As temperatures rise in the Southern Ocean, warmer currents are eroding the Antarctic ice sheet from below, writes Tim Radford - causing the melting rate to treble in two decades to 83 billion tonnes a year.

Increasing acidity in the Southern Ocean is slowing the growth of diatoms, reports Tim Radford. Why worry? Because these tiny plankton sustain essential marine ecosystems, and are highly effective at drawing CO2 down into the deep ocean.

Temperatures in the Middle East and North Africa could reach unbearably high levels by mid-century, writes Tim Radford - and then keep on rising. The intolerable heat would render large areas uninhabitable and give rise to a wave of 'climate refugees' seeking escape to more temperate regions.

Something scary is lurking in the melting Arctic permafrost, write Tim Radford & Oliver Tickell: 1,700 Gt of carbon. That's 53 years worth of current emissions, and if we let it melt the impact would cost the world $43 tn. Or act now, and we could preserve the Arctic ice for a seventh as much.

Scientists are calling for the urgent protection of ecologically valuable roadless areas, writes Tim Radford, as a new global map shows that roads lead to loss of biodiversity and damage to ecosystems by fragmenting habitat and providing access to exploiters.

Arctic warming is releasing ancient organic matter that's been deep-frozen for millennia, writes Tim Radford. And now scientists have discovered its fate: within weeks it's all digested by bacteria and released to the atmosphere as CO2 - with potentially catastrophic impacts on climate.
