There have been debates on the best responses to slow global warming, and their timing. The debates are around the specific actions for climate change mitigation and climate change adaptation, or climate action in general. See for example: Economic analysis of climate change; Climate change denial#Delaying climate change mitigation measures
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 ...
The Geneva-based agency, in a “State of the Global Climate” report released Tuesday, ratcheted up co UN weather agency issues 'red alert' on climate change after record heat, ice-melt ...
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 ...
The problematic perception of climate change as simply a “global” issue: Climate change initiatives and governance approaches have tended to be driven from a global scale. While the development of international agreements has witnessed a progressive step of global political action, this globally-led governance of climate change issue may be ...
The first World Climate Conference in 1979 framed climate change as a global political issue, giving way to similar conferences in 1985, 1987, and 1988. [20] In 1985, the Advisory Group on Greenhouse Gases (AGGG) was formed to offer international policy recommendations regarding climate change and global warming. [20]
However, this reduction was a result of reduced economic activity, not the decarbonization of the economy required to respond to climate change. [22] The Global Carbon Project estimated that global daily CO 2 emissions may have been reduced by 17% during the most intense periods of COVID-19 shutdowns, but the WMO's Greenhouse Gas Bulletin ...
