at least until they burn down! I have at least five tonnes of wood sequestrated in our house, which is timber framed, floored and roofed. The wood came from mature Eucalypts in our valley that I sawed up with a friend whose land they were on. It's a small contribution, in the face also of the nearby town where steel framed concrete floored brick veneered houses are being built with little regard for orientation or passive solar design. Black metal roofing is popular, as well as no eaves to keep out summer sun, and large aircon units. Some might have double glazing. As for the story about insects in forest, that's just total nonsense. Trees themselves breathe out CO2 at night, just like we do. More to the point is the combustion of wood by fungi and termites which reduces all of it ultimately back to Co2 in an old growth forest. Just a point RG about the CO2 that's important always to stress - that in pre-industrial times the CO2 decrease/increase came AFTER the fall or rise in temperature, being a result of changes to vegetation caused by the climate change. Now we see the opposite, where the rise in CO2 comes first. CC deniers always try to confound the two. |
