The hot, dry and windy conditions that preceded the fires were about 35% more likely because of human-caused global warming, according to a new report from the World Weather Attribution group ...
No One Is Too Small to Make a Difference is a book by climate activist Greta Thunberg. It was originally published on 30 May 2019. It was originally published on 30 May 2019. It consists of a collection of eleven speeches which she has written and presented about global warming and the climate crisis .
Scientific consensus on causation: Academic studies of scientific agreement on human-caused global warming among climate experts (2010–2015) reflect that the level of consensus correlates with expertise in climate science. A 2019 study found scientific consensus to be at 100%, and a 2021 study concluded that consensus exceeded 99%.
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 ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [28]
The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the ...
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 ...
22 July publication: A review conducted under the World Climate Research Programme (WCRP) projected climate sensitivity—the range of global warming to be expected from a doubling of CO 2 concentration—to be 2.6—3.9 °C (4.7—7.0 °F), narrower than longstanding (1979+) estimates of about 1.5—4.5 °C (2.7—8.1 °F).
