Is it true when people say temperatures havn’t risen for ??? years? No, that's a Climate Myth

A popular quote ….

But actually the temperature has risen......
Annual average global temperatures……from NASA Institute for Space Studies (GISS)

Note ….. every La Nina ‘year’ since 1998 was warmer than every El Nino ‘year’ before 1995.  

It's useful to look at average global temperatures by comparing decades.
This chart comes from the World Meteorological Organisation

The high figures in the 1930s and 1940s were produced because there were strong El Ninos over a period from about 1939 to 1942.

Since the mid 20th century global temperatures have risen, decade by decade.
