Global Warming & Climate Change Discussion

Status
Not open for further replies.
We surveyed the biophysical science faculty of the Big Ten universities in the US to ascertain (1) their beliefs about climate change, (2) their beliefs about climate science, (3) where they get their scientific information, and (4) their cultural and political values.
That population is overwhelmingly liberal ergo expected to respond favorably to "climate change" regardless of their research/credentials.

Figure 1 is interesting though on that link. Natural resource professors are more skeptical than the rest but when it comes to "human-caused temperature rise," engineers are overwhelmingly skeptical. Sure, 85% of the surveyed engineers still say humans caused rise in temperature but you can clearly why this topic is political: engineers are far more likely to be conservative than liberal. The survey reflects that.

That is actually really really bad news. Large "blobs" of water that are no longer being properly conveyed throughout the ocean.
That's not what they're speculating in the article. The best hypothesis now is that it's from the glacieral meltwater from Greenland failing to mix with the salt water of the ocean. Nothing is certain at this point though.

Did you not know or understand
There is no global warming ( There is Climate Change as Always ).
that will come when the Sun runs out of hydrogen to burn and then starts on its helium
That's the start of the Suns old age when it turns into a red Giant
As the Sun expands it turns into a red Giant (it will start to heat up the earth) till it is big enough to adsorb the earth

Until the Sun Expands the earth is like a poker pulled from a fire " Slowly cooling"

i do understand that. so it wasn't aliens then? darn.
 
To many ( Smart and not so smart ) people confuse Global warming with Climate change.

Global warming is when Planet Earth Gets Warmer ( that means a external heat source that heats the planet more than the planet loses ie a net gain in heat)
Earth formed as a coelessing ball of gas and other debris
from liqued rock it has cooled to form a skin which we live on for it to get warmer an external heat source must act on it like a expanding red giant sun

for comparison take a red hot poker from a forge
pull it out and watch it cool the only way to cause it to warm is to supply another energy source such as moving a heat source nearer such as dragging the forge to the poker or high energy infra red heat source

that poker is planet earth IT is Slowly Cooling and will continue to cool until the sun expands and heats it up

Climate Change is the poker removed from the fire and blown on by drafts sure you can get it to glow and raise the surface temp from changing the surounding atmosphere but its still overall cooling .

People need to stop confusing Global warming with Climate change
 
Who is confusing what now?
 
Who is confusing what now?

Mankind waits for sun to expand ....then we will have Global warming
its so simple
Climate change on the other hand is not so simple or easily solved

yes, but who is confusing the two?
 
It all starts with the thread title Post
start with the poll
Do you think that the "global warming" crisis is a massive scandal?
29 pages later and over 700 posts with the majority then talking about Climate Change

Climate Change is NOT Global warming

and? does this mean aliens could be responsible for climate change? please say yes.
 
its 29 pages and 700+ posts aurguing about climate change not global warming

The planet is cooling down till the sun expands parts of the surface are experiencing CLIMATE CHANGE always has and always will until its enveloped by the sun

in the end Its a pointless (thread)

i said
Earth as a Lump of metallic rock is cooling HAS BEEN SINCE IT FORMED
it will only get hotter as a result of our local star turning into a RED GIANT

by the time that happens who the f**k is going to be around to worry about that

i ain't changed my opinion

and? does this mean aliens could be responsible for climate change? please say yes.
I know what your doing and you have my SUPPORT
your trying to get the thread bounced to GN :)

The last time atmospheric CO2 exceeded 400ppm was 5 million years ago. It was approximately 290 ppm in 1870. We're at just shy of 400 ppm as of August.

Unfortunately it appears you don't know about the life cycle of our sun. The sun is actually brighter now than it was a billion years ago, and it will be even brighter in the future. The earth will be on an extremely long term general warming trend, not a cooling one.

http://faculty.wcas.northwestern.edu/~infocom/The Website/evolution.html

"Since its birth 4.5 billion years ago, the Sun's luminosity has very gently increased by about 30%.3 This is an inevitable evolution which comes about because, as the billions of years roll by, the Sun is burning up the hydrogen in its core. The helium "ashes" left behind are denser than hydrogen, so the hydrogen/helium mix in the Sun's core is very slowly becoming denser, thus raising the pressure. This causes the nuclear reactions to run a little hotter. The Sun brightens."

