Edit: I know it shows the % increase in greenary. What I meant is the "greenary" shown in the map actually has almost no correlation with the greenery in the real world. Looking the map and expecting Rajastan to be a green area would be a bad idea.

#72Earlier quoted context omitted.
Clearly increased plant growth due to higher CO2 concentrations are not stopping CO2 concentrations from spiking precipitously right now, because it's still spiking precipitously. It's very small effect that would take enormous spans of time to make any significant difference. Also in order for those plants to grow faster and make a difference, there needs to be a significant amount of plants. So it's a marginal issu…
but TFA clearly says we haven't wiped out 90% of the plant biomass. It clearly says that there are more plants than there were 20 years ago, not less. CO2 concentrations are growing at <1% pa (year on year - there are large variations between northern hemisphere summer/winter), so an additional 2% absorbing effect from an increasing number of plants is not insignificant.

#73The map is kind of misleading. It shows Kerala one of the greenest States in India as as the least green while states like Rajastan where you can find hardly any greenary is marked as most green.

#74From what I understand, the increase in atmospheric carbon dioxide will have a massive greening effect on the Earth (plants love CO2). But it seems this fact is usually omitted so as not to complicate the intended message. I always found it ironic that the "eco" mode button in many cars is a leaf icon.
> it seems this fact is usually omitted so as not to complicate the intended message Any time a group starts altering the facts like this, it just shows that they value their 'message' above the truth, and they lose all credibility. Edit: Downvote = disagree, or people genuinely believe it's OK to lie to further your cause, I'm not sure what's more disturbing.

Doesn't the map show the trend? So it's not about how green it is but how mucher greener it's become over the last decade.

Activists often think it's okay to lie to advance their cause.

#78The title says trees but I think it really means “greenness” from a satillite view. Reading around the bottom, while India and China have done substantial tree planting programs, it sounds like a large chunk of this may be driven by unsustainable use of farm land. I’m not clear on how their increased farm usage corresponds to greenness and whether that matters. Would be curious if anyone can chime in.
From the abstract of the study[1]: > The greening in China is from forests (42%) and croplands (32%), but in India is mostly from croplands (82%) with minor contribution from forests (4.4%). I can't comment on the sequestration effects of farms, though, beyond my ken. [1] https://www.nature.com/articles/s41893-019-0220-7

#79Would it be possible to turn a desert region into a rain forest? For example if Nevada decided to plant trees in the dessert is it possible with enough irrigation or would all the trees just die?
