Contrails

Our time in Wales so far has been the most glorious weather of the march. In Govilon on Wednesday we stayed in a Baptist Chapel with fantastic views across the valleys.

This morning I was lying with Chira and Dwijen starring at the clear blue sky.Dwijen and Chira were once again surprised by the number of planes flying over head. Fantastic white contrails were left in their wake, which as all you knowledgable people know, also have a warming effect on our planet.

I've gained a reputation as the plane man on our march; Christian Aid staff gave me a paper plane present a couple of weeks ago.

Aviation is not a big issue because it is the greatest contributor to climate change. There are so many ways we use fossil fuels no one way is the biggest.

In the UK flying makes up 13 per cent of our contribution to climate change, and emissions from aviation are growing by around 5 per cent every year.

The reason aviation is so important in the UK is because government policy is most outrageously out of line with what is needed to tackle climate change. The government has to scrap its plans for massive expansion in flights or we will be unable to radically reduce our carbon emissions. First step is to get emissions from aviation included in the climate bill.
