Amused that this tweet by a self-professed climate expert (with little identifiable natural science education) is getting so much traction. Given the claims by @ShellenbergerMD are so clearly consistent with what any well-informed climate scientist would tell you #bcpoli https://twitter.com/DoctorVive/status/1277571209337671680
Any informed observer knows The Amazon is net neutral for oxygen. On an annual basis it consumes approx the amount as it generates. Most global oxygen is produced in our oceans
The stats about natural disasters he cites? That would be the IPCC SREX

The information about emissions is rich countries decreasing?
That would be the most recent IPCC report

The line about land use decisions (and not climate change) being the number one driver of extinctions with direct human exploitation being the next highest cause. That would be the IPBES https://www.un.org/sustainabledevelopment/blog/2019/05/nature-decline-unprecedented-report/
The stat about fire behaviour since 2003? That would be NASA data https://earthobservatory.nasa.gov/images/90493/researchers-detect-a-global-drop-in-fires
The most frustrating past is that all this information is easily available with only cursory research. Yet it appears the information is so inflammatory that @Forbes apparently disappeared his column on the story and he had to write a book to explain it all.
Decided to do this as a thread for @ShellenbergerMD but buy the book anyways
1) Humans are not causing a “sixth mass extinction”
This is based on a disagreement as to whether the "sixth mass extinction is underway". A topic that is not settled therefore cannot be falsified

2) The Amazon is not “the lungs of the world”
This is true, the Amazon is net neutral for oxygen. The oceans are the lungs of the planet

3) Climate change is not making natural disasters worse
Current data from IPCC SREX says there is insufficient data to say yes or no. Some increases are observed some are decreasing. Increases in damages are due to exposure (more humans living in exposed areas)

4) Fires have declined 25% around the world since 2003

5) The amount of land we use for meat — humankind’s biggest use of land — has declined by an area nearly as large as Alaska

6) The build-up of wood fuel and more houses near forests, not climate change, explain why there are more, and more dangerous, fires in Australia and California

7) Carbon emissions are declining in most rich nations and have been declining in Britain, Germany, and France since the mid-1970s
The UK office provides a long baseline to show that it did indeed peak in 1973 https://uk-air.defra.gov.uk/assets/documents/reports/empire/naei/annreport/annrep99/chap2_2.html

8) Netherlands became rich not poor while adapting to life below sea level
This is based on the innovation that allowed the Dutch to achieve the goal. It increased their land mass and their national wealth.
This one is up for debate but is not readily falsifiable

9) We produce 25% more food than we need and food surpluses will continue to rise as the world gets hotter
https://time.com/4494776/5-simple-ways-to-cut-down-on-food-waste/
The argument for reduction in food is based on RCP 8.5 with the other models suggesting increases in Temperate regions will make up for equator

10) Habitat loss and the direct killing of wild animals are bigger threats to species than climate change
This is the conclusion of the latest IPBES report. Climate change is listed as the third tier risk after human land use and exploitation
