We know methane’s the NZ farming villain — now let’s measure it

New Zealand’s first official space mission announces ‘mission control’

New Zealand’s first government funded space mission has taken a ‘giant leap’ with Auckland University’s Te Pūnaha Ātea-Auckland Space Institute announced as the permanent host of the New Zealand based mission control centre for a global methane tracking satellite.

“MethaneSAT is a really exciting opportunity to showcase New Zealand’s science and research expertise on the world stage, while making a significant contribution to climate change by mapping agricultural emissions of greenhouse gases. It’s great to see Auckland University, with the help of Rocket Lab, playing such a key role” says Research, Science and Innovation Minister Megan Woods. Continue Reading →

what a thing to say

“Water vapour in our stratosphere can act as a very powerful greenhouse gas… water is a by-product of methane breakdown… water vapour arising from high-flying aircraft may be an important source of stratospheric water.”

At Greenhouse Gas Online we find information on greenhouse gases which disregards water vapour in an approach unencumbered with scientific principles.

Water vapour in our stratosphere can act as a very powerful greenhouse gas. The amounts of water vapour in our stratosphere are mainly controlled by the earths overall climate. However, some other significant sources exist.

As described in the methane section, water is a by-product of methane breakdown in the atmosphere. Additionally, the water vapour arising from high flying aircraft may be an important source of stratospheric water, particularly in the future with increased global air travel.

Ah, so that’s it. First, water vapour can be a powerful greenhouse gas, but only in the stratosphere. We must beware of stratospheric water vapour, which is created from the breakdown of methane and by flying aircraft.

Kids, don’t bring your homework to this site.

Fallen snow

Here’s a thread to discuss the migration of gases (or not!) through firn, or old snow, and the ramifications for past levels of atmospheric gases. When I discover how to move comments between threads, I’ll add the relevant comments from other threads.
