The Earth is not warming up. The White Cliffs of Dover stagger into the sea and cause a rise in sea level. Global warming contributes to the growth of the Antarctic ice sheet.
These are some of the skeptical allegations repeated by Republicans in the US Science, Space and Technology Committee yesterday. Legislators have intermittently undertaken research that questions mainstream climate science at a hearing on how technology can be used to combat global warming.
A senior climate scientist who spent most of the two hours in front of the panel on correcting misrepresentations to the hearing should focus on how technology could be used to adapt to climate change. But the hearing often turned to the basics of climate science. Many of the questions from Republicans and Democrats have been equally addressed to Philip Duffy, President of the Woods Hole Research Center in Massachusetts and former senior advisor to the US Global Change Research Program
Rep. Dana Rohrabacher (R-CA) said he was bothering that established climate research was no longer questioned by the committee, which accused federal climate researchers of being climate-damaging and having their records summoned.
"I am a bit disturbed by, # 1, over and over again, I hear," Never say if humanity is the main cause of temperature change and changing climate, "he said a little disturbing, if we are constantly struck in our heads at a science committee meeting, if we are all basically open to different viewpoints. "
Rep. Lamar Smith (R-TX), chairman of the committee, walked in the protocol published in The Wall Street Journal claiming that sea levels are not rising, a view that rejects thousands of scientific studies.The piece was written by Fred Singer with the Heartland Institute in Chicago, Illinois, which promotes the rejection of mainstream climate science.
"In order to address the challenges of climate change, we must first examine the existing uncertainties acknowledge that, "Smith said in his introductory remarks. "Then we can trust that we can use innovations and technology to mitigate the adverse effects of climate change."
At one point, Smith showed a decline of two graphs, which, he said, demonstrated sea-level rise, unlike the sharp increase in fossil fuel consumption. When Smith pointed out that sea-level rise rates had only increased marginally compared to fossil fuel consumption, Duffy pointed out that his map was from a single gauge station near San Francisco and sea levels were rising at different rates around the world , Smith showed no rising atmospheric CO 2 levels or temperatures, both of which have risen steadily in recent decades as emissions have increased.
Every time you have this soil or rock or whatever in the seas that force the sea level to rise, because you now have less space in these oceans, because the ground is moving upwards.
"The rate of global sea-level rise has accelerated and is now four times faster than 100 years ago," said Duffy Smith in response to the charts.
"Is this graphic inaccurate?" Smith asked, "It's accurate, but it does not represent what's happening globally, it represents what's happening in San Francisco," Duffy said.
Rep. Mo Brooks (R-AL) interviewed Duffy on the factors that contribute to sea-level rise, pointing out that land subsidence plays a role, as does human activity.
Brooks then said that erosion plays a significant role in seagoing vessels. Level rise, which is not accepted by the mainstream climate researchers. He said that the Californian coast and Dover's White Cliffs plunge into the sea every year, contributing to sea-level rise. He also said that Schlick, which washes into the ocean from the world's major rivers, including the Mississippi, the Amazon and the Nile, is contributing to sea-level rise.
"Every time you have this soil or rock or whatever is dumped in the oceans, it forces you to climb the sea level, because now you have less space in these oceans because the ground is moving," Brooks said ,
Duffy replied, "I'm pretty sure time scales on humans, these are tiny effects."
Brooks added that Antarctic ice is growing. This was so a few years ago, and scientists say it does not refute the theory of global warming, as several factors affect the melting rate of the Arctic and the Antarctic.
"We have satellite images that document a shrinkage of the Antarctic ice sheet accelerating this shrinkage," said Duffy.
"I'm sorry, but I do not know where to get your information, but the data I've seen suggests -" said Brooks.
Duffy replied, "The National Snow and Ice Data Center and the National Aerospace Authority."
"Well, I have a NASA base in my district, and apparently they tell you one thing and I do another thing," said Brooks. "But there are many studies that have shown, with respect to the Antarctic, that the entire ice cover, especially over the mainland, is increasing and not decreasing, so you could argue another argument if you are talking about Greenland or the Arctic."
Earlier this year, NASA researchers found that Antarctic ice loss has increased over the last decade. By and large, sea ice extent at both poles reached a record low last year. Scientists are trying to better understand the changes in the Antarctic, as much of their ice is land-based, which could mean that it could raise sea-level rise worldwide as it melts.
Rep. Bill Posey (R-FL) said scientists had said in the 1970s that the Earth is cooling, a popular discussion point for climate skeptics and the subject of a fake Time title that has become a meme. Duffy corrected him, saying it was essentially a runaway position at the time, and scientists had long ago discovered that humans were warming the planet.
Posey also asked how carbon dioxide in permafrost could be trapped in the periods before humans exist. Duffy told him it was undecomposed organic material. Human activity is now helping the Arctic heat and thaw the soil and release the carbon into the atmosphere, Duffy said.
Posey then asked for theories that relate to warming, which is beneficial for habitats and humans.
say to people who theorize that when the Earth heats up further, the Earth returns to its normal temperature? "Asked Posey."
"If you want to characterize a temperature above today's temperature as normal, you can do that, but that does not mean we want to live on a planet," said Duffy, 19659008] "I do not want to be philosophical become; I try to stay here on science, "Posey said.
" I do not become philosophical; I'm getting extremely practical, "said Duffy," I'm extremely handy – if we let the planet get 2 or 3 degrees warm, we'll have tens of meters of sea-level rise, and the community I live in will essentially cease to exist.
Posey replied, "I do not think anyone denies that the earth is getting warmer; I think what is not clear is the exact amount of who has caused what, and that is, I think, where we are trying to go with this committee. "
