Renowned landscape photographer Joe Cornish has spoken of his concern for climate change which he says is evident from recent pictures of the UK he has captured for the National Trust.

Speaking this morning on BBC Radio Four?s Today programme Joe said there is ?no question? that the UK is experiencing shorter winters than before.

Joe told the BBC?s James Naughtie: ?When I first moved to North Yorkshire in 1993 we would have snow on the ground many days during the year. Now we have none and that?s extraordinary.?

Joe, who lives in Northallerton, added: ?I hope it is a wake up call? One of the things that makes the British landscape memorable is the great four season climate that we have. For me there is a real kind of poignancy to losing that aspect of our weather? We are experiencing more extremes too.?

Joe believes there have also been dramatic changes in Snowdonia which he originally photographed for the National Trust in 1996. ?I returned there in January 2006 and? I found it completely free of ice and snow.?

Joe is one of the photographers whose images feature in a new National Trust exhibition entitled: ‘Exposed: Climate Change in Britain?s Backyard? (pictured).

The BBC says that some of the shots from the exhibition will appear on the programme?s website, adding that enthusiasts can email their own landscape images to for potential inclusion online alongside the National Trust pictures.

The free National Trust show is on until 11 May at Hoopers Gallery, 15 Clerkenwell Close, London EC1. It is open Tues-Fri 11am-4.30pm (open Thurs until 7pm). Tel: 020 7490 3908.

It is also due to tour the UK – visiting Nottingham, Bangor, Bristol and Belfast.

Joe Cornish is a previous winner of Amateur Photographer magazine?s Power of Photography award.
