By initiating another glaciation.
Glaciers have only been around, this ice age, for about 3 million years.
Before that time there were other ice ages and warm periods between them.
Going further back there were periods of millions of years without glaciation.
Glaciation is only the norm during an ice age and not at other times. The world climate changes all the time.

What is a growing glacier different from a melting glacier?
A melting glacier gets smaller, but a growing glacier gets bigger.
What moraine is the maximum extent of a glacier is marked by a?
Terminal moraine is the type of moraine that marks the maximum extent of a glacier. This ridge of sediment is deposited at the furthest point reached by the glacier before it began to retreat.
What happen to the ice within the glacier when the glAcier stands still?
Stop fliwing
How do glaciers retreat?
Glaciers retreat due to a combination of increased melting at their lower ends and reduced snowfall at their upper ends. This melting is often caused by rising temperatures due to climate change. As glaciers lose more ice than they gain, they shrink and retreat.
Will plucking occur if a glacier is NOT advancing?
Plucking can still occur even if a glacier is not advancing. Plucking is more influenced by the presence of meltwater and the freezing and thawing of water in crevasses than the overall advance or retreat of the glacier.
Why might a glaclier advance or retreat?
A glacier may advance or retreat due to changes in climate, specifically variations in temperature and precipitation. When temperatures rise, melting increases, causing the glacier to retreat. Conversely, if temperatures drop or snowfall increases, the glacier can gain mass and advance. Additionally, factors such as changes in ice flow dynamics and geological conditions can also influence glacial movement.
What is a growing glacier different from a melting glacier?
A melting glacier gets smaller, but a growing glacier gets bigger.
What is a recessional moraine?
A recessional moraine is a glacial landform that forms when a glacier temporarily stops its retreat, depositing a ridge of unsorted till material. These moraines mark pauses in the glacier's overall retreat and are typically found behind the end moraine.
What states do not contain an active glacier?
The only state that does contain an active glacier is Alaska. Glacier National Park in Montana still has glaciers, but they are all in serious retreat. It is estimated that at the current rate, by 2030, they will be gone.

How can the geologist estimate how long ago the glacier was in the lower part of the valley?
A geologist can estimate how long ago a glacier was in the lower part of the valley by using methods such as radiocarbon dating of organic materials found in sediment layers or moraines left by the glacier. They may also analyze landforms and sediment deposition patterns to identify the glacier's extent and retreat. Additionally, studying the soil development and vegetation succession in the area can provide insights into the time elapsed since glacial retreat. Together, these methods help establish a timeline for the glacier's presence in the valley.
By how much did Peyto glacier change since the past century?
It is estimated that Peyto Glacier has lost approximately 70% of its volume over the last century due to climate change. This loss is evident in the retreat of the glacier's terminus and reduction in its surface area.
What will stop a glacier from moving downhill?
There needs to be matter greater in size and density to stop it/
True or false When a glacier is retreating the upstream ice is still moving forward toward the downstream terminus of the glacier?
A retreating glacier is one that is diminishing more in length that its upper supply regions can compete with. The snout of the glacier is retreating, but the main body of the glacier is still moving forwards. If this situation continues, the glacier will disappear.
