    Traditional physics based weather models also rely heavily on physical parameterization for sub grid scale processes (think clouds, microphysics of rain sleet snow, etc) so even th…

    ECMWF has an experimental AIFS direct observational prediction model (AIFS-DOP) that has become competitive with their physics based IFS model on certain metrics just in the past y…

    Heat domes are already killing off cattle and reducing crop yields, even in western countries? There was significant cattle die off in the US during 2022/2023. Europe just experien…

    Its a bit more complicated than that, you have a period during the spring called the spring persistence barrier that makes skillful prediction of a developing el nino difficult. Wh…

    Funding was proposed by Congress during the Biden administration but didn't get a lot of press at the time https://www.politico.com/news/2023/07/01/white-house-cautiou...

    Its regionally complicated because increased tree cover can lower albedo (reflectivity of radiation) which offsets the co2 removal benefits. Forrests can tip from co2 sinks to co2 …

    Being next to a nuclear power plant but attached to a regional grid is not that relevant in terms of total additive emissions from a data center build out. You have to look at the …

    The nuclear generating station is part of a larger system. Say you build enough data centers in your local area to use up all the station power so that 80% is no longer exported, w…

    It is much more than the Colossus sites, I would look at the capacity additions in the regional grids you are apart of and what is being funded to meet these increases in demand fr…

    The amount of nuclear generation is roughly fixed (minus the refurbishment of three mile) in that region. If you add additional large load to the grid and outbid other demand for t…

    But in PJM they are almost entirely being powered by natural gas and coal? Even if you contract out power from a nuclear plant some other plant on the grid is now enjoying a higher…

    One objective measure of satisfaction is if you are alive and healthy, hard to be satisfied otherwise.

    Emigration of Germans to the USA is only 10,00-15,000 people per year since 2000 and is trending down especially since 2016 to lowest levels ever. Emigration of US citizens to Germ…

    Why is the median considered "poor"? The true poor in Mississippi are way worse off than those in Germany. If you neglect everything it takes to live a good life like public capita…

    The water at these temperature / depths has a lot of dissolved salts and minerals so it's not (human / ag) usable. Modern designs are closed loop systems where production wells bri…

    Newberry Volcano is too good to be true in that there are few (outside of Yellowstone) equivalent sources of geothermal awesomeness at similar depths in the USA. Good for research …

    It does work technically I think it is still an open question if it can work economically. There are issues of commercially viable flow rates / thermal decline rates that are harde…

    The core breakthroughs were working with partners to develop PDC bits that enable high rates of penetration in drilling out these horizontal wells in high temp granitic rock and th…

    In traditional fault hosted (not magmatic) geothermal the convection of the water up the fault brings the thermal energy closer to the surface where drilling depths are economical.…

    Fervo uses engineered reservoirs in granitic basement rock so this is less of an issue. Hot rock in a working fluid can still dissolve silicates out of the granite and lead to scal…

    In geothermal there is still a lot of interest in efficiency and exploring different working fluids because binary systems now have efficiencies of 10-20%. That is why you see comp…
