  • the geophysical need for a preventive carbon dioxide removal capacity of several hundred gigatonnes.

    I think it’s much more than that really, but yes, that is the only way to slam the brakes on things, and even with that some feedbacks might be already too far into play.

    Yet, technical, economic and sustainability considerations may limit the realization of carbon dioxide removal deployment at such scales

    And there is why even knowing what might have a chance doesn’t matter. This isn’t a “we should give up” viewpoint, but simply doing the math and physics. Because of what it takes energy-wise and logistics to remove that much carbon permanently from the cycle using zero emission energy sources (that we don’t have), it’s simply not going to happen. The “don’t give up” attitude isn’t to look for a fix, as even stopping all emissions right now won’t do that. It’s to realize that we have a harsh future ahead and to plan for just that, mitigate the damage as best we can and prepare for the worst. Anyone promising anything more than that is either ignorant of the facts, or is trying to sell you something while you’ll still buy.








  • Even fresh water has stuff dissolved in it, just in lesser amounts. Pure water isn’t a naturally occurring thing that lasts long. There are two components, water’s polarity which grabs things that are available, and how water in a large system that is getting energy isn’t going to stay still and “sit there”.

    Something interesting I learned the other day in following the recent launch of the Europa Clipper. One of the things they want to explore is how as Europa moves through the huge magnetic field of Jupiter it induces a magnetic field of its own. Why is this relevant? It’s one bit of evidence that the waters under the ice have salts dissolved in them, giving them conductivity to produce this field. So even there water is not “fresh”.


  • Fertile for what though? It’s true there is more greening in some places, but that doesn’t equate to a better world for humans and animals used to the previous climate. Plants are better at adapting to this, for now anyway.

    The fertility of the soil that I brought up isn’t even about CO2.

    Fun fact, with climate change you can get both cold and heat deaths. Warming of the Earth doesn’t mean just heat.

    Need to get outside of that echo chamber of climate denial. Oh right, you all have mostly moved on from denial to “it’s fine”. I forget the talking points sometimes. Harder to keep up with those than the facts.




  • Peak oil was about conventional oil. Had we not discovered other sources and methods for extraction then we likely would have run out. And running out isn’t accurate, it’s just that oil becomes harder to extract and thus too expensive for regular uses.

    There are many things that were predicted as a collapse factor that we then innovated solutions to break past those barriers. We’re too smart for our own good, because each time we find new ways to keep going we make things worse and get ourselves even more into a dead end. When we do “run out” of oil of any type, which will happen at the growing rate we use it up, will we be smart again and find replacements for all the things petroleum is used for (not just fuel)? One important one being fertilizer to make food grow in our otherwise barren soils. Fun fact: people need to eat to live. Most people in the world, especially the western world, exists and survive because of food thanks to oil.

    Lastly, we would have done so much better post-collapse if things had happened naturally with a smaller population and less damage to the environment. The higher you fall, the more it will hurt, and we’re damn high now compared to the mid/late 20th century.



  • Depends on if they’re signalling to land or not. Do they have hazards on or are already on descent? Since the responsible thing as a driver is to avoid any conflicts where I can, I’d give way being an unusual event, just like I’d let someone cut across lanes to get to an exit. They’re at fault and the anomaly, but if I can keep from being part of an accident I’ll do it. Trying to be dominant on the roadways at all costs is what causes many of the accidents.

    I’d just treat it as an aircraft that is making an emergency landing, and not try and hold my lane because I have the right of way. That won’t end well for anyone.
