Abstract

fetched live from OpenAlex

This study examines the statistical relationship between global economic development measured by global GDP per capita, and global temperature change. The main goal for this paper is to determine whether the increasing global economic development is associated to annually global temperature increase. Three regression models are employed in this study: linear regression, multiple linear regression, and polynomial regression. The linear regression model is considered as the base model for whole analysis. The numerical and figure outcomes provide the direct linear relationship between GDP and temperature change. The multiple regression model extends the analysis by using three control variables, which are urbanization rate, CO2emissions from land use, and CO2emissions from industry. The polynomial regression model is applied to test for potential nonlinear dynamic relationship. The results show that the linear models suggest a positive association between economic growth and global temperature rise. In contrast, the polynomial models reveal nonlinear patterns resembling the environmental Kuznets curve. Overall, the findings highlight the importance of including demographic and emissions-related variables in climate–economy research and provide new evidence for ongoing debates on the complex interaction between economic development and climate change.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
