Quick! Set up a trillion dollar market and figure out the science later
We got it wrong for so long
Methane is supposedly 80 times more powerful as CO2 over the short term, and we are already feeding our cows seaweed and dubious additives like Bovaer® to reduce it, and we’re trying to make steaks in labs, and create burgers out of crickets. But it turns out, the experts were wrong, yet again, and trees are absorbing more methane than they emit. So just like that, there is a major new sink to remove methane from the air, and it’s been there all the time.
The funny thing is that for years everyone was measuring the air at the bottom of the tree trunk and finding methane emissions, but when Vincent Gauci et al measured 1 – 2 metres further up the tree, not only did the methane emissions shrink to nothing, the gas started to disappear from the air around the trunk. Apparently bacteria under the bark were dining on the methane.
The team looked at trees in Brazil, Panama, United Kingdom and Sweden and estimate that all the worlds trees might already be absorbing […]

No wonder climate models can’t predict rainfall
” Until now, isoprene’s ability to form new [cloud seeding] particles has been considered negligible.”
Broad leaf tees emit up to 600 million metric tons of isoprene each year, but no one thought it mattered much. For obvious reasons it is made near the ground, and it’s quite reactive and doesn’t last long. During daylight it’s destroyed within hours. So the experts didn’t think the isoprene could help seed clouds in the upper atmosphere. But there is still quite a lot of isoprene left in a rainforest at night, and tropical storms suck it up “like a vacuum cleaner” and pump it up and spray it out some 8 to 15 kilometers above the trees. Then powerful winds can take these molecules thousands of kilometers away.
When the sun rises, hydroxyl radicals start reacting with the isoprene again, but the reactions are quite different in the cold upper troposphere. And lightning may have left some nitrous oxides floating around too. This combination ends up making a lot of the seed particles that generate clouds in the tropics. It’s almost like the forests want to create more rain…

Does anyone care? 600 million Africans don’t have electricity
They burn wood for power. Forests are razed and no one even notices. As Geoff Hill says, they warm their homes and cook their food the only way they can — by chopping down forests and converting wood to charcoal, a fuel used by the Greeks and Romans. If they had coal fired power or gas plants they wouldn’t need to cut down 400 year old trees.
An area the size of Switzerland is being denuded every year, 70% of Africa’s forests are gone, but it’s as if the rest of the world barely registers it.
Solar panels don’t work under thick cloud, and can blow away in cyclones, hydro plants won’t work in droughts, but fossil fuel plants survive bad weather. Do the Greens really care about the environment, or the poor — does the ABC, CBC or the BBC?

In Germany, praise be to Gaia, it’s Green to knock down a forest that has sat undisturbed for a thousand years to put wind farms in, and then plant saplings in a fake forest somewhere else as a carbon sink.
When will the environmentalists realize they have been taken for a ride by investment bankers and the renewables industry? Let’s help them speed up that “transition”. There’s a Red-pill moment here. File the story of the Reinhardswald, “fairy-tale forest” away for those moments when a teenager turns up to tell you how important it is to save old growth forest. Exactly, you can say… would you like too help stop the latest rapacious attack on rare heritage forest?
Being “Green” is nothing more than a badge people wear to their weekend dinner party.
NoTricksZone has reported on this environmental crime in February 2022 when the access roads started to go in. In the latest news Swiss NZZ Daily has described it as the absurdity of the German energy transition:
In the fall, the Documenta management planted oaks in the fairytale Reinhardswald near Kassel to save the climate. Now the forest is to give way to wind turbines, which […]

Look out, another knot of tortured researchers just went past. All this time we’ve been pouring money into planting trees and stealing land from farmers because we were sure that trees would cool the world. (Just like solar panels do, yeah?) But life is so complicated — for years now some researchers have been quietly wondering if more trees were actually going to warm the planet instead, but they didn’t want to say much. It turns out that while trees absorb the sacred CO2 (that’s cooling!) they also emit methane (that’s warming!), and terpenes (cooling) and isoprene (warming and cooling!) If that’s not complicated enough, then there is the albedo effect. Trees are dark, they absorb more sunlight than bare ground and snow. So depending on where they are planted, that makes for “warming”. Then some VOCs or volatile organic compounds also seed clouds.
So what’s the net effect? Who knows, it’s not like there are whole industries dependent on it…
Now they ask?
How much can forests fight climate change? Trees are supposed to slow global warming, but growing evidence suggests they might not always be climate saviours. Gabrielle Popkin, Nature

Rain rain go away, let’s chop a forest down today?
Mark Andrich and Jorg Imberger compare the rainfall patterns in different regions of southwest Western Australia. The areas where the most land was cleared show the greatest decline. They estimate that as much as 50 – 80% of the observed decline in rainfall is the result of land clearing, which doesn’t leave much to blame on CO2. The paper came out in 2012.
This fits with other researchers working on the Amazon who estimated chopping down the forests could reduce rain by as much as 90%. Once again: it’s not so much that trees grow where the rain falls, but that the rain falls where the trees grow, and the taller the trees, the better.
So the good news for Greenies is that we ought to plant more trees (and I’m all for that). But driving a Prius, building windmills, and using solar panels won’t do much for our rainfall. (It’s so strange anyone thought it would. The witchdoctors have them completely bamboozled.) The Abbott government’s plan to plant trees to sequester carbon may work, but by accident, not because of anything to do with CO2.
Oh the […]

What if winds were mainly driven by changes in water vapor, and those changes occurred commonly in air over forests? Forests would be the pumps that draw in moist air from over the oceans. Rather than assuming that forests grow where the rain falls, it would be more a case of rain falling where forests grow. When water vapor condenses it reduces the air pressure, which pulls in more dense air from over the ocean.
A new paper is causing a major stir. The paper is so controversial that many reviewers and editors said it should not be published. After two years of deliberations, Atmospheric Chemistry and Physics decided it was too important not to discuss.
The physics is apparently quite convincing, the question is not whether it happens, but how strong the effect is. Climate models assume it is a small or non-existent factor. Graham Lloyd has done a good job describing both the paper and the reaction to it in The Australian.
Sheil says the key finding is that atmospheric pressure changes from moisture condensation are orders of magnitude greater than previously recognised. The paper concludes “condensation […]
Yet more observations from the planet show that modelers misunderstand the water based part of the climate – on our water based planet.
Modelers thought that dry ground would decrease afternoon storms and rainfall over those frazzled parched lands (though I don’t remember many headlines predicting “More Drought means Fewer Storms” ). But observations show that storms are more likely to rain over dry soil. Why? Probably the dry soil heats up faster than moist areas thanks to the cooling effect of evaporation, and that in turn creates stronger thermals over dry land. Modelers assumed that wetter soils means more evaporation and thus more rain, but the moisture laden air is evidently coming from further away.
It’s another example of a point where climate modelers assume a positive feedback, yet the evidence suggests the feedback is negative. Once again water appears to be the dominant force with feedbacks (it does cover 70% of the surface). In a natural stable system the net feedbacks are likely to be negative. Positive feedbacks make the system less stable (and more scary and harder to predict.)
