I can’t predict what my 4-year old will want to eat for dinner tonight or how much, but I can easily predict that he’ll be substantially bigger and heavier a year from now, and predict the change in height and weight within reasonable tolerance.

If some laypeople have not received a basic high school education and have trouble understanding variance, uncertainty, and the difference between short-term fluctuations and long-term trends, that really isn’t the fault of climate scientists.

"Scientists are dumb, and their dumb scientific, totally rational consensus, backed up by tons of data, is dumb"

They are not "the same people", though I suspect most meteorologists have a grasp of climate trends. Those are also two very different kinds of prediction. One is like trying to guess the outcome of an individual chess match, with predictions getting better as the time draws near, the other is like noticing that white has a slightly higher chance of winning over the course of very many games.
