As the ice fields of the Patagonian Andes shrink, the tectonic plates below simultaneously push upwards. The researchers found that heavy glaciers weigh down the floating sections of the mantle; when the ice melts, the ground below rises rapidly.
The ‘Blue Blob’, a mysterious sheet of freezing water in the North Atlantic Ocean, appears to have slowed the rate of melting of Icelandic glaciers by up to 50%. But experts warn that unhindered climate change could overcome this cooling effect by the 2050s.
Chimpanzees from the Rekambo community have been seen applying crushed insects to their wounds and those of other members of the troop, suggesting that they may benefit from the pharmacological properties.
