Scientists protect a vast carbon store by chopping down millions of trees in Scotland. Peat bogs lock CO2 into the ground - planting trees there dries the bogs, thus releasing the CO2 back into the air

Bookmarked for myself, and shared over social media to raise and spread awareness.

i didn't know that!
i knew about the peat which they have used as fuel for hundreds if not thousands of years but here we go again, human intervention detrimentally changed the natural environment!!

Gotta love science. It's good they caught this mistake by man. I shared this for my science loving friends.

I find it difficult to consider National Geographic a credible source since Rupert Murdoch bought it (and fired over a hundred experienced technical writers.)

Thanks Evelyn for sharing the interesting and informative video. Not sure I agree.
Noted.

For the doubters - check out the role of peatlands ....

For example, The New Scientist ...
Peatland destruction is releasing vast amounts of CO2

A BBC GCSE support programme:
Humans and their environment > Deforestation and the destruction of areas of peat

" The importance of peat

Peat bogs cover nearly 2-3% of the Earth’s surface and are an important carbon sink,containing more ‘locked-away’ carbon than the Earth’s forests."
"the destruction of peat bogs contributes to global warming as well as destroying important habitats."

The Peat Society
Peatlands and Climate Change
"2. Peatlands represent globally significant stores of soil C that have been accumulating for millennia and currently, peatlands globally represent a major store of soil carbon, sink for carbon dioxide and source of atmospheric methane. In general, nitrous oxide (N2O) emissions are low from natural peatlands but there is evidence that those used for agriculture are releasing significant amounts of this potent greenhouse gas. Losses of peatland C from storage result from changes in the balance between net exchange of CO2, emission of CH4, and hydrological losses of carbon (e.g. dissolved organic and inorganic C and particulate organic C). The greenhouse gas (GHG) balance of a peatland depends on relative rates of net CO2 uptake or effl ux and CH4 and N2O efflux.

3. In terms of GHG management, the maintenance of large stores of C in undisturbed peatlands should be a priority."

So - you may distrust Murdoch's involvement in Nat Geo, and you might doubt -
but check the science for yourselves before rejecting this outright.

As with everything - it is worth checking back on facts, tracing sources.
It seems to me that other sources confirm the logic of this article & video.

Where environmentalists are winning battles with (oil palm) plantations in the rain forests e.g. in Borneo, Indonesia etc, the first thing they are doing is blocking the peatbog drainage canals created for the plantations, to allow the peatland to reconstitute itself ..

Found another article - Scientific American:
Peat and Repeat: Can Major Carbon Sinks Be Restored by Rewetting the World's Drained Bogs?

Bogs, swamps and mires help keep 500 billion metric tons of carbon out of the atmosphere, so preserving peatlands is emerging as a new priority


"In fact, such peatlands store as much as 500 billion metric tons of carbon—or twice as much as is incorporated into all the trees in all the world's forests—roughly 1,450 metric tons of carbon per hectare. And the United Nations Environment Programme estimates that reducing global deforestation, especially that occurring on top of peatlands, could restore some 50 billion metric tons of CO2, or nearly two years of global emissions. Although peatlands do emit methane—a potent greenhouse gas—this is more than outweighed, in terms of the overall balance of greenhouse gases in the atmosphere, by the carbon dioxide they sequester."

It seems that while natural forests are OK - the species that grow are ones that are adapted to peat conditions, the commercial plantations of trees for exploitation are NOT good, they dry out the peatland (often with canals dug to drain water that is not good for the species planted).

Once I got over the heading (how could that make sense?) I found the article fascinating. It seemed to go against everything I know, until I watched the whole video.

Very good. . . . and just shows how important it is to get the right "headline" some times.

Underlying issue here, is people are not taking time to check, investigate and ponder.

Darren, I find that happens often here on Care2. People skim an article, or just react to a heading, and go off half-cocked without understanding the issue. It can be very frustrating!

You are SO right, Julie!!! ***********************************************************
And Darren *************************************************************

I did check the basic logic before posting, and, as you say, Julie - it is clearly presented, too

As we are guided by science all should be OK, but that is not the case, right?
