Archaeologists are increasingly under pressure to demonstrate that their work has impact beyond the discipline. This has prompted environmental archaeologists to argue that an understanding of past environmental changes is essential to model future outcomes in areas such as climate change, land cover change, soil health and food security.

These historical impacts of climate change can improve human life and cause societies to flourish, or can be instrumental in civilization's societal collapse. The study seeks to define periods in human history where temperature or precipitation varied from what is observed in the present day.
As anthropogenic climate change affects our environment, projections show that there will be changes in rainfall with increased drought and desertification, increases in intensity and frequency of rainfall, increases in temperature (winter and summer), increases in both the temperature and frequency of heatwaves, rising sea levels, and warmer ...
Today, archaeologists use faunal remains as a guide to the environment. It helps archaeologists understand whether the fauna were present naturally or through activities of carnivores or people. [4] Archaeologists deal with macrofauna and microfauna. Microfauna are better indicators of climate and environmental change than larger species.
Climate projections also show that changes in rainfall (intensity and frequency), increases in temperature and frequency of heatwaves, rising sea levels and groundwater fluctuations, warmer seas and ocean acidification will also result in changes to flora and fauna, ground conditions (on and below the surface) will affect archaeological ...
Climate change poses a threat to US national parks like Yellowstone. Warmer temperatures and extreme weather impact both ecosystems and visitors. Advocates hope witnessing changes to the parks ...
Copeland Report – for the U.S. government, completed in 1933; Copenhagen Diagnosis – written by twenty-six climate scientists from eight countries; Dioxin Reassessment Report – by the United States Environmental Protection Agency; Environmental Impact of the Big Cypress Swamp Jetport ("Leopold Report") – United States Department of the ...
Climate change is having considerable impacts on the environment and society of the United States. This includes implications for agriculture, the economy (especially the affordability and availability of insurance), human health, and indigenous peoples, and it is seen as a national security threat.
