Javier,
I agree that it’s too soon for Maunder-style cold spell.
The millennial-scale solar cycle does seem to be reflected in climate. The peaks of the Holocene warm periods are all about 1000 years apart, and likewise the troughs of the cold periods.

Peaks:


Holocene Optimum: ~5 Ka
Egyptian WP: ~4 Ka
Minoan WP: ~3 Ka
Roman WP: ~2 Ka
Medieval WP: ~1 Ka
Modern WP: peak might be now but more likely in another century, two or three
Depths:
Bronze Age Collapse: ~3.3 Ka
Greek Dark Ages: ~2.3 Ka
Dark Ages CP: ~1.3 Ka
LIA CP: ~300 years ago

    Yes, the cyclicity of Holocene climate is undeniable. It is heavily contested because it means we should be warming regardless of CO2, and because it also means solar variability in the millennial time-scale is both cyclic and has a strong effect on climate. Astrophysicists hate that idea because they cannot explain it, but paleoclimatologists are very comfortable with it, because they see the evidence in multiple proxies all over the world.

    Javier,
    All the while that evidence has been mounting, year after year, for the global extent of centennial- and millenial-scale cycles, consensus “climate science” keeps trying to d@ny the existence of these observations, ie scientific facts. These inconvenient truths were already well established before the CACA c@onspiracy replaced Communism as the main challenge to peace, freedom and prosperity.

It is our attitude toward free thought and free expression that will determine our fate. There must be no limit on the range of temperate discussion, no limits on thought. No subject must be taboo. No censor must preside at our assemblies.

–William O. Douglas, U.S. Supreme Court Justice, 1952
