A wholesale corruption of science underlies the UK Government's insistence that gas from fracking offers a 'low carbon', low cost route to energy abundance, writes Paul Mobbs. On the contrary: it's expensive, over-hyped - and just as bad for climate change as coal.

Natural gas is meant to be a far lower carbon fuel than coal, writes Steve Horn. But a new study shows that methane leaks from gas power plants and oil refineries are 20-120 times higher than thought. And with methane a greenhouse gas almost 100 times stronger than CO2 over 20 years, the leaks are equivalent to about a tenth of the US's CO2 emissions.

Brazil's newly elected Dilma Rousseff is committed to completing the disastrous Belo Monte dam, writes Helle Abelvik-Lawson. Worse, she looks certain to press ahead with the industrialisation of the Amazon, with 61 hydroprojects in the pipeline. And new scientific findings about the massive climate impacts of tropical forest dams are not about to stop her.

The key study that justifies the Government's claim that fracking is a climate change 'solution' is based on serious scientific errors, writes Nick Cowern. Not only has the Government failed to correct them, but it is now delaying the publication of a new official report that would reveal the truth - that fracking is considerably worse for the world's climate than coal.

The decline of Arctic sea ice demands a response, writes Matthew Worsdale. As Arctic temperatures rise, so does the danger of huge eruptions of methane - a powerful greenhouse gas - that will tip the climate into 'hot'. The only solution is geo-engineering.

The Earth faces an imminent crisis caused by runaway Arctic warming. So says climate campaigner John Nissen, who travelled to COP20 in Lima to impress the dangers on delegates - and urge them to emergency action to cool the Arctic before it's too late.

Just imagine: gas for your cooking and heating made by composting home-grown British grass, writes Almuth Ernsting. What's not to like? Well, it would need almost all the UK's grassland to match our gas demand, leaving cows and sheep to starve or forcing them into sheds to eat foreign-grown feeds. And methane leakage could easily wipe out any climate benefit.

The latest IPCC report urges a dash for gas to allow us to reduce the burning of coal, including shale gas from fracking. But as Alex Kirby reports, their calculations appear to be based on an arithmetical flaw.

If the UK really wants 3.2GW of 'baseload' power in Somerset, then the Hinkley C nuclear power station is not the only way, write Marie-Louise Heddrich, Thorsten Lenck and Carlos Perez Linkenheil. Wind power with 'wind to gas' plant and CCGT gas power stations could do the same - faster, cheaper, more flexibily, and at much lower technical and financial risk.

A new report on fracking and climate change from the Task Force on Shale gas presents a rosy picture of the fuel's role as a climate-friendly 'bridge' to a renewable energy future, writes Oliver Tickell. But the truth is the precise opposite - it's a climate disaster that will only delay the arrival of clean energy.

Permafrost is much more sensitive to warmer temperatures than previously known, writes Alex Kirby. A new study shows that every 1C of warming could melt 4 million sq.km of frozen soil, releasing huge amounts of methane and carbon dioxide to add to the warming. It's time to start meeting those Paris targets!

A full-scale rush for shale gas would increase emissions, writes Erik Bichard, giving the lie to politicians' claims that fracking is 'climate friendly'. A new study in Nature shows that abundant shale gas would cause CO2 emissions to rise by a median 4.5%. When 'fugitive' methane is included the figure rises to 9.5%.
