Global Warming.
The carbon dioxide (CO2) levels in the Cretaceous were 1,700 parts per million. That is 6 times the modern pre-industrial level (the amount of CO2 before the industrial revolution). The higher CO2 levels may have been partially responsible for the warm average temperature during the Cretaceous (4 C [7.6 F] above modern temperature).
No, global warming is a rise in the temperature of the earth. Global warming is causing climate change.
The rise in temperature is called Global Warming. This global warming of the earth is causing Climate Change. These two things are not the same thing.

No, the global sea level was high.
Maintain a stable global temperature. Human induced global warming increases the global average temperature.
