22/09/19 - RADIO: In Business: Flying Green (28 mins) Flying, for many of us, is now routine. For a few of us it is a weekly, maybe even daily, event. At the same time, global protests concerned with the pressing danger of climate change and the need to reduce CO2 emissions are gaining attention and causing alarm. So, will we ever get to a point where we can indulge our flying habit and keep our conscience clear?  Katie Prescott talks to the flight refuseniks and assesses the impact they are having. Is the long-term solution to change minds or can technological advances provide a fix? Electric cars are here; small planes are already powered the same way. How long until sizeable passenger jets follow? At a number of airports around the world, planes can fill up with biofuels. But the take-up is extremely modest. While the oil price stays low, what's the incentive for airlines to go green?

28/05/19 - Football's Euro Finals will hurt the climate All four finalists in Europe’s two top football competitions are from England, the first time one country has supplied all the teams playing. That might sound like great news for English football, but it’s bad news for the climate. This Wednesday, Arsenal will take on Chelsea in the Europa League final in Baku, Azerbaijan. A few days later it’s Liverpool versus Tottenham in the Champions League in Madrid. Thousands of fans of all four clubs will be flying from England to cheer on their teams. But air travel is one of the fastest-growing sources of climate-changing CO2 emissions. It’s calculated that for every one of those fans making the return flight from London to Baku, the equivalent of 0.69 tonnes of CO2 will be released into the atmosphere. For the shorter London to Madrid return trip, the figure is 0.21 tonnes.

RADIO: Two Men and a Mule(3 x 28 mins)  From Andean Cloud Forest to Steamy Jungle. Renowned explorers Hugh Thomson and Benedict Allen join forces with their trusty mule, Washington to journey to the extraordinary Last City of the Incas, Espíritu Pampa. Deep down in the Amazon, this is where the Incas escaped when on the run from the Spanish conquistadors in the 16th Century and where the very last Inca emperor, Tupac Amaru, was finally captured and brought back to be executed in the main square of Cuzco. This arduous trek takes them down off the steep slopes of the Andean cloud-forest into the steamy jungle, down stone-laid Inca paths, across raging rivers and landslides as they trek to the last city of the Incas - Espiritu Pampa - 'the Pampa of Ghosts'.

Described as, "unspoiled" in guidebooks, on the surface the valley looks just as it did when Andrea was a child. But look closer and things have changed.

RADIO: BBC Nature, James and the Giant Redwoods Part One Ever since he was a boy, James Aldred has loved climbing trees. And over the years, James has dreamt of searching out some of the world's biggest trees including the world's tallest living tree, a Coast Redwood (Sequoia sempervirens) in Northern California called Hyperion, which measures 379.3 feet tall. (The tallest tree in Britain is a Douglas Fir in Argyll, Scotland which is about 209 feet tall). Hyperion at nearly 380 feet tall is about 3 times the height of Nelson's Column! Hyperion was discovered on August 25, 2006 by naturalist Chris Atkins and Michael Taylor. The tree was verified as standing 115.55 m (379.1 ft tall) by Stephen Sillett. It's estimated to be increasing in height at about 2cm a year. The exact location of the tree is kept a secret to prevent human traffic disturbing and causing damage to the tree or its environment.

RADIO: BBC Nature, James and the Giant Redwoods Part Two In the second of two programmes, NATURE follows James and three other tree climbers as Michael first leads them to The Grove of Titans; which as its name suggests is a grove of some of the world's biggest trees by mass. Despite the fact that James and the others had seen pictures of the trees in books and on the internet, nothing could have prepared them for the colossal size of these trees. But there was another surprise in store for James when Michael led the way to Hyperion, the world's tallest tree and not only did James get to see this tree, but he also got to climb it. It was a dream come true and an unforgettable adventure.

TV: BBC The Wildest Dream: The Conquest of Everest  British explorer George Mallory was obsessed with becoming the first person to conquer the untouched Mount Everest.

In their attempt, the modern day adventurers must free climb the infamous Second Step - a 90 foot sheer rock wall.

The impact of tourism

06/09/17 - RADIO: Costing the Earth: Tourist Tide (30 mins) Can beautiful places welcome mass tourism without environmental destruction? Tom Heap reports. There's been a summer of discontent in some of Europe's most popular tourist destinations. In Venice and Barcelona there have been a series of protests over their inundation by visitors. In the capital of the Basque country, San Sebastian, 'tourists go home' graffiti has appeared. Dubrovnik is capping the number of visitors allowed in the old city. Even the Isle of Skye told people not to come unless they had accommodation already booked. So how can the most popular places find a way to continue attracting visitors and their cash without destroying the beauty that was so appealing in the first place? Tom travels to Orkney which has become the most popular cruise destination in the UK and to Amsterdam which is trialling innovative ways to spread its millions of visitors beyond the Rijksmuseum, the coffee shops and the Red Light District.

16/11/16 - RADIO: Costing the Earth: Cruising: A Dirty Secret (30 mins) A new cruise ship terminal is planned for Greenwich. Enderby Wharf will bring holiday makers right into the heart of the UK's capital city. Greenwich is an existing pollution hotspot. Heavy traffic from nearby Trafalgar Road and the Blackwall Tunnel mean that air quality limits are frequently breached. Bringing a cruise ship into the area will further exacerbate the problem, increasing traffic bringing goods and services to the terminal. Residents have raised concerns that visiting ships would burn 700 litres of diesel an hour whilst in dock. That's the equivalent of over 650 HGV lorries idling in an already polluted part of the city. At least 9000 Londoners already die prematurely each year as a result of breathing dirty air. Southampton is a city built around its docks and so Tom Heap visits the Solent to find out how bad air pollution from cruise ships can be and asks what can be done by the industry to cut down on harmful emissions when the ships are in berth.

01/06/13 - Ecotourism Playing Key Role in Mongolia's Transition to Green Economy  Mongolia's 2.1 degree centigrade rise in temperature over the last 70 years has led to drier conditions and degradation of pasture land, placing pressure on traditional herder communities. "Climate change is happening before our eyes: it is getting dryer every year and the winters are getting longer; our pastureland can't support as much livestock and the herders now realize animal husbandry is not the only way to live," says Mr. Dashpurev. "They have guest yurts, and can take in in paying tourists for a traditional experience. The trust also contributes to the cost of solar panels to provide power and buys produce from them." For Mr. Dashpurev, there is no choice but to start looking to a greener economy that adapts to the changing conditions and does not contribute to further climate change through the mining and burning of such resources as coal.
