Before that, the ONLY TIME that both CO2 and temperatures have risen at the same time in the past 150 years was the 27 year period from 1971 through 1998. At every other time, either CO2 was steady or decreasing (while temps rose) or temps were declining or steady (while CO2 rose.)
Neither makes a good trend - as far as the AGW extremist money crowd is concerned. Yes, he does not plot the graphs, and he should have: But the graphs (on several US national sites!) have been tweaked by the AGW extremists:
1) Surface temperatures graphs were previously “corrected” by Hansen himself at NASA - these corrections were needed to adjust for the heat bubble around urban cities - which are up to 10-12 degrees F hotter than farmlands: But Hansen’s corrections were (on average) too much early on (before 2000) and too little (post 2000): the result makes temperatures before 2000 seem low and those past 2000 too high, both of which makes GW seem MUCH larger than it actually is. You MUST accept ONLY graphs that use the “re-corrected” values assigned after 2006 - when his charade was discovered by a team of statisticians (not “peer-reviewed scientists!) from Canada.
2) Graphs of satellite data for the troposphere (the most accurate air temperature data) are truncated before 1985: this implies that temperatures in the mid30’s were NOT hotter than now, and that the very low points (cycling temps from 1950 to a low in 1972 back towards a high in 1998 were ONLY RISING from 1980 to 1998. This is a very, very different impression than what really happened.
3) Surface temperatures are greatly affected by the removal/failure/loss of many hundred Soviet temperature stations in Siberia and North Russia in early 1990-1992. Thus, if you average many thousands surface readings from 1950 through 2006, but you are NOT recording many hundred low-temperature readings from 1992 through 2006, the overall average reading will appear higher after 1992. This doesn’t mean the rest of them are wrong, but it DOES mean that the average temperature will be higher after 1992 - regardless of what the real air temps are doing.
4) But the measured temperatures ARE wrong in many places: These are the thermometers placed near parking lots, behind buildings, out in the sun without specified covers and sun shields. Others are near air-conditioner vents, fans, motors, and industrial areas. ALL of these violate siting requirements, but NASA (and other AGW agencies of the federal government) violently/viciously refuse to give out locations of their stations to verify how many are legally sited in legal covers.
