Climate-warming gas levels rising faster than ever, scientists warn

The video discusses the alarming rise in carbon dioxide levels over the past two years, which is unprecedented in human history. Scientists from NOAA, Scripps Institute, and UC San Diego highlight the impact of CO2 on the environment and economy, noting that 2023 was the hottest year on record. Human activities, particularly the burning of fossil fuels, are identified as the primary cause of rising CO2 levels. The video emphasizes the need for the US to lead in reducing emissions and developing sustainable energy solutions. It also notes the economic toll of climate disasters, with several billion-dollar events already recorded in 2024.
