Why Are Sea Levels Rising? GOP Lawmaker Says It's Because of Falling RocksDuring a Thursday meeting that was supposed to be about using technology to address climate change, lawmakers*on the House's Science, Space and Technology Committee sparred over the cause of rising sea levels. Some conservatives at the meeting shared their*denial*that climate change is, in fact, a real*phenomenon. “Every time you have that soil or rock deposited into the seas, that causes the sea level to rise, because now you’ve got less space in those oceans, because the bottom is moving up," Brooks said, speaking over*Philip Duffy,*a climate scientist who previously served on the White House National Science and Technology Council.
