"Any measurement, carbon dioxide, methane, nitrous oxide... We're losing all of the ice of the world... The oceans, the plankton, the corals, the fish, , oceanic dead zones and deoxygenation... and , the amount of soil, the fertility of the soil, the moisture of the soil, and permafrost is releasing tons of methane... unstoppable."
