Classical physics of the past 300 years is a better example. At a couple of points the physics community thought they had it all figured. First with ether and later without. If consensus was science there would be no relativity or quantum mechanics.Not sure where the history lessons started but why not. I think a lot of this debate over the notion of the flat earth is about an oversimplification of the subject and some lack of knowing basic history. The purpose of Columbus' was to discover a easier way to get to Asia, specially India by sailing west around the world. Clearly he and others at the time had a basic understanding that the world was indeed round because otherwise why would they have sailed in the opposite direction of their destination?
However, it wasn't exactly a solid fact and Columbus had no idea about the actual size of the Earth. That's why all this stuff got tagged Indian. He thought he was in India but was actually closer to Indiana. I'm kind of joking here, there seems to be some fuzziness over exactly when he realized that he hadn't reached Asia or India but he clearly was expecting to reach Asia and not a new part of the world because of he well off estimation of the size of the Earth. But he and others did realize soon enough that this was a new area of the world to Europeans and it wasn't long after that the true size and spherical shape of the Earth were confirmed facts.
My understanding is this is not the centerpiece at all. I've heard from a geologist before that there's significant evidence that without any influence from man, we would likely be heading slowly towards the beginning of another ice age. The important part isn't just how hot it is now, but how how hot it is compared to 10 years, 20 years, 100+ years ago. We've only been using oil an industrial sense since the 1860s. Additionally, our population is exponentially higher than it was then also. Climate change prior to that we likely had a minimal effect on. Climate change is normal and happens all the time. Climate change happening as rapidly as it has been over the past 150 years is what's the problem.The centerpiece of the Global Warming debate revolves around the question as to whether the Medieval Warm Period was warmer than today. Mann, Bradley and Hughes published papers based upon tree ring and ice core samples which concluded modern temperatures are warmer. A controversy exists however over this study. Peer review is a cornerstone of the scientific method whereas scientists are expected to publish their data and methodology so as to allow other scientists to verify their results. Mann refused to do this.
Source? My understanding of Greenland's name is that it was an early example of marketing, trying to attract settlers when the reality was it was ice everywhere. It's been a long standing historical irony. The same way we call Native Americans Indians. They're not actually from India.It should also be noted that Global Warming as a nom de plume has fallen from favor substituting Climate Change instead.
t should be noted that the Vikings named Greenland because of its lush vegetation and relatively mild climate during this warming period which bears little resemblance to the icy rock Greenland is today.
Just, no, it doesn't. Just because it was warmer (naturally) in Earths history (which is obvious) in no way means humans aren't causing it now. Has it ever dawned on you it could be both? Of course not, that would be reasonable.The centerpiece of the Global Warming debate revolves around the question as to whether the Medieval Warm Period was warmer than today

This suggests that the Medieval Warm Period was in fact warmer than today supporting MIT's Atmospheric physicist Dr. Richard Lindzen assertion that todays weather patterns fall within normal weather fluctuations.
Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation Special Report of the Intergovernmental Panel on Climate Change Extreme weather and climate events, interacting with exposed and vulnerable human and natural systems, can lead to disasters. This Special Report explores the challenge of understanding and managing the risks of climate extremes to advance climate change adaptation. Weather- and climate-related disasters have social as well as physical dimensions. As a result, changes in the frequency and severity of the physical events affect disaster risk, but so do the spatially diverse and temporally dynamic patterns of exposure and vulnerability. Some types of extreme weather and climate events have increased in frequency or magnitude, but populations and assets at risk have also increased, with consequences for disaster risk. Opportunities for managing risks of weather- and climate-related disasters exist or can be developed at any scale, local to international. Some strategies for effectively managing risks and adapting to climate change involve adjustments to current activities. Others require transformation or fundamental change. Source

Canadian geologist Stephen McIntyre literally had to sue the publishers of Mann's paper in order to get the data and found Mann had cherry picked tree core samples. Roughly 150 samples were obtained but Mann based his research on 10 - 12 samples which supported his hypothesis and ignored the 90% samples which did not support his hypothesis. This is the same Mann who was exposed in the Climategate scandal as a very shady character.

