we are concerned a handful of media conglomerate control what we see here a. sunday at 9 p.m. national review executive editor discusses his book melting pot or civil war of the son of immigrants makes the case against open borders. ..

. >> it is every four years congressionally mandated since the early nineties it is a sweeping survey of the latest in climate science it is very comprehensive of all sectors of the society as a broad-based survey of where we are now and what we know about climate change. >> how much of the scientist or specificcist people were done or was it started earlier quick.

>> for the last two years i think the actual writing to place under the trump administration the lead author pointed that out yesterday starting in 2017 from texas tech but this is career staff largely from 13 different federal agencies some of the best scientist in the world in this area they have more than 300 actually contributing to this report it is broad-based in terms of the input all across the administration. >> host: so what was the and with the climate situation here in the us the information here is nothing new necessarily in terms of what we have known for years that builds upon that and takes a littler further to show us and emphasizing in this report that climate changeat is here

right now it just will not happen in the future it is already happening being here so in miami with nuisance flooding on a sunny day where parts of the city are flooded even without any sort of storm there is climate gentrification slightly higher above sea level are worth far more's there are pockets throughout the united states you can see examples right in front of you obviously the wildfires in california. >> host: one of the connections the report makes of climate change to the economy what are those connections? it cost to the billions of dollars every year to have a

heat wave of a premature death that will cost tens of billions of dollars per year a huge hit to infrastructure. those that will experience more extreme stores - - storms inland we will see more and more of that of the future according to this report. >> host: joining us from the report scott waldman is here. you said it was largely written by members of the trump administration. >> by career staff of the federal government. this is consistent everything he has said that he rejects

the science that he does not believe this report he has said things like that inla the past that it's cold on thanksgiving where is global warming and said things like that whether atmospheric conditions over a short period of time or climate conditions over a longer period of time. so one single cold day in late fall does not equal the absence of climate change. >> host: the science that is dead de on - - done is that all brand-new research or does it depend on old research to skew the results quick. >> there is certainly plenty of new research one of the new intriguing areas that is different from previous versions is looking at how we can attribute climate change

to a phenomenon like individual hurricanes to look at hurricane irma that has caused devastation fingerprints but also with heat waves and a growing - - also a growing body of science how climate change contributes to any individual heat wave. >> host: give me an example to that human connection. >> one of the first heat waves they studied in europe in the early 2000's i don't remember 38 number off my head but or 40 percent they could say was directly related to human activity.

>> host: also actions to reduce risk what are those recommendations as far as what now quick.o right >> we have known for some time we have to reduce greenhouse gas emissions and carbon dioxide the primary way we pollute the earthwa especially here in the united states the direct transportation sector and power plants to make electricity those of the primary sources of pollution andd we have to cut that drastically also modeling in the past has been fairly accurate with those temperature increases are at the higher end of the modeling. >> so the integration of climate and the implementation of activitiess increase since the national assessment

development of energy - - standards can you expand quick. >> that insurance industry and banks are a factor due to whatever economic equation they are making to recognize to ensure a bunch of homes in southern florida to account for climate change how that affects us in five or ten or 50 years and with the mplculation these are profound economic hits. it is also international companies like thailand is experiencing the flooding and

that is an example. >> host: scott waldman is joining us. the calls are lined up first is los angeles republicanom line good morning. >> you're talking about the wifires in california. that wasn't started by climate change that was started by the electrical companies. they started that. it would've been as it was if nobody sparked the fire. but but with all types of machinery. and so down in guatemala or mexico and with any co2

activity. and then start to run refrigerators. . >> if you look at wildfires and with that climate change but it did have a number of conditions related to climate change that fueled that that made it worse. the beetle kill from the trees directly were a result of the beatles moving northward to decimate more for us. then the hotter condition dries out the ground and fuels the fire. so when the president went there and stood in smoldering ruins he was standing on the front lines of climate change that is exactly what this report says.

it with that devastating to spark those wildfires it is that condition to get dramatically worse. . >> what about indigenous peoples in the arctic and alaska and for millennia have been harvesting bowhead whales but now they cannot get to the edge of the ice where the whales swim to harvest and they been doing this for more than a thousand years that is one example and then to be a dramatic issue.

