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 ...
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 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 ...
[1] [6] [7] In a letter sent to Senator Chuck Hagel, he cited increasing energy costs, [8] [9] and an "incomplete state of scientific knowledge of the causes of, and solutions to, global climate change and the lack of commercially available technologies for removing and storing carbon dioxide". [6]
According to the U.S. Climate Resilience Toolkit, a government funded website assessing U.S. global warming risks, "models predict that the [Northeast] region could see a warming of 4.5°F to 10 ...
Climate change mitigation policies can have a large and complex impact on the socio-economic status of individuals and countries This can be both positive and negative. [300] It is important to design policies well and make them inclusive. Otherwise climate change mitigation measures can impose higher financial costs on poor households. [301]
For example, climatologist Kevin E. Trenberth has published widely on the topic of climate variability and has exposed flaws in the publications of other scientists. [6] [7] [8] For past debates and controversies on scientific details see for example: History of climate change science#Discredited theories and reconciled apparent discrepancies ...
The first chapter describes the expected effects of climate change with one degree Celsius (1 °C) increase in average global temperature since pre-industrial times.. The second chapter describes the effects of two degrees average temperature and so forth until Chapter 6 which shows the expected effects of an increase of six Celsius degrees (6 °C) average global temperature.
