A few things that caught my eye this past week.
Re-evaluating the ocean conveyor belt [link]
More robust #climate projections of #Arctic sea ice only possible by improving physics in simulations e.g. accounting for melt ponds & the loss of drifting snow [link] …
Key Role of Internal Ocean Dynamics in Atlantic Multidecadal Variability During the Last Half Century [link]
NASA update: Snowfall accumulation in parts of Antarctica increased in the 20th century. The added precipitation has led to some mitigation of sea level rise. Overall, Antarctica still lost more ice than it gained. [link]

What is the most appropriate palaeo period for comparison? Under RCP8.5, we end up with a mid-Pliocene climate by 2030 and the Eocene by 2150. With RCP4.5, we stabilise in the Pliocene [link]
Role of stratosphere, tropics and oceans in skilful forecasts of extreme NH wintertime storms [link] …
Some parts of Tehran are falling by as much as 25 centimetres a year. [link]

Soil is the biggest terrestrial carbon sink, but land degradation is reducing its ability to mitigate climate change [link]
Global Carbon Budget 2018 just published [link]

Unintended consequences: “Oregon planning to increase CO2 emissions by taxing plastic bags and banning straws.” [link] …
Long, informative read: problems with California’s cap-and-trade system [link]
Jonah Goldberg: Climate change frenzy clouds our judgment [link]
Protecting climate by protecting nature [link]
On the present improbability and future necessity of carbon pricing [link] …
Explaining differential vulnerability to climate change: A social science review [link]
Ocasio-Cortez’s Green New Deal [link]
‘Climate campaigners must now ask themselves which they prefer, renewables or the stable and long-term reduction of greenhouse gas emissions, for it is increasingly clear that they cannot have both. ‘ [link]
Climate policy backlash: “Activists and delegates in Poland begin to realize that a comprehensive transitioning over to green energies is not going to happen any time soon because their proposals are unmistakably generating anger.” [link] …
Lucas Bergkamp: As often in climate policy matters, the US is right: states should note, but not endorse the IPCC’s findings. A thorough debate on the limits of climate science is required before any IPCC findings are used to develop policy. Climate science on 1.5C erased at UN talks as US and Saudis step in [link]
Liebrich: Two business cycles to prepare for a low-carbon world [link]
The story behind the PG&E transmission tower that failed minutes before #CampFire roared to life. [link].

Heterodox Academy: A teachable moment at Sarah Lawrence College (of relevance to the Cliff Mass imbroglio) [link]
How can universities can better support public engagement activities, especially for geoscientists. [link]
This is a statement signed by 363 censorship advocates at Williams College. A perfect encapsulation of the fundamentalism sweeping America’s elite colleges. A collective student response to the “Chicago Statement” (also of relevance to the Cliff Mass imbroglio) [link]
Heterodox academy: Using open letters to shame and silence scholars undermines open inquiry and constructive disagreement. [link]…
“Are Academics Cowards? The Grip of Grievance Studies and the Sunk Costs of Academic Pursuit” [link]
A far cry from its mission, academia today resembles “a priesthood or a guild,” or even a “cult“, with peer review serving an essential administrative need in a system of promotion, tenure, funding, & accolades designed to maintain the established order. Academia’s case of Stockholm Syndrome [link]
