Do you believe the activities of humans are contributing to global warming?

154

Are we humans doing things to our planet that is causing it to become dangerously warm? Or it just another weather cycle that has nothing to do with humans? We realize this is a controversial subject, so if you choose to comment, keep it civil and constructive. No name calling. Educated opinions invited. Uneducated ones are not.

It may take a moment for the poll to load, so please stand by.

Humans have always had an effect on our environment. That being said, the effect has always been temporary. The amount of power in humans is small but the power of nature is just awesome.

Interior earth temperature is about 11000 deg F. The highest air temperature ever recorded is 134 deg F. A cooler object can’t heat up a warmer object.

Absolutely, without a doubt. Whether you measure out atmosphere in ppm or mg/L, the problem is well established. I often opened lectures with the observation that “There are 6.5 billion persons living on this planet. Tonight, by midnight, 4 billion must go. However, it must be the right 4 billion so I will begin picking after the first class break.” After due discussion, folks began to recognize just how intense and desperate this problem actually has become. Short of the story….there is nothing we can do. Its already loo late.

Patrick Moore would have fun sitting in your class Donn, but then he wouldn’t get in the door, your message and his are totally opposed – his based on science yours based on a job to spread IPCC propaganda to a vulnerable audience and get paid for it.

On a recent trip to Alaska we toured a couple of glaciers. The ranger giving the tour said the glacier was disappearing about 75 feet per year do to global warming. I ask how long have they been recording the receding glacier, he stated since 1760 it has lost between 50 and 75 feet per year. Now I can only assume the early frontier people were driving non emission controlled F350’s dumping CO2 all over our planet. The facts don’t line up with man contributing to global warming when you look at the history of the earth’s climate.

Glacier National Park has been warning about the coming disappearance of the glaciers by posting signs around the park that say “Gone by 2020”.

Actually, in recent years the glaciers have begun expanding again, and park officials have been discreetly removing the ominous signs and language from their brochures.

Ya, 100 years ago a very large ship hit one of hundreds of icebergs drifting in the north Atlantic due to a massive and unusual proliferation of them at that time.. Big loss of life that one. Not much at the time to blame on man made CO2 -was there?
Where I live in Alberta Canada the house here was under a sheet of ice some scientists claim was half a mile deep. What happened? No humans driving gas guzzling SUV’s to cause that., and today potatoes, carrots and cactus grow like crazy here.

The premise that CO2 is the major driver of man-made global warming is false. Water vapor is the major greenhouse gas. Increases in temperature results in increasing CO2, not vice-versa. It is a fact that the greenhouse effect of CO2 is logarithmic, not linear or exponential. This means that it takes a tremendously greater increase in CO2 concentration for each successive degree of heat due to CO2. At our current concentrations of about 400 ppm, the power of CO2 to increase temperature is almost entirely used up. It is only possible for CO2 to increase global warming by about 0.2 degrees C more, no matter how much higher CO2 concentration rises.

Global cooling will kill us all. No, acid rain will kill us all. No, a hole in the ozone layer will kill us all. No, global warming will kill us all. No, climate change will kill us all.

The “science” was “settled” on all of the above.

But the solution is simple. More taxes. And funding for the “scientists” to prove the theories they formulate before even beginning to research.

If those who voted yes truly believe that humans are the reason for global warming, and you answered this question on an RV website, you should quickly sell your rig and help stop the earth from warming. You will open up that many more sites too!

Regardless of where you fall on this discussion, be aware of one thing. We are not destroying the earth! Mother Earth will be just fine. Humans may not be able to live here, but the world will go on.

I firmly believe in natural (not human induced) historical climate oscillations and I believe that we are now going into a period that repeats every few hundred years called a “Grand Solar Minimum”. I also believe that “Global Warming” is a political issue being hyped solely for the benefit of the minority left wing to solicit sympathy and support.

I have lived in Florida for 64 years and I know the weather has changed, it is getting hotter, a lot hotter. We used to have real winters, sometimes with light snow.

In the summer we had rains for around 30 minutes every day at 4pm. Not anymore.

High tides are much higher now than when I was young.

