The onslaught of heat records this month is so furious that it's almost impossible to keep up. The National Climatic Data Center was forced to take its reporting system offline for several days to do emergency maintenance in order to cope, but the reports are still lagging by 2 days. In just the 4 days since the previous update, data through Monday (March 19) show that the number of new daily heat records for March has more than doubled to nearly 4000, while the number of cold records has increased by less than 20, to 113. This gives an astonishing ratio of 34.8 to 1, over 50% above last August's incredible pace. For the year to date, the ratio is approaching 20 to 1, nearly 10 times the pace of the previous decade.
