Scientists and Global Cooling

Scientists are usually smart and correct but can also be wrong more often than they'd care to admit. 



Don't Tell Anyone, But We Just Had Two Years Of Record-Breaking Global Cooling


Inconvenient Science: NASA data show that global temperatures dropped sharply over the past two years. Not that you'd know it, since that wasn't deemed news. Does that make NASA a global warming denier?

Writing in Real Clear Markets ,  Aaron Brown looked at the official NASA global temperature data and noticed something surprising. From February 2016 to February 2018, "global average temperatures dropped by 0.56 degrees Celsius." That, he notes, is the biggest two-year drop in the past century.

Read the rest of the article H E R E  :  Hiding the Evidence


My point is that statistical cooling outliers garner no media attention. The global average temperature numbers come out monthly. If they show a new hottest year on record, that's a big story. If they show a big increase over the previous month, or the same month in the previous year, that's a story. If they represent a sequence of warming months or years, that's a story. When they show cooling of any sort—and there have been more cooling months than warming months since anthropogenic warming began—there's no story. -- Aaron Brown




Cooling for 2 Years

Science Matters: Paris Climate Agreement

What's in the Paris Agreement?
* Grand pronouncements, VAGUE specifics

* $100 trillion spent for only 0.3 Farenheit temperature reduction by end of the century


* Watch the short video below for a much better, measurable SOLUTION to global warming



ETA:
On August 4, 2017, the Trump Administration delivered an official notice to the United Nations that the U.S. intends to withdraw from the Paris Agreement as soon as it is legally eligible to do so. The formal notice of withdrawal cannot be submitted until the agreement is in force for 3 years for the US, in 2019. In accordance with Article 28, as the agreement entered into force in the United States on 4 November 2016, the earliest possible effective withdrawal date for the United States is 4 November 2019. If it chooses to withdraw by way of withdrawing from the UNFCCC, notice could be given immediately (the UNFCCC entered into force for the US in 1994), and be effective one year later. - wikipedia

Science Matters: Temperatures Rising?

NOPE, temps are not rising.  Planet Earth is actually on course for a little "Ice Age" in the next few years.  Surprise, Surprise.  Read all about it below:





Ever since December temperatures in the Arctic have consistently been lower than minus 20 C. In April the extent of Arctic sea ice was back to where it was in April 13 years ago. Furthermore, whereas in 2008 most of the ice was extremely thin, this year most has been at least two metres thick. The Greenland ice cap last winter increased in volume faster than at any time for years.
As for those record temperatures brought in 2016 by an exceptionally strong El Niño, the satellites now show that in recent months global temperatures have plummeted by more that 0.6 degrees: just as happened 17 years ago after a similarly strong El Niño had also made 1998 the “hottest year on record”.
This means the global temperature trend has now shown no further warming for 19 years...

Research shows a natural cooling cycle that occurs every 230 years began in 2014 and will send temperatures plummeting even further by 2019.
Scientists are also expecting a “huge reduction” in solar activity for 33 years between 2020 and 2053 that will cause thermometers to crash.
Both cycles suggest Earth is entering a global cooling cycle that could have devastating consequences for global economy, human life and society as we know it.
If predictions of the world-wide big freeze come true, the plot to 2004 film The Day After Tomorrow would not be far from reality during winter. ...

Science Matters, Part 4: Scott Adams of DILBERT fame is a Sceptic

Scott Adams is a climate denialist.  His cartoon, and his very well-written essay need to be re-shared here, there, everywhere:





