Volcanic leaks point to climate gas storage risks

Hundreds of deaths caused by volcanic leaks of carbon dioxide from Cameroon to California are worrying experts seeking ways to bury industrial emissions of the gas as part of an assault on global warming.
Governments and companies are researching how to trap carbon dioxide — a greenhouse gas released by burning fossil fuels in power plants and factories — and then entomb it safely in porous rocks deep below ground.

However, they have done little to explain the vast costs and the risk of leaks from projects that could end up burying billions of tonnes of gas and do more to slow global warming than a shift to renewable energies such as solar or wind power.
