Why New Delhi’s air is always so toxic this time of year

by winonaogden3719 Posted on November 5, 2019

India’s capital city of New Delhi has been making headlines this week for its abysmal air quality as the concentration of particulate matter reached above 400 micrograms per cubic meter, 20 times the levels deemed healthy by the World Health Organization and the worst the city has seen since 2016.

On October 31, the government declared a public health emergency, closing schools, banning construction and fireworks, and limiting private vehicle use to every other day for five days in an effort to protect the population and make a dent in the pollution. Flights have been delayed and hospitals inundated with patients suffering from coughs, dry eyes and throats, and other symptoms brought on or exacerbated by the toxic air.

On the ground, it looks like a scene from a post-apocalyptic movie. Blanketing the streets is smog so dense you can’t see the length of a city block, and the sharp smell of smoke is detectable even through a mask, without which you’d be exposed to air that, over the course of a day, is equivalent to smoking a couple packs of cigarettes.

Unfortunately, this sort of air pollution is nothing new to the residents of Delhi, nor those of many other Indian cities. A study released earlier this year found that 22 of the world’s 30 most polluted cities are in India, and the fall and winter months are always especially toxic.

The stew of pollution choking New Delhi this time of year doesn’t have one single source. Massive clouds of smoke drift south from the neighboring states of Punjab and Haryana, where farmers burn crop stubble from their fields after the harvest to trap nutrients in the soil. Fireworks set off in the streets by the city’s 2 million residents during the Hindu festival of lights, Diwali, don’t help either. And then there are the usual suspects: car and industrial emissions.

But it’s not just human activity that’s to blame — local weather patterns don’t help the problem, either. Cold air settles into the low-lying city, bringing with it, and holding in, pollutants.

The government has been struggling for years — mostly without success — to curb air pollution. Crop burning and firecrackers are both illegal, but people mostly ignore these bans, as well as the efforts to replace the practices with greener alternatives.

Hopefully residents will be breathing easier soon — air quality has begun to improve significantly in the last couple days thanks to winds, the odd-even car scheme, and a reduction in crop burning in Haryana. But these are short-term fixes, and just as history tells us that this year’s emergency-level air pollution wasn’t a fluke, it also suggests that large-scale measures will need to be taken if the people of New Delhi hope to avoid future polluted falls and winters.

11,000 scientists say that the ‘climate emergency’ is here

by ZacheryQVVR Posted on November 5, 2019

More than 11,000 scientists declared a climate emergency today in — where else — an article published in a scientific journal.

“Scientists have a moral obligation to clearly warn humanity of any great existential threat and to ‘tell it like it is,’” begins the “World Scientists’ Warning of a Climate Emergency,” published in BioScience. It continues, “On the basis of this obligation … we declare … clearly and unequivocally, that planet Earth is facing a climate emergency.”

The declaration was co-written by William Ripple, a professor of ecology at Oregon State University and the founder of the environmental advocacy group Alliance of World Scientists, and undersigned by more than 11,000 scientists and climate experts.

These signatories aren’t the first to describe the present state of the climate as a crisis. Hundreds of governments of various sizes around the world, including New York City and the United Kingdom, have passed resolutions saying the same. This summer, some members of Congress proposed a resolution for the U.S. government to join the climate-emergency chorus.

This particular declaration is a little different, though — for one thing, it’s peer reviewed. It’s also the first time so many scientists have directly told the public that the current state of the climate constitutes a crisis, rather than letting their data speak for itself.

“Phrases like ‘climate change’ sound a little bit mild, in terms of how severe the problem is,” Ripple told Grist. “So, we wanted to publish language that is consistent with the data and the trends that we’re seeing.”

Ripple organized a similar initiative back in 2017, when he and 15,000 other scientists issued a “warning to humanity” about climate change (which was itself an homage to a climate warning written by a different group of scientists in 1992). But Ripple decided it was time to upgrade the warning to a declaration of emergency after talking to Representative Earl Blumenauer from Oregon, who introduced the resolution for Congress to declare a national climate emergency back in July.

“In my view, declaring a climate emergency should mostly be based on the data,” said Ripple. “These governmental bodies, they’ll look to the science to see if they are on solid ground before they pass these resolutions.”

