Your video said nothing about consensus. That there is a very strong consensus is indisputable.
Q) Dr Judith Curry states that the IPCC has no explanation for the increase of Antarctic ice.
A) Unfortunately, Antarctica has been losing ice for the last five years so her point has become moot. I understood the explanation for increasing ice mass prior to this was from increased precipitation due to warmer air and seas.
Q) Curry states that the IPCC has no explanation for sea level rise between 1920 and 1950 and that the rate then was as great as now.

I still don't see it. Global warming started about 1850. Sea level would have been rising from rising temperatures. Besides, sea level looks to have been rising slowly for the last 7-8,000 years.
Q) Curry states that the IPCC has no explanation for the warming that has taken place for the previous 200 years
A) The IPCC position is that AGW is responsible for essentially all global warming since the Industrial Revolution or from 1760 to 1840. Prior to the IR, the world was slowly getting colder. So I don't know what she's talking about.
Q) Curry states that 40% of all observed warming took place before 1950
A) By picking 1950, Curry is able to make use of the small spike that occurred there and the lack of cooling for almost 20 years thereafter. And, of course, she was only computing up to 2015. Currently, the global temperature would plot above the title text of this graph at +1.46C

Q) Curry states that the IPCC doesn't have an explanation for the flattening of the temperature curve since 2000.
A) It didn't. There was no hiatus. See Karl, Thomas R.; Arguez, Anthony; Huang, Boyin; Lawrimore, Jay H.; McMahon, James R.; Menne, Matthew J.; Peterson, Thomas C.; Vose, Russell S.; Zhang, Huai-Min (26 June 2015).

Q) Senator Ed Marky (D, Ma) begins speaking about current state of climate science and global temperatures and makes some comment about Curry believing god is causing something (?)
Mark Steyn interrupts and asks Markey (sitting at Sen Cory Booker's seat for some reason) if he is suggesting there is no natural variability
Steyn interrupts Sen Markey with "Do you know what the Little Ice Age was Senator?"
Steyn interrupts Sen Markey repeatedly about the weather at Plymouth Rock
Steyn interrupts with "What percentage of climate change is anthropogenic"?
A) Mark Steyn has no qualifications whatsoever to speak to the topic of global warming. Repeatedly interrupting a US senator speaking in committee was astounding (though senators have never had a problem interrupting their guests). Steyn said nothing of value.
Q) Curry, speaking about a survey of AMS members that asked if recent changes were natural or human caused. 52% said human-caused.
A) The AMS has consistently been an outlier among climate scientists. It perhaps should be taken into account that very few of its members possess advanced degrees or are actually research scientists. There are also studies that have found a much higher proportion of political conservatism among their membership and there is a strong correlation between political positions and positions on AGW. However, even back in 2015, when she made this statement, a majority accepted the consensus opinion on AGW. From Wikipedia's article on the Scientific Consensus on Climate Change, here is a more current statement of the AMS official position on global warming, emphases mine:
American Meteorological Society
The
American Meteorological Society (AMS) statement adopted by their council in 2012 concluded:
A 2016 survey found that two-thirds of AMS members think that all or most of climate change is caused by human activity.
How's that?
