•  1. I don't know what the global temperature is, but if I had to make a guess i would say it would be around 60 degrees. I think this because it is the average around the whole earth.

• 2. I think that the temperate has increased a lot over the past 100 years. Probably by around 2 degrees  or something around there but that it still a lot for only 100 years.

3. The hottest the earth has ever been is when it was being formed. The lowest it has been was probably a long time ago, over thousands of years ago.

4. I am concerned about global warming because it is ruining the planet. Also it is killing many things like animals. It is also making the ocean hotter which is killing polar bears and melting the ice caps. Also when the ice caps melt it will cover some of the earth and will raise the sea levels.
