Understanding Climate Change and Its Impact

The video discusses the history and development of climate change understanding, starting from early scientific discoveries in the 19th century to modern efforts in addressing climate change. It highlights key figures like Joseph Fourier and John Tyndall, the establishment of the IPCC, and recent data on global warming. The video emphasizes the importance of understanding the carbon cycle and NASA's role in tracking CO2 emissions.
