Plane sailing to disaster Aircraft and ships must not be exempt from emissions cuts THE Paris climate agreement, sealed last December, was a first in many respects: the first truly international climate change deal, with promises from both rich and poor nations to cut emissions; the first global signal that the age of fossil fuels must end; the first time world leaders said we should aim for less than 2 °C of warming. Aiming for a 2 °C limit would have been considered ambitious, but leaders seized the moment and went for 1.5 °C. According to our analysis, this is achievable, but only just (see page 30). It depends on two very difficult conditions being met. One is to decarbonise the economy very quickly. The other is to find a way to suck carbon dioxide out of the air.
The immediate task, though, is to stop emitting carbon. That is not helped by a gaping loophole that has existed in climate negotiations since the first Earth Summit in Rio in 1992, and still runs right through the Paris agreement. Ships and aircraft are getting a free ride. Following on from Rio, the Kyoto protocol of 1997 – the first serious international effort to tackle climate change – also let shipping and aviation off the hook, allowing them to deal with their emissions separately. Since then, little has changed. Both industries claim they deserve special treatment because they are essential to economic development.
Prematurity is for life THE high survival rate of premature babies is one of the success stories of modern medicine. Over the past 15 years, more and more babies have survived being born earlier and earlier in their development. But the outlook is not entirely positive. As those preterm babies grow up, subtle, long-term effects of being born early are becoming apparent (see page 34). The result
of this precious lost time in the womb is a largely unrecognised epidemic of social, emotional and educational difficulties. In a typical class of 30 children, four will have been born before 36 weeks gestation, and chances are at least one will struggle as a result. That is, of course, a price worth paying for life, especially because the problems can largely be ameliorated. But as yet, there is no
It is time to call their bluff. Yes, development is important, but it can no longer be an excuse for inaction. Other economically important sectors – electricity generation, for example – are starting to do their bit. Why should aviation and shipping be exempt? Each emits roughly the same amount every year as Germany, but their emissions are still growing, unlike Germany’s. A deal that proposes to limit warming to well below 2 °C but fails to mention ships and aircraft is farcical. They both appeared in early drafts of the agreement but mysteriously disappeared in the final hours. Until this loophole is closed, the agreement is all at sea and 1.5 °C is pie in the sky. n
formal system for identifying preterm children as they enter school, nor any special provision for their needs. Teachers are widely aware that the problem exists, but don’t usually have the training or resources to intervene. Given how much we invest in acute care – it costs £250,000 to fund a preterm infant’s stay in a neonatal unit – there is a clear case for finding extra resources to support them as they get older. We can, and should, make up for that lost time. n 20 February 2016 | NewScientist | 5
