Wrong. Trees absorb CO2 and produces O2 during the day, but it absorbs O2 and produces CO2 at night, so they are about net neutral with their consumption/production.

User:
I heard that trees capture carbon through photosynthesis during the day, but actually release some CO2 again during the night. Is that right?

ChatGPT:

Yes, that's partially accurate. During the day, trees, like other plants, perform photosynthesis, a process where they absorb carbon dioxide (CO2) from the atmosphere and, using sunlight, water, and minerals, convert it into oxygen and glucose. This process helps remove CO2 from the air and produce oxygen.
However, at night, in the absence of sunlight, plants, including trees, undergo cellular respiration. During respiration, they consume oxygen and release some CO2. This means that they do release a small amount of CO2 during the night.
While the amount of CO2 released during respiration is generally less than the amount absorbed during photosynthesis, it's an important part of the overall carbon cycle in nature. Despite the nighttime release, trees overall act as a crucial part of carbon sequestration, helping to mitigate the effects of increased atmospheric CO2, especially during the day when they're actively photosynthesizing and absorbing CO2.

User:
Is there a rough average you can give me of how much carbon an average tree would capture during its lifetime?

ChatGPT:

The carbon capture of a tree throughout its lifetime varies significantly based on its species, environmental conditions, growth rate, and the duration of its life. However, a rough estimation based on general averages indicates that a single mature tree can absorb about 48 pounds (22 kilograms) of carbon dioxide annually. Over a 40-year lifespan, this could amount to roughly a ton of carbon dioxide.
This figure might differ depending on various factors. Larger, older trees might sequester more carbon, while smaller or faster-growing species might have different rates. Additionally, conditions such as sunlight, water availability, and local climate also play a role in the overall carbon sequestration of a tree.
It's important to note that while trees contribute significantly to carbon sequestration, they also release some of the captured carbon when they decompose or are burned, so their net impact on carbon in the atmosphere considers the entire lifecycle of the tree.

You should have seen the YouTube video of some influencer where he was being presented as a down to Earth, frugal but charitable crypto nerd who really only wants to save the world and help poor people.
No mention of expensive mansions and extravagant partying in that video. Unfortunately I can't find it. Maybe the creator deleted it.

My spidy-sense was really tingling when I saw that, that something seems off with this dude. Fascinating, in hindsight, that it was right. Should probably listen to it more.

That was the classiest /. response I have ever received, and I have been here a while.

Thanks. Pretty classy yourself for acknowledging such. :D

You know, this is the Internet, where everyone's an expert and cynicism and negativity run rampant because many people confuse that with wisdom.
I've been guilty of some of that myself sometimes.
And now with the social media algorithms unwittingly pushing everything that riles people up to the top, for the clicks, hasn't helped much either. It can be a pretty nasty place.

Lately I've tried to do better, and before posting some knee-jerk angry rant or go off on someone, consciously temper myself, remember that despite the anonymity I'm talking to a person, and be respectful as I would be in person.
My little contribution towards making the Internet a slightly better place, one post at a time.

Comment Huge water reservoirs (Score 1) 59

Is it so hard or expensive to dig underground and create some huge underground water reservoirs?
Or if space is not an issue, just build it above ground.
Through placement at strategic locations where rainwater tends to accumulate, these could be great buffers for wet and dry periods.

I know, the scale required is probably immense. But if we're able to build huge water damns, bridges that span oceans and orbital space stations, maybe we can also dig some really big holes underground?

I understand. No offense intended.
You just frequently hear that on average, foods in the US are much less regulated and therefore more heavily processed with more additives than in the EU. It wouldn't surprise me if being exposed to that over several years would then make food from other regions taste blander in comparison.

I like my European Fruit Loops just fine. They are a delicious treat I almost never indulge in, because despite probably having much less sugar than the US counterpart, it's still a lot of sugar and calories.
You just need to reset your over strained taste sensors, perhaps by avoiding sweet taste entirely, for a few weeks.

Comment Re:'Cause Nuclear Power's Just Too Green and Relia (Score 5, Informative) 189

No, actually there's a reason for this madness. Germany's plan has always been to get the EU to rely on PV/wind, instead of nukes. It's not something they only did for themselves, they pushed the anti-nuke legislation at EU level, with varying success (thankfully, those had a strong opponent in France). And the real reason for that is of course that PV/wind requires backing by gas for its intermittency, so to get the entire Europe addicted to natgas - which they'd be all too happy to resell from their buddy Putin through their Nord Streams (at a errrm... "resonable" provision of course, that they'd absolutely not yank up once everyone was committed, no sir!).

Nice theory. But wrong. Germany's phasing out of nuclear was a knee-jerk reaction by Merkel after the Fukushima disaster. Merkel's Christian Democrats party (CDU), normally very pro-nuclear, was loosing plenty of votes to the Green Party. They just lost the important state of Baden Wuerttemberg, which was normally a safe CDU harbor, to the Greens for the first time in history. Being scared of a Green wave sweeping the country due to rising concerns of climate change and now Fukushima (the Greens have been opposed to nuclear since forever), Merkel and the CDU leadership decided to deny this incident to the Greens by taking ownership of the nuclear phase out, and thereby giving themselves a green profile, which they realized would be increasingly important over the next decades.
