Comma after "melt"
Comma after "flat"
Run-on after the second sentence.
It's "en masse" not "in mass."
"the organisms' cells" = what organisms' cells??
What would happen if the temperature of the Tundra increased?
The permafrost will melt and since the tundra is flat land bogs and shallow lakes will appear and won't drain. Rainfall will change, although I'm not sure if it will increase or decrease. Plants will also change, some will die, but others will thrive in the warm weather. Warm-blooded animals would die in mass. The animals would die because the temperature interrupts chemical reactions within the organisms' cells.
Does it sound alright? Are there any grammar/spelling mistakes?
