Climate change

I once measured the temperatures outside my appartment from March 2013 until October 2016 to find out how the annual temperatures evolve. What I found out is this:

I wanted to find out how the annual average temperature evolves and if it is increasing or decreasing. As I found out and as one can see in the third figure for annual average temperatures the temperatures went up and down but with a general down trend. Whilst CO2 is increasing exponentially the temperature doesn’t follow.

The blue curve is the CO2 the red one the monthly temperatures. All I took was two thermometers and a pen and paper. I wrote down daily the lowest night and highest temperature in the shadow. I had to stop in October 2016 because I wasn’t at home to take the measurements anymore.
