How to Compost at Home

In the old Brothers Grimm tale Rumpelstiltskin, a miller swears to the king that his daughter can spin straw into golda bold-faced lie.With the help of the eponymous imp and his magical powers, the daughter was eventually able to spew gold from her very fingers. But, she had to promise her firstborn child to him in order to receive the special talent.

In the real world there is one way to turn straw into gold, so to speak, that doesnt require any special powers or bargaining with a frightful creatureits known as composting. Creating organic fertilizer from food scraps happens to be much easier than most people think. Heres everything you need to know:

WHAT IS COMPOSTING?

In basic terms, composting means recycling plant scraps from the kitchenincluding carrot tops, potato peels, herb stems, celery fronds, eggshells, coffee grounds, used tea bagsall in the effort to minimize waste and to make garden fertilizer. The process transforms such food scraps, which would have normally ended up in the garbage, into a nutrient-rich mulch that can be added to soil and help you grow even more fruits and vegetables, thereby perpetuating the cycle. Now thatssustainability at its finest.

How it works

As organic materials decompose, they break down into nutrients like nitrogen, phosphorous, and potassiumthe same compounds plants need to thrive. Brown matter, like dead leaves and branches, provide carbon while green matter, like vegetables and fruits, provide nitrogen. Compost piles and bins ideally consist ofthree parts brown matter to one part green matter.

When these organic materials are exposed to air and water, microorganisms likebacteria, actinobacteria, fungi, protozoa, and earthwormsstart to break them down into compost. Carbon gives these microbes energy, and nitrogen facilitatesprotein synthesisa biological process where individual cells build up their specific proteins..

After these microorganisms break down the plant matter, what youre left with is a substance calledhumus(no, not hummus) which basically looks, smells, and feels like dark, moist soil. Spread a thick layer of it on top of the soil in your garden and watch your plants flourish! (Well get to more specifics below.)

COMPOSTING BENEFITS

Reduces and recycles kitchen and yard waste

One of the greatest benefits of composting is giving food scraps and yard waste another life. Instead of going straight to a landfillwhere40 percent of all food produced in the U.S. ends uptheyll serve a new purpose and nourish your garden naturally and even help you to cultivate more food.

Good for the environment

Compost can serve as a natural alternative to chemical fertilizers, which oftenseep into groundwater and end up polluting waterways.

Conditions and fertilizes soil

Compost helps give soil a softer, looser texture, which allows water and nutrients to reach the plants roots more efficiently. Its all thanks to those beneficial microorganisms, which can evenkill pathogensand prevent plant disease, according to theEnvironmental Protection Agency.

HOW TO COMPOST

Its easy to start composting at home. Whether you have a big backyard or live in an apartment with minimal outdoor space, heres how to do it.

Composting in a backyard

1. Pick a spot

The first step is to pick a dry, sunlit area outdoors and near a water source (like a garden hose). Since compost tends to be smelly, be mindful and choose a spot where the appearance or smell wont bother your neighbors. Its best to keep it far away from anywhere you eat or entertain, too. You should also avoid placing it near the house or any other wooden structures, as the decomposing materials can rot wood.

2. Dig a hole or buy a compost bin

If you dont mind letting your compost heap sit exposed, its a good idea to dig a hole in the ground to make it easier to manage. Make sure the hole measures at least 3 x 3 x 3.

You can buy a holding unit or bin at Thrive Market, likethis one here. Or you can get crafty and check out how tomake a DIY version. A closed bin with a lid also worksjust drill holes into the lid to allow air in, and add your own worms (you can pick those up at home and garden stores, too).

3. Start adding organic materials

Add compostable materials in alternating layers, starting with brown matter, then green matter, and some brown again. Try to maintain a ratio of three parts carbon (brown) to one part nitrogen (green). Too much carbon can slow down the decomposition, while too much nitrogen can make the pile slimy, smelly, and difficult to aerate.

4. Turn and add water

If you arent continually adding new matter, let it sit for five weeks. Then, turn it with a pitchfork or rake to oxygenate the mixture, and add enough water to dampen the pile. (Excess moisture hinders airflow, and too little prevents the microorganisms you need to start decomposition from thriving.) Leave it for three or four months longeritll turn into dark, moist soil, which is your key to know its ready to use.