Our springs are running dry.

I am sure there is more evidence than just this but many people don’t care. Many feel the best way to handle an issue is to ignore it, not to explore it. I don’t.

I’m shocked at how many drank the Kool Aid and became drunk. Al Gore is laughing all the way to the bank daily. Send me a check and I’ll plant a tree for you. Every one needs something to do and those with nothing jumped on this bandwagon of global warming until that came up short and now it is climate change. Of course it changes, has for billions of years and will continue.
Drop me a note for the address to send that check. I have a lot of ground to add trees on.

Contributing or creating ? A huge difference. A stacked deck question. If and until all the rest of the industrial countries deal with their pollution ( Hydrocarbons, NOx and CO) as well as the USA did theirs, then the USA should do NOTHING. I am so sick of globalist claiming that it is all the fault of people when the data is sketchy at best.

You can choose either to believe fossil fuel companies, committed to their own profit – and nothing else – or the organization founded in 1845 and committed to the truth – and nothing else:

Sorry, this article is not empirical proof of anything. The author, Shannon Hall, is a writer, not a scientist for one thing, and when she tries to cite a quote starting with “They said something like…” that holds no water in my mind. Climate changes indeed, I agree…but is it man-made or natural, we just don’t know because of the lack of recorded history. 150 or so years is not enough time for conclusive scientific evidence.

There are a few things I don’t hear deniers saying. At the risk of inciting backlash from those who prefer to stick to their own opinions, preferring not to consider evidence, here goes. Disclaimer: While I have participated in science as a student and as a technician, I am not a climatologist and unlike them, I have not spent my entire professional life gathering ice, soil and tree cores, pored over temperature records, developed weather and climate computer models and tested them against historic records, etc, so I cannot join the overwhelming majority who say without a doubt that human activity has caused the fastest rise in atmospheric and oceanic temperatures in all of *human* history or human pre-history. I do know a couple of simple facts however:

When I park my car in the sun with the windows closed, it heats up a great deal more than when I leave the windows open. This is an example of the “greenhouse effect”. Heat is delivered directly to the Earth from the sun in the form of light at the infrared end of the spectrum. The rays strike everything – the roof of the car, air molecules, everything – and whatever is struck absorbs some heat energy. When the car’s windows are open the heat energy is free to radiate back out of the car. When the windows are closed something interesting happens; a significant amount of the sun’s radiant heat gets trapped inside the car. This is how heat builds up – the glass forms a semi-permeable barrier which causes some heat rays to be trapped inside the car. Only a subset of all rays – the ones that strike the glass at the correct angle – are able to pass through the glass and get into the car. Once inside the rays bounce around imparting heat with every collision until all their energy is spent, or they’re able to exit the car. Again, only a subset of these rays will strike the glass at the correct angle and be able to pass *out* of the car.

As early as the 1800s it was predicted that CO2 in the atmosphere would do this to the Earth. That has been borne out by experience and is settled science. Scientists don’t question that anymore. It’s a basic principle, like gravity. Without the greenhouse effect to trap heat, the Earth would be as cold as the moon, and we would not be here. (CO2 isn’t the only “greenhouse gas” – methane and water vapor have this effect also.)

While coal use as a fuel began on a very limited scale around 3,000 years ago, it was not mined or used as a fuel on an industrial scale until the invention of the steam engine in 1698. That was the dawn of the Industrial Revolution. Since that time (a period of just over 300 years) billions and billions of tons of coal, and beginning about 1858, billions and billions of barrels of oil have been extracted from the Earth, both primarily for use as fuel. Largely as a result of industrialization, the Earth’s population has multiplied such that there are now 14 times as many people currently alive as there were in 1804 (14 Billion vs 1 Billion). That’s a LOT of burning that did not exist before, and all of the increase coming in an extremely short period in terms of the Earth’s history. Currently we’re extracting about 9 Billion tons of coal and about 33 Million barrels (about 5 Million tons) of crude oil a year. Most of that is being burned.

