That a lot info. My headHere's some paleoclimate stuff @Muttley000 that's interesting.
This is a graph showing the last five glacial & inter-glacial periods (including the one we're presently in).
The red line is the warmest period of this inter-glacial - The Holocene optimum, a period warmer than present.
Note that three of the four previous interglacials were warmer than The Holocene Optimum despite CO2 apparently only 280ppm.
The graph below shows CO2 (purple line) & temperature (blue line) levels over the geological timescale.
Note that there is no correlation between co2 levels & temperature.
The red line is the iceage temperature nadir. Note co2 levels when the planet went into iceages marked by the three red circles.
Red circle number 3, CO2 was around 4,500ppm, 11 x what it is today. Even CO2 at those levels couldn't prevent an iceage.
This next graph is interesting. The white boxes - A, B, C, D, & E, represent known Major reef building periods by calcifying organisms over the geological timescale.
Note box A & B in particular. Despite atmospheric CO2 levels above 5,000ppm in A, & as high a 4,000ppm in B, reef building organisms were able to calcify.
Box E represents the major reef building period of the corals we have today, the scleractinian corals, with CO2 at 2,000ppm.
Interesting is the prediction that co2 increases will cause ocean acidifciation, lowering pH & greatly affecting calcification. This record puts doubt on this theory & shows that upwelling is what controls ocean upper layer pH levels, not atmospheric CO2 levels.
@Ardeus,
I just have to ask the a few questions based on your various assumptions. Let’s say your understanding of climate change is correct and we have to act today…right this second. Guess what there are several facts that will get in your way.
Fact one: No government on planet Earth exists that has the will, money, science, man power or political currency to affect the massive change in direction you assert is necessary today or in the foreseeable future. There is no one body of political power that can bring about the rapid changes on a world-wide scale you assert are necessary. So really where is the solution to all this back and forth discussion?
Fact two: Even if you could build a coalition of the willing you would still need the science to actually know how to reverse climate change and have the technical expertise and infrastructure to accomplish the goal today. To this day no one has the ability to affect weather change by scientific manipulation. So, there is that problem. Not to mention there are as many theories about climate change and its source as demonstrated by the discussion of the “settled science” you so mystically believe in. Since no one can agree as to the problem the solution is just as elusive period. Let’s add to that the fact that many sources like wind power and solar actually require outside power sources and fossil fuels to get them to operate properly so they are still dependent on fossil fuels and its by products.
Fact three: This program would kill millions of people as they starved to death as you implemented a complete ban on fossil fuels and their use in all means of travel and agriculture. This would only leave the incredibly rich who can afford to adapt quickly to survive. Is that your end goal? Is that the solution you imagine? Economies would collapse, people would take to the streets like the Yellow Vests in France but on a global scale like you have never seen. I would suggest it would be more like the French Revolution when blood ran in the streets as anyone and everyone who was suspicious would meet Madam Guillotine again. Is that the outcome you would like? Chaos just total chaos with no one strong enough to control the situation and no buy in from the people of planet Earth.
Fact four: Emerging countries would be left out of the mix of survivors since they depend even more on the current energy sources available to them today just to survive in our global economy. They honestly don’t have a power grid that works reliably and in many parts of the world the only source is fossil fuel often brought in from out side the country. How about them? Is it a case of it just sucks to be you if you are one of the billions of people who are not in the elite?
Fact five: Battery powered cars, planes, buses, ships, and all types of locomotion still depend on fossil fuels to make the components, charge the batteries and deliver the products. And the current technology can only imagine the production of most of these necessary items. It is also a known fact that many of the batteries are a toxic waste that we are not even able to re-cycle at this time. So, what do we do with the technology until we can handle the waste? How many unintended consequences will we suffer by jumping to a very young and immature industry as our main source? Again, we are just now entering into the use of these energy sources and so far, the net impact is negative as far as the actual dependence on fossil fuels.
Fact six: Most countries are going away from nuclear power as a possible source since there is a problem with control and disposal of the waste generated. Yet, at this time this is actually the most developed and know alternative to fossil fuel for power generation. It is just not politically accepted because of the waste problem.
Fact six: Not one of the scientists, politicians, business leaders, government leaders or others has enough buy-in to actually stop using homes, computer, cars, planes, helicopters, ships, trains, plastics, or other fossil fuel defendant items to even act as anything less than a hypocrite. Just look at their consumption and fossil fuel carbon foot prints and stop lecturing the rest of us about how bad we are. Al Gore is one of the worst offenders as his carbon foot print makes hundred of people look like small little candles versus his rocket engine of consumption. Now that is an “Inconvenient Truth” if I have ever seen one. He is joined by the Hollywood elites who jet off to London on a shopping spree or down to Australia for a vacation in private jets. Then they have the temerity to lecture us through individuals who have bought their hypocrisy hook, line, and sinker. There is a reason they are called actors and not academics. Just let that thought sink in for a minute. It should a least make you squirm a little.
Fact seven: The global climate change is about money and political power and who will wield it for the next century period. A tax given to any government will be wasted through graft, waste, and outright ignorance as we have witnessed in all our time on planet Earth. This will only transfer wealth from those who generate it to those who will of course use it for their own purposes. Read history for a primer on what I am saying here and follow the money.
Fact eight: There are no human solutions to this problem. Yes, I agree with you our world is dying. But humans are powerless to prevent it. It is beyond our ability to control or command. Science does not even know how to ask the right questions when we are willing to spend $100,000 on a study to see if Sunfish get drunk. Yes, it actually happened Google it for yourself.
