Need to Know: Science and Insight looks at the issues we all Need-to-Know at this time of pandemic, and existential crisis of climate change and unravelling of nature’s life supports.

In each issue I try to address a least one current Need-to-Know issue and explain why it’s important for all of us to know and what can be done about it. I’ll also find information you can use right away along with a bit of universal wisdom to consider…. And sometimes there will be things that may bring a smile or two.

About Stephen 

I’m writing Need to Know to share the insights and understanding I’ve gleaned from the many smart and wise people from all over the world I’ve interviewed in my 25 years as an award-winning science and environmental journalist writing for National Geographic, The Guardian, Vice and dozens of other publications.

One of the reasons I left my corporate career all those ago was to write about what I believed were need to know science and environmental issues. 

My work has appeared in dozens of publications including National Geographic news, The Guardian, Vice, New Scientist, Al Jazeera, Maclean’s Magazine, Changing America, The Toronto Star, Wired News, and publications in Europe and Asia. I received the SEAL Award for Environmental Journalism two years running for my work documenting climate change impacts and solutions at National Geographic and Vice

I previously received the Prince Albert/United Nations Global Prize for reporting on international environmental issues as a result of my years as the senior science and environment correspondent at the Rome-based, Inter Press Service News Agency (IPS), the world’s largest not-for-profit news agency.

My one and only book, “Your Water Footprint   (“…a brilliant and shocking exposé on precisely how much water we use…”— Publishers Weekly) was awarded Best Science Book of the Year in Canada.
