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 ...
The inscription '1.5 °' at Neustädter Elbufer in Dresden for adhering to the 1.5-degree target by Fridays for Future (2022). The 1.5-degree target (also known as the 1.5-degree limit) is the climate goal of limiting the man-made global temperature increase caused by the greenhouse effect to 1.5 °C on a 20-year average, calculated from the beginning of industrialization to the year 2100.

Global warming of 1.5 °C and 2 °C will be exceeded during the 21st century unless deep reductions in CO2 and other greenhouse gas emissions occur in the coming decades. [B.3] Continued global warming is projected to further intensify the global water cycle, including its variability, global monsoon precipitation and the severity of wet and ...
Climate drawdown refers to the future point in time when levels of greenhouse gas concentrations in the atmosphere stop climbing and start to steadily decline. [1] Drawdown is a milestone in reversing climate change and eventually reducing global average temperatures. [2]
Due to global warming and increased glacier melt, thermohaline circulation patterns may be altered by increasing amounts of freshwater released into oceans and, therefore, changing ocean salinity. Thermohaline circulation is responsible for bringing up cold, nutrient-rich water from the depths of the ocean, a process known as upwelling .
The oil and gas sector, one of the major emitters of planet-warming gases, will need a rapid and substantial overhaul for the world to avoid even worse extreme weather events fueled by human ...
The term "net zero" gained popularity after the Intergovernmental Panel on Climate Change published its Special Report on Global Warming of 1.5 °C (SR15) in 2018, this report stated that "Reaching and sustaining net zero global anthropogenic [human-caused] CO 2 emissions and declining net non-CO 2 radiative forcing would halt anthropogenic ...
It warned that greenhouse gas emissions must peak before 2025 at the latest and decline 43% by 2030 to have a good chance of limiting global warming to 1.5 °C (2.7 °F). [ 28 ] [ 29 ] Or in the words of Secretary-General of the United Nations António Guterres : "Main emitters must drastically cut emissions starting this year".
