Climate change: do the math
The truth hides more than a mile underground.
Researchers from NOAA (National Atmospheric and Oceanic Administration) have discovered startling evidence in ice cores extracted over a mile deep in Antarctic ice. The air bubbles entombed in ice revealed a high concentration of atmospheric carbon dioxide of 330 parts per million (PPM). This condition occurred about 325,000 years ago. In over three thousand centuries, the level of carbon in air had never been higher.
At the Mauna Loa Astronomical Observatory atop the island of Hawaii, climatologists measure the amount of carbon dioxide in air. CO2 is a primary “ greenhouse” gas, along with methane (also a carbon gas), and nitrous oxide. These gasses and clouds trap some of the heat radiating the surface of Earth. Like a mirror, the greenhouse gases reflect the heat energy back to earth, causing long-term warming.
Measurements have been taken daily since 1960. Today, right now, the amount is 383 PPM. It’s never been higher in three million centuries. Never. The ice cores don’t lie.
In case you’re wondering if this carbonic rise is “natural,” consider:
- 1.Since the onset of the Industrial Age, carbon emissions have grown nearly 40%.
- Global fossil carbon emissions have increased 7X since 1850. These manmade sources include petroleum, coal, natural gas, cement production, and fluorocarbons — manmade chemicals.
- It is easy to prove the difference between manmade and “natural” carbon. Manmade carbon is NOT radioactive (it has not been in the atmosphere for a long time). Natural carbon in plants, animals, soil and the atmosphere IS radioactive.
Climate change is the fallout of the greenhouse effect. Once hypothesized impacts are now daily human experience across the globe: sea level rise, coastal erosion, loss of tidal wetlands; more frequent drought, wildfire, and flooding; loss of global ice packs; impacts on seafood stocks; the rise of tropical diseases in temperate zones; forced human migration patterns; national conflicts over natural resources. As the carbon count rises, these symptoms will become more frequent.
The clear proof is in the ice and in the air. So goes carbon, so goes the quality of life. We are fast approaching 400 parts per million carbon dioxide in the atmosphere. The big four-oh-oh is the tipping point — not only for polar bears, but for homo sapiens worldwide.
But the human race is not powerless. We can change our habits, our economics, our energy production, our politics, our consumer choices. Stay tuned for future blogs. We’ll reveal solutions already available to people around the globe. We can change. We must.
