Para peneliti di Columbia University telah mengidentifikasi mekanisme tepat mengenai bagaimana peningkatan kadar karbon dioksida mendinginkan atmosfer bagian atas. Temuan ini menjelaskan pendinginan stratosfer yang telah diamati selama beberapa dekade di tengah pemanasan permukaan bumi. Studi mereka diterbitkan dalam jurnal Nature Geoscience.

Stratosfer, lapisan yang berada di antara sekitar 11 hingga 50 kilometer di atas permukaan bumi, telah mendingin sekitar 2 derajat Celcius sejak pertengahan 1980-an. Pendinginan ini melebihi sepuluh kali lipat dari jumlah yang diperkirakan jika tanpa adanya emisi karbon dioksida oleh manusia. Proses ini pertama kali diprediksi pada tahun 1960-an oleh pakar klimatologi Syukuro Manabe.

Ancient Antarctic ice reveals modest greenhouse gas changes over 3 million years

Scientists analyzing ancient ice from Antarctica have found that ocean temperatures dropped by 2 to 2.5 degrees Celsius over the past 3 million years, while carbon dioxide and methane levels changed only modestly. The studies, led by researchers from Oregon State University and others, suggest factors beyond greenhouse gases drove much of Earth's long-term cooling. The findings come from ice cores at Allan Hills in East Antarctica.

Scientists debate causes of accelerating global warming

Senin, 16 Maret 2026 Dilaporkan oleh AI

Building on recent studies like Stefan Rahmstorf et al.'s analysis showing a doubling of Earth's warming rate to ~0.36°C per decade since 2014, scientists disagree on whether reductions in aerosol pollution or natural fluctuations are driving the speedup. Nearly all agree warming has accelerated, but views differ on causes, rate, and future trajectory—with implications for climate sensitivity and adaptation.

Warmer ocean drives Antarctic sea ice regime shift

New studies indicate that stronger winds and warming deep ocean water have triggered a sharp decline in Antarctic sea ice since 2016. Previously expanding, the ice reached a record high in 2014 before plummeting to record lows. Researchers link this shift to wind-driven upwelling of circumpolar deep water.

Scientists attribute Greenland platinum spike to volcanic activity

Jumat, 20 Maret 2026 Dilaporkan oleh AI

Researchers have identified volcanic eruptions, likely in Iceland, as the source of a mysterious platinum spike in Greenland ice cores from 12,800 years ago. This finding rules out a comet or asteroid impact and occurred decades after the onset of the Younger Dryas cooling period. The study provides new insights into abrupt climate shifts.
