“LSM-TS provides annual global estimates of ambient population from 1975–2024 at ~90 m resolution, creating a spatially and temporally consistent reconstruction of population change designed for longitudinal analysis. Reconstruction of historical populations are driven by current LandScan Mosaic building-level population distributions, scaled by built-surface change from #GHSL … and calibrated to annual national-level estimates from U.S. Census Bureau…”

“LandScan is a globally recognized, R&D100-winning population data platform developed at Oak Ridge National Laboratory (ORNL). Its datasets provide human population distribution estimates down to 100 meter grid resolution. LandScan supports disaster response, humanitarian aid, environmental analysis, and urban planning by providing insights into where people live and how they move…”

“Gridded population data support assessments of human exposure, settlement change, infrastructure demand, and access to services, yet global datasets combining annual coverage over multiple decades with fine spatial resolution remain limited. LandScan Mosaic Time Series provides 50 annual estimates of global ambient population distribution at 3 arc-second resolution from 1975 through 2024. The series is anchored to the 2024 LandScan Mosaic surface, produced through a building-level population modeling workflow. Historical surfaces are reconstructed using annualized changes in built surface and derived first-level administrative population trajectories. Every layer, including 2024, is normalized to administrative targets scaled to annual country totals from the U.S. Census Bureau International Database. The dataset is distributed as 50 single-band Cloud Optimized GeoTIFFs on an identical WGS84 grid, with values representing estimated persons per cell. Its common grid and methodology support fine-scale longitudinal analysis of ambient population distribution while documented validation and limitations guide appropriate reuse…”

#Trump's rush to build #nuclear reactors across the U.S. raises safety worries
December 17, 2025
"Critics, however, worry that the tight July 4 deadline, political pressure and a lack of transparency are all compromising safety. Even a 'small' release of #radioactive material could cause damage to #people and the #environment around the test sites.
"This is not normal, and this is not OK, and this is not going to lead to success," warned #AllisonMacfarlane, a professor at the University of British Columbia who served as chairman of the #NRC under President Barack Obama. 'This is how to have an accident.' "

Google stellt ersten Atomreaktor-Standort für KI-Betrieb vor
"
"Künstliche Intelligenz gilt als Energiefresser. Zusammen mit Kairos Power will Google die eigenen KI-Server auch künftig mit ausreichend Strom versorgen – aus Kernenergie. Das Start-up baut nun ein erstes Atomkraftwerk im Rahmen der Kooperation."20.8.2025

#StrategicVoting by the #PrimaryFromTheCenter method survived a challenge by a #SobbingMAGA 💦 from #OakRidge. #JohnRagan lost his seat in the #TNleg state House of Representatives due to what he called “poison” votes - those cast by primary voters who are not in his opinion “bona fide #Republicans.” https://tennesseelookout.com/2024/09/09/tennessee-republicans-deny-oak-ridge-rep-john-ragans-challenge-of-august-primary-loss/
