Climate catastrophes have been happening forever
Every particle of soil tells the story of climate change
It is appealing to imagine that humans can control the Earth’s climate and if we are careful, we can prevent catastrophes from happening.
However, historians, epidemiologists, ecologists, volcanologists, anthropologists, archeologists, geographers, cosmologists and geologists routinely document the effects of abrupt and cataclysmic climate events.
Indeed, the ground beneath our feet is there because of a stream of catastrophes from ice sheets several kilometers thick to volcanic events, floods, frosts, meteorites and microbial action. Every time you take a shovel full of soil, each particle tells the story of a series of climate events.
Ecologists have long observed that populations in ecosystems fluctuate apparently randomly without clear causes. At a casual glance populations of plants, animals and microorganisms appear to be stable. But when they are studied closely it can be seen that stability is a chimera.
Fear of natural disasters is justified
Black swans have devastated our planet
“Black swans” are a term used by economists to describe events that are completely unpredictable, and can set off a cascade of consequences. In the case of financial markets they can result in buying frenzies or market crashes. Small perturbations can escalate either way – it is impossible to predict how humans as a mass will react.
Black swans also happen with the Earth’s climate. One of the most notable happened 65 million years ago when the 135 million-year reign of the dinosaurs came to an abrupt end. There is a well-defined layer in rock strata, rich in otherwise rare minerals, called the K–Pg (previously K-T) boundary. It marks the point at which an asteroid struck the Yucatán Peninsula and within seconds triggered a die-off of 75% of the world’s animals and plants.
After the end of the last ice age the climate warmed up abruptly and Neolithic cultures thrived, building stone cities for the first time. In what is now Syria, the city of Abu Hureyra has been excavated. It was occupied between 13,000 and 9,000 years ago and then suddenly abandoned. Why? A paper in the journal Nature presents evidence that it was pulverized by “cosmic impacts.”
Climate is complex and it behaves unpredictably. The United Nations Intergovernmental Panel on Climate Change (IPCC) acknowledges it in the (Third Assessment Report, p. 771):
“The climate system is a coupled non-linear chaotic system, and therefore the long-term prediction of future climate states is not possible.”
Yet, alarmist scientists imply that, in the absence of humans, climate is fairly stable and its behaviour can be predicted. However, aside from intrinsic instability, the climate does not exist in isolation. Climate is interrelated with other systems including cosmic events (solar irradiation, magnetic fields and cosmic rays to name a few), tectonic events (including eruptions, earthquakes and tsunamis), ecological events (infestations, plagues, die-offs) and oceanographic changes (including changes in currents).
Climate Realists are "deniers" – really?
Climate catastrophes happen. Politicians should not pretend they are preventable.
We should use our resources to build resilience, protect our citizens and recover from adverse events of all sorts, rather than attempting to anticipate the unpredictable and prevent the unpreventable.
