According to Environment and Climate Change Canada "warming over the 20th century is indisputable and largely due to human activities" [27] adding "Canada's rate of warming is about twice the global rate: a 2° C increase globally means a 3 to 4 °C increase for Canada". [28] ECCC lists impacts of climate change consistent with global changes.
Most avalanches occur spontaneously during storms under increased load due to snowfall and/or erosion. Metamorphic changes in the snowpack, such as melting due to solar radiation, is the second-largest cause of natural avalanches. Other natural causes include rain, earthquakes, rockfall, and icefall.
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes. [28]
As well as the addition of melted ice water from glaciers and ice sheets, recent sea level changes are affected by the thermal expansion of sea water due to global warming, [28] sea level change due to deglaciation of the last glacial maximum (postglacial sea level change), deformation of the land and ocean floor and other factors. Thus, to ...

Canada's annual average temperature over land warmed by 1.7 °C (3.1 °F) between 1948 and 2016. The rate of warming is highest in Canada's north, the Prairies, and northern British Columbia. The country's precipitation has increased in recent years and wildfires expanded from seasonal events to year-round threats.

What Causes Avalanches? The behavior of an avalanche depends on the structure of the snowpack, but that's only one ingredient. An avalanche requires all the wrong conditions at the wrong time.
