Fossil fuels.
Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat.
What are the top 3 causes of climate change?
Carbon dioxide, methane, and nitrous oxide concentrations are now more abundant in the earth’s atmosphere than any time in the last 800,000 years. These greenhouse gas emissions have increased the greenhouse effect and caused the earth’s surface temperature to rise.
Who has the biggest impact on the climate?

- India, with 2,654 million tons of CO2.
- Russia, with 1,711 million tons of CO2.
- Japan, 1,162 million tons of CO2.

What are the 4 major contributors to climate change?
Transportation, Industry, Agriculture, and Land Use and Forestry are four global emission sectors that roughly correspond to the U.S. sectors.
What is the main driver of climate change?
But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas. Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures.

What are the top 10 contributors to global warming?
Top 10 Causes Of Global Warming
- Waste.
- Power Plants.
- Oil Drilling.
- Transport and Vehicles.
- Consumerism.

- Overfishing. Fish is one of humans main sources of protein and a lot of the world now rely on this industry.
What is causing climate change?
Carbon dioxide is the main cause of human-induced global warming and associated climate change. It is a very long-lived gas, which means carbon dioxide builds up in the atmosphere with ongoing human emissions and remains in the atmosphere for centuries.
