INTRODUCTION Glaciers serve as early indicators of climate change. Over the last 35 years, our research team has recovered ice-core records of climatic and environmental variations from the polar regions and from low-latitude high-elevation ice fields from 16 countries. The ongoing widespread melting of high-elevation glaciers and ice caps, particularly in low to middle latitudes, provides some of the strongest evidence to date that a large-scale, pervasive, and, in some cases, rapid change in Earth's climate system is underway. This paper highlights observations of 20th and 21st-century glacier shrinkage in the Andes, the Himalayas, and Mount Kilimanjaro. Ice cores retrieved from shrinking glaciers around the world confirm their continuous existence for periods ranging from hundreds of years to multiple millennia, suggesting that climatological conditions that dominate those regions today are different from those under which these ice fields originally accumulated and have been su

Introduction  Social media has deeply infiltrated everyone's life, including adolescence, and is thought by some to have a detrimental effect on individual people as well as society and local communities. However, while I believe that such either sites or applications are mainly beneficial to the adolescent, I agree that they have had a damaging effect on local communities. Positive Effect First, it can encourage creativity and innovative thinking. For teenagers like us, I think social media is an ideal and great place to share our work and get encouragement and feedback from others. Also, it can help us to come up with fresh and innovative ideas. In this way, social media can be a tool for creative teens. Second, it helps us develop social and communication skills. It gives teenagers the chance to interact with their peers and perhaps to make new friends safely too. Social media can help teenagers who might struggle to communicate offline to develop their social skills in a space
