全球气候变迁正以前所未有的速度加剧,不仅极端高温频频打破历史纪录,海洋温度、海平面上升速度及日降雨量也创下新高。科学家对气候变迁影响的严重程度感到震惊,特别是圣婴现象的到来进一步加剧了温室气体造成的暖化,并可能带来数万亿美元的经济损失。

地球的能量失衡在近年翻倍,这主要是因为地球反射回太空的阳光减少,部分原因在于海冰融化成深色海水,以及低空反射云层的流失。格陵兰与南极冰盖(如被称为「末日冰川」的史威兹冰川)的融化速度加快,已成为海平面上升的主要推手,且未来融化速度将取决于温室气体排放量。

大西洋经向翻转环流(AMOC)的减缓引发了科学家的广泛担忧,最新研究指出本世纪环流面临崩溃的机率已显著上升。与此同时,全球再生能源(如太阳能与风力)蓬勃发展且成本已具备与化石燃料竞争的优势,成为减缓暖化的关键,未来的挑战在于如何将科学数据转化为具体的决策与行动。

Global climate change is accelerating at an unprecedented rate, with extreme heat repeatedly shattering historical records, alongside ocean temperatures, sea level rise, and daily rainfall hitting new highs. Scientists are shocked by the growing severity of these impacts, especially as the onset of El Niño further intensifies warming driven by greenhouse gas pollution, threatening trillions of dollars in economic damage.

The Earth's energy imbalance has doubled in recent years, primarily because the planet is reflecting less sunlight back into space due to bright ice melting into dark sea water and the potential loss of reflective low-lying clouds. The accelerated melting of ice sheets in Greenland and Antarctica, such as the Thwaites "Doomsday" glacier, has become a major driver of sea level rise, with future rates depending heavily on greenhouse gas emissions.

The slowdown of the Atlantic Meridional Overturning Circulation (AMOC) has raised significant concern among scientists, with recent studies indicating a dramatically increased probability of collapse within this century. Meanwhile, the global boom in renewable energy sources like solar and wind power, which have become cost-competitive with fossil fuels, remains key to mitigating warming, shifting the focus to translating climate science into actionable decisions.
