Don’t tell Trump, but meeting with North Korea could help environment

You might have heard that Donald Trump and Kim Jong-un had a strange, historic meeting this weekend in Singapore, leading pundits to furiously analyze a resulting joint statement for hints about the future of North Korean denuclearization and U.S. sanctions. But there was one overlooked issue that could have surprising consequences: the summit’s potential impact on the environment and climate change.

A thawing of relations between North Korea and the U.S. could open up opportunities for more research and environmental support. North Korea’s participation in the Paris climate agreement is at least partly due to a desire for access to the United Nations Framework Convention on Climate Change’s agricultural and energy know-how. And the U.S. summit could mark the start of more ecological and technical exchange with the “hermit kingdom.”

“North Korea has a direct existential reason for wanting to address issues of environmental degradation,” says Benjamin Habib, lecturer in international relations at La Trobe University in Melbourne, Australia. Since the mid-1990s, North Korea has endured decades of drought, flooding, and deforestation, at times pushing people in the famine-vulnerable nation to starvation.

Due to poor agricultural techniques and limited sources of fuel — some trucks in the country actually run on wood — North Korea has lost over 25 percent of its forest cover. And in 2016 alone, flooding from Typhoon Lionrock displaced tens of thousands of its citizens.

After Syria’s entry into the Paris agreement in late 2017, the U.S. remains the only country on Earth not in the climate accord. Even North Korea — with its prison camps, rogue nuclear testing, and authoritarian propaganda — has pledged to reduce its CO2 emissions to support global climate goals. Last June, North Korea’s Ministry of Foreign Affairs critiqued Trump for backing out of the agreement, calling it a “silly decision.”

Habib argues that the fight against deforestation can serve as a less-politicized common interest for North Korea, South Korea, and the U.S. to unite behind. “The political window of opportunity is now open for environmental capacity-building in a way that it wasn’t before,” he says.

Of course, the future of U.S./North Korea diplomacy is far from certain, thanks to two wildly unpredictable leaders. And North Korea is sitting on more than 100 billion tons of coal. If sanctions are lifted, those reserves could be sold on the world market, with deleterious effects for the global climate. (China used to buy coal from North Korea but suspended those imports last year over the country’s nuclear testing.)

But still, a meeting between two historically narcissistic world leaders might net a positive effect on environmental outcomes? We’ll take what we can get, 2018.

The planet wants you to stop eating so much meat and dairy

A new, comprehensive analysis came to a regrettable conclusion for all you cheeseburger lovers out there: The earth has a beef with your meat and dairy consumption.

A vegan diet is “probably the single biggest way to reduce your impact on planet Earth,” the University of Oxford’s Joseph Poore, the lead researcher, told the Guardian. He says that giving up meat and dairy makes a “far bigger” difference than cutting down on flying or getting an electric vehicle.

The researchers found that meat and dairy production is responsible for 60 percent of greenhouse gas emissions from agriculture. The study, published in the journal Science, represents the most comprehensive analysis of farming’s environmental impact to date. It assessed the production of 40 different foods (representing 90 percent of all that we eat) at 40,000 farms across the world, analyzing their impact on land use, greenhouse gas emissions, water use, and air and water pollution.

If we gave up meat and dairy, we could reduce farmland by more than 75 percent worldwide and have enough food for everyone to eat, the analysis shows.

The results support what the science had already been telling us, even though the researchers took a new approach of gathering data farm by farm. Previous work had used national data to quantify farming’s impact. “It is very reassuring to see they yield essentially the same results,” Gidon Eshel, a Bard College food researcher who wasn’t involved in the Science analysis, told the Guardian.

While this is a confirmation of what we’ve been hearing for years, we also know that getting the entire world to switch to veganism is a hard sell. And in fact, after a few years of decline, meat eating is on the rise again: Americans are predicted to eat a record-shattering amount of red meat and poultry this year. It’s never too late to join the reducetarian movement, meat lovers.

