Over the course of coming decades, though, trade wind speed is expected to decrease from
global warming, Thunell says, and the result will be less phytoplankton
production at the surface and less
oxygen utilization at depth, causing a concomitant increase in the ocean's
oxygen content.
«That assumption is so far entrenched in our thinking that
global climate models simply don't allow for methane
production in the presence of
oxygen.
But the evidence shows this can't be true; temperature changes before CO2 in every record of any duration for any time period; CO2 variability does not correlate with temperature at any point in the last 600 million years; atmospheric CO2 levels are currently at the lowest level in that period; in the 20th century most warming occurred before 1940 when human
production of CO2 was very small; human
production of CO2 increased the most after 1940 but
global temperatures declined to 1985; from 2000
global temperatures declined while CO2 levels increased; and any reduction in CO2 threatens plant life,
oxygen production, and therefore all life on the planet.
Marine microorganisms that drive many
global ocean processes (e.g.
oxygen production, primary productivity and biogeochemical cycling) are able to adapt to ocean acidification [49].
