According to the National Trust British peat bogs store carbon equivalent to about 20 years' worth of national industrial emissions and they are urging the government to take action to conserve them.
Two centuries of damage in some regions, including the Peak District, mean bogs are drying out, releasing carbon into the atmosphere.
The Trust wants the government to reward landowners for looking after peatlands, and allow carbon credits for good peat conservation.
"The way we manage our peat moorlands has a massive bearing on our ability to tackle climate change," said director-general Fiona Reynolds.
"But this area is almost completely neglected in terms of any coherent policy response. It is the forgotten climate change timebomb."
It is estimated that globally, peat stores twice as much carbon as forests, and the UK contains about 15% of the world's peatlands.
Healthy peat absorbs and stores carbon; but as it degrades, the carbon is released, ending up in the atmosphere as carbon dioxide.
In Britain, particularly England, peat has been badly affected by drainage which has allowed bogs to dry out, burning, overgrazing and industrial pollution. The higher ambient temperatures seen over the last decade are a new threat.
"We can only make a 'guesstimate' at how much UK peatlands are leaking carbon, because only certain peatlands have been studied in any detail," said assistant policy director Ellie Robinson.
"There are just a handful of people working on this, and there's a desperate need for new funding and co-ordination of research."
In the National Trust's High Peak Estate in the Peak District, scientists found that 1,350 hectares of degraded bog were releasing 37,000 tonnes of carbon per year - equivalent, it calculates, to the annual emissions of 18,000 cars.
The Trust is advising landowners to protect bogs by blocking gullies to raise water levels, reducing grazing, preventing fires and managing local tourism.
It wants the government to include good peat practices in stewardship schemes which reward farmers for good environmental management.
It also says landowners should be eligible for carbon credits for managing peat in such a way that emissions are reduced. Credits could then be bought and sold through mechanisms such as the European Emissions Trading Scheme.
As with all this climate change furore my reaction is simple - BOG OFF!
