Human co2 emissions have nothing to do with climate change. kzbin.info/www/bejne/gYrXoIKDYr6ImMksi=7BJ4bCyXVVd8eX7D

[@freethinker4991]

Hi john it would be good if you reference were you get you info from For instance a "..study explores the environmental and economic implications of Internal Combustion Engine (ICE) vehicles, Hybrid Electric Vehicles (HEVs), Plug-in Hybrid Electric Vehicles (PHEVs), and Electric Vehicles (EVs)." The study, revealed that "..EVs exhibit the lowest CO and CO2 emissions of about 20 %, while HEVs and PHEVs demonstrate significant reductions compared to ICE vehicles. Note the EVs only produce higher NOx and N2O emissions of more than 70 %, because the study calculated the electricity was generated by fossil fuels when renewable electricity generation is used these higher NOx and N2O emissions are negated. The study was unable to take into account the approximately 20+% reduction in EV price, as such they still suggest the "..higher selling price and emission costs, EVs possess the lowest maintenance costs among the evaluated vehicles at only 0.00419 USD/km." The 20+% reduction in EV price since the study calls into question the suggestion that, "HEVs present the most balanced combination of selling price, emission cost, and maintenance cost, making them an appealing option for the market." www.sciencedirect.com/science/article/pii/S1110016823009055 Further reduction in EVs manufacturing cost are expected in coming years which will soon make them cheaper to produce then ICE, HEVs,and PHEVs due to the cost of the engine and with Renewables now comprising 39.4 per cent of Australia's total generation in 2023, an increase of 9.7 per cent in a single year. EV will reduce higher NOx and N2O emissions as they not longer rely electricity generated by fossil fuels. This will help in reducing the "estimated 5.13 million (3.63 to 6.32) excess deaths per year globally are attributable to ambient air pollution from fossil fuel" www.hsph.harvard.edu/c-change/news/fossil-fuel-air-pollution-responsible-for-1-in-5-deaths-worldwide/

[@severpop8699]

Hi john it would be good if you redo this video. The fact that you know it well takes you to automatically asume that partially explaining it well wil make everybody understand it fully. Nope, not working like that, it only makes everybody else understand it wrong. So burning one Kg of fuel releases about 3 Kg of CO2, nice, and how many Kg of H2O? should I hazard to guess it is about 10, or 14Kg? Say 18 Kg to be near the truth? hence 3 Kg of CO2 is rather 20% of the total coming out the exhaust pipe, and maybe H2O is around 78% and let's allow some 2% for other poorly burnt elements per litre of fuel? And all this mix is only about 20% of total exhaust if we take into account the nitrogen gas which is some 78% because inert and does not take part in the burning process, just passes through like a lubricant of sorts. So how much is 20% of 20%? About 4%ish from the total mix, and about 16%ish is water, than 78% stays unchanged and we have some maybe other 2% of else... I doubt most viewers even thought of this at all, you certainly took it for granted that if you understood it, everybody else did. You'd be in for a big surprise, they did not even asked temselves this question, let alone try to solve it even as rudimentary as I did here.

Actually, also factually, CO2 is useful even in the industry. For starters greenhouses use an air mixture with higher CO2 concentration cause plants eat co2 ( for their combustion ) and the more they get the more they give put in crops. CO2 is also being used in its solid form ( dry ice ) in bars etc - the "smoking" ice etc you see - BUT ALSO is being used in something called Cloudseeding ( also known as PART of them chemtrails ) as another technique used rather than silver iodide.

Australia has the great fortune to have a very long total day east to west. It's for sure the case that with a small population like Oz and with it's geographic location/features there is no reason why you guys shouldn't have a fully renewable grid with a little nuclear/gas for load balancing. But you're going to have to build a chain of solar east to east and the grid to link that and add more wind on the south coast.

[@GizmoGTI]

problem is you drive mostly during the day, and charge overnight, at night using the gird, the grid runs on gas/coal. as more ev's come about the more it will drive up demand driving up the cost of energy. it's hw it's playing out in my head - i could be wrong though. i see the two charges at our local dan murphies in the evenings always occupied and the driver is sitting inside with lights on reading his book - friggen nuts

Why does it matter how much co2 we emit? Evan NASA has admitted that increased temperatures and Co2 levels has caused the greening of the planet over the last 100 years. In fact 15% greener since 2000, predominantly in semi arid areas, meaning deserts are shrinking. Co2 is plant food, more the better. We are still in a Co2 drought compared to past levels.

