Global Warming? Nah, Just Oregon’s Warmest Year in History. NBD.

Climate change? Go ahead, try and deny it.

Or pay attention to some of that science-type stuff coming out of OSU.

CORVALLIS, Ore. – A mild winter, an early spring and warmer-than-average temperatures every season have contributed to a record-breaking year, as 2015 will go down as the warmest in Oregon since state records began in 1895.

Oregon’s previous record high average temperature of 49.9 degrees was set in 1934 – the height of the Dust Bowl – when the entire country was plagued by hot, dry weather.

Despite a cold, icy end to December in Oregon, the average temperature in 2015 was 50.4 degrees, not only a record but far above the average yearly temperature for the 20th century, which was 47.8 degrees, according to Oregon State University’s Philip Mote, who directs the Oregon Climate Change Research Institute on campus.

“In previous years, we’ve had periods where the weather was warmer for differing spells,” Mote said. “In 2015, though, it was warmer than average almost all the way through the year.”

A combination of meteorological conditions and greenhouse gases led to the record warm year, he added.

The statistics are from the National Oceanic and Atmospheric Administration’s National Centers for Environmental Information.

Oregon was not alone in experiencing a warm 2015, according to Kathie Dello, deputy director of the Oregon Climate Service at OSU. Washington, Montana and Florida also experienced record high temperatures, and in several other states 2015 went down in the top five of all time.

It appears this will be yet another record warm year for average global temperature, Dello pointed out, and it is officially the second warmest year in the United States, despite blizzards and Arctic temperatures in the Northeast.

“If you are 31 years of age, you have not lived through a single month in which the global temperature was below average,” Dello said. “And if you are 31 and living in Oregon, you have only experienced three years here that were cooler than the 20th-century average.”

Researchers calculate the average temperature for each day by looking at the highest and lowest temperatures. If the high reaches 90 degrees and the low is 60, that day’s average temperature is 75 degrees. They then calculate the average monthly temperature, and finally, the average yearly temperature.

The average for the state is done by analyzing temperatures at a series of long-established weather stations throughout the state.

“We had a ridge of high pressure that set up and kept the weather warm and dry throughout most of the summer and fall,” Mote said. “That followed a winter in which we got nearly average precipitation, but much of it came from the south and it fell as rain instead of snow.”

Mote said the record-setting 2015 weather was a combination of meteorological phenomena and the Earth gradually getting warmer because of human activities.

Through rigorous statistical analysis, scientists are able to tease out the impacts of El Niño, greenhouse gas emissions, volcanic activity and solar activity on temperatures.

Mote said 2015 would have been a warm year because of meteorological conditions, but the 1-2 degrees (F) attributable to greenhouse gases pushed temperatures into record territory.

“There’s little doubt that the insulation of the planet from greenhouse gas emissions played a role in the warming throughout the year,” he said.

The OSU researchers say expect more of the same in 2016.

“With El Niño and the remnants of The Blob (a huge warm patch of water in the North Pacific Ocean), it should be another warm year for the Earth, and for Oregon,” Dello said.

A Note From the Publisher

Dear Readers,

The last two years have been some of the hardest in Eugene Weekly’s 43 years. There were moments when keeping the paper alive felt uncertain. And yet, here we are — still publishing, still investigating, still showing up every week.

That’s because of you!

Not just because of financial support (though that matters enormously), but because of the emails, notes, conversations, encouragement and ideas you shared along the way. You reminded us why this paper exists and who it’s for.

Listening to readers has always been at the heart of Eugene Weekly. This year, that meant launching our popular weekly Activist Alert column, after many of you told us there was no single, reliable place to find information about rallies, meetings and ways to get involved. You asked. We responded.

We’ve also continued to deepen the coverage that sets Eugene Weekly apart, including our in-depth reporting on local real estate development through Bricks & Mortar — digging into what’s being built, who’s behind it and how those decisions shape our community.

And, of course, we’ve continued to bring you the stories and features many of you depend on: investigations and local government reporting, arts and culture coverage, sudoku and crossword puzzles, Savage Love, and our extensive community events calendar. We feature award-winning stories by University of Oregon student reporters getting real world journalism experience. All free. In print and online.

None of this happens by accident. It happens because readers step up and say: this matters.

As we head into a new year, please consider supporting Eugene Weekly if you’re able. Every dollar helps keep us digging, questioning, celebrating — and yes, occasionally annoying exactly the right people. We consider that a public service.

Thank you for standing with us!
