The summer of 1976 witnessed soaring temperatures and almost no rainfall as the entire country sweltered under the heat.

The drought eventually broke with rain in October. John Hammond is in the Wye Valley and demonstrates what happened in the atmosphere to cause the extreme conditions.Ìý He meets with weather obsessed farmer Graham Hunter Blair who remembers the drought and its effects on his farm well, thanks to his detailed records.ÌýÌý

The North Highlands of Scotland boast some of the most impressive and remote landscapes in the UK. Their stark beauty is only matched by their timeless, rugged nature. The North Coast 500 is a touring route designed to highlight these qualities and has been described as one of the best in world. Ellie Harrison journeys to one particularly challenging stretch called the Baelach Na Bà - the Pass of the Cattle. This single track road is the highest in Britain - at an altitude of 626 metres - and is famous for its winding bends and switchbacks. Ellie is joined by endurance athlete Mark Beaumont has cycled the whole NC500 in a 38 hour stint. Together they cycle up this mountain while dealing with everything the weather throws at them.

The winter of 1947 was one of the coldest on record in the UK. The North Pennines AONB Partnership wanted to preserve memories of those hard, bygone winters so set about interviewing the elderly locals who remembered them - and created an oral history archive called ‘A Winter’s Dale’. Matt Baker meets Maurice Tarn, a retired farmer who experienced the winter of 1947. Then Matt visits a family currently in the grip of winter on their hill farm. Tom and Kay Hutchinson spend their days looking after their beef herd and flock of prized Swaledale sheep. Their three children Jack, Esme and Hetty help out too. As Matt discovers, they’re a fascinating family whose lives caught the eye of a farmer’s daughter turned film director.

Lady Park Wood is an unmanaged, predominantly beech woodland that has been studied since the 1940s.Ìý This makes it the ideal place to search for scars of the 1976 drought.Ìý John Hammond is shown around by Dr George Peterken, a local ecologist who has been taking data since the late seventies.Ìý George shows John the visible scars the drought left behind on the trees of the woodland. John also meets Professor Alistair Jump, and together they take a core sample of one of the trees to see how 1976 is recorded forever in their ring patterns.

It's winter 2014 and with storms battering the British coastline with 60ft waves, it was inevitable that our wildlife would suffer.Ìý Grey seal pups, merely a few weeks old, were washed away from their mothers or stranded on the wrong side of sea walls. But the local RSPCA East Winch Wildlife Centre was the staging ground for the biggest seal rescue since its inception in the 1980s, turning everything from duck ponds to offices into temporary homes for the lost pups. Ellie Harrison joins centre manager Alison Charles and her team to see how the seals have fared. She’s also lending some muscle for that wonderful moment when some of the strongest are released back into the wild.

The winter storms last year saw major tidal surges that destroyed the sea wall at Dawlish and swept the foundations of the coastal train track into the sea. Network Rail worked around the clock to get the track back in use, but work on the seawall is still ongoing. Anita Rani catches up with Countryfile cameraman Steve Briers, who was returning home from filming the Somerset floods last February when storms hit the Dawlish coastline. Living just behind the train track, his driveway was swept into the sea and he was told to evacuate, but he made sure he documented the scenes he was witnessing.
