Of or pertaining to one of the poles of the earth, or of a sphere; situated near, or proceeding from, one of the poles; as, polar regions; polar seas; polar winds.
Of or pertaining to the magnetic pole, or to the point to which the magnetic needle is directed.
Pertaining to, reckoned from, or having a common radiating point; as, polar coordinates.
The right line drawn through the two points of contact of the two tangents drawn from a given point to a given conic section. The given point is called the pole of the line. If the given point lies within the curve so that the two tangents become imaginary, there is still a real polar line which does not meet the curve, but which possesses other properties of the polar. Thus the focus and directrix are pole and polar. There are also poles and polar curves to curves of higher degree than the second, and poles and polar planes to surfaces of the second degree.
For humans, the Arctic is a harshly inhospitable place, but the conditions there are precisely what polar bears require to survive - and thrive. 'Harsh' to us is 'home' for them. Take away the ice and snow, increase the temperature by even a little, and the realm that makes their lives possible literally melts away. Sylvia Earle
We need to save the Arctic not because of the polar bears, and not because it is the most beautiful place in the world, but because our very survival depends upon it. Lewis Gordon Pugh
The entire North Polar ice cap is disappearing before our very eyes. It's been the size of the continental United States for the last 3 million years and now 40 percent is gone and the rest of it is going. Al Gore
Polar bears did very well in the warmer times. They didn't die out at all; they didn't die out in the last 10,000 years, nor during the previous interglacial, nor the one before that. So, they're just used as a deceitful heartthrob; you know, to pluck your heartstrings because the polar bears might die out. Piers Corbyn
Well, my son really loves wildlife. And everytime he draws a polar bear I want to tell him there probably won't any by the time... he's my age. That's kinda hard to deal with. Thom Yorke
