September: stating that climate change is already "an important threat", with "climate change and severe weather" endangering 34% of species, BirdLife International's State of the World's Birds 2022 reported that 49% of bird species worldwide have declining populations (only 6% are increasing).
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 ...
The Climate Change Performance Index (CCPI) is a scoring system designed by the German environmental and development organisation Germanwatch e.V. to enhance transparency in international climate politics.
In the same recent EY survey, 34% of respondents planned to spend more to address climate change in 2023, down from 61% in 2022. Despite these obstacles, leaders cannot let a desire for perfection ...
The second part of the report, a contribution of working group II (WGII), was published on 28 February 2022.

[29] It contains information on the impacts of climate change on nature and human activity. [30]
A study published in Science Advances in 2022 stated that climate-caused changes in atmospheric rivers affecting California had already doubled the likelihood of megafloods—which can involve 100 inches (250 cm) of rain and/or melted snow in the mountains per month, or 25 to 34 feet (7.6 to 10.4 m) of snow in the Sierra Nevada—and runoff in ...
In 2004, the geologist and historian of science Naomi Oreskes analyzed the abstracts of 928 scientific papers on "global climate change" published between 1993 and 2003. 75% had either explicitly expressed support for the scientific consensus on anthropogenic climate change, or had accepted it as a given and were focused on evaluating its ...
Almost no other ecosystem is as vulnerable to climate change as coral reefs. Updated 2022 estimates show that even at a global average increase of 1.5 °C (2.7 °F) over pre-industrial temperatures, only 0.2% of the world's coral reefs would still be able to withstand marine heatwaves, as opposed to 84% being able to do so now, with the figure ...
