Kindling Earth

“From 1991, when the experiment began, the plots subjected to 5C warming lost about 17% of the carbon that had been stored in the top 60cm of the soil, where the greatest concentration of organic matter is to be found.
 
Scientific understanding of the complexities of soil microbial activity is still limited, but the long-term nature of the study provides valuable insights into what might be happening, and is likely to happen in future, to vast swaths of forest soils across the world.
 
While deforestation has been the focus of most research into forests’ effects on climate change, with a recent study suggesting tropical forests are turning into carbon sources rather than carbon stores as a result, the impact of warming soils has remained much of a mystery. Soils are one of the world’s biggest natural carbon sinks, along with trees and the oceans.
 
Daniel Metcalfe, of Sweden’s Lund University, said: “If these findings hold more widely across major terrestrial ecosystems, then a much greater portion of the global soil carbon store could be vulnerable to decomposition and release of carbon dioxide under global warming than previously thought.””

I understand soil. I understand positive feedback. The one leads to life as we know it. The other leads to bad things happening if not limited nicely. Soil is not just crushed rock. It’s a living thing filled to the gunnels with organic matter: bacteria, fungi, critters, roots, stuff… Warm it up or dry it out and the living things in soil will die and may oxidize, releasing CO2. If global warming is what warms it up, the resultant release of CO2 will just accelerate the warming. Hence, in my lifetime or my children’s lifetime we may be forced to live in caves to avoid the heat and eat sparse rations if human life continues at all.
 
Global warming is like lighting a fire with a match. One inputs a bit of heat at a high temperature and then the kindling ignites, causing a greater rise in heating and temperature, whereupon the rest of the stuff ignites. Don’t ignite Earth, please. Stop pumping up the concentration of CO2 in the atmosphere. It’s not OK even if it seems less expensive in the short run (according to Trumpists).
 
Wake up people! Drive smarter electrically. Heat your homes electrically and/or with geothermal heating and solar heating. Save the planet while you still can, if you still can.

    Grece really I like how they pull up 1974.
    http://journals.ametsoc.org/doi/pdf/10.1175/2008BAMS2370.1
    Please go read this. Global warming issue was first published in 1965.

    The majority in 1970s backed global warming. But there were early question in 1974 that lead to discovery of the global dimming effects. Of course a few nut cases in

    https://en.wikipedia.org/wiki/Global_cooling it even stated on the wikipedia.

    Grece the reality is the video you just linked to is presenting a known myth. There was no consensus that there would be a ice age. Majority in the 1970s said the 1970s cooling was temporary and that biggest worry was global warming. Interest enough that big oil was doing a lot of what big tobacco was doing at the time. That video take each those print media and groups in the 1970s and check them for pro tobacco articles playing down tobacco heath effects . Yes USA has had a problem with false news for a long time. Basically that video you have is a documented case of historic false news.

    I also like how you see false time magazine cover. The real time magazine of the 1974 is clear the agreed point of view says the cooling effect was temporary not a ice age.

    1975 National Academy of Sciences also said they were not sure on the data.

    As you check out all those news paper clippings from the 1970s you find that the papers behind them don’t back the clipping claims.

    Grece really its not very hard to fact check that 1970s stuff and see that the video should not be used about global warming. In fact it should be used against those claiming global warming does not exist because the mistake in 1970s was publishing stuff without the proper reports backing the story. Guess what those claiming global warming does not exist are exactly like those who claim the ice age in 1970. Woohoo for idiots who cannot learn from history even worse attempt to use that history to protect their invalid point of view.

    There is no global warming Robert, its all double-think in your head.
