For the past several weeks, I have delved deeply into the content produced by scientific climate change deniers. By "denier" I mean those who argue that global warming is below the range expected by mainstream studies and by "scientific" I mean that handful of actual active researchers in climatology, rather than unqualified opinions. Without exclusion, I've found that these scientific deniers engage in extraordinary selection biases, unfounded speculations, and flawed logic. But, to the untrained eye, I can certainly see how they could be convincing; they appeal to ideological confirmation biases and, of course, they appeal to certain vested interests. Their influence is profound; there are very few climatology journal articles that are in the denier category, but the content makes up the overwhelming majority of related advertorials. The result is a profound disparity between an misinformed public opinion compared to scientific research, which, in a capitalist democracy, is reflected in the politics of demagoguery.

Two days ago, the World Meteorological Organization reported the largest recorded level of atmospheric CO2 and the largest increase in a single year (a reminder that CO2 remains in the atmosphere for a very long time). It follows Trump's decision to withdraw from the 2016 Paris Agreement, which sought to preferably limit global warming this century to 1.5 degrees C above pre-industrial levels, with a long-term objective of below 2.0 degrees. As COP30 approaches it increasingly becomes clear that voluntary agreements to a global problem is biased toward unenforceable lobbying even when adaptive and mitigative technologies exist and even when our first major tipping point (coral reef losses) looms, a situation that has been warned about for years even as fossil fuel subsidies increase - your taxes at work.

I am now in my third year as a climatology postgraduate, after many years of debating the issue and engaging in autodidactic research. When I started formal studies, it quickly became apparent to me that, despite international agreements and technological change, the most accurate trajectory was the RCP8.5 scenario; high-emissions, high-growth, high-population, the highest plausible temperature increase, i.e., the worst case scenario. Maybe it's the risk engineer disposition in me, but I think we should prepare against worst-case scenarios, especially when the costs are high. The problem is that they are so incremental; people understand the accretion of warming as explained by the popular metaphor of the "boiling frog" story that describes how people do not effectively react to creeping changes. Whilst it is a strong and appropriate metaphor, it is also a myth. A frog will react when the water is too hot for comfort. But I wonder whether humans are as clever as a frog.
