Aside from <PERSON>'s answer, another aspect of global warming is the change in temperature gradients and their impact on ecologies. This map will give you a sense of what parts of the United States freeze first; those dates are gradually shifting later in the year and spring temperatures are coming sooner. That's important for a couple of reasons: Freezes kill nuisance insects (and some crops), and crops are affected by the amount of heat units they're exposed to during their growing season.
For example, certain plants and insects thrive best in a given temperature range; as temperatures rise, that range tends to get shifted toward the poles. There are insect populations that remain under control because they or their brood die off in the winter because temperatures drop to or below freezing. Warming will shift that freezing line poleward, and also helps some supporting plants that were not common to spread; those insects will become a pest in a region that's not used to them. See Climate change broadens threat of emerald ash borer or Nuisance insects and climate change. (For sea life, we do see a general poleward movement; you can have a fish species that see their optimal water temperature shift by tens of miles, pushing them away from where locations where they've evolved to feed or reproduce.)
In terms of the impact on crops, here's a specific example from Yale360 about coffee production:
The Arabica coffee grown in Ethiopia and Latin America is an especially climate-sensitive crop. 876
It requires just the right amount of rain and an average annual temperature between 64 degrees Fahrenheit and 70 degrees Fahrenheit to prosper. As temperatures rise — Ethiopia’s average low temperature has increased by about .66 degrees F every decade since 1951, according to the country’s National Meteorological Agency — and rains become more variable, Ethiopian coffee farmers have suffered increasingly poor yields.
So you can see how a slight but continuing gradient shift will alter entire ecosystems and the relationships between insects and plants. In the long term ecosystems can and do adjust to changing climates, but our agriculture and supporting infrastructure is largely optimized for last century's conditions.
I was also reminded today of the cold snap that hit the United States in February 2021 and the possibility that it was due to increased wandering of the polar vortex. This band of winds that surrounds the North Pole at altitude in the winter holds in a pool of cold air. Polar winds largely exist because of the differential between polar temperatures and temperate temperatures. Though global warming is an average, the Arctic is warming several times faster than other parts of the globe, reducing that differential. So that suggests that, paradoxically, global warming can bring colder winters to some regions in some years, though the climate.gov article on the polar vortex notes that the question remains unresolved. 876
