I am striding across its peatlands taking in the views, struggling to believe that beneath my feet lies an altogether murkier story, writes Sky News reporter Rose Gretton.

Healthy peat bogs harbour huge quantities of carbon.

But increasingly, the UK's peat reserves are leaking those supplies into the atmosphere as carbon dioxide - the major contributor to climate change.

And it is all because peatlands are one of our fastest-eroding landscapes.

Carl Hawke is an ecologist with the National Trust.  He takes me to one of the many gullies that now scar the Peak District.

It is deep and wide, with unhealthy, dry-looking peat exposed near the top.

He explains that our generally warmer temperatures are accelerating the decomposition of the peat.

As it dries out, the carbon oxidises and is lost to the atmosphere as carbon dioxide.

"If the peat is lost it will end up contributing to climate change and global warming in the future in a massive way, much more than we realise," Carl said.

"Peat actually contains something like 65% of the carbon dioxide on the planet."

Peat only covers about three precent of global land surface, but it stores twice as much carbon as all the world's forests combined.

The UK has about 15% of the world's peatlands by area, storing approximately 3.27 gigatonnes of carbon.

For that reason, the National Trust says the government should make peatland conservation much more of a priority in tackling climate change. 

Ellie Robinson, assistant director of policy at the National Trust, said: "It's one of the areas where there are lots of opportunities coming through, whether it's for wildlife, water, or for carbon management.

"They could actually be looking to the win-wins in terms of tackling peatlands."

As I wrestle my welly from the thick bog, I can't help but wonder if the issue of peatland erosion has been understated and overlooked. 

Our peat bogs are degrading faster than that of other nations and there is a danger it has become the hidden carbon timebomb.
