Company Green Grazing from Vietnam is aiming to grow and sell red seaweed, as an additive to livestock feed

Why is this important?

Around the world there are around 3 billion cattle and sheep. These produce around 231 billion pounds of methane each year, which is around 10 billion metric tonnes of methane into the air. Remember that over the first 20 years (it reduces after this) methane traps roughly 80 times the same amount of carbon dioxide. So this is the equivalent of a huge amount of carbon.

To put this in perspective, if we shrink the worlds carbon emissions to zero, but are left with all this methane, we are likely to have runaway global warming anyway.

So what does this seaweed do? It essentially causes the cows and sheep to create less methane. How much? Well, while around 100 million tonnes of this seaweed would be needed, they could eliminate 98% of the methane emissions from these livestock!

In 2019 around 34.7million tonnes of seaweed was farmed, which is leading some sceptical researchers to suggest that it cannot be done. However, if we look logically, this is already enough seaweed to reduce methane emissions by 1 third – not to be sneezed at.

Another problem, is that currently Greener Grazing is restricted to only growing 1/3 of the year, as the water temperature kills the seaweed the rest of the time. However, this could be fantastic – if cross breeding can give this seaweed the ability to cope with warmer water, they might be able to meet the whole worlds demands.

More work is needed, and other tests have proved less successful in the reduction of methane, but still, this is a field, where we might be able to green peoples behaviour without requiring them to stop eating meat.

Now, of course, if meat grown in a lab could reach price parity, it may deal with this problem overnight, though it would also eliminate many peoples source of income.

Time will tell if this company is going to have a large effect or not. We need to have farmers wanting this additive, thereby creating a valuable market for coastal communities around the world.

Methane emissions that leaked from 2 fossil fuel fields in 2022, caused more warming than the whole of the UK

In many of the rich countries of the world, a great deal of effort is being put into reducing emissions. It is true, that these countries are responsible for a large amount of historical emissions. The problem is, that there are a number of so called carbon bombs that are being recognized around the world. Any of these could if unbalanced could emit so much carbon as to virtually eradicate the remaining carbon budget for the human race. These cover all sorts of things, but one that has been going on in the last year is very worrying.

Currently, the statistics state that the UK is emitting more carbon dioxide than all countries but 17. Turkmenistan however is far down the list with emissions at 47. Yet in 2022 methane emissions leaking from just two of their fossil fuel fields caused more global heating than the whole of the UK.

Flaring is blatantly done under our nose. What is clear however, is that it is far worse to let the methane escape

I have written in the past about the discovery that seaweed added to a cows diet greatly reduces methane emissions, now Morrisons wants to act

Morrisons is to have its cows given additives of seaweed in an attempt to reduce methane emissions.

Cows that can graze along the sea shore will happily eat seaweed, but adding it to all cow diets will greatly reduce emissions

This additive reduces methane emissions by as much as 80%, and given that morrisons currently has roughly 10% of the country shopping there, they have the potential of reducing cow based emissions by 8%. Now other brands need to follow Morrisons lead on this, but about 5% of the UK emissions is accounted for by the emissions of cows, which means that Morrisons move alone, should cut carbon emissions in the UK by around 0.5%, now while this is not huge, if everyone across the country chose to use this meat, 5% of emissions is a pretty substantial cut.

More to the point, with the main supermarket chains in such close competition in the UK, I find it hard to believe that others are not going to follow Morrisons lead. I for one will be happy to get our beef from Morrisons (though in our case, we have already replaced most of our beef mince with turkey mince which has a far lower carbon footprint anyway.

Methane emissions in the USA are a significant and rising problem, yet the companies deny the issue

Methane emissions are 80 times more warming that carbon dioxide. They do not stay in the atmosphere for ever, but in the short term, they could still cause the human race an enormous task which could quickly become unmanageable. Methane (natural gas) is often found in the same place as oil yet, bizarrely, extractors are generally after one or the other. By making rules on methane capture, significant quantities can be stopped from escaping into the atmosphere, never mind the fact that this methane can then be sold, greatly increasing income.

According to a recent NASA study, methane is responsible for about 25% of the global warming that has occurred since the industrial revolution.

Under Obama the central American government tightened rules on methane extraction in an attempt to deal with this issue. The larger companies engaged with the new rules, but unfortunately the smaller companies which are responsible for much of the fracking that occurs complained and the EPA under Trumps oversight (Trump had installed many fossil fuel executives into its ranks) reversed these cuts.

The industry claimed that there was not much leakage and that the problem was under control. Unfortunately this was a lie. At the same time that they were claiming tiny leaks publicly, privately they were admitting to a huge problem.

So far, these lies which are going to cost the world population have not been punished at all. What is worse, we wouldn’t know about the behaviour were it not for a secret recording made of a member of the independent petroleum association. According to the recording Ron Ness president of the North Dakota Petroleum Council told the meeting “We’re just flaring a tremendous amount of gas. This pesky natural gas. The value if it is very minimal”. A few months later, the same organisation had a lawyer state that it is not in their interests to let even a molecule of gas escape.

Yet this requires us to be fools. The most long lasting view of an oil rig is with a flame blowing out, burning off excess gas.

We need to make pollution the expensive option. If venting is the cheapest way to work, lets tax it to such an extreme level that it is worth their while to catch the waste. Of course the best way to end this practice is for the producers to go out of business. While we are moving in that direction at a reasonable speed, it is perhaps too slow for the survival of the way of life that we humans have got used to over the last few millenia. If we continue as we are, the climate we will leave for out children will not be as pleasant.

Cost of melting permafrost and resulting release of methane and carbon dioxide from the Arctic calculated by study to be as much as 70 trillion dollars

The Arctic does, unfortunately, have a built-in exaggeration of any heating. The bodies and vegetation of inhabitants of the Arctic have been locked away in the Arctic permafrost for millennia. As the Earth warms this permafrost starts to melt for the first time in millenia releasing this huge store of global warming gases.
