How do humans affect the Earth’s climate?
They allow the sun to reach and warm the Earth鈥檚 surface then block the warmth from escaping back into space. Human activities, including those mentioned above, have continued to increase and have upset the balance of the natural system for several greenhouse gases: methane, nitrous oxide, fluorinated gases and especially carbon dioxide.
What are GHGs and how do they affect the climate?
While most GHGs are naturally occurring, human activities have also been leading to a problematic increase in the amount of GHG emitted and their concentration in the atmosphere. This increased concentration, in turn, can lead to adverse effects on climate.
What would happen if there was no carbon dioxide on Earth?
Remove carbon dioxide, and the terrestrial greenhouse effect would collapse. Without carbon dioxide, Earth’s surface would be some 33 C (59 F) cooler. Greenhouse gases occur naturally and are part of our atmosphere’s makeup.
How has the burning of fossil fuels affected the environment?
Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