There’s been a mysterious rise in ozone-destroying emissions

Thought the ozone layer was safe? Think again.

CFC-11 is an ozone-depleting chemical whose phase out agreed upon in the ’80s and has been under an international ban since 2010. That’s why National Ocean and Atmospheric Administration researchers were surprised to discover it’s increased in the atmosphere by 25 percent since 2012. A research letter published Wednesday in the journal Nature takes a look at the possible causes for the spike.

“I’ve been making these measurements for more than 30 years, and this is the most surprising thing I’ve seen,” the paper’s lead author, Stephen Montzka, told The Washington Post’s Chris Mooney.

The 1987 Montreal Protocol phased out ozone-damaging chemicals like CFC-11 worldwide. And thanks to the agreement, we’ve avoided a total ozone layer collapse by mid-century. 

Almost no CFC-11 has been been produced since 2006 — or so we thought. The study’s results suggest that someone’s breaking the rules of the agreement. Researchers suspect the spike in the ozone damaging chemical is coming from somewhere in eastern Asia. 

The ultimate impact on the ozone depends on how quickly the culprit is found and stopped. The Guardian reports that if these emissions are left unchecked, it could tack an extra decade onto restoration of the all-important ozone layer, which protects the earth from the sun’s damaging UV radiation.

7 Sneaky Plastic Items to Stop Using

This Earth Day, reducing our plastic consumption is a huge step we can take toward making the planet a better place?and this huge step is actually comprised of several itty, bitty steps! Addressing this part of our lives doesn?t mean we have to immediately and completely shun plastic in all its forms (although, if you?d like to go cold turkey, have at it!).

By being more aware of the everyday situations wherein plastic can sneak into our lives, we can opt to be better prepared and to ultimately reduce how much plastic creation we are supporting.

1. Produce bags

These have an easy way of sneaking their way into our lives while grocery shopping. Even if we commit to not using them for firm fruits and veggies, it is hard to resist a plastic casing for delicate herbs and greens. However, arming ourselves with reusable (and washable) cotton or mesh bags for this purpose is a great step toward never having to use those wasteful plastic bags again.

2. Straws

The sneakiest! They show up in our restaurant and bar drinks without having to ask. Yet, remembering to ask for ?no straw, please? can be quickly learned. If you still like the feel of sipping through a straw, several glass and stainless steel versions exist (some with their own cloth bags for portability).

3. Items that could be purchased in bulk

Hungry for pistachios? Need some pine nuts for a new recipe? Most of these items (and more) can be found in bulk at health food stores and, more often nowadays, more mainstream grocers, as well. Bringing a cloth or mesh bag for nuts and grains (and then transferring to glassware at home) and even glassware for items like nut butters, maple syrup and olive oil (have an associate weigh your container first) are great Earth-friendly ways to reduce plastic waste and the demand for more plastic creation.

4. Bottles of water

It cannot be said enough: always have a water bottle with you! This will reduce temptation to buy water bottles or accept offers for one (?No thank you, I have my water bottle?).

5. Snack bags

Instead of storing snacks (or fridge leftovers) in little plastic bags that will probably be thrown away after one use, invest in some quality reusable packaging: cloth wraps, glassware, stainless steel boxes, etc.

6. Plastic tampon applicators

The only item on this list I?m sure is only used once and definitely thrown away, instead of recycled. Instead of relying on these, consider investing in a menstrual cup that can be used for years – less waste, less hassle and less moments of panic when you realize you don?t have any tampons on hand. If that doesn?t float your boat, several companies are now creating panties that absorb menstrual blood so tampons needn?t enter the equation.

7. Gifts from others

Surprises are wonderful, as are gifts from loved ones. Yet, those who may not be aware of our mission to make the world a plastic-free place may provide gifts chock full of the stuff. As meaningful dates approach, you can gently let your loved ones know that you would greatly appreciate spending time together to make new memories and, oh, by the way, you?re working on reducing your plastic consumption so there?s no need to gift anything with plastic ingredients.