[@pavelslama5543]

Because there is only so much that the plants can absorb. Plus it changes the reflection properties of Earth when it comes to solar radiation, making Earth absorb more. Which sounds like fun during a cold winter night, but it also sounds much less fun during a hot summer day, and it sounds even less fun when you realize that it affects ocean currents, wrecking stuff like the Gulf stream, which just by itself is a critical component in NOT making Europe a frozen hellscape. So, it doesnt cause a literal global warming, but more like a global sh*tstorm of crazy-ass weather and extremes on both cold and hot side, which has the potential to devastate things such as agriculture, which humans kinda need. Forget all the additional expenses on A/C in some places, and heating in other places. Food´s gonna be an issue. And also drinkable water in some places (that didnt have that problem previously).

A better question is, what happens to that car emitted CO2. Since it is released at ground level and is heavier than air, I would imagine that it stays ground level and feeds vegetation, as opposed to volcanos that drive gasses 40000 plus feet into the air.

[@axeman2638]

@@57greyghost no, the tree line is due to temperature not co2

[@NZ-Road-Cam]

There is slightly more CO2 measured nearer the surface of the planet due to this being where most CO2 is produced, however CO2 molecules quickly mix with all the other gas molecules in the atmosphere (air) and due mainly to the force of diffusion (along with other lesser processes like air currents), will move to occupy the large expanse of our atmosphere. The more CO2 produced will uniformly add to the overall concentration of CO2 in the atmosphere at all altitudes up to around 80km (262,500 ft). Despite many people thinking that the heavier CO2 molecule will sink to the surface, it does not. This is because our planet does not have a stratified atmosphere with separate layers of gas determined by its molecular mass. If it did, our planet would have four main gas layers, the first being a thin layer of CO2 found only on the surface and low elevations of the planet. The approx. 1% of atmospheric Argon would make up the next gas layer, Oxygen being approx. 21% of the atmosphere would make up the third layer and the last & largest layer would be Nitrogen which makes up 78% of the atmosphere. This would of course be incompatible with complex life and ecosystems so thankfully all these gases mix together to create the air we breathe.

A sunny day in summer for me is up to 30 kWh produced, which is 120 miles. To get 10 miles a day, would be 2.5 kWh, which would be a figure expected on a typical cloudy day in winter.

Earth's first atmosphere was up to 50% CO2 and had practically ZERO O2. Almost all of that CO2 has been sequestered by photosynthesis into sugar (six carbons) which life burns instead of the petrol (8 carbons) automobiles burn. Life has been very successful at sequestering carbon, either depositing it as carbonaceous rocks or petrochemicals. So successful in fact that only 0.04% of the original CO2 remains in the atmosphere. At 0.015% CO2 plants cannot photosynthesize, so we are dangerously close to the extinction of complex lifeforms that depend on plants. The exact opposite is true, we should be emitting CO2 like crazy trying to increase CO2 to a healthy level so life can thrive. Why??? Because CO2 has nothing to do with the temperature of Earth.

CO2 in solution tends to outgas unless the water is frozen, and the warmer the water the faster it does so, hence atmospheric CO2 follows planetary warming NOT the other way around.

A coal fueled power station would have around 33% efficiency, a car engine 25%, after all of the conversion, the EV would still probably be slightly more efficient, however a 3,000 kg EV is not as efficient as a 750kg IC, and it makes more sense to use fossil for cars and nuke/solar/wind for stationary applications, instead of having to use batteries for transport.

We would need to plant more trees covering the entire landmass of Australia as a Forest to even try to keep up. That seems infeasible so we try to slow down the CO2 emissions. For legitimate use of CO2, it's hard to capture it from the air and would take a lot of energy just to do so, it is less emissions just to make more of it for where it needs to go, than to go down the path of capture.

