<p>The move has been called an implicit “<a href=”https://www.ecowatch.com/trump-worst-president-environment-2645034831.html” target=”_self”>license to pollute</a>,” according to <a href=”https://thehill.com/policy/energy-environment/497630-9-states-sue-epa-for-suspending-pollution-monitoring-requirements” target=”_blank”>The Hill</a>, and allegedly violates numerous federal pollution laws as well as the EPA’s duty to protect the environment.</p><p>The states’ <a href=”https://oag.ca.gov/system/files/attachments/press-docs/New%20York%20v.%20EPA%20Complaint.Filed_.pdf” target=”_blank”>complaint</a> challenges a <a href=”https://www.epa.gov/sites/production/files/2020-03/documents/oecamemooncovid19implications.pdf” target=”_blank”>March 26 EPA memo</a> in which the agency put forth a new, relaxed policy. Polluters are allowed, at their sole discretion, to stop monitoring and reporting <a href=”http://www.ecowatch.com/tag/air-pollution”>air emissions</a> and water pollution levels during the outbreak.</p><p>The memo was produced by the EPA’s compliance director, Susan Parker Bodine, three days after she received a request from the American Petroleum Institute to halt pollution enforcement, reported the <a href=”https://www.sfchronicle.com/environment/article/California-sues-EPA-for-suspending-pollution-15268344.php#photo-18445984″ target=”_blank”>San Francisco Chronicle</a>.</p>

<p>In the <a href=”https://www.epa.gov/sites/production/files/2020-03/documents/oecamemooncovid19implications.pdf” target=”_blank”>memo</a>, Bodine announced that the new, relaxed policies would be retroactive to March 13, when <a href=”https://www.ecowatch.com/tag/donald-trump” target=”_self”>President Trump</a> declared a state of emergency regarding COVID-19. Due to outbreak-related “potential worker shortages” and “travel and social distancing restrictions,” companies could decide for themselves when it would no longer be practical to monitor pollution and report it to federal, state and local agencies, the <a href=”https://www.sfchronicle.com/environment/article/California-sues-EPA-for-suspending-pollution-15268344.php#photo-18445984″ target=”_blank”>San Francisco Chronicle</a> reported.</p><p>Bodine said businesses should try to follow reporting and monitoring regulations but that noncompliance would not be penalized if caused by coronavirus, reported the San Francisco Chronicle. She did not indicate how the EPA could learn of any violations or dangerous emissions if reporting isn’t required, the news report added.</p>

<p>Similarly, the regulation change is “temporary,” but no end date is indicated in the memo. And, while companies are required to document their noncompliance, critics fear the environmental damage will already be done, reported <a href=”https://thehill.com/policy/energy-environment/497630-9-states-sue-epa-for-suspending-pollution-monitoring-requirements” target=”_blank”>The Hill</a>.</p><p>EPA Administrator Andrew Wheeler said that the EPA recognized that challenges created by COVID-19 “may directly impact the ability of regulated facilities to meet all federal regulatory requirements,” reported the <a href=”https://www.sfchronicle.com/environment/article/California-sues-EPA-for-suspending-pollution-15268344.php#photo-18445984″ target=”_blank”>San Francisco Chronicle</a>.</p><p>Wheeler also said the agency would still “expect facilities to comply with their obligations under the law” unless, of course, Covid-19 made it “impracticable,” reported <a href=”https://news.bloomberglaw.com/environment-and-energy/states-sue-trumps-epa-over-rule-relaxation-during-pandemic-1″ target=”_blank”>Bloomberg Law</a>.</p>

<p>The states’ <a href=”https://oag.ca.gov/system/files/attachments/press-docs/New%20York%20v.%20EPA%20Complaint.Filed_.pdf” target=”_blank”>lawsuit</a>, filed in New York federal court, alleges that the EPA lacks the legal authority to “effectively waive critical monitoring and reporting obligations” that alert the public to environmental and health hazards, reported <a href=”https://news.bloomberglaw.com/environment-and-energy/states-sue-trumps-epa-over-rule-relaxation-during-pandemic-1″ target=”_blank”>Bloomberg Law</a>. It also argues that the EPA failed to properly weigh the public health impacts the relaxed policy will have amid the coronavirus pandemic, reported <a href=”https://www.reuters.com/article/us-health-coronavirus-epa/nine-u-s-states-sue-epa-for-easing-environmental-enforcement-amid-pandemic-idUSKBN22P36U” target=”_blank”>Reuters</a>.</p><p>”Rather than exercising enforcement discretion as authorized by law, EPA issued a broad, open-ended policy that gives regulated parties free rein to self-determine when compliance with federal environmental laws is not practical because of Covid-19,” the <a href=”https://oag.ca.gov/system/files/attachments/press-docs/New%20York%20v.%20EPA%20Complaint.Filed_.pdf” target=”_blank”>complaint</a> stated.</p><p>The enforcement suspensions will lead to more chemical spills and “likely will result in increased air and water pollution,” endangering residents who live nearby, downwind or downstream, the suit added, reported the <a href=”https://www.sfchronicle.com/environment/article/California-sues-EPA-for-suspending-pollution-15268344.php#photo-18445984″ target=”_blank”>San Francisco Chronicle</a>.</p>

