Australia\u2019s national climate risk assessment report, released last week<\/a>, revealed a horrifying future if urgent action to address global heating was not taken.<\/p>\n

The report looked at 10 \u201cpriority hazards\u201d \u2013 such as bushfires, flooding and extreme heat \u2013 and the risks they presented across Australia\u2019s way of life (you can read about the key takeaways from the report here<\/a>).<\/p>\n

Accompanying the report was a new tool from the Australian Climate Service which provides access to data about climate hazards and risks<\/a>.<\/p>\n

Here, I\u2019ve brought together some of the maps released by the ACS which show just how bad things will get for heatwaves, drought and coastal flooding.<\/p>\n

It is important to note that the worst outcomes shown on these graphics can still be avoided if urgent action is taken to reduce greenhouse gas emissions<\/a>. The highest levels shown are based on a 3C increase in global temperatures which could happen as early as 2050 if emissions are not curbed.<\/p>\n

According to the ACS the number of severe and extreme heatwave days is projected to increase, with the greatest increase in the northern parts of Australia.<\/p>\n

As a consequence of the increase in temperatures and heatwaves, heat-related mortality is projected to increase dramatically under the worst global heating scenarios:<\/p>\n

Showing the modelled increase in heat-related mortality* for selected Australian cities under different global warming levels: 1.5, 2 and 3 degree increases<\/a><\/p>\n

Heatwaves are Australia\u2019s deadliest natural hazard, with one recent study estimating they caused as many as 1,009 deaths in Australia from 2016 to 2019<\/a>. The deaths attributed to heatwaves vary greatly depending on the methods used \u2013 the numbers are lower when only considering deaths that list heat as a contributing factor on official documents such as coroner records and death certificates, but far higher when statistical methods are used to estimate excess mortality associated with heatwave events<\/a>.<\/p>\n

Time spent in drought is projected to increase, especially for areas in southern Victoria, South Australia and Western Australia:<\/p>\n

This will have obvious consequences for the agricultural industry, with reduced rainfall in growing seasons, in addition to crops facing higher heat stress from increased temperatures.<\/p>\n

In coastal areas, the ACS projects a significant increase in coastal flooding as sea levels rise<\/a>. The following map shows the average number of days each year exceeding the record flood level, which is the highest water level recorded over the baseline period (1995\u20132014) at each location:<\/p>\n

Minor flooding is also projected to increase significantly. For example, Sydney currently experiences minor flooding 31 days per year on average, but this could increase to 344 days a year with 3C of warming.<\/p>\n

One headline figure from the climate risk report is that by 2050, more than 1.5 million people would be living in areas around the country that would be hit by rising sea levels and coastal flooding.<\/p>\n

All of which underscores the importance of setting meaningful and ambitious targets for reducing emissions<\/a>.<\/p>\n
