Trees bulking up on excess carbon dioxide in atmosphere, scientists say

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.

“Forests are taking carbon out of the atmosphere at a rate of about 13 per cent of our gross emissions. While we’re putting billions of tons of carbon dioxide into the atmosphere, we’re actually taking much of it out just by letting our forests grow,” Brent Sohngen, co-author of the study, said in a statement.

Previous studies have shown that over the last five decades in the US, the per-hectare volume of wood in trees has increased.

However, it has been unclear whether this increase was primarily driven by forest management and their recovery from past land uses, such as agriculture, or other environmental factors such as elevated carbon dioxide, nitrogen deposition, or climate change.

Research has also shown that through a phenomenon called carbon fertilisation, plants use an influx of carbon dioxide from the atmosphere to increase their rate of photosynthesis – a process by which plants combine energy from the sun, water, and other nutrients to spur their growth.

“It’s well known that when you put a ton of carbon dioxide in the atmosphere, it doesn’t stay up there forever. A massive amount of it falls into the oceans, while the rest of it is taken up by trees and wetlands and those kinds of areas,” Dr Sohngen explained.

    No problem. The EU will increase the burning of wood as that doesn’t emit CO2. Also tropical forests will be cut down (or slashed & burnt) so the peasants can grow biofuels.

    Just more waffle: what gets me is ALL the Burn of Trash – OUTDOORS. So much timber products is wasted to the planet / environment by bonfires & slash & Burn – but as we were told in Geography, many zero point nine nine moons ago, that the developing Nations slash & burn to release the Minerals as Ash ( Potash) for adding fertility to the tropical leached soils. Conifers also cause leaching from the acidity provided by the decomposing Needles in the heavy rainfall areas …. and so on.
    Poor people: you want heat? Collect & Burn ALL scrap wood / fallen timber. It’ll tidy the forest floors as well as the countryside. Less soil covering fuel for the next forest fire too.

    But the wood will not be as nutritious. /sarc

    C’mon, man! Every climate scientist knows that tree rings get bigger only from global warming. Pay no attention to CO2 concentration, or even precipitation.

    When you are a climate scientist, you can have your proxy, and eat it, too.

    Essentially the same conclusion that Dr Sherwood Idso came to in the 1990s – his famous pine trees photo composite here:

    For which it was insinuated that his conclusion was disinformation paid for by the coal industry:
