bill nye to climate change deniers: you cant ignore facts forever

bill nye the science guy explains that climate change deniers and other anti-scientists are entitled to their opinion but that doesn039t mean they get a seat at the table with the grown-ups bill is the ceo of the planetary society http:planetaryorg don039t miss new big think videos subscribe by clicking here: http:googlcptsv5for more bill nye the science guy go to http:billnyecomtranscript -david gregory: youve heard the president in drought-stricken california saying that these weather emergencies in effect are creating the conditions that the government has to actmarsha blackburn: david i think that what it brings to mind is how we utilize the information that we have and we all know and i think that bill would probably agree with this neither he nor i are a climate scientist he is an engineer and an actor i am a member of congress and what we have to do is look at the information that we get from climate scientists as you saidbill nye: so she did something which is very common in the climate denier community or whatever you would call it is to talk about credentials so marsha blackburn representative in the us congress from tennessee said well i am a congresswoman and bill you039re just a mechanical engineer so you039re not really a climate scientist and what i would say is what we039re talking about in this level of climate science is you don039t need to be a full-time climate scientists to understand it furthermore as far as my credentials everybody i039m a mechanical engineer i took a lot of physics all i did was take physics physics physics physics and when you039re done with formal physics then you take mechanical engineering which is just applied physics i get it i can understand what039s going on we039re putting carbon dioxide in the air at a prodigious rate and the world is getting warmer and you can know this by looking at the neutrons in the ice you can know this by looking at the pollen grains per cubic centimeter in the sediment of ponds you can know this by looking carefully at the rings on trees during warm seasons wet seasons cold seasons dry seasons and you can work your way back and figure out that the earth is getting warmer faster than has ever gotten before and that039s the problem it039s not that the world hasn039t had more carbon dioxide it039s not the world hasn039t been warmer the problem is the speed at which things are changing we are inducing a sixth mass extinction event kind of by accident and we don039t want to be the extinctee if i may coin this noun so i mean as far as miss blackburn sounded like she had been coached on denial bullet points or talking points and i very much enjoy taking those people on but meanwhile it breaks my heart because we got work to do and the fossil fuel industry has really gotten in their ears and it039s really troublesome we039re the world039s most technically advanced country or if the us isn039t the most technically advanced it039s certainly in the top ten i mean you could say japan new zealand are very sophisticated societies but the us is where iphone039s are invented what have you the internet it039s still a significant place and so to have a generation of science students being brought up without awareness of climate change is just a formula for disaster i mean this is everybody kinda knows thisso i think as an observer and i may be wrong as i like to say you may be right as an observer it looks like the us039s strength is its weakness so people came here from all over the world for freedom to think and act the way they wanted especially freedom of religion so we ended up with both the people who framed the constitution which is a fabulous thing and people who asserted that the garden of eden was in missouri and there039s no police for that sort of thing you039re allowed to believe whatever you want it039s great but with that was this for them and i emphasize them the other side consequence of that was you could also ignore facts of science for a while and now its coming to a head but man it039s really divisive isn039t it it039s really something that living things change from generation to generation through a process that darwin and wallace alfred wallace called natural selection or descent with modification those are true things those are facts tectonic plates move and that039s a fact and the world is getting warmer because of human activity that039s a fact if you had somebody who really strongly believed the earth was flat you wouldn039t have to have that person on a television show with the people who believe the earth is round transcript truncateddirected produced by jonathan fowler dillon fitton and elizabeth rodd
