Is the world getting wetter or drier? By Colin Prentice

Earlier this year Steven Sherwood (UNSW) and Qiang Fu published a short note in Science suggesting that the world is, in fact, getting drier, as a result of anthropogenic climate change. Now we know that global precipitation tends to increase with global mean temperature; this is shown not only by models (there is a very … Continue reading Is the world getting wetter or drier?

Interactions between the carbon and nitrogen cycles under rising atmospheric CO2. By Cesar Terrer Moreno

Elevated CO2 (eCO2) triggers a cascade of effects on plants from above to below-ground that may alter nitrogen (N) availability, with important consequences for plant growth and carbon (C) storage. From Free-Air CO2 Enrichment (FACE) experiments we know that eCO2 can potentially increase both photosynthesis and net primary production (NPP). However, in some experiments the … Continue reading Interactions between the carbon and nitrogen cycles under rising atmospheric CO2. By Cesar Terrer Moreno
