Kebakaran hutan Arktik lepaskan karbon yang tersimpan selama ribuan tahun

Kebakaran hutan yang melanda kawasan Arktik dan boreal memicu terbakarnya karbon purba di dalam tanah, melepaskan jauh lebih banyak karbon dioksida daripada yang diperkirakan oleh model iklim. Sebuah studi baru terhadap sampel inti tanah menunjukkan bahwa beberapa kebakaran membakar materi organik yang berusia hingga 5.000 tahun.

Meri Ruppel dari Institut Meteorologi Finlandia memimpin penelitian tersebut. Timnya mengumpulkan sampel inti tanah dari lokasi kebakaran dan menemukan bahwa vegetasi permukaan yang terbakar sering kali memicu bara yang lebih lambat di lapisan yang lebih dalam dan lebih tua. Proses ini melepaskan karbon dioksida dan karbon hitam yang menyerap sinar matahari dan mempercepat pencairan saat mendarat di atas es atau salju.

Study reveals underestimated carbon emissions from boreal wildfires

A new study from UC Berkeley indicates that climate models may significantly underestimate carbon emissions from wildfires in boreal forests due to overlooked peat soil burning. Researchers analyzed 2018 wildfires in Sweden and found that smoldering underground fires release ancient carbon stored for centuries. This discrepancy highlights potential gaps in global emission estimates, especially in vast regions like Siberia and Canada.

Arctic peatlands expand as warming creates feedback risks

Selasa, 24 Februari 2026 Dilaporkan oleh AI

A new study reveals that peatlands in the Arctic are growing due to rapid regional warming and increased precipitation, potentially storing more carbon but also heightening the risk of releases through fires. Researchers warn of a dangerous feedback loop as these carbon-rich ecosystems respond to climate changes. The findings highlight the dual role of these landscapes in global warming mitigation.

Ice core shows low CO2 in Pliocene warm period

Researchers have analysed a 3-million-year-old ice core from Allan Hills in Antarctica, measuring atmospheric CO2 at 250 parts per million and methane at 507 parts per billion during the late Pliocene. This epoch featured global temperatures about 1°C warmer than today and sea levels up to 25 metres higher. The levels are lower than previous indirect estimates.

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.
