Answer:
Pemanasan global atau pemanasan sejagat ialah peningkatan suhu atmosfera bumi secara berterusan akibat daripada kesan rumah hijau yang melibatkan pertambahan gas kaebon dioksida , klorofluorokarbon dan bahan pencemar yang lain, yang menyebabkan peningkatan suhu dunia. Suhu bumi telah meningkat dua darjah dan kadarnya berbeza mengikut benua dan kawasan tertentu. Kajian mendapati kawasan Artik lebih pantas menjadi panas berbanding kawasan lain. Perubahan iklim biasanya berlaku dalam tempoh 10,000 tahun tetapi kini perubahan iklim berubah dalam tempoh 100 tahun sahaja, jarak hanya 2 generasi sahaja.
Suhu bumi meningkat sejak tahun-tahun 90an. Kajian mendapati iklim panas melampau di Perancis, iklim lebih panas di rantau Siberia dan pencairan "permafrost" (lapisan tanah yang kekal beku di rantau paling sejuk) terutamanya di rantau Artik. Ahli sains meramalkan keseluruhan ais laut di Artik akan cair pada musim panas 2099. Litupan ais Greenland dan Antartika Barat akan mencair . Paras laut akan meningkat kira-kira 7 meter secara mendadak.
in english
Global warming or global warming is the continuous increase in the temperature of the earth's atmosphere as a result of the greenhouse effect which involves the increase of carbon dioxide gas, chlorofluorocarbons and other pollutants, which causes an increase in global temperature. The temperature of the earth has risen two degrees and the rate varies according to the particular continent and region. Studies have found that the Arctic region warms faster than other regions. Climate change usually happens within 10,000 years but now climate change changes within 100 years only, the distance is only 2 generations. The earth's temperature has been rising since the 90s. The study found extreme hot climates in France, warmer climates in the Siberian region and the thawing of “permafrost” (the layer of soil that remains frozen in the coldest region) especially in the Arctic region. Scientists predict the entire sea ice in the Arctic will melt in the summer of 2099. The ice cover of Greenland and West Antarctica will melt. Sea level will rise about 7 meters sharply.