<p>The states also argued that the EPA failed to demonstrate both the need for the drastic change and any rationale for bypassing the traditional notice and comment period required for new rules, reported <a href=”https://thehill.com/policy/energy-environment/497630-9-states-sue-epa-for-suspending-pollution-monitoring-requirements” target=”_blank”>The Hill</a>. The Clean Air Act and Clean Water Act both require companies to monitor and report emissions to the EPA, and the agency has therefore exceeded its authorities under both regulations, the complaint says, reported The Hill.</p><p>”The Trump Administration cannot give industries the green light to ignore critical environmental and public health laws, especially during a public health crisis,” said New York Attorney General Letitia James, reported <a href=”https://news.bloomberglaw.com/environment-and-energy/states-sue-trumps-epa-over-rule-relaxation-during-pandemic-1″ target=”_blank”>Bloomberg Law</a>.</p><p>California Attorney General Xavier Becerra said, “The Trump Administration is trying to use the current public health crisis to sweep environmental violations under the rug,” reported <a href=”https://thehill.com/policy/energy-environment/497630-9-states-sue-epa-for-suspending-pollution-monitoring-requirements” target=”_blank”>The Hill</a>.</p><p>”What’s worse, the Administration is doing so even as evidence grows that communities exposed to air pollution are at increased risk from coronavirus,” he added, reported The Hill.</p><p>The EPA would not comment on the litigation, but told The Hill that “the EPA temporary policy is a lawful and proper exercise of the Agency’s authority under extraordinary circumstances.” In the same statement, the EPA noted, “This is not a nationwide waiver of environmental rules.”</p>

<p>The EPA was also sued on April 16 by environmental groups seeking to require the agency to determine when companies stopped complying with environmental laws and to immediately notify the public, reported the <a href=”https://www.sfchronicle.com/environment/article/California-sues-EPA-for-suspending-pollution-15268344.php#photo-18445984″ target=”_blank”>San Francisco Chronicle</a>.</p><p>The nine states filing the complaint are California, Illinois, Maryland, Michigan, Minnesota, New York, Oregon, Vermont and Virginia. The suit alleges that the regulation rollback, if allowed to persist, will force states to try to “fill EPA’s enforcement shoes at a time when they are increasingly strapped for resources, or risk the health of our residents,” reported the <a href=”https://www.sfchronicle.com/environment/article/California-sues-EPA-for-suspending-pollution-15268344.php#photo-18445984″ target=”_blank”>San Francisco Chronicle</a>.</p>

What a dinosaur's last supper reveals about life in the Cretaceous period – CBC.ca

Published

on


A beautifully preserved armoured dinosaur found in an Alberta oilsands mine died on a full stomach. The “extraordinarily rare” preservation of its last meal offers new clues and surprises about how the dinosaur lived during its last days.

The 5.5-metre-long, 1,300 kilogram spiky, plant-eating nodosaur, similar to an ankylosaurus but without a tail club, is the only known one of its species, Borealopelta markmitchelli. (Its name means “shield of the north” and honours Mark Mitchell, the technician who spent 7,000 carefully extracting the fossil from the surrounding rock). 

Victoria Arbour, an evolutionary paleontologist at the Royal BC Museum, describes how some armoured dinosaurs likely used their horns, spines and armour for fighting each other, not just for protection. 1:34

The nodosaur lived 110 million years ago during the early Cretaceous, in a lush forest of conifers, ferns and palm-like plants called cycads, near the coast of what was then an inland sea. At the time, the climate was warmer, similar to that of South Carolina, said Caleb Brown, a paleontologist at the Royal Tyrrell Museum of Paleontology in Alberta and lead author of the new study. It was published this week in the journal Royal Society Open Science.

