Summer Solstice
From today's Writer's Almanac:
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 entire earth is about 3 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 1/2 degrees, that makes the difference between winter and summer. 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 40º F to grow. Corn needs a temperature of 50º F, and rice needs a temperature of 68º F.

Now the big bang theory makes perfect sense!
Hi Michael,
The distance from the Sun interested me so I went googling! Here is a very interesting article that explains that the timing of the change in distance moves slowly through the whole year! http://aa.usno.navy.mil/faq/docs/seasons_orbit.html
Creation is an amazing thing . . . event . . . work of art and science . . . whatever.
Awesome, God!
I'm always amazed that when you look at science and understand the laws of the universe (at least as much as we do know), how can you not believe in an awesome God? How do some scientist discover these truths and simply think it was simply by evolution? I believe and understand an evolutionary process, but, just to know the simply facts stated in your post...I must say as you, Awesome, God!
God is indeed the creator of all!!