7 Reusable Alternatives to Single-Use Plastic

A brief history of the invention of plastics takes us all the way back to 1839, when a fellow by the name of Eduard Simon inadvertently discovered polystyrene. In 1909 Leo Hendrik Baekeland invented the first synthetic plastic.

Fast-forward to 2017 and a study released by Science Advances tallies up all the plastic ever made. It turns out humans have produced 8.3 billion metric tons of plastic since 1950.

If it was at least being put to good use, that number might not be quite so disturbing. Unfortunately, most plastic production is for single-use packaging.

To put it in perspective, in 2015 humans threw out 141 million metric tons of single-use plastic packaging – almost as much as was made that year.

The amount of plastic trash littering the earth is staggering. Stopping production of this environmentally-unfriendly substance isn?t going to happen, so the next best thing is to vote with your wallet and?choose reusable alternatives to single-use plastic.

1. Plastic Straws

Straw pollution is a huge problem. Edible straws?are one solution, but what if your local smoothie bar doesn?t stock the Lolistraw?

From steel and bamboo to glass and paper, there are plenty of eco-friendly alternatives to plastic straws. You could even go rogue and opt for no straw. You rebel, you.

2. Water Bottles

There are plenty of easy hacks to reduce your plastic consumption and one of them is to get yourself a reusable water bottle. Unlike its single-use plastic cousin, the forever alternative isn?t bad for your health.

3. Plastic Shopping Bags

It?s heartening to see the growing number of countries that have banned plastic bags.

Some, like South Africa, have imposed a tax as a way to discourage people from using them. The amount is far from prohibitive, but at least the major grocery chains have made reusable shopping bags cost-effective and easily available.

4. Take-Out Eating Utensils

Living sustainably isn?t just the domain of the eco-friendly nomad. There?s nothing wrong with carrying a reusable cutlery set with you even if you do have a permanent address. What if you forget your packed lunch or need to work late and order take-out?

5. Take-Out Coffee Cups

Along with plastic straws and water bottles, one of the easiest ways to avoid adding to the world?s growing trash problem is to quit?your morning cappuccino?habit.

I?m kidding. Everyone knows the day hasn?t started until the caffeine?s been had. Just get yourself a reusable coffee cup and you?re good to go.

6. Flip-Flops

Synonymous with summer and lazy days at the beach, the trusty flip-flop is a favorite with many people. They also pose a huge hazard to ocean life.

A better idea is to find an eco-friendly sandal that will last you more than one season.

7. Kids Toys

Although technically not single-use, the cheap gimmicky toys that come in Happy Meals (or lure little hands in the checkout aisle) might just as well be. Kids will whine like there?s no tomorrow until they get it and then toss it aside an hour later. Instead, buy them some?eco-friendly toys they?ll actually appreciate.

If you want to take another step to fight single-use plastic, sign this Care2 petition asking Starbucks to?ditch plastic straws.

7 Green Wedding Favors Your Guests Will Love

Shares

By Marissa Hermanson

Weddings are beautiful events, but they aren’t always environmentally friendly — just think about all those little details from paper invitations to gas-guzzling transportation. However, by planning ahead, you and your beau can help ensure that your nuptial celebration is eco-friendly.

The type of wedding favor you give guests might seem a minor issue — but the wrong choice could result in significant waste. In lieu of wrapped trinkets, show friends and family your gratitude with an environmentally friendly gift. Here are a few ideas for wedding favors that reflect your commitment to sustainability, from fragrant potted herbs to jars of local honey.

1. Potted Plants

A gift that lasts beyond the honeymoon, potted plants are a thoughtful and environmentally friendly favor for your wedding guests. Head to your local garden store and buy plants in bulk that you can pot at home. If you want to give a low-maintenance plant, succulents are a great option. Or consider fragrant herbs that your guests can use for cooking and garnishing. You might want to dress up the plants by decorating the pot with your names and wedding date.

Low-maintenance succulents make attractive wedding favors.

2. Seed Packets or Bulbs

For out-of-town guests, opt for seed packets or flower bulbs that friends and family can easily transport home. If you’re a dahlia enthusiast and the flower is making an appearance at your wedding, order a variety of dahlia bulbs. Alternately, packets of wildflower seeds are a fun gift for guests who have property where they can sprinkle the seeds. Just be sure not to distribute an invasive species. (Also, keep in mind that international guests may not be able to transport seeds or bulbs through customs.)

3. Charity Donation + Seed Paper

For the activist couple, donate money to your favorite local nonprofit or environmental cause on behalf of each guest. To make the gift more personal, write a brief note that explains why you selected the organization(s) for your charitable donation. Print the note (with plant-based ink, if possible) on environmentally friendly seed papers that guests can take home and plant later.

4. Edible Treats

Fill Mason jars or recyclable packages with yummy treats for guests to take home. Bake a batch of cookies, harvest local honey or buy fair-trade coffee from your favorite coffee shop. Your guests can savor these treats at home while they remember your special day.

5. Floral Centerpieces

Floral centerpieces can double as favors. For long tables, consider arranging tall, dramatic orchids down the center; for round tables, cluster potted perennials, greenery or lucky bamboo cuttings. Rather than purchasing new vases or pots, buy them used from local thrift stores. Make sure each table has enough plants for each guest to take one home at the end of your celebration.

6. Double-Duty Glassware

Consider using items at your reception that guests can take home. For instance, budget-friendly Mason jars printed with your wedding date can be used to serve drinks (and eliminate disposable cups). Guests can keep their jars as favors and reuse them at home.

7. No Favors

More and more couples are shying away from wedding favors because they’re costly and can have a negative impact on the environment. If you’re providing food, drink and entertainment, there’s no need to feel guilty about forgoing favors for guests to take home.

When it comes to planning a green wedding, favors are an easy place to start. Your eco-friendly approach to choosing wedding favors may help inspire other decisions you make throughout your planning process, resulting in a celebration that’s as beautiful as it is sustainable.

Did you have a green wedding? What favors did you give your guests? Let us know in the comments.

Climate science’s official text is outdated. Here’s what it’s missing.

The first-ever courtroom tutorial of climate science this week went about as you’d expect. The scientists representing Oakland and San Francisco had Powerpoint problems, and the oil industry’s lawyer cherry-picked his facts.

For all their differences, both sides drew from a common source: The Intergovernmental Panel on Climate Change is the gold-standard for mainstream climate science. Problem is, the last IPCC report came out way back in 2013. As it turns out, we’ve learned a lot about our climate since then, and most of that new information paints an increasingly urgent picture of the need to slash fossil-fuel emissions as soon as possible.

It’s convenient that Chevron’s attorney relied on that aging five-year-old report. The next IPCC report isn’t planned for public release until the fall of 2019. Gathering consensus takes time, and the result is that IPCC reports are out of date before they’re published and necessarily conservative.

The climate models used in these reports grow old in a hurry. Since the 1970s, they’ve routinely underestimated the rate of global warming. Some of the most recent comprehensive assessments of climate science, including last year’s congressionally-mandated, White House-approved, Climate Science Special Report, include scary new sections on “climate surprises” like simultaneous droughts and hurricanes, that have wide-reaching consequences. The scientists representing the two cities knew this, and didn’t limit their talking points to the IPCC.

“Positive feedbacks (self-reinforcing cycles) within the climate system have the potential to accelerate human-induced climate change,” says a section from that Climate Science Special report, “and even shift the Earth’s climate system, in part or in whole, into new states that are very different from those experienced in the recent past.” None of this was included in the last IPCC report.