Thank you for what I assume will be a changing of your opinion given this new information you have learned.
 
your post just adds to the crap in this thread
you assume and presume to much

You're telling the guy who's posting verifiable, cited facts that's *he's* posting crap, while your posts consist of nothing but poorly-worded assertions that "global warming doesn't exist" and "climate change is the cooling of the planet". I suggest you refer to a dictionary for the definition of the word "change".

Never said that
What i said was

your post just adds to the crap in this thread

There is a lot of Crap in this thread
again i re-iterate
just adds to the crap in this thread and to re-emphasis i never said
magibeg was posting crap

Just that he was adding to the Crap already posted
 
So 5 million years ago aliens caused climate change/ global warming?
I've been trying to find theories about what caused CO2 to rise/fall during the Pliocene period and I'm coming up blank. You're guess is as good as mine.

It was aliens. You see, since the industrial revolution aliens have been repopulating Earth and their repopulation is causing CO2 levels to rise. If we can find and exterminate the alien scum we will have solved the global warming/climate change crisis!

You're at the point now where paywalls for scholarly papers will become a problem as well as finding the specific experts who focus on those areas. I'm hesitant to give information because i'm not confident enough in it, but there has been times throughout history where sharp rises and falls of CO2 have coincided with algae blooms in the oceans. (There are so many more factors to this so please take it as one of many contexts)

Large geological events such as caldera's also have large effects, not just directly but indirectly. Anytime there is a large extinction event. At one point the formation of trees locking away carbon before bacteria could release it caused a severe drop in CO2 levels.

This is a very deep rabbit hole.

If you're going to live and die by terminology, then the title of the thread is:
The fiddling with temperature data is the biggest science scandal ever

The thread originally asks whether the alteration of temperatures, recorded at particular locations, being altered to normalize results to a theoretical model is important. That theoretical model has created allowances for increased average temperatures, and the harvested data did not support said theoretical model. Scientists chalked up said discrepancies as problematic, and to normalize data to their conclusions they altered temperature data to account for "imprecision" in the instrumentation. In the scientific world, that should get you crucified. You create a model, falsify data to match the model, and in the process justify a lie with data. That is unacceptable.

People have run with said banner, and taken it to both sides of the climate change debate. Deniers say this is a situation where all data should be thrown out, because of lies by some. Supporters say the significance of the data is negligible, given the weight of the other data. Reasonable moderates condemn the lie, and ask whether we actually have enough data to model anything.


On a separate note.

Citing surveys, like Magibeg did, is not bringing facts to the table. If you surveyed the average Saudi citizen they'd believe in Allah, the average resident of the US believes in the Bible, and the average resident of Lancaster PA would still use a horse as their common means of travel. Surveys, by their nature, aren't a way to gather facts. Facts exist outside the realm of opinion, and opinions are what surveys gather.

So 5 million years ago aliens caused climate change/ global warming?

The Pliocene ended with a rather spectacular number of different thing going on at once. Water from the ice caps began to cool the oceans. The Albedo of the planet decreased on average. The oceanic heat conveyor started up, which today delivers equitorially heated water northward and colder waters southward. We experienced a massive extinction event, due to a supernova ionizing our atmospere and functionally removing the ozone layer. All of these events, on a geologic time frame, occurred in rapid succession. What one event caused CO2 levels to decline may be impossible to tell, or more importantly it may have been a series of events.

As far as global warming occurring then, not as far as I can discern. The relatively large amount of evaporation of water, into a greenhouse gas (yeah, people often forget water vapor is a greenhouse gas) may have actually been a huge factor here. Our current oceanic heat conveyor didn't move warm waters north, so the equator baked in more intense heat. The CO2 level may have been a factor of so very many living things, but that's largely conjecture. Scientist, to my understanding, have yet to explain how much CO2 would occur naturally as metabolic byproducts before it was locked away during the extinction events which give us our current rich hydrocarbon deposits.

In short, my understanding is the Pliocene was less global warming, and more a renaissance for organic chemistry. I could be wrong, but it seems like there's no way to get a definitive answer on that particular point.

This graph shows how the average surface temperature of the world’s oceans has changed since 1880. This graph uses the 1971 to 2000 average as a baseline for depicting change. Choosing a different baseline period would not change the shape of the data over time. The shaded band shows the range of uncertainty in the data, based on the number of measurements collected and the precision of the methods used.

Data source: NOAA, 2015 5


I'm sure it's been said already but i can't read posts in this thread - it infuriates me.

Even if it's not getting as hot as predicted - the oceans are.
