Meltdown: The Science Behind Climate Change

The video discusses the significant warming of Earth's surface since 1850, with the last 30 years being the warmest in the northern hemisphere in 800 years. It highlights the contrasting changes in sea ice, with increases in Antarctica and decreases in the Arctic. The melting ice contributes to rising sea levels, which have accelerated in the last century. Climate change is linked to droughts, reduced crops, and species extinction, driven by rapid industrialization and a 40% rise in greenhouse gas emissions since 1990. The USA and China are major contributors, with China recently approving numerous coal plants. The urgency for global agreements to mitigate irreversible damage is emphasized.