Actually, a helluva lot has changed in our understanding of the Earth’s climate system since the 2013 IPCC report. Here are some of the highlights:

  1. Sea-level rise is going to be much worse than we thought. Like, potentially a lot worse. In the last IPCC assessment, the worst case scenario for sea-level rise this century was about three feet. That’s now about the midpoint of what’s expected; the worst-case has ballooned to about eight feet. That’s largely because …
  1. Antarctica’s massive ice sheets could collapse much more quickly than we thought. Newly discovered mechanisms of collapse in some of the planet’s largest and most vulnerable glaciers in the West Antarctic Ice Sheet are beginning to capture the attention of the scientific community. Should these mechanisms kick in over the next few decades, they’d unleash enough meltwater to flood every coastal city on Earth.
  1. Extreme weather is here and can now be linked to climate change in real time. From the Arctic to the tropics, wildfires, intense storms and other extreme weather events have been increasingly fierce in recent years, and climate change has played a measurable role. A 2016 report from the National Academies of Sciences opened the floodgates, so to speak, of the burgeoning field of extreme weather attribution. From last year’s Hurricane Harvey to last month’s nor’easter-linked floods in Massachusetts, nearly every weather event now bares a traceable connection to human-caused climate change.
  1. Global warming of 1.5 degrees Celsius is pretty much locked in. A forthcoming special report of the IPCC will say that meeting the 1.5 degree target — one of the most ambitious commitments of the Paris Agreement — looks “extremely unlikely.” Humanity’s shift to zero-carbon energy sources is moving about 10 times too slowly. At this point, it would probably take geoengineering to prevent it. Researchers have started testing ways to do that.
  1. We’ve already lost entire ecosystems, most notably coral reefs. During a record-breaking El Niño event in 2015, the world lost massive swaths of coral in a global bleaching event “unlike anything we’ve ever seen before.” More than 90 percent of the world’s coral will surely die by 2050 without rapid emissions reductions. That means one of the richest stores of biodiversity on the planet is already in jeopardy.

The climate system is moving much more quickly than we thought, and human action to curb climate change is moving much too slowly. Nasty surprises are increasingly possible, and hopeful surprises are more necessary than ever. But there’s some solace to take from this week’s events. The hearing this week is just one of the many courtrooms in which Big Oil has been forced to defend itself. Challenging polluters directly through the courts might result in one of those hopeful surprises people weren’t betting on five years ago.

A federal judge has climate science questions. Here are the answers.

Today’s courtroom drama unfolding in San Francisco will come in the form of a “tutorial” on climate science, not a debate.

Federal Judge William Alsup, a quirky, inquisitive man who previously taught himself the Java programming language for a 2012 lawsuit involving Oracle and Google, will be the only one asking questions. There will be no direct debate between lawyers representing the people of the State of California and those for the defendant oil companies.

In a court document, Judge Alsup narrowed his focus to eight specific questions regarding climate science (in bold below). In the two weeks since the questions were posted, climate scientists have attempted to crowdsource the best, most succinct answers. (I’ve further summed them up in just a few words, in parenthesis.):

  1. What caused the various ice ages (including the “little ice age” and prolonged cool periods) and what caused the ice to melt? When they melted, by how much did sea level rise? (Natural changes in the Earth’s orbit and the amount of greenhouse gases. Sea level rose a lot — more than 400 feet.)
  2. What is the molecular difference by which CO2 absorbs infrared radiation but oxygen and nitrogen do not? (Three-atom molecules vibrate more easily than two-atom molecules.)
  3. What is the mechanism by which infrared radiation trapped by CO2 in the atmosphere is turned into heat and finds its way back to sea level? (Greenhouse gases like CO2 emit extra trapped energy from the sun, warming the surface.)
  4. Does CO2 in the atmosphere reflect any sunlight back into space such that the reflected sunlight never penetrates the atmosphere in the first place? (Yes, but not enough to matter.)
  5. Apart from CO2, what happens to the collective heat from tail pipe exhausts, engine radiators, and all other heat from combustion of fossil fuels? How, if at all, does this collective heat contribute to warming of the atmosphere? (The amount of heat from the sun that’s trapped by greenhouse gases is 100 times more than direct heat from fossil fuel burning.)
  6. In grade school, many of us were taught that humans exhale CO2 but plants absorb CO2 and return oxygen to the air (keeping the carbon for fiber). Is this still valid? If so, why hasn’t plant life turned the higher levels of CO2 back into oxygen? Given the increase in human population on Earth (four billion), is human respiration a contributing factor to the buildup of CO2? (Yes, this is still valid – but this process is roughly carbon neutral, so there is no major impact on the climate. And human respiration of CO2 is 10,000 times too small to matter to the climate.)
  7. What are the main sources of CO2 that account for the incremental buildup of CO2in the atmosphere? (Fossil fuel burning and deforestation)
  8. What are the main sources of heat that account for the incremental rise in temperature on Earth? (Human activities are likely responsible for 93 to 123 percent of recent global warming. It can go over 100 percent because we’re canceling out what would be natural cooling.)

