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 second part of the report, a contribution of working group II (WGII), was published on 28 February 2022. Entitled Climate Change 2022: Impacts, Adaptation & Vulnerability, the full report is 3675 pages, plus a 37-page summary for policymakers. [29] It contains information on the impacts of climate change on nature and human activity. [30]
Through its Committee on the Science of Climate Change in 2001, the United States National Research Council published Climate Change Science: An Analysis of Some Key Questions. This report explicitly endorses the IPCC view of attribution of recent climate change as representing the view of the scientific community: [5]
2 November: a study published in Oxford Open Climate Change (co-author: James E. Hansen) projected that the recent decline of aerosol emissions should increase the global warming rate of 0.18 °C per decade (1970–2010) to at least 0.27 °C per decade, so that "under the present geopolitical approach to GHG emissions", warming will exceed 1.5 ...
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 ...
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 ...
Climate change is one of the single biggest challenges facing development, and we need to assume the moral responsibility to take action on behalf of future generations, especially the poorest. [74] A World Bank report into climate change in 2012 noted that (p. xiii) "even with the current mitigation commitments and pledges fully implemented ...
7 August: a study published in PLOS One found that even a single repetition of a claim was sufficient to increase the perceived truth of both climate science-aligned claims and climate change skeptic/denial claims—"highlighting the insidious effect of repetition". [95] This effect was found even among climate science endorsers. [95]
