Trees ‘remove carbon dioxide from the atmosphere and store large quantities of carbon in their tissues.’ – Wikipedia


If absorbing carbon dioxide is the idea, which is better value for money: big technology, or plain old-fashioned trees?

On May 31, 2017, the world’s first commercial atmospheric carbon-capture plant opened for business in Hinwil, Switzerland, reports Climate Change Dispatch.

The plant, designed and operated by a Swiss company called Climeworks, is different from existing carbon-capture facilities because it filters carbon dioxide out of the ambient atmosphere using proprietary technology, rather than from industrial exhaust, which is quite common.

Climeworks claims their facility will be able to remove 900 tons of carbon from the atmosphere every year. Furthermore, its modular design will allow it to be scaled up as the demand for carbon dioxide increases.

What do they plan to do with said carbon?

American Elephants

A new survey using high-definition satellite images has found 378 million additional hectares of forest around the globe—it’s as if all of Earth’s forests just grew by 9%.

(The hectare is an SI accepted metric system unit of area equal to 100 ares (10,000 m²) and primarily used in the measurement of land. An acre is about 0.4047 hectare and one hectare contains about 2.47 acres. I don’t do metric, and assume that some of you don’t either. You can also think of it as an area of forest equal to sixty percent of the size of Australia, if that helps)
“The forests have been identified in drylands in the Sahara desert, around the Mediterranean, southern Africa, central India, coastal Australia, western South America, north-east Brazil, northern Columbia and Venezuela and northern parts of Canada and Russia.”

Map of Scottish woodlands

Map of Scottish woodlands


A related issue is that Scottish woodland is currently being invaded by an army of wind farm constructors whenever they get the chance.

The SNP’s plans to increase the amount of woodland in Scotland in an attempt to fight climate change risks damaging the nation’s “dramatic open views and vistas”, according to mountaineering and gamekeepers groups.

The Scottish Government has proposed increasing the amount of woodland cover from 17 per cent to 25 per cent by 2050, with a commitment to planting 10,000 extra hectares of trees between now and 2022 included in its draft Climate Plan, as iNews reports.

But Mountaineering Scotland and the Scottish Gamekeepers Association (SGA) are concerned that the changes could damage the nation’s wild moorland, arguing it forms a crucial part of Scotland’s “unique” landscape.

Pierre L. Gosselin provides an English overview of a video presentation in German given by Dr. Sebastian Lüning, a geologist and co-author of the book “The Neglected Sun

This is a geological context that unfortunately is lost on many people like physicists who believe their formulae more than they believe the true facts.

Pierre mentions “All graphics cropped from Lüning’s presentation with permission.” so I won’t copy them here.

Distinct solar imprint on climate What’s more worrisome,

Schlüchter’s findings show that cold periods can strike very rapidly. Near the edge of Mont Miné Glacier his team found huge tree trunks and discovered that they all had died in just a single year. The scientists were stunned.

“The year of death could be determined to be exactly 8195 years before present. The oxygen isotopes in the Greenland ice show there was a marked cooling around 8200.”

That finding, Schlüchter states, confirmed that the sun is the main driver in climate change.

Here’s a nice confirmation of Harald Yndestad’s work on Long term lunar tides in the north Atlantic. He found a 74 yr cycle.

A 70-80 year peridiocity identified from tree ring temperatures AD 550 – 1980 in Northern Scandinavia

  • a Finnish Meteorological Institute, P.O. Box 503, FI – 00101 Helsinki, FINLAND
  • b Department of Geosciences and Geography, P.O. Box 64, FI – 00014 University of Helsinki FINLAND

Abstract

The classical Maximum Density data of 65 Torneträsk trees from years 441-1980 AD are studied in millennial, centennial and volcanic scales. The millennial scale is analyzed applying a specific filtering method. In that scale, the climate is cool after 1200-1400 AD. This more or less steady period is suggested to be due to volcanic episodes, which reduced the northward heat transport in the North Atlantic. The century scale variation, on the other hand, is suggested to be due to internal oscillations in sea surface temperature (SST) and to be connected to variations in the Arctic sea ice. Specifically, these oscillations have caused an additional warming and cooling trend in Northern Fennoscandian temperatures before and after 1930’s, respectively.

Variations in the temperature estimates are explained by the results for different temporal scales. All of them show local impacts leading to differences when compared with hemispheric estimates. The long-term estimate of the temperature as derived from the present Torneträsk data is found to be biased. The source of that is unknown.
