Ask A Scientist: get answers to your environmental questions

Follow Environment and Climate Change Canada on Facebook and Twitter to see the featured topics of the month, meet our scientists and submit your questions. You will have the opportunity to have your question answered by one of our world-class scientists and you could be featured in one of our #AskAScientist episodes!

How to submit your question

First, follow us on social media to learn about our featured topics.

Then, film yourself asking your questions on the featured topic, in English or French, or both. Send it to us on social media via private message on our platforms or tag us with #AskAScientist. Make sure to use our handle on Facebook (@EnvironmentandClimateChange) and on Twitter (@environmentca), and ensure your post is set to “public”.

If your question is selected for an episode, we will contact you through private message on social media to let you know the next steps, including signing a release form and obtaining the original video clip of the question.

Filming tips

• Film in 1080 high definition (HD) or 4k (Ultra HD)

• Speak clearly
• Use the rear camera and look at the camera lens
• Stand 6 to 12 feet in front of a simple, tidy background
• Do not stand in front of bright light sources such as windows
• Position the camera or phone just below eye height
• Keep the camera or phone stable by using a tripod or similar
