No Global Warming For Past 18 Years

They have a list of these supposed end all feedback loops. If it were so direly delicate then there'd be all manner of extreme swings across the millenia. Yet, according to Al Gore, the climate hasn't changed hardly a lick for 400,000 years until man showed up.

No Global Warming For Past 18 Years
I've seen this quote before and it's total BS. The summer before this one we had two weeks straight of 100 degree plus weather in Eastern Washington which was absolutely unprecedented. I remember about 8 years ago Texas set a record by having 40 straight days of 100 degree weather. Last summer they had record temperatures in Iran and India I believe it was.
That 18 year stat was probably written by a Republican, which would explain why it's so wrong.
Plants take most of their carbon from the air, removing it from the carbon dioxide. People think black soils, full of carbon are good for the garden, yes they are. The carbon that comes from the soil actually does so by vaporizing into carbon dioxide and the plant uses it. It releases enzymes through it's roots that cause this release to happen. That is how I understand it from what I read anyway.

Carbon does not simply leech out of the soil as carbon dioxide. Carbon dioxide is formed by burning (oxidizing) carbon. I assure you that the roots of plants are not igniting carbon in the soil. Unless, perhaps, you're growing fire-breathing snapdragons?
Certain micro-organisms may release carbon dioxide as a part of their life process (like we do). But in general, carbon in the soil slowly undergoes chemical interactions with other soil components and ends up as just carbon compounds. Carbon does not nutritionally enrich soil, either. Fertilizer is designed to release nitrogen compounds, phosphorous, etc. into the soil for plants to use as nutrients. Carbon is not a needed nutrient, since the plants do get the bulk of their carbon needs via photosynthesis.
My only concern now is trying to predict what can possibly be the next ridiculous target for demonizing that innocent little element. We've got atmospheric feedback, oceanic feedback, now soil feedback... next our carbon cycle will probably be vilified by discovering that Alpha Centauri is sending carbon atoms across the vastness of space in a focused beam.

In a study published in this week’s online edition of the journal Nature Climate Change, the researchers showed that chemicals emitted by plant roots act on carbon that is bonded to minerals in the soil, breaking the bonds and exposing previously protected carbon to decomposition by microbes.
The carbon then passes into the atmosphere as carbon dioxide (CO2), said the study’s coauthor, Markus Kleber, a soil scientist in OSU’s College of Agricultural Sciences.
He said the study challenges the prevailing view that carbon bonded to minerals stays in the soil for thousands of years. “As these root compounds separate the carbon from its protective mineral phase,” he said, “we may see a greater release of carbon from its storage sites in the soil.”
It is our stupidity that caused this, not the carbon, carbon is only a molecule.
Concentrated chemistry is not good
I don't think carbon is the biggest problem myself
