People urged to stay inside across California, Nevada, Oregon, South Dakota

Thousands of residents across parts of California, Nevada, Oregon, and South Dakota have been advised to stay indoors, as levels of fine particle pollution (PM2.5) will have reached “unhealthy” levels as of January 12, 2026, at 6 a.m. ET, the Environmental Protection Agency’s (EPA) AirNow Map shows.

The EPA is urging people in sensitive groups, including the elderly, children, and those with certain health conditions, to completely avoid prolonged or intense outdoor activities. Everyone else should reduce their participation in long or intense outdoor pursuits.

This is because physical activity causes people to breathe harder and faster, which means the fine particulate matter can penetrate deeper into the lungs if people are exercising outdoors.

The EPA warns, “Your chances of being affected by particles increase the more strenuous your activity and the longer you are active outdoors. If your activity involves prolonged or heavy exertion, reduce your activity time—or substitute another that involves less exertion. Go for a walk instead of a jog, for example.”

What Do ‘Unhealthy’ Levels of PM2.5 Mean?

PM2.5 are tiny, inhalable particles of pollution, 2.5 micrometers or less in size (smaller than a strand of hair), that are considered to be one of the most dangerous forms of air pollution, according to the EPA.

This is because they get deep into the lungs—and sometimes even the bloodstream—triggering or exacerbating certain health conditions, like asthma, or causing symptoms ranging from coughing and nose, eye, and throat irritation to shortness of breath and chest tightness.

The Environmental Protection Agency (EPA) uses the Air Quality Index (AQI) to report and classify air quality across the United States. The AQI is a standardized scale ranging from 0 to 301+, which categorizes air quality into the following levels:

Good: 0 to 50—Air pollution poses little or no risk to the public
Moderate: 51 to 100—Some pollutants may pose a moderate health concern for a very small number of unusually sensitive people
Unhealthy for sensitive groups: 101 to 150—Members of sensitive groups (children, elderly, people with respiratory or heart conditions) may experience health effects; the general public is less likely to be affected
Unhealthy: 151 to 200—Everyone may begin to experience health effects; members of sensitive groups may experience more serious effects
Very Unhealthy: 201 to 300—Everyone may experience more serious health effects
Hazardous: 301+—Health warnings of emergency conditions; the entire population is likely to be affected

What Causes PM2.5?

PM2.5 can come from a variety of sources, ranging from wildfires and smokestacks to emissions from vehicles and power or industrial plants.

IN RESPONSE: Cortez Masto lands bill would keep the proceeds in Nevada

A recent Review-Journal letter to the editor mischaracterized Sen. Catherine Cortez Masto’s Southern Nevada Economic Development and Conservation Act, also known as the Clark County Lands bill. As the former executive director of the Nevada Conservation League, I wholeheartedly support this legislation, so I wanted to set the record straight.

Sen. Cortez Masto has been working on this bill for years in partnership with state and local governments, conservation groups like the NCL and local area tribes. It’s true that the Clark County lands bill would open 25,000 acres to help Las Vegas grow responsibly, while setting aside 2 million acres for conservation. It would also help create more affordable housing throughout the valley while ensuring our treasured public spaces can be preserved for generations to come.

What is not correct is that the money from these land sales would go to the federal government’s coffers. In fact, the opposite is true.

The 1998 Southern Nevada Public Lands Management Act is a landmark bill that identified specific public land for future sale and created a special account ensuring all land sale revenues would come back to Nevada. In accordance with that law 5 percent of revenue from land transfers goes to the state of Nevada for general education purposes, 10 percent goes to the Southern Nevada Water Authority for needed water infrastructure and 85 percent supports conservation and environmental mitigation projects in Southern Nevada. This legislation has provided billions to Clark County and will continue to benefit generations of Southern Nevadans. Sen. Cortez Masto’s lands bill builds upon the act’s success.

So here’s the good news: All of the money generated from land made available for sale under Sen. Cortez Masto’s bill would be sent to the special account created by the 1998 law. Rather than going to an unaccountable federal government, the proceeds would continue to help kids in Vegas get a better education, bolster outdoor recreation and modernize Southern Nevada’s infrastructure.

I know how important it is that money generated from the sale of public land in Nevada stay in the hands of Nevadans, and so does the senator. That’s why she opposed a Republican effort last year to sell off 200,000 acres of land in Clark County and other areas of the country that would have sent those dollars directly to Washington.

Public land management in Nevada should benefit Nevadans. We should protect sacred cultural sites and beloved recreation spaces, responsibly transfer land for affordable housing when needed and ensure our state has the resources it needs to grow sustainably. I will continue working with Sen. Cortez Masto to advocate for legislation, such as the Clark County lands bill, that puts the needs of Nevadans first.

Paul Selberg writes from Las Vegas.
