The temporal evolution of Southern Hemisphere hydroclimate through the Last Interglacial
The Last Interglacial (LIG), 130-116 ka, is an excellent analogue for understanding potential future directions of climate under ongoing warming, where precipitation patterns are particularly uncertain. The spatial and temporal patterns of hydroclimate in the Southern Hemisphere (SH) have received less attention than in the Northern Hemisphere. Therefore, this study provides a comprehensive, transparent, and expandable database of hydroclimate-in…
Best of times, worst of times
The 2022 oil and gas crisis resulted in record fossil-fuel profits globally that rehabilitated the oil and gas industry, obstructed the energy transition and contributed to inflation, but their magnitude and beneficiaries have been insufficiently understood. Here we show the size of profits across countries and their distribution across socio-economic groups within the United States, using company income statements, comprehensive ownership data a…
Stranded fossil-fuel assets translate to major losses for investors in advanced economies
The distribution of ownership of transition risk associated with stranded fossil-fuel assets remains poorly understood. We calculate that global stranded assets as present value of future lost profits in the upstream oil and gas sector exceed US$1 trillion under plausible changes in expectations about the effects of climate policy. We trace the equity risk ownership from 43,439 oil and gas production assets through a global equity network of 1.8 …
The role of enhanced rock weathering deployment with agriculture in limiting future warming and protecting coral reefs
Meeting the net-zero carbon emissions commitments of major economies by mid-century requires large-scale deployment of negative emission technologies (NETs). Terrestrial enhanced rock weathering on croplands (ERW) is a NET with co-benefits for agriculture, soils and ocean acidification that creates opportunities for generating income unaffected by diminishing carbon taxes as emissions approach net-zero. Here we show that ERW deployment with cropl…
An integrative approach to estimating productivity in past societies using Seshat
This article reports the results of a collaborative effort to estimate agricultural productivities in past societies using Seshat: Global History Databank. We focus on 30 Natural Geographic Areas (NGAs) distributed over 10 major world regions (Europe, Africa, Southwest Asia, South Asia, Southeast Asia, East Asia, Central Eurasia, North America, South America, and Oceania). The conceptual framework that we use to obtain these estimates combines th…
An Introduction to Seshat
This article introduces the Seshat: Global History Databank, its potential, and its methodology. Seshat is a databank containing vast amounts of quantitative data buttressed by qualitative nuance for a large sample of historical and archaeological polities. The sample is global in scope and covers the period from the Neolithic Revolution to the Industrial Revolution. Seshat allows scholars to capture dynamic processes and to test theories about t…
Past Extinctions of Homo Species Coincided with Increased Vulnerability to Climatic Change
Agricultural productivity in past societies
Agricultural productivity, and its variation in space and time, plays a fundamental role in many theories of human social evolution. However, we often lack systematic information about the productivity of past agricultural systems on a large enough scale in order to be able to test these theories properly. The effect of climate on crop yields has received a great deal of attention resulting in a range of empirical and process-based models, yet th…
Carbon dioxide and climate impulse response functions for the computation of greenhouse gas metrics
The responses of carbon dioxide (CO2) and other climate variables to an emission pulse of CO2 into the atmosphere are often used to compute the Global Warming Potential (GWP) and Global Temperature change Potential (GTP), to characterize the response timescales of Earth System models, and to build reduced-form models. In this carbon cycle-climate model intercomparison project, which spans the full model hierarchy, we quantify responses to emissio…
