More ironies. One fifth of all soil carbon is stored in peat bogs. Unfortunately when industrial wind turbines are built on them, the damage turns them from carbon sinks to carbon sources thus neutralizing the point of building the wind farm.
The headline evokes some supernatural power:
Wind farms built on carbon-rich peat bogs lose their ability to fight climate change
As if the magical whirly totem stick loses the gift of weather control when placed on a peat bog?
But the real damage is not just to wallets for another pointless windfarm. Peat bogs are so much more than carbon sinks — they are also an archive of paleohistory and the ancient climate. Indeed, even though cattle, wind and rain can damage the bogs, the researchers now say the wind farms now pose the “most serious risk” of all. Apparently the vehicle access tracks create artificial streams that drain the peat. The drainage changes are pervasive and “affect the whole peatland” not just the part near the track.
The “blanket bogs” are rare, but occur from Spain to Norway in Europe as well as in Canada, New Zealand and Korea.
The paper is a thinly disguised plea from bog experts to save […]
