Hazard Breakdown

Flood, bushfire, heat, coastal and storm exposure are all assessed in this area. The score that matters is the property's own: a ClimateNest report scores the address across eight hazards, with insurance and value projections to 2050.

Climate Hazard Breakdown for Toronto

Flood

Toronto is located near Lake Macquarie and several creeks, making it susceptible to flooding from heavy rainfall and rising lake levels. Climate change is expected to increase the intensity of rainfall events, exacerbating flood risk.

Key drivers:

·Increased rainfall intensity
·Rising lake levels

Bushfire

While not immediately surrounded by dense bushland, Toronto has some bushfire risk due to nearby vegetation and potential for ember attacks. Drier conditions and higher temperatures associated with climate change will increase the likelihood of bushfires.

Key drivers:

·Increased temperatures
·Drier conditions

Heat

Toronto experiences hot summers, and climate change is projected to increase the frequency and intensity of heatwaves. This poses a risk to vulnerable populations, such as the elderly and those with chronic health conditions.

Key drivers:

·Increased temperatures
·More frequent heatwaves

Coastal

Located on the shores of Lake Macquarie, Toronto faces potential risks from rising lake levels and increased storm surges due to climate change. This could lead to erosion and inundation of low-lying areas.

Key drivers:

·Rising lake levels
·Increased storm surges

4.Obtain a building inspection report.

How the region's climate is projected to change

Regional projections, not a forecast for this street. Figures are from the WA Department of Water and Environmental Regulation's climate projections for the South Western Flatlands region, which draws on CSIRO and Bureau of Meteorology modelling.

Temperature

+0.5 to 1.1°C by 2030

Above the 1986–2005 climate, on all emissions scenarios. By 2090, 1.2 to 2.0°C under intermediate emissions or 2.6 to 4.0°C under high emissions.

Rainfall

Winter rain down up to 15% by 2030

The South West has been drying since 1970, and the decline has been larger than anywhere else in Australia. Heavy rainfall events are projected to become more intense even as totals fall.

Fire weather

Harsher, magnitude uncertain

High confidence that fire weather becomes harsher, low confidence in the size of the change, because it depends heavily on summer rainfall.

Sea level

+0.12 m by 2030

At the Fremantle gauge, range 0.07 to 0.16 m. Very high confidence that sea levels continue to rise through the century.

About Toronto's Climate Risk Profile

Toronto, situated on the western shore of Lake Macquarie in New South Wales, is a suburb that will experience notable impacts from climate change. The primary concerns for Toronto are increased flooding due to more intense rainfall and rising lake levels, more frequent and severe heatwaves, and potential impacts from rising lake levels and storm surges.

The risk of flooding is elevated due to Toronto's location near Lake Macquarie and several creeks. Climate change is projected to increase the intensity of rainfall events, leading to more frequent and severe flooding. This can damage property, disrupt infrastructure, and pose risks to human safety.

Heatwaves are another significant concern for Toronto. As temperatures rise, the risk of heatstroke and other heat-related illnesses increases, particularly for vulnerable populations. The urban environment can exacerbate the effects of heatwaves due to the urban heat island effect.

Rising lake levels and storm surges pose a threat to low-lying areas along the Lake Macquarie shoreline. This can lead to erosion, inundation, and damage to infrastructure and property. The impacts of these coastal hazards are expected to worsen as climate change progresses.

Addressing these climate risks requires a combination of adaptation and mitigation strategies. Adaptation measures include improving drainage infrastructure, implementing early warning systems for heatwaves and floods, and protecting coastal areas from erosion. Mitigation efforts involve reducing greenhouse gas emissions to slow the pace of climate change.

Suburb pages describe the local picture. The address-level assessment, with its data sources and its dollar projections, is in the ClimateNest report.
