Face to face conversation with Dane Wigington:

"If SRM were terminated for any reason, there is high confidence
that global surface temperatures would rise very rapidly to values consistent with the greenhouse gas forcing. CDR and
SRM methods carry side effects and long-term consequences on a global scale. {6.5, 7.7}"

One sentence before the IPCC-report pretends that SRM is not realized yet:
"Modelling indicates that SRM methods, if
realizable, have the potential to substantially offset a global temperature rise, but they would also modify the global
water cycle, and would not reduce ocean acidification."
