There's a problem in Antarctica.
Most climate change models say ice around the southern continent should be decreasing. It should be melting as the planet heats up.
But sea ice around Antarctica isn't shrinking. It's been growing.
"Since the satellites went up – and that's about 30 or 40 years of records – there's been a gradual trend toward more sea ice around Antarctica," say Dr Natalie Robinson, a marine physicist at Niwa, New Zealand's Institute for Water and Atmospheric Research. "Which is not what you'd predict in a warming ocean."
Frozen icebergs in the Ross Sea. "There's something particular going on with the Ross Sea," Robinson says.
This sort of thing makes climate change skeptics shout from the roof tops. Obviously the world isn't heating up!