Most people, however, tend to add new materials throughout the year. In this case, whenever you add new food waste or kitchen scraps, bury it to incorporate. Turn and moisten the pile at least every four to five weeks, but keep in mind that turning more often can really speed up the decomposition process.

Composting indoors or in an apartment

No backyard? No problem. You can make your own small-scale composting system indoorsand you dont even need worms. Heres how:

What you need

Small trash bin with a lid
Tray that fits underneath trash bin
Soil
Newspaper

Instructions

Choose a space to keep your compost bin. (Under the sink works well.)
Poke or drill a few holes on the bottom and around the rim of the bin.
Cover tray with newspaper and place the bin in the tray.
Add a layer of soil, a few inches deep, into the bin.
Add a layer of shredded newspaper into the bin.
Start adding your food scraps (green matter as listed above), along with a handful of newspaper or other brown matter as you go. (If it starts to smell bad, add more brown matter.)
Once a week, mix the pile and add a handful of fresh soil.

Youll know the compost is ready when its broken down into dark, moist soil. Use it as a top layer for potted plants or donate whatever you cant use to a neighborhood garden.

TOP COMPOSTING TIPS

Here are some important things to know before getting started to make your composting a success.

Start your compost in summer:The process works best in heata compost pile that maintains an internal temperature of 130 to 150 degrees Fahrenheit breaks down faster.
Keep a small compost bin in the kitchen:Its a convenient way to collect food scraps without having to run out to the compost pile every time you have something to add. Once your indoor bin is filled, you can throw it all into the pile at once.
Always keep a healthy balance of of carbon to nitrogen (brown to green):Remember its three parts brown to one part green. Too much or too little of either can slow things down.
The smaller the materials, the better:Before adding things into the compost, cut them down to smaller chunks to help them decompose faster.
Dont pack too much waste in:The pile needs air to breathe.
The more green matter you use, the less water you need:Remember that too much water keeps the air from flowing freely through the mixture.
Do not compost pet waste:It can contain parasites.
Do not compost meat, meat scraps, fats or oils:Otherwise pests will come crawling and potentially spread disease through the compost.
Wormsare your friends:When these guys show up, leave them be and let them do their thing. Theyll feed on your food waste and help turn it into the beautiful compost youve been waiting for.
You can compost weeds:Just make sure they dont have seeds, or else you may get some pesky plants cropping up in your garden.
Turn your pile frequently:Aerating the compost as often as every two weeks can really speed up the process.
Keep two separate compost piles:Got a lot of organic material and extra space? Starting a second pile is handy so you can let the original one break down faster while continuing your composting habit.
Add compost to the garden two to four weeks before planting:This allows time for it to meld with the soil. Once youve got it all ready to go, its time to plant theseeds. When beautiful, bright-orange carrots grow in, youll be pretty happy you didnt trash those old peels.

The most dramatic climate fight of the election is in Washington state

Voters in a progressive Pacific Northwestern state could approve the nation’s first carbon tax next week, providing a much-sought victory to proponents of legislative climate action — and possibly a model for the rest of the country.

And yet the ballot measure is at equal risk of failing spectacularly. Not because of the usual oil and coal industry foes, or even because it includes the dreaded t-word. No, the biggest obstacle in its way: other environmentalists.

An unlikely array of local and national organizations have come out against — or declined to support — Washington state’s carbon tax initiative, which will appear on the ballot as I-732. Their concerns: That a revenue-neutral carbon tax wouldn’t raise money for investing in clean energy and communities, and that people of color didn’t get a fair say in crafting the policy.

Although the split became public last year, it’s only been in the last few months that a barrage of organizations have proclaimed their opposition. Washington Conservation Voters called the measure “flawed,” while Sierra Club Washington noted its members have “deep concerns.”

Infighting is not uncommon in the environmental movement, which actually represents a fairly large and loose coalition of diverse local, state, and national interests. But the carbon tax battle in Washington state appears to stem from a recent and fundamental shift: Following the lead of more community-minded activists, the nation’s most powerful environmental groups are attempting to change their emphasis from a largely white perspective to one that is more diverse and equitable. And that means a new approach to issues like climate legislation.

“We have to find a different climate movement going forward.” –Gregg Small, Climate Solutions executive director

Many of those groups have come to the realization in recent years that they can’t fight climate change without including a broader range of people in their solutions. Attempts to remake policy so it is equitable and impactful has resulted in two main visions for how to approach climate action.