Even though outright climate denialism is increasingly illegitimate in mainstream news, the debate over whether to use words like “catastrophe,” “emergency,” or “crisis” continues. So Ripple wanted politicians, activists, and the general public to know that the science supports urgency. He wrote the letter, which details the basic facts of climate change — how human impacts, like CO2 emissions and deforestation, have environmental consequences, like the concentration of greenhouse gases in the atmosphere and global temperature rise — and sent it around to other scientists, who added their names to the message by the thousands.

But what exactly does it mean to declare a climate emergency? Sure, the first step to solving a problem is admitting you have one, and advocates of climate emergency resolutions point out that acknowledging the severity of the problem posed by our warming planet is a prerequisite for action.

It’s easy to look skeptically at climate emergency resolutions, though, since they’re largely symbolic measures at a time when there are so many tangible actions that need to be taken — transitioning the energy sector from fossil fuels to renewable sources, say. Resolutions also usually (although not always) call for vague, nonbinding measures without legal mechanisms to hold governments accountable for meeting them.

Whether or not you think climate emergency resolutions are an effective tactic for inspiring more concrete actions, it’s a pretty big deal that so many scientists have decided it’s necessary to step out of their labs and into the political arena. If you didn’t believe our warming planet is in a state of emergency, just know that several thousand scientists want you to know otherwise.

How To Grow a Clover Lawn To Improve Biodiversity

The American obsession with a pristine, green lawn presents a few problems. That green lawn requires a lot of work to maintain and is a huge drain on resources. Lawns in the U.S. are the country’s largest irrigated crop, consuming more land than any food crop. Besides hogging resources, the solid carpet of turfgrass we’ve created also hurts wildlife by discouraging biodiversity and creating runoff that pollutes waterways.

There are benefits to having a yard full of grass. And it’s possible to have a gorgeous, biodiverse lawn that benefits the environment. It just takes a little rethinking about what makes a lawn, including reconsidering clover — a plant that we redefined as a weed after WWII.

Embracing clover as a mainstay of your lawn can tip the balance back in an eco-friendly direction. You’ll also benefit from a lower-maintenance, self-fertilizing green lawn.

Choosing the Right Clover Strategy

The benefits of clover are vast. It’s drought tolerant and self-fertilizing. The plant absorbs nitrogen from the atmosphere and returns it to the soil. In other words, it creates its own fertilizer and fertilizes nearby plants. When you mix it with common grass types such as Kentucky bluegrass or fescues, it creates enough nitrogen to eliminate the need for chemical fertilizers.

Clover provides forage for pollinators such as bees. It also looks magical and you may find your neighbors admiring it. Just make sure you choose the variety best suited to your needs. Dutch white clover (Trifolium repens) or micro clover (Trifolium repens var. Pipolina) are the best species to incorporate into your turf. Dutch white clover stays green year-round, while micro clover turns brown during the winter. Micro clover is more tolerant of foot traffic and blooms 90 percent less than Dutch white clover. That means fewer bees and less support for pollinators .

Most people are happiest with a combination of turfgrass and clover. While some perform aggressive lawn makeovers to completely convert to clover, that isn’t necessary. If you already have a lawn, you can overseed it with clover and gradually let the clover take over.

Planting Clover

To establish a mixed grass/clover lawn, you can sow clover seed into the lawn, encourage existing clover patches, or both. Encouraging existing patches is as easy as mowing over clover with the mower blade set low, between 1½ and 2 inches. This will allow the clover to take over by weakening the grass.

Sow seed in spring as soon as the last frost has passed. Dutch white clover should be seeded at 1 pound of seed to 1,000 square feet, and micro clover needs double that. After you seed, water the lawn daily until seedlings are visible, and then only once in a while, as needed.

Maintaining a Clover Lawn

There’s no need to fertilize a clover lawn. It takes care of that for you! It is also imperative that you do not apply broadleaf herbicides to a clover lawn unless you want to kill it. Your irrigation bill should drop, as this classic “weed” is drought tolerant. Try irrigating every other week in summer and see how it performs. A bonus? You only have to mow a clover lawn once a month to keep it looking tidy. Other than the frequency, just mow clover the same way you would mow a regular grass lawn.

The very same weeds that homeowners have been struggling to eradicate might be the answer to the low-maintenance, green lawn you dream of. Unlike typical turfgrasses, a clover lawn reduces water use, eliminates the need for fertilizer, cuts time spent on lawn care in half, and increases biodiversity. Plant it right and enjoy a future where your lawn is part of the solution rather than contributing to the lawn problem.

