Modeling impacts of mining activity-induced landscape change on local climate
Summary
Coal mining significantly impacts local temperatures, especially in mining areas, causing warming. Land use changes like conversion to water bodies cool regions, while urbanization increases temperatures by altering energy transfer processes.
Area of Science:
- Environmental Science
- Climatology
- Remote Sensing
Background:
- Coal mining drives significant land type changes, impacting local climate and ecosystems.
- Understanding these land use/cover changes (LUCCs) is crucial for regional development in mining areas.
Purpose of the Study:
- To simulate the impact of LUCCs on local temperature in Xilinhot city from 1980 to 2018.
- To analyze the regional distribution of surface energy and ground-air energy transfer processes affected by mining.
Main Methods:
- Utilized the Weather Research and Forecasting (WRF) model for climate simulation.
- Analyzed land use/cover changes (LUCCs) and their effects on surface energy fluxes (LH, SH, GRD).
Main Results:
- Mining activities had a minor impact on the overall regional temperature due to extensive grasslands.
- Specific mining areas experienced an average temperature increase of 0.822 K.
- Conversion to water bodies resulted in a cooling effect of 2.405 K, while urbanization led to higher temperatures due to increased sensible heat flux.
Conclusions:
- Land use changes, particularly urbanization and water body creation, significantly alter local surface energy balance and temperature.
- Targeted land management strategies are essential for mitigating negative climate impacts in coal mining regions.

01:16What is Climate?
19.2K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:50Global Climate Change
24.8K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:50Threats to Biodiversity
23.0K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

01:14The Carbon Cycle
40.2K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

01:26Influence of Earth's Curvature and Atmospheric Refraction on Leveling
301
During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.

01:57Adaptations that Reduce Water Loss
26.4K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
