Over 40% of global shipping by volume exists to move fossil fuels from one place to another.

A huge share of the world's maritime infrastructure has been built around a system that is going to change dramatically as renewable energy and electrification displace fossil fuels.

My husbands cousin worked as a teacher in Arizona and then at GAP on the weekend to get by. She switched careers because it was not sustainable. What a crazy country where they don’t value teachers. An important job teaching and inspiring our next generation.

Opinion | To Save Life on Earth, Bring Back Taxonomy (Published 2024)

Quote: "We need to be able to interpret genetic data in a way that humans can understand and use. That's taxonomy's job. AndΒ if we want to save what's left of the vast diversity of life on Earth, we'll have to reinvest in this science."

UVs from last week’s sample! Harpacticoida, Cirripedia nauplius (with Asterionellopsis glacialis next to it), Pseudocalanus (with Trieres mobiliensis/regia), not sure - Harpacticoida or Cyclopoida (what do you think?).

Economists love to point to insurance as the market-based solution for adaptation - allow premiums to reflect risk and adaptation will follow.

In the real world there are limits to the effectiveness of this approach.

My kid (grade 11.5, age 16) wants to study climate science, but would like more info on careers/jobs broadly in that field so she has a better idea of what she might like to do. If you studied climate science or similar, what do you do now? #science #womeninscience #womeninstem #climatescience

Rare Earth is back on air & today's programme was all about the OCEAN 🌊. What does the future of ocean exploration look like, and why does it matter? And we met a seal (name: "Seal-ia", see pic) modelling the latest in both ocean science & teacakes. Listen online here:

Group work and learning to work with others is an essential skill. Yes it’s hard to assess, but we shouldn’t stop doing it. I do think that we need to actually teach students how to do it better, rather than just expecting them to figure it out.

Deeper ocean ecosystems are unique – and uniquely vulnerable without better protection

A new study challenges a common assumption that deeper marine ecosystems act as refuges which could reseed damaged shallower reef systems.

The mining companies should be paying. But someone should clear up the land. Interesting documentary about this thst I watched recently. The waste slag heaps are large and the dust from them is influencing a large area. #asbestos #aus

The hard road back from overshoot - Nature Climate Change As global temperatures move beyond 1.5 °C, overshoot now defines the landscape ahead, sharpening legal claims, exposing economic risks and revealing how far politics still trail the pace of change.

The idea that we can β€œovershoot now, fix later” is simplistic.

Overshoot relies on massive CDR, but temporary warming can trigger tipping points and long-lived changes: ice sheet loss, permafrost thaw, ecosystem shifts.

Cooling later doesn’t guarantee reversal.

Australia’s most costly anti-climate policy hits taxpayers for $30m a day as calls mount to wind back fuel tax credits | Adam Morton The government will hand over $10.8bn this financial year under the scheme that makes it cheaper for miners and other industries to use diesel and petrol

Excellent piece in @us.theguardian.com by Adam Morton on massive fossil fuel subsidies in Australia to diesel.

β€œThanks to fuel tax credits, big companies are allowed to pay significantly less to burn dirty fuels than households”

We need a global assessment of avoidable climate-change risks To understand the urgency of emissions reductions, policymakers and citizens need a full analysis of what is at stake.

Major threats to our well being from climate change can be avoided, or hugely reduced, by rapid action.

Our Nature comment calls for a global risk assessment, effectively communicated to governments, the media and the public, to make clear what is at stake.

Anyone else dress on theme when they are teaching? I regularly wear this pair of shorts for my marine classes in summer. Combined with my PS Sonne t-shirt @sgn.one.
Nice to see I wasn’t the only one on theme today with Carissa Klein @uq-cbcs.bsky.social also dressed in a marine pattern dress.
