South-East Queensland, of which Noosa Shire is a part, has been identified as a particular hotspot
for climate change impacts. Under the current projections, if global greenhouse gas emissions
continue on their current trajectory, Noosa can expect to experience the following climate change
impacts (refer Attachment 1):
    An increase of 1.62oC in the mean annual temperature by 2050 and an increase of 3.6oC by
     2090.
    An increase in the number of days above 35oC per year, from an average of 2.5 days
     currently to 7.4 days by 2050 and 35.4 days by 2090.
    The average duration of the longest heatwave in a year is expected to increase from
     approximately four days currently to twelve days by 2050 and fifty-six days by 2090.
    The number of hot nights where the temperature does not go below 20oC is likely to increase
     from the current twelve nights per year to around fifty-two by 2050 and up to one hundred
     and twelve nights by 2090.
    Whilst there is little expected change in total annual rainfall, the wet season is expected to
     get much wetter, increasing by 1.43% and 6.21% by 2050 and 2090 respectively. However
     the drier seasons are expected to see reduced rainfall by up to 6.15% by 2050 and up to
     13.38% by 2090.
    Projections indicate that by 2100, up to 2000 residential and tourist accommodation lots and
     29 commercial/retail properties could be within the projected storm tide inundation zone in a
     “1-in-100 year” scale storm. Up to 200 private residential lots, and 3 commercial/retail lots
     could be within the projected “1-in-100 year” coastal erosion prone area.
    It is expected that the number of tropical cyclones reaching the current Queensland tropical
     cyclone southerly extent (i.e. the Wide Bay region) will increase over time. In addition, a
     higher proportion of the tropical cyclones formed each year are expected to achieve Category
     4 and 5 intensity.
