The Earth is Greener

Sprintcyclist is implying that the greening of the arctic is a good thing.

The greening of the arctic is evidence that temperatures in the arctic and antarctic are rising faster than the average temperature rise of the planet.

It's not a good portent because the greening will cause more heat to be absorbed from the sun which was previously reflected back into space by ice and snow.

Please don't thank me. Effusive fawning and obeisance of disciples, mendicants, and foot-kissers embarrass me.

Lee is evidently eager to win a contract for his stump-jump plough.

Off you go.

What if this 'extreme' and erratic climate change of very cold, very hot, very wet, very dry, etc. What if the climate is warping towards an outcome??

What if it manifests in a world where the Equator is a constant 30C degrees and both Poles are a constant 10C degrees... just like what the Saurians
enjoyed? Their hazy sky is our hazy polluted sky. Who knows, your planet is probably already being 'terraformed' from behind closed doors.

We would benefit from more CO2

The only working map in the link shows the predicted increase from 2081 to 2100.

A significant increase in green cover in boreal and Arctic regions was observed in the new maps, which researchers attributed to rising temperatures. For example, Svalbard in the high-Arctic saw a 30 per cent increase in greenness, according to Rama Nemani of NASA’s Ames Research Center and co-author of review paper. The green cover grew with an increase in mean summer temperature from to 4.7° Celsius from 2.9° Celsius (37.2° to 40.5° Fahrenheit) between 1986 and 2015.

Oh dear,
So the increase in greenness is mostly because of global warming in the higher latitudes
Thanks for providing evidence that climate change is real

Ah no thats not the case.
Like most things there will be advantages and disadvantages to our increasing levels of CO₂
The disadvantages however overwhelmingly outway the advantages with CO₂. Especially considering how much our modern economies rely on a stable climate
