Glacier retreat

Ice cores
scientists often use ice cores to detect changes in temperatures. When snow falls it traps air into the ice. When scientists take a sample of ice it reveals the atmospheric gas concentrations at the time the snow fell. This is used to calculate temperature of each year.
Early spring and Rising sea levels are also the evidence of global warming.
