Epic March heat wave in Midwest, Great Lakes and Northeast: link to global warming?
"Welcome to the new climate in which heat waves are pushing farther outside the envelope of what has been observed previously during the historical record. .... I’m usually very cautious about linking weather events to global warming as there is considerable natural variability in the system, but these are jaw-dropping records and such events are more likely today than 60 years ago."

"According to several top scientists, the March heat wave that has shattered records across a wide swath of the U.S. bears some of the hallmarks of global warming."

'March summer' linked to global warming
OTTAWA, March 28 (UPI) -- An early "March summer" in Canada and the United States with record high temperatures may be a symptom of global warming, researchers said.

The Making of An Extreme Event: Putting the Pieces Together
We examine how physical factors spanning climate and weather contributed to record warmth over the central and eastern U.S. in March 2012, when daily temperature anomalies at many locations exceeded 20°C. Over this region, approximately 1° C warming in March temperatures has occurred since 1901. This long-term regional warming is an order-of-magnitude smaller than temperature anomalies observed during the event, indicating the most of the extreme warmth must be explained by other factors. Several lines of evidence strongly implicate natural variations as the primary cause for the extreme event. The 2012 temperature anomalies had a close analogue in an exceptionally warm U.S. March occurring over 100 years earlier, [when CO2 levels were well below the safe level of 350 ppmv] providing observational evidence that an extreme event similar to March 2012 could be produced through natural variability alone. Coupled model forecasts and simulations forced by observed sea surface temperatures (SSTs) show that forcing from anomalous SSTs increased the probability of extreme warm temperatures in March 2012 above that anticipated from the long-term warming trend. In addition, forcing associated with a strong Madden-Julian Oscillation further increased the probability for extreme U.S. warmth and provided important additional predictive information on the timing and spatial pattern of temperature anomalies. The results indicate that the superposition of a strong natural variation similar to March 1910 on long-term warming of the magnitude observed would be sufficient to account for the record warm March 2012 U.S. temperatures. We conclude that the extreme warmth over the central and eastern U.S. in March 2012 resulted primarily from natural climate and weather variability, a substantial fraction of which was predictable.
