Sphagnum is one
type of peat moss
that's really abundant on
earth, stores a lot of carbon.
Peat moss turns out to be a
huge, hugely important plant
globally.
It arguably stores more carbon
than any other plant on earth.
OK, this is great.
This is one of the plus 9
degree warming chambers,
so this is one of the warmest
chambers in this climate change
experiment.
If we found that a
lot of that carbon
is being released at
higher temperatures
to the atmosphere
as carbon dioxide
and especially as methane, which
traps more heat than carbon
dioxide, then that would
be a worst case scenario.
Maybe, maybe not.
The warming effects,
depending on how big they are,
have the potential to do good
things for vegetated systems
or to push things over the edge.
