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.

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 ...
According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The original climate spiral was published on 9 May 2016 by British climate scientist Ed Hawkins to portray global average temperature anomaly (change) since 1850. [6] The visualization graphic has since been expanded to represent other time-varying quantities such as atmospheric CO 2 concentration, [ 3 ] carbon budget , [ 3 ] and arctic sea ice ...
1.5 °C is an important threshold for many climate impacts, as shown by the Special Report on Global Warming of 1.5 °C. Every increment to global temperature is expected to increase weather extremes, such as heat waves and extreme precipitation events. There is also the risk of irreversible ice sheet loss.
26 May: an article published in the Proceedings of the National Academy of Sciences projected that under RCP 8.5 ("business as usual" scenario), the temperature experienced by an average human will change more in coming decades than over the past six millennia; the mean human-experienced temperature rise by 2070 will amount to an estimated 7.5 ...
Its full title is "Global Warming of 1.5 °C, an IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty".
