1.5 degrees away from total meltdown


We now have a number. Scientists from Oxford University say an increase of merely 1.5C will be enough to send the world reeling into an Apocalyptic scenario.

This increase in temperature will begin to melt Siberia's permafrost. Covering roughly a quarter of the Northern Hemisphere's total land surface area, the melted permafrost could release hundreds of GIGATONNES of methane and carbon dioxide into our atmosphere.

Though scientists claim that this type of melting could take decades to reach, the fact remains: in the spectrum of billions of years, mankind's occupancy his been minimal, yet disastrous.

Compare our time on Earth to the stalactites and stalagmites studied in Siberia. They've formed over hundreds of thousands of years from melting permafrost dripping into the caves. Through ice ages and vast civilizations, warming periods and wars, they've grown and shrunk with the environment. Scientists can measure individual stalactites and stalagmites much like loggers can measure the age of trees -- by cutting into them. (Only scientists use radio-carbon dating instead of saws.) They're then able to examine growth and decay rates, which can be linked to specific periods in history.

Scientists discovered that Siberian stalactites experienced rapid growth during a period dating back 400,000 years, when temperatures were 1.5C higher than today. This finding indicates that permafrost will melt just as quickly again if temperatures rise to a similar level.

Presently, the global temperature is approximately 0.6C-0.7C above pre-industrial revolution levels.

Anton Vaks, of Oxford's Earth Sciences department and one of the chief scientists on the Siberian team, hinted that their findings could have an affect on energy infrastructure, including the laying of natural gas pipelines and future drilling operations. Oh, and one more thing: it could send the world into complete, and total chaos. "Although it wasn't the main focus of our research, our work also suggests that in a world 1.5C warmer – warm enough to melt the coldest permafrost – adjoining regions would see significant changes. Mongolia's Gobi Desert could become much wetter than it is today."

New oceans, drowning our deserts. Coastline cities under water. Sounds like the plot of a Hollywood movie, though I assure you -- the threat is all too real. We need to gain an appreciation for consequences, and the domino-effect our every decisions, even the simple ones, have on the rest of the world. Leaving the water running while brushing your teeth. Leaving that extra light on when you're not even in the room. These things seem trivial, and yet they add to the overall problem of global warming and energy consumption.

Consumption has been taken off the table of debate, since democracies often equate consumption with personal freedom. So then, what can we do? We must re-evaluate our means of energy production and distribution. A good way to start? The SH-box by NRGLab -- a device designed as a cost-effective alternative to carbon emitting fuel sources.

We will decide the world we live in. Whether that's a good or bad thing remains to be seen. Every pipeline feeds our consumption habits, which warm the planet, making it harder to lay more pipelines, which makes gas more expensive, and people poorer and more stressed. The end of the world doesn't always lie at the bottom of an ocean. Sometimes, it lies at the bottom of ourselves.

  1. Very well put. I like the way you phrased this at the end. The end of the world won't come with a bang, like they used to think with the atom bomb. sure, maybe it does end like that, but i think the world will end slowly, one person at a time.
