Climate Change

Which of the following best describes the measurements of CO2 levels in the atmosphere since 1958?

• CO2 levels have shown steady increase since accurate measurements began.

• Co2 levels are higher in winter and lower in the summer, but the winter "highs" have increased each year and the summer "lows" have not fallen as far.

• CO2 levels are higher in the winter and lower in the summer, but the winter "highs" are higher each year and the summer "lows" are lower each year.
