Dramatic Arctic warming- 30 degrees above average, ice at record low

[h=1]100,000 year ice age cycle linked to orbital periods and sea ice[/h]From BROWN UNIVERSITY Earth’s orbital variations and sea ice synch glacial periods PROVIDENCE, R.I. [Brown University] — Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet’s higher latitudes. For the past million years, these glacial-interglacial cycles have repeated roughly on a…

It's always perplexed me as to what caused the warming and cooling trends thousands and millions of years ago before all the cars, airplanes, etc.

Why, are you under some bizarre impression that only one thing can ever affect climate?

So why is 100% of the warming since 1850 attributed to CO2?

If there are other factors in play then the projections of high warming based on (utterly exagerated) warming since 1979 are out. Thus there is nothing to worry about.

Hmmm....I think it's more likely that you have no credibility, rather than a summary of all the scientific research by scientists worldwide.\

Do you have a problem accepting biology textbooks with Evolution as well?

Various things from changes to the amount of carbon in the environment, changes in the suns energy output, massive volcanic activity, changes in ocean currents, the gulf stream. Among other things as well.

I know the next question will be

Yes they are still influencing the earth's climate, but from scientific analysis, so is human activity something that did not occur in the past

Here's a good interactive summary for lay people on Bloomberg (by NASA scientists) that explains it simply.

Why is it meaningless to ask about how the earth changed millions of years ago and if it was a positive effect?

Lord Tammerlain said:
It is meaningless because there is no context

Positive or negative for who or what? The earth itself meaning the rocks, water and air, in general it does not matter. For the plants and animals, that evolved I am sure some benefited and others suffered. Which is probably one reason we don't see large dinosaurs or wooly mammoths anymore. Climate change was not particularly good for the wooly mammoth

You seem to be confused. Perhaps you should take a break from your favorite conspiracy blogs

Just saw this....in addition to the dramatic Arctic warming and record low ice levels in the Arctic, the Antarctic has followed suit and had a precipitous drop in sea ice coverage- leading both poles to have record low sea ice simultaneously.

We'll see if this trend continues - for now it's a single datapoint for Nov 2016.

You're projecting again. And by the way, there's no such thing as 'physiological projection' as you posted a few hours ago on the main forum :D

Perhaps you need to research what 'physiological' means? Words have meaning.

The phrase you are looking for is psychological projection. It's one of the few things you seem to be an 'expert' at.

But let me guess, you got it wrong on purpose just to 'test' me? ;)

maybe someone here has more time than I do to search a compilation of the RAWS datasets. There are stations in remote areas, that would be untouched by urban and suburban developement. I'll bet the IPCC et al doesn't use these because they don't show the trends they want to see.

Yes- because the IPCC is a giant worldwide conspiracy!

Me?

You're the one who says the IPCC didn't bother to look at/include data because 'it doesn't say what they want'.

That's conspiracy.

It's a bit disturbing that you can't even recognize what you are saying. That's probably because you'd be embarrassed if you thought about it too hard.

That is not a conspiracy. When a group sits down and votes/discusses what to include or not, I don't see that classifying as a conspiracy. They are producing that they are assigned to produce.

I know what I'm saying.

Maybe you can explain this.

The FAR has a very wide range of solar assessments, and even has a small part on the indirect effects. By the time they got to the AR4, the pinned down a small range and low value, based on one of the lowest solar sensitivity studies ever, and the solar values of that years, rather than an 11 year or 22 year average, which would be the only scientific way to be appropriate. No indirect solar effects mentions. That disappeared from their dogma. Come the AR5, and they did the same thing, same study. The 2011 value was not a running average, and lower yet. This was a chosen method to reduce the value of the sun calculated on their table napkins.

I'm sorry you are too faithful to the AGW dogma to see the truths, right in plain sight.

All you are showing is an image from JoNova conspiracy blog. Sadly, like WUWT, she has a history of posting fake stuff.

How about you tell us what volcanoes are active near Larsen C ice-shelf and give a valid source?

Larsen Ice Shelves A and B, by the way, sit astride a chain of volcanic vent islands known as the Seal Nunataks, which may figure into melting and breakups like this and this. (h/t Alan)
In fact, there are a LOT of volcanoes in Antarctica as you can see in this image. Notice that many are near the edge of the ice, and there are none in the interior, which may be a lack of discovery of ancient ice buried volcanoes. Most scientific bases are near the sea, rather than inland, for supply and weather tolerance purposes and there are many places in the interior that have yet to be fully explored.
These images showing known Antarctic volcanoes and satellite measured temperature trends from 1992-2004 below tends to back up the idea that where there is volcanic activity, temperatures have been rising.

Volcanic Map Temperature Trends
Here is a link and excerpt of the story:
The first evidence of a volcanic eruption from beneath Antarctica’s ice sheet has been discovered by members of the British Antarctic Survey.
The volcano on the West Antarctic Ice Sheet began erupting some 2,000 years ago and remains active to this day. Using airborne ice-sounding radar, scientists discovered a layer of ash produced by a ‘subglacial’ volcano. It extends across an area larger than Wales. The volcano is located beneath the West Antarctic ice sheet in the Hudson Mountains at latitude 74.6°South, longitude 97°West.

As for the Larsen C ice shelf...

Only someone ignorant of science would believe it isn't a naturally occurring cyclical event.
