Oil/Natural Gas Formation Anoxic Conditions Created Sediments Ocean

CO2 levels are fluctuating annually, steadily increasing, at historically high levels, and conform to northern hemisphere patterns.

CO2 levels are characterized by annual fluctuations, a steady long-term increase, reaching historically high levels, and conformity to northern hemisphere patterns.

Front Oil/natural gas formation
Back anoxic conditions created by sediments on ocean floor, burial and compaction heat the matter to form hydrocarbons, then oil and gas, forced to accumulate in porous rocks
