The Pacific Northwest is currently grappling with a perilous heat wave that has turned out to be more than just uncomfortable. Reports indicate that at least 63 lives have been lost in Oregon alone since these unprecedented temperatures began. Roads are deteriorating, paint is peeling from buildings, power lines are melting, and approximately 33 million individuals are under urgent heat advisories. Our infrastructure simply isn’t equipped to handle the extreme heat that much of the country is facing. The culprit? Climate change, exacerbated in this instance by a phenomenon known as a “heat dome.”
What is a Heat Dome?
A heat dome occurs when a large mass of warm air becomes trapped in a wavy, elongated jet stream, leading to unusual temperature spikes. The high-pressure ridge currently sitting over the Pacific Northwest has formed what meteorologists call an Omega block (named for its resemblance to the Greek letter Omega), effectively holding hot air in while pushing it downward. This downward-moving air compresses, raising temperatures even further and generating heat through descending winds. In essence, a heat dome functions like a Dutch oven, trapping heat and creating a stifling environment.
Contributing to this heat dome is the fact that climate change has already raised baseline temperatures in the Pacific Northwest by 3-4 degrees Fahrenheit since the Industrial Revolution. While it may be tempting to make light of the situation—perhaps joke about sweaty days or the things we could cook on sidewalks—this is no laughing matter.
The Impact of Climate Change
As we witness a rise in extreme weather events, it’s clear we must prepare for their increasing frequency. The situation in the Pacific Northwest would typically be regarded as a once-in-a-thousand-year event in a stable climate; however, the rapid pace of climate change is anything but typical. It’s not some divine retribution causing ice storms in Texas or heat waves in Oregon; it’s the result of human actions—excessive fossil fuel consumption, deforestation, urban sprawl, and industrial farming practices that prioritize quantity over sustainability. The meat industry, in particular, is a leading contributor to greenhouse gas emissions and global warming.
We must brace ourselves for the adverse impacts of climate change and hold ourselves—and our governments—accountable for taking action to mitigate its effects. Solutions exist, but they require a fundamental shift in how we build homes, consume energy, and manage our carbon footprints. Transitioning to renewable energy sources like wind and solar power, opting for electric vehicles or public transportation, supporting sustainable businesses, and enhancing home energy efficiency are all crucial steps. Additionally, we can help combat climate change by planting trees and investing in carbon capture technologies.
It may seem daunting, especially for those struggling to make ends meet, but collective action is essential if we want to survive the summer—or any season—safely.
Current Conditions and Health Risks
Currently, many areas in the Pacific Northwest are experiencing temperatures that are 30 degrees above the seasonal average. Not everyone has air conditioning, and many are hesitant to visit cooling centers. While some are heading to beaches to escape the heat, public pools in places like Portland, Oregon, have had to close due to unsafe temperatures for staff. Yes, it’s too hot even for swimming!
During these extreme heat events, recognizing the signs of heat exhaustion and heat stroke is crucial. Symptoms may include dizziness, headaches, nausea, muscle cramps, fainting, heavy sweating, hot and red skin, and confusion. According to the CDC, staying cool is critical; if possible, remain indoors in air-conditioned environments, stay hydrated, and avoid strenuous activities. To cool down, drink plenty of cold water, apply damp towels to your forehead and neck, mist your skin with cool water, and block out heat and light by covering windows with blankets or dark paper. Additionally, be sure to look out for pets, children, the elderly, and anyone with health conditions that may heighten their vulnerability to heat.
Drought Conditions and Fire Risks
Many are also anxious about the pervasive drought conditions worsening the heat. The ongoing heat is intensifying dry spells, creating a dangerous cycle. As of June 22, nearly 80% of the Northwest was reported to be in drought, just as fire season is approaching, which is expected to be “above normal.” So, let’s leave the fireworks to the professionals, avoid fire pits, and certainly skip any gender reveal parties. Let’s be smart and considerate, okay?
People are feeling hot, uncomfortable, and anxious; their homes and livelihoods are on the line. While temperatures are projected to cool down soon, we face a significant challenge ahead if we want to avoid making heat waves the norm.
