History does not always repeat itself … or does it?

As Auckland emerged from another lockdown, Diplosphere in Wellington hosted a talk comparing the 1920s to the 2020s. A heterodox levels of analysis was on show with adept panellists' views espousing the science of the climate, a sketch of macroeconomics of the past twelve months, thoughts on the resilience of our institutions as we face compounding shocks, the EU's perspective looking back and forward, a view from New Zealand business, and finally a more human and humane look: how manifestations of our love at weddings, funerals has changed in the pandemic era.

The discussion ebbed from the apocalyptic and flowed to the hopeful. We discussed big ideas but also learnt about facts and equations from economics 101 to climate, such as Y (expenditure)= C + I + G + (X – I), tax = love, life last year = 2020 + X (where X=wedding, funeral, illness, achievement, etc.), and the all important limit of 2 degrees of warming above pre-industrial levels. Speakers recognised similarities yet differences between the 1920s and our erstwhile decade. More than anything, it was a chance to stand back from the mayhem of information overload, and sketch out a big picture.

Nobody knows of course, how things will pan out. But to even canvas some of these points, to hear them uttered for the first time, makes one think and calibrate ones own actions and initiative. To learn that that above infectious diseases and debt crises, the World Economic Forum lists climate action failure, extreme weather, and human environmental damage as the top three risks to the global economy is sobering thought (Ref). We will carve up the talk into three parts, starting with the climate emergency.

The best-case scenario for our planet is 1-2 degree warming above pre-industrial levels by the end of the century.

What does this mean?

More extreme events but in some ways manageable. However, we have to do a lot of work to get there. Some panellists expressed grave concern in the resilience of our institutions to the whims of body politics to see us through. Because to get to 1-2 degrees (only) of warming, we need to do a lot of work.

We may laugh off planetary-level climate engineering (geo-engineering) at present, but before long policy makers may be needing to decide on radical ideas such as sunlight reflection through giant mirrors in space or artificially reflective clouds. Our best-case scenario is based upon a linear model of climate change, that is, increases in climate inputs like greenhouse gas levels cause proportional warming of the climate.

However, there are tipping points built into our climate system, catastrophic events that warming could unlock: release of gas trapped in the tundra, catastrophic and irreversible loss of Antarctic ice sheets causing sea level rise, retreat of the glaciers in the Hindu Kush, and other events which could have a compound effect on global warming.

We just don't know yet when these inflection points will be reached. We would literally be playing with fire to ignore the signals in front of us and carry on as usual - where warming of 5-6 degrees by the century's end, is the estimate. If that happened the outcome would be truly apocalyptic.

But there is hope within all the doom & gloom, the public discourse on climate change has changed immeasurably, ten years' ago scientists were called out as crackpots when they sounded the warning bell, today, public discourse has switched in their favour. And we know that humanity can act quickly for the common good, as last year showed us: COVID-19 vaccines were developed for in record time.

1920s immunisation

The 1920s saw great advances in vaccine development too (tuberculosis, diphtheria, scarlet fever, tetanus, whooping cough, were all firsts of that decade). As the saying goes, necessity is the mother of invention. And with COVID-19 and the inventiveness of vaccine development, this rang true. The need was clear and present. The need to address human induced climate change is also clear and present.

We have no excuse now not to apply the same urgency to how we look after the climate and wellbeing of our planet and reimagine the future. Yet we remain surprisingly complacent.

To the economy - it is important that we frame the discussion in a NZ context rather than a US-centric narrative, we learnt. The "roaring" 1920s saw real GDP growth of 25% in the US whilst New Zealand "miaowed" with a 7% decline of in real GDP, on the back two recessions. Then, as now, NZ commentators lamented reliance on commodity export single trading partners - the UK, now China. Though there is a big difference - China is the engine of global growth, whilst the UK was not growing at the time.