The crowd-sourcing effort (with references) was coordinated by NASA’s Gavin Schmidt, who in an email to Grist said he doesn’t actually expect there to be much disagreement over the science in today’s courtroom tutorial. Chevron, one of the defendants, is not planning to deny evidence at all in its explanations. In fact will refer Judge Alsup to the Intergovernmental Panel on Climate Change — the gold standard of mainstream climate science.

“Despite the attempted interventions from the fringe,” Schmidt wrote, “ I doubt that the defendants or plaintiffs will be making much hay with the science.”

Even if disagreement is unlikely, Andrew Dessler, a climate scientist from Texas A&M University — who penned a Twitter thread of answers to Alsup’s questions — hailed the uniqueness of today’s court activities.

“Obviously, I wish these issues were not still being debated in court, since they’re not being debated in the scientific community, but I also appreciate the deliberate approach the judge seems to be taking,” he wrote to Grist.

No matter what the oil industry lawyers argue today, these facts are well established: Human activities are by far the dominant cause of modern climate change, and only a sharp reduction in our emissions — which means our use of oil — will help solve the problem.

Study: Pride Motivates Better Than Guilt for Green Choices

Shares

A little shaming might seem like a good idea when you see someone skip the recycle bin and head straight for the trash, but you might want to reconsider that approach. A recent study from Princeton University finds that highlighting the pride people will feel if they take environmentally friendly actions may be a better way to change behavior.

Published in the journal PLOS ONE, “The Influence of Anticipated Pride and Guilt on Pro-Environmental Decision Making” asked people from a sample of nearly 1,000 diverse participants to think about either the pride they would feel after taking pro-environmental actions or the guilt they would feel for not doing so, just before making a series of decisions related to the environment. There were various ways to remind them of the pride or guilt they might feel, including a one-sentence reminder that remained at the top of the screen for some participants.

To look at what’s a better motivator, the respondents were asked to make five sets of choices, each with “green” (environmentally friendly) or “brown” (environmentally unfriendly) options. In one scenario, they could choose a sofa made from eco-friendly fabric but available only in outdated styles, or they could pick a more modern style of sofa made from fabric produced with harsh chemicals. In another example, they could pick any or all of 14 green amenities for an apartment, with the caveat that each one added $3 per month to the rent.

Across all the groups — those being reminded to feel pride for making eco-choices, those being reminded to feel guilt for non-eco-choices, and a control group — a pattern emerged. “Overall, participants who were exposed to anticipation of pride consistently reported higher pro-environmental intentions than those exposed to anticipated guilt,” said study author Elke U. Weber.

Why? Some people get defensive when they’re told they should feel guilty about something, which makes them less likely to want to comply with the requested course of action. Those well-intentioned but guilt-based environmental appeals may very well backfire.

So instead of warning people that they’re hastening climate change that will ruin the earth for generations to come, try patting them on the back when you see them make a good decision. Mother Earth will thank you for your kinder, gentler approach.
