I always wonder how certain we are about climate change. I ask myself these questions. Are temperatures really increasing or it's just we are just looking a very small time frame with a myopic perspective? Assuming that there is an anormal increase of temperature. How certain is that is man-made? My hunch is that yes, a human-made global warming is happening but I still don't have a complete conviction. Also what about these reports that are talking about a change on the solar cycle that will produce an ice age. How much can one believe these reports?