The tension between a narrowly focused environmental campaign and a newer approach that involves more consensus around a broader progressive agenda has been simmering for a long time. With I-732, it’s broken out into the open.


False starts have plagued the climate movement for years. The failed 2009 Waxman-Markey bill, which would have capped carbon emissions and created a national market for trading credits (hence the name “cap and trade”), sent the movement into existential soul-searching.

Since then, Congress has only become more hostile to climate action, meaning any successes have largely come at the state level or inside the White House. As Republicans at the national level have been less and less involved in a serious fight against climate change, the solutions have evolved without them.

Progressive states including California, New York, and yes, Washington have recently made significant strides on climate policy. Part of the movement’s post-Waxman-Markey strategy was to broaden the base of support for climate policy beyond a very white core — not by appealing to increasingly intransigent conservatives, but by listening to the people representing low-income communities and communities of color, which are disproportionately impacted by pollution and climate change.

“It isn’t just about reducing emissions,” said Green for All’s Vien Truong, who works on climate justice policy initiatives in California and other states. “It is that, but we have to move forward.” This includes bringing people to the movement who “feel the pinch of climate change” most.

Gregg Small of the Washington-based Climate Solutions noted that the cap-and-trade bill’s failure was a teaching moment. “We have to find a different climate movement going forward,” he said. “The climate community can’t do it on their own.”


Despite the recognition by many environmentalists that a new, more inclusive approach was needed, it was a divided effort that helped set the stage for the current battle in Washington state.

Two years ago, a new-school coalition of social justice and environmental groups that became the Alliance for Jobs and Clean Energy began working on a climate action proposal, gathering extensive input from community organizations.

But a smaller, grassroots-based climate group, known as Carbon Washington, got its carbon tax proposal on the ballot first. I-732 would phase in next year, tax carbon emissions at $25 per metric ton in 2018, and gradually ramp up over 40 years to $100.

What’s troubling some opponents is where that money would go: cutting the state’s sales tax by 1 percent, cutting taxes for manufacturers, and providing tax rebates to more than 400,000 low-income households. That’s allowed I-732 proponents to try to appeal to conservatives by calling it revenue neutral, but it doesn’t sit well with the Alliance-affiliated enviros.

Their four-page alternative proposal is murky on the details, though: It calls for a carbon “fee” that would redirect the revenue collected toward clean energy efforts, water quality improvement, and helping disadvantaged communities. It doesn’t cut taxes, and unlike 732, it establishes an absolute, though unknown cap on carbon emitted. The actual tax on polluters starts at $15 per metric ton, but is unclear on how it would ramp up over time. It promises some “compliance flexibility” for polluters, yet doesn’t say what that entails.

Small, a chair of the Alliance, said his group was ready to put its proposal on the 2016 ballot, but pulled its plans when 732 gained the signatures needed. Two competing ballot measures would likely have meant success for neither.

Carbon Washington met with the Alliance to figure out a compromise, but moved ahead without the full blessing of the organizations that had fought hard to bridge justice and environmental concerns. In return, there are now a slew of environmental and social justice groups slamming I-732 for not doing enough to fight climate change, not managing to be revenue-neutral, and failing on equity.

The founder of Carbon Washington, Yoram Bauman, defends his group’s approach. “I think that underneath, there’s a philosophic difference in how to provide benefits to low-income communities and communities of color,” he said. “Their approach was to fund community-directed investment. They wanted a pot of money that could be controlled by local communities to reduce emissions, create jobs, and lower pollution in communities of color. Our approach was we wanted to put money back [into the pockets of low-income] households.”

Bauman says that if his group’s measure passes, small tweaks and improvements could be made by the state legislature. But opponents say that a flawed model is not a good place to start from.

“Perfect shouldn’t be the goal,” Bauman argues. “I think folks who care about climate change need to support action on climate change. We don’t have many opportunities to take a swing at the ball, and there are serious questions about how many more years we want to wait.”


I-732 does have its share of supporters. Actor and activist Leonardo DiCaprio, 28 environmental and energy-focused groups (including the Audubon Society’s state chapter), and dozens of Republican and Democratic lawmakers and economists have endorsed it. All this has lead to one very fractured environmental community.

