I subscribe to this channel even though I think the owner is more worried than he should be, because he is realistic about what could and should be done. I think it’s worthwhile to transition virtually all electrical generation to hydro and nuclear, and then see what parts of the energy sector could reasonably be converted to electricity or direct nuclear. Trains and ships, certainly. Small cars, probably, larger vehicles and trucks, probably never. Air travel and agriculture, in your dreams. The most frustrating thing to me is that many of the same people who insist that we must go to zero carbon also insist that the only way to do it is with solar and wind. It will never happen, but if it did, the human condition would take a serious nose dive.
It takes insane levels of education and discipline to run the military nuclear fleet. It's hard to envision commercial shipping being entrusted with that. One excellent use for solar and wind is creating artificial liquid fuels, though, since that doesn't have to happen at a particular time, and you can overbuild substantially. Grid power should obviously have transitioned to nuclear 60 years ago.
Everything about this planet is more miraculous than anything humans have ever imagined. Too bad we have simplified life to what makes money and our own selfish desires.

Too bad that there was no push back on some of the climate CO2 narrative, like the comment that CO2 resides in the atmosphere for centuries.

I appreciate the effort to assess risk by examining the past, but it’s important to remember that everything we understand about events millions of years ago is very murky, and to call any of those events “sudden” as we understand that word today is inappropriate. As far as being concerned about the ability of life to adapt to warming on the scale that is reasonable to project today, one need only ask whether life is more plentiful on Earth today in the tropics or in the arctic. We clearly have a lot of room for warming before any hint of a mass extinction.
"everything we understand about events millions of years ago is very murky" - you seem to want to spread some FUD. "to call any of those events “sudden” as we understand that word today is inappropriate." - it should be obvious from the context of the discussion that the use of "sudden" is in regards to geology. And btw, an asteroid impact qualifies as "sudden" in anyone's book. "one need only ask whether life is more plentiful on Earth today in the tropics or in the arctic. We clearly have a lot of room for warming before any hint of a mass extinction." - just... nope. That is a current meme that AGW-deniers are pushing, but evidence says just the reverse. First, it is insolation that is driving plant growth and plants in the tropics get much more light than at high latitudes. _Secondly,_ the hottest parts of the planet are not the tropics but the subtropical deserts, and in such environs life is more sparse. _Thirdly,_ it is the poleward expansion of said subtropical deserts which will be one of the big drivers of extinction. _Fourthly,_ you ignore that 70% of the surface of this planet is water. And ocean life is more abundant in the cooler waters than the warm waters, and hot sea surfaces lead to anoxic conditions, a disaster for all but anaerobic bacteria.
@@TheDanEdwards 1:04:10 "...it should be obvious from the context of the discussion that the use of "sudden" is in regards to geology." So, you agree that his conclusions near the end of the interview were inappropriate.
@@TheDanEdwardsGarbage. Most ocean life is along the coast lines, and in the "relatively" warmer waters (the coldest ocean waters are deep and at the poles), because that is where the sunlight and nutrients are. Cold upwellings, "upwelling" to shallow depths where there is sunlight being the key condition, does have one advantage in that it has much higher dissolved CO2 for plant life to grow and then attract and feed mobile fish life; but in the absence of sunlight there is essentially no life at the bottom of the "cold" oceans, away from the shallow relatively warmer seas. The coldest ocean water is "deep", it sinks because it is denser than warm water, and devoid of life, because there is no sunlight below about 200 m. The corals are a predominantly "hot" water species found mostly in the seas within the tropics. The 2022, 2023 Great Barrier Reef assessments indicating the greatest extent of coral since they have been measured - but apparently they are all on the verge of death! The greatest variety of land life is by far in the tropic zones, not the temperate zones. Yes, warmer water can dissolve less oxygen than cold water, but lake and ocean areas with low oxygen are largely a result of real pollutants being discharged such as sewage, and nitrogen and phosphorus based chemicals entering the waters, and initially promoting excessive plant/algae growth (more life not less), with the resulting biological and chemical reactions subsequently using up the oxygen in the water - in high school we used to understand this process as eutrophication, but now it is CO2 induced climate change. The attempt to control the weather by adjusting the 3% human CO2 emissions, versus 97% from nature, is a massive failure in all regards, and is only leading to more consumption via a massive increase in mining, mineral extraction and processing, and end of life waste generation and more pollution as we adopt technologies and approaches with greater impact on planet earth than the use of hydrocarbons which resulted in the saving of our forests, whales, all big mammals which were historically used for food and clothing. We now think cutting down forests in North America, refining into pellets, and shipping by diesel train and boat to the UK to be burnt to generate electricity while emitting far more CO2 than had they just stuck to burning coal, or cutting down forests in the tropics to grow palm oil as a source of biofuel and burning it while generating as much CO2 as naturally available hydrocarbons is a good idea. The climate activists and politicians are causing untold damage to the planet while improverishing billions.
@@TheDanEdwardsMy point is that we don’t know how sudden any of those climate transitions was. Given that our measuring stick has markings at least 1000 years apart, there’s no way to know if these past changes occurred more quickly or slowly than those we have seen in the past 200 years. And I don’t ignore a fundamental truth about the ration of land mass to water on Earth. I just don’t mention it because it hasn’t really changed. I’ve lived long enough to see countless predictions that things are “worse than we thought” fail to materialize. Here’s an offer for you. Make ten specific predictions about something that will occur in the next ten years. I’ll spot you five of them, but if at least five of these predictions don’t occur, you have to come back here and admit you were wrong. My only condition is that I have to disagree with your prediction. No fair offering something like, “a city somewhere in the world will report a record high temperature.”
You compare two stable states and come to the conclusion that there was less life on the ice ball Earth than, for example, in the Eocene. But that is not the situation we are in -> we are racing towards a new equilibrium. The faster the speed, the greater the demand for adaptability. Everything has its limits, my friend.