>>caller: the jet stream is experimental but then like jesse event or a 2014. >> the government is not trying to manipulate the weather. they are making. they are making. >> host: democratic line go ahead. >>caller: i had a discussion with my friends.

>> but it does significantly essentially flatulence from cows is one example. we eat a lot of red meat and that adds to greenhouse gases and methane is particularly powerful eight times more powerful than carbon dioxide. so yes it does and to make land for cattle pasture we are cutting down forest and the trees that absorb co2. >> host: if you were to find this report online we have a link as a series of maps and charts to look at the findings of the report. but sarah sanders that there is plenty of report over time

at the unprecedented rate with that amount of atmospheric carbon dioxide we are still grappling of modern civilization. >> host: also looking at how clan - - climate change is a standout on the united states map. >> that's a great question what makes this report t unique and why it's worth spending time with it that this can show you exactly how it will affect your region you can see how it will affect your backyard if you live in the southeast you should expect to see rising sea levels in the northeast, increased extreme

storms in the summer to cause in land flooding or devastation for farmers. you can pick and in the midwest cuts in agricultural yields these are things he can better plan for and adapt to if we look at the science in a realistic way. >> host: flooding in louisiana from extreme rainfall, the action of the planning commission this is just one of the pieces of information the next call is from louisiana. the independent line go ahead. >>caller:. >>. >> for over ten years i have been photographing chem trails in my backyard that you said

the government is not manipulating the weather is a joke. climate engineering, geo- engineering, do some research that would be thech headline news that is better were further what they are doing to manipulate the weather. i have been watching chem trails for over ten years. >> host: you may have to expand on that. >> chem trails are not actually happening. i don't know where you get your resources from like nasa or know of some of the best scientific agencies in the world this is a great example of the product they produce with plenty of data echoing agencies from around the world. >> host: republicans from illinois go ahead. >>caller: i have a couple questions i would like you to answer them for y me.

in the united states with climate change is that not very accurate anyone you should be using in russia is more accurate? and if not for the millions of trees in california that should have been thinned out why did california just passed two bills that they will start cleaning that out? that is my question. >> our science is the best in the world we measure the effects of climate change through our satellite system and based on nasa and data that comes in through noah - - t16 this report makes it clear we have high confidence and

low confidence so if you look at the internet you can basically find any claim about climate that you would like certainly there is a whole range of climate from certain pieces of data that cherry world tom around the make claims that are wild or untrue but that there is plentyrn of information with the trump administration and they are not seeing any alternative bodies to negate any of those findings. >> host: high confidence or low confidence give examples. >> it depends on the missions that come out. or by 2100. so they are looking at hurricanes and that there is evidence that hurricanes will worsen over time and that is

increased with the precipitation out of the air it is the number of hurricanes to increase over that time the worse hurricanes but not necessarily more. >> with the overall warming what are we looking at quick. >> it depends on what we admit and with one.5 degrees celsius. so if you just go outside a couple of degrees fahrenheit does not make a difference but

that atmosphere over time can mean entire cities in the us that are largely underwater miami will have a very difficult future existing as it currently does moving in that type of world. that is that timescale and with those severe effects in the united states and that is what is showing us and it is fairly clear where this picture continues to emerge but it is getting worse. we are not even disputing what we will do about it. where climate policy is the political conversation but the actual science itself is increasingly clear. it is a relatively small handful of researchers of washington-based think tanks

largely funded by the fossil fuel agency and then all the other side all these other agency saying this is a serious problem come is getting worse, caused by us and increasing at a rapid rate. >> host: what are the other countries of the world doing to mitigate or reverse this problem question because the president's other - - critical of other countries that they are not doing enough to meet their targets. china is going heavily into coal to drive up emissions and then and then that's what takes to cut greenhouse gas emissions.

