An explorer from Much Marcle was preparing to fly back to London after leading a successful Arctic expedition.

Adam Munthe was due to head home yesterday (Thursday) from the trip to investigate the affects of climate change on nomadic reindeer herders.

The team completed a 1,000-mile journey by dog sled through some of the world's most inhospitable terrain.

Mr Munthe, of Hellens, will present the full findings to the National Geographical Society later this year.

Simon Steven, press officer for the Finnmark 2007 expedition, said: "Climate change is a reality in the Finnmark. All of the patterns of reindeer migration have changed and because it is actually warmer, the nomadic Sami are experiencing more snowfall.

"This means that the reindeer have trouble foraging for lichens and herders have to supplement their diet with hay, something that has never happened before."

Another purpose of the month-long trek, in temperatures as low as minus 35 degrees Celsius, was to document snow crystal formations to help NASA plot a Global Snowflake Network.

The actual shape of snowflakes can also show whether or not global warming is taking place.

Mr Munthe will be interviewed on BBC Radio 4's Midweek programme on Wednesday (April 18).
