2020世紀火災 Fire of the century in 2020

2019-2020年
澳洲大火

?焚燒長達7個多月
?️大火燃燒面積達1,710萬公頃
?有超過21%森林被燒毀
?估計有超過10億隻動物命喪火窟

起因
?️嚴重乾旱，降雨量已連續3年未達標
?️氣溫最高達到攝氏48.9度

影響
?釋放更多二氧化碳，加速全球暖化
?空氣污染影響附近居民健康

2020年
美國加州大火

?焚燒長達75日
?️大火燃燒面積超過127萬公頃

起因
?️多個城鎮的積雪量的降雨量，只有平均值的一半
?️多個城鎮出現超過攝氏40度的高溫（死亡谷氣溫更高達攝氏54.4度）

影響
?釋放更多二氧化碳，加速全球暖化
?空氣污染影響附近居民健康

2020年
北極西伯利亞大火

?️大火燃燒面積超過2,000萬公頃，其中1,100萬公頃為森林
?釋放了5,900萬公噸二氧化碳，比產油國挪威一年的所有碳排放量還要多

起因
?️多個城鎮的積雪量的降雨量，只有平均值的一半
?️多個城鎮出現超過攝氏40度的高溫（死亡谷氣溫更高達攝氏54.4度）
?️北極地區的平均升溫超過攝氏2度，是全球平均升溫的兩倍

影響
?導致更多北極永凍土解凍，釋放出強力溫室氣體甲烷，加速全球暖化

2020年
亞馬遜大火

?️1年內大火燃燒面積達111萬公頃
?損失約6.26億棵樹
?釋放了超過8.13億噸溫室氣體

起因
?️當地政府採取反環保政策，以推動經濟發展

影響
?釋放大量溫室氣體，加速全球暖化

2019-2020
Australia Fire

?Burning for more than seven months
?️The fire burned an area of 17.1 million hectares
?More than 21% of the forest was burned
?It is estimated that more than 1 billion animals were killed in the fire Cave

Cause
?️Severe drought, rainfall has not reached the standard for 3 consecutive years
?️The highest temperature reached 48.9 degrees Celsius

Impact
?Accelerating global warming
?Air pollution affects nearby residents

2020
California Fire

?Burning for 75 days
?️The fire burned more than 1.27 million hectares

Impact
?Release more carbon dioxide and accelerate global warming
?Air pollution affects the health of nearby residents

2020
Arctic Siberian Fire

?️The fire burned more than 20 million hectares, of which 11 million hectares were forests
? released 59 million metric tons of carbon dioxide, more than the total carbon emissions of oil-producing Norway in a year

Cause
?️The amount of snowfall in multiple towns is only half of the average
?️Multiple towns appear High temperatures exceeding 40 degrees Celsius (the temperature in Death Valley is as high as 54.4 degrees Celsius)
?️The average temperature rise in the Arctic region exceeds 2 degrees Celsius, which is twice the global average temperature

Impact
?resulting in the thawing of more Arctic permafrost, releasing the powerful greenhouse gas methane and accelerating global warming

2020
Amazon Fire

?️The area burned by the fire in 1 year reached 1.11 million hectares
?About 626 million trees were lost
?More than 813 million tons of greenhouse gases were released

Cause
?️The local government adopted anti-environmental protection policies to promote economic development

Impact
?Release large amounts of greenhouse gases and accelerate global warming
