I agree with your assessment of this series. In terms of the wealth of ideas its writers brought to bear, the work of Philip K. Dick came to mind, though others have compared it to "Black Mirror." I found the speech of the whale (in the voice of Meryl Streep) in the second episode most poignant of all.
"Keep on buying iPhones and watching our show guys, we promise we can make a difference if we think happy thoughts!" The show offers no solution or call to action. What it does show is that human greed will continue us on this path. Unless the megacorps that are financing this show are dismantled, strange how they never address that in their extrapolations isn't it?
In the last episode of the series, the uncomfortable truth is pointed out that guilt for our predicament is shared between the corporations that provide environmentally damaging products and services and the members of the public who demand said products and services. In any case, more than 91% of the heat produced by the burning of fossil fuels is absorbed by the world's oceans, so even if we stopped all carbon emissions immediately, the global temperature trajectory would still continue upward over the next several centuries, eventually leveling off at around 10°C (18°F)-passing through 6.7°C (12°F) in 100 years (c. 2125).
