Our Changing Planet: A Tu Bishevat Presentation

With Spiro Alexandratos, PhD

Our Changing Planet: A Tu Bishevat Presentation picture

Did you know that many of the world’s 60,000 species of trees are under threat because of global warming and other environmental stress? As we observe Tu Bishevat (the New Year of the Trees) this year, we will find out why.

Planet Earth is undergoing changes at an unprecedented rate. What used to take millennia now takes 100 years. In 2019 alone Anchorage shattered an all-time record at 90 degrees, and France hit a temperature of 114.6 degrees.

But there has always been extreme weather. What’s different now? And it is not just weather: even the oceans are changing as their acidity increases. Could there be a causal link between the simple CO2 molecule and the changes we see in the weather and oceans? And if there is, how could so many people (1-in-3) deny it?

Come to hear Dr. Spiro Alexandratos explain the science behind these changes to Planet Earth – and the psychology of denial. And come for our traditional Tu Bish’vat supper, with all the fruits and treats we enjoy each year.

Dr. Spiro Alexandratos is a professor of chemistry at Hunter College and in the Ph.D. program at the Graduate Center of the City University of New York. He received his doctorate at the University of California at Berkeley. He is a Fellow of the American Chemical Society and a Fulbright Scholar with an ongoing program in France.
