Človeštvo se sedaj bojuje, da dvig tempretature ne bo večji kot 2 stropinji (2 stopinji sta menda namrec že neizbežni)!
Mogoče se vam zdi, da se to nas ne tiče, ko v vsakodnevnem življenju ne občutite večjega pomanjkanja. Toda ravno mediteran naj bi bil med tistimi kraji na zemlji, ki naj bi bil močno prizadet zaradi vročinskih valov in dviga temperature!
What would happen if the earth's temperature increased by 1°C (1.8°F)? There is no clear way to predict what would occur, but scientific research and climate models indicate some serious changes to out climate.
Earth's climate has increased less than a degree of warming, but as researcher/author Mark Lynas outlines in his book "Six Degrees", there are some potentially drastic effects in store for earth's climate.
Our World Plus:
1°C ------------------------
° Severe droughts in the western United States could cause shortages in global grain and meat markets.
° Arid regions of the western United States could revert to desert-like environments.
° New deserts could emerge in the western half of the United States, from Texas all the way up to the Canadian border.
° The Arctic could be ice free for half the year, opening the legendary Northwest Passage for ships.
° Rising tides could submerge thousands of homes around the Bay of Bengal.
° An increase of 1 degree Celsius may cause hurricanes to begin hitting the South Atlantic.
° An increase of 1 degree Celsius may inspire an agricultural makeover in England, as crops previously unable to survive in the United Kingdom begin to thrive. The United Kingdom now has more than 400 vineyards, growing grapes that have typically been grown in France.
2°C ------------------------
° Insects may migrate in strange new directions. For example, as a temperate climate moves north in the United States, pine beetles could kill off the great whitebark forests.
° Greenland's glaciers continue melting at a faster rate. In fact, Greenland's Jakobshavn Glacier is already the fastest-moving ice field on the planet; the amount of ice breaking off the glacier every few days contains enough water to supply New York City for one year.
° Because of a decrease in sea ice, polar bears make the endangered species list.
° Forests begin to take root in Canada's melting tundra.
° The Pacific islands of Tuvalu could sink beneath the rising ocean tides.
° At 2 degrees of warming, the impact on the marine ecosystem is likely to be severe, and it is possible that the vast majority of the world's tropical coral reefs will die off.
3°C ------------------------
° Many scientists focus on 3 degrees of warming as the tipping point that will fundamentally change how we live on this planet.
° In the extreme conditions of a world warmer by 3 degrees, the Amazon rain forest could experience repeated cycles of drought and fire. If we lose much of the Amazon, it could cause the re-release of hundreds of millions of tons of stored carbon, perhaps intensifying global warming another degree all by itself.
° An increase of 3 degrees Celsius causes the snowcaps on the Alps to all but disappear.
° The Mediterranean and parts of Europe wither in searing summer heat.
° As the oceans get hotter and hotter, a new global climate pattern emerges that is unstable in the extreme, perhaps mirroring the weather anomaly we call El Niño.
° If the planet warms by 3 degrees, the world could see the next generation of superstorms, the first Category 6 hurricanes.
° Thousands of species worldwide would face extinction.
4°C ------------------------
° An increase of 4 degrees Celsius causes the oceans to continue to rise, overtaking heavily populated deltas. Countries like Bangladesh and Egypt could be devastated, and cities like Venice could be totally submerged.
° The Ganges River is the wellspring of life for over a billion people in China, Nepal and India. At first, the melting of Himalayan glaciers that feed the Ganges might unleash unprecedented floods. But then, extreme water scarcity and famine could strike if the glaciers vanish completely.
° Studies suggest that at the current rate of loss, there will be no more glaciers in the Himalayas by the year 2035.
° Northern Canada may become one the planet's most bountiful agricultural zones
° The entire West Antarctic Ice Sheet could collapse, sending sea levels rising even further.
° At 4 degrees of warming, sea levels could be rising by more than 1 meter, as the world's great coastal cities prepare for catastrophe.
5°C ------------------------
6°C ------------------------ izumrtje človeške vrste, kakor večine živalskih vrst
