Global Warming Facts - Planet Earth's Biggest Threat

Perhaps the ask that first comes in your mind is: How? How might global warming could threaten life on planet earth?

Global warming Facts 1: Melting ice in the polar north & south

News From Indonesia

Global warming has a direct impact on the prolonged melting of ice in the Polar Regions north and south poles. Ice in Greenland has melted nearly 19 million tons! And the volume of ice in the Arctic in the summer of 2007 only a half of from 4 years earlier!

The melting ice is currently running much faster than forecast models ever invented by scientists. Some early predictions have been made previously estimated that the polar ice caps will disappear in the years 2040 to 2100. But the each year ice data were recorded until the year 2007 to make them think again about the predictive models that have been made previously.

By using the most recent ice data and models is more precise prediction, Dr. H. J. Zwally, a Nasa climate master to make a new prediction astonishing:

Almost all of North Polar Ice caps will disappear in late summer 2012!

Recently, a natural phenomenon again indicates how serious this condition. On March 6, 2008, a chunk of ice exterior 414 quadrilateral kilometers (almost 1.5 times the size of the city of Liverpool) in Antarctica collapsed.

According to the researchers; slab-shaped ice a very large permanent floating colse to 1609 kilometers south of South America, south-west Antarctic Peninsula. Actually, ice is believed to be there since 1500 years ago. "This is a effect of global warming," said lead researcher Ted Scambos (Nsidc). According to him, the slab of ice called Wilkins Ice Shelf is very rare to collapse.

Now, after the separation, the remaining ices only 1950 quadrilateral kilometers, 5.6 kilometers plus the adjacent slab of ice and join together the two islands. "A petite more, the last ice will be drowned, and a half from the total area of ice would disappear in the next few years, "said Scambos.

"Some recent events are the trigger point of the ideas change," said Sarah Das, a researcher from the maritime Woods Hole Institute. Changes in Antarctica are more complicated and more isolated from the whole part of the world.

Antarctica at the South Pole is a continent with the territory mountains and lakes covered by ice which surrounded by sea. This continent much colder than the Arctic, very rare the ice melts there, even there is no coating has been melts in the history. The mean climatic characteristic is minus 49 degrees Celsius, but never reached practically minus 90 degrees Celsius in July 1983. No wonder if the phenomenon of melting ice in the continent which contains nearly 90 percent of the ice in the world have a serious attention from researchers.

Global warming Facts 2: The growth of the sea exterior level

Melting of ice in the polar north and south poles have a direct impact on rising sea levels (graph at right shows the estimation results in sea level over the last few years). Experts assessment if the entire Greenland melts, sea level will rise up to 7 meters, adequate to sink the entire beach, harbor, and the lowlands colse to the world.

Global warming Facts 3: climate turn / weather getting extreme

Nasa states that the global warming impact on the more extreme changes in weather or climate turn of the earth. Rainfall patterns turn can be expected without causing flooding in one place, but the drought in other places. Typhoons and tropical storms will emerge with a tendency more and stronger.

Without strengthened by Nasa statement on the above you can even see the effect on the environment colse to us. Do you perceive how hot the climatic characteristic colse to you lately?. You can also see how it cannot be expected advent of the rainy season or drought season which resulted in losses for farmers due to the planting season which should be done in the dry season but raining. You can also look at cases of extreme storms. In recent years, we more often affected by storms that disrupt communication via sea or air.

Typhoons in Japan and the United States continue to break new records from year to year. You can look at this facts straight through the mass media and the internet.

Global warming Facts 4: Heat Waves come to be more extreme

Global warming affect heat waves come to be more frequent and more intense. Year 2007 is the year as the new record-breaking for the climatic characteristic reached by the usual heat wave struck in the United States.

St. George, Utah held the highest narrative with the highest climatic characteristic reached 48 degree Celsius, Las-Vegas, Nevada that reaches 47 degree Celsius and several other cities in the United States with the mean climatic characteristic above 40 degree Celsius, Death Valley in California even reach the narrative with climatic characteristic of 53 degree Celsius.

The strike of heat wave even forced the government in several states to declare urgency status mode 1. This strike causes some of victims died (due to heat wave), turn out hundreds of freshwater fish, damaging crops, triggering a great forest fire, and killed cattle.

In 2003, the South European region also ever had a great heat wave attacks which causes no less than 35,000 citizen died with the victims of most of France (14,802 inhabitants). France is country with the biggest victims died due to the unprepared residents and local governments from the phenomenon of heat wave attacks. Other casualties spread from England, Italy, Portugal, Spain, and the other European countries. This heat wave also caused severe drought and crop failures prevalent in European regions.

Global warming Facts 5: End of Glacier- source of Clean Water for the World

The melting of glaciers threaten world water supply, and in the long term will contribute expanding sea water level of the world, and unfortunately that is what happened recently.

Nasa notes that since 1960 to 2005, the estimate of glaciers in various parts of the world who lost no less than 8,000 cubic meters! Nasa scientists have now realized that the melting of glaciers, melting ice at both poles of the earth, the earth climatic characteristic increases globally, and the growth of sea water level are evidence that the planet Earth continuously getting heat, and ensure that humans who are responsible for all of this. These are some facts about global warming, do you still in doubt that global warming is no ifs ands or buts happening?
