Hi, I am Aaditya Saha. I am a 2nd term TUNZA ambassador for the United States of America. I am from Atlanta, Georgia, and I am in 9th grade. I want to make a positive impact on the environment, and that is what motivates me to be an ambassador and to perform the actions that I do. I encourage everyone, especially the new members, to read what I have written about my past actions (just like I have been and will continue to do).

Climate change is well documented to be happening right now and is having detrimental effects on humans and the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.

Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Antarctica is melting, and cold seasons there are getting shorter and shorter. Scientists have high confidence that global temperatures will rise 2.5-10 degrees in the decades to come, largely due to greenhouse gases produced by human activities. In the US, many regions have been experiencing higher levels of precipitation, but many other places in the world are dominated by droughts and heat waves. Hurricanes, cyclones, and typhoons have been getting stronger and stronger. Finally, thousands of thousands of species are going extinct or are endangered.

We need to do everything that we physically can in order to combat climate change, whether through recycling, stopping the production and use of plastics, passing regulations on air pollution and factories, or even by doing small things like carpooling to work or school every day or walking and using a bicycle.
