Growth response of <i>Emiliania huxleyi</i> to ocean alkalinity enhancement by G. Faucher, M. Haunost, A. J. Paul, A. U. C. Tietz, U. Riebesell

“…<p>The urgent necessity of reducing greenhouse gas emissions is coupled with a pressing need for widespread implementation of carbon dioxide removal (CDR) techniques to limit the increase in mean global temperature to levels below 2 °C compared to pre-industrial times. One proposed CDR method, ocean alkalinity enhancement (OAE), mimics natural rock weathering processes by introducing suitable minerals into the ocean, thereby increasing ocean alkalinity and promoting CO<span class="inline-formula">₂</span> chemical absorption. …”
