A key statistic describing climate change impacts is the ‘social cost of carbon dioxide’ (SCCO2), the projected cost to society of releasing an additional tonne of CO2. Cost-benefit integrated assessment models that estimate the SCCO2 lack robust representations of climate feedbacks, economy feedbacks, and climate extremes. We compare the PAGE-ICE model with the decade older PAGE09 and find that PAGE-ICE yields SCCO2 values about two times higher, because of its climate and economic updates… 
Climate Impacts on Natural Capital: Consequences for the Social Cost of Carbon
The effects of climate change on natural systems will be substantial, widespread, and likely irreversible. Warmer temperatures and changing precipitation patterns have already contributed to forest
Social cost of carbon under a carbon-neutral pathway
Climate change is the challenge of the century, and achieving the goals of the Paris Agreement will require worldwide cooperation and mutual effort. Over 120 countries have made their net-zero
A meta-analysis of the total economic impact of climate change
Earlier meta-analyses of the economic impact of climate change are updated with more data, with three new results: (1) The central estimate of the economic impact of global warming is always
The effect of rainfall changes on economic production
A global assessment of subnational economic output for 1,554 regions worldwide over the past 40 years shows that increases in the number of wet days and extreme daily rainfall adversely affect economic growth, particularly in high-income nations and via the services and manufacturing sectors.
Climate-Society Feedback Effects: Be Wary of Unidentified Connections
Feedbacks within the climate-economy system are complex. The research analyzing the relationship between human activities and the climate is considerable, with particular focus on intra-system
Integrated perspective on translating biophysical to economic impacts of climate change
Estimates of climate change’s economic impacts vary widely, depending on the applied methodology. This uncertainty is a barrier for policymakers seeking to quantify the benefits of mitigation. In
Sustainability after COVID-19: pillars for a just transition
The vulnerability of the global economy has been starkly exposed by the COVID-19 pandemic. Longer term thinking and new approaches to development and prosperity are urgently required. In this paper,
Impact of Tokenization on Language Models: An Analysis for Turkish
It is found that increasing the vocabulary size improves the performance of Morphological and Word-level tokenizers more than that of de facto tokenizers and the ratio of the number of vocabulary parameters to the total number of model parameters can be empirically chosen as 20% for de factotokenizers and 40% for other tokenizers to obtain a reasonable trade-off between model size and performance.
