5 Impact of Global Warming for EarthApr 22nd, 2011 | By wownesia | Category: News
1. The melting of the ice in the polar north & south
Global warming has a direct impact on the continued to the melting of ice in the polar regions north and south poles. Ice melting in Greenland has almost reached 19 milliontons! And the volume of ice in the Arctic in the summer of 2007, only half of which there are 4 years earlier!
The melting of ice is progressing much faster than predictive models ever created by scientists. Some early predictions that have been made previously estimated that thepolar ice caps will disappear in the years 2040 and 2100. But the annual ice datarecorded until 2007 makes them think again about the model predictions have been made previously.
The scientists acknowledge that there are key factors they had not taken within theexisting predictive models. By using the latest ice data, as well as a more accuratepredictive models, Dr. H. J. Zwally, a NASA climate expert to make new predictionsthat are staggering:
ALMOST ALL Arctic ice cap will disappear AT THE END OF SUMMER 2012!
Recently, a natural phenomenon shows how serious this condition. On March 6, 2008,an ice shelf covering an area of 414 square kilometers (almost 1.5 times the size of Surabaya) in Antarctica collapsed.
According to the researchers, plate-shaped ice blocks huge permanent floating around1609 kilometers south of South America, southwest Antarctic Peninsula. In fact, chunks of ice that is believed to be there since 1,500 years ago. ”This is a result of globalwarming,” said lead researcher Ted Scambos, NSIDC. According to him, slabs of ice called the Wilkins Ice Shelf collapsed was very rare.
Now, after the split, the chunks of ice the remaining 1950 square kilometers, 5.6kilometers plus an adjacent piece of ice and connects the two islands. ”Soon, this last chunk of ice will also disappear. And, half the total area of ice will disappear in a few years, ”said Scambos.
“Several recent events are the points that trigger the change in the system,” said SarahDas, a researcher from the Institute of Marine Wood’s Hole. Changes in Antarctica is very complicated and more isolated from all parts of the world
Antarctica at the South Pole is the continent with mountains and ice-covered lakesurrounded by the ocean. This continent is much colder than the Arctic, so the ice meltsthere are very rare, even coating that never melts in history. Average temperature of minus 49 degrees Celsius, but never reached almost minus 90 degrees celsius in July1983. No wonder if the phenomenon of melting of ice on the continent that containsalmost 90 percent around the world ice was gets serious attention of researchers.
2. The increase of sea surface level
The melting of ice at the north pole and south pole has a direct impact on sea. Scientists estimate that if all of Greenland melts, sea level will rise up to 7meters! Enough to sink the entire beach, harbor, and the lowlands around the world.
3. Climate Change / the weather get extreme
NASA states that the global warming impact on the more extreme changes in weatherand climate. The pattern of rain fall changes can be predicted without causing floodingin one place, but the drought in other places. Hurricane and tropical storm was about toemerge with a tendency more and more powerful.
Without strengthened by the statement above NASA-ever you can already see its effect on the environment around us. You certainly realize how hot the temperaturearound you lately. You can also see how it can not be predicted arrival of the rainyseason or drought which resulted in losses for farmers because planting season issupposed to do during the dry season turned out to rain. In recent years we are increasingly being hit by the storms that disrupt shipping and transport either via sea or air.
4. Heat waves become more dangerous
Global Warming cause the heat waves become more frequent and stronger. Year2007 is a new record-breaking year for the temperature reached by the usual heatwave hit the United States.
Local St. George, Utah holds the record with the highest temperature reached 48 °Celsius! Temperatures in St. George was followed by Las Vegas and Nevada that reached 47 ° Celsius, and several othercities in the United States that the average temperature above 40 ° Celsius. DeathValley region in California even had time to record the temperature of 53 ° Celsius!
The attack of the heat wave this time even forced the government in several states todeclare a state of emergency standby 1. The attacks of that year took some of the victims died (because of the heat), turn off the hundreds of freshwater fish, damagingcrops, triggering a severe forest fire, and kill livestock.
In 2003, the South European region also ever had an attack of severe the heat wavethat resulted in no less than 35,000 people died with the victims of most of France (14 802 inhabitants). France is a country with the highest casualties for not unpreparedresidents and local governments on the phenomenon of the heat wave that big. Other casualties scattered from England, Italy, Portugal, Spain and other European countries. This heat wave also caused severe drought and crop failure in the areaevenly Europe
5. Glacier ending - World Water Resources
The melting of glaciers threaten the world water supply, and in the long term willcontribute to increased levels of sea water world. And unfortunately that’s whathappened today. World’s glaciers are melting at an alarming until the point!.
NASA notes that from 1960 to 2005, the number of glaciers in various parts of the world who lost no less than 8,000 cubic meters! NASA scientists have now realizedthat the melting glaciers, melting ice at both poles of the earth, the earth’s global temperature increases, until the rising sea level is evidence that the planet is constantly being heated. And ensured that the race of men that are responsible for this.
