The video discusses how increased vegetation growth, known as greening, has helped slow global warming. Greening involves activities like farming, large-scale tree planting, and reforestation. The study reveals that about half of Earth's vegetated land has been greened, which helps convert sunlight to sugar and replace atmospheric carbon dioxide with water vapor, cooling the Earth's surface. Researchers estimate that global greening has reduced the rate of global warming by approximately 0.2 to 0.23 degrees Celsius.
