The claim is sorta True however the articles title is misleading making it seem like its a bigger issue than it really is, its true to the extent that its an issue like this quote from the article linked Quote
“We shouldn’t rely on natural forests to do the job. We really, really have to tackle the big issue: fossil fuel emissions across all sectors,” says Prof Pierre Friedlingstein of Exeter University, who oversees the annual Global Carbon Budget calculations.”
With the title “Trees and land absorbed almost no CO2 last year” it gives off the vibe like if all trees or plants have stopped when in reality its exaggerated probably for attention but the article does prove itself with info that is valid and actually correct for example the same article states this Quote
“A paper published in July found that while the total amount of carbon absorbed by forests between 1990 and 2019 was steady, it varied substantially by region. The boreal forests – home to about a third of all carbon found on land, which stretch across Russia, Scandinavia, Canada and Alaska – have seen a sharp fall in the amount of carbon they absorb, down more than a third due to climate crisis-related beetle outbreaks, fire and clearing for timber.”
Good to say that this is true but misleading in my thoughts
