You are obviously one of the not too deeply informed either.
Please explain orbital changes? There are "cycles" that ocur over thousands of years but not changes that I'm aware of.... I believe Newton, Galileo, and Copernicus had something to say about that. You are obviously brimming with made up facts about how fast the oceans are heating up. One artical I read said the model need an additional 7 years to get a complete cycle. The models are continuoulsy changed to match the observations. The last I knew, Ice ages are triggered by geography. Of course, it's short sighted to blame this on a single factor. A bit of interesting reading. http://www.pbs.org/wgbh/nova/earth/cause-ice-age.html
There are more than 1100 ACTIVE volcanoes on this planet. All are emitting green house gasses. Mt. Pinatubo all by itself put more green house gasses and other pollutants into the atmosphere in that one day than man did in the previous 100 years. If you turn a blinde eye, the effects are small. There are points in time when trees were growing in the artic regions. No ice caps at all. How did this happen without humans?
The magnetic poles are moving. Is man causing this as well? Does this influence our weather?
NASA thinks we are absorbing an additional .58W /Sq. Meter due to an increase of 300ppM in CO2. The total is only about (something less than 400ppM). So, if we eliminate almost all the CO2 in the atmosphere we now have, we can reduce out energy imbalance by .58W /Sq. Meter. I believe that solar absorbtion ( the energy that hits the ground ) is over 1Kw/Sq. Meter. I suppose it all depends on where you measure it but NASA didn't make that distinction either. NASA is funded by an administration that currently has a green agenda. They also launched a space shuttle against the advice of engineers with intimate knowlege of the effect of freezing temperatures on the SRB's that resulted in the destruction of Challanger. As such you can't tell me they are not politically motivated in their decision making processes.
I have not yet read all your comments but I'm sure I will enjoy them. I could go on and on myself but what's the point?
Please forgive me if I don't jump on the "Humans are killing the planet" bandwagon. I remain skeptical. So do many "Real" scientists.
Wow, WhEEngineer! You finally got one right!! Well close... plants do absorb CO2! This absorption, through photosynthesis creates 'food' in the form of glucose. If it were up to people like you, we would have no more plants, other than ones that burn coal!
You got me, Non-mag...lol, but in my defense, the Harley gets 45 miles/gallon (I drive it to work everyday), and if they made an electric one I would have it (sorry, I'm just not a scooter guy). and my other vehicle, the Prius runs half on batteries. I use a minimum of half the gasoline as the average American, I heat and power my pool from the sun, and am working on a solar array for my house. As soon as it is large enough, an all electric car is next. I am not perfect, but at least I am not sitting idly by and denying common sense stuff. Action is difficult but necessary, all talk and no action is a waste of time. Nothing can be done or undone overnight. The point here is that we (as a society) need to stop fighting the battles for the wealthy, they don't need your help. Fight for yourself and your health, fight for mankind, fight for your children. My point is... Do Something.
I have spent thousands of hours reading papers and books from both sides over the past couple of decades. I have yet to find a single statement denying global warming that was actually true. Every single claim of the Denialists that is not an outright lie turns out to be based upon cherry picked data and dissolves when tested with a complete data set. The best proof is the total lack of non rebutted peer reviewed papers that present significant evidence against global warming.
Desmogblog.com Exposes the liers that lead the denier movement and explores their funding. They have found that 8 of these 16 supposedly expert scientists are paid by the fossil fuel industry to write propaganda.
You will always find some scientists who believe that the world is flat. An increasing percentage ( 90% of general scientists and 97% of climate scientists) have figured out that human caused global warming is real , dangerous to civilization and the economy, and that no viable alternative explanations exist.
And what have we to show for that brief instant of geological time?
Extensive and pervasive slaughter (>15% by Mongol hordes) and genocide (Turks, Jews, Armenians, American Indians, etc); catastrophic diseases like plague and 1917 flu which reduced earth's population by 20 to 40%; two major world wars, one of which incinerated whole cities of people in moments...
So by analogy, since we have been here only a short time, we cannot possibly be responsible for any extensive damage.
I have only read perhaps two dozen "scientific" papers, but they contained only charts of refined data. This is not science, it is simply data collection. And on top of that it seems much of the data was either cherry picked or fraudulant to show the desired results. Quantity does not trump quality and truth is not determined by a majority. Computer models are not science either.
This entire entire global warming thing has taken on all the looks of religeon where true believers will never be swayed.
If you AGW folks want to believe, then so be it. If you want to believe creation happened 10k years ago, then thats OK too. If you think fairy dust can save the planet, well thats OK too. Just do it all on your own dime and do not expect me or my family to pay for it. I'm just not willing to provide a sacrifice for you.
This whole topic should have never appeared in an engineering forum and by the sounds of some of the posts, a lot of non engineers are writing. I have spoken my last word on the subject. I don't have time for tar babies. Have fun
Conservative estimates (of anthropologists) would put man's extent at no more than 2 Million years to present. Dinosaurs quite surpassed humans in their geological history which extends through hundreds of millions of years.
Of course, you can get off the boat wherever you'd like and go with the creationists who place man's existence as contemporaneous with the dinosaurs. That's about the same 'scientific' logic as equating extensive climate alterations due to the exponential effects of only very few degrees of global climate change with the evil machinations of "climate scientists" and the "green empire of world control"!!!
The very simple relation of who actually profits from "climate warming is no big deal" is quite obvious --- ExxonMobil, Cabot O&G, Shell, etc, Halliburton, Schlumberger, and their lapdogs - the WSJ, FOX news, CNN, and most of the MSM. No big deal = Continue to generate income and pad their accounts...
On the other hand, dinosauers are pretty good with frankenfurters.
Aside from the changes in solar activity, which it does increase and decrese, what about the likelyhood that there are other cycles with a much longer period?
For that matter, do you really believe that the world would otherwise just go on the same for ever? Some folks point to evidence showing that at one time we had an ice age, and then things warmed up. Then in the sixties the predictions were for the next ice age. It must have slipped right by me. My point being that the climate change is a lot like the sun setting and the tide rising, in that it is going to happen, and so we need to figure out how to live with it.
I will probably survive, but others here may not. Learn from the dinosauers before it is too late.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
