Top 10 Concerns
|The average surface temperature has increased by about 0.6°C
(1°F). Snow cover and ice extent have decreased.
The sea level has risen by 10 to 20 cm (4 to 8").
|Greenland’s icy mountains and entire ice cap could disappear in the next 1,000 years due to global warming. If this melting occurs, ocean levels will rise by seven meters, drowning low-level coastlines around the world. View full story in Nature, April 8, 2004 or a summary at The Guardian.|
|Over the last 40 years, the rise has been 0.2-0.3 °C. Recent years have been the warmest since 1860, the year when regular instrumental records became available.||Extreme weather conditions such as high temperature, heavy rainfall, floods, droughts, etc. will also affect crop production.|
|A warmer climate will change rainfall and snowfall patterns, lead to increased droughts and floods, cause melting of glaciers and polar ice sheets, and result in accelerated sea- level rise. Rising warmth will lead to an increase in the level of evaporation of surface water; the air will also expand and this will increase its capacity to hold moisture. This, in turn, will affect water resources, forests, and other natural ecological systems, agriculture, power generation, infrastructure, tourism, and human health. An increase in the number of cyclones and hurricanes over the last few years has been attributed to changes in temperature.||Coastal areas and small islands are among the most
densely-populated parts of the world. They are also the most threatened
because of rises in sea level that global warming may cause. The heating
of oceans, and melting of glaciers and polar ice sheets, is predicted to
raise the average sea level by about half a meter over the next century.
Sea-level rise could have a number of physical impacts on coastal areas,
including loss of land due to inundation and erosion, increased flooding,
and salt-water intrusion. These could adversely affect coastal
agriculture, tourism, freshwater resources, fisheries and aquaculture,
human settlements, and health. Rising sea levels threaten the survival of
many low-lying island nations, such as the Maldives and Marshall Islands.
|There could be large decreases in the availability of water in many rivers because of rainfall and snow. The volume in others would increase due to glaciers melting, for example, the rivers originating in the Himalayas. Shifts in water availability could also affect hydropower generation, and industries such as paper, pharmaceutical, and chemical manufacturing, that use large quantities of water. Buildings and other infrastructure would be vulnerable to any increase in the frequency of storms and other extreme events, which could also disrupt transport routes.||Global warming will directly affect human health by increasing cases of heat stress.|
|Ecosystems sustain the earth's entire storehouse of species and genetic diversity. Plants and animals in the natural environment are very sensitive to changes in climate. The ecosystems that are most likely to be affected by this change are the ones in the higher latitudes, the tundra forests. Polar regions will feel the impact of warming more than others. Interiors of continents will experience more warming than the coastal regions.||Corals are known as the tropical forests of the oceans and
sustain diverse life forms.
As ocean waters in the tropics become warmer, the damage to coral reefs seems to be increasing. These corals are very sensitive to changes in water temperature, which causes bleaching. Large stretches of the Great Barrier Reef in Australia have been damaged by bleaching.
Zooplanktons, small organisms that float on the sea surface are declining in numbers, reducing the number of fish and sea birds that feed on these
|After 2100, human induced global climate change is projected
to persist for many centuries.
The sea level should continue rising for thousands of years after the climate has been stabilized.
|Is global warming making hurricanes more ferocious? New research suggests the answer is yes. Scientists call the findings both surprising and "alarming'' because they suggest global warming is influencing storms now -- rather than in the distant future.||This year is currently the second warmest on record, and could end up being the warmest once all the figures are in," Jarraud told a news conference. "It has certainly been exceptional in the intensity of its storms."|
|This stuff is hard to find. Many Government sites from many governments are placed up to throw off the truth and many truth sites are closed down.||Roughly 12,000 weather-related disasters since 1980 have caused just over 618,200 fatalities and cost a total of 1.3 trillion|
|The facts above are now updated. The Earth is heating up faster than expected. Scientist, Climatologist, Botanist, Oceanologist and a host of other specialist now have reconvened have been adding up and joining data and it is doubling the speed at which it's occurring again and again. It is said that only the people profiting and the people ignorant enough to fall prey are the ones doubting this global destruction.||Storms will be stronger and more severe. I was born in 1960. Back in the 60's & 70's we had bad storms but they were spread out, now seldom do we just get rain, we get none or a storm. Storms could go one of two ways. Few yet more powerful with long periods or Many extremely intense. Some places that were normal will become the next desert.|
