The reduction in growth of plants restricted by limitations on nutrients, temperature and/or water stress, didn't just reduce photosynthesis but led to negative feedbacks in plant carbon balance processes.
When researchers compared the results derived from FLUXNET data with the results synthesised from the literature, they found substantial differences. As a result, they suggest a new benchmarking metric that could be used to test existing hypotheses embedded in climate models and have mapped a path forward involving using further detailed observations to improve the way coupling/decoupling processes currently represented in climate models.
This paper, A census of atmospheric variability from seconds to decades, synthesises and summarises atmospheric variability on time scales from seconds to decades through a phenomenological census. It focuses mainly on unforced variability in the troposphere, stratosphere, and mesosphere.
This study explored the key sources of uncertainty when scaling leaf-level understanding of water-use efficiency to ecosystem scales. The results provide key insights into interpreting (ecosystem-scale) eddy-covariance derived water-use efficiency in an ecophysiological context.
This paper combines existing global evapotranspiration estimates to create a new global product with an observationally constrained estimate of uncertainty. It utilises the latest release of ground-based estimates to show that even point-based evapotranspiration estimates have information about much larger spatial scales.
Summer in some regions of the world will become one long heatwave even if global average temperatures rise only 2°C above pre-industrial levels and certain regions may become close to unliveable if temperatures increase by 5°C. Even with just a 1.5°C increase in global temperatures there are significant changes to the length, intensity and frequency of heat waves in every part of the world.
