So when is the next ice age going to start, /sci/? Some people think never, some people think it will happen this century.

Tomorrow.
The day after tomorrow.
PBS Space Time actually did a great 10-minute documentary on this.

Those people are idiots. Probably not any time soon.

Double dynamo (en.m.wikipedia.org/wiki/Solar_cycle)
In 2015, a new model of the solar cycle was published. The model draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its Convection zone. Model predictions suggest that solar activity will fall by 60 per cent during the 2030s to conditions last seen during the 'Little ice age' that began in 1645. Prior models included only the deeper dynamo.
The model features paired magnetic wave components. Both components have a frequency of approximately 11 years, although their frequencies are slightly different and temporally offset. Over the cycle, the waves fluctuate between the Sun's northern and southern hemispheres.
The model used principal component analysis of the Magnetic field observations from the Wilcox Solar Observatory. They examined magnetic field activity from solar cycles 21-23, covering 1976-2008. They also compared their predictions to average Sunspot numbers. The model was 97% accurate in predicting solar activity fluctuations.

Enjoy what's left of the Modern Warm Period.

Temperature has been rising even as solar irradiance falls. I wonder why.

Patience. The prudent investor bets on solar cycle 25.

Less ozone layer on Earth, global warming, climate change, take your pick of meme.
