Global temperature anomaly and photosynthesis.

[charmedbeauty]

Hi I was just wondering if the Global Temperature anomaly fluctuates up and down rapidly be cause of photosynthesis.

see image above.

as you can see the red line fluctuates rapidly...is this photosynthesis, or is it because the average temp is not taken rather it shows max's and min's??

any links would be super awesome... I thought i remembered reading that it was from photosynthesis but I can't seem to find where.?

Thanks.

Global temperature fluctuations are not caused by photosynthesis.
