Have a question that's always confounded you about Earth's climate?
Published on Sep 4, 2013
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.
Is the dust storm that swept through Sydney a sign of climate change? Visit Science
Is the dust storm that swept through Sydney a sign of climate change? Visit Science Magazines YouTube Channel for interesting vidoes of our universe. Australia is in a 10 year drought with California in its third year, could dust storms happen in California?
Is there any merit to the studies that show that historical CO2 levels lag behind temperature, and not lead them?
Yes,
Is there any merit to the studies that show that historical CO2 levels lag behind temperature, and not lead them?
Yes, there's merit to those studies, says Peter Hildebrand, Director of the Earth Science Division at NASA's Goddard Space Flight Center, responding to a question from Twitter (https://twitter.com/Seth_b_clark/stat...).
In the pre-industrial age, the CO2 response to temperature was that the temperature would go up and CO2 would go up. Or if the temperature went down, CO2 would go down. Because when the temperature rose, the whole biosphere revved up and emitted CO2. So we understand that process.
In the post-industrial age, the opposite is true. Increasing CO2 in the atmosphere is leading to increased temperature. So two different things happened, one pre-industrial, where temperature was driving the CO2, and post-industrial, where CO2 was driving temperature. Which means a completely different physical-biological process is going on.Published on Sep 24, 2013
