A few things that caught my eye these past 10 (!) weeks
Politics-free thread, please!
Climate science
Partitioning climate projection uncertainty with multiple large ensembles and CMIP5/6 [link]
How changing content of clouds could influence climate change [link]
Antarctic ice dynamics amplified by Northern Hemisphere sea-level forcing [link]
Status and outlook for the climate change scenario framework [link]
Forcing of western tropical Sought Atlantic sea surface temperate across three glacial-interglacial cycles [link]
Earth greening mitigates surface warming by enhancing the efficiency in heat and water transfer (i.e., aerodynamic resistance). https://advances.sciencemag.org/content/6/47/eabb1981…
A very strong stratospheric polar vortex and other record-breaking phenomena made the Northern Hemisphere winter of 2019–2020 one of extremes. [link]
Oreskes:Severe weather event attribution: Why values won’t go away [link]
Unraveling glacial hydroclimate in the Indo-Pacific warm pool [link]
Interannual variability in the North America carbon cycle [link]
Anthropogenic stresses on the worlds big rivers [link]
Geothermal heat persistently warms the ocean’s bottom ~2000 m by 0.3-0.5°C via seafloor vents. With horizontal circulation heat accumulates over time. The abyssal ocean was 6-10°C warmer 9k yrs ago and still much warmer 1k yrs ago. [link]
Combining modern and paleoceanographic perspectives on ocean heat uptake [link]
Coherent stream flow variability in Monsoon Asia over the past eight centuries links to oceanic drivers [link]
Moist heat stress extremes in India enhanced by irrigation [link]
How large does a large ensemble need to be? [link]
Enhanced warming constrained by past trends in equatorial Pacific sea surface temperature gradient [link]
Inherent uncertainty disguises attribution of reduced atmospheric CO2 growth to CO2 emission reduction [link]
Decadal and multi-decadal natural variability in European temperatures [link]
No net warming in Sweden over the last 210 years [link]
East Antartica has cooled substantially since 1986 [link]
Koutsoyiannis: Atmospheric temperature and CO2: hen-or-egg causality? [link]
Oligocene much warmer than previously thought; this is difficult to explain & has implications for ice sheet stability. [link]
Water on Mars: discovery of three buried lakes [link]
“This is why hurricanes are bigger and longer-lasting and more intense than before.” New study shows that ocean stratification is increasing. [link]
Michael Kelly: Warming is not the only threat [link]
Michael Kelly: Until we get a proper roadmap, Net Zero is a goal without a plan [link]
MIsconceptions of global catastrophe [link]
Approximate calculations of the net economic impact of global warming mitigation targets under heightened damage estimates. The cure is worse than the disease? [link]
Compact nuclear fusion reactor is very likely to work [link]
BTI: How to stop the wildfires [link]
Extreme weather and marriage among girls and women in Bangladesh [link]
America needs a modern electric grid [link]
Do we focus too much on IAMs & scenarios? Do alternative methods need a more prominent role? [link]
“The UN Secretary General António Guterres’s call for India to give up coal immediately and reduce emissions by 45% by 2030 is a call to de-industrialise the country and abandon the population to a permanent low-development trap” [link]
The invisible elephant in the room with a Green New Deal is the staggering quantity of stuff that needs to be mined in order to build all the green machines, and where that mining and processing happens. https://dailycaller.com/2020/10/27/green-new-deal-laws-of-physics/…
Michael Pollan: The sickness in our food supply [link]
Room-temperature superconductivity [link]
Pielke Jr: Global CO2 emissions are on the brink of a long plateau [link]
Re-imagining the Colorado River by exploring extreme events [link]
Plan for climate solutions takes Georgia-specific approach [link]
G20 countries projected to miss 1.5C targets by wide margin [link]
Maybe the narrative that dense cities are better for the environment may be off. Here’s new research from Australia. http://newgeography.com/content/006840-high-density-and-sustainability
About science and scientists
Perceptions of stereotypes applied to women who publicly communicate their STEM work [link]
Academic air travel has limited influence on professional success [link]
Science and politics really don’t mix [link]
Kerry Emanuel: The perils of computing too much and thinking too little [link]
Five ways to ensure that models serve society: a manifesto [link]
If you average your own best guess with your best guess from the perspective of someone you often disagree with, you’ll tend to be more accurate. Disagreement is good! https://researchgate.net/publication/337275911_Taking_a_disagreeing_perspective_improves_the_accuracy_of_people’s_quantitative_estimates…
Are climate scientists being too cautious when linking extreme weather to climate change? https://phys.org/news/2020-10-climate-scientists-cautious-linking-extreme.html…
