A high obliquity would probably result in dramatic changes in the climate and may destroy the planet's habitability. [41] When the axial tilt of the Earth exceeds 54°, the yearly insolation at the equator is less than that at the poles. The planet could remain at an obliquity of 60° to 90° for periods as long as 10 million years.
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
A climate apocalypse is a term used to denote a predicted scenario involving the global collapse of human civilization due to climate change. Such collapse could theoretically arrive through a set of interrelated concurrent factors such as famine, extreme weather , war and conflict, and disease. [ 1 ]
Scientists warn that if carbon dioxide and other greenhouse gas emissions continue to rise at their current rates, Earth’s temperatures could increase dramatically in future decades, leading to catastrophic and irreversible climate change. The 10 largest emitters produced about 26.4 gigatons of carbon dioxide in 2013.
The Climate Clock is a graphic to demonstrate how quickly the planet is approaching 1.5 °C of global warming, given current emissions trends. [1] It also shows the amount of CO 2 already emitted, and the global warming to date.

As a result the UN Framework Convention on Climate Change predicts a likely increase between 2.1 and 2.9 °C in temperature by 2100, exceeding the 2 °C climate target. [9] Some scientists suggest that the development of decarbonization technologies may offer a way to reverse the accumulation of CO 2 in the atmosphere.
