Today is the Summer Solstice and the first day of summer in the northern hemisphere. For those of us in the north, today will be the longest day of the year and tonight will be the shortest night.
The reason it has been getting warmer and warmer for those of us in the north is not that we're any closer to the sun. In fact, the entire earth is about three million miles farther from the sun at this time of the year. The difference in the temperature is due to the fact that our planet is tilted on its axis, and at this time of year, the northern hemisphere is tilted toward the sun, receiving more direct radiation for longer periods of time each day.
It is that slight tilt, only 23 and 1/2 degrees, that makes the difference between winter and summer. As the northern hemisphere begins to tilt toward the sun, the temperature rises enough that we can take off our jackets, hats, and mittens, but more importantly the rise in temperature allows most of the plants we eat to germinate. Wheat and many other plants require an average temperature of at least 40° F to grow. Corn needs a temperature of 50° F, and rice needs a temperature of 68° F.
To Summer
by William Blake
O thou who passest thro' our valleys in
Thy strength, curb thy fierce steeds, allay the heat
That flames from their large nostrils! thou, O Summer,
Oft pitched'st here thy goldent tent, and oft
Beneath our oaks hast slept, while we beheld
With joy thy ruddy limbs and flourishing hair.
Beneath our thickest shades we oft have heard
Thy voice, when noon upon his fervid car
Rode o'er the deep of heaven; beside our springs
Sit down, and in our mossy valleys, on
Some bank beside a river clear, throw thy
Silk draperies off, and rush into the stream:
Our valleys love the Summer in his pride.
Our bards are fam'd who strike the silver wire:
Our youth are bolder than the southern swains:
Our maidens fairer in the sprightly dance:
We lack not songs, nor instruments of joy,
Nor echoes sweet, nor waters clear as heaven,
Nor laurel wreaths against the sultry heat.
