Scientists have discovered that South Africa's land is rising up to 2 millimeters per year, primarily due to drought-induced water loss, challenging previous mantle flow explanations. This finding, supported by GNSS and satellite data, highlights the impact of climate change on Earth's crust and offers a potential new method for monitoring water scarcity.,
A recent study reveals that parts of South Africa are experiencing land uplift due to drought-induced water loss, which reduces gravitational pressure on the Earth's crust, allowing it to rebound. This widespread vertical movement, tracked via GPS, highlights the significant impact of water depletion on geophysical processes and offers a potential new method for drought detection and climate monitoring.
A study reveals that South Africa's land has been rising by an average of 6 mm annually between 2012 and 2020 due to water loss from drought, with GPS data linking the uplift to seasonal and regional water depletion, suggesting the land's elevation changes are primarily driven by water storage variations rather than mantle activity.
A new study shows that South Africa's land has been rising by an average of 6 millimeters between 2012 and 2020 due to drought-induced water loss, with GPS data revealing a strong correlation between water depletion and land elevation changes, suggesting that water loss is the primary driver of this uplift.
Scientists have discovered that South Africa is gradually rising out of the ocean due to drought-induced water loss, which reduces underground pressure and causes the land to uplift, offering a new method for monitoring groundwater reserves and managing water crises.
Greenland, a major source of meltwater contributing to rising sea levels, is experiencing faster land uplift due to the melting of its glaciers, leading to the emergence of new landmasses. Data from GPS stations reveals that Greenland's bedrock has risen up to 20 centimeters in the last decade, with the loss of mass from peripheral glaciers contributing significantly to this uplift. This phenomenon, driven by climate change, has implications for sea level rise estimates and highlights the rapid local changes occurring in Greenland.
As Greenland's ice sheets melt, the landmass is gradually rising due to glacial isostatic rebound, with up to one third of the uplift in some areas attributed to glaciers receding. Data from GPS monitors embedded into Greenland's bedrock revealed that significant land uplift is occurring closest to the largest glaciers, with the Kangerlussuaq Glacier in southeast Greenland experiencing the fastest rise. Studies also indicate that Greenland's glaciers are melting faster than previously estimated, with 20% more ice melting along the edges than previously thought, contributing to sea level rise.
Research by the Technical University of Denmark reveals that Greenland's bedrock is rising at an accelerated pace due to the melting of its ice sheet, with an uplift of up to 20 cm over the last decade. This phenomenon, observed through the GNET network, challenges the global trend of rising sea levels and highlights the localized impacts of climate change. The study emphasizes the need for advanced monitoring technologies to understand the complex dynamics of environmental changes and serves as a reminder of the urgent need for continued observation and study of our changing planet.
