Rusting Fool’s Gold in Glaciers a Sign of Increased Carbon

According to a new study published by USC scientists in the Proceedings of the National Academy of Science, rock and soil breakdown in glaciers generates more acidity and releases more carbon than other forms of natural weathering. Perhaps most interestingly, it is the elevated oxidation of pyrite, popularly known as “fool’s gold,” in the glacial

The Remote Paradise with a Plastic Problem

In the middle of the South Pacific Ocean, far from the urban, developed world, there’s a small, lush, green island with white sand beaches. However, this uninhabited, remote corner of the tropics—Henderson Island—also has a trash problem. The beaches of Henderson Island have the highest density of plastic waste in the world, according to a

Esri and Microsoft Partner to Accelerate Conservation

Land-cover mapping is a critical part of conservation planning, but current methods for collecting detailed geographic data are highly labor-intensive. Advanced technologies such as artificial intelligence (AI) can help, but they’re not yet widely accessible to those on the front lines of conservation and mapping. To improve this situation, Esri is collaborating with Microsoft to

Satellites Predicting Locust Plagues

Satellites are helping to predict favorable conditions for desert locusts to swarm, which poses a threat to agricultural production and, subsequently, livelihoods and food security. Desert locusts are a type of grasshopper found primarily in the Sahara, across the Arabian Peninsula and into India. The insect is usually harmless, but when they swarm they can

High Temperatures Linked to Changes in Loggerhead Turtle Nesting

  Loggerhead turtles are particularly susceptible to climate change as the risk of nest flooding increases and the health of hatchlings declines. Florida holds the world’s largest nesting population of loggerheads, yet little is known about the species’ activity in nearby Cuba. A recent article published in Chelonian Conservation and Biology suggests changing climate may

AGS White Paper: There Is No Downside to Sustainability

The American Geographical Society (AGS) released a White Paper, “A Geographical Framework for Sustainable Development,” which offers leaders in the public sector and private enterprise a geographically inspired long-term plan for confronting sustainability challenges facing the planet. With critical ecosystems increasingly under threat, conserving and restoring these ecosystems is key to promoting a sustainable future

Satellites Observe More Bleaching of Great Barrier Reef

Studying European Space Agency (ESA) Sentinel-2 images captured over the reef between January and April 2017, scientists working under ESA’s Sen2Coral project noticed areas that were likely to be coral appearing to turn bright white, then darken as time went on. The event was confirmed by two successive images captured in February, indicating the approximate

Detecting Methane Before It Becomes a Disaster

Methane leaks and explosions are uncommon, but they can be fatal, as witnessed in the April 2017 Firestone, Colo., explosion that killed two men and seriously injured one woman. In May 2017, the Colorado Oil and Gas Conservation Commission issued a Notice to Operators that requires systematic inspection of their inventory of flowlines—active as well
