تآكل طبقة الأوزون وارتفاع درجة حرارة الأرض: الاحتباس الحرارى

The video discusses the visible effects of climate change, focusing on glacier melting in Washington, USA. It highlights historical changes in glaciers from 1928 to 2003 and the global reduction in ice density. Scientists agree on global warming but debate CO2's role. Future predictions include widespread floods and ecosystem damage. Volcanic eruptions in 1980 emitted significant CO2, but human activities contribute far more annually.
