The overall trend of increasing temperatures can be seen from multiple agencies from different parts of the world
NASA has kept record of annual average temperature since 1880 and found that 2022 was the fifth-hottest year on record
The Goddard Institute for Space Studies (GISS) records Earth’s surface temperature (GISTEMP)
Their work is verified through comparing data with organizations such as the National Oceanic and Atmospheric Association (NOAA)
NASA also checks work with their own satellites orbiting the Earth and obtaining atmospheric readings
All of the evidence that NASA and other organizations have collected asserts that Earth’s climate is warming
The red/orange/yellow areas indicate overall warming, though some areas have cooled
Land areas warmed more than the ocean
Polar regions saw the most significant increase in temperatures
Glacier: a permanent body of ice that forms where climates are cool enough to maintain snow all year long
Glaciers form when fresh snow lands on a ground surface; due to the cold temperatures, it does not fully melt over the course of a year. The next year another layer of snow will be deposited on top.
Over time the snowflakes lose their edges and the snow becomes more tightly packed.
With further burial, the snow transforms into a packed granular material called firn
As layers of snow accumulate, the weight compresses the lower layers into glacial ice.
Rising global temperatures increase the melting rate of glacial ice
