The Year 2109 - Temperatures had been rising continuously while precipitation was accumulated in short but intense timeframes. The quantities of water were dramatically too high to absorb for the small areas of natural soil that had been left unsealed.
Median wind-speeds were increasing equally due to higher pressure gradient differences.
These two factors primarily contributed to the erosion and subsequent desertification of vast areas in Northern Europe. Attempts were made to stabilize the soil with flora more fit to sustain long periods of drought and hotter climates, but few of these succeeded in the long term. As a natural consequence a new fauna entered areas that had previously been domains for boreal and subtropical animals.
