From The Climate Mobilization, July 2021: Destructive heat waves in the Northwest cooked shellfish on the shore and are estimated to have killed more than a billion marine animals. Hundreds of people, including unhoused individuals, elderly people and farm workers, died in the U.S. and Canada during the heatwave.
Already an endangered species, salmon in the Sacramento river may not survive this summer’s heatwave as water temperatures rise beyond what the fish can tolerate.
Extreme heat is bringing wildfires to the west, where air quality is poor and Native American tribal land is threatened. In Lytton, British Columbia temperatures reached 121 degrees Fahrenheit in July, followed closely by a devastating fire that burned 90% of the town.
In Pakistan, temperatures have risen to over 125 degrees Fahrenheit. In this heat, combined with humidity, the body’s natural cooling system (sweat) no longer functions. In areas like Pakistan’s Sindh province, where air conditioning is scarce, heat can turn deadly for people who are left exposed.
On the east coast of the US, New York City saw flooding from tropical storm Elsa that demonstrated vulnerabilities in public transit and aging infrastructure — commuters waded through contaminated water to get to subway platforms, and others were rescued from cars on flooded roadways. The climate emergency is making conditions unsafe for millions of people.
New home construction in Tucson, Arizona will have to include charging outlets for electric vehicles due to changes in building code passed this June. This change comes as part of City of Tucson’s Electric Vehicle Roadmap, which has been developed in response to Tucson’s declaration of climate emergency last year. The Tucson landfill is also getting a new name and a new mission in the city’s response: the Los Reales Landfill will now be known as the Los Reales Sustainability Campus and it will serve as a hub for sustainability-related activities to help the city achieve carbon-neutrality by 2030 and zero-waste by 2050. Details about this effort can be found in a presentation from the city.
New Jersey has approved the largest off-shore wind installation in the U.S., which is projected to power over 1 million homes by the end of the decade.
The legislature of the state of Maine has divested the state’s pension funds from fossil fuel investments, the first state government to take this step. In Maine a statewide ban on disposable plastic shopping bags has taken effect as of July 1, and a new bill signed by Maine governor Janet Mills this week will shift the cost of plastic packaging disposal by creating an Extended Producer Responsibility Program to charge waste producers and channel funding to local recycling programs.
The state of New York has passed a bill to encourage the use of concrete that has a lower carbon footprint in new public-sector construction. Proponents of the bill hope that new infrastructure spending across the nation will employ materials with less environmental impact, particularly concrete, which contributes roughly 7% of global greenhouse gas emissions.
After a disappointing attempt by Democratic state legislators to ban hydraulic fracturing in California, Governor Gavin Newsom announced in April that he would use regulatory action to ban all new fracking permits in the state by 2024. In 2021 approvals for new wells have gone down 90%. Though fracking makes up a small percentage of fossil fuel extraction in California, banning the practice in the state would eliminate this heavily polluting practice and make California the largest oil-producing state to ban fracking.
There is increasing research proving that perhaps one of the most effective technologies to combat rising temperature levels are trees. Mostly due to deforestation for beef and soy production, scientists have confirmed that the Amazon has changed from carbon sink (a place that absorbs carbon) to carbon source, a truth that has enormous implications for global carbon levels.
can lower urban temperatures 10 lifesaving degrees, scientists say.

DES MOINES — The trees were supposed to stay.
It didn’t matter that the owners of the squat building alongside were planning to redevelop the property. The four eastern red cedars stood on city land, where they had grown for the better part of a century.
“There’s no way these trees are coming down,” Shane McQuillan, who manages the city’s trees, recalled thinking. “The default position for us is, you don’t take out big trees to put in small trees.”
Here’s why: At a time when climate change is making heat waves more frequent and more severe, trees are stationary superheroes. Research shows that heat already kills more people in the United States than hurricanes, tornadoes and other weather-events, perhaps contributing to 12,000 deaths per year. Extreme heat this week in the Pacific Northwest and Canada has killed hundreds.
