Every continent is at the lowest fertility rate it has ever been on so far. Besides Africa and Oceania all continents are below replacement fertility rate, and the two that are above replacement are still consistently on the decline. While there are cultures with a steady fertility rate, these are often below replacement and still decline after 2-3 decades to newest low.
South Korea managed to reach the lowest fertility rate at 0.72 and is still set for decline.
It is possible that for Humans the actual lowest low fertility rate might be pandas ( that is zero fertility rate ).
All realistic population projections have to account for the fact that lowest low fertility rate hasn't been reached so far.
So here are the realistic projections for global population and fertility:
1. Highest high - Fertility rates remain the same through the century as they are today. - 13.59 billion population in 2100 and rising.
2. Medium - Global population growth rate declines at a rate of 0.1% every 5 years. 10.13 billion population peak by 2069 before decline.
3. Low projection - Global population growth rate declines at a rate of 0.1% every 2-3 years. 9.05 billion population peak by 2046 followed by decline in global population.
Most likely scenario, global population peaks earlier than 2080 as projected by the UN, makes it no higher than 9.5 billion humans peak at most.

Also I have no idea where the fertility rate actually increased in the past two years to explain the increase in population growth over the past two years.
As per macrotrends the fertility rate is rising in every country which sounds, incorrect to say the least.

Nowhere, but a sub-replacement fertility is not synonymous with immediate population decline. There's something called "population momentum", countries with high TFR which have experienced a precipitous fall like Brazil are still experiencing population growth because in Brazil's case the largest generation was the one born in the 1980s (4 million births per year in the early 80s) and while currently only 2.5 million are being born (while 1.5 million die every year), it's still larger than the generation born in the 1940s and equal to that born in the 1950s, so Brazil's population will continue to grow until the late 2030s when deaths will surpass births. Same with Argentina, largest generation born in the early 2010s.
You can see the base of the pyramid is getting narrower but the total numbers are still growing.

I know but the population momentum shouldn't cause the population growth rate to increase but to only ensure the population keeps increasing at ever slower rates long after their fertility rate goes below replacement. ( 40 years after fertility rate goes below replacement the population should start going into decline ).
As per my understanding.

You're unbelievably r-slurred, genuinely just an absolute mong. Think for a little bit about population pyramid shapes.

Because he is r-slurred and talking to him is pointless.

But the global growth rate is not increasing, it's kind of stable because African countries are experiencing a reduction in child mortality, so more healthy babies are being born, but this year global growth rate will be only 0.91%, stable in comparison with the past few years.

As per the Worldpopulationreview link it did increase in the past two years.
