Al Gore admits he advocated ethanol knowing it was a bad idea because he was running for president and needed farmers' votes.

"2012 in perspective so far [multi-year data follows]
With the UAH anomaly for April at 0.295, the average for the first third of the year is (-0.09 -0.112 + 0.108 + 0.295)/4 = 0.05025. If the average stayed this way for the rest of the year, its ranking would be 12th. This compares with the anomaly in 2011 at 0.153 to rank it 9th for that year.
With the RSS anomaly for April at 0.333, the average for the first third of the year is (-0.058 -0.12 + 0.074 + 0.333)/4 = 0.05725. If the average stayed this way for the rest of the year, its ranking would be 21st. This compares with the anomaly in 2011 at 0.147 to rank it 12th for that year.
With the GISS anomaly for April at 0.56, the average for the first third of the year is (0.34 + 0.39 + 0.46 + 0.56)/4 = 0.4375. If the average stayed this way for the rest of the year, its ranking would be 13th. This compares with the anomaly in 2011 at 0.514 to rank it 9th for that year.
With the Hadcrut3 anomaly for March at 0.305, the average for the first three months of the year is 0.239. If the average stayed this way for the rest of the year, its ranking would be 18th. This compares with the anomaly in 2011 at 0.34 to rank it 12th for that year.
With the sea surface anomaly for March at 0.242, the average for the first three months of the year is 0.225. If the average stayed this way for the rest of the year, its ranking would be 14th. This compares with the anomaly in 2011 at 0.273 to rank it 12th for that year.
So on all five of the above data sets, for their latest anomaly average, the 2012 average is colder than their 2011 average value.
On all data sets, the different times for a slope that is flat for all practical purposes range from 10 years and 7 months to 15 years and 6 months. Following is the longest period of time (above 10 years) where each of the data sets is more or less flat. (For any positive slope, the exponent is no larger than 10^-5, except UAH which was 0.00055 per year so it could be questioned whether it can be considered to be flat.)
1. RSS: since November 1996 or 15 years, 6 months (goes to April)
2. HadCrut3: since January 1997 or 15 years, 3months (goes to March)
3. GISS: since March 2001 or 11 years, 2 months (goes to April)
4. UAH: since October 2001 or 10 years, 7 months (goes to April)
5. Combination of the above 4: since October 2000 or 11 years, 6 months (goes to March)
6. Sea surface temperatures: since January 1997 or 15 years, 3 months (goes to March)
7. Hadcrut4: since December 2000 or 11 years, 5 months (goes to April using GISS. See below.)
See the graph below to show it all for #1 to #6.
For #7: Hadcrut4 only goes to December 2010 so what I did was get the slope of GISS from December 2000 to the end of December 2010. Then I got the slope of GISS from December 2000 to the present. The DIFFERENCE in slope was that the slope was 0.005 lower for the total period. The positive slope for Hadcrut4 was 0.004 from December 2000. So IF Hadcrut4 were totally up to date, and IF it then were to trend like GISS, I conclude it would show no slope for at least 11 years and 5 months going back to December 2000. (By the way, doing the same thing with Hadcrut3 gives the same end result, but GISS comes out much sooner each month.) See:
