I get that for the weather forecast they use barometers for air pressure, a Doppler radar for weather fronts, but these are all short term. Farmers almanac (amongst others) can claim to know weather years in advance. How?
They site solar science, climatology, meteorology and 30 year rolling average. How do account for climate change? What about climate anomalies?

You don’t. Farmer’s Almanacs (and others) tend to have around 50% accuracy after going through scientific analysis.
You know what else averages out to 50% accuracy? Guessing general weather patterns based on historical ones.