The Seattle-based sustainability think tank Sightline Institute is neutral on 732, but still manages a good summary of the pro-side’s position in a lengthy analysis weighing the pros and cons: “Initiative 732 does exactly what the scientists and economists prescribe: it sets a science-based, steadily rising price on pollution,” Sightline writes. “The citizens’ initiative covers most of the state’s climate pollution, makes the tax code more progressive, and is administratively elegant.” Based on a Washington Office of Financial Management projection, the 732 carbon tax would raise $2 billion in fiscal year 2019 (4 percent of the state’s annual budget), which would go back to taxpayers in various forms.

Critics, however, remain convinced that 732 it doesn’t do enough to fight climate change, nor does it address justice concerns. They also felt shut out of the process.

“I think folks who care about climate change need to support action on climate change.” –Yoram Bauman, Carbon Washington founder

“We’ve got to get it done right the first time,” said Small, who was careful to make it clear that Climate Solutions is not opposed to I-732. “Effective carbon pricing needs to really do three things: It needs to put a meaningful price on carbon to drive down pollution; it needs to invest the money generated in clean energy solutions; and it should invest in those affected by climate change.”

A coalition of environmental justice organizations penned an open letter to the Sightline Institute, saying they took issue with the group’s analysis, arguing that it serves to “denigrate our perspective and profess to speak for the interests of our communities without our consultation or knowledge.”

“People who can actually begin to be part of the solution were hoping to be part of this clean energy future,” Green for All’s Truong said. “And this carbon tax essentially shut that effort down.”

Perhaps the most unexpected argument is that the tax won’t do the intended job of cutting emissions. Food and Water Watch issued a report claiming that the model for 732, a British Columbia carbon tax, “fails to demonstrate that it has reduced carbon emissions, fossil fuel consumption, or vehicle travel, as it purported to do.”

Technically, it would be possible to alter 732 in the legislature down the line if voters approve it in November, but it’s politically unfeasible. Some environmentalists would prefer to work with what they have if it passes, but in a few cases, the critics would rather see no tax at all. Seattle public radio station KUOW asked Alliance member and OneAmerica activist Ellicott Dandy if she would regret her position against I-732 if no other carbon tax ever passed.

Her answer: “No.”


The latest polling shows a close vote. In an early October poll, 21 percent of voters were undecided. In a late-October poll from KOMO News/Strategies 360, that number is even higher, with 28 percent unsure how they will cast their ballot. How the undecideds break makes all the difference for an initiative leading with just 40 percent of the electorate, and 32 percent opposed.

If 732 fails, the lessons for environmentalists will be clear: An approach designed to appeal to more conservative sensibilities — tax cuts, revenue neutral — isn’t going to help them bring in new voices on the left, who want to be heard and play a guiding role in the process.

“Carbon pricing is incredibly difficult and maybe impossible if people don’t come together,” Small said. “Other states will face similar types of dynamics here on the policy and strategy. I hope people learn from the painful lesson we have in Washington to, you know, work it out.”

Tonight’s debate shouldn’t ignore Hurricane Matthew.

Six of the eight U.S. senators from Florida, Georgia, and the Carolinas are climate deniers, rejecting the consensus of 99.98 percent of peer-reviewed scientific papers that human activity is causing global warming. The exceptions are South Carolina’s Lindsey Graham and Florida’s Bill Nelson — the lone Democrat of the bunch.

Here are some of the lowlights from their comments on the climate change:

-Florida Sen. Marco Rubio, who does not understand the difference between climate and weather, arguing against climate action in a presidential debate in March: “As far as a law that we can pass in Washington to change the weather, there’s no such thing.”

-Back in 2011, North Carolina Sen. Richard Burr said: “I have no clue [how much of climate change is attributable to human activity], and I don’t think that science can prove it.”

-In 2014, North Carolina Sen. Thom Tillis claimed that “the liberal agenda, the Obama agenda, the [then Sen.] Kay Hagan agenda, is trying to use [climate change] as a Trojan horse for their energy policy.”

-Georgia Sen. Johnny Isakson offered his analysis  last year on whether the Greenland ice sheet is melting (it is): “There are mixed reviews on that, and there’s mixed scientific evidence on that.”

