Found this bit of info re declining O2 levels

Direct observations since 1989 confirm that the atmospheric O2 abundance has been decreasing steadily year by year (Keeling and Manning, 2014). The O2 loss is the flip side of the CO2 buildup from fossil-fuel burning, and is expected to continue throughout the fossil-fuel era. The CO2 buildup is a major environmental concern, with consequences for global climate via the “greenhouse effect,” for land plants via “CO2 fertilization,” and for marine organisms via “ocean acidification” (Ciais et al., 2013). In comparison to the CO2 buildup, the O2 loss is very small in relative terms. CO2 has now risen from a preindustrial level of ∼277 ppm to a level of 410 ppm in year 2020 (Friedlingstein et al., 2020). The measured O2 loss has been of comparable magnitude in moles, but this dwarfed by the massive atmospheric store of O2, which comprises 21% of air. Still, the fact that O2 is measurably in decline raises concerns. Considering that O2 is essential for aerobic life, how sure are we that the continuing O2 decline won’t eventually have significant impacts?

We are aware of two prior reviews of this topic. The first, by Broecker (1970), makes a compelling case that the projected future O2 changes would be very small and likely insignificant. The second, by Martin et al. (2017), uses projections of much larger future O2 loss based on a parabolic model of Livina et al. (2015). Martin et al. (2017) systematically considered the major factors determining the potential impact of atmospheric oxygen (O2) depletion on human survival. They discussed the different time domains of effects of hypoxia, from acute responses, such as increased breathing and circulation, to longer-term physiological and cellular

What has the concentration of 02 got to do with anything, there is no such thing, even if you mean O2 which is dioxygen molecule, what even it got to do with the supposed climate change.

Atmospheric 02 is decreasing. Ocean 02 levels are also falling due to rising ocean temperatures as a result of anthropogenic climate change.

The simplest means to reduce CO2 is to reforest the masses of land that has been cleared.
Australia has unimaginable amount of water beneath the surface.
Australia has vast areas of fertile land, the lack of water prevents sustainable growth.
Instead of wasting the trillions of $'s on a worthless cause bring water to the land.
Given time the eco system will change and these arid lands will benefit from increased annual rainfall.
Can anyone explain why we have rain forests on the northern Queensland areas when just across the paddock in Northern Territory forest is almost non existent.
Cyclones/monsoons dump a massive amount of rainfall on both areas, but the QLD forests/jungles retain more water promoting more growth because of the forest canopy reducing evaporation.
Plant more trees!

We can't help but remember the push to remove plastic bag from the environment.
The major stores succeeded, we now have biodegradable bags to carry home our groceries.
What an absolute farce!
You now go to Woolies and a percentage of their goods are now in Plastic containers almost requiring tin snips to open. (Especially meat section)
Contacted them and they replied the plastic was biodegradable and not a risk to the environment.
I decided to carry out an experiment placing some original plastic bags and the new plastic containers out in the sun. (January 2021) today the bags have completely disintegrated and the thick containers have only just changed colour.
Absolute joke, getting rid of plastics to save environment.

your a keyboard troll planetcare, you can't tell the difference between a numenrc 0 and an Alpha O there is NO atmospheric (numeric) 02 and NO ocean (numeric) 02 there may be some (Alpha) O2 but it is mostly just O = oxygen whereas O2 = dioxygen and your idiotic numeric 02 = 02

What are you going on about! OK 02 should have been O2 so what! What is a numenrc 0? You can't even spell it seems! The pot calling the kettle black! The key point and message is that mans activities are changing the climate due primarily to rising atmospheric levels of C02 from the burning of fossil fuels.

Gents, could we please not keep having a go at each other over climate change. Its not only the atmospheric levels of CO2 rising in our atmosphere, but my temperature/blood pressure listening to you guys quarrelling amongst yourselves, as to who's more in the right than wrong Shocked

From what's been discussed by the worlds leaders on climate change so far, some may think we can all just sit back on this a little more longer & over time things will sort them selves out.
Problem is, 20 odd years ago or so, this talk on climate change might have been nothing but talk in the wind, but in todays times/now, the worlds climate is showing us different & it certainly don't look good.
Temperatures are slowly rising, with climatic seasons around the world, not steady but all over the place.
If man don't start listening to the first early warnings of what's been happening round the world (whether/climate wise) & start to make changes for the better & make them quick, I fear there will be a heavy toll for all to pay.
So could we please stop with the condemnation of one another & continue discussion in a more positive manner.

