We are definitely going to be on the wrong side of history with this.
We are a country that said NO to Apartheid era South Africa.
We said NO to nukes.
But condemnation of the genocide in Gaza? That's just too much for our coalition govt.
Shame on them.

New Zealand prevaricates on whether to recognise Palestine as a state, or not.

This morning's #SolarEclipse as seen from up on Muaūpoko Otago Peninsula, Dunedin NZ.
The cloud prevented the full set of images & at regular intervals, but this is kinda fun.

NZ has now paid 120% of the full cost of 2 next generation, hybrid ferries for *checks notes* nothing at all. Those ferries were on track for 2025 & 2026 delivery.
Extra points: our only rail enabled ferry is being retired on Monday & maintenance costs have doubled

Finally some precise numbers for the Blatten deposit! 👇

I also derived a new elevation model from the aerial images, allowing me to visualize the elevation change in the affected areas.
The rocks and debris in the valley are locally up to 32m thick and I estimate the total displaced volume is about 11 million cubic meters. #Blatten

Ta teden smo seizmologi ARSO obiskali paleoseizmološki razkop na 80 km dolgem Raškem prelomu pri Kobdilju. Strokovno vodenje je izvedla dr. Petra Jamšek Rupnik iz GeoZS.
ARSO in GeoZS že vrsto let sodelujeta pri raziskavah aktivnih prelomov v Sloveniji.

The village of Blatten in Switzerland is partly buried by the collapse of a glacier which melted because our greenhouse gas emissions warmed the climate.
Another reminder that choosing to not invest enough today to reduce emissions means far greater costs for society in the long term.

NEVER try to drive through flood waters - most deaths from floods are vehicle related.
You’re also risking others lives and property 😞
Don’t walk, swim or play in flood waters - assume they are contaminated (human and/or animal sewerage, chemicals) or electrically charged.
Stay safe ❤️

Very sad to see the damage from the earthquake in Myanmar. My thoughts are with all affected by this disaster.
Understanding where and how much the fault slipped can help with damage assessments, so we've made some preliminary estimates from S2 (data: doi.org/10.5281/zeno...)

Heavy rain and blustery northerly winds are on the way!
The largest accumulations are forecast for the northwest of the South Island where 350-450mm of rain is forecast. This area could still be upgraded to a Red Warning.
