Tracking toward mass extinction
Where “Two plus two equals five if the party says so” (George Orwell)
and when drilling methane wells reduces global warming
Note the future estimates of CO₂ levels.

The rise in CO₂ in the atmosphere and oceans and the rise in ocean acidity (decline in pH).

According to the IPCC, as stated by the late Prof Will Steffen, Australia’s foremost climate scientist, if the exponential rise in greenhouse gas emissions continues we will already have crossed the upper limit that gives us a two-thirds chance of limiting warming to <2.0°C. Other scientists estimate that we have already missed the boat.
