Need info

[Jessica Gurevitch]

Hello folks--

I am looking for references for the assertion that trees cannot be enough to stave off catastrophic climate change, and also, for the assertion that for forests to make enough of a difference in future temperatures, we would have to stop growing in crops and turn all cultivated land into forests. I know I've seen reference to these ideas, but it would be very useful to have citations. Thanks in advance.

There was a mention of Sierra Club here yesterday; this month's Sierra magazine has an editorial by the President of the SC warning about the moral hazard of CDR as something promoted by Exxon, etc. (and a scam) to justify continued use of fossil fuels, and that all we need are natural trees to solve these issues. As a Life Member of the Sierra Club, I want to write a rebuttal to that (really uninformed) assertion. Would that it were true!

Jessica

Hi Jessica,

These are the ones I always use, starting from this popular piece:

https://www.theverge.com/2020/1/31/21115862/davos-1-trillion-trees-controversy-world-economic-forum-campaign

Most of the fuss around the "1 trillion trees will save us” comes from this paper in Science: https://www.science.org/doi/10.1126/science.abc8905 (notice the erratum, and all the replies they got)

In particular the following rebuttal: https://www.science.org/doi/10.1126/science.aay7976 (this is the most important reference I would say)

See also the issue with indigenous land rights from the IPCC Land report: https://www.wri.org/insights/ipcc-calls-securing-community-land-rights-fight-climate-change 

Some more papers that then dealt with specific points of the original paper in 2019:

https://wires.onlinelibrary.wiley.com/doi/10.1002/wcc.729 (Framing “nature-based” solutions to climate change)

Sorry for the dump, I get asked this question so much I have material ready for it :)

Thanks, this is super helpful!

Hi Jessica,

Here’s a story that highlights a couple of recent studies that should be helpful - albeit depressing to read!

Thanks very much!

Hi Jessica,

Note also the other article in this month’s, Sierra magazine which explains we can’t just use trees \- https://www.sierraclub.org/sierra/2022-2-summer/feature/carry-the-zero-carbon-dioxide-removal

The Sierra Club’s ​Climate Resilience, Carbon Dioxide Removal, and Geoengineering Policy is worth a read - it’s 99 pages!  BTW, it says, "It is prudent to conduct research on geoengineering in case it is required as a desperate last resort emergency cooling strategy to head off climate catastrophe”.

Cheers,

Holly