>> and with what they try to impose it as it riots but then protest in the street. >> people are pretty angry there is a way to put in a carbon tax a lot of that climate science it isn't anything to believe or disbelieve but simply science but those that accept that reality and to put forward a very aggressive plan with those omissions of the carbon tax that was introduced the other day and also to put a price on carbonsi emissions and then give refunds back to individual families to take that off your electric bill

but there is a number of approaches we could take it and increasingly for republicans to move on this issue. >> host: e-and e-joining us. . >> and he said what humans are it is that persistence in houston with all of that flooding. a lot of homes in the swamps in california they are using up the water. but then people are building homes that water is not out there and then all the cars and gasoline catch on fire then increases the fire i remember california when the smog hit. if you change it and make it

more simple that the human is causing the climate. >> that is a great .1 way to think about climate change is a threat multiplier and the military is prepared preparing for climate change but those are great points for both of those. and if it is flood prone where didn't have housing before that causes that level of devastation more than 80 people tragically died but that was a three prong stool making conditions worse making fires worse and then that

development that makes people more vulnerable but forest management and it is nearly impossible to clear these areas by what they are suggesting s but della permit could be controlled to mitigate the effect on climate change. >> and the military quick. >> also some of the worst flooding in the united states because of where it sits along the coastline so the military for years is fighting sea level and climate change and adjusting the height of the docs to keep the nuclear fleet and installation their safe. they are not debating if it is real they are just preparing

for it outside of the washington infighting. >> host: independent line hello. >>caller: thank you for taking my call. and for those reasons. >> that is a great question john mccain and other republicans were on board to see policy that would help mitigate climate change and a number of political groups and washington-based think tanks from the heartland institute that have been tremendously successful there's no reason

you can come up with climate policy with democrats and republicans alike. just like tobacco companies funded all kinds of research tamped down that harmful nature of smoking cigarettes the energy companies did the same thing with cole and even exxon has backed away but that has created a ripple effect that we see today playing r out unfortunately other countries conservatives are completely on board with policy and you have a number of politicians and then to move aggressively on climate change but it is literally rejecting thisit report that is science base with no other science to dispute what it says.

>> you also talk about social media quick. >> "the daily caller" has been niprimary funder by the coke brothers from these primary denial they pick up on those uncertainties it is a greater amount of certainty so the president picks up on those talking points and that ample fates - - amplifies that affect. >> republican line new york. >>caller: just a quick comment than a question i am just finishing reading about hurricanes but at one point they talk about the hurricane that swept through the caribbean in 1780 was two storms it really destroyed a

lot of the ships that ultimately were not able to participatebr in defending britain or the french to get up to the yorktown area. they were massive they estimated 20000 people died indefinitely category four or five hurricane hurricanes. these have been around so one of my problems with the way climate change advocates discuss climate change there is a difference they try to compare the two. but the other question i have is there any ideal temperature? . >> nobody says bad hurricanes have not happened in the past

it is just saying the conditions that will create more extreme hurricanes are caused by climate change that is warmer ocean currents that does make hurricanes worse. and then we will not see more but more devastating hurricanes increasingly likely. >> one more call from gary in kentucky. >>caller: the thing that i have every part of america has been hit by some type of

disaster. itit isn't about global warming but it is trying to wake people up. >> just one report about what is the ideal temperature that is a great question i have talked about that and it is what we have right now you don't want to increase anymore. >> host: with a trump administration basically d denying this report doesn't get filed and not your - - and not used quick. >> in the next two years for those that will pick up on this as they file any lawsuits that they deem necessary to back that deregulatory efforts to roll back greenhouse gas emissions by the trump

administration. but one way is to use this around the country and with those safer conditions if that climate change and effect with that infrastructure. and with that unpleasantness in thent future. and that that local government to have that ability. . >> we do cover energy policy broad-based looking at climate change and with those pipelines and we have reporters all over the country. >> host:
