Another Dubious Record
We're about to hit the 30-year milestone. That's 30 years of consistent, above-average temperatures. February will mark 360 consecutive months of above average temps. That's even getting close to half my own lifetime.
Each month, the US National Climatic Data Center calculates Earth’s average surface temperature using temperature measurements that cover the Earth’s surface. Then, another average is calculated for each month of the year for the twentieth century, 1901-2000. For each month, this gives one number representative of the entire century. Subtract this overall 1900s monthly average—which for February is 53.9F (12.1C)—from each individual month’s temperature and you’ve got the anomaly: that is, the difference from the average.