I believe there is a solution but people think Science is a religion and are consumed with worshiping at the altar of self-determination and self-interest. Many have bought the lie of survival of the fittest. People who think that they have the answers and ability to correct the path we are on if only we would give them all our money. Nothing is further from the truth. There is an answer but many are not interested in the actual truth in this situation. You don’t even consider the actual cost from beginning to end of your assumptions. This is why Science is a terrible religion because it offers no hope or solutions. It only offers doom and death. Sorry if millions or billions of us disagree with the assumptions.
P.S. I am still waiting for the Ice Age predicated as “settled science” since I was a teen in the 70’s. I can see by your picture you have no idea what I am referring to since you were not born yet. Live a few more years and get back to us. We will still be here God willing.
P.S.S. “There are three types of lies. Lies, danged lies, and statistics”. Samuel Clemens. Maybe he was on to something. He might have lived long enough to see the truth of it. I hope you live long enough to see the truth of it as well. Wishing you all the best. Try to find a more optimistic outlook and you will live longer and happier. When our time on Earth is done it is done and no Science can stop that truth. There is hope for a future and if you are willing and interested I would share it with you.
I commend you for acknowledging upfront that you have no empirical support for your beliefs about climate change, a very complex, very specialized, but well researched scientific matter. That’s more than what many folks are willing to admit. I do wish you’d take it one step further though, and realize that since you lack the requisite data (and/or likely the training to understand it), it makes absolutely no sense at all, and it is generally not in anyone’s best interest ever for folks to formulate, and certainly not to disseminate their own strongly held, but un or under-informed beliefs. That’s actually one of the great things about the scientific method, it seeks to minimize, to the greatest extent possible (this part is often admittedly difficult, willful work, as bias is ever present in all facets of our existence, and therefore as scientists, and as concerned citizens, we must strive to avoid it, and it is true, mistakes are sometimes made, but we are but human, after all), personal thoughts and wishes about empirical matters, and to emphasize the story the best available data is telling.
Without beating on your post much past the first few lines, I’d like to ask you just a few questions. Who have you asked to provide you data on climate change from 10k years ago? Were they researchers (preferably reputable climatologists, doctoral level experts focusing exclusively on the matter) with access to and/or knowledge of how to obtain said data sets at least? How do you know that what they provided you with was inaccurate? Are you trained in interpreting this sort of data? What caused you to reject it? Were there problems with the underlying model, the statistics used to interpret the data, or the raw data itself, and how did you know it? How do you know that 5, 10, 20, or 50 year climate spans are the best and indeed critical units to analyze the relevant historical data sets in? Or was it just that those numbers appear to have some face validity, and aren’t as abstract to you because they fall within our own anecdotal human experience (science doesn’t care about that, unfortunately). How do you know that comparing the end of the last ice age’s rate of climate change is the critical thing to look at to judge and predict our own era’s? There are many factors involved in this process, and again, while it may strike you as face valid to focus on the end of the last ice age, there are many relevant differences between then and now that make it a very poor comparison in myriad ways, not the least of which, we are certainly not in an ice age currently, so our decent into the ecological hellscape of the anthropocene is extremely unlikely to mirror the changes of that era. Sure, we can use such data sets to help build the climate models, but a straight comparison is, truly, a gross oversimplification, and a highway to the logical fallacies plaguing our current culture.
That is all to say, if you don’t understand something, and you know that don’t, isn’t it much better to rely on the fields experts than to invent your own take on the matter, or to say you are poking holes in something you don’t have an actual clue about? For example, you likely are not an expert on general problems with mitosis, or even more specifically on uncontrolled osteocyte division. Therefore, if you had severe bone pain, you’d probably ask your MD for help. If they told you that they feared you might have osteosarcoma, (uncontrolled osteocyte division, “bone cancer,” and an extremely malignant kind at that) instead of inventing hypotheses about the statistical odds of such a dx being accurate, and on the nature of the role of shortened telomeres in uncontrolled cellular reproduction, you’d likely seek an even more specialized expert medical opinion, that of an osteo-oncologist. From there, maybe you’d get another opinion (but with a tumor doubling time of 11 days, perhaps not), but if they concurred, you’d accept the facts as they presented them, and begin their recommended course of treatment, even though you don’t really understand the disease well at all, and don’t have the training to really do so at the cellular and genetic level, because you trust the experts, even though you know they don’t have all the answers about cancer yet either, you know they have a lot more knowledge than you do, and you want to live. Climate science isn’t really any different.
And btw, I picked your post, but this was generally an exercise in my frustration with many people’s spreading of misinformation both here and elsewhere. We can do so much better!
I can't keep doing this, and it's not why I come to R2R, but I appreciate the amount of time you spent formulating your well thought out post. The other side of the argument has not shown me (I am not saying it isn't out there somewhere because I am not a scientist, I am just a guy that runs a robotics integration plant) the data to show the rate of change in this small snapshot that is used today is the greatest it has ever been. Understand I am not arguing the earth is warming, or even at a quite interestingly quick rate. I was merely stating why I am unable to accept a comparison of a rate of change that has occurred in the last blink of time geologically and that humans are solely responsible. To answer one of your questions directly I have not asked anyone for the data, and if it exists I would think it would be cited often as it would be a pretty strong piece of evidence. As said I don't reject that the earth is warming, I currently reject the argument that human activity is the sole or majority driver.
While I have the training to know when someone is just saying what they “feel”, many folks unfortunately do not, and they subsequently adopt what they see as others presenting what they assume are equally valid hypotheses. I think that this means that you (and, again, many others) should stop opining baselessly about matters on which you have no expertise to base said opinion upon, (it’s destructive) and leave it to the experts to assess the situation, and/or acquire the requisite skill set to actually consume the available peer reviewed literature in a constructive and valid manner, and then spread the informed word.
