Global Warming

The video discusses the phenomenon of global warming, which was first noticed in the 1980s as a rise in average global temperatures. Unlike past natural climate changes, this warming is linked to human activities, particularly greenhouse gas emissions. Scientists predict significant temperature increases over the next century, which could lead to severe climate events, including droughts, floods, and storms. The melting of ice caps could raise sea levels, making coastal areas uninhabitable. To prevent these outcomes, it is crucial to control greenhouse gas emissions, despite the expected rise in global energy use. Without significant changes, global warming will continue to worsen, with potentially catastrophic effects.