Trees can lower air temperature in city neighborhoods 10 lifesaving degrees, scientists have found. They also reduce electricity demand for air conditioning, not only sparing money and emissions, but helping avoid potentially catastrophic power failures during heat waves.Climate Fwd A new administration, an ongoing climate emergency — and a ton of news.

“Trees are, quite simply, the most effective strategy, technology, we have to guard against heat in cities,” said Brian Stone Jr., a professor of environmental planning at the Georgia Institute of Technology.

So, in Des Moines, Mr. McQuillan worked with the property owners and city planners to find a way to redevelop while keeping the trees.
But one day several months later, he got word that a crew was taking them down.
Mr. McQuillan raced to the site, just a couple blocks from his office. One tree had already been cut to a stump, and another was almost down. Mr. McQuillan halted the work and fought to stay calm. At first he assumed someone had taken matters into their own hands. But after investigating, he came to believe it was simply a mistake; the property had been leased for a restaurant and the tenants seemed sincerely unaware of the agreement.
“There’s a defeated feeling,” Mr. McQuillan said.
They were two losses in an enormous struggle. Versions of this story are playing out in cities across the country, including Boston, Atlanta, Cleveland, Chicago, Houston, Spokane and Los Angeles, according to the United States Forest Service.
Despite longstanding and ongoing efforts across the country to plant trees, communities in the United States are not adding to their total number or even maintaining it. Research shows that American cities and towns lose the canopy of 36 million trees every year.
‘A challenge to get trees to thrive in the city’
Considering the cast of characters in Des Moines, its urban forest should be thriving. The longtime mayor is an environmentalist. The director of public works hails trees as “the only infrastructure that add value over time.” A nonprofit group plants and tends the next generation of trees while giving green jobs and training to local teenagers.
In recent years, though, the larvae of an iridescent green beetle that arrived from across the ocean, the emerald ash borer, have claimed 6,000 of the city’s 8,000 public ash trees. A storm last year took out about 500 more of all kinds. Another big factor is the everyday losses: The tree felled to repair a water line underneath. The homeowner who removed a tree to build an extension or get more sun on the lawn. Countless new developments where trees were in the way. These are often mature trees whose canopy will take decades to replace.
Then, there are the bare-branched victims whose cause of death can only be guessed at: Not enough water? The extra-cold winter combined with all that street salt?
“It’s a challenge to get trees to thrive in the city,” said Phillip Rodbell, who leads a Forest Service team studying the social, economic and ecological impact of urban trees.
At the same time, American cities are facing a heat crisis: The largest are warming at twice the rate of the planet as a whole.
‘It’s hard for us to think of trees as actual infrastructure’
On an afternoon that felt too sweltering for June, a 14-year-old named Kiara Wright bent over a young honey locust along a busy road in Des Moines, carefully splashing water from two five-gallon buckets into the dry soil. The city was in drought, and abundant water is critical to trees for at least two years after the shock of transplanting.
Earlier in the spring Kiara had helped plant that season’s 500 trees, becoming fond enough of them to name a few: Sparkles, Linden, José. Now she was watering, mulching and pulling weeds for $10 an hour. Over the course of the summer, her small team would also learn about financial literacy and shadow people in various green jobs.
“We grow the trees and we grow the teens,” said Kacie Ballard, who coordinates the program for Trees Forever, a nonprofit group that is now planting almost all of the city’s street trees. “It’s cheesy but it’s true.”
Along with the environmental benefits of trees come economic opportunities.
“This is a field where the employers are begging,” said Jad Daley, president and chief executive of American Forests, a nonprofit group. “There is definitely a job waiting.”
Planting in Des Moines will resume in the fall, focusing on formerly redlined communities most in need of trees. Around the country, racist policies have left these neighborhoods especially bare and hot.
