Methane Gas And Climate Change

Recommended Posts

NASA-led study solves a methane puzzle

Quote

A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions from global fires. The new study resolves what looked like irreconcilable differences in explanations for the increase.

Methane emissions have been rising sharply since 2006. Different research teams have produced viable estimates for two known sources of the increase: emissions from the oil and gas industry, and microbial production in wet tropical environments like marshes and rice paddies. But when these estimates were added to estimates of other sources, the sum was considerably more than the observed increase. In fact, each new estimate was large enough to explain the whole increase by itself.

So , nothing to do  with MOD thread then .

Apparently the researchers weren't allowed access.

Puzzle, what puzzle, an area overpopulated by any species is simply not sustainable.

I'd been reassured that the shelf deposits were safe for quite a while but it appears I might have been being too hopeful?

I'm sticking this here so folk might link the two.

Anyone witnessing the Boscastle storm will know how big that cloud became and just how much moisture must have flooded the strat above the event.

If you care about 'feedbacks' ,and how quickly change will now impose itself, do watch this!

Article and link to recent paper

The permafrost bomb is ticking

https://www.yaleclimateconnections.org/2018/02/the-permafrost-bomb-is-ticking/

Folk talk of 'Global warming' and so maybe miss just how important the changing cold places are?

It is the changes on Greenland/Arctic /Antarctica that most concern me and that is because change there , as this article points out , can cascade from one small flip into a sudden global flip.

We've probably all seen 'myth busters' knock over a multi tonne slab with a 'cascade' that starts with a single domino? 

That state change from ice to water appears to radically alter the speed of change that is possible and so rapidly propels us into cascades of self reinforcing change from one single, small, push.

Yamal popped up in carbuncles 2 summers ago. Prof Semiletov tells us it takes such 'carbuncles'  3 years to go from formation to 'popping' ( as we have seen from the Yamal craters that formed a few years back?)

That means that we may well have our first 'domino' fall over this coming summer.

One extra push in an arctic system packed with systems galore ready to go pop themselves (From ocean to stratosphere?)

And there's more....

Seeing as our current IPCC reports are a tad 'skimpy' on the impacts of permafrost impacts our changing understanding of their importance just means we drift further and further from the conclusions we were handed mere months ago?

Maybe this is why folk will not accept the '12 years' ( now 11) warning about us mending our ways to save our way of life?

EDIT: and yes! , time alone will tell but fancy us cleaning up our global polluting acts and then finding we needn't have bothered ....what a loss that would be for our world and its inhabitants!........
