There is this picture making the rounds right now, supposedly showing the areas affected by rainforest fires in Brazil (and other countries) right now. Of course it looks very bad and I'm pretty sure it is. I am, however, curious how it compares to the norm, let's say same time of the year?

One of many stories talking about "record numbers of fires": A Record Number of Fires Are Currently Burning Across the Amazon Rainforest

    I like the question, but unfortunately we need a notable source claiming that the situation is normal or not normal. I'm not voting to close yet because I think we can improve this question. – DenisS Aug 23 at 15:28

    Forest fires that are "really bad" are just like storms. Much of today's media gives the implicit claim that global warming has created this bad situation. Some are explicit. So you could find the claim and ask "is this because of global warming", but the implicit and actually interesting claim there is that this event is abnormally bad. That someone chose to tag this climate-change illustrates the point. – fredsbend Aug 24 at 15:00

    "With the fire season in the Amazon approaching its midpoint, scientists using NASA satellites to track fire activity have confirmed an increase in the number and intensity of fires in the Brazilian Amazon in 2019, making it the most active fire year in that region since 2010." earthobservatory.nasa.gov/images/145498/… – liftarn Aug 26 at 7:02

I stumbled upon this article today. According to the article, the fires this year are 80% up as compared to the previous year, but only 7% above the 10-year average. The article ascribes the claim to Daniel Nepstad who holds a PhD in Forest Ecology and is the Executive Director of Earth Innovation Institute.

    10-year average seems like a poor comparator given that the last ten years have been abnormally hot on the global scale. How does that ten years compare to the decades before? – Jack Aidley Aug 27 at 9:29

    Unfortunately, this is the best I've got so far. I'm not accepting my answer hoping that someone else will arrive with a better source. – user622505 Aug 27 at 9:52

    @JackAidley I agree, the ten year average could be misleading if the climate is changing exponentially – PC Luddite Aug 27 at 13:06
  • Probably, this means it's been bad for quite a while, and now the problem finally gets acknowledged internationally which is a good thing. – Wouter Aug 29 at 18:44
