The Greenhouse Effect

The greenhouse effect is the process through which is trapped near Earth's surface by substances known as 'greenhouse gases.' Imagine that these gases act like a blanket surrounding our planet, helping to maintain a than it would have otherwise. Greenhouse gases include , methane, ozone, nitrous oxide, chlorofluorocarbons, and water vapor.



Scientists have determined that plays a crucial role in maintaining the stability of Earth's atmosphere and global temperatures. Greenhouse gases are a vital part of the atmosphere, and in maintaining life on Earth. However, in the last century, human activities, primarily from burning have led to the increased release of carbon dioxide. This carbon had been stored deep below the surface of the planet. Digging up and burning these fossil fuels have disrupted Earth's atmospheric balance. This has led to an increase in carbon dioxide in the atmosphere and ocean. Levels of carbon dioxide in Earth’s atmosphere has been rising consistently for decades and trap extra heat near Earth's surface, causing to rise, leading to human accelerated climate change.
