Author | Topic: Global Cooling? | |||||||||||||||||||||||
BMG Member (Idle past 239 days) Posts: 357 From: Southwestern U.S. Joined: |
Someone posted this article I have below as support that the global warming phenomenon is a "hoax", and that the Earth is likely going to cool.
http://ibdeditorial.com/IBDArticles.aspx?id=287279412587175 I have yet to refute this argument. I am researching now the sources that are used in the article, and the effects of the solar cycle on the Earth's climate, but I could use the help of the EVC team. Here are some quotes from the article itself: "[Kenneth] Tapping reports no change in the sun's magnetic field so far this cycle and warns that if the sun remains quiet for another year or two, it may indicate a repeat of that period of drastic cooling of the Earth, bringing massive snowfall and severe weather to the Northern Hemisphere". And one more, from the Hoover Institution, "The effects of solar activity and volcanoes are impossible to miss. Temperatures fluctuated exactly as expected, and the pattern was so clear that, statistically, the odds of the correlation existing by chance were one in 100," according to Hoover fellow Bruce Berkowitz. " One more, from the Hoover Institution, "The study says that 'try as we might, we simply could not find any relationship between industrial activity, energy consumption and changes in global temperatures'".

I was wondering last year with the lack of massive hurricanes in America and with all the snow I'm having to shovel this year if in fact it was due to low solar activity.
It's interesting to see the world appearing to be cooling off lately in spite of the wacko environmentalists that say its heating up due to global warming gases and not the sun solar activities. Its just like your furnace you turn the dial up and it warms up turn it down and it cools. P.S. I'm running out of space to put the snow piling up, some friends I know are keeping their thermostat at 40 degree's F. They just hang out elsewhere until bedtime then keep warm with an electric blanket, etc...

Thanks for demonstrating the most common misconception about global warming from the ignorant side of the spectrum. Here's another look at the ignorant side of the spectrum!!!!!!! ----------------------------------------------------------- 15. Incredible. Will somebody show me a statistical analysis showing CO2 changes leading temperature changes in the paleorecord? If CO2 has a forcing effect beyond background noise, there should be *some* positive mathematical correlation. The fact there is nothing showing that CO2 changes actually caused temperature changes should be paramount in this discussion, as it pertains to reality. The fact there is *no correlation* yet the Supreme Court just made it easier for politicos to control carbon, therefore life, is scary. Grist.org: Climate. Justice. Solutions. | Grist

I understand that sunspots are essentially "loops of tangled magnetic field" rising through the surface, and that these areas burn slightly cooler than the rest of the Sun's photosphere - roughly 1500k cooler - but I am at a loss regarding the connection between sunspot activity and the Sun's intensity.
Where is the affiliation? I like the low tide analogy, and I enjoyed your post. Thank you for your time. Lastly, my source concerning the sunspots was "Horizons: Exploring the Universe", by Michael A. Seeds. I have to learn how to use footnotes. P.S. There is a great documentary on the History Channel called "The Little Ice Age", referring to the Maunder Minimum, between 1610 and 1745, I believe.

I find it interesting the scientists in the field are screaming to the flat earthers (Gore and company, etc....)that the earth is round that were not the cause of global warming, but no one listens to the experts these days, etc...
P.S. You must remember Gore is not a scientists, the media was wrong in the 1980's they were screaming global cooling was caused by fossil fuel not listening to the scientists then and the media are wrong today screaming global warming is caused by fossil fuel. I guess if we made diesel and gasoline from coal that would make energy cheap green up the earth, but it won't happen not because of science but because of politics, unless congress intervenes in America these wacko flat earthers (Hiliary or Obama if elected) will start taxing that which powers your car, heats your home, and say the lie that your doing your part to stop global warming, etc.... Heaven help us if they would sign that perverted kyoto treaty and use the EPA to enforce this ungodly tax, etc... ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ What would happen if tomorrow we were told that, after all, the Earth is flat? It would probably be the most important piece of news in the media and would generate a lot of debate. So why is it that when scientists who have studied the Global Warming phenomenon for years say that humans are not the cause nobody listens? Why does no one acknowledge that the Emperor has no clothes on? http://www.canadafreepress.com/2007/global-warming020507.htm

- but I am at a loss regarding the connection between sunspot activity and the Sun's intensity. I'm not sure the scientists know either, they just have reams of data on the correlation. It may be something as simple as solar energy being tied up in the magnetic fields is not free to radiate away from the sun, or that it results in changes to the energy levels (radio wave interference also associated with sunspot activity) and thus the spectrum of what is radiated.
I have to learn how to use footnotes. I don't think we have a mechanism for that, so you have to use html tags - footnote(1) becomes footnote(1) Then at the bottom you can do:(1) - footnote text and it becomes(1) - footnote text Enjoy.

