March 2017 breaks temperature records, even without El Niño

The National Oceanic and Atmospheric Association, which is among the scientific organizations on the Trump Administration’s budget chopping block, has reported yet another global warming record.

March 2017 was the first time ever that a monthly average temperature was more than 1°C above average in the absence of an El Niño event. During El Niño episodes the ocean-atmosphere system in the Tropical Pacific moves in different ways that result in warmer than usual temperatures worldwide. Record warmth in the absence of El Niño suggests that human-induced climate change is to blame.

NOAA’s March 2017 report revealed that warmer and much-warmer-than-average temperatures were measured for much of Earth’s land and oceanic surfaces. The U.S. mainland, Europe, Russia, Mongolia, and Australia saw the hottest month, where departures from average temperatures were +3.0°C (+5.4°F) or more. Some regions such as western Canada and Alaska did experience a colder than usual year but no cool weather records were set.

According to a continental analysis by NOAA, four of the six continents experienced a top seven warm March since records began in 1910. Europe and Oceania had their second hottest March on record, despite the absence of an El Niño even this year.

 

The first three months of 2017, January through March, have already proven to be the second warmest on record. Only 2016 had higher average temperatures, but that was an El Niño year. Even more notably, the first three months of 2017 have been significantly warmer than January through March of 2015, which was also an El Niño year.

Zeke Hausfather is a climate scientist at University of California, Berkeley and commented on the report in an interview with the Associated Press. He said, “If El Niño were the main driver of record warmth, there is no way the last three months would have been as warm as they have been.”

Extreme weather reaches ‘uncharted territory’

Last year was a record-breaking year for climate change and not in a good way. Global temperatures set record highs for the third consecutive year and sea ice coverage worldwide shrunk by 4,000,000 square kilometers, that’s about the size of the European Union.

These extraordinary climate conditions led to extreme weather events all around the world. Among them, Hurricane Matthew in the Caribbean, the first category four storm to reach land since in 1963 and severe droughts in southern and eastern Africa. A recent report from the United Nations World Meteorological Organization found that extreme weather has carried over into 2017.

So far this winter, severe storms in the Atlantic Ocean have caused Arctic “heat waves” so that while ice cover in the region should be refreezing, many days it was close to melting. North Africa and the Arabian peninsula have seen colder than usual winter temperatures while parts of Canada and the U.S. have been much warmer than is typical.

David Carlson is the World Climate Research program director. He said, “Even without a strong El Niño in 2017, we are seeing other remarkable changes across the planet that are challenging the limits of our understanding of the climate system.”

In the month of February alone, nearly 12,000 warm temperature records were broken in the U.S.

Carlson added, “We are now in truly uncharted territory.”

Des Moines nears record for longest stretch without snow

Des Moines last saw measurable snowfall on March 4th, and unless some unlikely flurries appear tomorrow, the city will break its record for consecutive days without measurable snow.

The previous record of 277 days was set in 1889, and meteorologists say that it’s about to be broken.

“There’s no snow in the next three days, so it’s looking very very likely, unless something comes up, that we’ll beat that record,” National Weather Service meteorologist Kevin Skow said.

Warm spring broke national record

The unusually warm weather we experienced this spring turned out to be part of the warmest spring on record in the U.S.

This spring’s national average temperature was 57.1 degrees – 2 degrees higher than the previous warmest spring in 1910.
