Because your statement is not accurate.

From the article:

Figure 1 shows 2007 temperature anomalies relative to the 1951-1980 base period mean. The global mean temperature anomaly, 0.57C (about 1F) warmer than the 1951-1980 mean, continues the strong warming trend of the past thirty years that has been confidently attributed to the effect of increasing human-made greenhouse gases (GHGs) (Hansen et al. 2007). The eight warmest years in the GISS record have all occurred since 1998, and the 14 warmest years in the record have all occurred since 1990.

One-half of a degree? Really? And what is a “warmer year”? The average high temperature across all 365 days? The year’s temperature taken as the temperature of the hottest day?

All this shows is that what we’ve always known about weather is stiil true — the butterfly effect keeps us from knowing anything other than what is going on right now and perhaps what will be happening in 2 days.
