Coal Formation Peat Compressed Sediments Heat Pressure Forces

Global CO2 trends follow northern hemisphere patterns because it contains more land mass and therefore more trees.

Global CO2 trends often mirror northern hemisphere patterns because this hemisphere contains a larger proportion of the planet's landmass and, consequently, more trees.
