Continued thread

As this is Mastodon, let me pre-emptively point out that, yes, these scientists are aware that >90% of teaching Climate Neutrality is about emissions reductions, not removals.

The IPCC is also aware of this, as am I at the European Commission.

All these people already wrote reports on that, this one is about land sinks and technological removals.

EU Scientific Advisory Board on Climate Change comes out with new report on carbon removals.

They recommend, i.a.

“Separate targets, stronger innovation support and environmental safeguards…

Integrating permanent removals into the EU carbon market over time for a cost-effective deployment…

Reversing the EU’s land sink decline”

climate-advisory-board.europa.euNew report outlines recommendations to scale up carbon dioxide removals while addressing opportunities and risks

"OTEC is a form of electricity production that exploits the temperature difference between deep and shallow ocean waters, and can power DACCS on floating platforms at a price competitive with coal-generated electricity... We show that a safe and sustainable level of OTEC-generated electricity powering DACCS for 70 years could result in up to a 35% decrease in the relative global mean temperature warming compared to a business-as-usual emissions scenario."

NatureMitigating anthropogenic climate change with aqueous green energy - Scientific ReportsReaching net zero emissions and limiting global warming to 2 °C requires the widespread introduction of technology-based solutions to draw down existing atmospheric levels and future emissions of CO2. One such approach is direct air CO2 capture and storage (DACCS), a readily available, yet energy-intensive process. The combination of DACCS and ocean thermal energy conversion (OTEC) allows for independently powered carbon capture plants to inject concentrated carbon into deep marine sediments where storage is generally safe and permanent. OTEC is a form of electricity production that exploits the temperature difference between deep and shallow ocean waters, and can power DACCS on floating platforms at a price competitive with coal-generated electricity. Here we highlight the scale of the challenge facing society. We show that a safe and sustainable level of OTEC-generated electricity powering DACCS for 70 years could result in up to a 35% decrease in the relative global mean temperature warming compared to a business-as-usual emissions scenario.

Im neuen Jahr geht es direkt weiter mit der Vortragsreihe der #S4F Osnabrück. Diesen Mittwoch geht es um #CarbonCaptureAndStorage mit Schwerpunkt #DACCS. Vortragende - bin ich diesmal selbst.

Wie immer wird der Vortrag aufgezeichnet. Wenn Ihr die Diskussion auch mitgekommen möchtet, dann geht das nur im google-freien Livestream, der dann hier läuft:

Selbstredend beginne ich mit einem kurzen Update wo wir stehen bzgl. #Klimakrise
