Pre-event (13 Jun 2024) and post-event (7 Aug 2025) satellite images of Dharali, Uttarkashi, India reveal how a sudden cloudburst unleashed mudflows that blanketed the Bhagirathi and Kheer Gad channels in thick grey sediment, erasing roads, orchards and buildings. #Disaster #Flood #ISRO #Cloudburst

Concerning trend shown in the Earth Overshoot Day chart (1971-2025). The date moves earlier each year, with 2025 at 1.8 Earths indicating unsustainable resource use. Over-consumerism is a key driver. Super rich should reduce their carbon footprint.

I’m having trouble separating natural forests from plantations in my LULC maps using GEE—they often get merged into same class.I want to separate them using unsupervised classification only. What additional data, indices or processing steps would you recommend to distinguish them more reliably?

Just discovered the “Insect Hotel” – logs drilled with varied-diameter holes to create nesting sites for solitary bees, wasps, ladybugs & other beneficial insects. Boosts pollination, natural pest control & local biodiversity.

While analyzing FAO WaPOR Biomass data, I noticed a striking pattern along a river: one bank shows high vegetation growth, the other much lower. Remote sensing (RS) data reveals these stark differences in Total Biomass Productivity (TBP), possibly due to irrigation, soil type, or groundwater. #IWMI

Most rivers, especially in remote or rural areas, have no streamflow gauges. That makes it hard to predict floods, manage water or plan infrastructure. Researchers use LSTM to estimate upstream flow based on observed downstream flow. @ciroh.bsky.social

Our choices this decade will shape the world our children inherit. A child born in 2020 faces different futures by 2090. We’re at +1.1°C since pre-industrial times. Low emissions = temperature stability. High emissions =warming beyond 2100
