Solar scientists argue that it is the Sun (and also its various relationships to the Earth) that is the primary driver:
As we've discussed before: before the industrial revolution, and even before the rise of human civilization, the climate was always changing. Fossil fuel consumption was not a factor in those climate change processes, so something else must have been the driving factor. Solar insolation changes, volcanic activity, meteor impacts, and dust storms caused by low CO2 may all have been contributing causes at one time or another. In some cases CO2 levels could lead the process, in other cases CO2 levels might lag other changes.
None of this has anything to do with the question of whether industrial civilization and its high rate of fossil fuel consumption, could currently be driving an episode of abrupt climate change.
Ruptly said:'Mini Ice Age' could hit Earth
What an odd little clip. The narrator seems completely oblivious to the industrial CO2 and MMGW issue, treating solar insolation as if it were the only variable in play. And the cinematography at 0:12 and 1:02 indicates that this producer has something besides climate science on his mind.
Here's the press release for the original Russian study that inspired the video, with another glamor shot of Dr. Popova.

Dr Helen Popova responds cautiously, while speaking about the human influence on climate.
“There is no strong evidence, that global warming is caused by human activity. The study of deuterium in the Antarctic showed that there were five global warmings and four Ice Ages for the past 400 thousand years. People first appeared on the Earth about 60 thousand years ago. However, even if human activities influence the climate, we can say, that the Sun with the new minimum gives humanity more time or a second chance to reduce their industrial emissions and to prepare, when the Sun will return to normal activity”, Dr Helen Popova summarised.
So Popova thinks that the solar minimum might more or less cancel out the effects of MMGW, which she disputes anyhow on the basis that there's "no strong evidence".
