«One of the main outcomes of this study is that older faunas, linked to environments that were disappearing due to increased
aridity at the time, were displaced to the north surviving temporally in local refugia
with more humid conditions, particularly in the region of Catalonia and the South of France» adds Manuel Hernández Fernández, professor at Universidad Complutense de Madrid and senior author of the study.

with them from the humid Midwest and East proved more important than
aridity, environmental sustainability, and differences in ecological settings.
Oxygen isotope ratios in carbonate sediments are correlated
with the ratio of precipitation to evaporation and thus indicate
aridity.

aridity changes up to 2010 are consistent
with model predictions, which suggest severe and widespread droughts in the next 30 — 90 years over many land areas resulting from either decreased precipitation and / or increased evaporation.

aridity and CO2 concentrations now complete, the mirroring of the climate change in the horse size is quite exact.
While there is evidence of a persistent relationship between periods of
aridity during the mid-Holocene and the MCA, as both are associated
with increases in radiation and cooler SST in the eastern Pacific [64], climate simulations suggest that current forcing by increased GHG may produce an opposite oceanic response in the future [65].
Spatial patterns of loss and gain showed contrasting latitudinal patterns,
with a westward range shift of species around the species - rich equatorial transition zone in central Africa, and an eastward shift in southern Africa; shifts which appear to be related mainly to the latitudinal
aridity gradients across these ecological transition zones
It was in fact a LEAP that terminated the last interglacial, the cold Late Eemian
Aridity Pulse which lasted 468 years and ended
with a precipitous drop into the Wisconsin ice age.
Rainfall change and variability is very likely to affect vegetation in tropical grassland and savanna systems
with, for example, a reduction in cover and productivity simulated along an
aridity gradient in southern African savanna in response to the observed drying trend of about 8 mm / yr since 1970 (Woodward and Lomas, 2004a).
Increased dust flux may increase
aridity and suppress rainfall outside deserts,
with opposite effects under wetting scenarios (Bachelet et al., 2001; Hardy, 2003; Prospero and Lamb, 2003; Lioubimtseva and Adams, 2004), leading to indirect effects on the vulnerability of remote regions to climate change.
Taken together, the average of the warmest times during the middle Pliocene presents a view of the equilibrium state of a globally warmer world, in which atmospheric CO2 concentrations (estimated to be between 360 to 400 ppm) were likely higher than pre-industrial values (Raymo and Rau, 1992; Raymo et al., 1996), and in which geologic evidence and isotopes agree that sea level was at least 15 to 25 m above modern levels (Dowsett and Cronin, 1990; Shackleton et al., 1995),
with correspondingly reduced ice sheets and lower continental
aridity (Guo et al., 2004).
