"Natural CO2 removal is increasingly being claimed as anthropogenic climate mitigation. This misrepresentation is already prevalent for forests and coastal ecosystems; there is now the risk of the error reoccurring for open-ocean CO2 uptake via the biological carbon pump."\

US-Israeli #geoengineering startup seeking US govt contracts to cool the planet has quietly begun lobbying on Capitol Hill

Stardust Solutions didn't disclose its lobbying "due to a clerical error"

E&E News: Geoengineering startup has been secretly lobbying Congress for months
Stardust Solutions hired Holland & Knight, but the lobbying giant says it "inadvertently" failed to publicly disclose its work for the startup, as required by law.

In an op-ed for TR, @davidkeith.bsky.social & @danvisioni.bsky.social voice deep concerns about Stardust & other for-profits racing into solar geoengineering — and asserting claims that, they argue, the science doesn't support.
Why the for-profit race into solar geoengineering is bad for science and public trust
Two scientists argue that the growing commercial efforts to counter climate change by reflecting away sunlight will thwart responsible research in the field.

Elon Musk has proposed using satellites to regulate the amount of sunlight reaching Earth, reviving debate over solar radiation management (SRM) — a controversial form of geoengineering aimed at slowing global warming.

In @technologyreview.com, @davidkeith.bsky.social and I explain why, especially if you think solar geoengineering is worth exploring, you should be skeptical of for-profit attempts. We bounced around thoughts for a while, but it got more urgent obviously.

Slow reductions=LESS CDR
I often see the argument that the more emissions remain the more CDR is needed. Example below
But it's the opposite! If a lot of emissions remain it means there wasn't enough political will & capital to address them. That will & capital won't magically appear for CDR instead