-Georgia Sen. David Perdue told Slate in 2014 that “in science, there’s an active debate going on,” about whether carbon emissions are behind climate change.

Donald Trump Says Global Warming Is a Chinese Hoax. China Disagrees.

Mother Jones

<!DOCTYPE html PUBLIC “-//W3C//DTD HTML 4.0 Transitional//EN” “http://www.w3.org/TR/REC-html40/loose.dtd”>

This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration.

Two years after President Obama and Chinese President Xi Jinping announced that their countries would work together to combat climate change, Republicans and conservatives in the United States continue to cite China’s rising carbon emissions as a reason not to bother cutting our own.

Earlier this month, Donald Trump’s economic adviser Stephen Moore claimed that limiting our carbon pollution is pointless because of China’s supposedly growing coal dependency. “Every time we shut down a coal plant in the US, China builds 10,” Moore told E&E News. “So how does that reduce global warming?”

Not only is Moore’s statement simply untrue, but the broader conservative theory behind it is badly outdated. China’s coal use and carbon emissions have dropped for the last two years. In 2015, China cut its coal use 3.7 percent and its emissions declined an estimated 1 to 2 percent, following similar decreases in 2014.

If China continues to cut its emissions, or even just keeps them at current levels, the country will be way ahead of its goal of peaking emissions by around 2030, which it laid out in 2014 and recommitted to during the Paris climate talks last December.

In part, China’s emissions are dropping because the country is undergoing a dramatic shift in the nature of its economy. For years, China had been rapidly industrializing and growing at a breakneck pace. Growth often causes emissions to rise, all the more so when a country has an expanding manufacturing sector and is building out its basic infrastructure such as highways and rail lines. Heavy industrial activity—especially making cement and steel, which are needed for things like buildings, roads, and rail tracks—can be extremely energy intensive and have a massive carbon footprint. But now, as China is becoming more fully industrialized, its growth is slower and driven more by service industries, like technology, that are much less carbon intensive.

And the Chinese government is spurring this shift to a lower-carbon economy by reducing its indirect subsidies, such as favorable lending from state-controlled banks, for coal and other carbon-heavy industries. “This is actually a correction for the economy because China is adopting a more market approach,” says Ranping Song, an expert on Chinese climate policy at the World Resources Institute, an international environmental research organization. “That will have an impact on emissions.”

We can’t know whether Chinese emissions will continue dropping every year, but China is committed to improving the energy efficiency of its economy and the cleanliness of its energy sources, and it’s already off to a strong start. “There is a set of things happening in China that will continue to change the trajectory of its emissions,” says Jake Schmidt, director of the international program at the Natural Resources Defense Council.

Here are seven things China is doing to curb its climate-warming emissions:

Limiting coal use. Just a week after that 2014 announcement with Obama, China released an energy strategy that called for capping coal consumption by 2020. China also put a three-year moratorium on new coal mines, starting this year, and it’s been shutting down existing coal mines. Cutting back on coal not only reduces carbon emissions; it combats poor air quality, which has been causing serious health problems in notoriously polluted Chinese cities such as Beijing and Wuhan.

Carbon trading. Next year, China will launch a nationwide carbon market, the world’s largest. It will cover six of the biggest carbon-emitting sectors, starting with coal-fired electricity generation. This cap-and-trade program will build on programs China has already created in two provinces and five cities.

Cleaning up cars and trucks. China is the largest car market in the world. Cutting pollution from automobiles, like cutting pollution from coal plants, is essential not just to reducing CO2 emissions but to clearing the air in cities: The government estimates that roughly one-third of Beijing’s epic smog is from automobiles. China is pulling old, inefficient cars off the road, providing incentives for buying hybrids and electric cars, and enforcing stricter fuel-efficiency standards for new cars.

Making buildings more energy efficient. Two years ago, China started issuing requirements for buildings to be given energy-efficiency upgrades. The energy savings are just beginning to be felt, but given that buildings can last for decades or even centuries, there could be a long payoff period.

Building renewable capacity. China knows it needs alternative sources of energy to replace coal, so the government is investing heavily in developing wind and solar energy. “China has emerged as a leader in renewable energy,” reported Song and one of his colleagues in a blog post in April. “Investment soared from $39 billion to $111 billion in just five years, while electric capacity for solar power grew 168-fold and wind power quadrupled.” In Paris, China promised that at least 20 percent of its energy portfolio will come from non–fossil fuel sources by 2030.

