Climate Hustle

What will Earth look like in 2100?

Posted on 11 April 2019 by Guest Author

Climate Adam asks - how will climate change transform the world over the next 81 years? Will we rise to the challenge, or be overwhelmed by global warming by the year 2100?

  1. Imagine we would have evolved just a million years ago , do you think climate would have changed ? To what it is now ? Climate has been changing, is changing , and will always be changing untill our sun becomes a red star. We can't even predict the weather correctly for the next month . And you are talking about predicting the weather in 2100 ? The best way to go is nuclear power, solar and wind is a strain on the environment . Nuclear thorium power , that is.  I am far more worried about platstics everywhere in the food chain.

  2. Okay.
    This year the Arctic is expected to become ice free.
    When that happens the polar air will shift to Greenland where there still is ice. This will dramtically change the jet streams in the northern hemisphere and we can expect to see even more wild weather extremes.
    But that is not the biggest threat.
    Warmer air will move into the Arctic region which just so happens to be surrounded by permafrost. There is enough greenhouse gases in the permafrost to triple what we currently have in our atmosphere. It is over 7 times more than what we have emitted with the burning of fossil fuels in the last 300 years.
    In the seabed below the Arctic ocean there are vast reserves of methane hydrates that can destabilize from the water warming up. Just 1% of that being released will cause a global extinction.
    The President of Finland has already stated that if we lose the Arctic, we lose the world.
    When the Arctic loses all of it's ice, it will be like turning off the air conditioner in the Northern Hemisphere during the hottest time of the year.
    Temperatures will very quickly climb by as much as 18°C in just a decade.
    We will see a 4-5°C rise in just 3 years. A 3°C rise is probably enough to kill off most humans.
    It's not the temperature rise that will kill us but the speed in which it happens.
    Whereas humans have proven to be versatile with temperature change, the species that we depend on for food and the air we breathe are not so resilient to temperature changes.
    Even if we could somehow survive the extreme heatwave events during the summer months, we would still need food, clean water and an atmosphere with at least 19% oxygen content.
    Sorry folks but the oxygen content is also falling. That is to be expected when we chop down the trees that provide the oxygen. Wildfires will destroy the rest as well as convert some of the oxygen to CO2.
    Can the world really change in 81 years?
    Just in the last 40 years there has been a loss of 60% of the world's wildlife. It's not going to take another 40 years for the rest to die off.
    81 years is more than enough time for the world to change.

    That's not what the science tells us to expect.  Pretty much most of what you wrote after that is nonsense.  This is not the venue for you, if you're going to engage in speculation and fearmongering.

    Rhetoric and sloganeering snipped.
