If you haven’t visited Grinnell Glacier in a while, be prepared for some dramatic differences. The changes in the glacier over the last few years may shock you. Take a picture! Even if you plan on returning next year, you may see a noticable change.
The rapid retreat of mountain glaciers is happening worldwide, a clear sign that our planet’s climate is warming. While Earth’s climate has undergone cooling and warming cycles in the past, the rate and magnitude of change we are witnessing today has not occurred since human civilization began. Scientific evidence suggests much of the current warming trend is being “pushed” by human activities. Of major concern is the build up of carbon dioxide and other greenhouse gases in the atmosphere.
Many human activities, especially those related to burning fossil fuels, release greenhouse gases into the atmosphere. Therefore, any actions or choices you make that can reduce these emissions will help slow this process.
