Even At CO2 Levels of 3,000+ ppm, New Research Shows That Sea Life Is Safe From Ocean Acidification
Read here. As has been widely noted by the hysterical MSM, Hollywood bimbocelebrities and the IPCC's climate change alarmists have predicted that CO2 levels higher than the current 390 ppm level will bring great harm to all ocean life, especially to the early development of calcifying invertebrates. A new peer-reviewed study, by actual non-Hollywood scientists, reveals that the predicted larval death by acidification is the usual liberal/left, anti-science hysteria on steroids.
Martin et al. analyzed the effects of incredibly high CO2 levels (low ocean pH) on Mediterranean sea urchins. Other than a slower larval growth at ~3560 ppm, the sea urchins were unaffected by the ludicrously low pH levels imposed on the test subjects.
"The authors write that "ocean acidification is predicted to have significant effects on benthic calcifying invertebrates, in particular on their early developmental states," and they note that "echinoderm larvae could be particularly vulnerable to decreased pH, with major consequences for adult populations."...explored the effect of a gradient of decreasing pH from 8.1 to 7.0 -- corresponding to atmospheric CO2 concentrations of ~400 ppm to ~6630 ppm -- on the larvae of the sea urchin...The eleven researchers found that "Paracentrotus lividus appears to be extremely resistant to low pH, with no effect on fertilization success or larval survival.""
