How vulnerable are Australia’s cities to extreme heat? Explore our maps | Extreme heat

As the Federal Government warns that the climate crisis will increase heat -related deaths, the data obtained by Guardian Australia shows the most vulnerable effect, which shows the most vulnerable parts of the major cities of Australia.

The new measure, called the researchers in RMIT, which is called the heat security vulnerability index, combines its temperature readings from satellites with socioeconomic factors such as structured environment and green space and education, especially heat -sensitive (such as old Australians and disabled).

The data show a high vulnerability in the external suburbs of West Sydney and Melbourne, Adelaide and other major Australian cities. However, it also shows high vulnerability in cold climates such as Hobart, Launceston and Albury.

You can explore thermal fragility in Australia on the map below:

“Usually when we think about climate change and think about heat, we think of the temperature of the land surface. [there are] Other factors that mean that you can be more or less heat sensitive. ”

Davn, factors such as access to real built environment and services, also recorded things such as age, pre -existing conditions and income. Some of them may be related and can unite each other-many elderly Australians have other conditions, for example, other conditions.

Uz We know that you sweat less as you get older, so we know it is harder to cool down. We know it until the age of 4, and you also find it hard to be thermoregule, ”he said.

“6 of 6 Australians It has cardiovascular disease. Cardiovascular disease, respiratory disease, diabetes, mental illness, neurological conditions, we know that these people will be more sensitive to heat. In other words, you have more than one layer of complexity that contribute to heat fragility. “

Recently, a separate study published by researchers at the University of Monash found that Heatwaves caused 1,009 deaths in Australia between 2016-2019. The study found that communities with a larger share of elderly residents, in need of help and lower income or education, experienced higher death.

By opening the heat index, we can see how common these security gaps are and cut in our cities. The next map is shown “heat sensitivity olarak containing data on the structure, the environment, vegetation, vulnerable groups (very young, elderly and needy) and data on population density.

It also shows “adaptable ability olan, which are socioeconomic factors such as income and education. The RMIT partner Prof Qian (Chayn) developed Sun indices and said that heat sensitivity is more of a measure of heat sensitivity of community, the adaptable ability and the group showed the ability of the individual to reduce heat, such as being able to run an air conditioner.

Although the vulnerability is associated with socioeconomic factors, maps show clear exceptions – 5/5 in the heat security vulnerability index of Carlton and Fitzroy and Fitzroy and Woolloomooo and Sydney. They all make weak on heat sensitivity.

“Not only the people living in disadvantaged areas, but the heat will be vulnerable, but also the factors, age, probably the current conditions-unity. This is not just a simple story that applies to a group. In fact, it is valid throughout the country.”

“When you look at the maps, you will see less heat fragility in certain areas of more socioeconomic advantage. However, they do not exclude them because there are areas where older people can have a very high rate and they can be rich, but they will still be vulnerable due to the environment and pre -existing conditions.”

The last map shows the heat data captured by the satellites in the same suburbs as the maps above. Here, most of the vulnerable places against heat came to the fore here – Sun, Melbourne is the most vulnerable area in the West in the West and said, “It is a very open urban heat island. [effect]”. However, you can see similar patterns in most cities in data.

Both Savern and Sun said that data shows the need to improve planning processes to take into account the interaction of all these factors.

“Planning is great difficulty. We do not think of the connection in different directions. Governments are divided into portfolios, but we [need] An integrated approach to think about planning a livable place. “
