Here's a good link, will help many forum members here at a level they will understand

Whoa! There were humans in other countries well aware the world was not the centre of the universe and was not flat either.

You mean European humans that weren't the brightest in the world!

And agreed, the technology has improved a lot. Past discoveries were limited by the technology they had at the time.

Making assumptions because that's how it happened in the past is not a great way to disprove a point.

No one has ever claimed that climate is not changing, it has done so for around 4.5 billion of years. Man made climate change is another story.

It's pretty hard to believe anything that we can do will cause any major changes in climate.

The whole debate, if you want to call it that, just reminds me of the cigarette debacle.

The dart companies hired marketers with slogans and lawyers that picked apart academics over, dotting the i, crossing the T.
We also now have a Media which only skew one way which is distorting truth and promoting opinion.

I remember my 1st Boss. He mentioned that working in an environmental laboratory will change in the coming years and for me to adapt myself when these changes come. I found this great advice!
Unfortunately, these media companies, still want to live in the 50s and not adapt with change and they'll do anything in their powers to stop it.

There is no evidence that man-made carbon dioxide is the cause of a warming planet.

https://climate.nasa.gov/scientific-consensus/

t’s important to remember that scientists always focus on the evidence, not on opinions. Scientific evidence continues to show that human activities (primarily the human burning of fossil fuels) have warmed Earth’s surface and its ocean basins, which in turn have continued to impact Earth’s climate. This is based on over a century of scientific evidence forming the structural backbone of today's civilization.

NASA Global Climate Change presents the state of scientific knowledge about climate change while highlighting the role NASA plays in better understanding our home planet. This effort includes citing multiple peer-reviewed studies from research groups across the world,1 illustrating the accuracy and consensus of research results (in this case, the scientific consensus on climate change) consistent with NASA’s scientific research portfolio.

With that said, multiple studies published in peer-reviewed scientific journals1 show that climate-warming trends over the past century are extremely likely due to human activities. In addition, most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.

Problem is it's exactly like the EV threads. Those that accept that there could be truth in climate change and worth looking at vs those who definitely know (not open to any other suggestion) that climate change isn't true.

Most that look at the data for climate change suggest that they might be wrong but is it worth the risk.

If your habits make no change to the climate, how many here are going to sit in their garage and run their cars? Heck, plant a tree in your garage and "feed" the plant whilst you sit in the garage with the car running.

We are cutting down trees at an alarming rate and pumping more stuff into a closed system (the garage/planet) and expect it to make no difference. That is just illogical.

You might not die or pass out in the first few minutes of sitting in the garage with the engine running, doesn't mean the climate isn't changing in the garage.

I am not saying there is no truth to the claims but is there is a list available of the vehicles that manufacturers “dump” on to the Australian market because of our standards?

Also what are the like for like alternatives sold in other markets not available here that use less fuel and emit less.

As I have said I am not saying government and other sectors claims are not factual but surely if asked they could provide details of actual vehicles that are “dumped” here or not available here.

The Everest is offered with an Ecoboost engine in China. Much more efficient and less polluting than the 3.2/2.0 or V6 we get. But we don't see that motor here. Would be a much better drive with one of those over the garbage diesel one we get. At least give us the option.

I dont feel bad about my dinosaur burner. I dont drive often and my car is regoed and works. If i smashed the kays weekly and fuel costs became an issue, then maybe i would justify the $ to buy a more efficient car, but i owe no money towards my car and realistically, filling up once every 6 weeks, well no justification to spend heaps on a new car just to also not drive it much. Yes it wasn't my money (fuel card) but my old van I'd have to fill every 2 days. So 45L tank and got about 250kms from that so yeah that was a proper dinosaur burner. The 2.2L ranger i had after that, again work car, that would get about 700km to a tank of diesel but that had an 80 or 85L tank. Fairly similar to the triton i had after that with its 2.4L diesel. But that was working a service job out of a vehicle. In that case yes hybrid powersystems would work, but pure ev nope. In an emergency call out, imagine the customers response to you saying im on my way, just give me an extra 40 minutes as i need to charge the car to 80%... A 5 minute splash and dash you wouldn't even mention.

EV will cover 300 kms easily and you just plug in when you get home. Everyday you start with 300+kms available.

Im not taking a dig at ev's. Its just as a work car in a service role where you carry say 400kgs in the back and do not know how many kays you do in any given day and add towing lifts etc if needed, that could become a time hassle. Also, if its a company vehicle, charging at home will need to be metered and payed by the employer, and also an employer will not be happy paying an employee during the day for the time taken said the work ev need 40 minutes to charge due to kays. Also, i was 24/7 as in took the afterhours callouts. So do my 8-12 hours a day, but if a call came to me at say 2am, id chuck me pants on and jump in the car. Also my house was single phase and the mains were only 63A, so a 4.8kw hws, 3.6kw ac so realistically 10A slow charging would be the only option and i dunno, but im pretty sure that takes many hours to satisfy an ev. Thats why i think hybrid in that role would work a lot better.

63 amps single phase can run a 32 amp 7.4kw charger.

