“Past Climate Change helps us to understand how the earth has stayed habitable throughout the climate challenges of the past and how it may face the climate challenges of the future.”

Global climate stabilisation by chemical weathering during the Hirnantian glaciation
Lithium was created during the Big Bang at about 13.8 Ga. Lithium is concentrated in Earth’s upper continental crust and in 124 mineral species, the greatest mineralogical diversity being found in pegmatites. Lithium occurs naturally in two isotopes, 6Li and 7Li, which are readily fractionated, thus becoming sensitive to geological and environmental processes. Closed-basin brines (58%) and pegmatites plus related granites (26%) constitute the main sources of exploitable lithium worldwide. Life as we know it at the start of the 21stcentury would not be possible without lithium as it is used in a myriad of applications ranging from lithium-ion batteries to medicine.
Scientists have shown that mineral carbonation can permanently capture and store carbon quickly enough and safely enough to rise to the challenge of climate change. Source: Basalts Turn Carbon into Stone for Permanent Storage - Eos
