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 ...
The IPCC published the Working Group I report, Climate Change 2021: The Physical Science Basis, in August 2021. [12] It confirms that the climate is already changing in every region. Many of these changes have not been seen in thousands of years. Many of them such as sea-level rise are irreversible over hundreds of thousands of years. Strong ...
From ancient times, people suspected that the climate of a region could change over the course of centuries. For example, Theophrastus, a pupil of Ancient Greek philosopher Aristotle in the 4th century BC, told how the draining of marshes had made a particular locality more susceptible to freezing, and speculated that lands became warmer when the clearing of forests exposed them to sunlight.
It was endorsed by "more than 110 physical and biological scientists studying climate and climate impacts about the role of physical sciences research." [ 101 ] Another called for "balance in research and assessment of solar radiation modification" and was endorsed by about 150 experts, mostly scientists.
