The Arctic and Antarctica are poles apart when it comes to the effects of human-fuelled climate change, scientists said on Friday: in the north, it is melting sea ice, but in the south, it powers winds that chill things down. The North and South poles are both subject to solar radiation and rising levels of climate-warming greenhouse gases, the researchers said in a telephone briefing. But Antarctica is also affected by an ozone hole hovering high above it during the austral summer.