There is a simple equation for burning hydrocarbons (coal, oil). The reagents are CxHxOx + O2 -> CO2 + H2O. If you plug in the tons of hydrocarbon fuel, you can calculate the tons of resulting CO2. CO2 is a gas at all temperatures experienced on Earth. (Have you ever tried to imagine just a single ton of gas?) Clearly the combustion of tons of fossil fuels every year – with an ever increasing amount, beginning 300 years ago – has released many, many, Millions of *tons* of CO2 into the atmosphere.

Just like water, CO2 has a well established cycle on Earth. Plants take in CO2, use it to form carbohydrate where it stays till they die, and the plant either decomposes or is eaten or burned for fuel, and the CO2 is released to the atmosphere once again.

However coal and crude oil are the product of plants (mostly) that decomposed eons ago and were buried over time. CO2 in that form is said to have been “sequestered” and has not been part of the CO2 cycle – until now. When all that CO2 is reintroduced into the atmosphere by our burning fossil fuels, the only way the CO2 cycle could possibly maintain a constant CO2 concentration in the atmosphere would be if plant life expanded on Earth to the same extent that the CO2 was introduced. Clearly that has not happened over the past 300 years – we know that there has been no sudden increase in vegetation or photosynthetic plankton around the globe in the past 300 years. If anything, with the 14-fold increase in the world’s population, it’s been quite the opposite.

In fact, by various techniques scientists have been able to confirm that the CO2 component of atmospheric air has increased in proportion to the amount of extra CO2 generated by human activity. This in turn is confirmed by temperature measurements taken around the globe over the past few hundred years (using naval log books, for example).

Temperature data show a warming trend over the past 2 centuries – which has accelerated.
CO2 concentration in the atmosphere has increased – at an accelerating rate.
Humans have put many millions of tons of CO2 into the atmosphere over the past 200 years – at an accelerating rate – that had been sequestered for millions of years underground.

If the connections between these facts were not already well established prior to the current century, one would certainly have more than enough reason to investigate whether they were related or not.

The fact is, given a basic understanding of chemistry and physics, the data show what the greenhouse effect – a 19th century discovery – would have predicted, and a phenomenon that climatologists have been warning about for at least 50 years.

The real problem is what to do about it. It would be far better for your grandchildren – and our only home, the Earth – if we moved on and addressed this question rather than debate whether we “believe in” climate change – and humans’ role in it – or not.

Ok – that’s my contribution. If you don’t “believe in” science, then I guess it’s just my opinion. But if you don’t “believe in” the science that supports climate change, then why on Earth would you ever expect anything to happen when you crank your engine or set foot on an airliner? – or leave your car windows open a crack when you park in the sun, or… (fill in the blank)?

You said that,”When I park my car in the sun with the windows closed, it heats up a great deal more than when I leave the windows open. This is an example of the ‘greenhouse effect’ .” So the air in your car is full of the greenhouse gases of oxygen and nitrogen? Perhaps, you farted in the car right before you left.

Do I think man is causing pollution which hurts the environment? Yes. Global warming? No. Why did Michael Mann (one of the godfathers of global warming) sue 2 separate individuals when he was challenged as lying about his hockey stick theory, then refused to supply the documents that supported said theory? Case was thrown out. It is a hoax. Maybe it started with some sincere beliefs, but now too many are making a livelihood from it. Receiving large grants from their countries. There are a number of former ‘believers”, one, the former head of Greenpeace, Patrick Moore, as they now know the data is all skewed by computer modeling.

Would also like to know if 50% of fellow RV’s believe it, why are you still driving an RV? While not quite the same, it is similar, on a different scale, to celebrities/wealthy people who fly in private jets, have huge homes requiring a large carbon footprint, yachts, multiple cars.

The US contributes 4% to the worlds pollution issues and we are constantly working on ways to improve. China & India are the 2 biggest polluters in the world and are doing mostly nothing about it.

Side note. The recent hurricane Dorian had everyone in a tizzy about us having the most Cat 5’s in a short period of time. Of course the info was false. 1932-1935 saw 5 Cat 5’s. Then there is the Amazon fires. Only after the hue and cry do we find out that the picture posted by the celebrities, like Leo DiCaprio, were from pictures 20 years ago. Majority of fires were yearly burns by the farmers in areas other than the Amazon. And the fires in the Amazon are lower this year than in past years. Oh…and the description that the Amazon is the “lungs of the earth”. Another falsehood. It takes in and expels equal amounts of CO2.

