What would happen to life on Earth if the temperature dropped?

All animal life on land would cease within 15 years as even the equatorial regions freeze hard. With the oceans also solid ice there would be no active life in the sea. Soon, the only living creatures will be those in man-made environments. They will survive as long as their will and luck hold out.

What would happen to the temperature of the earth if there was no atmosphere?

The air would still be too thin to breathe. The lack of atmosphere would chill the Earth’s surface. We’re not talking absolute zero cold, but the temperature would drop below freezing. Water vapor from the oceans would act as a greenhouse gas, raising the temperature.

What is the lowest temperature on Earth in Celsius?

What would happen if the Earth temperature rises to?

If the world temperature rises by two degrees, mountain glaciers and rivers will start to disappear and mountainous regions will see more landslides, as the permafrost that held them together melts away. By 2100, sea levels could rise by a metre, displacing 10\% of the world’s population.
