4. Upsurge 4 C, the part of Antartic will sink and the temperature in London is 45 C in the summer.

5. Upsurge 5 C, the ice in the both poles has melted. The existence near shore will be died.

6. Upsurge 6 C, this is the end of the civilization of humans, 95 % the existence of all creatures will be extinct.
