Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone — a low-oxygen area that snuffs out … Continuer la lecture de Dead zones may threaten coral reefs worldwide

Eocene global warming events driven by ventilation of oceanic dissolved organic carbon

by Ph.F. Sexton et al., Nature, 2011 ‘Hyperthermals’ are intervals of rapid, pronounced global warming known from six episodes within the Palaeocene and Eocene epochs (~65–34 million years (Myr) ago)1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13. The most extreme hyperthermal was the ~170 thousand year (kyr) interval2 of 5–7 °C global warming3 during the Palaeocene–Eocene Thermal Maximum (PETM, 56 Myr ago). The PETM is widely attributed … Continuer la lecture de Eocene global warming events driven by ventilation of oceanic dissolved organic carbon
