In a nutshell: if this is a permanent trend, not a anomaly, it is likely that flooding and disruptive weather events will ensue sooner and at greater frequency than in other, more conservative climate models. Arctic wildlife, such as polar bears and seals, are likely to suffer to the point of severe endangerment.
Although couched in the sensational language of media, Forbes - not exactly an eco-warrior tree hugging zine - has it about right: https://www.forbes.com/sites/trevornace/2018/02/27/collapse-polar-vortex-arctic-melting-winter/#6cf58ac339cd
To keep things relevant to the NPA theory...in 2013 when I experienced Typhoon Haiyan in the Philippines and thereafter enjoyed six weeks with little electricity, I realized that climate events would hit poorer, equatorial countries hard, and that it would likely be the issue of my generation and the next. Sanguine, non-perfectionist populations in less developed nations dependent on agriculture will bear the brunt. Manila is already growing used to being in a state of perpetual mild flooding - more big cities will be in the same waterlogged boat in years to come. For many, the sudden rise of filthy water around one's ankles will soon be as mundane an event as a power outage, but with direr consequences for public health.
Unfortunately for us comfortable Westerners, the raw resources of these nations support our lifestyles and our appetites. Also the West itself isn't immune; rich, low-lying nations such as The Netherlands will find it difficult to engineer against sea level rises, as will US states like Florida and Louisiana. The USA's coastlines are vulnerable, and inland the potential for the return of the dust bowl - yes, that anachronism of Depression-era America - looks likelier by the year. Food prices will rise faster; present yearly grocery price increases of circa 5-8% will become 10%, then 15%...
Not to say things are entirely bleak from an anthropocentric perspective: the problem will probably be overcome, but the damage will be greater owing to political inertia and general ignorance. A massive, global scale effort - a sort of 'Green New Deal' - should already be underway, but isn't. Most members of our species aren't thinking logically, non-selfishly, or for the long game - but it was ever thus.
