北极海底岩芯或可厘清北极点上一次失去夏季海冰的时间
一支挪威-德国科考队正在钻取北极海底沉积物,以了解北极点在过去的温暖时期是否曾经没有海冰,这一问题与气候预测直接相关。
- 研究人员于 2025 年搭乘 Kronprins Haakon 号前往中央北极。
- 此次考察采集了最长达 22 米的海底沉积岩芯。

发表在《Science》杂志上的新研究警告称,大盐湖正在接近一个临界点,可能触发不可逆转的生态崩溃,其后果将波及整个美国西部。
New research shows Alaska's glacial lakes are expanding significantly as glaciers retreat, increasing the frequency and severity of destructive outburst floods threatening downstream communities.
A new study found that Earth's days are getting longer at an 'almost unprecedented rate' due to the redistribution of mass from melting ice to the oceans—a measurable and quantifiable consequence of climate change.
Millennia-old carbon buried in Congo Basin peatlands is seeping into blackwater lakes and rivers, raising fears that tropical peatlands may be approaching a dangerous tipping point.
A comprehensive study in Science finds climate change will dramatically increase forest fires, pest outbreaks, and windthrow across Europe through the end of the century.
New research questions whether aggressive wildfire suppression strategies are creating larger, more destructive fires by preventing the natural burns that maintain forest health.
Satellite analysis reveals Antarctica has lost nearly 5,000 square miles of grounded ice in 30 years as warming ocean waters drive retreat.
A long-standing theory that melting Antarctic glaciers could help slow climate change by releasing iron that feeds carbon-absorbing algae is being undermined by new research. Scientists studying the Southern Ocean have found the theory 'doesn't hold water,' potentially removing a silver lining from climate projections.
