For all species, the relationship with temperature is an asymmetric bell-shaped curve. This means biological processes increase in line with temperature, reach a maximum, and then rapidly decline when it gets too hot.

We teamed up with colleagues from Canada, Scotland, Germany, Hong Kong and Taiwan to search for general patterns in how temperature affects life. To our surprise, everywhere we looked we kept finding that, indeed, 20°C is a pivotal temperature for many measures of biodiversity, and not only for marine species.

Follow-up studies showed this dip has been getting deeper since the last ice age about 20,000 years ago. And it has been deepening faster due to global ocean warming.

Exactly why 20°C is pivotal and energy-efficient for cellular processes may be due to the molecular properties of water associated with cells. These properties may also be why ~42°C seems an absolute limit for most species.

Research in Tasmania modelled the growth rates of microbes and multi-cellular organisms and found the most stable temperature for their biological processes was also 20°C.

This “Corkrey model” built on other studies showing 20°C was the most stable temperature for biological molecules. A third coincidence?

A greater awareness of this 20°C effect may lead to new insights into how temperature controls ecosystem processes, species abundance and distribution, and the evolution of life.

This means the many marine species that can adapt to global warming by shifting their geographic distribution are unlikely to go extinct due to climate change.

Recently, a New Zealand research group noticed the number of marine species did not peak at the equator, as has been commonly assumed. Rather, the number dipped, with peaks in the subtropics.

Despite the complexity of multi-cellular species, it is remarkable that the cellular-level temperature efficiencies are reflected in those other aspects of biodiversity.

While many species have evolved to live at warmer and colder temperatures, most species live at 20°C. Also, extinctions in the fossil record – including sponges, lamp shells, molluscs, sea mats (bryozoans), starfish and sea urchins, worms and crustaceans – were lower at 20°C.

As long as species can shift their ranges to adapt to global warming, the 20°C effect means there will be local increases in species richness up to an annual average of 20°C. Above that, richness will decline.

That life seems centred around 20°C implies fundamental constraints that compromise the ability of tropical species to adapt to higher temperatures.

The 20°C effect is the simplest explanation for the above phenomena, including: trends in species richness and genetic diversity with temperature; extinction rates in the fossil record; biological productivity; optimal growth rate; and marine predation rates.

Globally, the range of temperatures that reef fishes and invertebrates live at is narrowest among species whose geographic distributions centred on 20°C. The same effect is seen in microbes.

We know many species can live at much colder or warmer temperatures than humans. But our systematic review of published research found the thermal ranges of animals, plants and microbes living in air and water overlap at 20°C. Could this be a coincidence?

When the number of species was plotted against the average annual temperature, there was a decline above 20°C. A second coincidence?

Mark John Costello received funding from the Royal Society of New Zealand-Te Apārangi that contributed to this research..

The mathematical Corkrey model predicts that thermal breadth should be minimised, and biological processes most stable and efficient, at 20°C. In turn, this should maximise species richness across all domains of life, from bacteria to the multi-cellular plants and animals. The model therefore provides a theoretical explanation for this “20°C effect”.

As species evolve to live at temperatures above and below 20°C, their thermal niche gets wider. This means most can still live at 20°C even if they inhabit hotter or colder places.
