We Have Nothing to Fear about Global Warming Except for the Fear of Global Warming Itself

Introduction 

First I wish to apologize for not using the much more scientific term 'climate change' instead of the term 'global warming'. The reasons for this are simple. The climate has always changed throughout Earth's history. Thus, everyone believes in climate change. Also, the Earth has not warmed or cooled significantly since around the turn of the century, and those climate scientists and politicians who keep telling us to be alarmed, much prefer the term 'climate change', to keep from being embarrassed.

Enough having fun at the expense our beleaguered climate scientists.

Since my last post on global warming, not much has changed about what the climate data shows: The Earth is warming at a rate of less than 2C per century.

A warming of 2 to 3C might be better for humanity, so maybe we should be celebrating. 

What does the current data show?

I've looked at the temperature data from many sources, and as mentioned in the introduction, the actual data shows a warming at a rate of less than 2C per century.

And the climate models, which take many decades to verify, have mostly been wrong so far. Here's a telling graph that gives actual data compared with the predictions of 90 climate models:

 http://thefederalist.com/wp-content/uploads/2014/05/Climate-Model-Comparison.png

The actual data are the blue and green dots. The black dots are an average of the climate model predictions. The actual data shows about a 0.4C increase over the last 30 years, which extrapolates to about a 1.4C increase over a century.

According to this chart of actual satellite and surface temperature observations vs. what was predicted by 90 different climate models, 95 percent of models overestimated actual temperatures. 

So when you hear the, “95 percent of scientists believe in global warming” talking point, you can now reply with “95 percent of reality thinks your climate models are garbage." (Credit to Sean Davis for this creative reply).

And therein lies the real reason why so many global warming alarmists are so desperate to change the terms of the debate. Rather than discuss the actual science, they’d rather marginalize anyone who disagrees with their policy prescriptions. 

The global warming alarmists aren’t attempting to shut down debate because they’re worried the dissenters are wrong; the alarmists are attempting to shut down debate because they know their models are wrong, and they’d rather nobody focus on that inconvenient little fact. 

What should we tell the plants? 

Tell them that our scientists at the United States Environmental Protection Agency (the EPA) have declared that carbon dioxide is a pollutant. Tell the plants that the EPA must have forgotten what they learned in 9th grade biology about the Oxygen Cycle and how plants absorb CO2 and give off oxygen, which animals tend to breathe in on occasion. 

What should we do now? 

Don't give in to any of the 'carbon tax' proposals. And don't lose sleep over your 'carbon footprint'. 

But go ahead and support cost-effective conservation efforts, and support the reduction of real pollutants such as mercury and lead.

Thanks so much for your insights, Tim. People unfamiliar with modeling somehow think it will predict the future, not understanding all the variables. The hurricane models are a visible example of the limitations of prediction (look at where the hurricane hits within the comparison of the predictive models). Models are helpful. They are the best predictive guidelines that we have, but people have to realize their inherent weaknesses and the large margin of error. My understanding is that weather has so many variables that patterns are looked at over hundreds of years, not five or ten. This will play itself out and I don’t want to lose any friends over it, but thank you for having the courage to share information on this. I see Facebook friends joking that anyone who doesn’t believe in global warming is too stupid to understand, so you are right. No more arguments from them, just insults.

Is it possible to program benevolence into an AI?

Benevolence is really an emotion, just as are anger, enjoyment, and other emotions. 
We have no idea as to how to program a computer (or AI which is a computer program possibly controlling some hardware) to have feelings. We have no idea as to how to program a computer to be self-aware or to care about anything.
There is a debate about this. Some computer scientists think that we’ll eventually be able to program AI’s to have feelings and be self-aware and some computer scientists don’t think so.
And if they do become self-aware, would that be bad? More than a few scientists think so.
Stephen Hawking, for example, has stated: “I think the development of full artificial intelligence could spell the end of the human race.”
Bill Gates, the founder of Microsoft, is equally concerned: "I am in the camp that is concerned about super intelligence. First, the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well. A few deca…

Save us from Leftists

By definition, Leftists want the government to control much of their money and lives. Governments are run by politicians, which have a favorability rating around 15–20%. Who wants them to control the economy or our lives?

If you do, look around at the numerous countries that have tried this. They invariably get corrupt and their people become poor.

I’m not against programs that give money to parents to educate their children as they see fit. I’m also not against programs that give money to each of us to provide for medical expenses. But this money should go to all equally so that we have ‘equal rights before the law’.

If structured properly, these programs don’t allow Congress to control our lives because parents would be able to choose the school for their children.

And adults could choose their doctors and hospitals for them and their children.

Leftists such as United States Senator Elizabeth Warren, “Unveiled a proposal (in February 2019) outlining the Universal Child Care and Earl…

Will mankind survive overpopulation, resource shortage and climate change?

I’m going to reduce the anxiety in your life. Here’s how: Overpopulation is not a problemWe’re not running out of resources“Climate Change” may be disruptive, and it may even be better for humanity Let’s take these one at a time. Overpopulation In 2017 world population is about 7.5 billion. Here is a UN graph of the projected population until 2100:

So it seems Earth’s population will top out this century between 9 to 10 billion people. Modern countries can easily feed, provide clothing and housing, etc., to its citizens. Developing countries have a problem because their governments are corrupt and don’t allow its citizens freedom, especially free markets. As countries modernize they get richer. Notice the growth of China, for instance, because its government has been allowing free enterprise. Natural Resources Reports of running out of natural resources have appeared for decades and maybe a century ago. Instead we’re finding more and more natural resources. Fracking has allowe…
