Warming climate is putting more metals into Colorado's mountain streams
ScienceDaily - Geography News
by
2d ago
Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, presenting a concern for ecosystems, downstream water quality and mining remediation, according to a new study. Natural chemical weathering of bedrock is the source of the rising acidity and metals, but the ultimate driver of the trend is climate change, the report found, and the results point to lower stream volumes and exposure of rock once seale ..read more

World's oases threatened by desertification, even as humans expand them
ScienceDaily - Geography News
by
2d ago
Oases are important habitats and water sources for dryland regions, sustaining 10% of the world's population despite taking up about 1.5% of land area. But in many places, climate change and anthropogenic activities threaten oases' fragile existence. New research shows how the world's oases have grown and shrunk over the past 25 years as water availability patterns changed and desertification encroaches on these wet refuges ..read more

The Italian central Apennines as a source of CO2
ScienceDaily - Geography News
by
3d ago
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the type of rock. At depth, the heating and melting of carbonate rock leads to the outgassing of CO2 at the surface. In the central Italian Apennine Mountains, researchers have now investigated and balanced all of these processes in one region for the first time -- using, among others, analyses of the CO2 content in mountain rivers and springs ..read more

Marine microbial populations: Potential sensors of the global change in the ocean
ScienceDaily - Geography News
by
3d ago
Animal and plant populations have been extensively studied, which has helped to understand ecosystem processes and evolutionary adaptations. However, this has not been the case with microbial populations due to the impossibility of isolating, culturing and analyzing the genetic content of the different species and their individuals in the laboratory. Therefore, although it is known that populations of microorganisms include a great diversity, this remains largely uncharacterized ..read more

More sustainability in global agricultural trade
ScienceDaily - Geography News
by
3d ago
The EU wants to ensure greater sustainability in agricultural trade with the Global South -- with the aim of minimizing the environmental and climate-damaging effects of importing crops such as soya, palm oil, coffee, and cocoa. However, this aspiration is often not fulfilled in practice. Researchers have developed a new approach to identifying options for the sustainable trade of agricultural products. This approach requires a refined analysis that shows how relevant the individual products are for the EU and the country of origin and what leverage effect they have. The researchers found that ..read more
