It is (likely) showing the 0.1% percentile of measured wet-bulb temperatures. i.e. in a given year, we expect 0.1% of the wet-bulbs to exceed this temperature or approximately 8 to 9 hours in a year.

NOAA has also recently released a mapping tool [0] that allows you to dig down to county level (scroll down to county map) for various hazards.

Living with someone with depression can be taxing on your own well-being, especially without a support group. Being supportive, always saying the right thing, etc. You absolutely need to find time for yourself. In my case, exploring new adventures on my own, always with an open invitation, sparked hope & excitement in my partner.

Canadian teachers are kind-of, sort-of well-paid including pretty good benefits [0]. Their salaries and their union's power are a large source of political "discourse" in Ontario.

A dog encyclopedia? I have one called "Dogs" by Bruce Fogle [0] that classes dogs whether they are good with children, suitable for urban living, etc.

The Gulf Stream doesn't shut down. The AMOC shuts off or decreases in intensity. This is thought to have led to a number of interesting climate blips since coming out of the last ice-age. i.e. melt water from North American land sheets flows into North Atlantic, making it less dense, and less likely to sink. This leads to a lessening in the AMOC. The Gulf Stream would have still flowed but perhaps not as intense nor have been "pulled" as far northward. One such event was 8200 years ago [0].

You can get a slight hint as to what it would look like by looking to the pacific northwest, Canada, Alaska. The northern pacific ocean has a "Gulf Stream" called the Kuroshio. However, there is no appreciable meridional overturning in the north pacific. Thus north-west portion of north america is colder than Europe at the same latitude. Roughly.

There will always be a Gulf Stream as long as there are westerlies, a coastline, and Coriolis [0]

Not necessarily. The AMOC transports heat poleward in order to balance the net surplus of solar radiation in the tropics and net deficit radiational cooling at the poles. Lessening this pathway may mean other pathways may need to increase to compensate: like storms in the atmosphere.

As long as the winds blow and the Earth spins, we will have a Gulf Stream. What the paper is referring to is the three-dimensional circulation driven by salt and heat fluxes. Sinking cold water near places like Iceland and gradual upwelling of hot water in the tropics. Net result is transport of heat from tropics to poles and since it is water with a high heat capacity, a lot of heat! If this 3D flow is lessened, it means other things must adjust to compensate --- like midlatitude storms etc. The AMOC also "pulls" the Gulf Stream more northerly before it closes the loop and comes down the coast of western Europe. So UK, Ireland warmer than you'd expect given the latitude. Clear as mud?

Any global climate model worth its salt will have a comprehensive carbon cycle submodel, tracking the sources and sinks of carbon in all its forms, between ocean, soil, land, and atmosphere. Some models evolve the amount and type of plants e.g. C1 to project future biome distribution [0]

One such model is aptly named TRIFFID [1]

And particulate matter. The lawn maintenance workers come to neighbouring houses and just blow the stuff onto the street and towards the other houses. Then another crew comes in and blows it back. It eventually all ends up at my house. Clogging up my cpu fans...

Kind of a corollary: Place something fixable in your PhD thesis so the examiners can find something to write about. Something that doesn't make you look stupid but will make them feel like they'd done a thorough review and won't focus on your more subtle but perhaps more disastrous errors. Perhaps just a thing PhDs tell other PhDs to do but never actually do themselves.

Buildings take up a major proportion of the carbon and energy budget. Consider contributing to EnergyPlus[0]:

I checked your numbers against [0]. Road distance NY -> SF = 2900 miles [1]. Model S mileage is 290Wh/mi [2]. That is 840kW for Tesla against 657kW for a single transaction. This is all order-of-magnitude stuff but... wow.

Boreal forests have a complex interaction with the climate system. The masking impact of trees on the snow underneath means the albedo or reflectivity of a boreal forest during winter is quite low -> absorption of heat in contrast to a tundra where the snow is fully exposed -> reflection of heat. Bonan 2008 [0] is an excellent discussion of the land surface heat balance globally. A google search for the title should give you a few links to a readable PDF.

I've had to do a lot of videos of my talks this year for virtual conferences. This would be useful to eliminate all of those ums and ahs. My 20-minute presentation would likely get cut down to 15...

I'd be interested to know the impact of cutting out the ums and its impact on the pacing/cadence of a talk.

I have wide feet and I buy all my runners through the New Balance store. Never an issue.

I like it. You'd need (many) more than one. Pluto has an orbit of 248 years. Kind of like putting your wifi router on a train track on your property line and sharing with your neighbours.

I use a physical HP42S ~1989. I've lost count of the number of batteries replaced over the years. Doesn't have an excess of functionality beyond what I need and fits easily in the hand. Only piece of hardware that I would grieve.

Edit: Reminds me of about 10 years back when a box of HP calculators was found in a local warehouse. Somebody went around taking orders and high-tailed it down there.

> In climate science we do a lot of downscaling. We take temperature and precipitation readings from a coarse scale Global Climate Model grid and map them to a fine scale local grid. Let’s say the global grid is 50x25 and the local grid is 1000x500. For each grid cell in the local grid, we want to know to which grid cell in the global grid it corresponds.

Climate scientist here. Colour me a little confused. We have a GCM which is (typically) on a structured grid, i.e. with latitudes & longitudes on a pixel-like grid. Finding the GCM (coarse) grid cell for a given latitude/longitude of the downscaled (fine) grid is an integer operation, i.e. invert lat = lat0 + i x delta_lat and lon = lon0 + j x delta_lon. Must be missing something here. Even if there is a strange projection, you can map it such that the deltas are uniform.

The southern hemisphere has not seen the same amount of polar "amplification" as the northern (b/c more land in the northern hemisphere). But still an active topic of research [0]