Only thing worse than those who refuse to admit that they're wrong are those who try to deflect away from their wrongness.
All evidence points towards natural causes to our weather patterns. Attempts to prove scientifically that our weather is unusually warm have failed. The poles are not receding; the population of polar bears has doubled over the last 30 years. What can you put on the table that proves conclusively that the ecology of the earth is in danger?Just, no, it doesn't. Just because it was warmer (naturally) in Earths history (which is obvious) in no way means humans aren't causing it now. Has it ever dawned on you it could be both? Of course not, that would be reasonable.
The debate is on how much of an impact humans are having on the Earths natural cycle. It's about destabilization altogether, not just about it getting colder or hotter. It's about human activity possibly triggering extremes in the global climate, artificially.
Even if this is true (I don't care if it is) why should this be noted? Everyone is aware of the natural cycles of the Earth. That's not even in question, man.
There is a great reason why, too, as it's all about the destabilization of the Earths natural cycles. After all we don't want to trigger the Earth negatively for human life) in either direction. Balance.
Irrelevant and this is the same guy that also claimed cigarettes had little to know impact on lung cancer. He also knows we have to monitor our impact on the global climate which you seemed to not know coming into this thread. This guy has been wrong more than a few times and the fact he has received money from people that benefit from no change being implemented doesn't help his case, and you're not helping yours, either. You called a few people here uneducated yet you lack the basic concepts of this entire debate. It's like you're making up the debate in your own mind...lol.
I'm worried it's this kind of logic that is the crux of many anti-warmer beliefs. That because you can find a single solitary instance of something outside of the norm, the norm is therefore not the norm, and "anything is possible!". Just because you find an article here or there that claims to disprove global warming does not mean global warming has been disproven.My Grandfather smoked cigars everyday and died at 95. Cigarettes have little impact on lung cancer in some individuals (fact) while having a major impact on others.
You keep saying things that can be disproved, then you don't address the response in an intellectually honest way. I mean let's look at the list:All evidence points towards natural causes to our weather patterns. Attempts to prove scientifically that our weather is unusually warm have failed.

Cancers and Lung Cancer specifically seems to run in families. Cigarettes do not cause cancer otherwise everyone who smokes would get cancer. I think it is more accurate to say smoking cigarettes increases the odds of getting lung cancer in those persons with a predisposition to lung cancer. Knowing whether one has that predisposition is difficult to access and smoking is associated with other illnesses so in general it is wise not to smoke however you cannot say conclusively that smoking will harm a specific individual.I'm worried it's this kind of logic that is the crux of many anti-warmer beliefs.

Do you feel there is a consensus that cigarettes cause lung cancer?

Thank you for honestly answering this question and not just deflecting or answering with another question.Cigarettes do not cause cancer otherwise everyone who smokes would get cancer.
You are saying I can be disproved; have at it.You keep saying things that can be disproved, then you don't address the response in an intellectually honest way. I mean let's look at the list:
-You claim there is more pollution today than in the 1800s, but only focus on pictures and accounts of cities. We've stated pollution is more than just cities AND shown how places in China and India are just as awful as London and NYC used to be. Not counting that, there are far more people on earth now polluting so the total sum is much higher. I mention how deforestation is ocean pollution is far higher than it was in the 1800s. You ignore all of this and show us more pictures of polluted 1800s cities.
-You mention cow methane having a bigger impact than cars, while ignoring the fact that there are MORE cows now AND cars polluting in addition to that. Your own logic doesn't hold here.
-You mention how removing all CO2 from the atmosphere will cause life to cease to exist, as though this was somehow a risk we were facing, nor do we even have technology that could remotely accomplish this. This feels like a total distraction to the conversation.
-You claim Greenland was a lush jungle when it was named, but provide no evidence of this. It's common knowledge Greenland was full of ice when it was named, the burden of proof is on you to prove otherwise.
-You're pointing to a grandfather living to an old age as proof cigarettes don't kill everyone. So what? Cigarettes have more additives Maybe your grandfather would have lived to 105 if he didn't smoke. Intense radiation doesn't kill everyone at the same rate either, that doesn't mean it's not harmful as shit. This feels like misdirection again.
-You're claiming the Middle Age warming is the centerpiece of the global warming argument. We've flat out stated it's not. While it's an argument someone has no doubt made, the measurements of temperatures across the globe for the past 100 years are the CENTERPIECE of the argument.
Your posts have a clear trend of making unsubstantiated claims, then intentionally not addressing them honestly. Want us to take your seriously? Provide a source showing there is more forest now than in the 1800s. Provide a legitimate source stating that Greenland was full of lush greenery at the time it was named and not ice. Provide a source explaining why burning 950 billion barrels of oil does NOT impact the climate. If you can't do these things, you're just coming across as an advanced troll, there's no point in even replying to what you're saying if you're not willing to be intellectually honest about what you're saying.
Hey look! 26 pages in and still going! I wonder what the record for a flamewar on this forum is.

What do you define pollution as?CO2 is not a pollutant.
CO2 is not a pollutant.
thejokker said:Disprove that 19th century industrial cities were not vile, polluted, ceasepools matching any modern third-world emerging country. It should be easy; right?

In high enough levels it is. No one even disputes that.
I wonder what tune you'll be singing
Absolutely correct.
Both my parents smoked all their lives and did not get cancer.
Also, if smoking caused cancer we would see the lung cancer rates decreasing in accordance with the decrease in people who smoke. Instead LC rates are the same or increasing while the smoking rates have dramatically decreased over the last 20 or so years.
^ orly?
The entire warmer movement is based on fabricated studies and peddled by politicians and idiots. The fact is, there isn't a consensus that man made climate change poses any immediate danger. Is it any wonder that the world's leading economies (china, Germany) skipped on obama's UN climate change summit?
most people do not give a rat's behind about this absurd climate change religion that you guys keep trying to shove down our throats.
What do you define pollution as?
noun
The presence in or introduction into the environment of a substance or thing that has harmful or poisonous effects
