A glacier is never going to form in Sacramento, regardless of it being 70 degrees in May

It's May, the school year is almost over, and it's time for three months of relaxing by the beach and doing outdoors-y type things like hiking and camping. However, for these types of things, a warm temperature is somewhat necessary. Unfortunately, the temperatures lately have been somewhat on the cooler side. Although chilly and not as warm and humid as it usually is this time of year, it is not quite cold enough for say, a glacier to form. A glacier is a large formation of ice resting on land or floating in a body of water. In order for a glacier to form, the climate obviously must be much cooler than it is in Sacramento in May, regardless of how chilly it currently is. Glaciers form in one of two places: either they form in areas of high altitude, such as mountains, or they form outside of the mountains. When formed on mountains or other areas of high altitude, the glacier is called "Alpine". When formed outside of the mountains, in areas of high latitude, the glacier is called "Continental". Wherever the glacier is formed, it must be in an incredibly cold area with high levels of snowfall. This is because glaciers are merely the accumulation of snow that is packed down and compressed and turns into ice. The weight of the top layers of snow compresses the bottom layers of snow, turning it into firn, a pebbly type of snow between soft, fluffy snow and hard, solid ice. After the firn stage, the snow turns into solid ice and becomes a glacier. This can take an extremely long time; as long as 1,000 years in a dry climate such as Antarctica. Obviously, this is never going to happen in Sacramento. 70 degrees in May or not. However, global climate change makes anything possible.
