Today is the day

Happy Earth Day!

›Since the first Earth Day in 1970, when 20 million Americans celebrated it, the day has gone global.  In 1990, 200 million people in 141 countries took part. ›In 2000, more than 4500 organizations in 180 countries marked the 30th Earth Day in their own ways.

Here's how I spent Earth Day last year.

Here’s how I spent Earth Day in Qatar last year.

Last year, 1 billion people across the globe feted the 45th Earth Day.

Today, to mark Earth Day 2016, almost 170 countries (up from my Monday post) are sending heads of state and other high-ranking government officials to represent them at UN HQ in New York City to sign the Paris Agreement.  Secretary of State John Kerry will sign for the United States. You may watch the signing ceremony here starting at 9:30am.
