Explainer: Why the sun is not responsible for recent climate change

WebThe solar output is very nearly constant, as shown in the plot below. The range of variation is about 0.2%, so reproducible that it is often referred to as the "solar constant". But there are other aspects of the Sun's activity that are not constant, as indicated by the changing sunspot activity. WebEvery second, the Sun's core fuses about 600 million tons of hydrogen into helium, and in the process converts 4 million tons of matter into energy. This energy, which can take between 10,000 and 170,000 years to escape the core, is the source of the Sun's light and heat. is a peninsula in southern ukraine
