Now that the La Nina is over, the lower atmosphere is heating up noticeably. GISS just reported the second warmest May in their records, with a surface anomaly of +0.65°C, which is equal to 1998's anomaly within measurement error.
The lower troposphere is warming too -- at the moment my estimate of June's anomaly, based on the first half of the daily UAH measurements, is +0.46°C, which would rank 2nd after 1998. (My method, which is only a bit more sophisticated than monkeys throwing poo at a wall, is explained here; so far (viz. this year) it's generally been good to about ±0.05°C, and the average could still swing by several hundreds of a degree by the end of the month. Note UAH's caveat.)
If there is a strong El Nino later this year -- chances are said to be 50-50 -- this AGW skepticism thing could be over by Christmas.
