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 ...
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.
It has since been set backward 8 times and forward 18 times. The farthest time from midnight was 17 minutes in 1991, and the closest is 89 seconds, set in January 2025. [5] The Clock was moved to 150 seconds (2 minutes, 30 seconds) in 2017, then forward to 2 minutes to midnight in 2018, and left unchanged in 2019. [6]
Last year was the warmest year on record, and the first with a global average temperature of more than 1.5 degrees Celsius above the pre-industrial levels. At current rates of warming, 2 degrees ...

By the year 2100, the median population projection is at 11 billion people, while the maximum population projection is close to 16 billion people. The lowest projection for 2100 is around 7 billion, and this decline from present levels is primarily attributed to "rapid development and investment in education", with those projections associated ...
The symbolic clock now reads 89 seconds to midnight after advancing one second since last year's reset. It is now the closest to midnight since the introduction of the clock in 1947.
Climate endgame is a term used to refer to the risk of societal collapse and potential human extinction due to the effects of climate change. [2] The usage of the term seeks to improve risk management by putting a higher priority on worst-case scenarios , to "galvanise action, improve resilience, and inform policy ".
