"Projections indicate there may be an increase in the proportion of tropical cyclones in
the more intense categories (3-5), however a decrease in the total number of cyclones. By 2030, projections show that there may be a 60 per cent increase in severe storm intensity and a 140 per cent increase by 2070. Projections also indicate that tropical cyclones are moving southward as sea surface temperatures increase"

Sea Level Rise
"The global average sea level rose by close to 20 centimetres between 1870 and 2007."
"Sea levels rose at an average of 1.7 millimetres per year during the 20th century, and 3.4 millimetres per year from 1993 to 2007"

Climate change quote:
Generally for Queensland
"Rising sea-level, stronger tropical cyclones and increased intensity of oceanic storm surges are likely with climate change. A study has shown that tropical cyclone intensity around Cairns in northern Queensland could increase by up to 20% by about
2050. Stronger cyclones would increase the flood level associated with a 1-in-100 year flood in Cairns from the present height of 2.3 metres to 2.6 metres; a rise in sea-level of 0.1 to 0.4 metres would result in the flood level increasing further to 2.7 to 3.0 metres. This would result in flooding occurring over an area about twice that historically affected"
