Expert view: as the CO2 absorption efficiency of trees declines over time “you’re going to have to keep planting more and more forests. That isn’t actually solving the problem.” Nature’s own carbon cycle isn’t easily manipulated.
– – –
Of all the solutions for a warming world, “plant more trees” seems pretty obvious, says Bloomberg News (via Phys.org).

But in New Zealand, which tested that premise by linking incentives for forestry development with its emissions trading scheme, the results have been more controversial and less effective than climate advocates hoped.

Now, after four years of frenetic planting, a prominent government watchdog has joined international agencies, industry groups and environmental advocates in calling for a radical overhaul, one that threatens a reversal of fortunes for investors in the recent forestry boom.

Nature’s carbon cycle carries on regardless.
– – –
Roughly a third of the climate cooling that forests achieve by removing carbon dioxide (CO2) from the atmosphere is offset through changes to atmospheric composition and decreased surface reflectivity, researchers report.

The findings suggest that the benefits of wide-scale forestation efforts may be overestimated and do not represent a single solution for addressing climate change, says EurekAlert.

They also highlight the urgency of simultaneously focusing on emissions reductions. Planting trees has been widely promoted as a nature-based solution to remove anthropogenic CO2 from the atmosphere to help mitigate ongoing climate warming.

However, wide-scale forest expansion may drive feedbacks within the Earth system that lead to warming.

I’ve wondered whether Climategate scientist Tom Wigley, an Australian, finally choked on all the fraud, fiddling and coverups he was witnessing from fellow members of his Climategate cabal. Steven Hayward points out that many other Climategate scientists privately had trouble swallowing the practices of their colleagues:

In 1998 three scientists from American universities–Michael Mann, Raymond Bradley, and Malcolm Hughes–unveiled in Nature magazine what was regarded as a signal breakthrough in paleoclimatology–the now notorious “hockey stick” temperature reconstruction (picture a flat “handle” extending from the year 1000 to roughly 1900, and a sharply upsloping “blade” from 1900 to 2000). Their paper purported to prove that current global temperatures are the highest in the last thousand years by a large margin–far outside the range of natural variability. The medieval warm period (MWP) and the little ice (LIA) age both disappeared.

California’s San Joaquin Valley and Central Valley [image credit: Mark Miller @ Wikipedia]


The region studied has a naturally varying climate, as do most regions of the world. One minute the article says the last few centuries there had more weather extremes than now, the next it implies the future could or will be like that again or worse, due to being ‘compounded’ by the catch-all *climate change*. File under ‘unconvincing’?
– – –
The San Joaquin Valley in California has experienced vast variability in climate extremes, with droughts and floods that were more severe and lasted longer than what has been seen in the modern record, according to a new study of 600 years of tree rings from the valley, says Eurekalert.

The researchers used the tree rings to reconstruct plausible daily records of weather and streamflow scenarios during the 600-year period.

This new approach, combining paleo information with synthetic weather generation, may help policymakers and scientists better understand – and anticipate – California’s flood and drought risks and how they will be compounded by climate change. [Talkshop comment – unsupported assertion].

The group’s paper is published in Earth’s Future, a journal of the American Geophysical Union.

Not meaning to sound harsh here, but why not try this Talkshop remedy – pull yourself together. Climate has always varied naturally, and always will. That’s it.

Researchers must find personal ways to cope with impending losses — one way is by taking small solutions-oriented actions, says Kimberley R. Miner in Nature’s Career Column.

Last September, before the rains came, my field team learnt that it was probably too late for half the blue oaks affected by California’s drought in the region in which we were working.

Because of years of ongoing drought, many of the trees would not recover from the long-term water loss and would die. The next morning, I sat outside our science team meeting and cried.

Claims of no evidence of arson were undermined by police arresting someone for starting 32 wildfires on a previous occasion, and this.

Our northern neighbor’s wildfires are wreaking havoc on American air quality, and the Left is leaping to the usual conclusions.
DOUGLAS ANDREWS

Listen closely, and you can practically hear him say it: You never want a serious Canadian wildfire crisis to go to waste.

No, Rahm Emanuel isn’t whispering into Joe Biden’s ear these days, but those on the Left know well what Barack Obama’s former chief of staff said in the days just after the 2008 election, and they certainly know “an opportunity to do things you think you could not do before” when they see one.

Take Alexandra Ocasio-Cortez, for example, who told her 13 million Twitter followers yesterday: “Between NYC in wildfire smoke and this [heat wave] in [Puerto Rico], it bears repeating how unprepared we are for the climate crisis. We must adapt our food systems, energy grids, infrastructure, healthcare, etc…

Sitka spruce forestry in Scotland


Another avoidable green fiasco in the name of climate obsession.
– – –
Millions of pounds are being spent carpeting thousands of acres of land with conifers on the basis they will lock up CO2 from the atmosphere.

