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.
Rising sea levels, severe draughts, the melting of the polar caps, the more frequent and devastating natural disasters all raise demand for humanitarian assistance and disaster relief. Leon Panetta
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
We'll all die out eventually. Humans will be gone. And all I'm saying is, when people worry about polar bears disappearing or whatever, it's like, 'Well that's life, things will come and go, we'll find new species.' Karl Pilkington
'The Polar Express' began with the idea of a train standing alone in the woods. I asked myself, 'What if a boy gets on that train? Where does he go?' Chris Van Allsburg
