Global Warming & Climate Change Impacts

We are motivated to help communicate this important information to the general public. How will the current anthropogenic global warming observed at an unprecedented rate impact your location, your assets and your plans in the future?

Integrated climate-warming trend reports (in PDF) are prepared for various locations in Australia and in the world using the new NASA Earth Exchange Global Daily Downscaled Projections dataset (NEX-GDDP, 2015; ~12 terabytes in file size), which was derived from the runs of 21 advanced Global Climate Models under two greenhouse gas emissions scenarios.

The NEX-GDDP dataset has been widely used for studies of climate change impacts and increasing public understanding of a rapidly warming climate. We analyse and compare average daily max and min temperature projections (by year or by month) from eight independently-developed global climate models:

• Australia: CSIRO-MK3.6.0 and ACCESS1.0 climate models

• North America: GFDL-CM3 and CCSM4 climate models

• Europe: CNRM-CM5 and MPI-ESM-MR climate models

• Asia: BNU-ESM and MIROC5 climate models

For Australia, we choose 559 Local Government Areas and the December (the first month of summer in Australia in the Southern Hemisphere) temperatures for making location profile reports (downloadable below) on climate-warming trends. For each location, consistent warming TRENDS across all eight global models have been observed. It is reasonable to project that the harsh warming climate in the future will make those natural hazards (e.g. heatwaves, bushfires and drought) directly driven by higher temperatures even worse, on this driest inhabited continent!

We also develop and distribute two types of accessible information products on this:

•  Tiled Web Maps on climate change projections & climate-warming trends (Demo 1 | Demo 2 | Demo 3). Users can choose projections by RCP 8.5 / RCP 4.5, climate models, max / min temperatures and projection periods (e.g. 2000-2050 or 2000-2100).

• Customised, white-label reports (similar to the location profile reports downloadable below) for clients who have unique exposure locations. This can be  delivered via Web APIs within seconds.
