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.
Heatwaves will be more frequent and long-lasting, causing droughts, global food shortages, migration, and increased spread of infectious diseases. Moreover, as the polar ice will melt, sea levels will rise substantially, affecting a large number of coastline cities and as many as 275 million of their inhabitants.
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.
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.
Lucas Zeppetello at Harvard University and his colleagues modelled a range of greenhouse gas emissions scenarios based on global population and economic growth by the end of the century. They found that global average temperature would rise between 2.1°C and 4.3°C by 2100.
Eventually humans will go extinct. At the most wildly optimistic estimate, our species will last perhaps another billion years but end when the expanding envelope of the sun swells outward and heats the planet to a Venus-like state. But a billion years is a long time.
The earth would become warmer, the average temperature will increase. There will be several new weather patterns and the sea levels would rise. Eventually humans would die out. If the insect population continues to decline, all birds that depend on insect for food will become extinct.
Civilisations could collapse by 2100. Despite only dealing with probabilities, scientists predict without a determined effort to reduce emissions, the globe will likely experience 4 degrees of warming by 2100. “That makes large parts of Australia and other continents uninhabitable,” Prof Flannery warns.
New research suggests that, if the planet keeps warming at current rates, much of the top third of Australia could soon be too hot for people to live in.
Australia's economic recovery is leading the world. More Australians are in work than ever before and the unemployment rate is now forecast to reach 3¾ per cent in 2022, the lowest rate in close to 50 years.
A UK study rated Tasmania one of the best places to survive a collapse in society. Scientists say Tasmania's climate, agricultural resources and electricity supply make it an ideal refuge should "things go pear-shaped"
Australia will need to triple the National Electricity Market's power capacity by 2030 to be on track for net zero by 2050 – requiring a rapid rollout of wind and solar power, transmission, storage, electric vehicles, and heat pumps as we replace our coal fleet, new research shows.
Current outlook for Australia
the time in drought will increase across southern Australia. snow depths will decline. extreme rainfall events will become more intense. sea levels will rise.
Africa and the Arab World will shape our future, while Europe and Asia will recede in their influence. By the end of the century, the world will be multipolar, with India, Nigeria, China, and the US the dominant powers. This will truly be a new world and one we should be preparing for today.”
Humans in the year 3000 will have a larger skull but, at the same time, a very small brain. "It's possible that we will develop thicker skulls, but if a scientific theory is to be believed, technology can also change the size of our brains," they write.
By most estimates, the Earth will be host to 11 billion humans by 2100, leaving little space for such for humans to live and thrive.
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.
According to a new Climate Council report, by 2040, summertime temperatures on hot days in Sydney and Melbourne will be approaching 50 degrees, making summer sport as it is played at present untenable.
El Niño in 2023 becoming more likely, which would result in dry, warm weather across eastern Australia. The first El Niño phase of the Pacific Ocean in eight years is becoming more likely in 2023, increasing the odds of drier and warmer weather across eastern Australia.
Absolutely. Australia is a fantastic place to live, even for foreigners. There aren't only advantages to living in Australia, but they outweigh the disadvantages. I love the climate, work-life balance, safety and the wide range of outdoor activities that I can enjoy every weekend.
Australia's unique ecosystems such as the Great Barrier Reef and many animal species are also at risk. Climate change also has diverse implications for Australia's economy, agriculture and public health. Projected impacts include more severe floods, droughts, and cyclones.
Population, society and the economy
Australia's population will increase by 50-100% by 2050. The proportion of the population living in the north and west is projected to increase at the expense of smaller southern states. Median age will increase from the 36.8 years of 2007 to between 41.9 and 45.2 years.
In the next 1,000 years, the amount of languages spoken on the planet are set to seriously diminish, and all that extra heat and UV radiation could see darker skin become an evolutionary advantage. And we're all set to get a whole lot taller and thinner, if we want to survive, that is.
By 2030, almost all countries will experience “extreme hot” weather every other year due mainly to greenhouse gas pollution by a handful of big emitters, according to a paper published Thursday by Communications Earth & Environment, reinforcing forecasts that the coming year will be one of the hottest on record.
Unless CO2 emissions drop significantly, global warming by 2500 will make the Amazon barren, the American Midwest tropical, and India too hot to live in, according to a team of international scientists.
