Bumi yang kita pinjam












 

 
Global warming is caused by the release of carbon dioxide and other heat-trapping gases into earth's atmosphere. The gases act like a thick blanket, trapping the sun's heat and causing the planet to warm up. Increase the gases and the warming increases, too. These gases are created when we burn fossil fuels in our cars and power plants as well as by loss of forests and agriculture.

Scientists find clues to global warming by studying remnants of the past in ancient glacial ice, ocean sediments as well as tree and coral rings. Global warming is problematic to human civilization because it will cause increasingly severe storms and droughts, glaciers to melt, rising seas, changes in weather patterns, and the spread of disease.
Automobiles and coal-burning power plants are the two biggest sources of carbon dioxide in the U.S. Clearing of forests is also an important source worldwide. Scientists say that unless we curb global warming emissions, average temperatures could rise by 3 to 9 degrees by the end of the century.

SURPRISING SCIENTIFIC STATISTICS ON GLOBAL WARMING

Recent data from Antarctic ice cores indicate that carbon dioxide concentrations are now higher than at any time during the past 650,000 years, which is as far back as measurements can now reach.

2005 was the warmest year on record since atmospheric temperatures have been measured. The ten warmest years on record have all been since 1990. In summer 2005, heat records were broken in hundreds of U.S. cities. Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history.

In 2003, heat waves caused over 30,000 deaths in Europe and 1500 deaths in India.

Since 1978, arctic sea ice has been shrinking by about 9 percent per decade. Seagulls were spotted for the first time at the North Pole in 2000. The snows of Mt. Kilimanjaro, at their current rate of melt, may be gone by 2020.


PREDICTED EFFECTS AS TEMPERATURES RISE

  • Global warming is predicted to increase the intensity of hurricanes. In the past several decades, the number of Category 4 and 5 hurricanes globally has almost doubled. Because the ocean is getting warmer, tropical storms can pick up more energy and become far more powerful.

  • Even as severe storms cause flooding in some areas, droughts and wildfires will increase in others.

  • Low-lying islands will no longer be habitable due to rising sea level.

  • Forests, farms and cities will face troublesome new pests and more mosquito-borne diseases.

  • Disruption of habitats such as coral reefs and alpine meadows could drive many plant and animal species to extinction

    Bumi yang kita diami ini sebenarnya kita pinjam dari anak cucu kita, jadi tanggungjawab kita lah untuk menjaga dan merawatnya sebelum kita serahkan balik kepada mereka,

Wahhh green peace kau rupanya...
Bagus juga tu, sekarang ni bumi kita betul2 panas.... tak macan 10 tahun dulu aku rasa, kalau petang masa matahari jatuh pun panas juga, lepas hujan pun panas juga, tak tau la sampai bila...
Anak cucu kita nanti tak tau la macam mana...
Ini semua akibat amalan kita yang tak betul...kita juga yg menanggung nya...
Ayuh selamatkan bumi kita...

Zam,
aku sekarang tengah belajar pantun seloka, nanti nak take over dengan karam singh waria.
