With the advent of summer, I wake up every morning to peek out my window to decide what to do that day based in whether the sun is shining or not. If its nice out, I’ll go to the beach, bike-ride, swim in a pool, run outside, play soccer/beach volleyball, or do anything in my power to make sure that the indoors is unnecessary. If GOD FORBID it is cloudy, then my entire plans change.
The sun’s presence is made known now (summer) more than the rest of the year, not only by its more frequent appearance in our sky and the warmth that we are lucky enough to receive in the northern hemisphere, but also through sunburns, and tanning-salon closures that provide other telltale signs that the natural source of light is ready to be worshipped more than any other point in the year. Coincidentally, I have a tattoo of the word “Sunshine”, mainly because that was a nickname I had growing up. But when a friend asked me the other day why I had it, I started uncontrollably ranting about the power of the sun–I’m not even sure why, but maybe it was because of this pent-up energy I have had on reserve about how important a resource and power the sun is in our lives.
If you think about it, our earth system is ultimately controlled by the sun. In a brief synopsis of my late-night rant to my drunken friend (who just was looking for a simple explanation of my tattoo), I started going into something like this;
I learned in my climate class this past semester that before anthropogenic contribution to the increase in greenhouse gas concentration in our atmosphere over the past century or so, the temperature was a FORCING for greenhouse gases (which means that temperatures would increase first before greenhouse did). How did temperature randomly change? Well, these crazy inter-planetary gravitational forces called “Milankovic Cycles” would sporadically change over LONG periods of time; whether it be the eccentricity of our planets orbit, the tilt of our earth’s rotation axis or the relative orientation axis of our spin (precession and obliquity band) would change the amount of insolation (incoming sunlight) that our earth would receive in a given period of time.
Heres the Wikipedia if you want more specifics
Basically, before humans were around, the earth’s entire climate and surface composition (which inevitably changes with climate) was dictated by how much sun we receive. Going back even farther, the emergence of multi-cellular organisms can be attributed to sunlight. Sun is the essential component for processes like photosynthesis, the hydrological cycle, wind patterns, fossil fuels, and so many other essential parts of our planet. What would we be without it?
So although I might be jumping the gun here, I’m starting to believe that the Sun is somewhat like a God in the natural sense–it creates, it destroys (its powerful UV rays, if not shielded by our Ozone layer, are deadly), and I know I can say that it makes me happy and gives me hope. Hell, why would they give students school breaks during their respective summers!? They need to relish in the wonder that should be our most prized gift as a planet and species–el sol.