Off my soapbox.

Ok, I said this before, but, I will again. 10,000 years ago, the north hemisphere was covered in ice. No humans, but that ice melted, since no humans, what caused that global warming? Humans do uncountable damage to this planet every day, but to assume, we little beings, are causing the temperature to rise is stupid. Let 30 volcanoes (about annual average) all go off at one time, and you wont be worried about warming, you will be wondering where you can get another blanket, and if their is going to be enough food. Significant forces affect this planet, the largest one is the sun, it’s now heading back into the significant cycle of activity for sun spots, and those have a much larger affect on this planet than us humans. Believe what you want, we aint the problem.

Our Earth has gone through 5 mass extinctions, where 80 to 95 per cent of all species in existence at that time were exterminated. And yes, humans were no where around then. Major Continental shifts, massive earthquakes, volcanoes everywhere, asteroids creating massive dust clouds, and more. Most of these took millions of years to evolve, and after that millions more for surviving creatures and plants to adapt to their new emerging environments, creating many very new and different organisms, mammals, fish, birds, plants, etc and finally us humans. All of the underlying causes of our planets past are still at work, slowly but surely, and probably nothing today’s science can do about them. So what can humans and our best science do to help humankind’s future?

We can carefully analyze things we are doing that may be contributing to faster progress on the 6th mass extinction, or more short term just major flooding and catastrophic hurricanes, and what we can do to prepare for that short time, and stop doing things that may be contributing short and long term.

I do believe man is absolutely contributing to current climate changes (and other major pollution activity) over the past few hundred years of our actions. De-forestation for farming and urban growth and continually increasing CO2 emissions creating a heat capturing blanket over the Earth, and more.

How long this can continue before it is irrevocable in its short and long term effects is a matter of debate. Denying it is happening at all is against all logic based on lots of believable science.

Let’s de-politcize this whole debate and really work on gaining scientific consensus on our actions going forward. No action is unacceptable in my mind.

Our air may be thinner than you think. Half of our air is in the troposphere which is only 4 to 12 miles thick. The breathable air is below 5 mi high, the so called “death zone” above which you need to carry oxygen. If you could drive straight up you could do it in 5 min. So.. If you don’t believe we can pollute that after years of dumping stuff into it then you probably don’t believe we can pollute a river enough for it to catch fire, or that if you live next to a freeway you are more likely to have lung problems or down wind of a forest fire you won’t have problems with smoke. You probably think these things are fake news or hoaxes. Some of the chemicals floating in the atmosphere isn’t coming from nature. Those jets flying at 35,000 feet aren’t spewing oxygen and neither are automobiles burning gasoline along with anything else burning stuff. If most of the naysayers had spent most of their career studying and testing this thing then I would be more inclined to believe them, in any case I’m less inclined to believe a politician who won’t be bothered with facts.

Look, enough already. The earth has an uncanny ability to clean itself up. Do you realize the science involved here. I’m sick and tired of the doomsday scenarios.

I’ll write the next hoax for you. We are going into global cooling period. The current ” experts” will then need time to write the script, to explain away their collective BS that has been spewed over the last couple decades , that the earth is burning up. All of you readers who are old enough to remember the ” science” at the time, in the 70ties, the earth is cooling. Its a hoax, there is money in it.

Wake up and follow the money, it’s the biggest scam played on the inhabitants of earth EVER. Want proof, when is the last time you read an article about the travesties India and China are doing to themselves, and the massive pollution of mother earth. Slim to NONE. On the other hand, the United States of America are great stewards of this planet. We learned by our mistakes, but other third world countries could care less from what we learned. Follow the money!

It’s “chicken little” syndrome. The plankton in the oceans create more oxygen than any other source. Research how much money is being made pushing this narrative of global warming. The entire earth is cyclic. Go back 100 years and see what the weather was on any given day.
