In Arizona, New Mexico and Nebraska, enormous wildfires have already destroyed landscapes and darkened skies, more than a month and a half away from summer. The terrain around Boulder, Colo., was 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217 800-273-3217

John Potter, a deputy director at the city's Open Space, said that the focus now is every month.

Careful, controlled burns that clear away vegetation and help prevent wildfires from exploding into catastrophes are an ancient tool that more of the country is embracing. The changing climate is making it more difficult to carry out intentional burns.

The United States Forest Service used a record amount of prescribed fire across federal land last year, and is aiming to treat 50 million acres with fire and mechanical brush thinning over the next decade. $5 billion was put into the infrastructure law by the president to reduce the flora and fight the fires. Legal changes are being considered to encourage more burning.

With human-caused global warming heating up and drying out large parts of the country, wildfire seasons are growing longer, narrowing the windows for performing controlled fires safely. The rain and wind are making it difficult for burners. Efforts to treat more land with fire are running 888-492-0 888-492-0's in many states.

Mr. Potter said that Boulder's mountain parks department has not been able to carry out any major burns because of the dry and windy conditions. It raises a lot of concern about how bad the fires could get this summer.

He said, "Fingers crossed."

J. Morgan Varner is the director of fire research at Tall Timbers Research Station and Land Conservancy. It is difficult to plan for burning in the state because of the unpredictable climate.

For most of the past century, America's approach to fires was to put out all of them. The government believed that fire was the enemy after a series of devastating blazes in 1910. Indigenous land-management practices were considered to be pseudoscience, and the behavior of woods arsonists was considered to be.

The need for a better way has been called attention by the ferocious fires of recent years. The long focus on fire suppression has left the nation's forests overcrowded and overgrown.

Major fires in the West and the Great Plains burned four times as much as the last two decades of the 20th century, and took place twice as often, according to a recent study. Research shows that since 1979 almost every part of the globe has experienced more extreme heat and dry conditions.

Scientists say that the winter rainy season in California is getting shorter and more intense. This will give grass and brush more time to dry out and become more dangerous in the fall, while still giving them plenty of water to grow the following spring.

Some of the fires we can't put out are people don't realize.

Some states are changing. In the unlikely event that a properly planned prescribed fire goes awry, California passed a law last year letting land managers off the hook for firefighting costs. Oregon wants to do something similar. A $20 million fund is being considered by the California legislature.

Oregon changed its air quality rules in order to allow more prescribed fires. Mr. Potter said that Boulder's mountain parks department was looking into the possibility of working with Colorado officials to re-examine air quality strictures. The trade-off could be more smoke choking residents.

There is still a lack of understanding that a little smoke right now can save us from a lot of smoke later on.

Only a small percentage of prescribed fires cause injuries or damage to homes. They can leave a long lasting distrust when they do.

In Bastrop County, Texas, a prescribed fire in January was whipped into a blaze that took nearly a week to contain. An independent investigation found that the state had failed to have enough staff on site and a bulldozer for contingencies and that the conditions that day technically met the standards for a safe burn.

The people that are still here from 2011 are always nervous. After the 2011 blaze, Ms.Hernandez completed a training program in prescribed fire and started carrying out burns on her 53-acre ranch. For other residents, she said, "put it out!" and that's not the answer.

Foresters say that crews and managers trained in prescribed fire are in short supply. Many of the same people are called upon to help extinguish the fires.

Dan Porter is the forest program director in California at The Nature Conservancy. They need to take a break and see their family.

The University of California Cooperative Extension has hosted courses as part of a new program to train more people to lead prescribed fires. She said that with so many of California's catastrophic wildfires taking place on federal land, only bigger policy changes and large-scale prescribed fire projects can stop further harm.

The Forest Service restricted the use of prescribed fire on agency lands last summer to make sure resources were available to fight fires. If the fires provided ecological benefits and didn't threaten homes or infrastructure, he ordered a pause.

The temporary halt was enough to make some worry that the recent emphasis on fire could be reversed. The scale of the task is staggering if the goal is to return the land to an older ecological state, one in which frequent natural fires kept forests vibrant and resilient.

California wants to use prescribed fire on 300,000 acres of land in the next ten years. Scientists have estimated that before modern settlements transformed the landscape, more of the state burned each year. During the summer and fall, the skies were covered in smoke and haze.

It might not be practical to go back to that world in its entirety. As more human activity spreads into wilderness, societies will have to learn to accept fire in one form or another, according to a fire researcher at Texas A&M University.

It's a process that needs to happen, but we have to decide when and where.
