Trees for Carbon Capture and Global Warming
I am unsure about all the fuss over carbon emissions and the impact of humans on the environment. There is a finite amount of carbon in our world and it cycles around in solids, dissolved in water or in gaseous forms. Plants helped convert the primordial carbon gasses and volcanoes eruptions into solid carbons. Trees capture carbon and hold as wood for long periods and historically many trees fossilised into coal.
Other key examples of carbon capture include the stores of hydrocarbons in the form of tar, oil deposits and shale from which gas is now fracked. Less related to tree carbon capture is the vast quantities of limestone deposited from crustaceans and coral.
Many ecologists and scientist now believe we should invent mechanical ways of storing carbon as there is a perceived imbalance in the carbon cycle caused by human activity. I am amused by the idea of sending carbon dioxide down the mines and oil wells to be retained for some future ill defined purpose.
Personal View on Global Warming
- The above photograph of the Yorkshire Dales including a tree and dry limestone wall contains a substantial amount of captured carbon as does the peat up on the moor.
- All Yorkshire can’t compare to the Amazon rainforest or the dissolved carbon in the sea. Since I first wrote about carbon capture major advances with shale gas exploration have highlighted again the plants of eons ago that were converted into captured carbon and are now giving up their bounty to modern man.
- All the hot air about global warming and political influence isn’t going to change me or my gardening approach.
- I will garden responsibly but I do not think I will take my gardening to extremes. However, I am going to plant some trees, grow some hard carbon and hope these trees have a long and hard carbon producing life, I just regret I won’t be around to carbon date them.
Amazon Rain Forest
- This resource is often quoted as a shorthand for the ills of global warming. Is it better to use the land freed up by deforestation for human or animal food production? I don’t think there is a perfect answer but avarice and vested interest is a poor driver of policy.
- If a tree grows 10% each and every year ( at least until adult maturity) then if follows that small young trees will capture less carbon than stately relatives. There is also a potential amenity benefit from large well managed forests so lets encourage the big and beautiful.
- In National Tree Week we should be celebrating our British heritage of trees and those organisationst and woodland charities that help manage them.
