Happy Earth Day! Time to don your recycled party hats and celebrate. Today more than 150 world leaders will meet at the United Nations Headquarters in New York to sign the Paris Agreement, a landmark commitment to reduce greenhouse gas emissions. For its part, the United States has pledged to reduce greenhouse gas emissions in 2025 by approximately 25% from 2005 levels. (The administration’s Clean Power Plan, currently mired in legal challenges, is a key part of the strategy to reach that goal.) Visit the UN’s website for more details about today’s ceremony, and grab some popcorn to watch the signing ceremony, which will be available via live webcast today. If the gathering in the Big Apple has you feeling a tad inadequate about your own efforts on behalf of the planet, do not despair. There is so much you can do, wherever you are. Visit earthday.org for a list of activities in your neck of the woods. We are particularly proud that our own hometown was named to LeafFilter’s Top 11 Cities to Celebrate Earth Day 2016, in large part due to the full slate of weekend activities at the Children’s Museum of the Upstate planned for the younger environmentalists among us.
