Yes, this is absolutelty true, for the northern hemisphere. During ther summer months there is a great amount of photosynthetic organisms that are able to take in carbon dioxide and release oxygen. About 80% of all photosynthetic activity is a product of the northern hemisphere. So, in the summer when there are many photosynthetic organisms taking away carbon dioxide, there are scientifically proven data sets showing the carbon dioxide decrease. Then in the winter, when all the photosynthetic organims are no longer recycling carbon dioxide, studies will show a spike in the carbon dioxide level.
This is a seasonal change that has been occurring for hundreds of years.

What a great cause-effect question. Of course it all begins with solar energy...weather, life, and such. But how that solar energy is processed depends on weather, life, and such. So there is a cycle where solar energy impacts weather, weather impacts life, and life impacts the environment. Changes in the environment impact the weather, which re-impacts life, and re-impacts the environment. And while this cycle is ongoing, solar energy continues to feed it more energy to continue on.

Carbon levels vary with the seasons. In the green seasons (spring, summer) CO2 is scrubbed by the plant respiration (intake CO2, exhale O2). In the white seasons (fall, winter) not so much CO2 is scrubbed because fewer plants are active; they are dormant. Because the vast majority of plants are in the northern hemisphere, the green and white seasons there have more affect on CO2 concentrations than the southern hemisphere does.

Solar activity is on the rise; that is contributing to global warming. But the intensity and speed of this phase of an otherwise normal cycle has been exacerbated by the pollutants mankind pumps into the atmosphere. So mankind is not causing global warming, but it is sending it to extremes never before recorded; and no one really knows what Mother Earth will do then.

Its solar activity....that is why the other plantes (like Mars) are also having climate shifts
