What Ha-Shem wants to do with the weather is not really something we can “dictate”. Whether “climate change” is good or bad is subject to debate (warm weather means fewer deaths from snow and ice and cold, and a longer growing season). The climate has been changing constantly throughout our history (which is longer than most Americans “remember”). During the period of Bayis Sheini and during the period of the Rishonim it was warmer than at present, based on historical records of what crops grew where, and what rivers froze in the winter. Cooler periods such as the “Dark ages” and the Early Modern Period tended to be associated with famines and falling populations, and often horrific migrations (e.g. western European invading the Americas and doing many bad things to the inhabitants).
As climate has been constantly changing (and if you hold by paleontology, it appears that at times Greenland was green, and Antarctica was tree covered as well), it would seem that davening for a particular climate might be a bet dubious, though one supposes there is no harm is asking Ha-Shem to violate the natural order. Politically, our leaders should be wary of anyone asking for people to give up their standard of living in the belief that it will affect the weather, and suspicious that the “environmentalists” have developed a quasi-religious in their dogmas going far beyond science or public policy.
