Yes, I did notice the food prices have risen. Especially in the years 2017 and 2018, the conditions for crops were the lest optimal. We hardly had any fruit, as most of it froze.
Sure, if the conditions aren't optimal then the plants can't provide the rest of living beings whit what they provide us all. Then there is less offspring of insects, birds and other animals, or some are too many and some too few, so the so-called food chain breaks. Those beings don't go to stores as we do, but in this way not even in stores, the supply can't last endlessly.
Actually, the suicide rate among farmers is among the highest among all professions. But there are trials to green the deserts, like in China's Gobi, or with Water Cup in India, or Green Belt in Africa to stop spreading of Sahara. If this succeeds and spreads then this will contribute to the change of microclimate. Just as Prof Emeritus Freeman Dyson says in his interview: " You build a house somewhere and the temperature around it changes." Prof Emeritus Don J. Easterbrook said in his presentation or raw data that the media don't want to publish them but they only publish the adjusted data instead. He described the adjusted data as calculating the average out of a glass of clean water and a glass of sludge.
I don't know if geoengineering causes an ice age, but it certainly makes a mess out of the weather.
What I noticed last year was that chemtrailing dries the air. One day we've got a good amount of rain, not to heavy not too much, just right. Usually, after such rain the next day the sky would be clear in the moring and towards the noon cumulus clouds would for, then in the early afternoon, some would form a cumulonimbus above the mountain or elsewhere then we'd get a shower and the cloud would drift elsewhere. The temperature usually fell for 1-2 degrees, and the sun shone again. But the day I'm describing there was heavy chemtrailing that created that milky gauze over the sky, the air was strangely dry, and the cumulus clouds didn't form, neither did the cumulonimbus.