Here’s why Twitter’s political ad ban gives Big Oil a free pass

by BertieA66t Posted on November 4, 2019

If you’re fortunate enough not to have a Twitter account, then you might have missed the news that the website’s CEO, Jack Dorsey, took the unprecedented step of banning political ads last week. In a Twitter thread (what else?), Dorsey explained the logic behind the move, which sets the social network apart from major competitors like Facebook, which has not banned much of anything, including neo-Nazis, in the name of “free speech.” “We believe political message reach should be earned, not bought,” he wrote.

Twitter’s decision, which will take effect on November 22, was hailed as a win for democracy and civic discourse. In a tweet, Representative Alexandria Ocasio-Cortez of New York called the move a “good call,” adding, “if a company cannot or does not wish to run basic fact-checking on paid political advertising, then they should not run paid political ads at all.”

But there’s a significant downside to Twitter’s decision. Ads that “advocate for or against legislative issues of national importance,” like immigration, health care, and, yes, climate change, are on the chopping block. And when it comes to the issue of climate change, Twitter’s new policy gives oil and gas companies a leg up, and the folks who want to regulate those companies a kneecapping.

In recent years, Big Oil has finally wiped the smog off its glasses and read the writing on the wall: the public knows that a shortlist of multinational corporations are responsible for the lion’s share of the world’s planet-heating emissions. So those corporations shifted tactics lickity-split. Instead of denying that climate change exists, fossil fuel companies want you, and government regulators, to think that they’ve changed their oily ways. ExxonMobil says it’s investing heavily in developing a clean biofuel from algae. Shell produced several climate change manifestos with hopeful titles like “the Sky scenario” that it says have the potential to stop climate change. Chevron is saving turtles in the Philippines.

The problem is that these great initiatives are just a tiny sliver of what Big Oil actually does, which is — you guessed it! — dig up and sell oil. Algae biofuel is Exxon’s hobby (read: marketing ploy), oil is its day job. But it wants you, the consumer, to think that its top scientists are in the lab day and night working tirelessly to save the planet. Meanwhile, in Congress, these same companies are spending hundreds of millions every year to lobby against any kind of climate regulation that will hurt their bottom lines.

Twitter’s new policy allows ExxonMobil to keep filling up your newsfeed with ads about a biofuel that isn’t going to be commercially viable for at least another decade. But it bans a politician from buying ad space to tell you that, if elected, they plan to go after Big Oil.

Exxon’s efforts may not appear overtly political, but they absolutely are. Trying to hoodwink voters and regulators so that the government doesn’t hold polluters accountable is fundamentally at odds with Dorsey’s vision of earning reach instead of buying it. Has Big Oil earned the right to clog our newsfeeds with pictures of green gunk that’s ostensibly going to save the earth? Certainly not.

Twitter has put us in a tough spot. Yes, it’s good that, pretty soon, politicians and dark-money-fueled super-PACs won’t be able to force whatever nonsense they want onto the public. But the new ban will also tilt the online playing field in favor of companies that want to keep burning fossil fuels and against the politicians and groups that want to legislate them out of existence. Which is all to say that regulating civic discourse on social media is a gargantuan task and one that’s nearly impossible to do right. If you came here looking for an answer to this ethical dilemma, I’m sorry to disappoint. Go tweet @jack.

Ocean Outbreak

Confronting the Rising Tide of Marine Disease

Drew Harvell

Genre: Environment

Price: $18.99

Publish Date: April 16, 2019

Publisher: University of California Press

Seller: University of California Press


There is a growing crisis in our oceans as rates of infectious disease outbreaks are on the rise. Marine epidemics have the potential to cause a mass die-off of wildlife from the bottom to the top of the food chain, impacting the health of ocean ecosystems as well as lives on land. Fueled by sewage dumping, unregulated aquaculture, and drifting plastic in warming seas, ocean outbreaks are sentinels of impending global environmental disaster.   Ocean Outbreak follows renowned scientist Drew Harvell and her colleagues as they investigate how four iconic marine animals—corals, abalone, salmon, and starfish—have been devastated by disease. Based on over twenty years of research, this firsthand account of the sometimes creeping, sometimes exploding impact of disease on our ocean’s biodiversity ends with a hopeful message. Through policy changes and the implementation of innovative solutions from nature, we can reduce major outbreaks, save some ocean ecosystems, and protect our fragile environment.
