History of Atmospheric CO2 through geological time (past 550 million years: from Berner, Science, 1997). The parameter RCO2 is defined as the ratio of the mass of CO2 in the atmosphere at some time in the past to that at present (with a pre-industrial value of 300 parts per million). The heavier line joining small squares represents the best estimate of past atmospheric CO2 levels based on geochemical modeling and updated to have the effect of land plants on weathering introduced 380 to 350 million years ago. The shaded area encloses the approximate range of error of the modeling based on sensitivity analysis.
............. and life existed through all these periods!
Drawing horizontal lines through graphs proves naught, though climate change deniers seem not to think so.
No matter what, the last decade is the warmest ever recorded, and the increasing trend since 1950 is the fastest surface temperature rise in the last 600,000 years.
The global near-surface temperatures (annual values at the top, decadal means at the bottom) in the three standard data sets HadCRUT4 (black), NOAA (orange) and NASA GISS (light blue). Graph: IPCC 2013.
The slowdown in the surface warming trend since 2005 is quite well understood at this stage. Anyone with a basic knowledge of physics knows that the earth is receiving more energy that it is losing, so while temperature may slow down for periods, it must eventually also spreed up.
The basic reason is called "Conservation of Energy", the received energy cannot just disappear.
The use of a placeholder chart from a draft of the IPCC reports says a lot about the misinformation spread by denial propagandists. Here is the correct chart from the actual report.
Comparison of the three measured data sets shown at the outset with earlier IPCC projections from the first (FAR), 2nd (SAR) 3rd (TAR) and 4th (AR4) IPCC report, as well as with the CMIP3 model ensemble. As you can see the data move within the projected ranges. Source: IPCC AR5, Figure 1.4. (Small note: “climate skeptics” brought an earlier, erroneous draft version of this graphic to the public, although it was marked in block letters as a temporary placeholder by IPCC.)

France: Wind power, billions of Euros of illegal overcharging?
The European Court of Justice ( ECJ) gave its verdict on Thursday 19 December that the French tariff for purchasing wind power generated electricity represents an aid provided by French State resources.
The "Fédération Environnement Durable" notes that this judgment confirms the decision of the "Conseil d'Etat” of France, which should logically entail the repayment of the overcharging by electricity producers who have thus benefitted since 2001.
The mechanism for buying wind power generated electricity at a price guaranteed by the State would be open to review, probably as well as the ”Electricity Services Contribution” ( CSPE ), an illegal "electricity eco-tax" shown at the bottom of consumers’ electricity bills, the current rate of which is 4.5%, and has been increasing rapidly since 2001.
The (FED) asks "Electricité de France" (EDF) and other producers of electricity who have received this tax since its origin to provision for the risks reimbursing consumers for the total amount of this tax including interest. The preliminary estimates of the FED indicate that this overcharging concerning wind power alone could be as much billons of Euros i.e. hundreds of Euros for an average French household.
The FED once again declares those wind turbines, sheltering under the umbrella of ecology, are not profitable and represent an endless multibillion euro black hole for French taxpayers. They only survive thanks to the illegal charges on the bills of consumers.
So in less than 5 lines, what does this tell us about AGW?
And briefly, how accurate do you think the temperature measurements were before mercury thermometers were available, considering the margin is slight?
