Ask a Scientist!

The 2019 Climate Science on Tap – Ask a Scientist event will be an opportunity to ask experts in many different fields related to climate change and clean energy all those questions that may have been puzzling you or to join a discussion about impacts and solutions to climate change. There will also be representatives of many organizations and campaigns to answer questions about how you can get involved or be part of the solution.
