Global Climate Change01:50

Global Climate Change

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.
What is Climate?01:16

What is Climate?

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.
Elevation of Intermediate Points on Vertical Curves01:20

Elevation of Intermediate Points on Vertical Curves

Vertical curves are essential in roadway design because they provide smooth transitions between varying roadway grades. Designing vertical curves involves calculating intermediate elevations and identifying the curve's highest or lowest point, which is essential for optimal roadway performance.Intermediate elevations on a vertical curve are determined using the tangent offset method. This method considers the initial elevation at the start of the curve, the grades, and the curve's geometry. The...
Precipitation Processes01:12

Precipitation Processes

The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...
Influence of Earth's Curvature and Atmospheric Refraction on Leveling01:26

Influence of Earth's Curvature and Atmospheric Refraction on Leveling

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. Over a...
Precipitation Gravimetry01:03

Precipitation Gravimetry

Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

Summary

Climate change is increasing landslide volumes in high mountain regions. Warming temperatures cause more rain and less snow, leading to upslope migration of landslides in the Himalayas.

Area of Science:

  • Earth Science
  • Climate Science
  • Geology

Background:

  • High mountain regions, especially cryospheric landscapes, are sensitive to climate change.
  • Recent trends in precipitation and temperature are altering hillslope stability.
  • Understanding these changes is crucial for hazard assessment in areas like the eastern Himalayas.

Purpose of the Study:

  • To investigate the impact of climate change on landsliding in high mountain regions.
  • To quantify changes in landslide activity in the eastern Himalayan syntaxis.
  • To assess the role of warming temperatures and changing precipitation patterns.

Main Methods:

  • Compilation of a comprehensive landslide inventory (8607 events, 1987-2020).
  • Analysis of climate-related landslide distribution and volumes at high elevations (>3000 m).
  • Correlation of landslide trends with precipitation and temperature data.

Main Results:

  • A five-fold increase in annual landslide volumes at high elevations over the past three decades.
  • Upslope migration of landslide distribution linked to retreating glaciers and melting permafrost.
  • Extreme denudation rate of 1.0 ± 0.3 mm yr⁻¹ driven by climate-related landsliding.

Conclusions:

  • Climate change is significantly escalating landsliding in high mountain areas.
  • Warming-induced shifts in precipitation (rain vs. snow) are a key driver.
  • Increased landslide activity amplifies sediment cascades and risks of cascading hazards in High Mountain Asia.