Says nothing about the efficiency of CO2 as a greenhouse gas.....how much temp rise per .001% increase in CO2? In the last 100 years it has gone from .03% to .04%. Most of that increase is from natural sources. The mean global temp has not changed significantly. The original idea was from a bell jar where CO2 was introduced and infrared source increased temp slightly. That was a static environment and not applicable to the extremely dynamic atmosphere. And CO2 is used extensively in industry, there are numerous natural CO2 production wells, 3 in New Mexico. The main source of CO2 is the Earth itself, ice cores that reveal hundreds of thousands of years temperature always show increase in CO2 AFTER a rise in temp, the result of warming, not the cause. Human source is in the noise, trivial. You know its bool sheet because THEY never ever explain why CO2 is bad.

[@ricoman7981]

I think you mean “thousands of years of temperature always show an increase in CO2 AFTER a rise in temp”. Currently your remark says an increase in temp AFTER a rise in temp. Earth history by proxy shows temperature rises and falls before CO2 rises and falls. If there is a cause and effect relationship it is changes in temperature drives changes in CO2 with a lag period. I agree that an increase somewhere between 0.8 degrees and 1.2 degrees since the beginning of the Industrial Revolution is not hugely significant if you consider that any of the excess warming beyond natural interglacial warming and attributed to humans is likely front end loaded, ie saturated as per discussions by Prof William Happer and others. People are calling for curtailment of all oil, gas and coal production and usage but that is simply not going to happen worldwide. Currently oil, gas and coal continue to provide more than 80% of the world’s energy mix and will not drop below 50% for decades into the future, well beyond 2050 and perhaps into the 2100s.

Coal would be different. Depending on the type of coal, it most likely will be a non homogeneous mixture with varying proportion of ash and other inorganic material in it, in addition to the carbon content.

[@pavelslama5543]

Yeah, coal contains all kinds of weird stuff, starting with sulfur, and ending with various heavy metals.

[@Vincent_Sullivan]

I agree! The question is one of the percentage of carbon in the mass of the fuel. Methane (CH4) for example has 12 unit mass of Carbon and 4 unit mass of Hydrogen or 75% mass of Carbon which is a fairly light carbon loading. As the carbon chains get longer the percentage of mass of Carbon increases and the the material gets more viscous until it become a solid. Coal consists mostly of carbon, with some volatiles, and non combustibles (ash). Since it's carbon loading is high it would produce relatively more CO2 and relatively less H2O for a given mass of fuel (ignoring the non combustibles) than lighter hydrocarbon fuels.

[@peetsnort]

How many trees does it take to offset 1 kg of CO2? To summarise the various studies, it can be concluded that annual CO2 offsetting ranges from 21.77 kg CO2/tree to 31.5 kg CO2/tree.

[@joejoejoejoejoejoe4391]

Actually, the electrical side is surprising efficient, using a 3 ton EV instead of a 750kg IC, isn't. A small point however, the electrical side can just about cope at the "current" demand, the peek demand being between 4 and 6 o'clock, now if most of the population plug in the EVs to charge, at between 4 and 6 o'clock, there's no way the electrical side could cope.

[@ArthurBiltcliffe]

My point was this. ICE engines are seen as inefficient. They run at around 30%, but heavily dependant on size and load in everyday use. EV, however, are seen as efficient and clean. But......if you start with a standard steam generation plant, it runs something like this. The boiler is around 88% efficient, bigger is better, but the losses are mainly the nitrogen in air, which goes in cold and comes out hot. The steam turbine is around 40% efficient but that's at maximum efficiency load. Once you're off the peak condition, efficiency falls quickly. Electricity is generated at around 83%. 2% of that is lost as heat and wind age, the rest to power factor usually 0.85 lagging. There are power line losses, proportional to amperage squared. This is minimised be generating at stupid volts, around 124,000V, then transformed down stage by stage. Transformers lose some as well - we'll allow them 96%, but that's at max efficient load and 0.85 lagging power factor. The point is that there will be at least 3 stages of transformation. Now the sum starts to look like this. Boiler × turbine x line losses x transformer loss1 x transformer loss2 x transformer loss3 Which is 0.88 x 0.42 x 0.95 x 0.96 x 0.96 x 0.96 which is about 0.28, or 28% efficient at point of use. Remember I've been generous, that's all at maximum plant efficiency. It's not so much different from your ICE engine. So the EV is carbon free as you drive it, but it costs about 170% of ICE to create, and around the same carbon footprint to fuel up. So thete's no environmental halo there to be claimed. They only make sense charged at home from full renewables, if you ignore the depreciation, insurance, maintenance and repair.
