This video [0] tries to answer the question of how we know what we know for a different species but I imagine the methods are similar.

As the parent says, the goal is to have NET 0 emissions. Certainly some emissions will still occur but they need to be small enough to be offset by CO2 removal. Because it is almost always much easier to prevent emissions rather than remove CO2, preventing 100% emission from cars and their production is likely to be best path to NET 0.

According to the EPA: "Hot water dissolves lead more quickly than cold water and is therefore more likely to contain greater amounts of lead. Never use water from the hot water tap for drinking, cooking, or making baby formula."

The applicability of this advice is probably quite variable.

Several kinds of semiconductor materials are used for high power or high frequency applications but only at much larger process nodes. For example Gallium Nitride, InP, SiGe.

New comment by e2e8 in "Earth is trapping twice as much heat as it did in 2005"

e2e8 — Mon, 28 Jun 2021 09:17:08 +0000

Abstract

Earth's Energy Imbalance (EEI) is a relatively small (presently ∼0.3%) difference between global mean solar radiation absorbed and thermal infrared radiation emitted to space. EEI is set by natural and anthropogenic climate forcings and the climate system's response to those forcings. It is also influenced by internal variations within the climate system. Most of EEI warms the ocean; the remainder heats the land, melts ice, and warms the atmosphere. We show that independent satellite and in situ observations each yield statistically indistinguishable decadal increases in EEI from mid-2005 to mid-2019 of 0.50±0.47 W m-2 decade-1 (5%-95% confidence interval). This trend is primarily due to an increase in absorbed solar radiation associated with decreased reflection by clouds and sea-ice and a decrease in outgoing longwave radiation (OLR) due to increases in trace gases and water vapor. These changes combined exceed a positive trend in OLR due to increasing global mean temperatures.

New comment by e2e8 in "Oakland bans the use of combustion engine-powered leaf blowers and trimmers"

e2e8 — Fri, 05 Mar 2021 19:03:19 +0000

From the above cited paper:

In 2011, approximately 26.7 million tons of pollutants were emitted by GLGE (VOC=461,800; CO=5,793,200; NOx=68,500, PM10=20,700; CO2=20,382,400), accounting for 24%−45% of all nonroad gasoline emissions. Gasoline-powered landscape maintenance equipment (GLME; leaf blowers/vacuums, and trimmers, edgers, brush cutters) accounted for 43% of VOCs and around 50% of fine PM. Two-stroke engines were responsible for the vast majority of fine PM from GLME.

There are at this point billions of cameras running continuously or within arms reach. Instead of speculating about silly eye witness reports, lets wait for the physical evidence to materialize. Look how many videos there are of the Chelyabinsk meteor.

This is precisely why I use f.lux[0] on every computer. As the blue light is reduced toward evening, the screen becomes much less bright. Works great for eye comfort and is maybe even beneficial for sleep.

My own view on this is that the only thing that is worth discussing here is the actual physical evidence that we have. Specifically, the 3 IR videos. Mick and others on youtube that I have seen give a very reasonable account of those videos. That is all the actual data we have. Everything else is just something somebody said and to me that is worth nothing. Trying to evaluate those accounts leads to very unproductive internet arguments. If somebody says there is other actual physical evidence, then lets see it and examine it. Until then the case is closed.

e2e8 — Mon, 05 Oct 2020 06:19:47 +0000

Yes, this is the only kind I buy but even better is High Pressure Processing. This pasteurizes the milk with pressure rather than heat preserving all the desirable properties of raw milk without any of the risks. There is a company in Australia (Made By Cow) selling this kind of milk but it does not seem to have spread to other countries yet.

Based on a quick search, that does not seem to be true. The title of the movie comes from the title of the book it is based on. The book's author has given some explanations for the origin of the title that do not involve Glasgow trains. [0] It seems the name for the subway comes from the movie. There also seems to be some dispute about the usage of that name for the Glasgow subway. [1]

No, you could simply write a program that you ran ahead of time that would simulate the correct screens in response to their inputs and make it look like the calculator was reset when in fact it was not.

The documentary is not actually 60000 hours long. There is well under an hour of footage for the carpenter so the whole thing is maybe a few hours and it loops those shots repeatedly. It is presented as if it is that long to emphasize the thesis of the documentary. It is kind of ironic that in a film which makes a big deal of the notion that there are no short cuts to mastery they took such a short cut in producing the supposedly very long documentary. I was disappointed to discover this because I was actually looking forward to at least a few hundred hours of nice footage of the carpenter working. They could easily have done that.
