Greenhouse Gases Observations 1957-2100: Past, Present & Future

Summary

This document outlines a lecture titled "Greenhouse Gases Observations 1957-2100: Past, Present & Future" delivered by Dr. Manvendra Dubey. The core challenge addressed is the accelerating rise of greenhouse gases and their impact on climate change. The lecture traces long-term CO2 observations, noting that vegetation and oceans soak up half of human CO2 emissions. It also highlights international agreements and novel observational techniques, such as those used for national CO2 budgets (2015-2020), coal mine emissions (2013-2021), and the largest US methane anomaly at Four Corners. The discussion also covers the future trajectory of CO2 and the efficacy of decarbonizing efforts.
