In this video, I talk about our latest paper on the Total Solar Irradiance (TSI) measurements in the satellite era, 1978-present. TSI represents the amount of energy reaching the Earth from the Sun. Scientists have been debating what trends, if any, there have been in TSI since the first TSI satellites were launched in 1978. Some scientists have claimed that there has been almost no long-term changes other than an 11-year up-and-down cycle tracking the sunspot cycles. Others have suggested that there have been additional multi-decade-long TSI trends between each cycle. Here, I dig into these debates and presents the new results that will change our understanding of this ongoing scientific mystery. Link to the study: 🔹 R. Connolly, W. Soon, M. Connolly, R.G.
