Banking on yesterday’s ‘normal’ is the worst form of denial
By David Salt
As 2020 draws to a close everyone is praying for a return to ‘normal’. We crave free social (mask-less) interaction and we all want to go to the beach for a swim without fear of catastrophic bush fires. And we want to jump on a plane and head to exotic locations and not worry about our health. And we also want the economy to be strong so we and our children are gainfully employed.
None of this was available to us in 2020 but hopes are high for decent rain this summer (in Australia, anyway), and effective CoVID vaccines are being deployed so there are growing expectations that we may now be able to control the CoVID pandemic.
But does that mean a return to ‘normal’ is coming our way? Our political leaders would like you to believe it; and all the rhetoric is about firing up the economy so the good times can flow.
Three new reports on what climate change is doing to our environment, society and economy paint a very different picture.
Bye bye world heritage
Last week the IUCN released a sobering Outlook report on the condition and trajectory of the planet’s 252 natural World Heritage sites. It found that a third of these sites are being threatened by climate change.
The outlook for five Australian World Heritage sites including the Great Barrier Reef, the Blue Mountains and the Gondwana rainforests, has deteriorated markedly in recent years. The conservation outlook for the Great Barrier Reef has worsened from “significant concern” to “critical” – the most urgent status under the IUCN system. Of course, the GBR is in serious trouble having suffered its third mass coral bleaching in five years during the 2019-20 (Black) summer.
Three years ago UNESCO’s World Heritage Centre predicted that under a business-as-usual emissions scenario all 29 coral-containing World Heritage sites would cease to exist as functioning coral reef ecosystems by the end of this century.
Keep in mind that World Heritage status is only awarded to places of outstanding universal value and where national governments make commitments to protect those values. Australia acknowledges the existential threat that climate change poses to the Great Barrier Reef but still refuses to taken any meaningful action on reducing our own emissions, let alone campaigning for better emission reductions around the world. That contradiction makes my country a major convention abuser.
Hello health blues
And if the loss of our world’s most precious natural ecosystems doesn’t sober you up, then maybe the annual report from The Lancet on Health and Climate Change will. Among other things it found:
-there were 296,000 heat-related premature deaths in people over 65 years in 2018 (a 54% increase in the last two decades),
-that global yield potential for major crops declined by 1.8–5.6% between 1981 and 2019
-145 million people face potential inundation with global mean sea-level rise of one metre. This jumps to 565 million people with a five metre sea-level rise.
These numbers put CoVID impacts into the shade but our political leaders feel free to ignore them because they range over temporal and spatial scales that lie beyond their electoral timeframes.
However, as the authors of The Lancet report note: “We cannot afford to focus attention on the COVID-19 pandemic at the expense of climate action.”
Adding up our sovereign climate risk
Mirroring The Lancet’s report but coming from the economic end of town, a new report from Four Twenty Seven (an affiliate of Moody’s) has assessed sovereign climate risk. Among other things it found:
-Heatwaves: Over 25% of the world’s population in 2040 could be in areas where the frequency and severity of hot days far exceeds local historical extremes, with negative implications for human health, labour productivity, and agriculture. In some areas of Latin America, climate change will expose 80-100% of agriculture to increased heat stress in 2040.
-Flooding: By 2040, the number of people exposed to damaging floods is predicted to rise from 2.2 billion to 3.6 billion people, or from 28% to 41% of the global population, with roughly $78 trillion, equivalent to about 57% of the world’s current GDP exposed to flooding.
-Tropical storms: Over half of the population in small island developing nations are exposed to either hurricanes and typhoons or coastal flooding amplified by sea level rise. In the United States and China alone, over $10 Trillion worth of GDP (PPP) is exposed to hurricanes and typhoons.
The new normal
These are just three reports in recent weeks. They are backed by hundreds of other reports, analyses and research programs from all sectors of society that have emerged throughout this year and over recent decades. And they all bear the same message – human induced climate change has disrupted the ‘normal’. The devastation of recent years is but a foretaste of what is to come.
Yes, we need action on carbon emissions today but we also need a real acknowledgement from our governments of what is happening around us.
In Australia we are led by a Conservative government that is in profound denial of what the ‘new normal’ means. They place their faith in technology to deliver an endlessly growing economy in which no-one needs to sacrifice a scintilla of their way of life – it’s win win all the way.
They believe the certainty of yesteryear will return with a few percentage points of extra productivity and maybe a slightly better resourced emergency services sector.
And this can be seen in their refusal to commit to zero net emissions by 2050. They claim they won’t make such a commitment till they fully understand its impact on economic growth, till they know its cost.
They believe their economic modelling of what lies over the event horizon is more robust and dependable than the hundreds and hundreds of evidence-based reports warning us of the impacts of the climate change today, tomorrow and in the coming decades.
The economy of 2050 will be so totally different, both in form and function, to the economy of 2020 that our Government’s position of using future economic cost to defend its lack of action on climate change today is fatuous, abhorrent and immoral. It is a fundamental denial of everything that’s happening around us today.
(This implicit denial also frequently spills over into explicit statements of denial. Consider yesterday’s outburst from Australia’s Resources Minister, Keith Pitt who castigated a climate change warning from the United Nations secretary-general as an inconsequential “grand statement”.)
A new niche for humanity
Our Government’s denial of what the new normal means for society leaves us vulnerable. They claim they are making Australia resilient, when in truth they are doing the opposite, leaving us exposed.
Earlier this year a group of eminent Earth systems scientists asked what this new normal meant for humanity. They found that temperature increases over the coming 50 years will see the migration of 1 to 3 billion people. One of the scientists, Marten Scheffer, explains the logic behind this analysis in a short engaging YouTube clip.
Hundreds of thousands of migrants fleeing Syria’s civil war destabilised much of Europe. We still don’t know what lasting scars this migration event will have. Multiply that by a hundred, by a thousand, and the world looks quite a different place.
We live in challenging times with an uncertain future. To be better prepared for that future we need real, widespread and effective efforts to eliminate carbon emissions. But we also need our leaders to acknowledge that this world is changing, and that they (with us) need to work with that change, not deny it.
