The number and intensity of extreme weather events fueled by climate change that ravaged not just Australia, but many other regions of the world in the 2019-2020 era were unprecedented: massive fires, high heat, powerful cyclones, and devastating floods.
The effects of severe weather on our health and well-being are becoming more pronounced. Nearly 500 Australians were killed in recent bushfires. The flames killed 33 individuals immediately, while another 429 perished as a result of smoke inhalation. Heatwaves kill more Australians than all other severe occurrences put together.
Floods, droughts, and strong storms caused by climate change all have an impact on our personal and communal well-being.

TOPSHOT – State Emergency Service vehicles approach flooded residential areas in western Sydney on March 20, 2021, amid mass evacuations being ordered in low-lying areas along Australia’s east coast as torrential rains caused potentially “life-threatening” floods across a region already soaked by an unusually wet summer.
Extreme weather may be costly. The cost of extreme weather in Australia has more than quadrupled since the 1970s, reaching $35 billion in the last decade, according to new research from the Climate Council. Extreme weather events caused by climate change, as well as the effects of sea-level rise, might cost Australia $100 billion per year by 2038.
Climate change is limited to a 1.7°C increase over pre-industrial levels under “low emissions,” with emissions dropping to zero by 2100. In the “medium” scenario, emissions begin to fall by 2045, but in the “high emissions” scenario, no attempts are made to reduce emissions, leading temperatures to increase by more than 2 degrees Celsius by 2040 and 3 degrees Celsius by 2060.
According to the research, Queensland and New South Wales would bear two-thirds of the expense, with Melbourne particularly vulnerable to floods due to its closeness to key rivers.
Natural catastrophes, such as fires, floods, hailstorms, and hurricanes, already cost Australia $39 billion annually. This number is likely to skyrocket as property prices rise and more people relocate to locations where extreme weather events occur more frequently and with greater severity.
Australia’s severe susceptibility to climate effects is highlighted by the deadly Black Summer fires, a debilitating drought, and yet another major bleaching of the Great Barrier Reef.
According to Erwin Jackson, policy director of the Investor Group on Climate Change, Australia is very vulnerable to climate change’s physical effects, and the government alone will not be able to cover the costs.
He stated that the private sector would invest in resilience and adaptation measures if policy guidance was provided. That began with the government’s excellent reaction to the royal inquiry on bushfires and the establishment of a National Recovery and Resilience Agency, but he warned more was needed.
Climate Change in Pacific Region
The frequency of Pacific rainfall disruption events such as droughts and floods has already increased by 30% as a result of global warming, according to Australian Bureau of Meteorology (BOM) modeling and will increase by 90% by mid-century and 130 percent later in the century unless emissions are reduced.
As climate change wreaks havoc on Pacific weather, droughts and deluge rains are becoming more common. With record flames breaking out in Australia and throughout the world, fire seasons are becoming longer and hotter, increasing the frequency and severity of fire hazard days.
