Our house is burning. Literally. The Amazon rain forest - the lungs which produces 20% of our planet’s oxygen - is on fire. It is an international crisis. Members of the G7 Summit, let's discuss this emergency first order in two days! #ActForTheAmazon pic.twitter.com/dogOJj9big— Emmanuel Macron (@EmmanuelMacron) August 22, 2019
The Amazon is often referred to as "the lungs of the planet." It's home to 10% of the world's species and creates 20% of our oxygen.— ABC News (@ABC) August 22, 2019
There have been more than 74,000 fires in the Amazon since January, a massive increase over last year. https://t.co/rYmRqBKUMI pic.twitter.com/zGDtr2OWKg
"You're talking about an area that's truly one of the greatest celebrations of life on this planet —that literally cleans our water, purifies our air. We gotta get worried." https://t.co/rYmRqBKUMI pic.twitter.com/L49OgVYeKQ— ABC News (@ABC) August 22, 2019
Satellite imagery shows extent of devastating fires in the Amazon rainforest in Brazil, which are up 84% from the same time period last year.— ABC News (@ABC) August 22, 2019
Experts call this year's expansive fire outbreaks "truly heart-wrenching." https://t.co/rNOsbXECOC pic.twitter.com/nGc6MacLmI

An inferno in the world's largest rainforest, two-thirds of which is in Brazil, threatens the ecosystem there and also affects the entire globe. https://t.co/FM9gYyvHMt pic.twitter.com/oUouc8yY0a
Brazil's Amazon rainforest is in flames, burning at the highest rate since 2013, when that nation's space research center first began tracking fires there https://t.co/aXfbVuMOpN pic.twitter.com/WDM7GyTtW6— CNN (@CNN) August 23, 2019
Brazilian troops have been deployed in an attempt to fight a record number of forest fires in the #Amazon.— Sky News (@SkyNews) August 25, 2019
20% of the world's oxygen is provided by the rainforest. And it's burning.

The Amazon produces 20% of the oxygen in the Earth's atmosphere. If we fail to combat climate change now, soon we won’t have clean air to breathe. We must take #ClimateActionNow. This is not a drill or a hoax. https://t.co/0YtRf1TgY5— Rep. Barbara Lee (@RepBarbaraLee) August 23, 2019
Brazil's President Bolsonaro must answer for this devastation. The Amazon creates over 20% of the world's oxygen and is home to one million Indigenous people.— Kamala Harris (@KamalaHarris) August 24, 2019
Any destruction affects us all. pic.twitter.com/rbdtuHMXJ9
Also, the forests are being replaced by pastures and croplands, which also do photosynthesis and produce similar amounts of oxygen.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
Despite the widespread claim, the Amazon doesn’t produce 20% of the world’s oxygen.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
It’s more like ~6%
Okay. The spike in Amazonian deforestation and fires is a huge problem — for climate, for biodiversity, for indigenous communities, and for the entire world.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
But one thing we don’t need to worry about is the world’s oxygen supply. pic.twitter.com/jAw7V2HpU8
It’s biologically and physically impossible for the Amazon to produce 20% of the world’s oxygen.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
Plus, those rainforests will be replaces with soybean fields and pastures that also do photosynthesis and produce oxygen at similar, or higher, rates.
This is not an issue.
And lets be generous and say the Amazon is about half the productivity of the planet’s tropical forests (it isn’t; it’s less), then we can say the Amazon produces no more than ~6% of the world’s oxygen. Probably less.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
And, this doesn’t even address oxygen *consumption* by living things — like animals and microbes.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
It turns out that the Amazon ecosystem consumes, on average, about as much oxygen as it produces. That’s true for most ecosystems.
Also, @airscottdenning reminds us that the levels of oxygen in the atmosphere are so large, the biosphere’s year to year impacts on atmospheric O2 levels is small. It would take many thousands of years to make a big change in it.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
It’s more controlled by long-term geology.
The tragedy unfolding in the Amazon is the sudden rise (after years of steady declines) of deforestation rates, which releases carbon (adding to climate change), wipes out habitats and biodiversity, changes local climates, and hurts people.— Dr. Jonathan Foley (@GlobalEcoGuy) August 23, 2019
Let’s focus on the real problems.
Does @LeoDiCaprio et al and all the rainforest burning hypers know much of the area has had above normal rainfall this year, or the oceans around S America are cooling, and much of S America normal to below temps? I didnt think so Once again shallow thought no looking at data pic.twitter.com/SGMybLaw9q— Joe Bastardi (@BigJoeBastardi) August 23, 2019
