The north pole has gotten less than https://snowfall.weatherdb.com/l/18718/North-Pole-Alaska . It's been losing significantly more than that. The poles warm faster than anything else and there isn't enough time for snow to accumulate positively. Even though there will be more snow, there will be more energy available to melt that snow.
Snow (and rain) comes out of the ocean. The warmer the oceans are, the more humid the planet gets. Humidity causes wetness, and the greater heat differentials make more violent storms.
The above link refers to North Pole, Alaska (at 64.7511°N, 147.3494°W). Which is a suburb southeast of Fairbanks, and is not the actual north pole of the planet.
Over the next 200 years the planet will most likely warm by another 2.0°C ± 0.5°C, based upon the last 100 years. Sea levels will continue to rise between 0° and 45° North latitude, and sea levels will continue to fall above 45° North latitude (actually, the sea levels remain unchanged, but the land is still rebounding from the last glaciation period 15,000 years ago, so the sea levels appear to be dropping by a significant amount). Atmospheric carbon dioxide will increase to between 450 and 500 ppmv, or even higher if we are lucky.
Judging from the duration of prior warming periods (Minoan [~300 years], Roman [~600 years], and Medieval [~300 years]), we can expect this warming cycle to last somewhere between 300 and 600 years. Since this warming period began after the end of the "Little Ice-Age" around 1850, that would put the end of this warming period somewhere between 2150 AD and 2450 AD. Although it should be noted that the Mid-Holocene Warm Period (between 5,000 to 7,000 years ago) was considerably longer in duration and much warmer than any of the prior warming periods, including this one.
Warmer climates will have some impact on the distribution of the flora and fauna. More permafrost will melt and arable lands will move further north. A warmer climate will, however, have very little effect on the overall snowfall. Yes, more ice and snow will melt when compared with today's run-off as a result of higher temperatures, but there will also be more rain and snow than today due to more evaporation. A warmer climate will also have an impact on the seas. Some species will thrive in warmer waters and it will expand their range, while other species requiring colder more nutrient-rich waters will have less area and become more constrained.
Overall, warming periods have significantly benefited humanity. We have achieved the most cultural, technological and artistic advancements during these warming periods. It is the cooling periods where humanity has suffered the most, from arrested artistic and cultural development, even technological regression, to huge pandemics that wiped out millions.