by Scott Adams


I don’t know much about science, and even less about climate science. So as a practical matter, I like to side with the majority of scientists until they change their collective minds. They might be wrong, but their guess is probably better than mine.
That said, it is mind-boggling to me that the scientific community can’t make a case for climate science that sounds convincing, even to some of the people on their side, such as me. In other words, I think scientists are right (because I play the odds), but I am puzzled by why they can’t put together a convincing argument, whereas the skeptics can, and easily do. Shouldn’t it be the other way around?
As a public service, and to save the planet, obviously, I will tell you what it would take to convince skeptics that climate science is a problem that we must fix. Please avoid the following persuasion mistakes.
1. Stop telling me the “models” (plural) are good. If you told me one specific model was good, that might sound convincing. But if climate scientists have multiple models, and they all point in the same general direction, something sounds fishy. If climate science is relatively “settled,” wouldn’t we all use the same models and assumptions?
And why can’t science tell me which one of the different models is the good one, so we can ignore the less-good ones? What’s up with that? If you can’t tell me which model is better than the others, why would I believe anything about them?
2. Stop telling me the climate models are excellent at hindcasting, meaning they work when you look at history. That is also true of financial models, and we know financial models can NOT predict the future. We also know that investment advisors like to show you their pure-luck past performance to scam you into thinking they can do it in the future. To put it bluntly, climate science is using the most well-known scam method (predicting the past) to gain credibility. That doesn’t mean climate models are scams. It only means scientists picked the least credible way to claim credibility. Were there no options for presenting their case in a credible way?
Just to be clear, hindcasting is a necessary check-off for knowing your models are rational and worthy of testing in the future. But it tells you nothing of their ability to predict the future. If scientists were honest about that point, they would be more credible.
3. Tell me what percentage of warming is caused by humans versus natural causes. If humans are 10% of the cause, I am not so worried. If we are 90%, you have my attention. And if you leave out the percentage caused by humans, I have to assume the omission is intentional. And why would you leave out the most important number if you were being straight with people? Sounds fishy.
There might be a good reason why science doesn’t know the percentage of human-made warming and still has a good reason for being alarmed. I just haven’t seen it, and I’ve been looking for it. Why would climate science ignore the only important fact for persuasion?
Today I saw an article saying humans are responsible for MORE than 100% of warming because the earth would otherwise be in a cooling state. No links provided. Credibility = zero.
4. Stop attacking some of the messengers for believing that our reality holds evidence of Intelligent Design. Climate science alarmists need to update their thinking to the “simulated universe” idea that makes a convincing case that we are a trillion times more likely to be a simulation than we are likely to be the first creatures who can create one. No God is required in that theory, and it is entirely compatible with accepted science. (Even if it is wrong.)
5. Skeptics produce charts of the earth’s temperature going up and down for ages before humans were industrialized. If you can’t explain-away that chart, I can’t hear anything else you say. I believe the climate alarmists are talking about the rate of increase, not the actual temperatures. But why do I never see their chart overlayed on the skeptics’ chart so we can see the difference? That seems like the obvious thing to do. In fact, climate alarmists should throw out everything but that one chart. 
6. Stop telling me the arctic ice on one pole is decreasing if you are ignoring the increase on the other pole. Or tell me why the experts observing the ice increase are wrong. When you ignore the claim, it feels fishy.
7. When skeptics point out that the Earth has not warmed as predicted, don’t change the subject to sea levels. That sounds fishy. 
8. Don’t let the skeptics talk last. The typical arc I see online is that Climate Scientists point out that temperatures are rising, then skeptics produce a chart saying the temperatures are always fluctuating, and have for as far as we can measure. If the real argument is about rate of change, stop telling me about record high temperatures as if they are proof of something.
9. Stop pointing to record warmth in one place when we’re also having record cold in others. How is one relevant and the other is not?
10. Don’t tell me how well your models predict the past. Tell me how many climate models have ever been created, since we started doing this sort of thing, and tell me how many have now been discarded because they didn’t predict correctly. If the answer is “All of the old ones failed and we were totally surprised because they were good at hindcasting,” then why would I trust the new ones? 
11. When you claim the oceans have risen dramatically, you need to explain why insurance companies are ignoring this risk and why my local beaches look exactly the same to me. Also, when I Google this question, why are half of the top search results debunking the rise? How can I tell who is right? They all sound credible to me.
12. If you want me to believe warmer temperatures are bad, you need to produce a chart telling me how humankind thrived during various warmer and colder eras. Was warming usually good or usually bad?
You also need to convince me that economic models are accurate. Sure, we might have warming, but you have to run economic models to figure out how that affects things. And economic models are, as you know, usually worthless.
13. Stop conflating the basic science and the measurements with the models. Each has its own credibility. The basic science and even the measurements are credible. The models are less so. If you don’t make that distinction, I see the message as manipulation, not an honest transfer of knowledge.
14. If skeptics make you retreat to Pascal’s Wager as your main argument for aggressively responding the climate change, please understand that you lost the debate. The world is full of risks that might happen. We don’t treat all of them as real. And we can’t rank any of these risks to know how to allocate our capital to the best path. Should we put a trillion dollars into climate remediation or use that money for a missile defense system to better protect us from North Korea?
Anyway, to me it seems brutally wrong to call skeptics on climate science “anti-science” when all they want is for science to make its case in a way that doesn’t look exactly like a financial scam.* Is that asking a lot?
People ask me why I keep writing on this topic. My interest is the psychology around it, and the persuasion game on both sides. And it seems to me that climate scientists are the Hillary Clinton of scientists. They think facts and reason will persuade the public. Even though science knows that doesn’t generally work.
* Or a Chinese hoax. They look similar.

