6 thoughts on “HadCrut Amonaly: Out and down for Feb.”

  1. The confidence intervals for the Jan/Feb anomalies overlap. [0.215,0.534] °C and [0.193, 0.497] °C, respectively. The mean values fall within each other’s CI so I don’t think we can’t say the anomaly is down.

  2. Chad…. We can say the number reported by HadCrut is lower in Feb than Jan. What we can’t know is whether the earth’s actual surface temperature was lower. So,HadCrut’s temperature anomaly is down.

  3. True. I overlooked the distinction between the actual anomaly and the estimated anomaly.

  4. Next few months will be down as well as the December to February La Nina begins to show up the global temp anomalies (2 to 4 month lag with 3 months being the most common).

    From November to December, the Nino 3.4 index fell from -0.220C to -0.730C (and to -0.970C in January). Not huge numbers but enough to drop the Hadcrut3 anomaly by 0.06C over the next two months.

  6. Look at CRUTEM3v and snow cover from Rutgers. Below trendline snow, above trendline temps. Without delving that does add up. After all, it’s where fossil fuel is burned, on land.

    UAH up agreeing with the CRUTEM3v up. Spencer/Christy might like that. Still, I think UAH showing 0.350 anomaly on 1979-1999 baseline and HadCRUT3v 0.345 on 1900-2000 baseline, just really had me look up.
