A Slowly Warming Sun
This chapter considers the role of the sun in climate change. While the sun seems constant to human perception, in reality it has been slowly getting hotter for billions of years. When compared to the impact of human activity, however, changing warmth from the sun is dwarfed by the impact of anthropogenic warming.
