Collecting geophones! We had cracking weather last Friday and began active seismic work, using small amounts of explosives as our "source" of energy (seismic waves) to gather information about what lies beneath the ice on the

Our CEO and President have written a response to this climate science red herring. "We are all feeling the realities of climate change first-hand. Let’s focus on solving the problem – or at the very least mitigating against the worst ravages".

Still correct though that the vulnerability of this region has generally been under-appreciated and that it needs closer and continuing study.

Australia, US, UK, France, now China have a long cooperation within the ICECAP project that has been paying attention to this region. The reason we know the bedrock vulnerability is from ICECAP.

For an otherwise usually credible journalist, a simple question: How does being elected with established (“individual 1”) and credible pending cases of electoral abuse, coupled with a utter fabrication of lies about a policy ever turn into a mandate?

All the “glacial terminations” (ends of the ice ages) are fundamentally connected with the changes in the earth’s orbit. These affect the intensity of seasonal warmth. Then CO2 and it’s feedbacks get involved. Complex. Imperfectly understood.

Thanks for a much needed perspective! Collective action impacts the big critical sectors coherently. Encouraging individual lifestyles with diverse contributions and choices is positive and drives change without artificial virtue symbols.

It really is a fantastic experience even if you’ve had the privilege of being there. A very nice article about a great exhibit!

Given the ~70 Gt/yr you’re cranking into the ocean even now I’d expect a little of Totten is everywhere. (Of course, clarifying for the non-specialists, this is not net loss - you’re busy piling it on too)

Definitely, but also Antarctic Petrel I think on some occasions. Ever curious about our unexpected presence, checking out camp or traverse before moving along.

Even 550km inland at 2800m elevation I've seen visits like this...

One of the unspeakable privileges of deep field work in Antarctica: Hundreds of kilometres from any human outpost and standing where no human has trod. And then a petrel swings by!

See my retweet with comment - different circumstances require different approaches.

I agree. Creating false dichotomies isn’t helpful. The fact is that circumstances vary. Scientists where I work can’t catch an overnight train to a key meeting. Agree too there’s a cost both to developing careers and science that bad faith denier arguments could impose.
