#3> “It is ironic that the very same carbon emissions responsible for harmful changes to climate are also fertilizing plant growth,”
It's not "ironic" at all. It's only sad (maybe not for most of HN readership) that taxpayers are coerced into funding various government-led bullshit "research" - from climate to Covid-19 and more.
"Skeptic" circles mentioned this effect of CO2 1-2 decades ago, but it was ignored so that globalist-climatist agenda can continue.

#4The key line for those who don't read the article:
"Scientists say that global greening since the early 1980s may have reduced global warming by as much as 0.2° to 0.25° Celsius (0.36° to 0.45° Fahrenheit). In other words, the world would be even warmer than it is if not for the surge in plant growth."
The surge in plant growth is a result of increased amount of CO2 in the air as a result of anthropogenic activity. Quirky systems we have on the planet.
Other key piece of the pie - we need to reduce CO2e emissions to ensure habitability of the planet. I.e. our effects >> global greening effects.

#5One thing not noted in the article is how the albedo reduction from greening in the arctic affects warming, ice melt, etc. It is good that greening has a negative feedback effect, but albedo reduction likely reduces that benefit in those regions.

They mention growing season. I wonder if growing seasons have been extended too.

Greenery vs snow, yes. But vs brown earth? No.
Is it also possible that plants can effectively slow down the heat transfer to permafrost, at least when that shade is sorely needed during atypical heat waves?

There is also a possibility of more vegetation in the arctic → more BVOC (biogenic volatile organic compounds) emissions from the vegetation → more aerosols → more clouds, which could increase the albedo (albedo as seen from space) and thus reduce warming.
But these interactions are not very well know currently.

#9With the realities of science denial, publishing such a paper is borderline irresponsible. Those who have an interest in keeping up burning carbon will point to papers like this ("NASA says!") as "evidence" that we can continue on our current path.

I find this comment to be the epitome of science denial.
