1. Oil & gas companies still expect the world to consume large quantities of oil & gas in 2050. That view would seem to put the oil giants in conflict with the IPCC.

"It's just an element, a tool to explore different trajectories on the basis of the knowledge we have today & to see what ... might encounter."
Both critics & modelers agree such nuance is often lost
BP projected BECCS would reduce emissions by 1.5GtCOโ/yr in 2050.
Equinor didn't even model BECCS because it said the technology's future was too uncertain.
The IPCC sees BECCS capturing 3-7GtCOโ/yr in 2050
The pathways the models produce aren't necessarily the only ones possible. Most of the time, they're just the cheapest.

What is cost-effective? We assume that this means discounting & optimising costs over the 100 years, assuming everything runs perfectly smoothly & everyone behaves, & we know everything (like costs).
The world is not this nice, unfortunately...
They could not model the cost effectiveness of this pathway. Is it cheaper or more expensive than a BECCS pathway? We don't know!

It is hard to trade-off supply-side & demand-side costs. This means we only estimate cost-effective on supply-side.

Is cost-effective, as defined in an IAM, the same as the real-world definition of cost-effective?
This is the question we need to address...

THREAD: 12 Things Everyone Should Know About IQ
1. IQ is one of the most heritable psychological traits โ that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE
2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less. https://t.co/UqtS1lpw3n
3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N โ 4 million)
(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)
4. IQ predicts many important real world outcomes.
For example, though far from perfect, IQ is the single-best predictor of job performance we have โ much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3
5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)

The first area to focus on is diversity. This has become a dogma in the tech world, and despite the fact that tech is one of the most meritocratic industries in the world, there are constant efforts to promote diversity at the expense of fairness, merit and competency. Examples:
USC's Interactive Media & Games Division cancels all-star panel that included top-tier game developers who were invited to share their experiences with students. Why? Because there were no women on the
ElectronConf is a conf which chooses presenters based on blind auditions; the identity, gender, and race of the speaker is not known to the selection team. The results of that merit-based approach was an all-male panel. So they cancelled the conference.
Apple's head of diversity (a black woman) got in trouble for promoting a vision of diversity that is at odds with contemporary progressive dogma. (She left the company shortly after this
Also in the name of diversity, there is unabashed discrimination against men (especially white men) in tech, in both hiring policies and in other arenas. One such example is this, a developer workshop that specifically excluded men: https://t.co/N0SkH4hR35
