Globally, thermodynamics explains an increase in atmospheric water vapor with warming of
around 7%/° C near to the surface. In contrast, global precipitation and evaporation are …

This review examines the role of the atmospheric evaporative demand (AED) in drought.
AED is a complex concept and here we discuss possible AED definitions, the subsequent …

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

The AR5 concluded that human influence on the climate system is clear, evident from
increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing …

Humans' ability to efficiently shed heat has enabled us to range over every continent, but a
wet-bulb temperature (TW) of 35° C marks our upper physiological limit, and much lower …

Atmospheric vapor pressure deficit (VPD) is a critical variable in determining plant
photosynthesis. Synthesis of four global climate datasets reveals a sharp increase of VPD …

Trends in surface air temperature (SAT) are a common metric for global warming. Using
observations and observationally driven models, we show that a more comprehensive …

Arid and semi-arid regions of the world are particularly vulnerable to greenhouse gas–
driven hydroclimate change. Climate models are our primary tool for projecting the future …

Background Influenza virus, respiratory syncytial virus, parainfluenza virus, and
metapneumovirus are the most common viruses associated with acute lower respiratory …

The increasing need to cool the air in our built environment is both a cause and an effect of
climate change. Air conditioning accounts for a large portion of global greenhouse gas …
