By 2070, Earth will likely face intensified climate impacts, with billions potentially living in extreme heat zones, leading to significant human-wildlife overlap and increased conflict as habitats shift, though some optimistic views foresee technological solutions and greater environmental awareness driving positive change, with human-animal interactions increasing across much of the planet, raising risks of disease and habitat loss.
A third of the world's population could live in a climate similar to the Sahara in just 50 years, according to a study published in PNAS in 2020. That means 3.5 billion people could live with average temperatures in the mid-80s, “outside of humanity's comfort zone” by 2070.
The survey also asked respondents which state or territory will be the safest place to live as the climate changes. Tasmania is the clear winner, with two in five Australians (41 per cent) choosing it, with other states falling well behind.

China, India, and the United States will emerge as the world's three largest economies in 2050, with a total real U.S. dollar GDP of 70 percent more than the GDP of all the other G20 countries combined.