Building nuclear reactors. Whatever you think of nuclear energy, it is one of the lowest-carbon forms of electricity out there. Earlier this month, China announced it will build at least 60 new nuclear power plants within a decade.

Building high-speed rail. A wealthier citizenry in a more industrialized country will be traveling a lot more. To limit transportation emissions, China is rapidly building high-speed rail. It already has more than 11,800 miles of high-speed rail that carry 2.7 million riders daily, and expansion plans are on the drawing board.

China will surely encounter hurdles and hiccups as it continues trying to rein in its emissions. The nation’s economy has recently been slowing down for cyclical reasons, as well as the structural ones mentioned above. After years of debt-fueled corporate investment and growth, Chinese companies are paying down their debts at the same time that the government is reining in industrial overcapacity and winding down the stimulus spending that got it through the Great Recession. China’s economy will eventually pick up again, and when it does, citizens will likely buy more cars, air conditioners, and electronic goods, leading to more electricity and gasoline use and perhaps greater carbon emissions.

But the policies China is enacting are designed to ultimately create a higher standard of living without more emissions. Since China has enormous low-lying cities that will be largely underwater in a century if climate change continues spinning out of control, the country has plenty of reason to curb its emissions and has shown that it is serious about doing it. That’s true whether Republican politicians in Washington choose to believe it or not.

Cool off with your very own portable A/C unit, you jerk

By on Aug 25, 2016Share

There’s a new product coming out that promises to make summers cooler for the user — and warmer for everyone else. Meet the Zero Breeze, “the World’s First Portable, Smart, Multifunctional Air Conditioner,” according to its makers.

The Zero Breeze is a battery-powered A/C unit about the size of a boombox, as Gizmodo reports, which makes it perfect to take on the go. Park too hot? Subway make you sweat? Whip out the Zero Breeze and turn any space into your personal meat locker. “Never before have you been able to take an air conditioner wherever you go,” says the aspirational Kickstarter video.

The Kickstarter fails to mention, however, that air conditioning devices — even small, battery-powered units — increase greenhouse gas emissions and accelerate climate change. Already, air conditioners across the country release 100 million tons of carbon dioxide into the atmosphere each year, including both the emissions of the units’ coolants and their power sources. While Zero Breeze uses a more efficient coolant than traditional A/C, it’s still far more emissions-intensive than, say, a fan.

As Stan Cox, author of Losing Our Cool — a comprehensive history of air conditioning — told us: “This is another example of how we are much better at devising technologies to consume energy than we are at coming up with technologies to conserve energy.” Plus, he asks, why bother going outdoors if you’re just going to bring the indoors with you?

It’s only June, and Arctic sea ice already hit a new low

It’s only June, and Arctic sea ice already hit a new low

By on Jul 9, 2016 7:08 amShare

This story was originally published by the Guardian and is reproduced here as part of the Climate Desk collaboration.

The summer sea-ice cover over the Arctic raced towards oblivion in June, crashing through previous records to reach a new all-time low.

The Arctic sea-ice extent was a staggering 260,000 square kilometers (100,000 square miles) below the previous record for June, set in 2010. And it was 1.36 million square kilometers (525,000 square miles) below the 1981-2010 long-term average, according to the National Snow and Ice Data Center.

That means a vast expanse of ice — an area about twice the size of Texas — has vanished over the past 30 years, and the rate of that retreat has accelerated.

Aside from March, each month in 2016 has set a grim new low for sea-ice cover, after a record warm winter.

January and February obliterated global temperature records, setting up conditions for the further retreat of the Arctic summer ice cover, scientists have warned.

Researchers did not go so far as to predict a new low for the entire 2016 season. But they said the ice pack over the Beaufort Sea was studded with newer, thinner ice, which is more vulnerable to melting. Ice cover along the Alaska coast was very thin, less than 0.5 meters (1.6 feet).

The loss of the reflective white ice cover in the polar regions exposes more of the absorptive dark ocean to solar heat, causing the water to warm up. This goes on to raise air temperatures, and melt more ice — reinforcing the warming trend.

Scientists have warned the extra heat is the equivalent of 20 years of carbon emissions.

