Twelve glaciers, representing various types, were investigated between 2000 and 2005, in a region adjacent to the northern reaches of Billefjorden, central Spitsbergen ( Svalbard ). On the basis of measurements taken using reference points, DGPS and GPS systems, analyses of aerial photographs and satellite images, geomorphological indicators and archival data their rates of deglaciation following the “Little Ice Age” (LIA) maximum were calculated variously on centennial, decadal and annual time scales. As most Svalbard glaciers have debris-covered snouts, a clean ice margin was measured in the absence of debris-free ice front. The retreat rates for both types of ice fronts were very similar. All studied glaciers have been retreating since the termination of the Little Ice Age at the end of 19th century. The fastest retreat rate was observed in the case of the Nordenskiöldbreen tidewater glacier (mean average linear retreat rate 35 m a-1). For land-terminating glaciers the rates were in range of 5 to 15 m a-1. Presumably owing to climate warming, most of the glacier retreat rates have increased several fold in recent decades. The secondary factors influencing the retreat rates have been identified as: water depth at the grounding line in the case of tidewater glaciers, surging history, altitude, shape and aspect of glacier margin, and bedrock relief. The retreat rates are similar to glaciers from other parts of Spitsbergen . Analyses of available data on glacier retreat rates in Svalbard have allowed us to distinguish four major types: very dynamic, surging tidewater glaciers with post-LIA retreat rates of between 100 and 220 m a-1, other tidewater glaciers receding of a rate of 15 to 70 m a-1, land terminating valley polythermal glaciers with an average retreat of 10 to 20 m a-1 and small, usually cold, glaciers with the retreat rates below 10 m a-1.

Among the several crises that occurred in the 16th century, the famine crisis and high prices in the years 1569–1574 had exceptional significance, as its intensity, scope and duration far out-weighed other economic collapses of the century. Despite this, the course of events and the consequences have been of virtually no interest to historians over the years, which begs the question: why? As it seems, the events connected with the crises in question were overshadowed in Western historiography by other numerous and significant political events at the time, such as the Battle of Lepanto (1571) and the Night of St. Bartholomew in France (1572). In the Polish-‑Lithuanian state, in contrast, between 1569 and 1574, the famine and high prices coincided with a crisis of royal power and the state. This, indeed, drew the attention of historians, but only to political issues, among them the Polish‑Lithuanian union of 1569, the succession to the throne after the heirless Sigismund Augustus died, the first free election, religious disputes, the flight of King Henryk Walezy (Henry III), and the neighbouring wars, rather than to the social problems connected with the mass death of the poorest in the state, and the resulting economic problems. Therefore, in this article, the author synthesises the course of the famine crisis of 1569–1574 in the Polish‑Lithuanian state and hypothesises that the events and implications of this crisis largely preserved the mentality of the nobility in the following centuries and their dominance in the economic and political life of the Commonwealth. This crisis also influenced a choice of different path for development of the Commonwealth compared to other European countries. To clarify, the author does not claim to have exhausted the subject, and the article is intended to spur a discussion and further detailed research.
