There is something fishy about the Australian birth number graph.
Just looking at it, it looks like a registration lag issue. That the graph was compiled before all the numbers were added to the database.
Statistista sais the birth numbers for Australia were the highest in the last decade in 2021. at about 315.000.

During Covid I had a long stint of trying to figure this stuff out myself, as the common description of the “greenhouse effect” doesn’t add up.
After a lot of reading I realized some things:
1. A CO2 molecule that absorbs an IR photon will in the vast majority of cases loose the aquired vibration energy in a collision with another air molecule, and not emit a new photon. So the animation with a CO2 molecule getting “hit” by a photon from the ground and then reemitting it in a random direction is garbage.
2. A CO2 molecule that hits another molecule may end up in one of the vibration states that can release a IR photon. This happens all the time and cause a gas with a CO2 component to emit IR photons. The amount of photons emited is bases only on the temerature of the gas and can be calcluated based on Plancks equation.
3. These photons will of cause be absorbed by the CO2 some distance off. The only IR radiation in the CO2 absorbtion band that reaches space are the photons generated in the uppermost parts of the atmosphere, where the amount of CO2 above is small enough for the photons to actually escape.
So now we come to the actual and real “greenhouse” theory, that the actual science, and not the popular simplifications, are based on:
As atmospheric CO2 levels increase the point in the atmosphere that has little enough CO2 above to allow photons to escape moves up. Because temperature decrease with altitude the gas temperature at this point will be lower for a higher CO2 concentration. Therefore fewer photons will be generated in the layer that actually transmit to space, and the energy flow will decrease, causing more heat to gather in the complete Earth system.
A bit hard to wrap you head around, but as far as I can figure out this is the actual theory used by atmospheric scientists.
One control question to ask about PCR tests is: If you have a large false positive percentage, how can some areas have positive rates close to 0?
In my area in Norway we are at about 0.5% positive tests of about 6000 a week at the moment.
I would say that indicates that if there are no viruses going around, then there will be no positive tests. Or else the test that is used in Norway works differently from what is used by other countries.