From mid-June onwards, ice cover disappeared at an average rate of 74,000 square kilometers (29,000 square miles) a day, about 70 percent faster than the typical rate of ice loss, the NSIDC said.

Sea ice loss in the first half of the month proceeded at a lower pace, only 37,000 square kilometers (14,000 square miles) a day.

The overall Arctic sea-ice cover during June averaged 10.60 million square kilometers (4.09 million square miles), the lowest in the satellite record for the month, according to the NSIDC.

There was more open water than average in the Kara and Barents seas as well as in the Beaufort Sea, despite below average temperatures, the NSIDC said.

People don’t trust hypocritical climate scientists, study finds

Snakes on a plane

People don’t trust hypocritical climate scientists, study finds

By on Jun 21, 2016 6:01 amShare

Climate scientists face a conundrum: To get their message out and conduct research, they often have to hop on a plane — but flying is exactly the sort of carbon-intensive behavior they discourage others from doing. And according to a new study from Indiana University, climate researchers lose credibility with their audience when they don’t follow their own advice.

That inconsistency is one that the general public is starting to notice. Shahzeen Attari, an author of the study, told Grist she was presenting on energy consumption a couple of years ago when an audience member asked her, “Hey, how did you come to the conference? Did you fly here?”

She was inspired to look into hypocrisy and how it changes the dynamic between climate experts and their audiences. Through two online surveys taken by almost 5,000 Americans, participants read a narrative about a researcher who offers advice on reducing personal energy use by flying less, conserving energy at home, and taking public transportation. The survey included one of several of statements about the researcher’s personal energy consumption. For example:

You later find out that the researcher flew across the country to the talk that you attended and that he/she regularly flies to lectures and conferences all over the world. Flying like this leads to increased negative climate impacts.

Then, the survey had participants rate the researcher’s credibility. When participants stated their own intentions to reduce energy use, their answers varied based on the researcher’s behavior. To put it simply: It turned out they were much more likely to take advice from someone who, well, takes their own advice.

But the effect wasn’t equally strong for all energy-consuming activities. According to the research, people are more forgiving of a climate scientist who flies often than one who lives in an enormous mansion. “If I live in a huge, gargantuan house … my credibility completely plummets,” Attari says. She suspects this is because people are more likely to understand that climate researchers are required to fly for work, while they have more choice over what they do at home.

Some climate researchers have started to limit their flights, but it’s really hard, Attari says. (Read the account of one climate scientist who decided not to fly.) During our interview, she admitted that she couldn’t talk very long since she had to catch a plane. “I know it’s ironic,” she said.

In a time where climate advocates like Leonardo DiCaprio and Al Gore have been lambasted for private-jet lifestyles, it shouldn’t come as a surprise that communicating with the public about climate change is a tricky business. Attari’s advice for climate experts: “Talk to your audience about your own carbon footprint and the ways you’ve been able to actually change it.”

Trees lining California streets are worth an extra $1 billion a year

Trees lining California streets are worth an extra $1 billion a year

By on Jun 16, 2016Share

It’s not easy to price a tree, but a group of researchers from the U.S. Forest Service and U.C. Davis have tried to do exactly that.

Working with a dataset of about 900,000 trees that line California’s public streets, the group sought to place a dollar value on the services those trees perform, which include “energy savings, carbon storage, air pollutant uptake, and rainfall interception.”

All told, the researchers estimate the trees contribute about $1 billion annually — nearly $111 per tree for each of the state’s 9.1 million street trees.

They found that the trees are worth $839 million annually alone based on the value they add to property, by providing more privacy and better views.

Trees help us fight climate change, too. The study values their carbon-storage abilities at $10 million each year and their energy savings (from the shade they provide) at $101 million. Between carbon sequestration and emissions reductions from energy savings, the state’s street trees avoid nearly 600,000 metric tons of CO2 emissions annually, which is like removing 120,000 cars from the road.

Trees also take pollutants like ozone and particulate matter out of the air — adding another $18 million to the tally.

Going forward, urban foresters can use the study to help guide what types of trees pack the maximum economic and environmental impact and, importantly, where to plant more of our leafy friends. Tree-lined streets and public green spaces tend to be located in the affluent, whiter parts of town.

The researchers write that there’s enough vacant space for another 16 million street trees to be planted in the state.
