Even though the warming trend of the past 100+ years cannot be explained solely by natural processes, models tell us that natural processes were the dominant influence on this warming trend.

Question
The long-term warming trend of global temperatures over the
past ~100+ years cannot be explained solely by natural processes
that force climate. Which one of the following statements
indicates what the temperature trend likely would have been - in
particular over the past 50 years - if natural processes alone
were forcing climate?
Fairly similar to what we have already experienced but with a few years
that were warmer and a few that would have been cooler than we have
actually experienced.
A slight warming effect on global climate but less than what we have
actually experienced
A slight cooling effect on global climate over the past 50 years.
No difference because natural processes that influence climate operate
on much longer time-scales than 50 years and thus can't effect climate
of the recent past.
Even though the warming trend of the past 100+ years cannot be
explained solely by natural processes, models tell us that natural
processes were the dominant influence on this warming trend.
