to the coastline, into the marine regions where you do get some warming, and some of the warmer spots we have been seeing, though spots we have been seeing, though spots a bit further north, these are some the places that are experiencing warmer weather and they are enhanced by local phenomena like downslope winds that come from some of the higher elevations, as the air goes down because it warms up, and that aids in increasing the temperatures on top of it. it is indeed a land of extremes. that temperatures on top of it. it is indeed a land of extremes. at its lowest, it indeed a land of extremes. at its lowest. it got indeed a land of extremes. at its lowest, it got to indeed a land of extremes. at its lowest, it got to -80 indeed a land of extremes. at its lowest, it got to -80 celsius i indeed a land of extremes. at its lowest, it got to -80 celsius - i indeed a land of extremes. at its i lowest, it got to -80 celsius - i am lowest, it got to 80 celsius i am thinking of th