But a new report shows that many of the forests springing up around the country likely add to the risk of climate change, says the Sunday Post.

Vast tracts of peaty soil are being dug up and drained in order to plant trees, unleashing a torrent of stored carbon [dioxide] into the environment.

A14 road


Competence got left behind in the rush to look climate friendly by absorbing a token amount of atmospheric carbon dioxide.
– – –
The government agency responsible for our main roads, National Highways, has admitted that over half a million trees have died beside a single 21-mile stretch of new carriageway, reports Sky News.

They estimate the cost of replanting at £2.9m.

Many tree experts say this is symptomatic of a focus on tree planting over tree care. Only growing trees capture carbon or improve habitat.

The upgrade of the A14 between Cambridge and Huntingdon, cost £1.5bn and was opened in 2020.

We looked at some of this recently, here and here. Of course the problem nowadays is that weather news is liable to be subjected to the melodrama treatment by climate obsessives. Re. the European droughts, there’s also the evidence of the ‘hunger stones’, for example.
– – –
The Holocene – the time since the end of the last glaciation – which has witnessed all of humanity’s recorded history and the rise and fall of civilisations – began only 11,700 years ago, says Dr David Whitehouse @ Net Zero Watch.

It is a relatively warm period, but how warm was it at its warmest?

What happened in the past informs current climate models placing the current global warming into perspective.

Mixed messages from climate research here. In between evidence-free waffle about ‘potential’ human influence, they report that severe drought spells are nothing new in Europe, implying climate cycles of some sort. This means attribution of such drought to human causes is debatable, as the article admits.
– – –
The 2015–2018 summer droughts have been exceptional in large parts of Western and Central Europe over the last 400 years, in terms of the magnitude of drought conditions.

This indicates an influence of man-made global warming, claims Phys.org.

However, multi-year droughts have occurred frequently in the 17th and 18th century, although not as severe.

This is the result of a new study in the journal Communications Earth & Environment.

German forest with wind turbines


The research team ‘concludes that wind power development in forests must be avoided’, if at all possible. Not what climate obsessives want to hear, but hardly surprising news. More scientific evidence of what was already known.
– – –
More than 30,000 turbines have already been installed on the German mainland so far, and the industry is currently scrambling to locate increasingly rare suitable sites.

Thus, forests are coming into focus as potential sites, says Berlin’s FVB research institute.

A scientific team from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now demonstrated in a new paper published in the scientific journal “Current Biology” that wind turbines in forests impair endangered bat species: Common noctules (Nyctalus noctula), a species with a high risk of colliding with rotor blades, are attracted to forest wind turbines if these are located near their roosts.

Far from roosts, common noctules avoid the turbines, essentially resulting in a loss of foraging space and thus habitat for this species.

This underlines the reality, whatever the numbers are. Carbon capture is nature’s job.

UK forests could store almost double the amount of carbon than previous calculations suggest, with consequences for our understanding of carbon stocks and humanity’s response to climate change, according to a new study involving UCL researchers.

For the study, published today in the journal Ecological Solutions and Evidence, the international team of scientists used a novel 3D scanning technique and analysis to assess the amount of aboveground biomass (AGB)—used to derive carbon storage—of 815 trees in a UK woodland, says Phys.org.

The team found that their results were 77% higher than previous estimates (410 t ha-1 of biomass vs. 232 t ha-1).

When they say ‘sudden’ they don’t mean short-lived. The report notes that ‘some of the events, unlike the brief flashes we recognize as solar flares, lasted for one or two years’. Only a handful of these so-called ‘cosmic barrages’ have occurred in the last 9000 years or so, according to the data.
– – –
One of the events was 80 times more powerful than the strongest solar flare ever recorded, says LiveScience.

A series of sudden and colossal spikes in radiation levels across Earth’s history could have come from a series of unknown, unpredictable and potentially catastrophic cosmic events, a new study has revealed.

Named Miyake events after the lead author of the first study to describe them, the spikes occur roughly once every 1,000 years or so and are recorded as sudden increases in the radiocarbon levels of ancient tree rings.

The exact cause of the sudden deluges of radiation, which periodically transform an extra chunk of the atmosphere’s nitrogen into carbon sucked up by trees, remains unknown.

Nature’s carbon cycle still working as expected.

Increased levels of carbon dioxide in the atmosphere have contributed to a rise in wood volume or biomass of forests in the US, according to a new study.

