Deep beneath the rugged moorlands on Marsden Moor is a vast carbon store which experts believe could hold significant answers in the fight to reverse climate change.<br /><br />This landscape near Huddersfield, managed by the National Trust, has been the subject of volunteer surveys to uncover its carbon capturing potential.<br /><br />They say peat here, carbon dated to stem as far back as 10,000 years ago, shows it could capture carbon which would otherwise be vulnerable to being released.<br /><br />A volunteer survey group, working with experts from the University of Leeds, have been assessing a 350 hectare site known as Blakely Clough in the Wessenden Valley.<br /><br />Calculations suggest stores could be as strong as 300,000 tons - equivalent to the carbon dioxide emitted by using up to 98m gallons of diesel or charging 121bn phones. <br /><br />Video: The National Trust
