It is a signal of human-caused local weather change, fueled largely by burning fossil fuels for power.

China, the US and the European Union emit probably the most greenhouse gasses at this time, with the US and Russia accountable for the very best emissions per capita, in line with the Middle for Local weather and Power Options. The US accounts for probably the most greenhouse gasoline emissions throughout the interval from the center of the 18th century till 2017, in line with Our World in Information.
