When did greenhouse gas start?

Answer 1

Greenhouse gases started millions of years ago, before life began on earth. They keep the planet warm enough for life, through the natural carbon and water cycles of the planet.

Man began producing greenhouse gases about 260 years ago, at the start of the Industrial Revolution, when we dug up and burned coal and oil for industry, transport, and later, for the generation of electricity. These fossil fuels are releasing extra greenhouse gas which is now overwhelming the natural carbon cycle.

Answer 2

Greenhouse gas emissions from human activities began to significantly increase in the late 19th century with the industrial revolution. This increase has led to a rise in the concentration of greenhouse gases in the atmosphere, contributing to global warming and climate change.
