Old Farmer's Almanac weather predictions

With the obvious ongoing damage to this planet's ecosystem (climate change, etc.), how reliable can one expect the Old Farmer's Almanac weather predictions to be?

answer to a question.

Robert, you posted a question based upon assumption. I suggest you go back and look at previous weather predictions. 2019 was pretty spot on where I live. Helped me plan for my gardens and I've had one of the best years I have had in some time! So yea!! read it and you can use these predictions.. They are tremendous!

Your information is based on?

Exactly what evidence do you have for your "obvious ongoing damage" statement? In the 1970's we were all told about the oncoming ice age and in the 1980's we were told Florida would be under water by now.

Can you give me a heads-up on the weather for Perry, Kansas?

We have two big events coming up on September 14 and Halloween Night. Can you give me some encouragement that it will be wonderful Fall like weather in Perry, Kansas?
