Water, and an atmosphere
Earth is the only planet known to support any kind of life.

Yes. Weather and climate are part of a global atmospheric condition or model. This means that there are no limits or distances isolating any weather condition in any point of the planet. Our planet is one and so is its climate and weather. In general, you can think of it as a sphere surrounding other sphere (our planet). Between both, there is always something in permanent flow (our atmosphere). Think it as a snow glass ball. When you want that more snow falls on one side of the featured landscape, you must shake all the ball, you cannot shake only that part. In our planet, when anywhere there is an extreme of weather or climate, in some other place is the contrary and in other place there are other changes, all is affected by extreme chnages (and small ones).
