture that it takes in.

Intense storms are often the result when the atmosphere reaches to saturated point Sanford said. This year, a series of heavy storms over the U.S. Mid west is north east have dropped up to 400 percent of average snows in some locations said Jeff Masters director of meteorology at weather under ground.

“ if you were to take all that water and melt it, it would come out of more than 6 inches over large swaths of the area “ Maters said . If all that water gets unleashed in hurry, in a sudden warming, and some heavy rains in the area” . we could be looking at record flooding along the upper Mississippi river and red river in north Dakota that tallies projections by U.S. Weather service, which last month said  a large stretch of north central United States is that at risk of moderate major flooding in this spring.

Spring creep

Spring floods could be exacerbated by spring creeps a phenomenon where spring creeps begins earlier than previously.

“We have documented in mountains of U.S. West the spring run off pulse now comes between one and three weeks earlier than it used to 60 years ago “ Masters said . “And  that’s because warmer temperatures  tending to melt that snow pack earlier and earlier “ .

In the last century global average temperature have risen by 1.4 degrees Fahrenheit 8 (Celsius) last year  tied for the warmest in modern record. One place this warm the shown up was in Arctic, which is a major weather maker for northern Hemisphere according to Mark Serreze  director of U.S. national snow and ice data centre.

One driver of this winters “crazy weather” Serreze said, is an atmospheric  pattern known as “ Arctic Oscillation which has moved into what climate  scientists call a negative phase.

This phase means there is a high pressure over Arctic and low pressure at  mid -latitudes, which makes Arctic zone relatively warm but spills cold Arctic air south word  to place like the U.S. Midwest and north east.

The negative Arctic oscillation has been evident for two years in row, the same two winters that have had extreme storms and heavy  snow falls.

It is possible but not certain, that negative Arctic oscillation is liked to warming of Arctic which is in turn influenced by decrease in sea ice cover throughout the region.

The only underlying explanation for these events in climate warming due to heightened green house gas levels Serreze said.

By above weather conditions we can understand entire global weather patterns trying to change in the atmospheric conditions due to global warming. This to under stand for laymen to know about climate change and that  causing global warming effecting humans animals and plants . We being citizens of this society to we should aware  about global warming and take necessary precautions for reducing green house gases and adopting climate conditions favorable for human survival on this planet ..
