Charon's winters are cold, with polar temperatures only a few degrees higher than absolute zero (minus 459.67 degrees Fahrenheit, or minus 273.15 degrees Celsius) at coldest.

Not exact matches

Nine thousand years ago, they survived frigid year - round temperatures in animal - skin tents some 500 kilometers north of what is now the Russian mainland, and they were the only people ever known to hunt large numbers of polar bears without firearms.

Yet the global average temperature differences corresponding to these radically different climates were only about 5 degrees C in the tropics and 8 degrees C in polar regions.

Since PSCs are very sensitive to temperature, cold winter vortex conditions often presage a large ozone depletion the following spring (note that polar ozone depletion only occurs in sunlight and so is a spring time phenomena in both hemispheres).

For example, in Earth atmospheric circulation (such as Hadley cells) transport heat between the warmer equatorial regions to the cool polar regions and this circulation pattern not only determines the temperature distribution, but also sets which regions on Earth are dry or rainy and how clouds form over the planet.

Nine thousand years ago, they survived frigid year - round temperatures in animal - skin tents some 500 kilometers north of what is now the Russian mainland, and they were the only people ever known to hunt large numbers of polar bears without firearms.

The global average temperature calculations cover 97 - 98 percent of the earth's surface, excluding only the most extreme polar latitudes.

That energy only gets back to the surface in polar regions, and so it does not affect the temperature of the ocean surfaces in non-polar regions — probably about half of Earth's surface.

Global temperature compared with the result for integration over the region from 64 ° N to 64 ° S, which covers 90 % of Earth's surface, excluding only polar regions.

A forcing of 12 — 16 W m − 2, which would require CO2 to increase by a factor of 8 — 16 times, if the forcing were due only to CO2 change, would raise the global mean temperature by 16 — 24 °C with much larger polar warming.

As a result, only 1 out of 7 Global or Land / Ocean (ie, global less polar regions) temperature indices shows a negative trend over that period (HadCRUT4 -0.002 + / - 0.059 C / decade).

We're only concerned about polar temperatures in this case.

â $ œThe polar regions are experiencing the most dramatic increase in average temperatures due to global warmingâ $ only in computer models.
