Processed Hemp sequesters CO2, it does not scrub it. Hemp is beneficial as a scrubber only during its vigorous growth pattern.
As to specific locations; Hemp grows everywhere and requires very little attention, until harvest time.
Ok, that’s my contribution of a potential remedial action that has an immediate effect in reducing CO2 emissions.
Not from growing Hemp.
Greenhouse Gas
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
I’m fully aware of the differences of sequestration and scrubbing. Why did you mention that?
And no, Germany’s problem is that the wind doesn’t blow and the sun doesn’t shine enough. Again why are you telling me what I’ve known for 50 years about GHGs?
The most important news I’ve heard on climate change was last week. A blurb on one of the news shows said that scientists have discovered evidence that the ocean “conveyor belt” is collapsing. The theory is well known but this is the first time I have heard that there is evidence that it is actually happening. I haven’t had time to chase this down. If it is true we are probably in for an ice age and possibly within the lifetime of some of of us.
This may be of interest.
Greenhouse gases are a hot topic (pun intended) when it comes to global warming. These gases absorb heat energy emitted from Earth’s surface and reradiate it back to the ground. In this way, they contribute to the greenhouse effect, which keeps the planet from losing all of its heat from the surface at night.
The concentrations of various greenhouse gases in the atmosphere determine how much heat is absorbed by the atmosphere and reradiated back to the surface. Human activities—especially fossil-fuel combustion since the Industrial Revolution—are responsible for steady increases in the concentration of greenhouse gases in the atmosphere. The five most significant gases are presented here.
Water vapor is the most potent of the greenhouse gases in Earth’s atmosphere, and it’s sort of a unique player among the greenhouse gases. The amount of water vapor in the atmosphere cannot, in general, be directly modified by human behavior—it’s set by air temperatures.
The warmer the surface, the greater the evaporation rate of water from the surface. As a result, increased evaporation leads to a greater concentration of water vapor in the lower atmosphere capable of absorbing infrared radiation and emitting it downward.
Of the greenhouse gases, carbon dioxide (CO2) is the most prominent. Sources of atmospheric CO2 include volcanoes, the combustion and decay of organic matter, respiration by aerobic (oxygen-using) organisms, and the burning of fossil fuels, clearing of land, and production of cement by humans.
These sources are balanced, on average, by a set of physical, chemical, or biological processes, called “sinks,” that tend to remove CO2 from the atmosphere. Plant life, which takes up CO2 during the process of photosynthesis, is an important natural sink. In the oceans, marine life can absorb dissolved CO2, and some marine organisms even use CO2 to build skeletons and other structures made of calcium carbonate (CaCO3).
Old news. We know all this
Maybe it’s time you need to be reminded.
Why do we need junior high wall posters?
And hemp generates electricity how?
Hemp isn’t actually the best thing either, because it is a weed, it can easily take over and choke out other plants, which are also necessary for the environment. IMHO, we need to go to solar and wind energy. Those two sources are perpetually renewing themselves and are an endless source of energy… unless the sun goes nova and supernova, but that will be a long while. Hemp isn’t perpetually renewing itself, unless it starts smothering other plants and then that behaviour will also damage the environment. Solar and wind is the best way to go.

Hemp is a cultured cash crop. It has commercial uses besides scrubbing CO2 while in the growth stage. It is not a renewable energy resource.
In the wild it may compete with other plants, but as a controlled cultured crop it is grown for three months, harvested and reseeded or rotated with another cash crop. such as alfalfa.
What crops can be rotated with hemp?
Hemp reconditions the soil, but it does have a large nitrogen uptake, and so does best when rotated with a nitrogen-fixing crop like alfalfa or legumes . Another important feature of hemp that makes it a good rotation crop is its strong root-ball and long taproot. Dec 31, 2018
Exactly and we should be using renewable energy, not a weed that can smoother other much needed plants, which could destroy the environment too. If we use solar, wind, and water, we’d be much better off, cash crop or not. To recommend hemp, is like encouraging the coal and oil industry . In the end, it does more harm than good. It would be like encouraging palm oil too, which has also done great harm to the environment and other animals’ nature habitat. Hemp is a very bad idea in the long run.
Apparently my posts aren’t big enough. You seem to have missed the entire presentation.
If you don’t read what I post, should I expect your are going to read plain links?
I have explained that Hemp is a CO2 scrubber, aside from having commercial value after it has been harvested.
But if you need further poster high messages, here is one that may surprise you.
Could hemp energy be the key to our environmental survival?
Hemp batteries and hemp as a fuel source may sound far fetched to an average consumer, but those who are aware of hemp know the potential. These technologies don’t need to be invented, but like hemp plastics, already exist and are waiting to be adopted by the market.
Robert Murray-Smith and Steve have a video from 2016, which shows how they built their hemp battery, and how it compares in performance to lithium batteries.
According to the tests they ran in 2016, Murray-Smith was able to find that hemp performed even better than Lithium batteries under stress. In 2019 they have already improved their process in hemp processing and preparation to make even superior batteries. They have improved output by 20% and found how to limit corrosion to the metal of the cell.

I am very aware of hemp. My respiratory system is keen on reminding me. Some people are allergic to that weed. Both my son and I are allergic to hemp and come to find out we aren’t the only ones in this world. That said, hemp will make things worse on the environment and various habitats. It will not make for a bio-green future, contrary to what hemp proponents say. It will be just like the Palm industry, as well as coal and oil.

I am sorry to hear that mriana. Are you talking about allergy to marijuana or hemp, like as in hemp rope?
Consider, everyone is allergic to CO2.
Exposure to CO2 can produce a variety of health effects. These may include headaches, dizziness, restlessness , a tingling or pins or needles feeling, difficulty breathing, sweating, tiredness, increased heart rate, elevated blood pressure, coma, asphyxia, and convulsions. Jun 3, 2021
Please note that I am not advocating Hemp as a source of energy (emitting CO2) but as a way to sequester (remove) atmospheric CO2.
I am no expert, tho’ I had my day in IT as an Oracle DBA. I’m just fiercely rational and reasonably well read. And I think hemp is a good idea for scrubbing and sequestration as long as it’s not grown on agricultural land. Anyone got a spare hundred million acres of ‘useless’ marginal irrigated land? When we’ve got 10 x as much electricity so we can desalinate all we need for irrigation and water the deserts under the PV platforms, we can mop up the CO2 with hemp.
