Antarctica is undoubtedly one of the planet's most
Deserts. A desert is known for its extreme temperatures and extremely dry climate. The type of species that live in this area have adapted to these harsh conditions over years and years.
Araouane may well be the hottest inhabited place on Earth. Surrounded by barren desert, pounded by hideous sandstorms known as 'harmattan', and no rain to speak of, the 300 or so inhabitants of this village can bake in average summer temperatures of 46ºC.
The Australian Outback
Arid weather, fierce sun and infertile soil keep the population low in this desert, which spans most of the continent of Australia.
However, harsh environments, such as a very hot climate, limited water and infertile land, make it more difficult for people to survive. We are also affected by major environmental events such as earthquakes, floods and drought that damage homes, property and agriculture.
Major classes of extreme environments encompass acidic (pH < 5), alkaline (pH > 9), hypersaline (salinity > 35‰), pressurized (> 0.1 MPa), hot (> 40°C), cold (<5°C), dry (aw < 0.80), and high-radiation environments.
Extreme environments are inhospitable to most life forms. But some organisms, including humans, have adapted to survive or even flourish in these conditions. Where are these extreme environments? The high-altitude Andes, Arctic sea ice, high-pressure depths of the sea, and sunless caves are four examples.
Tasmania has been named the unhealthiest state in the country with the highest stress levels, body mass index (BMI), blood pressure and smoking rates.
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.
Australia is a land of extremes with temperatures ranging from highs of 40°C in the central desert regions to below freezing in the higher regions of the country's southeast. Sometimes these extremes can be experienced on a single day.
People often point to a study published in 2010 that estimated that a wet-bulb temperature of 35 C – equal to 95 F at 100 percent humidity, or 115 F at 50 percent humidity – would be the upper limit of safety, beyond which the human body can no longer cool itself by evaporating sweat from the surface of the body to ...
Science proves 'sunny and +23°C (73°F)' is perfect for our health. Surveys of weather preferences show that, for Europeans, the most preferred temperature range is 20 to 26°C, within which 22 to 23°C is simply ideal.
"The biodiversity crisis -- i.e. the rapid loss of species and the rapid degradation of ecosystems -- is probably a greater threat than global climate change to the stability and prosperous future of humankind on Earth.
Normally, the rule of threes contains the following: You can survive three minutes without breathable air (unconsciousness), or in icy water. You can survive three hours in a harsh environment (extreme heat or cold). You can survive three days without drinkable water.
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.
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.
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.
Tasmania. Tasmania was named the 'bogan capital of Australia' with Taswegians earning four spots in the final. On the island of Tasmania, half the population has literacy and/or numeracy difficulties, and the unemployment rate is higher than it is in mainland Australia.
South Australia has been crowned Australia's most considerate state! South Australians have been found to be the most likely to consider other people's needs, according to the Helga's Kindness Index, a first-of-its-kind report examining the state of kindness in the country.
“Queensland's known as the Sunshine State. All those rays and the laid-back lifestyle might be among the reasons why it's Australia's happiest state,” Bayliss said.
While the population can expect to live longer lives on average, the human lifespan might have a cap. Scientists believe that the human lifespan could be anywhere from 120-150 years long, but not longer than that, due to accumulating hallmarks of aging and chronic disease.
Earth's capacity
Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.
Our planet might remain habitable for roughly a billion years. If we survive as long as the Earth stays habitable, and based on the scenario above, this would be a future in which 125 quadrillion children will be born. A quadrillion is a 1 followed by 15 zeros: 1,000,000,000,000,000.
Humans are essentially tropical animals and are not equipped to deal with even mild cold. That we can live in cold climates is a result of behavioural adaptations such as wearing appropriate clothing and building shelters. Successfully surviving cold requires two simultaneous events.
People may choose to live and work in extreme places for a variety of reasons. Some people are drawn to the challenge and adventure of living in remote or difficult-to-access locations, while others may be motivated by the opportunity to work in specialized fields such as scientific research or resource extraction.
