Tree ring isotopes reveal an intensification of the hydrological cycle in the Amazon
Over recent decades the Amazon region has been exposed to large-scale land-use changes and global warming. How these changes affect Amazonia’s hydrological cycle remains unclear as meteorological data are scarce. We use tree ring oxygen isotope records to confirm that the Amazon hydrological cycle has intensified since 1980. Diverging isotopic trends from terra firme and floodplain trees from distinct sites (approximately 1000 km apart) in Weste…
The Amazon rain forest in South America is considered the green lung of the earth. Tree rings have now revealed a marked change in rain in the world's important region.
The Amazon Network of Socio-Environmental Information Raisg will present version 2.0 of the AMA platform, an advanced monitoring tool for the Amazon that strengthens regional capacity in the face of critical threats such as deforestation, forest fires and changes in land use. This version presents modules focused on highlighting pressures, symptoms and consequences on Amazonian ecosystems, underlining the strategic role of protected areas, indig…
Wet stations in the Amazon are increasingly wet, and dry, drier – The Observatorial
The study of trees rings in the Amazon He has revealed a worrying change in the rainy cycle of the last forty years: wet stations are increasingly wet and dry, drier stations. The study, published on Tuesday in the journal Communications Earth and Environment, explains that the signs of oxygen isotopes in the rings of […]
