This cycle continues as seafloor spreading pushes the seafloor under continental margins in the process of subduction. As seafloor carbon is pushed deeper into the Earth by tectonic forces, it heats up, eventually melts, and can rise back up to the surface, where it is released as CO2 and re...
Black carbon (BC) is produced by incomplete combustion of biomass by wildfires and burning of fossil fuels. BC is environmentally persistent over centuries to millennia, sequestering carbon in marine and terrestrial environments. However, its production,
At the present time data on the coastal environment in relation to the global carbon cycle are very scarce and warrants more research in this area.doi:10.1016/0169-8095(93)90025-JJ. ServantAtmospheric ResearchCarbon cycle variations on the Earth’s surface during the last two glacial cycles. ...
Assessing global mean temperature rise using the average warming over the previous one or two decades will delay formal recognition of when Earth breaches the Paris agreement’s 1.5 °C guard rail. Here is what’s needed to avoid the wait. Richard A. Betts Stephen E. Belcher Peter A. Stott...

Planet Earth is made up of four overlapping subsystems that contain all of world’s land masses, water sources, living organisms, and gases. These four subsystems are known as spheres. Geographers break down the Earth’s systems into four spheres that make up the world’s air (atmosphere),...
