http://www.sciencemag.org/news/2018/05/ ... level-riseRep. Bill Posey (R-FL) said scientists said in the 1970s that the Earth was cooling, a popular talking point of climate skeptics and the subject of a fake Time magazine cover that has become a meme. Duffy corrected him and said that was essentially an outlier position at the time and that scientists long ago determined that humans were warming the planet.
Posey also asked how carbon dioxide could be captured in permafrost in the periods before humans existed. Duffy told him that it was from non-decayed organic matter. Human activity is now causing the Arctic to warm and thaw the ground, releasing the carbon into the atmosphere, Duffy said.
Posey then asked about theories related to warming being beneficial for habitats and to people.
"What do you say to people who theorize that the Earth as it continues to warm is returning to its normal temperature?" Posey asked.
"Look, if you want to characterize a temperature above today's temperature as normal, you're free to do that, but that doesn't mean that's a planet we want to live on," Duffy said.
"I don't want to get philosophical; I'm trying to stay on science here," Posey said.
"I'm not getting philosophical; I'm getting extremely practical," Duffy said. "I'm being extremely practical — if we let the planet warm 2 or 3 degrees, we will have tens of meters of sea-level rise, and the community where I live will essentially cease to exist."

Re: Beating Guam Guy At His Own Game
God - those "lawmakers" come to some dumb conclusions. Rep. Mo Brooks says NASA, in his state, tells him something else. There isn't any climate research conducted there. It's a research center and support for Kennedy Space Center. He takes the "word" of jet propulsion experts over scientists with NOAA? What a moron.

Re: Beating Guam Guy At His Own Game
Republicans do make themselves look bad in sessions like this. They need to get a statistician to run for office ang get elected, put him on one of these committees, and make him the guy that talks to the scientists whether it's climate change or any other issue. A statistician would be good because statistics is basically the backbone of all inferential science. A statistician can address issues of cause and effect inference in just about any field.
Having said that the comment about tens of meters of sea level rise might be a bit much. If you look at the NASA sea level projection portal at https://sealevel.nasa.gov/understanding ... rojections you'll see this:
This is an example, I think, of media bias. It's pretty easy to critically evaluate what the guy giving the testimony was saying and raise questions about that statement on sea level rise. But I don't think most media people are interested in that. I think they just accept what people like that say. Meanwhile if somebody on the other side says something they critically evaluate it to the nth degree. I don't think it's a conscious thing. But I think it happens all the time.
Having said that the comment about tens of meters of sea level rise might be a bit much. If you look at the NASA sea level projection portal at https://sealevel.nasa.gov/understanding ... rojections you'll see this:
What's the projected temperature change associated with that? The EPA page at https://19january2017snapshot.epa.gov/c ... emperature has this statement:Projections of global sea level rise by 2100, the year upon which climate modelers typically focus, vary widely depending on modeling methods and on assumptions—the rate of increase in greenhouse gas emissions, for example, and especially how ice sheets will respond to warming air and ocean water. Recent projections range from 0.2 meters to 2.0 meters (0.66 to 6.6 feet)
So saying that an increase in 2 or 3 degrees global temperature would mean a tens of meters rise in sea level does appear to be an exaggeration with respect to what's expected. Also note that there is a lot of uncertainty in the projections. If you read around those two web pages I linked a little bit you can see that.Increases in average global temperatures are expected to be within the range of 0.5°F to 8.6°F by 2100, with a likely increase of at least 2.7°F for all scenarios except the one representing the most aggressive mitigation of greenhouse gas emissions.[
This is an example, I think, of media bias. It's pretty easy to critically evaluate what the guy giving the testimony was saying and raise questions about that statement on sea level rise.

