Policy and technology

Not in my backyard:  wind turbines [link]

Can climate adaptation lead to increasing vulnerability? [link]

Beyond wickedness:  managing complex systems and climate change [link]

Assessing the hazard from aging dams in the US [link]

Is burning wood for power carbon neutral? Not a chance [link]

The perversion of precaution [link]

A movement grows to help farmers reduce pollution and turn a profit [link]

“The fear of natural disasters has caused more than 1.3 million people living in the #Mekong Delta to migrate to HCMC and elsewhere.” [link]

All politics is local, including climate politics [link]

India plans dam on Brahmaputra river against Chinese projects [link]

Could solar geoengineering be more effective than emissions cuts at offsetting Greenland surface mass balance loss? https://tc.copernicus.org/preprints/tc-2020-347/

Technology distruption: “Green” steel in Sweden [link]

Carbon unicorns and fossil futures.  Whose emissions reduction pathways is the IPCC performing? [link]

About science and scientists

Mark Steyn has filed a Motion for Summary Judgement in the Michael Mann libel suit. https://steynonline.com/documents/10973.pdf with memorandum https://steynonline.com/documents/10974.pdf

Conservatives are more anti-scientist than anti-science: Cons generally agree that science benefits society & these attitudes have been stable over the past decade. But increasingly, they do not trust the people running the scientific community: https://academic.oup.com/sf/article/99/1/305/5685787?login=true

New paper finds risks of natural disasters going down (1970-2019) for both people and property (even as financial risks increase with more wealth) https://sciencedirect.com/science/article/abs/pii/S0305750X20304174

The lab leak hypothesis [link]

Fight cancel culture on campus [link]

Alike minds think great [link]

The Dunning-Kruger Effect is probably not real [link]

Richard Dawkins: The insidious attacks on scientific truth [link]

New FIRE survey of campus speech policies: 88 percent of the 478 U.S. colleges surveyed have policies that restrict free speech. https://thefire.org/report-88-of-universities-restrict-expression-and-online-classes-are-especially-dangerous-for-student-speech/

A cautionary tale of the destructiveness of PR in science. Press conferences and media proclamations are poisonous bcs the scientists themselves start to believe their spur-of-the-moment ego-soothing extravagance. [link]

The threat to academic freedom . . . from academics [link]

Joan Didion: Learning not to mistake self-righteousness for morality [link]

A path less taken to the peak of the math world [link]

Ideological bias in academia is so bad that @glenngeher couldn’t even publish a study about ideological bias in academia. [link]

Roger Pielke Jr:  The unstoppable momentum of outdated science [link]
