Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
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 ...
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 ...
Global change in a societal context encompasses social, cultural, technological, political, economic and legal change. Terms closely related to global change and society are globalization and global integration. Globalization began with long-distance trade and urbanism. The first record of long distance trading routes is in the third millennium BC.
Climate change impacts small island ecosystems in ways that have a detrimental effect on public health. In island nations, changes in sea levels, temperature, and humidity may increase the prevalence of mosquitoes and diseases carried by them such as malaria and Zika virus. Rising sea levels and severe weather such as flooding and droughts may ...
Examples of such reports include or the 2004 Arctic Climate Impact Assessment from the International Arctic Science Committee and the governments of the Arctic Council, [25] [26] or the United States' National Climate Assessment, which has been released periodically since 2000 under the auspices of the United States Global Change Research Program.
Estimates of the economic impacts from climate change in future years are most often measured as percent global GDP change, relative to GDP without additional climate change. [10]: 2495 The 2022 IPCC report compared the latest estimates of many modelling and meta-analysis studies. It found wide variety in the results.
Examples include variability in ocean basins such as the Pacific decadal oscillation and Atlantic multidecadal oscillation. Climate variability can also result from external forcing, when events outside of the climate system's components produce changes within the system. Examples include changes in solar output and volcanism.
