On December 1 , 2011 , Hall gave an interview to '' National Journal '' in which he expressed disbelief in anthropogenic climate change . He accused climate scientists of concocting the evidence for anthropogenic climate change in order to receive federal research grants , citing the Climategate controversy and calling investigations which had largely exonerated them " straw-man reviews " . He stated that " I 'm really more fearful of freezing . And I do n't have any science to prove that . But we have a lot of science that tells us they 're not basing it on real scientific facts . " He responded to allegations that Republicans could be called anti-science in light of these views by saying " I 'm not anti-science , I 'm pro-science . But we ought to have some believable science ... . We have to be more careful what outlays we make for something that has n't been proved . " Hall introduced into the House the North Texas Invasive Species Barrier Act of 2014 ( H.R. 4032 ; 113th Congress ) , a bill that would exempt the North Texas Municipal Water District ( NTMWD ) from prosecution under the Lacey Act for transferring water containing invasive species from Oklahoma to Texas . The Lacey Act protects plants and wildlife by creating civil and criminal penalties for various violations , including transferring invasive species across state borders
