Global warming is a fantasy in the environment


Some say global warming is a fantasy in the environment. Some say it was destiny. Scientists are still pros and cons about it. To be sure, that natural phenomena can be felt in the following 10 events. And that certainly is not a mere imagination, because we've been there.

* Forest fires massive
Not only in Indonesia, a number of forests in the United States also burned ludes. In recent decades, forest fires over many areas meluluhlantakan within a longer, too. Scientists attribute this rampant fires with increasingly hot temperatures and snow melting faster. Spring came early so that the snow melts early, too. Forest areas drier than usual and more easily burned.

* Easily damaged archaeological sites
As a result of a hostile nature, a number of temples, historic sites, temples and other artifacts more easily damaged than some time ago. floods, extreme temperatures and causing tidal it all. Historic Sites 600 years old in Thailand, Sukhotai, already damaged by floods recently.

* The height of the mountain reduced
Without realizing it many people, the Alps have high shrinkage. This caused the melting of ice on top. For hundreds of years, the weight of the ice has pushed the earth's surface due to the pressure. As the ice melts, the weight is lifted and slowly lifted back to surface.

* The satellite moves faster
Carbon dioxide emissions more quickly make the planet warm, even into space impact. Terluat the air in the atmosphere is very thin, but with the increased carbon dioxide Jumah, the molecules in the upper atmosphere together more slowly and tend to radiate energy, and cools the surrounding air. The more carbon dioxide up there, then the atmosphere creates more encouragement, and the satellites move faster.

* Only the Strongest of Abiding
As a result of the growing season uncertain, the only living beings is the strong can survive. For example, early flowering plants this year, the migration of animals occur more quickly. They are moving slowly will lose food, they sementar more agile, able to survive. The same is true for all living things including humans.

* Massive Melting
Not only the temperature that triggers melting planet gununges, but also all the layers of soil that had been frozen. This melting ground trigger wrinkle causing irregular holes and damage to structures such as railways, highways, and houses. The impact of this instability on the high plains like the mountains could even cause the collapse of rock.

* Peculiarity in the Polar Region
The loss of 125 lakes in the Arctic a few decades ago led to the idea that global warming is happening more "excited" at the poles. Research around airyang source shows the possibility of missing the melting of the frozen world basis.

* Flowering plants in the Arctic
When melting Arctic trigger problems at the plant in danhewan lower plateau, also created the same situation with saatmatahari buried in the Arctic biota. Plants there is always trapped in the ice is no longer and began to grow. Scientists found an increase in photosynthetic formation of soil compared to soil surrounding the ancient era.

* Habitat Living Move to a Higher Plain
Since the early decades of the 1900s, humans had to climb in order to find lebihtinggi squirrel, beaver or forest rats. Scientists found that these animals have moved to higher ground due to global warming. The displacement of these habitats threatens the habitat of polar bears as well, because the ice where they live are also melting.

* Increased Allergy Cases
Often experience sneezing attacks and itchy in the spring matasaat, then Blame global warming. Several decades of allergy and asthma cases among the American people experienced an increase. Hidupdan pattern of pollution is considered the trigger. Scientists study showed that high levels of carbon dioxide and temperature trigger latter. These conditions also make the plants bloom earlier and produce more pollen.

Rainforest destruction accounts for 17% of global greenhouse gas emissions

Environmentalists across the world are to be enlisted as armchair detectives to monitor satellite images of rainforests and report any illegal logging.

The images will be frequently updated and anyone with internet access will be able to make instant comparisons with historical images and spot destruction of rainforest almost as soon as it happens.

Every four seconds an area of rainforest the size of a football pitch is cut or burnt down for timber and paper or to clear land for cattle and plantations.

Rainforest destruction accounts for 17 per cent of global greenhouse gas emissions, more than is produced by all the world’s cars, ships and aircraft. Tropical forests cover 15 per cent of the world’s land surface and have a double cooling effect, soaking up carbon dioxide from the atmosphere and maintaining high levels of evaporation from the canopy.

The armchair detectives will be able to report their findings to an international agency being created to monitor whether countries are meeting their commitments to reduce deforestation. Any state found to have broken its pledge will lose its share of a new global fund established by rich countries to pay nations for leaving their trees standing.

The fund, called Reducing Emissions from Deforestation and Forest Degradation (Redd) and worth up to $30 billion (£18 billion) a year, is due to be approved at the UN climate change summit in Copenhagen next month.

Google is helping to create the new online detective tool, which is likely to be launched next year. Philipp Schindler, from Google UK, said: “Our engineers are exploring how we might contribute to this effort by developing a global forest platform that would enable anyone in the world, including tropical nations, to monitor deforestation and draw attention to it.”

Mr Schindler was speaking yesterday at a seminar on deforestation hosted at St James’s Palace by Prince Charles and attended by leaders and ministers from several of the largest rainforest countries.

President Jagdeo of Guyana told the seminar that the cheapest way for industrialised countries to reduce carbon emissions was to pay poor countries, such as Guyana, not to fell their trees.

Contributors to the Redd fund will pay about £4 for each tonne of CO2 saved by reducing the rate of deforestation. Fitting carbon capture and storage systems to coal-fired power stations costs more than £50 for each tonne saved.

Norway announced last week that it would demonstrate how Redd could work by paying Guyana up to £150 million over five years to preserve its trees.

Guyana’s forests have been far less logged than in many tropical nations, and under the terms of the new deal with Norway, Guyana could actually be paid for increasing deforestation. The memorandum states that Norway will compensate Guyana if it does not cut down more than 0.45 per cent of its forests per year, but Guyana is currently felling trees at a far slower rate. The countries contributing to Redd are concerned that their money could disappear into the pockets of corrupt officials in poorly governed countries. There are also fears that payments will result in logging companies switching to unprotected areas, resulting in no net reduction in deforestation.

Per Frederik Pharo, of the Norwegian Government’s forest protection fund, said payments would only be made when countries could prove that they had reduced their annual rate of deforestation by an agreed amount. He said the targets would be raised every five years.

Brazil has halved its rate of deforestation in the past year but Tasso Azevedo, of Brazil’s Forest Service, warned that it could increase again unless the country received substantial sums of Redd “People have to have some income and we need a lot of cash for the community to maintain the forest,”he said.
