New piece from @veronikameduna.bsky.social on the latest disaster-in-the-making happening here in #NZ - a govt decision to defund social sciences, humanities, and other blue-sky research.

For Science Magazine (@science.org), I covered a wild mission to land a crack team of paleoclimate scientists by helicopter on a stormy, icy ridge near Thwaites Glacier to drill ice cores that could help us better understand the "doomsday" glacier's uncertain future. ❄️

May 2025 – join us in Ottawa for one of the many sessions at the GAC-MAC-IAH annual meeting. A joint meeting of three of Canada's main geoscience societies. Harmonized data is critical to overcoming differences that block the way to action in trans-jurisdictional regions - Looking for Perspectives!

The search for a site to store toxic waste has ended just north of Lake Superior near Ignace, Ontario. With the town and local First Nation’s support, it now moves ahead to various stages of review.

In Canada similar challenges exist - "Great Lakes Now posed the question “who’s in charge..."" can the new Canada Water agency address this challenge in Canada? Time will tell - It is a tall order – Do stakeholders have unrealistic expectations – hopes.

What overlies deeper basin pore space – groundwater–used for potable water. Coverage by "Great Lakes Now" It is easy to forget groundwater - in Michigan "44% of people secure their water from groundwater" in Ontario municipalities Waterloo, Cambridge, Guelph..

CO2 sequestration - from Great Lakes Now. Perhaps lessons highlighting challenges in pumping CO2 into the ground. Conceptually great – individual settings provide challenges. As southern Ontario hopes to exploit the Cambrian, are there lessons from Illinois? www.greatlakesnow.org/2024/10/the-...

Do you teach sedimentology? It is for you!
The @sedimentology.bsky.social, in collaboration with North Sea Core CIC, is sponsoring the distribution of core samples from various depositional environments to academic institutions

How do carbon taxes affect food prices? In our latest paper, @dr_jen_winter and I analyze both direct and indirect impacts across the entire food supply chain: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5024885

It's the most detailed exploration of CTaxes and food yet! 🤓 #cdnecon #cdnpoli

And while we're at it. Did you know that during our era of major climate investment in Canada we actually reduced the quality of our climate observing system in many parts of the north? 84bbf97c-1ba3-4840-8e5a-93b4adf7881f.usrfiles.com/ugd/84bbf9_6...

New paper alert! While
simple climate projections expect northern forests to become more productive with warming and take up more carbon, we show why this may not happen. Reminder that permafrost is the backbone of the Arctic. www.pnas.org/doi/10.1073/...

The list of conf. sessions is now available for Ottawa2025 annual meeting of GAC/MAC/IAH-CNC. Currently in a PDF file, but download and get an early feel for this multi-society meeting, Canada's premier geoscience meeting.

DYK that subsea permafrost exists?
That it can be found as south as 56°N?
and that it is maintained frozen by cold ocean currents?
-> Look at this paper from Normandeau et al. fresh out of the press! rdcu.be/dP7Li