"[Kenneth] Tapping reports no change in the sun's magnetic field so far this cycle and warns that if the sun remains quiet for another year or two, it may indicate a repeat of that period of drastic cooling of the Earth, bringing massive snowfall and severe weather to the Northern Hemisphere". It is now 1:00 a.m. in my state and we have had several hours of darkness (sometimes referred to as night.) This has resulted in noticeable cooling of our state. If this darkness continues for another 83 hours, the cooling effect will completely reverse the global warming we had previously experienced. If this darkness continues for another three weeks, our climate will be like Montana's winters..

Another issue is that the weather in the Northern Hemisphere is kept artificially warm by the Gulf Stream, and that significant change or disruption of this system would cause colder weather -- without any regard to global temperature levels.
This looks like a couple of straw dogs harnessed together to obfuscate and avoid the real issue. IF global warming is occurring (consensus is yes) then should we do something about it, or should we find excuses to keep our heads in the sand? Are we ready to start conscious control of the climate/weather?

Yes, the Thermohaline Circulation, if disrupted, will cause a severe temperature fluctuation of Western Europe. The Greenland Icesheet, especially, if it continues to melt, will dump millions of cubic liters into the Atlantic, severely disrupting the circulation of heat from the Equator to the N. Hemishere. Europe's Mediterranean climate will be no more. Crops will wither, tourism will slow, and Europe, in general, will be hurting.Thermohaline circulation - Wikipedia

johnfolton writes: Incredible. Will somebody show me a statistical analysis showing CO2 changes leading temperature changes in the paleorecord? I don't understand your point. Was there ever a source of CO2 being pumped into the atmosphere in the past like there is now? If not then there is no direct way to have global scale evidence one way or another. Unless you have a time machine handy, you are making an impossible demand. We do know from physics/chemistry that CO2 is one of the gasses that reflects the IR light the earth radiates to cool itself. I'm no expert, but obviously this is expected to cool the earth and most computer simulations agree that this effect explains most of the warming we have seen.

Sunspots do tend to be correlated to the sun’s energy output which could directly change the earth's temperature, but there is another way they could have an effect. Sunspots happen more when the sun's magnetic field is strong and this magnetic field tends to drive away the electrically charged cosmic rays that bombard our atmosphere. These cosmic rays produce ions in our atmosphere that could in theory precipitate cloud formation, which could have a net cooling effect depending on the cloud's height and density. This is a favorite argument of some global warming skeptics: the sunspots drive away cosmic rays which reduce cloud formation. There are just two problems with this.
a) I don't think there is any evidence of cosmic rays increasing cloud density. They form clouds in cloud chambers because before the cosmic rays pass through there is nothing for condensation to stick to. The atmosphere, on the other hand, has plenty of dust in it already that clouds can form around. Cosmic rays may not help. b) We can measure both the rate of sunspots and of cosmic rays. Both follow the solar cycles as one would expect, but there is no trend consistent with our observed warming over the last 30 years. Here is a crappy plot showing this from the University of Chicago Climax neutron monitor. It shows the rate of incidence of neutrons produced from cosmic rays overlaid with sunspot #s: Based on this evidence, I see no reason to link sunspots or cosmic rays in any way to the warming that has been observed recently. Maybe they are indicative of future sun behavior that could be relevant. But you're better off looking at the actual flux of solar energy reaching us on the earth if you're trying to understand how the sun could have influenced the current climate.

True, the sun has a slightly higher activity now than it did 150 years ago. Razd has already given you some solar data, but here is one showing a larger time scale from wikipedia. Based on this plot, showing solar energy output during the recent period of warming, I don't see any reason to think the sun is the cause. Do you? Edited by fgarb, : Shrinking the image
