Global warming: is the carbon dioxide narrative a logical explanation? and: what can be done? an opinion

Humanity is facing new weather phenomena. This is explained by the greenhouse effect and the increase in carbon dioxide. However, there are considerable doubts about this simplified, monocausal hypothesis. The history of warm and ice ages is not taken into account, nor are cyclical processes in the solar system. Therefore, the enormously expensive fight against CO² is pointless and will be unsuccessful. Plants need CO², therefore, we should build greenhouses. We should take meaningful and inexpensive measures which are presented here.
