[211] [212] A study summarising a number of impact studies of climate change on agriculture in Latin America indicated that wheat is expected to decrease in Brazil, Argentina and Uruguay. [212] Livestock, which is the main agricultural product for parts of Argentina, Uruguay, southern Brazil, Venezuela, and Colombia is likely to be reduced.
Air pollution caused by agriculture through land use changes and animal agriculture practices have an outsized impact on climate change. Addressing these concerns was a central part of the IPCC Special Report on Climate Change and Land [48] as well as in the 2024 UNEP Actions on Air Quality report. [49]
A leader at the Union of Concerned Scientists commented, "It is refreshing to see the USDA under Secretary Perdue—who has previously denied the reality of climate change—acknowledging that agriculture is a contributor to climate change, can also be part of the solution, and must adapt in any case." [12]
[64] [65] Climate change poses unprecedented challenges to U.S. agriculture due to the sensitivity of agricultural productivity and costs to changing climate conditions. [66] Rural communities dependent on agriculture are particularly vulnerable to climate change threats. [63]
At least 72% of Chinese, American and European respondents to a 2020−2021 European Investment Bank climate survey stated that climate change had an impact on everyday life. The Fifth National Climate Assessment states that climate change impacts communities over all the territory of the United States. The impacts differ from state to state.
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 ...
[44]: 231 Detailed long-term records of both livestock diseases and various agricultural interventions in Europe mean that demonstrating the role of climate change in the increased helminth burden in livestock is actually easier than attributing the impact of climate change on diseases which affect humans. [44]: 231
Land-use change can be a factor in CO 2 (carbon dioxide) atmospheric concentration, and is thus a contributor to global climate change. [14] IPCC estimates that land-use change (e.g. conversion of forest into agricultural land) contributes a net 1.6 ± 0.8 Gt carbon per year to the atmosphere.
