It makes intuitive sense to use that most living things, us included, have a growth spurt when they're young, and then slow down or stop. But in a new paper titled Rate of tree carbon accumulation increases continuously with tree size published in the prestigious scientific journal Nature, scientists explain how they've found that this doesn't apply to trees; in fact, the inverse is true. Older ones grow faster than younger ones. This is an important finding because it goes against a widely held belief that large trees are not as productive as small ones when it comes to taking CO2 out of the atmosphere.
The researchers looked at 403 tropical and temperate species of trees, and found that 97% of them were growing at increasingly faster rates as they aged.
Even trees that aren't growing taller keep getting wider and thus turn CO2 into wood at increasing rates.
The study was a collaboration between 38 scientists around the globe and was based on 673,046 individual trees using 80+ years of data. Now that's a broad sample!
Im not sure why this discovery is interesting.
Bigger entity's grow fast because they are bigger and absorb more nutrients. big whoop?
Our results resolve conflicting assumptions about the nature of tree growth, inform efforts to undertand and model forest carbon dynamics, and have additional implications for theories of resource allocation and plant senescence.

Well.. maybe I am an idiot and did not know this or had not thought about it before...
I just did not realise that as trees get older they grow faster. I thought it was like most things as you get older things slow down. That was what was new to me..
Shall I ask a MOD to delete it...?

I think they are referring to the fact that humans reach adulthood at which point they do not get taller or gain mass at anywhere near the rate they did when younger (unlike the trees). If you are referring to obesity, that is not the normal course of growth.
