Hadley Centre: 7th-warmest January

Shadow off Mt. Ranier

The Hadley Centre found January to be the 7th-warmest January since 1849, +0.506°C warmer than the 1961-1990 average. (GISS found it to be the 4th-warmest.)

The 30-year trend is +0.17 °C/decade.

The 15-year trend is +0.07 °C/decade (but has a large uncertainty, of course; see this nice plot by Tamino).

The trend since last weekend is....sure to be quoted by some blogger somewhere or other as "proof" climate change isn't happening. Probably Patrick Moore.
