The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks.
What is the biggest cause of climate change?
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. … Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas because it produces a “greenhouse effect”.

What are the biggest drivers of climate change?
Agriculture, food production, and deforestation are major drivers of climate change. Land is under growing human pressure and climate change is adding to these pressures.
What are the 6 major factors that affect climate?
LOWERN
- Latitude. It depends on how close or how far it is to the equator. …
- Ocean currents. Certain ocean currents have different temperatures. …
- Wind and air masses. Heated ground causes air to rise which results in lower air pressure. …
- Elevation. The higher up you are, the colder and drier it will be. …
- Relief.
