Do Cosmic Rays Cause Global Warming?
It has been shown recently that periodic changes in the amount of cosmic rays reaching Earth show no correlation with cloud cover. One of many examples from this research is shown below. Previously, it had been postulated that cosmic rays contributed to the formation of clouds that then contributed to, or even solely caused, global warming. Urban Heat Island Effect In examining the common sceptic/denier claim that global warming is due to the urban heat island effect, Coby Beck on Grist has been inspired to compared a picture of the Earth’s lights at night from Astronomy Picture of the Day with NASA GISS’s 2005 Surface Temperature Anomaly (see below). As Beck says, if global warming theory is an error, as it is due to high temperature anomaly readings in urban areas, why is it that many of the major temperature anomalies identified by NASA on a world scale are largely in highly rural rather than urban areas, and vice versa. Particularly note the Arctic, south Central Africa and India.
