Dawn strikes the mountains rising above St. Mary’s Lake in Montana’s Glacier National Park. When the park was created in 1910, it had 150 glaciers. Now it has 30 glaciers, significantly reduced in size.
Many of the world’s freshwater glaciers are shrinking, as warming temperatures melt them away. Some have disappeared all together. The glaciers on both Mount Everest and Mount Kilimanjaro are among those glaciers noticeably decreasing as temperatures climb, causing lower-lying towns considerable worry.
Adélie penguins toddle along the ice. Inhabitants of Antarctica, these penguins are experiencing mixed impacts from global warming, depending on their location on the continent.
Global warming appears to be negatively affecting penguins living on the Antarctic Peninsula, because melting ice is decreasing the availability of food, causing the birds to swim longer distances to find sustenance. In more southerly regions, ice is melting faster, giving the penguins earlier access to food in the spring, which in turn increases their reproduction rate.
Global warming also appears to be affecting other bird species, including emperor penguins, rosy finches, and tawny owls.

Many heavily populated areas, including Florida in the U.S., are looking to their coastlines with increasing concern as sea levels rise. But perhaps none have taken it so seriously as Male. With a maximum elevation of only 8 feet (2.4 meters), any rise in sea level is likely to engulf currently inhabited ground. In response to this impending threat, the city has built a seawall around the capital.
A partly bleached coral reef is blindingly white next to healthy coral. Rising ocean temperatures, one of the many effects of global warming, are threatening coral reefs around the world. In response to the warming temperatures, a process known as bleaching occurs. Although bleaching doesn’t kill coral reefs, they become more vulnerable to diseases.
Warming oceans may also be decreasing the level of phytoplankton, a natural absorber of carbon dioxide.
In Barrow, Alaska, the northernmost U.S. town, a solitary figure walks near a snow-covered house and boat. Living 335 miles (539 kilometers) above the Arctic Circle, the 1,800 residents of this predominantly Eskimo settlement do not see the sun from late November until January.
The Poles are warming at a rate much faster than the rest of the planet. Average temperatures in Barrow have increased by 4°F (2.5°C) over the last 30 years. In western Canada and eastern Russia, temperatures are also up 4°F to 7°F over the last 50 years, a rate nearly double the global average. The warming temperatures in Siberia may dry out peat bogs, which are natural carbon sinks that can help to offset fossil fuel emissions.
A polar bear walks across rocky ground near Wager Bay, Canada. Perhaps the Arctic’s most charismatic megafauna, polar bears face serious threats from global warming. The bears depend on sea ice as a platform from which they can hunt seals, their main prey. As more sea ice melts and polar bears are left with rocky ground like that shown in the picture, hunting for food becomes increasingly difficult for these large mammals.
Like many other species, including the great white shark, polar bears appear to be moving northward as temperatures warm. Whether these species can outrun the warming temperatures is unclear, as some scientists say that global warming will lead to the extinction of millions of species, including polar bears, and many birds and amphibians, in the next 50 years.
A hurricane-damaged home in Gulf Breeze, Florida.
Thousands of Pensacola area residents were displaced from their damaged homes following Hurricane Ivan in October of 2004.
Scientists suggest that climate change may be leading to more devastating and more frequent natural disasters, like hurricanes and floods. The 2004 hurricane season may already have convinced Florida residents, as they were hit by four powerful storms between mid-August and late September.
Algae fills a pool fed by Canada Glacier in the Dry Valleys region of Antarctica. With some experts forecasting the melting of half the Arctic’s summer sea ice by the century’s end, scientists are becoming increasingly concerned about the state of the Earth’s natural air conditioner.
If Greenland’s massive ice sheets were to melt, something that could occur over the very long term, they could raise the sea level by 23 feet (7 meters).

Carbon Dioxide Increasing in Atmosphere
The atmospheric levels of the greenhouse gas carbon dioxide, have increased since pre-industrial times from 280 part per million (ppm) to 377.5 ppm (2004
Carbon Dioxide Information Analysis Center), a 34% increase. Carbon dioxide concentrations in the atmosphere are the highest in 650,000 years. Carbon dioxide is a by-product of the burning of fossil fuels, such as gasoline in an automobile or coal in a power plant generating electricity.

Efek2 Global Warming akan lebih kerasa oleh orang2 yang tinggal di tepi pantai.. Sea Level naik dan banjir pun menjadi satu hal yang tidak bisa dihindari..
Kalo gak dikurangi dari sekarang, gimana nasib anak cucu kita nanti? Masa kita mau liat mereka menderita karena ulah kita?
STOP GLOBAL WARMING FROM NOW

Saya tidak mengharapkan apa2.. Saya hanya mengharapkan kesadaran dari semua orang atas bencana besar yang akan datang ini..
Harap ditanggapi dengan baik yah..
God Bless U all..
