In the Amazon rainforest, scientists are pumping carbon dioxide into the canopy to simulate atmospheric conditions that may arise due to climate change to study how the biome adapts to heightened levels of carbon dioxide. Predicting the future The project is called AmazonFACE, short for Free-Air CO2 Enrichment. It is located near Manaus, the largest…
Concrete as a potential carbon sink: Ambitious goals, significant hurdles
By replacing conventional concrete aggregates with carbon-based materials, scientists at Empa believe large amounts of CO₂ could be permanently stored in building products. Their concept, “Mining the Atmosphere,” aims to help reduce atmospheric CO₂ levels to 350 parts per million — roughly the 1988 benchmark. To remove CO₂ from the atmosphere is “a very energy-intensive…
