Our friend “Snowfan” here reports the sun has now gone 30 days without sunspots as we progress into solar cycle 25.
A number of scientists have been warning that the earth may be heading into a cooling phase due to lower sunspot activity over the past 15 years.

The low sunspot activity comes after a 20th century of high sunspot activity – perhaps a major reason for the strong warming since 1980, a number of atmospheric physicists suggest.

The GFS forecast of global 2-meter surface temperatures for September 20-27, 2020 (black line) show a new annual low with respect to the WMO 1981-2010 climate mean. This also applies to temperatures in the southern hemisphere (SH, bold blue line).
