Wildfire observations reveal that 21% of black carbon aerosols contain multiple cores, and accounting for this morphology increases global absorption by 19%, highlighting a missing source of radiative...

Using globally consistent measurements and high-resolution modelling, this study finds that black carbon emissions are generally underestimated in the Global South.

There has been a lot of talk lately about whether commercial Earth observation (EO) companies could replace parts of NASA’s Earth science mission portfolio. With a new Administrator coming in, that de...

Ground-based radar is the primary means by which severe storms are monitored and tracked; however, due to limited coverage, important data is often missed over ocean and mountainous areas. On the othe...

Trends in precipitation volume, number of wet days, mean wet-day intensity in CONUS-404 are mostly statistically non-significant At the hourly resolution, significant increasing trends are found ...

While food systems drive ∼30% of global annual total greenhouse gas (GHG) emissions, the quantitative relationship between income inequality and food system emissions remains poorly characterized. Our research addresses this gap by quantifying disparities in per-capita food GHG emissions by income tier over three decades (1990–2020). Combining multiregional input–output modeling with life-cycle assessments, we reveal an unprecedented disparity: the top 10% of earners emit 21 times more (10.49 tCO2e yr–1) and the top 1% a staggering 73 times more (36.85 tCO2e yr–1) than the bottom 50% (0.50 tCO2e yr–1). Crucially, we demonstrate that current emission trajectories are incompatible with the 1.5 °C climate target (0.81 tCO2e capita–1 for food systems), necessitating reductions of 86–95% for the top 10% and 38–83% for the middle 40%, while the poorest half already align with this target in many regions. Our novel quantification of this “emissions divide” challenges conventional climate policies focused solely on production-side reforms, instead of spotlighting overconsumption by wealthy individuals as a critical yet overlooked leverage point. This work redefines equitable climate action by establishing that fairness in food-system decarbonization requires targeting high emitters─a transformative insight highlighting the need for differentiated mitigation strategies to simultaneously reduce emissions and ensure global nutrition security within planetary boundaries.
