Will Perth be affected by climate change?

Perth could see the average annual number of days with maxima over 35°C increase from 28 in the recent past (1971–2000 average) to 36 in 2030, and to 40 and 63 in 2090 for intermediate- and high-emission scenarios, respectively.

How will global warming affect Perth?

Western Australia, particularly the south-west, is vulnerable to climate change. Changing rainfall patterns, rising sea levels and increasing intense weather events pose a threat to the states water supply, agriculture, coastal infrastructure and natural habitats.

Is Perth becoming more humid?

Key points: A trough down the west coast is worsening humidity in WA’s south. Conditions are expected to ease by the weekend. But there is no clear trend to suggest Perth’s summer humidity is increasing long-term.

What is the water problem in Perth?

Over the last 50 years, Perth has seen a 20% decline in annual rainfall; this reduction in surface water has greatly affected groundwater recharge, which in turn has led to long-term drying effects in some areas.

What is wa doing for climate change?

The Western Australian Climate Policy sets out the State Government’s plan for a climate-resilient community and a prosperous low-carbon future. The policy underscores our commitment to adapting to climate change and to working with all sectors of the economy to achieve net zero greenhouse gas emissions by 2050.

Where in Australia is safest from climate change?

The study, published in the journal Sustainability, found Tasmania could become recognised “as Australia’s ‘local refuge (lifeboat)’ as conditions on the continental mainland may become less amenable to supporting large human populations in the future”.

What climate is Western Australia?

Western Australia has many types of climate, in the south-west, the climate is temperate, with winter rainfall (June-August) and four distinct seasons, to the north the climate is tropical with a wet season and a dry season (April to November) while in the rest of the land is arid or semi-arid.

Why is Western Australia so hot?

Easterly winds travelling over the hot, dry desert bring very hot, dry weather conditions to Perth. These winds are brought about by “anti-cyclones” (or high pressure systems), which are a prominent feature of Perth weather, and we see these almost every day in our weather charts.

Is Perth really running out of water?

Perth, much like Cape Town, was once almost entirely reliant on its dams. But the city’s rainfall has declined almost 20 per cent since the 1970s, and the amount of water flowing into the city’s dams has fallen from an average of 300 billion litres a year to just 25 billion litres.

Why does Perth have water scarcity?

Rainfall has decreased and the dams that once met most of Perth’s water needs are no longer being replenished. Our groundwater resources, which now supply most of our urban water needs, are under pressure due to increasing demand for water and the drying climate in the south west of the State.

Why is rainfall decreasing in Western Australia?

The decline in rainfall over the south-west is consistent with increasing greenhouse gas concentrations and cannot be explained solely by natural climate variability or changed land use, such as land clearing. There have been dramatic movement of isohyets to the west after about 1990.
