The silicate carbon weathering sink (SCS) is the net carbon sink that affects the global carbon cycle over a period of millions of years or more. However, the magnitude, spatial pattern and evolution characteristics of global ...

The Arctic's greening, but it won't save us

There was a hope that as more plants start to grow in Arctic and boreal latitudes as our warming climate makes those regions more hospitable for plants, those photosynthesizing plants would work to help sequester the atmospheric ...