Science Matters, Part 3: What IS the Scientific Method?

FYI:  How to fairly assess what any Scientist says or claims --

Identifying 8 necessary criteria for a work to be considered useful science:



What is the “Scientific method”?
March 1, 2017's March for Science calls for “robustly funded” science and “political leaders and policymakers to enact evidence-based policies in the public interest.”  But is this just an attempt to dress up the marchers’ political beliefs as science? And what do they mean by science?
Fortunately for those who care, there is a remarkable level of agreement in the writings of scientific pioneers such as Francis Bacon, Isaac Newton, and Benjamin Franklin on the nature of the scientific method. That agreement is also reflected in the definition provided by the Oxford English Dictionary.
We have expanded on the established definition and identified eight necessary criteria for a work to be considered useful science. The criteria include objectivity and full disclosure. We expect that most scientists would agree with these criteria as obviously true and important.
The pioneers of science charted the way by describing how to comply with the criteria. To be objective, according to Newton, the study should compare all reasonable hypotheses by using a fair and balanced experimental design.
We have summarized the eight criteria on a one-page checklist (available at guidelinesforscience.com  ). You can easily refer to it to assess whether something you are looking at is a work of science. By using the checklist, you do not have to depend on an authority to tell you “this is what the science says.” Knowing and agreeing with the criteria in the checklist does not help. To be useful, the checklist must be used.
The checklist is concerned only with the scientific method, so one does not need to be an expert in the field or topic to use it. In fact, experts may have difficulty rating the scientific compliance of works in their own field.  They are likely to be biased against findings that challenge conventional wisdom.
We found that the ratings of raters who did not use the checklist were unreliable. Their ratings differed substantially from those derived using the checklist. When faculty and students raters used the checklist, their ratings were remarkably consistent. The checklist is available at guidelinesforscience.com .
The checklist is badly needed. One cannot rely on the fact that a purported discovery was published in a high-status scientific publication. When we used the checklist to rate papers published in leading scientific journals, we found less than one percent of them to be compliant with the scientific method.
We suggest that you try out the checklist at the March for Science rallies. Show your respect for the scientific method and, as Newton emphasized, be willing to consider alternatives. Be fair in evaluating alternative hypotheses. You have to ask yourself the question, “Can I imagine any evidence that would prove my favoured hypothesis is wrong?” If you can’t, you are not approaching the subject with an open mind. You also fail Newton’s criteria for understanding science.
Speakers should comply with science. Listeners should be respectful and request of the speakers, “Please show us that you have complied with science.” It’s not enough for them to say that they have followed the scientific method.
Progress in all fields relies on the scientific method. Science is a never-ending, never-settled process.
Voting has no place in science. Scientific laws always eventually prevail over the political laws created by our elected officials.

The March for Science should not simply be another way for us to express our opinions. It should not be an effort to pressure scientists and voters to agree with us. The scientific method is the best way we have of engaging in factual disputes.

Science Matters According to Gilligan

Science Matters, Part 1

A Gilligan's Island fan thought that Science matters as evidenced by the picture below during a recent Earth Day event attended by our neighbour.  


Earth Day 2017 coincided with the Science March held in many places.  IMO, the march was just another opportunity for Leftists to get world-wide (free) coverage as they demean the POTUS;  and flex the muscles of their superior brains as we ignorant, average folk shake in our non-designer boots.  Okay, I admit to being ignorant on many Science/Environmental issues, but information is out there.  Fact is, there is way too much information on this divisive subject. Thus, I appreciate short articles that get to the heart of the matter. Below is an excerpt of one.  BOLD means a link for the source.




Green Energy is Inefficient
Climate change and renewable energy is one of the chief causes of the Science March, championed by Bill Nye and others. The march was deliberately scheduled to take place on Earth Day, when people are supposed to demonstrate their support for the environment by turning all their lights on...
Yet many of the fossil fuel alternatives championed by the eco-warriors are woefully inefficient. Wind farms in particular are a poster child for wastefulness, operating at 90 percent capacity or above for just 17 hours a year .  Solar energy is another shocker – according to electrical engineering professor Petr Beckmann,  it would take 1,000 hours of pure sunshine for a 15-square inch solar panel to generate the same amount of energy as a single lump of coal. 
In the U.K., vast sums of money have been poured into green energy schemes, only to disappear  after the companies that took advantage of government spending either went into administration or failed to deliver. 
Another problem for environmentalists:  wind turbines have killed more birds of prey  like eagles, raptors, and kestrals than deliberate shootings and poisoning.
