Climate Change And Agriculture In The United States
Climate change and agriculture are complexly related processes. In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector.Center for Climate and Energy Solutions. 2019. "Science and Impacts".https://www.c2es.org/site/assets/uploads/2019/09/science-and-impacts.pdf Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well.National Sustainable Agriculture Coalition. 2019. Agriculture and Climate Change: Policy Imperatives and Opportunities to Help Producers Meet the Challenge. Washington D.C. While agriculture plays a role in propelling climate change, it is also affected by the direct (increase in temperature, change in rainfall, flooding, drought) and secondary (weed, pest, disease pressure, infrastructure damage) consequences of climate change.USGCRP, 2017: ''Climate Science Special Report: Fou ...

Climate Change In The United States
Climate change in the United States has led to the country warming by 2.6°F (1.4°C) since 1970. Due to climate change, the climate of the United States is shifting in ways that are widespread and varied between regions. From 2010 to 2019, the United States experienced its hottest decade on record. Extreme weather events, invasive species, floods and droughts are increasing. Climate change's impacts on tropical cyclones and sea level rise also affects regions of the country. Cumulatively since 1850, the U.S. has emitted a larger share than any country of the greenhouse gases causing current climate change, with some 20% of the global total of carbon dioxide alone. Current US emissions per person are among the largest in the world.www.climatewatchdata.org at ''Calculation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Sequestration
Carbon sequestration is the process of storing carbon in a carbon pool. Carbon dioxide () is naturally captured from the atmosphere through biological, chemical, and physical processes. These changes can be accelerated through changes in land use and agricultural practices, such as converting crop land into land for non-crop fast growing plants. Artificial processes have been devised to produce similar effects, including large-scale, artificial capture and sequestration of industrially produced using subsurface saline aquifers, reservoirs, ocean water, aging oil fields, or other carbon sinks, bio-energy with carbon capture and storage, biochar, enhanced weathering, direct air capture and water capture when combined with storage. Forests, kelp beds, and other forms of plant life absorb carbon dioxide from the air as they grow, and bind it into biomass. However, these biological stores are considered volatile carbon sinks as the long-term sequestration cannot be guarant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Institute Of Food And Agriculture
The National Institute of Food and Agriculture (NIFA) is a U.S. federal government body whose creation was mandated in the Food, Conservation, and Energy Act of 2008. Its purpose is to consolidate all federally funded agricultural research, and it is subordinate to the Department of Agriculture. It replaced the Cooperative State Research, Education, and Extension Service in 2009. , Dionne Toombs has served as the Acting Director. The mission of the National Institute of Food and Agriculture (NIFA), an agency of the U.S. Department of Agriculture (USDA), is to stimulate and fund the research and technological innovations that will enhance American agriculture and make it more productive and environmentally sustainable while ensuring the economic viability of agriculture and production. The Institute was developed as a result of a task force chaired by William Henry Danforth and appointed by then- Secretary of Agriculture Ann Veneman. The Danforth Task Force recommended tha ...

Economic Research Service
The Economic Research Service (ERS) is a component of the United States Department of Agriculture (USDA) and a principal agency of the Federal Statistical System of the United States. It provides information and research on agriculture and economics. History The first USDA agency formally tasked with data collection was the Division of Statistics, created in 1863, one year after the USDA itself was created.Panel to Study the Research Program of the Economic Research Service, Sowing Seeds of Change: Informing Public Policy in the Economic Research Service of USDA', Committee on National Statistics, Commission on Behavioral and Social Sciences and Education, National Research Council (John F. Gewek et al., eds. 1999). By 1902, a Division of Foreign Markets had been created, and the following year, that division was merged with the Division of Statistics to form the Bureau of Statistics. In 1914, the bureau was renamed the Bureau of Crop Estimates, and in 1921 this bureau merged wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Climate Change Adaptation
Climate change adaptation is the process of adjusting to current or expected effects of climate change.IPCC, 2022Annex II: Glossary öller, V., R. van Diemen, J.B.R. Matthews, C. Méndez, S. Semenov, J.S. Fuglestvedt, A. Reisinger (eds.) InClimate Change 2022: Impacts, Adaptation and Vulnerability.

Climate Change Denial
Climate change denial, or global warming denial, is Denial (Freud), denial, dismissal, or doubt that contradicts the scientific consensus on climate change, including the extent to which it is Attribution of recent climate change, caused by humans, its Effects of global warming, effects on nature and human society, or the potential of adaptation to global warming by human actions. Many who deny, dismiss, or hold doubt about the scientific consensus on Anthropogenic hazard, anthropogenic global warming self-label as "climate change skeptics", which several scientists have noted is misnomer, an inaccurate description. Climate change denial can also be implicit when individuals or social groups accept the science but fail to come to terms with it or to translate their acceptance into action. Several social science studies have analyzed these positions as forms of denial or denialism,: "There is debate over which term is most appropriate ... Those involved in challenging climate ...

Soil Health
Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components (living and non-living) that belong together, as in microbiota, plants and animals. It is possible that a soil can be healthy in terms of eco-system functioning but not necessarily serve crop production or human nutrition directly, hence the scientific debate on terms and measurements. Soil health testing is pursued as an assessment of this status but tends to be confined largely to agronomic objectives, for obvious reasons. Soil health depends on soil biodiversity (with a robust soil biota), and it can be improved via soil management, especially by care to keep protective living covers on the soil and by natural (carbon-containing) soil amendments. Inorganic fertilizers do not necessarily damage soil health if 1) used at appropriate and not excessive rates and 2) if the ...

Greenhouse Gas
A greenhouse gas (GHG or GhG) is a gas that absorbs and emits radiant energy within the thermal infrared range, causing the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor (), carbon dioxide (), methane (), nitrous oxide (), and ozone (). Without greenhouse gases, the average temperature of Earth's surface would be about , rather than the present average of . The atmospheres of Venus, Mars and Titan also contain greenhouse gases. Human activities since the beginning of the Industrial Revolution (around 1750) have increased the atmospheric concentration of carbon dioxide by over 50%, from 280 ppm in 1750 to 421 ppm in 2022. The last time the atmospheric concentration of carbon dioxide was this high was over 3 million years ago. This increase has occurred despite the absorption of more than half of the emissions by various natural carbon sinks in the carbon cycle. At current greenhouse gas emission rates, temperatures co ...

Effects Of Climate Change
The effects of climate change impact the physical environment, ecosystems and human societies. The environmental effects of climate change are broad and far-reaching. They affect the water cycle, oceans, sea and land ice ( glaciers), sea level, as well as weather and climate extreme events. The changes in climate are not uniform across the Earth. In particular, most land areas have warmed faster than most ocean areas, and the Arctic is warming faster than most other regions. The regional changes vary: at high latitudes it is the average temperature that is increasing, while for the oceans and tropics it is in particular the rainfall and the water cycle where changes are observed. The magnitude of future impacts of climate change can be reduced by climate change mitigation and adaptation. Climate change has degraded land by raising temperatures, drying soils and increasing wildfire risk. Recent warming has strongly affected natural biological systems. Species worldwide ...
