What would happen if one of those 2000lb bombs was buried in this berg and exploded?

look at the difference in mean annual temperature between this year and the year in which the temperature observations began...
you'll be surprised at the results

Its gone up. Not sure what was supposed to be surprising about this.

conclusions... the conclusions of information processing can be surprising
. you can see how many degrees it has risen in the time we've been watching
.. planet earth is warming now coming out of another ice age and this is a normal phenomenon that cannot be influenced
can you formulate an understandable definition of what the media calls 'global warming' based on this?

You're a little confused here.
"Ice Age" is when there's ice on the planet .. the planet is in an ice age and has been for a long long time - a bit longer than humans have existed in modern form.
In terms of the glacial cycle the planet was due to begin cooling and enter a period of greater glaciaton than currently existed in, say, the 1880's.
"Was due" but didn't happen is key, and the reason for that is the increase in insulation like a few extra blankets thrown on the bed by human activity - the clearly recorded and well sourced increase in CO2 levels that much has been written about.
If you're looking for detail and definitions then I'd suggest looking through the IPCC report(s) or start with something foundational such as Syukuro Manabe's 1967 classic Thermal Equilibrium of the Atmosphere with a Given Distribution of Relative Humidity

The Quaternary glaciation, also known as the Pleistocene glaciation, is an alternating series of glacial and interglacial periods during the Quaternary period that began 2.58 Ma (million years ago) and is ongoing.

nope
an ice age consists of alternating paired epochs 'glacial - interglacial'
an ice age is when things are bad cold sea level drops and icing occurs
interglacial is the opposite bright warm sea level is high
within these epochs periods of cooling and warming are also distinguished but on a smaller scale
the end of the last glacial epoch began about 20.000 years ago
we are now living in an interglacial epoch that began 11.700 years ago
and one example of a slight cooling in our generally warm times was the Little Ice Age which lasted from the fourteenth to the middle of the nineteenth century
after that global warming began intensified by anthropogenic impact
p.s.
point: saying that 'global warming' is caused by human activity is like saying 'coffee with milk' is just 'milk'

There are several uses of the term "ice age".
> an ice age consists of alternating paired epochs 'glacial - interglacial'
Yes. This is the correct geological time scale usage - a period when there is ice on the earth and a period that often includes glacial cycling - as I said above.
> an ice age is when things are bad cold sea level drops and icing occurs
?? define "bad cold" .. and yes, again an ice age is when there is ice on the earth, whether ice strictly limited to the poles or ice that almost reaches the equator - these are both examples of ice on the earth that occurs during an ice age.
> we are now living in an interglacial epoch that began 11.700 years ago
Yes - and one that was due to end with a greater cooling and more glaciers - this is not what you claimed in your comment above. Instead of this current interglacial period coming to an end it will now be extended with warmer periods caused by the extra insulation added by human activity in the last century.
This is what is called AGW .. that specific component of additional trapped radiant heat energy caused by human added insulation to the atmosphere.
This is readily tracked in various atmospheric fas libraries that have existed since the early Cold War .. and by other proxy means, not to mention looking at the by product of a centuries worth of FF extraction by products or with more recent sat constellations that track gases.
Study more, learn more, work harder to sound less ignorant.
The "Little Ice Age" was more localised to European cells than truly global and it's something bandied about in denier blogs that never truly get into the actual larger picture and global thermodynamics.

Would you care to share your results with the rest of us, instead of making each of us go look?
See, you only have to write your post once. But it's read multiple times. So it's more efficient (and more polite) for the author to do the homework, rather than for the readers to do it.

I'd be more surprised if they measured the same thing.
This is all I can do really because thinking about it with any other feeling than awe or apathy is extremely difficult. We're living in what will surely be a pivotal moment in history, and not all societies have been able to say that.
