Greenhouse Gas Emissions
Quick fact
Over 75% of greenhouse gas emissions come from human activities like burning fossil fuels and deforestation.
Why this is interesting
Did you know that the same gases keeping Earth warm enough for life are now causing it to overheat?

Understanding Greenhouse Gas Emissions
Greenhouse gas emissions are gases released into the atmosphere that trap heat, creating a 'greenhouse effect'. While this process is natural and essential for life on Earth, excessive emissions from human activities are causing global temperatures to rise, leading to climate change. Common greenhouse gases include carbon dioxide, methane, and nitrous oxide.
A deeper explanation
Greenhouse gas emissions work by absorbing heat from the sun that would otherwise escape into space. This trapped heat warms the planet, but when emissions increase beyond natural levels, it leads to an imbalance in Earth's climate system. These gases are primarily produced through industrial processes, transportation, and agriculture, making them a key focus for mitigating global warming.