The research, published recently in the Journal Nature Communications, found that elevated carbon levels have led to a consistent increase in wood volume in 10 different temperate forest groups across the US, says The Independent.

By bulking up this way, trees are helping shield Earth’s ecosystem from the impacts of global warming, say scientists, including those from the Ohio State University.

Smoke from a California wildfire [image credit: BBC]


There’s a ‘fundamental design problem’, namely that the forests have an unfortunate tendency to burn down. Research finds it ‘incredibly unlikely’ that such schemes will work, and not only in California.
– – –
Researchers have found that California’s forest carbon buffer pool, designed to ensure the durability of the state’s multi-billion-dollar carbon offset program, is severely undercapitalized, says Eurekalert.

The results show that, within the offset program’s first 10 years, estimated carbon losses from wildfires have depleted at least 95% of the contributions set aside to protect against all fire risks over 100 years.

This means that the buffer pool is unable to guarantee that credited forest carbon remains out of the atmosphere for at least 100 years.

Tree planting


Hapless climate botherers barking up the wrong tree again? Carbon dioxide capture should be left to nature.
– – –
In a new paper published in Frontiers in Forests and Global Change the scientists look at the climate effects of deforestation at different latitudes, says Net Zero Watch.

The researchers find that at latitudes 50°N to 60°N – in other words essentially all of the UK – and above, deforestation contributes to global cooling, so afforestation (which has opposing effects to deforestation) will contribute to global warming.

Sheep farming in Wales [image credit: BBC]


Another example of unintended consequences caused by the irrational pursuit of climate obsessions by governments.

A fifth of Welsh farms are running at a loss and there is a risk that farmers will be priced out of agriculture by big corporations buying up farmland for carbon offsetting schemes, according to a new report on family farms in Wales.

The findings of an inquiry by the Welsh Affairs Select Committee published today (7 April) paint a concerning picture for Welsh agriculture, an industry where the average farm size is just 48ha, compared to 87ha in England, says TW News.

From pressure on incomes and land availability to a lack of opportunity for new entrants, the report highlights some of the key concerns and sets out a series of recommendations to governments to address the issues.

Storm Arwen damage 2021 [image credit: Cwmcafit @ Wikipedia]


You just know that sooner rather than later the BBC will play its climate change (meaning humans in their book) card in an article about any kind of adverse or unusual weather conditions, even if only lasting a day or two, and sure enough…so predictable and tedious. They also conveniently forgot that in the ‘Great Storm’ of 1987 which felled an estimated 15 million trees in England alone, much of the damage was in southern England, northern France and the Channel Islands.
– – –
It is the untold story of the winter storms, says BBC News.

More than eight million trees have been brought down and many are now threatened by another two named storms bearing down on Britain.

Forest managers warn that already “catastrophic” damage will be made worse by Storms Dudley and Eunice.

There are warnings that the heating climate is making our weather more severe and unpredictable, and that management and planting strategies must adapt more quickly.

Biomass on the move [image credit: Drax]


The whole ‘net zero’ thing is a scandal in many ways, but at least some MPs are noticing one of the issues, even if partly for the wrong reason. Burning trees isn’t a solution to anything apart from papering over a few of the cracks in electricity supply caused by intermittent renewables.
– – –
Burning wood to create power is a ‘scandal’, 50 MPs warn the energy minister in a letter today.

The letter – which has cross-party support – marks a major shift in political opinion over the burning of biomass, which is currently classed by the Government as a green form of energy, says the Daily Mail.

The letter says the extra emissions produced by biomass ‘are the equivalent of three million Ford Fiestas on our roads’.

Organised by Peter Bottomley, Father of the House of Commons, the letter calls for a meeting with Business and Energy Secretary Kwasi Kwarteng to discuss ending subsidies to the Drax power plant in Yorkshire.

This article starts off confident that the researchers are right – ‘we now know’ etc. – but later retreats and says ‘the cooling appears to have’ etc. But as the Little Ice Age is an interesting topic it’s worth a look.
– – –
New research from the University of Massachusetts Amherst provides a novel answer to one of the persistent questions in historical climatology, environmental history and the earth sciences: what caused the Little Ice Age?

The answer, we now know, is a paradox: warming, says Phys.org.

The Little Ice Age was one of the coldest periods of the past 10,000 years, a period of cooling that was particularly pronounced in the North Atlantic region.

This cold spell, whose precise timeline scholars debate, but which seems to have set in around 600 years ago, was responsible for crop failures, famines and pandemics throughout Europe, resulting in misery and death for millions.
