Climate Change and Its Impact

The video discusses the unprecedented heat in 2023, highlighting extreme weather events like droughts, floods, and wildfires. It explains how greenhouse gases, primarily from fossil fuels, contribute to global warming. The Paris Agreement aims to limit temperature rise to 1.5°C above pre-industrial levels, but the window to achieve this is closing. Immediate reductions in emissions and a shift to renewable energy are crucial. Methane, a potent greenhouse gas, is also a focus, with pledges to reduce emissions. Despite efforts, global temperatures continue to rise, with 2023 being a record-breaking year.
