The Amazon basin is 2.1 million square miles, the (informed) worry seems to be directed mostly at the almost virgin State of Amazonas where fires are in line with the highest recorded since 2003?, per the Global Fire Emissions Database in your link.

Isn't the problem that, yes, they're below average now (because we're not at the end of the year yet), but they shouldn't be so high at this time of the year, and the peak should come much later (I think August to October)? (I'm no expert on this!)

Don't get me wrong, I think it's shitty that because of history, the US and the UK (I'm from the UK) got a headstart and polluted all they wanted. But the fact of the matter is, we know far more about the climate now, and such pollution simply can't happen now. I'd really like to see Western countries providing more funding for economic development in other countries, contributing to more green technologies etc, since a lot of their/our gains were by chance that we could pollute all we wanted 200 years ago. And not abusing globalisation and shitting on countries that don't fall for "free trade" which turns them in to low wage workers whilst the West enjoys the fruits of their labour.

The thing is, when it comes to the environment, it affects everyone.

I am from Brazil

Amount of fire is... normal.

About november (remember Brazil is south hemisphere) the humid season starts and the fires stop (even if people WANT to set stuff on fire it doesn't work, my SO is from Amazon state, according to her family except those months where the fire is possible, it is normal for it to rain every single day, sometimes multiple times per day... my SO misses the rain so much that she often opens rainymood.com )

This is correct, dry season will occur in a few months.

Deforestation via slash and burn has been going on for years, but the rainforest isn't growing back at anywhere near the same rate(basically it's not growing back at all). Even if it is populism, what is wrong with finally taking action to curb that?

2004 and 2005 had a gigantic spike in deflorestation that is pulling the average up. So the data is a bit skewed.

Maybe more like a submarine aiming to clear a path for their own beef industry?

It’s obviously a reaction to recent fire “alarms” in media but the statistics doesn’t say that this is somehow natural or normal. It’s simply been just as bad for many years.

Then why is everyone blaming the current president?

The reason Finland is doing this is the same why you are being down-voted for posting scientific data: political agenda. Science mostly doesn't matter, only when it fits your favorite narrative.
