    @Third Baker

    I wasn't suggesting at all that elimination of petroleum use is possible right now. I only used oil companies as a representation of a group directly involved in the increase of CO2 speaking out about the importance of climate change reform.

    Our dependence on petroleum in all the things you listed and more is why reasonable scientists are trying to find solutions now, because the problem will only get worse. Not to mention that petroleum is a finite resource. Energy demands have grown exponentially, which means demands on petroleum have grown which increases CO2 output.

    My point was that debating for or against climate change is a waste of time. There is plenty of data that proves climate change and links human activity to climate change.

    Media outlets and politicians are arguing whether climate change is happening. Scientists are trying to slow or reverse our impact to avoid the potential outcomes.

    "A real scientist would know that scientific accuracy is not determined by who is a superior public speaker in a forum. "
    I'd like to ask you a question: Who below are the real scientists?
    Newton and Leibniz
    Einstein and Lenard
    Dyson and Oppenheimer
    Dawson and Higgs/Rees
    Answer: They're all real scientists who disagreed and debated and sparred over scientific theories. To not allow any debate at all is NOT science!!
    Guess what? Increasing CO2 in the atmosphere allows for increasing temperatures by absorbing infrared radiation. No reasonable scientist disputes this cold, hard fact. But how is this now become "catastrophic?" How has 400ppm CO2 supposedly going to wipe out humankind as we know it? In fact, all computer models rely on POSITIVE FEEDBACK to get to supposedly catastrophic scenarios, of which absolutely NONE have played out thus far. So, another question for you: What is the ratio of cold related deaths to heat related deaths worldwide? The answer will be SHOCKING for you Schnee. And this is EXACTLY why I will never be able to publicly debate any alarmist who loves to throw out Milankovitch cycles to impress people into believing them.

    @conservative scientist: "Every time we have a hot day or a series of hot days, then it's proof of global warming. . . , but cold days or a series of cold days are more proof of global warming."

    No, silly. Hot days are climate. Cold days are weather. Try to keep the narrative straight.

    Here is a simple calculation I would like people to perform. Take a standard cubic meter of nitrogen gas (good approximation for the atmosphere), and assume it has the standard Boltzmann distribution. Calculate the average velocity of each particle, multiply by half the weight, and there you have the average kinetic energy, also known as temperature.

    Now, take 1 millionth of the particles (1 part per million) and speed them up to 90% the speed of light. Now, recalculate the average kinetic energy (also known as average temperature).

    How much does it change the temperature? The answer - not much at all. This is clearly a worst case scenario as "global warming" will note heat particles up to relativistic speeds. The conclusion: parts-per-million changes in CO2 concentration are not going to change the overall temperature in a measurable way. Do the math yourself.

    Schnee:

    "paleoclimate evidence that suggests a 100+ thousand year Milankovitch cycle brings CO2 from around 180 to 300 and back down again"

    And how exactly is this "paleoclimate evidence" currently causing "catastrophic" changes right now? How many more people are dying because of this? How many civilizations are being wiped out? Schnee, how do you define "catastrophe"? Careful, because nobody else from the alarmist side seems to know exactly what that means.

    The one third increase can easily be explained by the lack of forestry, and population increases. In just the US we tripled our population from 1920-2010 from 100 million to 300 million.

    Studies done eliminating volcanic activity have shown that there is no global warming.

    "There's not one shred of evidence in the past, or now, that humans have any appreciable let alone catastrophic effect on climate. "

    That is just demonstrably false. The second most important greenhouse gas in the atmosphere increased in concentration by a third in less than a century defying all paleoclimate evidence that suggests a 100+ thousand year Milankovitch cycle brings CO2 from around 180 to 300 and back down again. We went from 300 to 400, with carbon isotopic analysis in the atmosphere pointing towards humans. In the meantime global temperatures have risen over the past century and all alternative explanations do not explain that at all. If it were the sun we'd have peaked in global temperature a few decades ago. The 5 warmest years in the modern record were the 5 most recent years despite being in the weakest solar cycle in almost a century.

    "Why no debate?"

    A real scientist would know that scientific accuracy is not determined by who is a superior public speaker in a forum. Obama and Romney split the debates, that didn't mean who was speaking truth or the better president switched from day to day.

    The climate is always changing and will continue to change no matter how many tax dollars we waste on it . There is no proven program that will guarantee you can change the Temperature 1 Degree plus or minus over time by pouring millions of taxpayer dollars on scientific theories that use suspect models to draw absolute conclusions. They can make their studies come out the way the people who are footing the bill wants it be.

