The warming will likely cause a number of key trends: Accelerated sea level rise and worsening coastal erosion. Increased weather intensity including Category 6 cyclones. More frequent and extreme bushfires. A greater chance of extreme flood events.
By 2050, the Thredbo area in the NSW Snowy Mountains will have a longer and hotter winter in store, with temperature increases of 4.8°C in the next few decades. And Sydney's western suburbs, urban areas like Penrith are set to experience 86 additional days of temperatures higher than 30°C.
Rainfall is expected to become heavier and more infrequent, as well as more common in summer rather than in winter. Australia's annual average temperatures are projected to increase 0.4–2.0 °C above 1990 levels by the year 2030, and 1–6 °C by 2070.
The report provides a comprehensive study of the challenges that Australia will face over the next 40 years, including an ageing population, escalating pressures on the health system, and the environmental and economic challenges of climate change.
Seasons Change
Instead of winter, the researchers believe Australians will experience spring, autumn, and a longer season they're calling "new summer." During this new season, temperatures will consistently peak above 40 degrees Celsius (104 degrees Fahrenheit) for sustained periods of time, based on predictions.
Three major economic centres are set to become uninhabitable by the end of the century, with global temperatures on track to warm by 2.7C. Darwin, Broome and Port Hedland are predicted to be pushed outside the “human climate niche” — that is, the temperature and humidity conditions in which humans can survive.
The report stated there was “very high confidence” that temperatures would rise across Australia throughout the century, with the average annual temperature set to be up to 1.3C warmer in 2030 compared with the average experienced between 1986 and 2005.
Higher emissions cause greater warming. Winter rainfall in southern Australia is likely to decline. Most of the country is likely to experience more extreme daily rainfall. Sea levels are projected to increase at a faster rate than during the last century.
hot days will become hotter and more frequent. the time in drought will increase across southern Australia. snow depths will decline. extreme rainfall events will become more intense.
Government related predictions to impact Australia in 2025 include: All Australian citizens now have a single digital ID, which allows them to secure their personal information and easily access government services online. Likelihood: 60%link. All federal government services are now available online.
While many people have already moved to Tasmania to escape the heat in other states, some doomsday preppers are weighing up the island state as a post-apocalyptic option. Tasmania scored highly in the report in terms of its climate, electricity supply, agricultural resources and population density.
The southern coast, which includes Adelaide, Melbourne and Sydney, has the best climate by far, with mild winters (June to August) between 41°F and 50°F (5°C and 10°C) and warm summers (December to February) between 77°F and 86°F (25°C and 30°C).
Australia's national climate projections at Climate change in Australia indicate that over coming decades Australia will experience: Further increase in temperatures, with more extremely hot days and fewer extremely cool days. Ongoing sea level rise. Further warming and acidification of the oceans around Australia.
With the world heating up it makes sense to head south for cooler climates — which is why many are looking to the island state of Tasmania for sustainable buying.
Future Hot Spots
But climate models tell us certain regions are likely to exceed those temperatures in the next 30-to-50 years. The most vulnerable areas include South Asia, the Persian Gulf, and the Red Sea by around 2050; and Eastern China, parts of Southeast Asia, and Brazil by 2070.
The mobile-friendly MyClimate 2050 tool shows almost all areas across Australia will experience longer and hotter summers, with temperatures increasing by an average of 2.32°C.
Victoria, New South Wales and Queensland are among the top 10% of global jurisdictions most at risk from the physical impacts of climate change, according to a new report ranking the physical climate risk of every state, province and territory in the world released today by The Cross Dependency Initiative (XDI).
Chad. Chad ranks as the world's most climate-vulnerable country on the Notre Dame-Global Adaptation Initiative Index, which examines a country's exposure, sensitivity and capacity to adapt to the negative effects of climate change.
At 3°C of global warming, many of Australia's ecological systems would be unrecognisable. The decline of Australia's natural resources would accelerate through changing distributions or loss of thousands of species and disrupted ecological processes such as habitat maintenance.
The World Health Organisation projects that between 2030 and 2050, climate change impacts will cause 250,000 more deaths globally each year, mainly from malnutrition, malaria, diarrhea, and heat stress.
Australia's temperatures are rising more rapidly than the global average and despite years like 2022 when a La Niña weather pattern generates a period of relative cool, according to an IEA assessment that warns of fallout on energy systems.
The wildlife we love and their habitat will be destroyed, leading to mass species extinction. Superstorms, drought, and heat waves would become increasingly common and more extreme, leading to major health crises and illness. Agricultural production would plummet, likely leading to global food shortages and famine.
They predict that in three decades, more than 100 million Americans will live in an “extreme heat belt” where at least one day a year, the heat index temperature will exceed 125° Fahrenheit (52° Celsius) — the top level of the National Weather Service's heat index, or the extreme danger level.
2100: Either uninhabitable or beginning to repair
Over the coming two decades, extreme weather is set to disrupt society with increasingly severe bushfires, drought and storms. The good news is by the end of the century, living on Earth could actually be more pleasant than it is today.
Maximum temperatures are expected to be higher than average over most of Australia this winter, particularly during the second half of the season if El Niño and a positive IOD become entrenched.
