Climate Change in Queensland Map Application (Completed)
Climate Risk Matrix Workshops (6 delivered across Qld)
High-resolution projections until 2099 for Queensland (10 km)

(Completed)

Climate extremes from high-resolution projections (Almost

complete)

Enhanced Climate Change in Queensland Map Application with

high resolution projections (In progress)

The Climate Change Science work so far:

Providing climate change projections at regional scale

GCM = Global Climate Model CCAM = CSRIO’s Conformal Cubic Atmospheric Model SST/SIC = Sea Surface Temperature and Sea Ice Concentration

Why downscale?

The higher resolution 10km model more accurately represents localised high rainfall events.

Global model (210 x 130 km) Regional model (10 x 10 km)

downscaling

Key climate change related issues facing

Queensland more extreme El Niño and La Niña events, tropical cyclones, convective storms, severe wind, fire weather, heat stress and multi-year droughts.

Validating the future projections with the past

experience.

More work still needs to be done….

SLIDE 12

We can do this using the palaeoclimate record

But to enable practical and meaningful decisions to be made using the climate change projections, we need to actively engage with industry and businesses.
