What if I told you the Paris Agreement on climate change relies on technologies that scientists know DO NOT and WILL NOT WORK?

Carbon dioxide removal (CDR) systems like Carbon capture and storage (CCS) and Direct air capture (DAC) put more greenhouse gases into the air than they take out, and bioenergy with carbon capture and storage (BECCS) would push Earth over ecological limits. https://theecologist.org/2020/nov/13/carbon-dioxide-removal-sucks
'Beccs features in more than 80% of the IPCC pathways, which means it sits at the very centre of the Paris agreement – even though it is not mentioned in the text. But there is a growing consensus among scientists that Beccs won’t work.' http://web.archive.org/web/20200520081250/https://amp.theguardian.com/global-development-professionals-network/2017/jul/03/paris-climate-deal-wont-work-our-future-depends-degrowth
The technology has never been proven at scale, and there’s no way it will appear in time to save us. Even if it did, it would require that we create plantations equivalent to three times the size of India, which would eat up 1/3 of the planet’s arable land' http://web.archive.org/web/20200520081250/https://amp.theguardian.com/global-development-professionals-network/2017/jul/03/paris-climate-deal-wont-work-our-future-depends-degrowth
This would make it impossible for us to feed the world’s population. And transforming that much land into bio-energy monoculture would trigger ecosystem collapse that could be disastrous for all of us. http://web.archive.org/web/20200520081250/https://amp.theguardian.com/global-development-professionals-network/2017/jul/03/paris-climate-deal-wont-work-our-future-depends-degrowth
'While many scientists and climate change activists hailed December’s Paris agreement as a historic step forward for international efforts to limit global warming, the landmark accord rests on a highly dubious assumption...' https://www.technologyreview.com/2016/01/08/247100/the-dubious-promise-of-bioenergy-plus-carbon-capture/
'BECCS at scale would require 724 million arable hectares of Earth’s surface to be dedicated to bioenergy crops, approximately double the size of India. BECCS of such magnitude looks wildly improbable' https://www.forbes.com/sites/andystone/2018/10/29/negative-emissions-wont-rescue-us-from-climate-change/?sh=bae509863626
to avoid a 1.5°C global warming calamity without relying on fantasy, large-scale carbon sequestration, the global community would have to get to zero carbon emissions by 2026. https://www.vox.com/platform/amp/2016/10/4/13118594/2-degrees-no-more-fossil-fuels?__twitter_impression=true
