<abstract>
<p>The climate of the early nineteenth century is likely to have been
significantly cooler than that of today, as it was a period of low solar
activity (the Dalton minimum) and followed a series of large volcanic
eruptions. Proxy reconstructions of the temperature of the period do not
agree well on the size of the temperature change, so other observational
records from the period are particularly valuable. Weather observations have
been extracted from the reports of the noted whaling captain William Scoresby
Jr., and from the records of a series of Royal Navy expeditions to the
Arctic, preserved in the UK National Archives. They demonstrate that marine
climate in 1810–1825 was marked by consistently cold summers, with abundant
sea-ice. But although the period was significantly colder than the modern
average, there was considerable variability: in the Greenland Sea the summers
following the Tambora eruption (1816 and 1817) were noticeably warmer, and
had less sea-ice coverage, than the years immediately preceding them; and the
sea-ice coverage in Lancaster Sound in 1819 and 1820 was low even by modern
standards.</p>