Leslie Berckes, director of programs at Trees Forever, hopes to get 1,000 trees in the ground by the end of the year, surpassing an agreement with the city. But the number still feels bittersweet. Four times that many are needed, on public and private land, to reach a state goal of increasing canopy 3 percent by 2050. Instead, she fears their efforts are not enough to stay even.
“We could be keeping pace if we wanted to,” Ms. Berckes said. “We need more money. I know it’s so boring to say.”
By all accounts the mayor, Frank Cownie, is trying. Des Moines has increased its $200,000 tree planting budget to $300,000 next year and $450,000 the following, with a goal of reaching $1 million. Its forestry department, with a budget of $2 million, employs a team of 13 arborists, up from 11 a couple years ago, who prune the city’s trees, extending their lives.
But it’s a tricky balancing act.
“You’ll hear, ‘Why are you doing this, you should be creating homes for the houseless,’” Mayor Cownie said. “Which we are.”
The crux of the problem, according to scientists and environmental planners, is that Americans, from everyday citizens to government officials, are often not fully aware of the benefits that trees provide.
In addition to reducing heat, trees filter out air pollution, suck up storm water, store carbon, nurture wildlife and even improve people’s mental and physical health.
“It’s hard for us to think of trees as actual infrastructure rather than an amenity, and because of that, we don’t allocate sufficient funds,” said Dr. Stone of the Georgia Institute of Technology. “If we think about it as actual infrastructure on par with investing in roads and sewers and everything else, those costs will become more acceptable to us.”
‘Trading one risk for another’
A tree’s shade, that sweet relief from solar radiation, is only part of its cooling power. Trees also evaporate water, pulling it from the ground and releasing it into the air through their leaves. That’s why walking through a forest, or just sitting in a playground surrounded by several large trees, feels more refreshing than the shade of a lone tree.
Carefully positioned trees can reduce a home’s energy costs by 25 percent, according to the Department of Energy. Nationwide, urban trees offer an estimated $18.3 billion in air pollution removal, carbon sequestration, lowered energy use in buildings and reduced emissions from power plants.
Still, across the country many people see trees as a nuisance or liability. They drop nuts, seeds and leaves. They buckle sidewalks. They are accused of destroying pipes — wrongly, according to scientists, who say that pipes crack from age, which only then leads nearby trees to send roots toward the leaking water. Some towns and cities avoid the perceived hassle altogether by not planting on the strip of lawn between the sidewalk and the street.
Occasionally, their limbs break or they blow over, posing real danger. With climate change increasing the intensity of storms, David Nowak, a senior scientist with the Forest Service who studies urban trees, acknowledges the risk. Trees close to houses need to be especially well monitored for weakness. But he points out that trees also block wind, reducing the force of storms.
“You’re trading one risk for another,” Dr. Nowak said. “Branches falling, and having to clean up branches, versus having to clean up broken rooftops.”
One major challenge is persuading property owners, who own a large share of the land in cities and towns, to plant and maintain trees in their yards. It’s important to choose the species carefully. Large shade trees offer more cooling and carbon storage than small ornamentals. For wildlife, oaks are usually the best bet, according to Doug Tallamy, a professor of entomology at the University of Delaware. They feed more than 900 species of caterpillars, which, in turn, feed birds, whose populations have plummeted.
Incentives can help, but tight budgets often keep them modest. In Louisville, Ky., which threw itself into planting more trees after it was found to be the fastest-warming large city in the country, residents can get a $30 “treebate,” up to three per household, for planting certain shade trees.
The director of public works in Des Moines, Jonathan Gano, came up with an idea to give away “tiny trees,” seedlings that look like mere sticks with roots. Once a year, residents can pick up five each.
“They’re tiny, yes,” Mr. Gano said. “They’re also practically free,” costing the city $1 per seedling.
“You could have 99 percent mortality and still be in the money 20 years from now on canopy,” Mr. Gano said. “I planted a bunch on my property and about 50 percent of them have survived. One of them’s 11 feet tall now.”
