Uma nova pesquisa mostra que o derretimento das geleiras na Groenlândia pode liberar grandes quantidades de metano aprisionado como hidratos sob o gelo. Cientistas alertam que esse processo, observado após a última era glacial, pode se repetir à medida que o clima aquece.

Pesquisadores liderados por Mads Huuse, da Universidade de Manchester, examinaram dados sísmicos de 2011 e 2013, juntamente com núcleos de sedimento da Baía de Melville, no noroeste da Groenlândia. Eles identificaram 50 marcas no fundo do mar com até 37 metros de profundidade, formadas quando a água do degelo arrastou hidratos de metano dos sedimentos durante o último máximo glacial, entre 29.000 e 19.000 anos atrás.

Study finds hidden channels speed Antarctic ice melt

A new study shows that channels beneath Antarctic ice shelves can trap warm ocean water and accelerate melting from below. Researchers focused on the Fimbulisen Ice Shelf in East Antarctica and found that this process may make even cold regions more vulnerable. The findings suggest current climate models could underestimate future sea level rise.

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.

Diving robots uncover cause of Antarctica's sudden sea ice decline

Scientists using deep-diving Argo floats have pinpointed the reason behind Antarctica's dramatic sea ice contraction starting in 2016. The decline stems from a violent release of pent-up heat from ocean depths, triggered by shifting winds and salinity changes. This discovery highlights the ocean's key role in sea ice variability.

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.