The world is experiencing "season change", here we are in mid November and still have the doona on the bed.
Have it etched in my memory, today back in 1990 (yes 30+ years ago) snow fell on the Porongorups, WA.
We were camping at Black flag (just North of Kalgoorlie) and we drove around in our vehicle with the heater on to try and keep warm?
If you go through records from when they were first recorded there were periods of extreme heat.
When you have 3 billion+ inhabitants in the world who are virtually removed from all this "climate change" hype, mankind (OOPS personkind) nothing will change in this twisted world.
Australia is accused of being one of the worlds greatest polluters (25 million population) with a great proportion uninhabited, a few kangaroos and camels farting in the outback. It's a joke!
The only world threat is the US (war mongers) starting a conflict that becomes nuclear. Weapons manufacturing, the most profitable business of all time.
Was it a trillion dollars worth of military equipment the yanks left behind after another futile war.

Nightjar, it matters not what name we put to it (climate change, season change or weather change) it is a change none the less for the worse & we're all contributing to it. What concerns man here is that weather events are happening far more often around the world, with far more devastating effects to ones environment/existence, than in the last 30 or 40 odd years or so.
Now I ain't no doctor nor scientist when it comes to giving advise on such matters, for it is in those sciences & medicines we all rely on in our time of need.
We as individual human beings can believe in what ever we wish to believe in, but lets not allow our beliefs blind us from what is actually happening/taking place around the world & the requirements needed in order to tackle, minimise, or stop such events from Occurring.
3 billion people removed from the effects of climate change? I highly doubt it, for it is the same 3 billion that are currently paying the price of "season change" through ecological disasters, along with the rest of the worlds populations.
As for any accusations by foreign countries as to Australia/Australians being the worst poulters of the environment, we all know is not true, for the population numbers in Australia alone, tell us that the stats just don't add up to such.
As for war mongers as you put it, what exactly is new or changed? If it isn't this one war monger today, it will be another. All countries have & will go through their war mongering times & days. The greed for money & control of power will never change, for it is in mans nature to continue to seek it out & posses it.
Through the devastation & aftermath of war, man seeks peace & through many a year of peace, man starts to seek war again.
It took some time & no doubt to great expense, for both Russia & America to finally realise, that it were futile trying to control & make change for the people of Afghanistan, for just like themselves (USA & Russia), only the people of Afghanistan can make change in the ways of how they wish to live as a society, within their own country.
As for the Taliban, It matters not who or what comes into power in order to rule a nation, only in how they go about in ruling it.

Well Canberra weather average conditions have not changed since we moved here in 1980.
http://www.bom.gov.au/climate/current/month/act/summary.shtml

Some stats for 74-88.
http://www.bom.gov.au/climate/averages/tables/cw_070282.shtml

Nothing much has changed although it is a bit nippy this morning but nothing out of the ordinary. and our suburb has had roughly double the average rainfall for Nov...So what! Averages have highs and lows well above or below the mean.

And yeah there is a lot of water locked up as aquifers in the Great Artesian Basin.
About 65,000,000 G/ltr which is about 130,000 Sydney harbours.

Climate change like the Covid pandemic, does not exist. pale

Ok I tend to agree with most of the above except for the bit about the USA being a war monger threat to the world.
I reckon that label should go to China; Their military strength is growing very rapidly plus if the world keeps heading towards zero emissions by scrapping petrol and coal then we will be playing into China's hands while they continue to build and control coal powered electricity generation and you won't see them shutting down oil production, they need these things to power their military strength.
Right now there is nothing friendly about China and whenever another country does something that they (China Communist Gov) do not agree with they are quick to threaten that country with sanctions and other threats Watch out people you cannot afford to pussyfoot around China for fear of upsetting them. You have to show strength not weakness.
On the other hand a large majority of the worlds countries will be against China in a conflict and if China tries to take Taiwan by force then there might be a bit of a world scuffle. If America steps in to help Taiwan then we will be a obliged to do likewise.
