    For a hardscrabble homesteader living in the cold mountains of New Hampshire, the balmy islands of the Caribbean may seem like a land flowing with milk and honey. But few of the greatest civilizations of the world were established in the tropics. Indeed, twice as many Puerto Ricans live in the continental US as live in Puerto Rico itself. With such an exodus north I'll bet you should be able buy a plot of land in PR that you could call home. :)
    Not everyone is as myopic as you.

    Will India get too hot to work? | McKinsey Global Institute

    ....We find that India could become one of the first places in the world to experience heat waves that cross the survivability limit for a healthy human being resting in the shade, and this could occur as early as next decade. Moreover, rising heat and humidity levels will impact labor productivity and economic growth in an economy that relies substantially on outdoor work....

    According to the scientific literature, 35 degrees wet-bulb temperature is commonly regarded as the heat-stress limit for human survival. At 35°C wet-bulb a healthy human being can survive, resting in the shade, for approximately five hours.

    While wet-bulb temperatures during the worst heat waves in India today rarely, if ever, exceed 32 degrees, the climatological analysis conducted for this case study indicates that temperatures during the most severe heat waves in the hottest parts of India could begin to breach 34 degrees wet-bulb by 2030. Such high temperatures have been recorded only a couple of times on Earth, including a 34.6-degree wet-bulb measurement on the coast of the Persian Gulf in July of 2015, and a later 35.4-degree wet-bulb measurement in the same region. Exposure to 34-degree wet-bulb temperatures will increase mortality risk for the sick and elderly, but more importantly, due to the amplifying urban heat-island effect which can raise temperatures in urban areas, for example, due to the presence of concrete buildings and limited green spaces, urban or peri-urban centers exposed to these temperatures may cross the 35-degree survivability threshold for healthy adults. By 2050, portions of northern India could begin to experience heat waves that cross the 35-degree wet-bulb survivability with a probability of occurrence at least once in the decade centered on 2050 approaching 80 percent (Exhibit 1). As heat and humidity increase, this could also affect labor productivity in outdoor work. This phenomenon occurs not only due to the need to take breaks to avoid dangerous core temperature rise, but also because the body will fatigue to reduce the amount of work (and therefore heat) that it is able to produce....

    More of Irish ancestry live in the United States than live in Ireland. You could say the same of many cultures and not all from the tropics. It wasn't climate that drew them here. It was freedom. When that is lost they'll stay home.

    I would say that people migrate because of increased opportunity, which might include freedom, but usually includes increased economic opportunity. In the case of Puerto Ricans, since they already are US citizens I don't think they are moving to the continental US because of "freedom." But I'm sure those that move north miss their free tropical avocados and mangoes, and, of course, those free "beautiful, soft towels. Very good towels."

    And the ones moving here from Canada and Scandinavia miss the wolves and bears.
    Sheesh!

    More false claims. The problem, as you claim it exists, is caused by overpopulation. More of the same garbage.

    We should forget about the Aztecs, Incas, Egiptians, Indians, Babilonians, Greeks and the rest of the tropical and sub-tropical ignoramuses. What a load of nonsense.

    Not only is it nonsense, it is balderdash and jabberwocky, which rhymes with hockey, not played on ice, of the equine variety.

    If we consider the two tropics as the rough demarcation between the Temperate latitudes and the Tropical latitudes, then most of the civilizations you've mentioned are partly or wholly in the Temperate zone.

    Aztecs: bisected by the Tropic of Cancer, but their capital, now Mexico City, at an elevation of 7400', has a temperate climate.

    Incas: within the Tropics, but because of their even higher altitude, a temperate climate. Cuzco - 11,000'; Lima - 7,400' Manchu Picchu - 7,900'.

    Egiptians Egyptians: Only the extreme south of current Egypt is south of the Tropic of Cancer.

    India: bisected by the Tropic of Cancer. The Indus valley, seat of the earliest Indian civilization, is north of the Tropic of Cancer.

    Babilonians Babylonia (as well as Persia and Assyria): solidly in the Temperate latitudes

    Greece: solidly in the Temperate latitudes.

    China: majority in the Temperate latitudes.

    All of Europe: solidly in the Temperate latitudes.

    The Islamic world at its pinnacle: mostly in the Temperate latitudes.

    Japan and Korea: solidly in the Temperate latitudes.

    But hey, bring on Global Warming...

    Climate change may make autumn leaves fall early and store less carbon
    • It's been thought that a fall in temperatures and diminished day length were the main factors that cause trees to lose their leaves
    • Researchers have identified a third factor -- a "self-constraining" productivity
    • Elevated carbon dioxide levels also causes trees to lose their leaves earlier, as well as store less carbon
    • By the end of the century leaves might fall off two to three weeks earlier
    • "We cannot just put more and more CO2 in the atmosphere and (expect) trees will just do so much more -- there are limits"
    The study was published in Science

    The King of nonsense attacks again. You keep on posting links that show your claim is a lie. Perhaps reading the article before posting would be less embarassing.

    "London ‘set for first snow of winter on Friday"
    Some people don't know the difference between Weather and Climate

    Weather
    We may have just seen the world's highest recorded temperature ever.
    Death Valley’s forbidding landscape registered a preliminary high temperature of 129.9F on 16 August, 2020.
    According to weather records researcher Maximiliano Herrera, the previous global record high for August is 127.9F (53.3C), recorded in Mitribah, Kuwait, in 2011.
    The Arctic experienced its first 100F day on record on 17 June 2020 when the Siberian town of Verkhoyansk hit 100.4F (38C). July 2020 was the hottest single month in more than a century of recordkeeping at such far-flung US locations as Phoenix; Miami; and Portland, Maine. If Sunday’s high at Death Valley is confirmed, it will be the planet’s highest temperature in almost a century and its third-highest on record, according to the World Meteorological Organization (WMO)

    Australia breaks spring temperature records, notches hottest ever November

    Australia has experienced its hottest spring on record, based on minimum and mean temperatures ...The Bureau of Meteorology also confirmed it was Australia's hottest November on record for maximum, minimum and mean temperatures.

    Earth Had Its Second Warmest Year in Recorded History in 2019
    just 0.04°C behind 2016, said NOAA and NASA on January 15. Global ocean temperatures and global land temperatures were both the second warmest on record. Global satellite-measured temperatures in 2019 for the lowest 8 km of the atmosphere were the third warmest or second warmest in the 42-year record, according to the University of Alabama Huntsville (UAH) and RSS, respectively.

    Exactly.
    It's going to be a cold winter/hot summer.
