讲座简介:
I discuss evidences suggesting that solar activity affects the terrestrial climate. I pay particular attention to claims, made by different researchers, that global warming is due to an increase in solar activity and not to anthropogenic causes like, mainly, the greenhouse effect. I conclude that, although there are evidences suggesting that solar activity affects the climate at Earth, this is not the main cause of global warming. I also present studies linking solar activity with the streamflow of rivers in South America, in particular the Paraná, one of the mightiest rivers of the world.
