With the current emission reduction targets set us on a pathway to 2.7-3.1 degrees Celsius, the report illustrates the urgent need for country leaders to step up their efforts to reach the targets set in the Paris climate agreement

MANILA, Philippines (Dec. 3, 2017) — The climate battle is an uphill trek. With our current commitments to reduce our carbon emissions, we are not on track to achieve the principal aim of the Paris climate agreement: keeping global temperature rise to well below 2 degrees Celsius, while pursuing 1.5 degrees Celsius.

Ubsunur Hollow Biosphere Reserve, on the border between Mongolia and Tyva, is one of the last remnants of the mammoth steppe, Earth’s most extensive biome during the Last Glacial Maximum. Last summer, scientists met to discuss changes in ocean circulation between this glacial maximum period and the present time and how these changes are related to changes in the climate and carbon cycling.

A new study of the late Pliocene era could help scientists predict future sea level rise

November 22, 2017 — When Earth’s atmosphere warms, the vast sheets of ice over Antarctica and Greenland melt. This melting, in addition to the thermal expansion of water, leads to rising sea levels. Although it’s clear that seas are rising at an increasing rate, Continue reading How Earth’s Orbit Affected Ice Sheets Millions of Years Ago
