Dr Vicky Pope, head of climate change advice at the UK Met Office is grumpy in the Guardian
Recent headlines have proclaimed that Arctic summer sea ice has decreased so much in the past few years that it has reached a tipping point and will disappear very quickly. The truth is that there is little evidence to support this. Indeed, the record-breaking losses in the past couple of years could easily be due to natural fluctuations in the weather, with summer sea ice increasing again over the next few years. This diverts attention from the real, longer-term issues. For example, recent results from the Met Office do show that there is a detectable human impact in the long-term decline in sea ice over the past 30 years, and all the evidence points to a complete loss of summer sea ice much later this century. This is just one example where scientific evidence has been selectively chosen to support a cause. In the 1990s, global temperatures increased more quickly than in earlier decades, leading to claims that global warming had accelerated. In the past 10 years the temperature rise has slowed, leading to opposing claims. Again, neither claim is true, since natural variations always occur on this timescale. For example, 1998 was a record-breaking warm year as long-term man-made warming combined with a naturally occurring strong El Niño. In contrast, 2008 was slightly cooler than previous years partly because of a La Niña. Despite this, it was still the 10th warmest on record.It doesn't matter on which side you're misrepresenting the facts: you're distorting the debate and probably damaging the chances of getting something done about the problems in the medium term.
