The clever thing about this study is that it was able to analyse NO2 levels on a suburban basis. "The researchers also confirmed that neighborhoods that added more gas-powered cars saw the expected rise in pollution. Finally, they replicated their results using updated data from ground-level monitors from 2012 to 2023. “We tested our analysis in many different ways, and the results consistently support our main finding,” Whilst improved emission standards feed into the overall results they do not account for local differences. "

Yes, diesel plus AdBlue still produces more NO2 than comparable petrol engines. The point of what I posted was that the introduction of EVs has made a measurable difference in NO2 pollution. I thought this was interesting....isnt it?

AdBlue is only used in diesel vehicles. The main source of NO2 is petrol vehicles. Replacing petrol vehicles that produce NO2 with EVs that don't is beneficial to public health. Yes, CO2 is a bigger problem, but NO2 is also a significant health problem, especially in cities. The article does discuss this. "While the shift to electric vehicles is largely aimed at curbing climate change in the future, it is also expected to improve air quality and benefit public health in the near term." My point was that reducing CO2 is not the only benefit of EVs "Nitrogen dioxide (NO2) primarily harms the respiratory system, causing airway inflammation, coughing, wheezing, and increased asthma attacks, especially in children, the elderly, and those with existing heart/lung conditions. Both short-term and long-term exposure can worsen asthma, increase susceptibility to infections like bronchitis, and potentially contribute to developing asthma, chronic obstructive pulmonary disease (COPD), and other cardiovascular/neurological issues. NO2 also forms secondary pollutants like ozone and fine particulate matter, which add to overall air pollution risks."

I guess it is lucky for you that you don't live in a country where you can be bailed up by thugs who demand you produce proof of citizenship.

Adoption of electric vehicles tied to real-world reductions in air pollution, study finds "Using satellite data, Keck School of Medicine of USC researchers reported the first statistically significant decrease in nitrogen dioxide linked to zero-emissions vehicles."

Yep, like the motor I installed on my inflatable kayak - serious engineering required😁

Generally, I favour speech being as free as possible. Obviously inciting someone to violent acts or impuning someones reputation with falsehoods needs some limits on it. I am not necessarily an enthusiastic supporter or detractor of the new bill. My point is that these are not new restrictions; they have been tweaked as far as I can see. It is hard to argue that all of a sudden, we are all going to be highly regulated. The things you could say are not really so different from before. There will always be controversial edge cases. "Is it likely to incite violence or not?" I would suggest that for most of us, we are unlikely to ever stray into that territory since we obviously haven't previously.

We already have laws that place some restrictions on speech. Free speech has never been absolute. These are things you could have problems with threaten people incite violence harass or intimidate defame others. These restrictions have been around for many years. Why are you not all nervous about these restrictions? Have you actually read any of the bill? The Bill would introduce a new aggravated offence for religious or other leaders who advocate or threaten force or violence against groups, members of groups, their close associates, or their property, in contravention of sections 80.2A to 80.2BE of the Criminal Code Act 1995. The offence applies if a person, in their capacity as a religious or other leader, advocates or threatens force or violence in the course of providing religious instruction, or religious or secular pastoral care.

Just wondering in what way it will curtail your speech. What is it you want to say but think you will no longer be able to say?

Because a small number of people do drive drunk. Random breath testing literally does save lives. If it is a choice between offending your overly delicate feelings or preventing a drunk driver from killing someone, I think most rational, well-adjusted people will accept the trade-off.

Jeez, you do seem to be overly sensitive. When you fly, and you go through airport security, are you upset because you think the security staff are accusing you of carrying weapons? Random breath testing is not just about catching an individual who is a danger on the road, but more importantly, it is a deterrent against attempting to drink and drive. There are already laws against what you can and can't say (defamation). Do you believe that this means "everyone is a suspect?" There are many things we are called upon to do to keep society running relatively smoothly. When I rent a car (or many other transactions), I am not offended by having to show my driver's license or ID. I don't believe I am presumed to be guilty of anything. When travelling overseas, whilst it is a slight burden, the customs officer may want to look inside my bag. I do not take this as some kind of personal attack or allegation. None of these examples makes me feel "guilty"

No thanks

I suspect the orange idiot will be gone soon

Yep, here is a clearer picture

The answer is 0

4 clock faces, but this does not help.

Here is an interesting question. Without searching the internet, can anyone guess how many times"X" appears on the clock face(s) of the Big Ben clock? (Big Ben is actually the name of the bell.)

My son has been in China for the last couple of weeks and has shared some interesting pictures. He did a tour of a nuclear facility that was almost completed in the 80s. This facility was not for nuclear power but for the production of nuclear weapons. Started in 1964, it was discontinued in 1984. https://en.wikipedia.org/wiki/816_Nuclear_Military_Plant

I was just reminded by an article about an event 50 years ago today. I was growing up in Adelaide, and I was 13 years old. The Dunstan government had just decriminalised homosexuality, being the first state to do so. A religious nutter who claimed to be a clairvoyant predicted that this would cause a tidal wave on this day at midday, and it would wipe out Adelaide. Although apparently some took it seriously, a few sold their houses and moved, it was mostly treated a little more lightheartedly. Some workers turned up to their jobs in flippers and floaties. I can remember "I survived the Adelaide tidal wave" T-shirts. The Premier, the colourful Don Dunstan, stood on a balcony at Glenelg saying if the tidal wave came, he would turn it back.

I am pretty satisfied with my bank. The bank is owned by the customers, and I get to vote on remuneration for the board and on other issues, such as a recent merger. The board and executive are not on enormous salaries like the big banks. My accounts have no fees at all because of the way I use them. It does not have many branches; however, if I did want to use cash, I could use any post office. Non-Executive Director Remuneration (2024) The total pool for all Non-Executive Directors' (NEDs) pay was $895,698 per annum, an increase of 2.75% subject to member approval. Individual NED compensation for that year was intended to be as follows: Base Remuneration (NED): $95,287 p.a. (up from $92,737). Committee Chairs: $114,344 p.a. (a 20% loading on base remuneration). Board Chair: $171,517 p.a. (an 80% loading on base remuneration). Executive Compensation As a mutual bank, Bank Australia's executive compensation structure and specific individual pay packets are not reported in the same way as the publicly listed "big four" Australian banks (CBA, NAB, Westpac, ANZ). Data from third-party sites suggests a wide range for various management roles within the bank, with an average salary for an Executive Manager role estimated around $207,111 per year based on user submissions. In contrast, CEOs of major ASX-listed banks have significantly higher total compensation packages, with figures for Matt Comyn (CBA) at $8.5 million and Andrew Irvine (NAB) at $5.62 million in 2025, which include substantial bonuses and stock options

My son's partner is Chinese, although now a New Zealander. We met her for the first time when they visited a couple of years ago. We cooked a meal together. She taught us how to make traditional Chinese veges and this great spicy mashed potato and we showed her how to cook kangaroo correctly. Being her first time in Australia, she was keen to pet a kangaroo and eat one.

Actually thinking about it and allowing for the nuances of translation, this does make sense. I believe that aged beef is a thing in our culture also beef with a lot of fat, such as wagyu. There is a little something lost in the translation, though.
