Cooling the Oceans is a no-brainer, if it can be done. There were a few recent publications talking about melting from “below”.
Here a recent WWF post including a Video explainer clearly targeted at the wider public (rather than experts). https://www.arcticwwf.org/the-circle/stories/omg-greenlands-glaciers-are-melting-from-below/ From: 'Clive Elsworth' via NOAC Meetings <[email protected]> Sent: Thursday, June 1, 2023 3:10 PM To: [email protected]; [email protected] Subject: Clouds in the Arctic only provide cooling during a short period during the summer Hi Stephen – and cloud experts I found this paper educational, by Shupe et al, 2004: Cloud Radiative Forcing of the Arctic Surface: The Influence of Cloud Properties, Surface Albedo, and Solar Zenith Angle: https://journals.ametsoc.org/view/journals/clim/17/3/1520-0442_2004_017_0616_crfota_2.0.co_2.xml It says low level clouds in the Arctic only provide cooling during a short period during the summer. The rest of the year they warm the Arctic. So presumably, as increasingly warmer seas flow into the Arctic these clouds will get thicker (i.e. greater Liquid Water Path – LWP) because the air will be more humid, making each cloud droplet bigger. So, it seems that to cool the Arctic the oceans need to be cooled. Have I got that right?

It is a surprise to see this in Nature. Stephen >Nature - Overshoot Yes a surprise, especially as it’s so easy to avoid another glacial period.
