1. Models are not infallible.
When dealing with complex subject matter involving lots of uncertainties, unknowns and data gaps, modelling will almost certainly be wrong. That doesn’t make them worthless but nor does it mean they should be elevated to infallible status and acted upon as though they constitute proof of something.
If we can’t get epidemiological models right involving trajectories of months what is the chance of climate models being correct considering they involve substantially greater uncertainty, unknowns and data problems involving trajectories of decades to centuries?

2. Experts can get it wrong.
The pandemic has shown that epidemiologists and health experts the world over have got COVID-19 wrong at one stage or another.
The most famous example is the Imperial College model that forecast 2.2m deaths in the United States and over 500,000 deaths in the UK. Critics have argued this was never plausible but it was the catalyst for UK lockdown policy.

3. Experts can disagree
Experts can disagree and this is normal in science (and policy making).
During the pandemic, health experts across the world have disagreed over epidemiology models (e.g. R0) ranging from thousands of deaths to millions, over treatments (i.e. the efficacy of anti-virals and anti-malarials), over who and how to test (targeted (symptomatic) versus broad based (even antibody testing), how to record cases and fatalities (e.g. Italy counting deaths with COVID the same as due to COVID, Belgium recording deaths suspected to be COVID related but not verified), the origin and nature of the virus (laboratory/synthetic or wet market/natural), over what the public health response should be (full lockdowns, targeted lockdowns, Sweden (minimal) or something in-between), and the susceptibility of children to the virus, leading to divergence on school closures.

4. The Precautionary Principle β No such thing as a free lunch
The COVID-19 crisis is a classic case of the precautionary principle in action. The policy measures put in place have been justified by the worse case scenarios of epidemic models forecasting mass deaths and hospital systems in collapse. These scenarios have been hyped up by an alarmist media presenting such scenarios / predictions as established fact.
Part of the problem stems from politicians abdicating responsibility for decision-making and hiding behind health experts as human shields. These experts have nothing to gain and everything to lose from underestimating the epidemic. No-one wants to be blamed for hundreds of thousands of preventable deaths.

5. If you can’t trust the WHO in a pandemic why would you trust the IPCC on climate change?
The neo-liberal (in international relations terms) notion that the UN (and other international institutions) are independent actors working altruistically for the global good has been blown to bits during the COVID-19 pandemic.
The conduct of the WHO and its complicity with China throughout the pandemic has demonstrated what realists have always known, i.e. international institutions are not independent actors, but instead reflect the interests of great powers in the international system.

6. If you canβt trust the Chinese in a pandemic how can you trust them on climate?
The COVID crisis also demonstrates why should not trust a communist dictatorship to act truthfully, transparently or ethically, much less put global interests above national interests even in times of an international crisis.
If we can’t believe China about infection rates, how can we believe their carbon accounting? If we can’t trust China to reduce the spread of a virus, how can we trust China to reduce the growth in CO2 emissions? If we believe China has captured/corrupted the WHO how do we know it hasn’t captured/corrupted the IPCC? If China will prioritise national interest in a health crisis, why won’t China prioritise national interest in a climate crisis? If we don’t believe China action/excuses in a pandemic why would we believe China action/excuses on climate change? If we can acknowledge China is trying to exploit the health crisis geo-strategically (i.e. South China Sea military manoeuvres) and geo-economically (belt and road and coercive threats), why will it not exploit climate change in the exact same way?
