Stepping up for Earth
As IPCC scientist warns the world we are pretty much out of time to limit warming.
I have read several hysterical opinion pieces on the new government greenhouse emissions scheme for meat agriculture.
All so far have been from the distorted point of view of the meat industry.
Federated Farmers states that "methane emissions are overstated by a factor of 3 or 4".
For this group, methane is a trivial matter. But in reality, methane has more than 80 times the warming power of carbon dioxide over the first 20 years after it reaches the atmosphere (an overall warming potential of more than 28 times).
Massey University's Ralph Sims, a review editor of the IPCC report, said methane emissions need to reduce by a third by 2030. Even climate experts say the IPCC missed a key opportunity to underscore the urgent need for rapid reductions in emissions of methane.
The Feds say farmers have not increased their methane in 20 years. Yet 20 years ago our methane output was far too high.
The OECD's "third Environmental Performance Review of New Zealand finds that intensive dairy farming, road transport, and industry have pushed up gross GHG emissions by 23 per cent since 1990".
And we have not even touched the land use and nitrate debacles.
Many other agricultural products (including meats) are profitable, providing protein at a fraction of the greenhouse gas impact. The world will not "starve".
We may be small but we need to pull our weight. Our children's future depends on it.
