OZone Layer Keeps Healing Itself

Good News! The UN agency said the hole in the ozone layer this year will probably be slightly smaller than the all-time largest of 2003, in line with the general trend of a gradual healing of the ozone layer's depletion.

"The size of this year's ozone hole is approaching an all-time high, but it will probably not break any records," said Geir Braathen, an ozone specialist at the World Meteorological Organization.

At present, the hole over Antartica is about 27 million square kilometers (10 million square miles) and the WMO expects it to increase to about 28 million square kilometers (10.8 million square miles) - a notch below its 2003 peak at about 29 million square kilometers (11.2 million square miles).

Based on previous investigations, CFC or Chlorofluorocarbons, once widely used in spray cans and refrigerators, deplete the earth's protective layer. The hole has been forming in the extremely low temperatures that mark the end of Antarctic winter every year since the mid-80s.

Based on recent patterns, Braathen expects the ozone holes to hover around this year's size for a few more years before they begin to shrink.

Some scientists predict it will take about 50 years for the ozone hole to stop forming.

TITLE: OZONE LAYER KEEPS HEALING ITSELF

ALAM BA NINYO NA ISANG PALATANDAAN NA GUMAGANA ANG SELF HEALING NG PLANETANG EARTH AY ANG PAGLIIT NG BUTAS SA OZONE LAYER NG ATING ATMOSPHERE?
INIULAT NI GEIR BRAATHEN, OZONE SPECIALIST SA WORLD METEOROLOGICAL ORGANIZATION, MAS MALIIT ANG SUKAT NG OZONE LAYER HOLE NGAYONG NTAON KUNG IHAHAMBING SA ALL TIME LARGEST SIZE NITO NOONG 2003.
SA NGAYON, ANG BUTAS NG OZONE LAYER SA IBABAW NG ANTARTICA AY NASA 27-MILYUNG KILOMETRO KUWADRADO AT ITO AY INAASAHANG LALAKI NG HANGGANG 28-MILYUNG SQUARE KILOMETERS.
BAGAMAN, MALAKI ANG PAG-ASANG GANAP NA MAGHILOM ANG OZONE LAYER HOLE, NGUNIT HINDI ITO BIGLANG MANGYAYARI DAHIL SA KAILANGAN DITO ANG 50 TAON PARA MAWALA NANG TULUYAN ANG BUTAS SA OZONE LAYER.
ANG MATINDING POLUSYON SA PLANETANG ITO LALU NA ANG CHLOROFLOUROCARBONS O CFC NA GINAGAMIT SA SPRAY CANS AT REFRIGERATORS ANG PANGUNAHING SANHI NG PAGNIPIS NG OZONE LAYER.
ALAM NAMAN NATIN NA ANG OZONE LAYER AY NAGSISILBING PROTEKSIYON NG ATING PLANETA LABAN SA MAPANGANIB NA TAMA NG ULTRAVIOLET RADIATION NA NAKASISIRA SA BALAT NG TAO AT MGA HAYOP.
ANG SINUMANG TINAMAAN NG MATINDING EPEKTO NG UV RAY NG ARAW AY MAAARING MAGKAROON NG SKIN CANCER AT KATARATA AT NAKAKAAPEKTO SA BIODIVERSITY.
