Monthly Global-Mean Temperatures

The following is a plot of the monthly global-mean temperatures (Lenssen et al., 2019), (Hansen et al., 2010). One cycle represents one year. It shows how the mean temperature is getting out of control. By left-clicking, you can restart the animation. Update: NASA has posted a news release about the July 2023 global temperature anomaly which I included.

I work with the GISS dataset.

The following plot shows the same data.
