Despite the provocative title this seems well-intentioned. The scientific accuracy needs to be top-priority, these particular elements of the projections should be assessed and reevaluated if necessary.
It’s an eminently reasonable request, one that should be celebrated. I don’t know why it’s necessary to write thousands of words impugning the scientific integrity of climate science.
What is much scarier to me are possible effects of GHGs that could make any emissions path much worse. Methane levels seem to be increasing, which could make current projections obsolete very quickly.
