Imagine that Greta Thunberg toils her life away for the next 50 years trying to get her fellow earthlings to take action, but they never do, civilization is rather in shambles by then, but we’re still pumpin’ greenhouse gases in to the atmosphere.Hmmm, fifty years, still business a usual, running all those engines? That doesn't really compute with the rate of changes we are seeing throughout this biosphere we depend on for everything. Here's just one example most try to ignore, but you can bet it will have hideous cascading consequence and it is heading our way sure as the sunrise and a morning shit. -
... Between 1850 and 2100, under the most conservative IPCC scenario for the trajectory of greenhouse gas concentrations, the decline in global-mean surface pH among models ranges from 0.12 to 0.14, a 36% increase in acidity;under the worst scenario, it ranges from 0.41 to 0.43, a 165% increase in acidity.
But pH is not the only concern.
Enhanced ocean CO2 uptake alters the marine carbonate system, which controls seawater acidity. As CO2 dissolves in seawater it forms carbonic acid (H2CO3), a weak acid that dissociates into bicarbonate (HCO3-) and hydrogen ions (H+). Increased H+ means increased acidity (lower pH).
The rate of the ocean’s acidification is slowed by the presence of CO32-, which binds up most of the newly formed H+, forming bicarbonate.
But that buffering reaction consumes CO32-, reducing the chemical capacity of the near-surface ocean to take up more CO2. Currently, that capacity is only 70% of what it was at the beginning of the industrial era, it may well be reduced to only 20% by the end of the century. …

And since being a bummer isn’t my only goal in life, I’ll not even mention the growing anoxic zones, oops, well no details, okay.
Why is this man still smiling? Because I have my life and today and have but one death to experience. Not to mention a sweetie waiting for me to come to bed.
