"Groundhog Decade: We’re Stuck In A Movie Where It’s Always the Hottest Decade On Record"
Somewhere on a Hollywood movie set for Groundhog Day, Part 2: Bill Murray wakes up to find he’s just lived through the hottest decade on record, just as he did in the 1990s, just as he did in the 1980s. And he keeps waking up in the hottest decade on record, until he gains the kind of maturity and wisdom that can only come from doing the same damn thing over and over and over again with no change in the result. Ah, if only life were like a movie.
Somewhere in PA: Punxsutawney Phil saw the shadow of unrestricted fossil-fuel pollution from Homo “sapiens” sapiens today. That means global warming for another six thousand weeks — and then some (see NOAA: Climate change “largely irreversible for 1000 years,” with permanent Dust Bowls in Southwest and around the globe).
If we keep listening to the siren song of delay, delay, delay from the anti-science, pro-pollution crowd and their enablers, then eventually people aren’t going to go through this elaborate charade of wondering whether some large rodent in Pennsylvania can predict the weather — the forecast will always be the same, “bloody hot”:
- M.I.T. doubles its 2095 warming projection to 10°F — with 866 ppm and Arctic warming of 20°F
- Hadley Center: “Catastrophic” 5-7°C warming by 2100 on current emissions path
- Our hellish future: Definitive NOAA-led report on U.S. climate impacts warns of scorching 9 to 11°F warming over most of inland U.S. by 2090 with Kansas above 90°F some 120 days a year — and that isn’t the worst case, it’s business as usual!

And, as noted, those scientific projections are simply business-as-usual warming.
“Projections of global warming relative to pre-industrial for the A1FI emissions scenario” — the one we’re currently on. “Dark shading shows the mean ±1 s.d. [standard deviation] for the tunings to 19 AR4 GCMs [IPCC Fourth Assessment General Circulation Models] and the light shading shows the change in the uncertainty range when … climate-carbon-cycle feedbacks … are included.”
Under the plausible worst-case scenario of high emissions, high carbon-cycle feedbacks, marmota monax and homo “sapiens” experience much worse by mid-century (see UK Met Office: Catastrophic climate change, 13-18°F over most of U.S. and 27°F in the Arctic, could happen in 50 years, but “we do have time to stop it if we cut greenhouse gas emissions soon”):
If we get anywhere near that outcome, I seriously doubt anybody is going to care about what Punxsutawney Phil thinks about whether it’s going to be an early spring or not.
- Science stunner — On our current emissions path, CO2 levels in 2100 will hit levels last seen when the Earth was 29°F (16°C) hotter: Paleoclimate data suggests CO2 “may have at least twice the effect on global temperatures than currently projected by computer models”
- Royal Society special issue details ‘hellish vision’ of 7°F (4°C) world — which we may face in the 2060s! “In such a 4°C world, the limits for human adaptation are likely to be exceeded in many parts of the world, while the limits for adaptation for natural systems would largely be exceeded throughout the world.”
