Have a question that's always confounded you about Earth's climate? Wonder why it matters that the climate is changing now if it has changed before? Or how scientists know changes seen in recent decades are the result of human activities, not natural causes?

Go ahead. Ask a climate scientist.

To submit a question, record a short, 10-15 second video with your question and upload it to YouTube -- and be sure to tag the video "#askclimate" so that we can find it. You can also simply post a question on Twitter with the same hashtag, "#askclimate."
NASA scientists will be recording video responses to some of the questions we receive. The responses will be posted to the NASAExplorer YouTube channel.
