I suspect that it probably says
nothing about attribution but does make the assumption that there is a rapid rise in atmospheric CO2 and that it is the basis of a serious, developing problem.

In summary, there is little new
about climate science in the report, and
nothing at all new
about attribution of past warming and extreme weather events to human activity, projections of future warming and its effects, or potential for catastrophic changes.
For example, because the mass balance argument says
nothing about absolute numbers or
attribution it may be that we are also — for example — destroying carbon - fixing plankton, reducing the breaking of waves and hence mechanical mixing with the upper ocean, releasing methane in the tundra which was previously held by acid rain and which can now be converted to CO2, or it may be we are just seeing a deep current, a tiny bit warmer than usual because of the MWP, heating deep ocean clathrate so that methanophage bacteria can devour it and give off CO2.
But the author may know
nothing about energy balance or transient climate sensitivity or the
attribution problem.
The latter would fit the accompanying example but, like the example itself, would say
nothing at all
about human
attribution; and while you can torture some sense into the former — «explicitly state that humans have had little impact on global warming» or perhaps «explicitly pooh - pooh the claimed scale of human inputs to global warming» — you'd leave the example out in the cold.
