Do you not think this is rather a kneejerk reaction? Is it as awful an
idea as injecting thousands of tons of silver dioxide or similar
materials into the stratosphere? An action which will influence the
global weather for a minimum of 4 years if done at the equator. Now that
is a truly awful idea. On the other hand, I would say that the
consequences of lighting forests are more predictable, and the idea is
scalable and can be stopped easily.
In any case perhaps with some adjustment the idea may have merit. How
about lighting desert plantations in marginal areas, not in pristine
forest where delicate flora and fauna exist. Solar power can recharge
batteries or lighting. Or extreme northern boreal forest, where few
other animal forest species exist in large numbers. In areas of low
radiation such a light boost may be just what it takes to increase
productivity.

"unintended (or uninformed) consequences" of this are horrifically
mind blowing.

Exploration of a novel geoengineering solution: lighting up
tropical forests at night
Xueyuan Gao, Shunlin Liang, Dongdong Wang, Yan Li, Bin He, Aolin Jia
Abstract.
Plants primarily conduct photosynthesis in the daytime, offering
an opportunity to increase photosynthesis and carbon sink by
providing light at night. We used a fully coupled Earth System
Model to quantify the carbon sequestration and climate effects of
a novel carbon removal proposal: lighting up tropical forests at
night via lamp networks above the forest canopy. Simulation
results show that additional light increased tropical forest
carbon sink by 10.4 ± 0.05 petagrams of carbon per year during a
16-year lighting experiment, resulting in a decrease in
atmospheric CO2 and suppression of global warming. In addition,
local temperature and precipitation increased. The energy
requirement for capturing one ton of carbon is lower than that of
Direct Air Carbon Capture. When the lighting experiment was
terminated, tropical forests started to release carbon slowly.
This study suggests that lighting up tropical forests at night
could be an emergency solution to climate change, and carbon
removal actions focused on enhancing ecosystem productivity by
altering environmental factors in the short term could induce
post-action CO2 outgassing.
