    -200F in the ice age WAS the warm spot. The polar caps were closer to -500F. The whole planet was an ice planet. It’s not like Florida was -200F, but Ohio was 73F.

      -500F is about 40 degrees F colder than absolute zero. It has never been that cold anywhere in the universe. -200F is certainly more “actually possible in our current understanding of physics”, but it’s over 100 degrees colder than the current Martian temperature and thus also not a temperature it’s ever been on Earth, even at the heart of the coldest Ice Age directly on the poles. While Earth’s average temperature has certainly fluctuated, the temperatures you’re talking about are so cold that all life on Earth would have gone extinct.

      So true. And before that don’t forget that Earth didn’t even exist, because it was just a clump of dust.

        No…it was extremely hot before the ice age. Do you seriously think the dinosaurs were just hanging out in 70 degree weather?

        Look at insects, as oxygen levels decreased they became smaller. Even alligators used to be like 150 feet…now they’re closer to 18-30 feet depending on type.

        The living creatures of that era were all bigger. It was more humid. There was more oxygen in the air. And then astroids hit, and basically were world ending events. Happened twice, hundreds of millions of years apart.

        And you think that YOU can kill a planet? No. This planet decides if it ALLOWS you to live. And humans are awful pests. Honestly surprised the 2 nukes in WWII didn’t trigger a 3rd ice age.

        But until the 3rd ice age, it’s just always going to get hotter. Humans or not.

          Why are you surprised? How do you think the nukes would have triggered a ice age?

            Same way the astroids did. Big boom, big ripple effect around the globe, and the force pushes the earth slightly out of orbit.

            Apperently nukes aren’t powerful enought to do what astroids did. I thought they would.

              Just checked from wikipedia, the yucatan impact was “The kinetic energy of the impact was estimated at 72 teratonnes of TNT (300 ZJ).” The Little Boy dropped on hiroshima was 15 kilotons of TNT. To say theres a vast difference is a understatement of the century.

              You either have wrong understanding or no understanding of physics.
