Aren’t all these changes down to the Sun and natural factors? No. Many factors contribute to climate change. Only when all the factors are considered can we explain the size and patterns of climate change over the last century. Although some people claim that the Sun and cosmic rays are responsible for climate change, measured solar activity shows no significant change in the last few decades, while global temperatures have increased significantly. Since the Industrial Revolution, additional greenhouse gases have had about ten times the effect on climate as changes in the Sun’s output. Much of the relatively small climate variability over the last 1,000 years, but before industrialisation, can be explained by changes in solar output and occasional cooling due to major volcanic eruptions. Since industrialisation, CO2 has increased significantly. We now know that man-made CO2 is the likely cause of most of the warming over the last fifty years.
