Follow me concerning radical reductions of GHG emissions and consumption. Of particular interest are aviation emissions and growth in travel. I am an engineer.

For now I will mainly be active on twitter:

Good TV report showing how sea level rise is affecting the US coast. Even shows a familiar data curve from salt marshes (from the Kemp et al paper I was involved in).

I don't think this is getting the coverage it needs. Scottish government to require passivhaus standard for all new build homes. This is big. Really big. Growing out of lessons from the 70's oil crisis. Passivhaus buildings use very little energy to heat, or to cool. We've known how to do this for decades. It's gross negligence from all western governments that the same is not true of all new builds in the developed world.

@jgkoomey @jtemple this prompted me to learn more about the international legal situation wrt atmospheric pollution (Montreal, UNFCCC, and beyond). Governance is complex, but the unilateral private release of SRM chemicals is about as irresponsible as continued Govt funding of fossil fuel exploration & production #SRM #MontrealProtocol #UNFCCC #climatechange https://www.ohchr.org/sites/default/files/2022-06/Annex-SubmissionCIEL-ETC-HBF-TWN-Geoengineering-Opinion.pdf

And yes, this looks like a case of bad press release. Scientists should insist on being involved in media releases about their work, and if needed veto misleading hype.

There are misleading headlines claiming „Greenland melting 100x faster“. But the study only concerns melt rates at vertical ice cliffs in contact with sea water. It has nothing to do with overall ice loss from Greenland, mostly via surface melt & calving. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022GL100654

Engaging aviation workers and trade unions - Stay Grounded

Climate campaigners are coalescing around an agenda of no expansion of airports and the need for a long-term reduction of aviation. However, not all of these campaigns have incorporated worker perspectives to better understand the impact on jobs and changes to local and national economies. Jobs are one of the main industry arguments for airport […]

Two related studies by Bo Nordell (Lulea Uni of Tech) which aren't in the references may be of interest. His main area of research has been large scale underground thermal energy storage (UTES), but these studies consider the fate of heat production of both fossil fuels and nuclear plants:

Significant decrease in days with #Snow cover in #Germany of up to 65% at low elevations since 1961! In the topic of the day from @DeutscherWetterdienst I explain the #Statistics in more detail and why our selective mind paints the past even rosier (rather whiter) than it actually was.

Wetter und Klima - Deutscher Wetterdienst - Thema des Tages - Früher war mehr Schnee - oder doch nicht?

"Früher war mehr Schnee", sagte die Großmutter zu ihrem Enkel. Lässt sich das statistisch belegen oder handelt es sich nur um ein subjektives Empfinden?

Reblogging is organic user behavior and Twitter built the quote tweet feature because so many people were doing it manually already. It’s a huge burden on the user not to have this simple and important feature on a social platform imo (again just my personal opinion!)

Journalists will never stick around this app long term sadly unless it adds quote posting. We desperately need it to communicate effectively, build on each others ideas, and add crucial context to posts. These are things replies simply do not accomplish. Also quote posting or reblogging does not = harassment! Tumblr, for instance, has had the feature since the beginning. We need it here now too 🙏🏻
