The 40Ar/39Ar dating results are discussed in terms of climatic condition changes during the Palaeogene that were favourable to the genesis of either Al- and Fe- or Mn-oxy-hydroxides in the course of development and evolution of the pisolitic formation.
Nowadays, the absence of suitable data that describes the urban landscape in climate relevant terms for climatic models is a significant impediment to progress, even if the physics that underpins these models is universal.
Fire activity is determined by a wide range of factors, including long and short term climatic conditions, climate seasonality, wind speed and direction, topography, and fuel biomass.
It could even be possible that short-term climatic fluctuations superimpose a long-term trend of aridification and contribute to ongoing change of environmental selective pressures.
Bangladesh is recognized to be one of the most highly vulnerable to climatic manifestations (short-term and long-term impacts of climate change) due to its unique geographic location, like dominance of floodplains, low elevation from the sea and lastly the socio-economical characters like high population density, high levels of poverty, and overwhelming dependence on nature.
Previous work on mosquito populations, for example, which have been linked to BU, shows that they are at their highest during periods of high short-term climatic variability, cited as the amount of short-term fluctuations around a mean climate state on a fine time scale.
These parental types respond differently to environmental conditions (e.g., predation, disease, and long-term climatic factors) by altering the condition, sex, and morph of their own offspring through mechanisms that persist across generations.
According to the palynological results, since 8200 cal BP highly variable climatic conditions in terms of moisture availability have occurred during the entire Holocene.
Dewar (2003) has since developed the climatic argument in terms of an increasing unreliability of rainfall, inhibiting rice cultivation as one moves east through Island Southeast Asia towards eastern Melanesia.