I carried well over 400kgs and tow my Race car which is 1500kgs without issues. Range still over 250 kms.

It can be done. If you leave the car at work, then it charges at work. If you bring it home, the modern apps will tell you exactly how much energy was used without an extra meter.

Sure, EV isn't for all use cases but your one works just fine with EVs. Just plug in when home and you're charging. You get about 50 kms/hr. Even if you wake at 2am, you'll be topped up.

Max demand with a 20A hws, 15A ac and gpos and lights for a house wont allow a 32A outlet on a 63a single phase installation legally. But anyhows, im not starting an argument. Realistically how many decent sized comercial ev's are on the market for under the 40k a pov pack triton is?

Unless it is charged solely from a solar source all you’re doing using an EV is changing where the pollution is coming from and in Australia that will be mostly from a very dirty coal burning power station. And then there all the social and environmental issues around the disposal and manufacture of the EV's batteries.

Its still cleaner from an emissions standpoint to charge an EV from a brown coal power plant than use diesel to move the wheels of a car.

I've done the maths in other threads. Even off pure coal (which the grid isn't anymore), you will reduce by half the emissions charging from coal vs fuel

Sea level rise in last 20,000 years, 2nd chart shows much larger rises than today 18,000 years ago to 8,000 years ago - particularly meltwater pulse 1A which was that 13,000 years ago approxmately...

https://www.e-education.psu.edu/earth107/node/1506

...which correlates with many of the worldwide end of the world myths

Most of that huge rise is the coming of the interglacial period, so that means many of our ancestors' settlements are about 400ft under water now. Again, so many legends of the seas swallowing the land whether that be off the Sunshine Coast or beyond Land's End or anywhere else. It is likely that the Laurentide ice sheet collapsed, for varying hypothesis why it did. My favourite is Randall Carlson's* one, imagine 100m deep of water moving at 160km/h over about 2 weeks over an enormous area - it left the scars on the NW US landscape you can still see today...

This doesn't take away from today's sea level rises, as the oceans expand (and locally, as land falls away in areas). The oceans are absorbing much of the CO2 and they are a huge system with many feedback loops.

At work the other day noticed that the installation I was working at near a housing estate, local voltage was at 252V, which is right on the upper spec of the standards (253V)

Must be from solar input from the housing estate, so there's a lot of excess energy being generated during the day that could go into people working from home EVs - there's a reason FIT is so low these days and its because energy during the day is basically worthless because there's shitloads of it and not overly much demand for it.

Its not a work vehicle, just like 70% of the Ford Rangers on the road in Melbourne

Back in 2006 when i bought my 1st multimeter our house was 1st from the pole mount tranny, it was 252v. Nothing wrong there. As 3000 says 230 these days, but its still typically 240. The forward at the front of the as3000 says somewhere that its an adaption of uk and irish standards or something.

Yep, nothing wrong there, but once it goes over this happens to your solar panels:



Which means during the peak solar window, your solar panels do absolutely nothing, because grid voltage is too high and the inverter cuts their output.

So I'd say having a bunch of people charging EVs in these areas which have peoples solar turning itself off all the time probably isn't going to strain the grid as supply is exceeding demand significantly on a suburb level.

So there's a comparator in the inverters that checks grid voltage?

Yep, local grid voltage goes too high and then it cuts the output of the solar panels,

The modern inverters ramp down output to try prevent it, but when she goes too high, off goes your solar setup.

Causes issues in some regions too if there's too much solar input to the grid, they'll restrict the amount of solar you can have on your house for a grid feed setup.

Usually I see 230-240V, saw 252V the other day early in the morning, and saw it again today but regional VIC instead of Melbourne suburbia.

Yep its within the standards so its fine, but its right on the edge of the upper limit.

As household solar stresses the grid, WA and South Australia will have the power to turn it off

From today, Western Australia will join South Australia in having the authority to turn off household solar systems at times when the electricity network is deemed to be under severe stress.

The regulations follow the runaway demand for rooftop solar in WA, where more than a third of residential and business customers on the state's main grid have an installation.

https://www.abc.net.au/news/2022-02-...load/100820354

Solar curtailment is emerging as a new challenge to overcome as Australia dashes for rooftop solar

Last year saw Australians install rooftop solar like never before, with 40% more installed in 2021 than in 2020. Solar system installations now make up 7% of the energy going into the national electricity grid.

Alongside the greater uptake of utility-scale solar (such as solar farms), this means cheaper and cleaner electricity is fast becoming a reality, putting the country on track to meet international climate targets.

But such a dramatic surge in solar output also poses challenges for Australia’s power system for two main reasons.

It results in increased periods of large oversupply when weather conditions favour solar energy. This leads to energy being wasted due to the need for solar curtailment – when a solar system shuts down or stops exporting energy to the grid to counter the energy spike.

https://theconversation.com/4-ways-t...-prices-173592

Off go your solar panels and you start importing energy from the grid, during the peak solar window on older setups - oops.

It effects some areas way more than others, depends on demand from the local area and the amount of people with solar panels on their houses.
