Understanding glacial geology is really important for predicting climate changes in the future. Here’s why:
Past Climate Clues: Glaciers hold clues about past climates. For example, ice cores taken from places like Greenland and Antarctica show that CO2 levels in the atmosphere changed a lot over the last 800,000 years.
Glacier Melting: Scientists have noticed that glaciers around the world are melting quickly. The National Snow and Ice Data Center says that Arctic sea ice has shrunk by about 13% every decade since 1980.
Rising Sea Levels: When glaciers melt, they add a lot of water to the oceans, which makes sea levels rise. The Intergovernmental Panel on Climate Change (IPCC) found that global sea levels went up about 3.3 mm each year from 1993 to 2010, mainly because glaciers were melting.
Effects on Ecosystems: The way glaciers melt changes rivers and affects plants and animals too. This shows how everything in the climate is connected.
By studying these signs, scientists can make better guesses about future climate changes and what they might mean for us.
