Is this graph bullshit?

I don't mean to make this into another climate change thread, I just actually found one of these graphs with a Y axis and got excited. I want to hear how this is wrong, because though I want it to be true I have a gut feeling

Probably, but it's that missing century and a half that we're concerned with.

Well then couldn't we supplement recent data of how warmer we are now to then? Because there is where most graphs are set, it seems this one is just trying to say that this may not be anthropocentric by insinuating the warming now isn't more rapid and hot then it has been in recent memory.

Is there any way in hell someone could post another graph so we can put together all the data?

To make sure that there are no political interests, no special interest groups involvement, and no single scientists bullshit pet theory they're trying to push without evidence we put together a team of scientists from all around the world.

This team, called the Intergovernmental Panel for Climate Change put together hundreds of pages of data. All available to anyone for free.

Every answer to every question you could ever have has been freely available for years. Stop going to uneducated blog sites using bad data to push an agenda.

Oh I'm not looking to push an agenda I just found this off some random asshole, and this one actually has a Y axis which put it above other graphs I've seen posted.

Also you damn know well that even when you go through those steps people and their projects are incredibly suitable to corruption and perversion. In fact the fact it was so big already makes it potentially more corrupt than just some random study

How? This is from an ice core and no one has been recording the temperature on that glacier even in the modern period.

The bigger issue is that this graph does not show global temperature, it shows local temperature from one place in Greenland. Pic related is global temperature over the long term.

Wrong, it only takes one whistleblower. Also the IPCC doesn't do its own studies, it simply compiles and summarizes the data that has already been published.

Earth scientist here. We actually have very good proxy data for temperature. Let me explain 1 simple one.

The ice cap over the arctic prevents soil blown from the continents to easily reach the ocean floor. Any soil found beneath the ice cap is extremely fine. If you take drill cores around the edges of the arctic ice cap you can tell, over extremely long periods of time, how the ice cap has changed in size. We know how far it reaches today, we know how warm it is today, we just project that data into the past.

Simple. Temperature going back hundreds of thousands to millions of years in the past.

I didn't say that we don't have proxy data, I said we don't have instrumental data for the GISP2 site.

Ice core scientist here, yes we do. GISP2 site has now become Summit Greenland station. https://en.wikipedia.org/wiki/Summit_Camp
>Summit Station was originally established in April 1989 in support of the Greenland Ice Sheet Project Two (GISP2) deep ice coring effort. A ski-equipped C-130 from the New York Air National Guard performed an open snow landing near the site, bringing the put-in team consisting of Mark Twickler, Jay Klink, Michael Morrison, and two navigation specialists. They located the exact location chosen for the GISP2 drilling site, established a camp, and laid out the runway. Subsequent flights brought in additional materials and personnel needed to build the station. Two major structures were planned and built: The Big House, an insulated panel building (housing a galley, common space, and office), elevated to minimize snow drifts; and a geodesic drill dome to house the deep drill. Extensive under-snow trenches were also constructed to house the core handling, processing, and storage facilities. Many smaller Weatherport hut buildings and tents were also erected as storage and shop areas, as well as sleeping quarters. These were erected and taken down each season. On July 1, 1993, the bedrock was reached. Originally a summer station only, the station had been manned year round since the early 2000s, with a winter population of 4 to 5.

Problem is that we don't have any data before 1989. These days you can look up Summit station temperature in real time

That graph is outdated because it was based on GISP2 borehole temperature reconstruction. There are plenty ice cores drilled afterward and more sophisticated analysis beyond borehole temperature inversion, for example (pic related)
https://www.nature.com/articles/nature08355

In all they say the same story that Greenland was WARMER 10000 years ago, and the ice sheet was thinner. Greenland was warmer because 10000 years ago coincide with Holocene solar maxima, and the high latitude regions are the most affected by changes in solar radiation due to enhanced albedo feedback, among many others.

This does not disprove anthropogenic climate change however, as the mechanism was completely different. We are no longer in solar maxima, but still have comparable temperature as if we are in solar maxima
