   12 sie 2020 · As the second most abundant greenhouse gas in our atmosphere (after water vapor), carbon dioxide (CO2) has become a direct proxy for measuring climate change. Its levels have varied widely over the course of the Earth’s 4.54 billion year history, partly driving swings in our planet’s average temperature. —.
