Climate Data Historical

Historical climate information provides significant context to understand future climate projections. Climate information can be analyzed though various levels, from temporal to spatial. In fact, temperature and precipitation both exhibit  substantial spatial and interannual variability. Therefore, the Climate Change Knowledge Portal (CCKP) provides users the options to visualize climate data via a map and/or as an annual cycle chart. The annual/monthly temperature and precipitation data is provided by the Climatic Research Unit (CRU) of the University of East Anglia (UEA), and reprocessed by National Center for Atmospheric Research (NCAR) of the University Corporation for Atmospheric Research (UCAR). A detailed metadata can be found here.

According to the IPCC Fifth Assessment Report (AR5) and Turn Down the Heat report:

  • Australia saw a severe heat wave during the Australian summer, with record temperatures and associated severe bush fires followed by extreme rainfall and flooding. Records were continuously broken, with the hottest summer on record and the hottest seven consecutive days ever recorded in Australia.
  • It is very likely that the numbers of cold days and nights have decreased and the numbers of warm days and nights have increased globally since about 1950.
  • There is also high confidence of decreases in dryness or drought in central north-west Australia.
  • However, it is likely that the frequency and intensity of drought decreased in central North America and north-west Australia since 1950.
  • There is a statistically significant decrease in Eastern Australia land-falling tropical cyclones since the late 19th century.