    After spending the past 14 years researching climate change, I'm tired of fighting against the brick wall of the climate machine. If you repeat something enough times with enough money, it becomes "true". It's truly a phenomenon. There's not one shred of evidence in the past, or now, that humans have any appreciable let alone catastrophic effect on climate. Set aside the temptation to rely on opinions, organizational statements, and personalities and look at the facts. You can call me a "denier", and "goof" or a "charlatan" all you want. But facts are facts, despite any spin. Spend some time. I've spent over 14 years. Do you think this is why nobody has ever agree to a public debate based on current outcome studies (and not computer generated models)? Why no debate? Because the current findings are humiliating to climate alarmists. And I mean HUMILIATING. I especially love the outcome studies on death due to extreme heat vs. extreme cold, or the supposed malaria pandemic, just to name a couple.

    We had two ice ages in the middle ages, separated by a period of global warming. Our climate is always changing, remember Northern Utah was once a great Lake.

    Without dinosaurs, mankind would still be in the middle ages. We should praise fossil fuels, and have a national Dinosaur day to thank them for the Industrial revolution.

    hokieland43: Science or no science, the real issue here is that the human race is not going to give up fossil fuels and live in caves because we can't, it’s simply not possible! People will never give up affordable food, medicines, clothing and shelter (especially when these kinds of arctic blasts happen), all dependent upon fossil fuels! That isn't going to happen! In the meantime, I suggest you give your teaching skills a test and go to the mid-west and teach those people that global warming is real!

    @Mainly Me

    "Tens of thousands" of scientists huh? The sources I suggested people look at are not news sources, they are scientific organizations showing data. If you dig deeper, they will also explain how the data were collected and where they were collected.

    I teach freshman level geoscience courses at a university and work with many scientist from different fields. I haven't found any reputable scientific sources disproving climate change. I have never met one scientist who thinks climate change is fake.

    Give at least 1 scientifically backed source of data disproving climate change before you claim "tens of thousands" of scientist have disproved it.

    Energy companies receive no financial benefit for publically stating climate change is a real problem. Why would they support scientist about climate change when the products they sell are one of the leading causes of the issues?

    Some people think that the earths complicated climate is like a refrigerator box, and north is equal to higher altitude.

    Some people claim 10's of thousands of accredited scientist don't believe in Global warming, but don't provide anything but their comment as evidence?

    "Global warming is causing temperatures of forty below zero?"

    Global warming appears to be making a meandering jet stream more common. That in turns makes more frequent polar vortex breakup, which involves both Arctic air reaching far south and warm air reaching far north. This particular type of event may occur more often with global warming but because the Earth is warming cold records are being set less often, and warm records more often.

    The phrase 'global warming' is only part of climate change. The push made by scientist is to reduce release of carbon dioxide and other gases to reduce climate change. This includes increases in extreme temperatures (like we are seeing on the cold side) as well as increases in extreme weather (multiple massive hurricanes in the past few years) and drought conditions, which Utahns should care about very much and other concerns. Global warming is only a part of it. The heart of what scientists are saying in this article is that climate change concerns are based on trends. The trend of average and extreme temperatures is increasing, and coincides with the increase of carbon dioxide in the atmosphere. You can find these trends on NOAAs and NASAs websites pretty easily. Just type 'CO2 trends NOAA' and 'average temperature trends NASA' into google.

    The fact is that data and science proving climate change is common and from reputable sources. Climate change isn't being debated anymore in the scientific community.

    A side note: Many large energy companies, ie. Exxon and Chevron, all agree climate change is a concern that needs to be addressed.

    This is how the deniers deal with evidence, they counter with anecdotal observations instead of the bigger picture, and research presented by a small percentage of fringe pseudo science blogs, much like the revival of the flat earther's.

    "If I'm reading it correctly people are assuming that global warming is responsible for the current deep freeze?"

    A slower, more meandering jet stream makes excursions of polar air down south more common. There is research suggesting that global warming (particularly in the Arctic with the sea ice melt) is leading to a slower jet stream. So it's not saying we haven't had these before, just that these are likely to become more frequent. But at the same time we are still setting cold records less frequently than we normally would expect if there were no global warming at all and global temperatures this week are still above average.

    "Warm air is lighter than cold air and will not push colder arctic air south. Look at the open freezers and refrigerators in a grocery store with open tops."

    The comparison to that freezer with an open top is the stable layers experienced in the Salt Lake Valley during a wintertime inversion. So that's a good analogy for explaining why the pollution gets trapped in the valley.

    But... up-down is not the same as north-south. The refrigerator in your house is going to have temperature problems if you leave the forward facing door open.

    Thanks to the breakup of the polar vortex caused by a sudden stratospheric warming event a few weeks ago, the cold air is down here (well, here being the midwest, Europe, and Siberia), the Arctic has large areas much warmer than average, and the Earth is still globally warmer than average this week.

    Oh my. Science teacher, huh? This isn't about lighter or heavier. It's about pressure and currents. Ever notice that those freezers have walls around them? Ever wonder why? It's to keep the pressure and currents from pushing the surrounding cold out. Just like what's happening with the Arctic. But, hey, don't let facts get in the way of your "knowledge".
