Earth Might Freeze Due to Extreme Heat
Scientists have found that if Earth gets too hot, it might actually freeze instead of burning up.
This happens because too much heat and carbon dioxide in the air make it rain more, which washes rocks and pulls the CO2 into the ocean.
Tiny plankton in the sea eat the CO2 and then die, taking the CO2 to the seafloor.
This cools down the planet.
But if it gets too hot, the ocean gets too many nutrients, and the plankton grow too much, absorbing too much CO2 quickly.
This can make the Earth cool down very fast, leading to an Ice Age.
However, this will take a very long time and won't affect humans anytime soon.
Scientists warn that extreme heat could lead Earth into an Ice Age due to a natural thermostat failure.
Rising CO2 levels cause increased rainfall, eroding rocks and pulling CO2 into the ocean.
Plankton absorb CO2 and sink to the seafloor, depleting CO2 levels and cooling the planet.
Extreme heat can cause an overreaction in the ocean, leading to rapid CO2 absorption and cooling.
This process will take hundreds of thousands of years and won't affect humans in the near future.
