Cycle City

The bulldozers have already begun work on London's 'cycle superhighways' or 'Crossrail for bikes'. Cycling enthusiasts have declared these segregated lanes to be the infrastructure which London needs to make cycling much more appealing for all. Andrew Gilligan, the Mayor's Cycling Commissioner says if Transport for London can get the engineering right then cycling in the capital will become safer and far more people might make the switch from cars, buses and trains to carbon free pedal power. Th...

Reds Return

Could the return of the Pine Marten mean the end of the Grey Squirrel takeover? Tom Heap examines emerging evidence that where Pine Marten populations are healthy, Grey Squirrel numbers crash and native Red Squirrels increase. Tom meets the researchers who found the connection in Ireland, and who are now investigating whether it's also happening in Scotland. The Pine Marten is itself recovering from years of persecution and is still only found in tiny pockets of England and Wales. If the Pine Ma...

The Price of Cheap Oil

In this week's Costing The Earth Tom Heap asks what the falling price of oil means for the environment. First thoughts would be 'not good'. Lower prices mean that people don't need to be so careful how much fuel they use so what will the consequences of this be? Will this halt the steady decline in car sales? Will people turn their heating up a notch when they're feeling chilly? Those are the direct impacts on people, but look further and could the drop in oil prices spell disaster for the renew...

Lava: A Dangerous Game

A report from the United Nations published this week highlights for the first time the international impacts of volcanoes. Previously regarded as a local problem for people in Iceland, Indonesia or Central America the UN now recognises that our interconnected world can be split asunder by relatively small eruptions. The 2010 eruptions in Iceland disrupted air travel for weeks, costing the global economy an estimated $4.9bn. In response enormous improvements are being made in the technology used ...

Greening the Green Belt

The UK's housing crisis is acute. We need to build but where? Many critics point to the ample green space which surrounds some of our most overcrowded cities and towns. The green belt celebrates 60 years since it became part of National Policy but its history stretches back far further. The idea of a stretch of land which separates the urban from the rural has been commended as the defining planning policy of the nation. This legislation is at the core of our notion of what it is to live in a 'g...

Hunting the Beefalo

A failed breeding experiment has led to a hybrid creature running riot in the Grand Canyon. The Beefalo is now growing in number rapidly and causing damage to the landscape, threatening the environment and eco-system and trashing ancient monuments of Native Americans. Yet with a hunting ban in the National Park how can they be controlled? Tom Heap goes in search of the legendary creature and the answers. The iconic bison is on the emblem on the National Parks yet in 1906 its numbers in America w...

Bristol: Green Capital?

Bristol has been named as Europe's Green Capital for 2015. Tom Heap finds out if local people will see real improvements in their city. Trapeze artists and a high wire act on a bicycle, spanning two former warehouses, heralded the start of Bristol's Year as European Green Capital for 2015. The award is a few years old now and goes to a city with outstanding green credentials and ambitions. So how is Bristol shaping up for it's year in the big green spotlight? A year ago Costing The Earth asked w...

The Ice in Iceland

Iceland is warming faster than most countries, two to four times faster than the global average temperature rise. A quirk of geography means that the island's plants and animals are having to cope with rapidly rising temperatures whilst their neighbours in the rest of northern Europe warm much more gradually. Glaciers are melting, trees are growing much faster and arable farming is suddenly possible and profitable. Tom Heap travels through Iceland to gauge the impact on the landscape and the peo...

Taming Australia

Australian Premier, Tony Abbott is determined to develop his Northern Territory. With the enormous markets of South-East Asia on the doorstep of Darwin there's huge potential for oil, gas, mining and agriculture in the thinly-populated north. Locals welcome the prospect of jobs but there's a real concern that the extraordinary landscape of the north could be lost. Mining and intensive agriculture require water in vast quantities. To get it dams will have to be built and groundwater abstracted. T...

Arctic Future

The melting sea ice of the Arctic creates opportunities and threats for the people and wildlife of the region. This week the leaders of the polar nations are in Iceland to map out a future for the region at the Arctic Circle conference. Will oil and gas production ravage the north or bring jobs and money to impoverished local people? Will Russian designs on Arctic riches provoke conflict or link the region to the global economy? And what's in it for Britain? Can our expertise in polar science he...

Where Have All the Flowers Gone?

Despite being protected on paper, many of the world's and the UK's rare plants and flowers are being targeted by thieves and smugglers. From the moment a new species is discovered it can have a high price on its head, with collectors going to the ends of the earth to source a prized specimen. Tom Heap discovers how easy it is to find rare plants for sale on the net and how such trade not only threatens those plant species with extinction but could destroy the elements within them that could help...

Power to the People

There's no doubt that 'People Power' can transform a community, when keen volunteers come together to collectively improve their lot. But what happens when People Power can be measured in watts and volts? Communities up and down the country are taking the power back - literally - from the Big 6, and starting a variety of schemes to generate their own energy. They're reducing their bills, strengthening community spirit - and helping the UK towards its renewable energy targets at the same time. An...

Texan Drought

Whilst many parts of the United States have suffered drought this summer, for Texas it's been going on for years. Wells and reservoir levels are at a fraction of what they should be and farmers and residents have been forced to face some big changes. Climatologists say this is the second worst drought in recorded history but if it continues it could soon surpass that experienced in the 1950s. Tom Heap visits cattle and crop farmer Kenneth McAlister who lives near one of the areas in 'exceptional...

The Diesel Decade

The air quality in our towns and cities has remained stubbornly filthy over the last ten years despite tightening regulations on the poisonous emissions our cars can legally belch out. That means more lung disease and more heart attacks. New research is pointing the finger of suspicion at the dramatic rise in the number of diesel vehicles on our roads. Take a look at the data from car manufacturers and it seems that diesel engines are getting significantly cleaner. Independent monitoring suggest...

Britain's Overseas Wildlife

Britain's Overseas Territories from the Caribbean to the Falkland Islands contain a treasure trove of wildlife. A new report from the RSPB reveals that 94% of unique UK species live beyond our shores. But many of those astonishing creatures are at great threat from tourist development and invasive species. To discover whether we are doing enough to protect our secret garden of species Tom Heap visits the Turks and Caicos Islands, 150 miles to the east of Cuba.

Energy Storage

Massive batteries? Compressing or liquefying air? Moving gravel uphill on ski lifts? Tom Heap looks at some of the big ideas proposed for storing energy using science or the landscape and explores which may become a reality if we're to keep the lights on. Huge investment is being made in renewable energy but as solar and wind fluctuate and are intermittent often energy goes to waste because the points at which they generate isn't when the demand occurs. So why not use that energy and store it in...

Power of Scotland

Scotland is the principal source of Britain's renewable energy as well as its oil and gas. What would independence mean for the UK energy market? Would England struggle to source clean energy? Could Scotland continue to subsidise its wind turbines and tidal energy schemes? What would a split mean for energy prices in Scotland and in the rest of the UK? Tom Heap reports from Edinburgh on an energetic debate that's certain to heat up as the Scottish independence referendum approaches. Producer: Al...
