saturday med.itations: A Change in the Weather

The tilt of the earth causes a varying amount of sunlight to reach each part of the planet during the year. That difference in hours of sunlight causes the seasonal changes in weather.

In some places on earth the changes are slight, but in other places they’re severe. For example, on the island of Fernando de Noronha, off the coast of Brazil, the weather varies only by a few degrees throughout the year. The hottest day in history on the island was during a heat wave when the temperature actually reached nearly 90°F.

On the other hand, the severest extremes of weather change show up in different ways in other places. Back in 1916 in Browning, Montana, for instance, the temperature dropped 100 degrees in 24 hours from 44°F to -56°F. In Spearfish, South Dakota, the temperature once rose 49 degrees (from -4°F to 45°F) in two minutes. How would you dress for weather like that?

Worldwide, the extremes are much greater, of course. The hottest day on record was in Libya, when the temperature reached 136.4°F in the shade. At the other extreme, the coldest day ever recorded was in Antarctica, where the temperature plunges to -128°F. That means that the maximum fluctuation of recorded temperature on the surface of the earth has been 265 degrees. But that’s not much compared to the tremendous fluctuations on other planets in our solar system.

For the coldest average temperatures in winter, you would need to go to a place sometimes called the “Cold Pole” in north-eastern Siberia. There the average January temperature is -59°F.

Even with these extremes in the world’s weather we can still be thankful for a Creator that established the right conditions to maintain life on earth. And we have the promise of God Himself that as long as the world remains, this will continue to be true.
