Africa's share of global population is projected to grow from 17% in 2020 to 25% in 2050 and 38% by 2100, while the share of Asia will fall from 60% in 2020 to 55% in 2050 and 45% in 2100. [ 5 ] [ 6 ] The strong growth of the African population will happen regardless of the rate of decrease of fertility, because of the high proportion of young ...
Earth 2100 is a television program and a Science fiction documentary film that was presented by ABC on June 2, 2009, aired on the History Channel in January 2010, and was shown throughout the year. The two-hour special, which Bob Woodruff hosted, looked at what "a worst-case" future might entail if people do nothing about current or impending ...
Many studies have tried to estimate the world's sustainable population for humans, that is, the maximum population the world can host. [5] A 2004 meta-analysis of 69 such studies from 1694 until 2001 found the average predicted maximum number of people the Earth would ever have was 7.7 billion people, with lower and upper meta-bounds at 0.65 and 9.8 billion people, respectively.
Even in the best-case scenario, where the temperature increase is limited to 1.5C, around half of the glaciers will disappear, experts predict.
According to an MIT press release, Daniel Rothman has found a threshold that, if exceeded, would lead to an unstable environment and "mass extinction."
Sea-level rise by 2100 is likely to be from half to one metre, but two to five metres is not ruled out, as ice sheet instability processes are still poorly understood. [ 21 ] The report quantifies climate sensitivity as between 2.5 °C (4.5 °F) and 4.0 °C (7.2 °F) for each doubling of carbon dioxide in the atmosphere , [ 7 ] while the best ...
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity.
A Direct Hit! The impressive #solarstorm launched in the Earth-strike zone has been modeled by NASA. The storm is predicted to hit Earth by midday December 1. Along with two earlier storms already ...
