Actually, those little seasonal spikes are caused by the growth of plants in the northern hemisphere (where most the world's land plants are) during the northern hemisphere summertime. They are not caused by temperature per se, which if you think about it, doesn't even make sense since the seasonal cycles of the earth's two hemispheres are not in sync.
