Elizabeth Kolbert on John McPhee’s “Encounters with the Archdruid” The nominal subject was the Sierra Club leader David Brower, but McPhee allowed a mining expert named Charles Park to share the stage.

John McPhee’s “evenhandedness harks back to an era when reasonable people could disagree.“ Elizabeth Kolbert writes about McPhee’s piece “Encounters with the Archdruid,” a classic of environmental reporting.

OPINION: When Should Universities Take a Stand? I've heard from some colleagues in response to my opinion piece on Institutional Neutrality that universities should take a position when they—or their members—are under attack. I agree.

OPINION: Institutional Neutrality, Yes. Silence, No. | Jack Geary Murphy Institutional Neutrality, Yes. Silence, No. Should universities take official positions on contested social and political issues? Or should they remain


Should universities take official positions on contested social and political issues? Or should they remain neutral? And if they stay neutral, does that mean they should stay silent? - I have a proposal.

Big shout out to Pele for the perfectly timed demonstration of hot spot volcanism—right when my Intro to the Earth System students were researching it for their igneous rocks problem set! Love when real-world events align with the classroom. Seems like you got my memo!

Right, that’s an interesting question about “outsourcing emissions” in globalized marketplace. I suspect since transport + electricity production are the majority of US emissions, it’s not the main story, but I’m curious how that’s is attributed.

Since we can reduce emissions in the US and EU, the question is can China and India turn that trend around. . .

Now, the point of the plot is just a reminder that while the TOTAL global emissions has not declined, as you show, annual CO2 emissions has been DECLINING in the EU since the 1980s and in the US since about 2008. Total global emissions is what matters, of course, emissions reductions is happening.

(2) “cement carbonation” - cements and mortars have calcium hydroxide in them which reacts with CO2 to make caclium carbonate, CaCO3, sequestering the CO2 as rock. But yes, there is also significant CO2 release during cement production. However, so of that is in the past for current stock of cement

Ok, sure thing. First definitions: (1) “Bunkers” refers to bunker fuels, which are fuels used in international aviation and shipping. These emissions can’t be attributed ton any individual nation

This is interesting, but masks some progress being made in emission reduction in the US and EU. Far from sufficient, but it’s not the case that nothing has been done.
