313: Climate Apocalypse

Episode Summary

Executive Summary: The episode uses the “Curse of Akkad” to explore whether ancient collapse stories reflect climate apocalypse or a more complex mix of environmental stress, politics, disease, and resilience. Historian Peter Frankopan argues climate has always shaped history, but rarely alone; volcanic eruptions, pathogens, institutions, and inequality often determine outcomes. The discussion then turns to modern climate change, biodiversity loss, and adaptation challenges.

Main Topics: The Curse of Akkad as climate evidence (Priority: 5/5): The hosts open with the Akkadian famine text and ask whether it records climate catastrophe or rhetorical exaggeration. Frankopan says it can be tested against scientific evidence like ice cores, pollen, and regional environmental records. Climate change as one factor among many (Priority: 5/5): Frankopan repeatedly stresses that climate shifts matter, but outcomes depend on politics, social structure, disease, and human adaptation rather than climate alone. Volcanoes, disease, and historical turning points (Priority: 5/5): The episode highlights how eruptions in the 6th century, Santorini, and Tambora altered disease environments and helped trigger major crises such as plague and cholera. Long-run climate stability and imperial success (Priority: 4/5): The Roman warm period is presented as a globally stable phase that helped empires like Rome, China, and parts of Mesoamerica, though political resilience still mattered more than climate alone. Modern fossil-fuel era and accelerating risk (Priority: 5/5): The Industrial Revolution and especially post-World War II fossil-fuel use are framed as the main drivers of today’s climate crisis, biodiversity loss, and supply-chain fragility. Resilience, inequality, and political legitimacy (Priority: 4/5): The conversation argues that climate stress amplifies inequality and can weaken trust in democracy, while resilient states and institutions can sometimes absorb shocks. Historical perspective and optimism (Priority: 4/5): Despite the bleak subject, Frankopan argues against doomism, emphasizing human ingenuity, adaptation, and the value of historical perspective for policy and public understanding.

Key Arguments: Ancient collapse texts like the Curse of Akkad are not straightforward evidence; they must be cross-checked with scientific proxies such as ice cores, pollen, and regional environmental records. Climate stress rarely causes collapse by itself; it interacts with leadership, institutions, inequality, disease, and logistics. Volcanic eruptions can matter more than temperature change alone because they alter atmospheric conditions and pathogen behavior, helping diseases like plague spread. The 6th-century crisis was driven not just by cooling but by volcanic eruptions that intensified the Justinianic plague. The Little Ice Age is a useful framework, but its chronology and causal weight are debated; political resilience explains why some places weathered it better than others. The Roman warm period shows that stable climate can support imperial expansion, but logistics and governance remain essential. Modern climate change is qualitatively different because fossil-fuel combustion has accelerated environmental change, especially since World War II. Biodiversity loss, not just human suffering, is central to the current crisis and may already amount to a sixth mass extinction. Adaptation is harder because climate risk is entangled with energy insecurity, inflation, political fragmentation, and declining trust in institutions. Historical responsibility matters: wealthy countries have benefited most from industrialization, while many environmental costs have been outsourced to Asia and the Global South.

Data Points: Date of the Curse of Akkad: around 2250 BC - Frankopan identifies the text as an early example used to test climate-history links. Age of the Akkad text: about 4,500 years ago - Used to frame the limits of written evidence and the value of scientific proxies. Volcanic crisis period: 530s and early 540s - Linked to climate shifts and the Justinianic plague. Santorini eruption: around 1600 BC - Cited as a volcanic event that affected Crete and disease environments. Tambora eruption: 1815 - Referenced as the trigger for the Year Without a Summer. Year Without a Summer: 1816 - Used to connect climate disruption to social unrest and cholera’s spread. Roman warm period: roughly Augustus era onward - Described as a globally stable climate phase aiding Roman expansion. Roman imperial instability: 25 emperors in 40 years; 65 would-be emperors - Used to show how small shocks can magnify into political collapse. Fossil fuel use since WWII: about 85% of all fossil fuel burned - Illustrates how recent emissions dominate the climate problem. Fossil fuel use since 1989: about 50% - Shows the speed of recent emissions growth. Polluted cities: 496 of the world’s 500 most polluted cities are in Asia - Used to discuss outsourced environmental costs. Fashion industry emissions: around 10% of global greenhouse gas emissions - Compared with aviation and shipping combined. Water for one pair of jeans: 7,500 litres - Example of hidden environmental cost in consumer goods. Climate-change TV/radio mentions: about 3,000 times - BAFTA-commissioned report cited to show public discourse levels. Dog mentions on TV/radio: 110,000 times - Used to contrast climate coverage with everyday topics. Cheese mentions on TV/radio: about 130,000 times - Another contrast showing climate under-discussed relative to other subjects. Under-45s skeptical of elections: 60% - Cited to show democratic fragility under stress. New York City energy use: more than all of sub-Saharan Africa combined - Used to illustrate global inequality in consumption. U.S. Department of Defense emissions: largest institutional producer of greenhouse gases - Example of major institutional climate impact. Cattle urine-latrine research: significant environmental and climatic benefits - Mentioned as an example of creative mitigation research.

Pivotal Quotes: "“never let the facts get in the way of a good story”" — Peter Frankopan: On why ancient collapse narratives should be treated cautiously and tested against science. "“the thing that’s by far the most important is they change pathogen behaviour”" — Peter Frankopan: Explaining why volcanic eruptions can be more consequential than temperature change alone. "“betting against human ingenuity is really bleak”" — Peter Frankopan: His core optimistic argument about adaptation and resilience despite climate risk.

Implications: Listeners are urged to see climate history as complex, not deterministic: environmental shocks matter, but institutions, inequality, and adaptation shape outcomes. The episode suggests modern policy must focus on resilience, emissions, biodiversity, and honest accounting of global responsibility.
