Between the brouhaha over Super Freakonomics and an article from the BBC, there seems to be a lot of discussion about whether or not the climate is actually warming now. It didn't seem to matter that NOAA stats indicate warming, and that the Union of Concerned Scientists, as well as numerous prestigious climate scientists' work all show that the trend is toward more warming. Well, the Associated Press put their own statisticians on the case and found, yes, the world is indeed still warming: No Declines Over Time
In their analysis, the AP gave temperature stats to four independent statisticians, without telling them what the actual numbers represented, and asked them to look for trends. They all found "no declines over time."
According to NOAA data the last 10 years are the warmest 10-year period of the modern record. The AP looked at NOAA's year-to-year ground temperature changes for the past 130 years, as well as the past 30 years of satellite-recorded temperatures.
Distinct Decades-Long Upward Trend
The result was "a distinct decades-long upward trend in the numbers," without a significant drop in the past 10 years in either set of stats -- any ups and downs in the past decade "repeat random variability in data as far back as 1880."
The original AP article goes into greater debunking detail of the debunking of global warming, should you want need further convincing, but let's put this global cooling chatter to rest.
