Unfortunately, life has gotten the better of me and I wan not able to write a new article for today. But this does present an opportunity to finally share something odd I’ve discovered: Galactic Journey. It appears to be transmissions from 55 years ago, only appearing today. It almost seems like someone is blogging from the past! Click through to read part of an entry on global warming from 1958, but published in 2013!
Are you dreaming of a White Christmas? I know I am. San Diego has beige Christmases at best. If we want snow, we have to head for the mountains or manufacture the stuff.
That said, a growing consensus of scientists is concerned that White Christmases may become a rarity for everyone, not just the privileged few living in Southern California.
It’s a big world we live in. It’s so big that we still don’t have a picture of the whole thing. At some point, someone will send up a satellite that will snap a family photo of our planet, but for now, we barely can resolve the curvature of the globe with high-flying sounding rockets. It is difficult to imagine something as tiny as a single species having a profound effect upon an entire planet.
And yet, that is exactly what may be happening. Every year, humanity puts out six billion tons of carbon dioxide. It’s a relatively harmless gas as industrial byproducts go. It certainly isn’t Strontium 90 or even coal dust. But its effects are far-reaching. Carbon dioxide is transparent to light but opaque to heat, which means it lets in the suns rays, but doesn’t let heat from the Earth escape. This is called the “Greenhouse Effect.” To some extent, we rely on this effect; without it, the Earth would be much chillier.
However, the amount of carbon dioxide we are putting into the atmosphere is enough to measurably increase the Greenhouse Effect, thus increasing the global temperature. It has been predicted (and most-recently related in Asimov’s science fact article in the January 1959 Fantasy & Science Fiction) that in 350 years, the average global temperature will rise some 3.8 degrees Celsius, or a little more than half a degree per semi-century.
