Science¶
Ancient Arctic carbon pouring into ocean but seabed captures most¶
Thawing Arctic permafrost releases ancient carbon into oceans, but sediment cores show most becomes buried rather than released as greenhouse gases.

Coastal cities sinking faster than ocean is rising¶
New research reveals densely populated coastal regions experience relative sea-level rise averaging 6mm annually, nearly three times global average, due to land subsidence.
