How Global Warming Really Works

Is there any way to infer past temperatures from ice-strata?

Yes and it totally destroys strange and trysails arguments. Hence why they don't like to them.

 

[thør]

No Antarctic data before the 1970's.

What does it look like since the late 1970's? That's when high quality satellite data became available.

Not after it melts.

In summary, ice cores contribute important records of past greenhouse gas concentrations on time scales ranging from a million years to several decades. The general lesson drawn from these records is that, as predicted by simple radiation balance models, adding greenhouse gases to the atmosphere leads to warming of the planet. Human additions to greenhouse gases are very large compared to natural variations, therefore anthropogenically induced global climate change is a simple expectation as opposed to a surprise, and thus not a matter of serious debate.

I like all these trolly anti-science amateur climatologists blinding reading whatever bullshit Exxon paid to get published.

I never disputed that the temperature and the CO2 level have fluctuated and will continue to do so in the future, nor do I doubt that humanity has an impact on the environment. I mean, duh - there are billions of us.

But I just don't see it as a big deal. Some animals will do better and some will do worse, some will deal by migrating and some will go the way of the dodo. The only constant in the world is change.

I have found that all of the most unbiased climate change data is gleaned from Literotica.

That attitude reflects a very strangely studied indifference to the fate of (I presume) your own species.

Yes, that is exactly correct, except that you are confusing "all of the most unbiased climate change data" with "porn," which is, I grant you, a very common mistake. And not on this board alone.

Oops. My bad (as the kids say).

Is that what the kid are calling it now?

There must be some kid somewhere

There must be some kid somewhere

Of course there is, or was, I'm wearing its skin as gloves!

It's nice to have a comfortable pair of gloves.

I don't believe that the fate of my species will follow the path that hysterics and alarmists are imagining. You know, the kind of people who get their panties in a bunch upon realizing that the Earth isn't an airconditioned studio apartment on Manhattan, but a living environment with climate variations on a geological scale.

Another group of similar hysterics and doomsday prophets were wrong about the 2012 apocalypse too, remember?

I don't dispute that our climate is changing constantly - I would actually be more worried if it didn't, because that would be a first in our planets history - but I don't agree with Hollywood and the agenda-driven parts of the science world that that's all of a sudden a bad thing. I'm sure that barking with the flock is a good way of securing grants and tenures for these people, and I don't blame them for selling out. I'm just not buying....

A scientist spreading pseudo-science can't be any more mixed-up than a flock of barking seagulls...

In 2011, the clerical intellects in Egypt proposed that the pyramids be destroyed because they were idolatrous reminders of Egypt’s pre-Islamic past. Egypt’s real problem is more prosaic -- the mismatch between an agricultural system that can feed 40 million and a population of 84 million. Egypt had been a grain exporter for thousands of years. It is estimated to have had a population of 4 million at the time Napoleon Bonaparte visited its shores in 1798. By 1960, the population had risen to 28 million and they were importing one million tons per year of wheat. Grain imports, wheat and corn, are now running at 15 million tons per year.

With a population growth rate estimated at 1.8 percent per year, another 1.5 million Egyptians are created every year. On a spare, almost completely vegetarian diet of 350 kg per year of grain, each year’s cohort of new Egyptians will require over half a million metric tons of grain as adults. Thus Egypt’s grain requirement ratchets up by half a million metric tons every year. Egypt’s ability to grow grain has peaked, limited by the available water from the Nile. The switch from high-water-consumption crops such as rice and cotton to wheat has already taken place. On the current trajectory of rising demand, the import requirement will be 28 million metric tons of grain by 2030.

The situation may very well be worse than that. There has been a population explosion in the last three years after the Arab Spring. Between 2006 and 2012 there was a 40% increase in the number of births in Egypt, with births in 2012 560,000 higher than in 2010.

What holds Egyptian society together for the moment is subsidized bread. Three-quarters of the population have ration cards that entitle the holders to subsidized bread, sugar, cooking oil, propane, and gasoline. The total food subsidy system costs about $4.4 billion per year. With the bulk of the population’s calories provided by subsidized bread from effectively communal bakeries, there is almost no resilience in the food supply system in Egypt. If the imports or the subsidies stop, Egyptians will starve.

Whatever his failings as a fair and just ruler, Hosni Mubarak, the former president of Egypt, ran the country as an ongoing concern. By late 2010 the country’s foreign exchange reserves had risen to $35 billion. Following his resignation, Egypt’s foreign exchange reserves began to fall at the rate of $2 billion per month. By early 2013, they had fallen to $13 billion. President Morsi was overthrown in a military coup not so much because he is an Islamist but because Egypt’s only potential savior, Saudi Arabia, would not contribute to Egypt’s treasury while the Muslim Brotherhood was in charge. The Saudis duly tipped in $5 billion within a fortnight of Morsi’s overthrow.

Even the Sun is ganging up on Egypt. NASA researchers have found some clear links between solar activity and Nile River levels. The Nile water levels and aurora records tracking solar radiation have two somewhat regularly occurring variations in common -- one with a period of about eighty-eight years, known as the Gleissberg cycle, and the second with a period of about two hundred years, called the de Vries cycle. Solar activity is now declining to levels last seen in the 17th century. That decline will result in drought in East Africa at the headwaters of the Nile.

The alarmists have never understood, or at least refuse to acknowledge, the linkage between food production and temperature. Higher temps equal more food, lower temps equal less.

Global Warming, this is how it really works..... nobody knows, it's all educated guesswork at best. The chances are better that a man made disaster or aliens invading us will wipe out humanity before the climate does.

That doesn't mean we shouldn't seek cleaner energy ,recycle or not pollute the water & air.

Radical left POV & Radical right POV will solve nothing.

Oh let's not forget that big ass ball of burning hydrogen up in the sky while were at it.

The upper panel shows the air temperature at the summit of the Greenland Ice Sheet, reconstructed by Alley (2000) from GISP2 ice core data. The time scale shows years before modern time. The rapid temperature rise to the left indicate the final part of the even more pronounced temperature increase following the last ice age. The temperature scale at the right hand side of the upper panel suggests a very approximate comparison with the global average temperature (see comment below). The GISP2 record ends around 1855, and the two graphs therefore ends here. There has since been an temperature increase to about the same level as during the Medieval Warm Period and to about 395 ppm for CO2. The small reddish bar in the lower right indicate the extension of the longest global temperature record (since 1850), based on meteorological observations (HadCRUT3). The lower panel shows the past atmospheric CO2 content, as found from the EPICA Dome C Ice Core in the Antarctic (Monnin et al. 2004). The Dome C atmospheric CO2 record ends in the year 1777.

While that's not true strictly speaking I don't think anybody has ever really discussed this one way or the other.

Actually I've written about it quite a bit. But that was sometime ago and I don't feel like repeating myself.
