Real science, real questions
Q21: What is the relationship between temperature and CO2 concentrations during glacial-interglacial cycles?
Q22: What is the difference in CO2 concentrations between maximums in interglacial periods (i.e. peaks in the
sites.gsu.edu/geog1112/lab-6…
2/"graph) and maximums in glacial periods (i.e. valleys in the graph)?
Q23: Why do atmospheric CO2 concentrations increase and decrease so much during glacial-interglacial cycles? 
Q24: Compared to the present-day global average temperature, how much lower was the global
3/"average temperature 21,000 years ago?
Q25: How much did CO2 concentrations increase from 21,000 years ago to 1500 A.D? 
Q26: Why have CO2 concentrations increased by at least another 100 ppm from 1500 A.D. to the present?"
4/Ice cores from the Greenland ice sheet show temps were warmer 115,000 years ago during the last interstitial than today (i.e. before modern man). So Earth can assimilate human-produced CO2 & greenhouse gases just fine. It's on us to gradually become
5/more efficient using renewable energy while gradually weaning ourselves off fossil fuels, w/out disrupting the oil & gas industry and the jobs of those workers. There's a lot of work to do in other areas that'll let oil & gas make a seamless transition.

Portrait of Kim Jong Un as a Young Leader
[a lengthy thread]
“Furthermore, Fujimoto stated that "if power is to be handed over then Jong-un is the best for it. He has superb physical gifts, is a big drinker and never admits defeat." Also, according to
en.wikipedia.org/wiki/Kim_Jong-…
2/"Fujimoto, Jong-un smokes Yves Saint Laurent cigarettes, loves Johnnie Walker whisky and has a Mercedes-Benz 600 luxury sedan. When Jong-un was 18, Fujimoto described an episode where Jong-un once questioned his lavish lifestyle and asked, "we are here, playing basketball, Image
3/"riding horses, riding jet skis, having fun together. But what of the lives of the average people?”
So at 18 Kim Jong Un is "a big drinker, never admits defeat, smokes Yves Saint Laurent cigarettes, loves Johnnie Walker whisky", basketball, the Chicago Bull & Michael Jordan, Image

No First Use DPRK’s textbook nuclear deterrence is purely defensive. John Bolton argues for a preemptive nuclear first strike on North Korea. So the US is the real threat to DPRK.
@Mister_G_2
Proactively countering North Korea’s advancing nuclear threat
atlanticcouncil.org/in-depth-resea…
2/I would argue that since the US broke the rules and nuclearized the KP in the first place (when NK was waiting on a ☮️ treaty), what’s good for the goose is good for the gander. If US armed ROK w/ nukes DPRK has the right to defend by nuclear deterrence.
3/There’s a reason DPRK calls John Bolton “human scum”. He forced their hand strategically & politically (domestic optics) to put the pedal to the metal on strengthening their nuclear deterrence. In case the US ever does a preemptive nuclear first strike.

2 top fuels
“Natural gas is the best fossil fuel in terms of energy output per unit CO2 emitted. Biomass is renewable b/C a new crop can be grown after each harvest, and biomass is a low carbon fuel.”
why is biomass a better alternative to natural gas apex
lisbdnet.com/why-is-biomass…
2/“How is biomass used as an energy source?
Biomass can be burned to create heat (direct), converted into electricity (direct), or processed into biofuel (indirect). Biomass can be burned by thermal conversion and used for energy. Thermal conversion involves heating the biomass
3/"feedstock in order to burn, dehydrate, or stabilize it.

Is biomass really green?
Biomass is considered renewable because the plant material used to create it can be regrown and the carbon dioxide produced in burning it is re-absorbed by plant life, so it is carbon neutral

This is the 21st century right? 90% of ROK homes use primitive heating??
““ONDOL”- Ancient heating system with modern application. In South Korea over 90% of the houses have radiant floor heating. It is called Ondol, [meaning] warm stone.” korea-heating.eu/_1ondol_eng.php
2/I get primitive Ondol heating in small towns, villages or on a homestead, but South Korea using Ondol heating for 90% of citizens homes is backwards!! Way too much wood 🪵 is burned. ROK should heat homes w/ natural gas. Unreal.
en.m.wikipedia.org/wiki/Ondol
3/Rethinking it: South Korea has good forest management w/ green goals. Wood fuels & biomass are renewable and forests are carbon sinks and tend towards carbon neutrality. Nevertheless the benefits and utility of natural gas heating shouldn't be ignored.

"This...overview of the energy economy in the European Union (EU) in 2019...provides trends for the main energy commodities for primary energy production, imports and exports, gross available energy and final energy consumption."
ec.europa.eu/eurostat/stati… #Eurostat
2/The chart shows the Renewables and biofuel curve is on an upward trajectory, which is what we want. Instead of trying to increase the slope of the curve (i.e. accelerate the increase), just maintaining this slope will get us to the right goal. As renewables & biofuels increase,
3/and market incentives + gov't subsidies make oil & gas less appealing, capitalism will work its magic and consumer trends should shift towards consuming sustainable renewable and biofuel sources of energy. Slow and steady wins the race. Gov't mandates and closing down pipelines

The more you strengthen economic ties among countries w/ different political or ideological systems, the more you decrease chances of a military conflict. Economic cooperation over common denominator resources makes ☮️time desirable and profitable.
People will set ideological differences aside when everyone is able to get in on a slice of the pie. Before the advent of modern ideology, humanity survived the Ice Age and lived in caves following the herds thru the seasons. We can cooperate when it comes to survival.
Long before modern gas pipelines we were engaged in a more primitive way of living:
