3.5–4.5 billion The Sun's luminosity will have increased by 35–40%, causing all water currently present in lakes and oceans to evaporate, if it had not done so earlier. The greenhouse effect caused by the massive, water-rich atmosphere will result in Earth's surface temperature rising to 1,400 K (1,130 °C; 2,060 °F), which is hot enough ...
The green, orange and yellow lines indicate how surface temperatures will likely respond if leading carbon emitters begin to reduce reliance on fossil fuels. Without immediate curbs, temperatures are set to follow the red track, and increase between 3.2 and 5.4 degrees Celsius by 2100. The green line shows how we can minimize warming if ...
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 ...
A year has about 365.24 solar days but 366.24 sidereal days. Therefore, there is one fewer solar day per year than there are sidereal days, similar to an observation of the coin rotation paradox. [5] This makes a sidereal day approximately 365.24 / 366.24 times the length of the 24-hour solar day.
In a 2024 survey, 76.3% of responding IPCC lead authors and review editors projected at least 2.5 °C of global warming by 2100; only 5.79% forecast warming of 1.5 °C or less. [98] January: the World Economic Forum projected that, by 2050, directly and indirectly, climate change will cause 14.5 million deaths and $12.5 trillion in economic losses.

[18] [19] Life on land took 30 million years to recover. [20] The Carboniferous Rainforest Collapse occurred 300 million years ago, at which time tropical rainforests were devastated by climate change. The cooler, drier climate had a severe effect on the biodiversity of amphibians, the primary form of vertebrate life on land. [3]
