تبدال د لمناخ

أمتلة ديال لمفعول د التبدال د لمناخ: حرايق د لغابات بسباب السخونية، التبياض ديال لمرجانات لبحرية بسباب لحرارة، و جفاف حادّ بسباب قلة لما.

ف التخدام لعام لمصطلح ديال تبدال د لمناخ climate change كيوصف التسخان لعالمي global warming لي هوّ الطلوع د لموعدّال د لحرارة د لأرض، لي عبروه لعولاما، و بدا كيحس بيه بنادم د لقرن 21. التبدال د لمناخ ف معنى أعم كيتّقصد بيه التبدال لي طرا ف فترات قديمة د لأرض و على مدى زماني كبير. الزيادة لحالية ف لموعدال د لحرارة غادية ب زربة كبر من لفترات لي سبقو، و سبابو بشكل أساسي هوّ النشاطات د بنادم بحال لحريق ديال نواع لفيول بحال لپيطرول.^[2]^[3] التخدام ديال لفيولات لفوصيلية fossil fuels، التقلاع د لغابات deforestation، و بعض لممارسات لفلاحية و الصناعية كاتساهم ف لڭازات د بيت لغرس greenhouse gases سيرتو تاني ؤكسيد لكاربون و لميطان.^[4] لڭازات د بيت لغرس كايمتصّو السخونية من الشعا د الشمش لي كينعاكس على لأرض، و هادشي كيخلي لكوكب يبقى يسخن كلما تراكمو هاد لڭازات ف الجو.

التبدال د لمناخ عندو تأتير متزايد على لبيئة بحال التوساع ديال الصحاري و الزيادة ف عدد لحرايق د لغابات.^[5] ف لمناطق لقطبية لمقدار ديال الجليد غادي و كينقص.^[6] درجات لحرارة الطالعة كاتسبب ف عواصف قوية، جفاف، و شكال خرين ديال الطقس لحادّ.^[7] التبدال ف لبيئة ديال الجبال، لمرجانات لبحرية، و لمناطق لقطبية كاتفرض على النواع لحية باش تهاجر ل مناطق جديدة ؤلا تنقارض.^[8] وخا ينجح بنادم ف توقاف التبدال د لمناخ، لمفعول ديالو غادي يبقى ل قرون جايين، بحال السخونية د لمحيط، التحميض ديالو، و الطلوع د لمستوى د لبحر.^[9]

التبدال د لمناخ كيهدد بنادم ب فيضانات، سخونية طالعة بزاف، قلة لماكلة و لما، لأمراض، و خسارات قتيصادية. لهجرة د بنادم و الصراعات على لموارد بحال لما تقدر تزاد بشكل كبر.^[10] لمونضامة لعالمية د الصحة كاتعتابر التبدال د لمناخ أكبر خاطار على الصحة ف لعالم ف لقرن 21.^[11] لمجتمعات لفقيرة هيّ أقل وحدة كاتساهم ف التبدال د لمناخ، و ف نفس لوقت أكتر وحدة معرّضة ل لمخاطير ديالو.^[12]^[13]
