The Carbon Cycle:Like other minerals and gases, carbon is cycled through various organic and inorganic forms starting from the atmosphere, into living organisms, and back into the atmosphere. Some of this carbon, however, enters long-term storage in soils and sediments....
Animating the Carbon Cycle: How Wildlife Conservation Can Be a Key to Mitigate Climate ChangeStemming the loss of global biodiversity (especially diversity of wildlife species) and global temperature rise requires rapid actions enacted on a scope and spatial scale that have not yet been attempted. ...
” says Rawlins. This vertical flow includes things like burning fossil fuels, forest fires, leaking methane gas, and emissions from thawing permafrost. But there’s another part of the cycle—the horizontal. “Far less attention has been paid to how carbon is transfer...
