【機制】
地球升溫導致海冰加速融化,而冰蓋面積的縮小又加速了氣候變暖,因為更多的太陽熱量被海水吸收,而不是被冰層反射,堪稱兩者互為因果
【北極海冰】
🌡️暖化速度是其他地區三倍
🏝️相比1981 至 2010 年,今年的總面積低近 155 萬平方公里,而且平均每十年減少13.1%
🌋以目前每年40億噸的溫室氣體排放率,北冰洋的海冰估計會在未來10至30年內完全消失
【極地生態】
🐻❄️北極熊預料80年內將會完全消失
🐧皇帝企鵝將在本世紀末(2100 年)消失 80% 以上,成為「準滅絕」物種
【格陵蘭】
⛄融化比90年代快7倍,暖化超越全球水平
【海平面】
🌊上升的速度,比 1901 至 1971 年期間增加快近2倍
🌊在最理想的情境下,2100 年海平面仍可能上升 0.28 至 0.55 公尺
🏝️到2100年,馬爾地夫與威尼斯等地將會被完全淹沒
【Mechanism】
The warming of the earth leads to the accelerated melting of sea ice, and the shrinking of the ice sheet also accelerates the warming of the climate, because more of the suns heat is absorbed by the sea water instead of being reflected by the ice layer. Both are cause and effect.
【Arctic sea ice】
🌡️The rate of warming is three times that of other regions
🏝️Compared to 1981-2010, the total area this year is nearly 1.55 million square kilometers lower, and the average 13.1% reduction per decade
🌋At the current rate of 4 billion tons of greenhouse gas emissions per year, sea ice in the Arctic Ocean Estimated to disappear completely in the next 10-30 years
【Polar Ecology】
🐻❄️Polar bears are expected to disappear completely within 80 years
🐧The emperor penguins will disappear more than 80% by the end of this century (2100), Becoming a "quasi-extinct" species
【Greenland】
⛄ Melting 7 times faster than the 1990s, warming beyond global levels
【 Sea level】
🌊Rising rate, nearly twice
🌊In the most ideal scenario, the sea level may still rise by 0.28 to 0.55 meters in 2100
🏝️By 2100, places such as Maldives and Venice will be completely submerged
