Mann argued in an interview with Rolling Stone's Jeff Goodell that a "clean energy revolution and climate stabilization are achievable with current technology.

While Goodell said that much of the left had come to view carbon pricing as "basically a kind of neoliberal scheme that will enrich Wall Street and inevitably be corrupted by politics": Mann wrote that "really all of the solutions that we’re talking about are market economics", and also listed the Montreal Protocol in the past as a reason for optimism about carbon pricing.

However, the climatologist also stated that humanity may need to rethink the basic conceptual model for modern economies because "[there] is a larger conversation to be had about whether we can continue on this path of increasing resource extraction and consumption in a sustainable manner."

"It's YOUR Fault" is about the strategy to "keep the conversation around individual responsibility, not systemic change or corporate culpability", noting such things as Russian trolls' and bots' attacks on Hillary Clinton during the 2016 United States presidential election campaign, and bot-produced tweets to increase the level of denialism in online discourse about climate crisis.

In the same chapter, Mann argues that Russian interference with the aim of improving Donald Trump's chances could be summed up as born of the government of Russia's material interest in getting its own fossil fuels to the world market.

Mann advocates a price on carbon emissions as well as supply-side measures like a fracking ban and blocks on pipeline construction.

In chapter seven ("The Non-Solution Solution"), the author dismisses responses like natural gas, carbon capture, and geo-engineering as inadequate, and describes a number of notions of opponents of climate action (such as bridge fuels, clean coal, adaptation, and resilience) as "empty promises".
