Model Intercomparison Projects (MIPs) are fundamental to our understanding of how the land surface responds to changes in climate. However, MIPs are challenging to conduct, requiring the organization of multiple, decentralized modeling teams throughout the world running common protocols. We explored centralizing these models on a single supercomputing system.

- Forests can play a significant role in reducing climate change impacts and offering additional benefits to society, but they face increasing climate-related threats like fire and drought that may weaken their ability to absorb carbon.
- Recent scientific advancements in understanding forest physiology and ecology are enhancing our ability to evaluate these risks to forest stability.
- Improved risk assessment can guide policymakers in utilizing forests more effectively as natural solutions for climate change.
Article Synopsis
- Plants help reduce CO2 in the atmosphere, which is important for slowing down global warming.
- * Over the years, human activities have greatly increased their influence on how much CO2 plants take in, especially from 57% to 94% of vegetated areas between 1901 and 2010.
- * The main reasons for this increase in CO2 absorption are extra CO2 from human sources and nitrogen from fertilizers, especially in tropical and industrial regions since the 1970s.
Terrestrial ecosystems carbon and water cycles are tightly coupled through photosynthesis and evapotranspiration processes. The ratios of carbon stored to carbon uptake and water loss to carbon gain are key ecophysiological indicators essential to assess the magnitude and response of the terrestrial plant to the changing climate. Here, we use estimates from 10 terrestrial ecosystem models to quantify the impacts of climate, atmospheric CO concentration, and nitrogen (N) deposition on water use efficiency (WUE), and carbon use efficiency (CUE).