Re: Beating Guam Guy At His Own Game
I don't know if "normal" applies but we are indeed well below what the average of believed temperatures over the time since large vertebrates started to thrive on land. Here is a graphic:"What do you say to people who theorize that the Earth as it continues to warm is returning to its normal temperature?" Posey asked.
"Look, if you want to characterize a temperature above today's temperature as normal, you're free to do that, but that doesn't mean that's a planet we want to live on," Duffy said.
One could disagree about what's meant by the time during which large vertebrates have lived on land but I would say for sure that was happening during the Permian period and arguably during the Carboniferous period. So you're talking about about 360 to 290 million years ago. And you can see that the global temperature now is believed to be lower than it's been during most of the time since then. And it'll be lower than it's been most of the time since then even if global temperatures rise by the upper limits of the uncertainty intervals associated with current projections by the climate science community.
So what the politician was saying was basically referring to an accurate point.

You want to hit liberals on the issue of CO2 emissions and energy, you should focus on their favoring of feel-good policies like:
1. The Paris Climate Deal
2. Vehicle Emission standards
3. Cap and Trade proposals
4. Renewable energy
All of those things amount to slowing down the bleeding of a severed artery. The renewable energy issue is an especially good one to hit because the more places like Germany and California get involved with renewables the more it becomes apparent that it's going to be much more expensive and difficult and slow to reach 100% renewable energy than a lot of greenies think.
There are other reasons to eliminate fossil fuels besides climate change, and "the science could be wrong" isn't going to cut it.

Re: Beating Guam Guy At His Own Game
My bet would be that our species would never have evolved if temperatures hadn't cooled. Here is a chart showing global temperature estimates during the Age of Mammals (Cenozoic Era) from an on line textbook at https://opentextbc.ca/geology/chapter/1 ... s-history/:kalm wrote:How many humans were walking around during the carboniferous?
I think that even slight changes in the history of the climate would have meant completely different evolutionary outcomes. Our Family, Hominidae, arose when it was very cool in terms of geologic time. Had it never gotten that cool I doubt that the exact same family would have arisen. And I think it even less likely that our specific species would ever have arisen. That's just because we are the product of a unique history and I think that if you change anything about that history the specific set of circumstances that led to our existence...well...you see.
However, now that we are here, we are extremely adaptable. Even before technology we lived in environments ranging from the equatorial tropics to the Arctic. We lived in rain forests. We lived in deserts. We lived on the tundra. Live generally as we know it has thrived under much warmer circumstances than we have now and under much warmer circumstances than we're going to have in 2100 if the projections are correct. I don't think the kind of temperature increase represented by even the upper end of the uncertainty range of the projections is going to kill the planet and I don't think it's something our species can't adapt to and thrive in.
I think there are bigger threats to the survival of our species than Climate Change.

I was not aware of that but the big thing is that we are here and we are extremely adaptable. We can obviously survive and even thrive in a variety of environments and that was the case even before we had technology. My understanding is that the belief is that there were people living in the Arctic 40,000 years ago. And, of course, people were living near the equator well before that.

from what we know about the position of that region during the time that our early ancestors evolved (before the Homo genus), the climate was more stable than the overall world average climate - the region has been largely subtropical for a few hundred million years if memory serves

now, we don't adapt our bodies - we just hit fast forward on the process with technology - and adapt our immediate environment (put an AC unit in the window)
The problem is that if the effects of climate change are adverse to the point that it require physical adaptations to survive them, we won't have time to do it because the changes won't be a as gradual as something like an encroaching ice age. So we'll have to deal with it through the use of technology and cooperation - I'm not sure we will be capable of that in ways that will allow us to thrive at our current levels. But our species will certainly survive (and we might come out the other side better for it)

Re: Beating Guam Guy At His Own Game
At some point the argument has to be as simple as "isn't it time we moved on anyway"
in regards to new energy and fuel sources
If money wasn't the single most important "thing" on earth (it is and I get that)
We could allow ourselves to actually entertain scientific development and growth in earnest
The question:
Why every building below 40 degrees N doesn't have a solar panel on it to this day... is shameful
We could NOT build the 300 M1 tanks the Military already DOESN'T want
and pay for that in 3 months
We're our own worst problem - that cannot be argued - regardless of which side of "science" you debate
and all the other stuff aside - we are ultimately our biggest problem... Even Jesus knew that
