Erica Fleishman, director of Oregon State University’s Oregon Climate Change Research Institute, said unusual weather events, such as the cold spell that Portland and the Willamette Valley experienced over the weekend, could become more common with climate change.
Usually, Fleishman said, cold Arctic air is kept up north during the winter by a jet stream. But climate change can destabilize this stream, allowing the cold air to dip south into the United States.Across the country, ongoing inclement weather is forcing states like Texas to ask hard questions about whether their power supply is prepared for future environmental conditions. ‘
