unequivocally that human activity is the cause of global warming . Extra greenhouse gases emitted by
humans into the atmosphere are the main reason that Earth is getting warmer. We produce
greenhouse gases in lots of different ways.

Burning fossil fuels
Fossil fuels such as oil, gas, and coal contain carbon dioxide that has been 'locked away' in the ground
for thousands of years. When we take these out of the land and burn them, we release the stored
carbon dioxide into the air.

data on carbon fluxes resulting from human activities and natural processes

Today, there is more carbon dioxide in the atmosphere than there ever has been in at least the past 2
million years. During the 20th and 21st centuries, the level of carbon dioxide rose by 40%. The graph
in figure shows the monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii. The
carbon dioxide data on Mauna Loa constitute the longest record of direct measurements of CO2 in the
atmosphere – they were started in 1958.
