"This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements"
Hi, so we mixed multiple ways of measuring something in the same graphic w/o giving the references of the paper telling why we can and in what conditions. I like that, it smells so much of political smoke and mirrors.

See level rise
It's not the rise which is important but if it going faster or slower. And let's just check a 2011 study instead of a 2005 one.

Abstract:
Quote:
HOUSTON, J.R. and DEAN, R.G., 2011. Sea- level acceleration based on U.S. tide gauges and extensions of previous global-gauge analyses. Journal of Coastal Research, 27(3), 409–417. West Palm Beach (Florida), ISSN 0749- 0208.
Without sea-level acceleration, the 20th-century sea-level trend of 1.7 mm/y would produce a rise of only approximately 0.15m from 2010 to 2100; therefore, sea-level acceleration is a critical component of projected sea-level rise. To determine this acceleration, we analyze monthly-averaged records for 57 U.S. tide gauges in the Permanent Service for Mean Sea Level (PSMSL) data base that have lengths of 60–156 years. Least-squares quadratic analysis of each of the 57 records are performed to quantify accelerations, and 25 gauge records having data spanning from 1930 to 2010 are analyzed. In both cases we obtain small average sea-level decelerations. To compare these results with worldwide data, we extend the analysis of Douglas (1992 ) by an additional 25 years and analyze revised data of Church and White (2006 ) from 1930 to 2007 and also obtain small sea-level decelerations similar to those we obtain from U.S. gauge records.



Global temperature rise
All three major temperature reconstructions are mostly based on measurement made with thermometer on the ground. Seeing how those data are compiled and used is awful. Some are registered at the wrong place so they're considered rural instead of in cities, lot of them were dropped during the early 90 and they lack reliable data measurement on ocean area as it's been relying on civilian ships taking some when they have the time until not long ago.
If you think those data sets are independent and use satellite data, forget about it.

Warming oceans
See how they speak about the measurement from 1969 only. Here they can't tell if it's unprecedented or not.

Declining Arctic sea ice
Here is their latest measurements:

See how it stopped going down till 2007. Lot of the ice there as to do with dominant winds. And we know ice got a lot smaller before the fossil fuel use by humans.

Shrinking ice sheets
Where are the data from after 2006?

Glacial retreat
As more to do with deforestation than warming. Without trees to create water vapor, less water transforms to ice to get on top of those mountains.

Extreme events
Guess what? No one, even the guys giving the data dare say it's due to some climate change. See how it's worded. Using the source they give, I get this kind of plots:


Ocean acidification
And here comes the next bullet point on the politically green agenda. But what does it have to do with global warming?
