General Causes of Global Warming


One of the biggest players of global warming is Carbon dioxide, I was recorded that the USA caused 40% of the world carbon dioxide emissions by burning fossil fuel to produce energy. The burning of coal also produces carbon dioxide. And this accounts for 93% of USA’s carbon dioxide emissions.
Methane also produces a threat to our environment. Methane is 20 times more effective at trapping heat in our atmosphere than carbon dioxide. There are many more causes of global warming like nitrous oxide, deforestation and city gridlock’s. these all pollute the world atmosphere cause real big global warming issues.
