Detailed explanation-1: -The current scientific consensus is that: Earth’s climate has warmed significantly since the late 1800s. Human activities (primarily greenhouse gas emissions) are the primary cause.
Detailed explanation-2: -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.
Detailed explanation-3: -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.
