The Earth will most certainly get much colder and we're not far off that.

Zharkova's updated paper...

In this paper we present prediction of solar activity for the next three solar cycles and millennium using as a proxy the solar background magnetic field based on principal component analysis. Using symbolic regression analysis we present mathematical formulae for the dipole magnetic waves and calculate their summary curve, which is shown linked to solar activity index. Extrapolation of the PCs backward for 3000 years reveals the 350-400 year grand cycles superimposed on 22 year-cycles whose the occurrence has a remarkable resemblance to sunspot activity reported in the past including Maunder, Wolf, Oort, Homeric and other grand solar minima and warming periods. The summary curve calculated for the next millennium predicts further three grand cycles with the closest grand minimum, which started in 2020 and expected to last to 2053.
