El calentamiento global

The video discusses the phenomenon of global warming, highlighting its origins in the 1980s when scientists noticed unusual climate patterns. It explains the natural history of Earth's climate changes and contrasts it with the current trend of rising temperatures linked to greenhouse gas emissions. The video forecasts potential future impacts, including extreme weather events and sea level rise, and emphasizes the need for significant changes to reduce emissions and mitigate catastrophic effects.
