Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
There are scientists who reject that uplift is the sole cause of climate change and are in favor of uplift as a result of climate change. Some geologists theorize that a cooler and stormier climate (such as glaciations and increased precipitation) can give a landscape a younger appearance such as incision of high terrains and increased erosion rates.

Subsidence is the compaction of soil resulting in a lower elevation. Subsidence can occur when oil, gas, or groundwater are extracted. These substances hold the land up until they are removed. Compaction due to heavy urban infrastructure also occurs. [10] Sea level rise due to climate change is another threat to coastal land. [11]
Thermal erosion is the result of melting and weakening permafrost due to moving water. [24] It can occur both along rivers and at the coast. Rapid river channel migration observed in the Lena River of Siberia is due to thermal erosion, as these portions of the banks are composed of permafrost-cemented non-cohesive materials. [25]
The Arctic Ocean's ability to absorb carbon dioxide from the atmosphere appears to be waning due to melting permafrost and worsening coastal erosion.
Water scarcity is an increasing problem due to many foreseen issues in the future including population growth, increased urbanization, higher standards of living, and climate change. [ 24 ] Industrial and domestic sewage, pesticides, fertilizers, plankton blooms, silt, oils, chemical residues, radioactive material, and other pollutants are some ...
Although the terms erosion and denudation are used interchangeably, erosion is the transport of soil and rocks from one location to another, [1] and denudation is the sum of processes, including erosion, that result in the lowering of Earth's surface. [2]
Degraded land also releases greenhouse gases, making climate change worse. Further possible impacts include: A temporary or permanent decline in the productive capacity of the land. This can be seen through a loss of biomass, a loss of actual productivity or in potential productivity, or a loss or change in vegetative cover and soil nutrients.
