Is the earth warming? NASA has released a video that gives a hint to the question.

Deviation is the difference between an individual number and the mean.1951Year ~1980yearthe average temperature betweenstandardand in the graph0℃green circleis represented by

Many people are already aware of the progress of global warming, such as rising sea levels, changes in precipitation patterns, and melting of polar ice.IPCCThe Intergovernmental Panel on Climate Change has concluded that we humans have created waves of warming and will continue to do so.
The temperature data is from NASA’s Goddard Space Science Institute.“Surface Temperature Analysis”This video was taken from2022year8moon22of the dateAstronomy Picture of the Day(APOD, operated by the National Aeronautics and Space Administration and Michigan Technological University).
