^I admit that the specifics of climate change science are full of uncertainties, but you have to be pretty thick, and have done pretty poorly in any science class above Grade 10, if you think that there is a link between global climate patterns and predicting the exact weather forecast in a localized area.
To give you an analogy, acknowledging that elevated emissions of carbon can result in a global warming with unpredictable climate changes is like a social scientist telling you that children who grow up in low income, single parent environments are more likely than their peers to engage in criminal activity. The evidence amassed on this is pretty substantial and it can be verified as a general trend.
A weather forecast is like that same social scientist telling you that Johnny, the low income son of a single mother from Malvern will rob a Petro Canada gas station at the corner of Markham and Ellesmere Road on July 15th, 2019. In this case, you are attempting to pinpoint an exact event, and the precise unfolding of this event, as predicted, is subject to innumerable and unaccountable forces.
