DOI: 10.1016/j.epsl.2019.05.025
Abstract: Abstract Specific challenges still exist in our understanding of past greenhouse climate states. Whilst climate model simulations using atmospheric CO2 concentrations consistent with proxy estimates broadly align with lower latitude proxy temperature estimates, they struggle… read more here.

DOI: 10.1016/j.icarus.2016.10.006
Abstract: Abstract Shallow water simulations are used to present a unified study of three major storms on Saturn (nicknamed as Great White Spots, GWS) at different latitudes, polar (1960), equatorial (1990), and mid-latitude (2010) (Sanchez-Lavega, 2004;… read more here.

DOI: 10.1016/j.jaridenv.2017.07.004
Abstract: Abstract Because of the lack of leaves, the distributions of columnar cacti are limited by their capacity to trade off their photosynthetic chlorenchyma and their non-photosynthetic storage parenchyma. For species with wide latitudinal ranges, variations… read more here.

DOI: 10.1016/j.jastp.2018.02.003
Abstract: Abstract The equatorial- and low-latitude thermospheric dynamics is affected by both equatorial electrodynamics and neutral wave dynamics, the relative variation of which is dependent on the prevalent background conditions, which in turn has a seasonal… read more here.