The fossil was discovered by accident in 2011 by Shawn Funk, a shovel operator at the Suncor Millennium Mine near Fort McMurray. Paleontologists from the Royal Tyrrell were called to have a look and realized at once that it was no ordinary fossil.

While most fossils include only bones, this one included skin. It was so well-preserved that it has been described as “mummified.”

In the dinosaur’s belly, “there were these massive concentrations of what looked like rocks,” Brown said.

Those were in a mass about the size of a soccer ball, and it appears they were gastroliths — rocks that some plant-eating dinosaurs use to grind up their food in their stomachs, as modern birds do, instead of using their teeth.

Sure enough, when chunks of the mass were encased in resin, sliced and examined under the microscope, the researcher could see well-preserved twigs, leaves, mosses, pollen and spores.

To get some help at identifying the plant material, the dinosaur researchers turned to paleobotanists, including University of Brandon researcher David Greenwood and his team, along with their retired Royal Tyrrell colleague Dennis Braman.

Ferns and charcoal

They discovered that the dinosaur was a bit of a picky eater. While it lumbered through a landscape that was lush with conifers, horsetails and cycads, there weren’t a lot of those in its stomach.

“It’s almost all ferns,” Brown said, noting that ferns aren’t actually very nutritious. “It wasn’t just hoovering up everything on the landscape.”

But to him, the biggest surprise was that the stomach also contained a significant amount of wood, mostly charcoal, suggesting it was feeding in an area that had recently been ravaged by wildfires.

“And that’s a really cool result,” Brown said. “Because if you look at large mammals that are herbivores today, they often seek out areas that are recovering from forest fires.”

That’s because the new growth tends to be lush, more nutritious than older plants, and low to the ground where it’s easily accessible.

Microscope images show some of the plant material found inside the stomach, including a club moss spore sac (a), fern spore sacs (b-d), a charcoal fragment (e), parts of plant stems and leaves (f-l) and a cross section of a twig, showing its annual rings (m). (Brown et al/Royal Tyrrell Museum)

Forensic paleobotany

By looking at the types of spores and the fact that the twigs appeared to be in the middle of their growing season, the researchers figured out that the animal died during the wet season, which was late spring or early summer.

In Dinosaur Cold Case, a recent documentary about the fossil on CBC’s Nature of Things, Greenwood said extreme storms and flash floods would have been a problem at that time of year on the coastal plain where the dinosaur and suggested that being swept away by rushing water may have been what caused its death.

These are some plant fossils from Alberta from about the time that Borealopelta lived, including ferns, a gingko (d), horsetails (i) and a conifer cone (j). (Brown et al/Royal Tyrrell Museum)

The discoveries about the nodosaur’s last meal are significant because to date, Brown said, “we know almost nothing about what herbivorous dinosaurs eat.”

Only guesses can be made based on what plants lived nearby and the dinosaur’s teeth. There are also clues in fossil dinosaur feces, but the plant material in those are often digested beyond recognition and it’s difficult to know which dinosaur they came from.

Part of the problem is that finding preserved stomach contents from a dinosaur is “extraordinarily rare,” Jim Basinger of the University of Saskatchewan, a co-author of the study, said in a statement. 

Nine cases of possible dinosaur stomachs of plant-eating dinosaurs have been found, the researchers note, but most have turned out to just be plant material found nearby rather than actual stomachs. In this case, the dinosaur was washed far out to sea, without any plants from the landscape it lived in, before it was fossilized.

“So in this case we have what I would say is by far the best evidence that these are stomach contents,” Brown said.

That said, he notes that it may not necessarily be representative of what this species normally ate, as an animal’s diet can vary depending on its age, its health, and the seasonal availability of different foods.

Still, he said it’s useful to be able to compare it to what scientists think plant-eating dinosaurs were eating at that time and raises new questions to investigate, such as: How much of this food a dinosaur this size would have needed to eat to sustain itself? And how did it digest it?

 “I think give us a benchmark for figuring out how this animal may have lived.”

‘Strawberry Moon’ to rise with a special eclipse for some skywatchers – Globalnews.ca

Published

on


The full moon on Friday, June 5 might look a little different in some parts of the world, where the so-called “Strawberry Moon” will fall partially under the Earth’s shadow.

The phenomenon, known as a penumbral lunar eclipse, occurs when the Earth comes between the sun and the moon, thereby casting a faint shadow on the moon. This penumbral lunar eclipse will make the full moon look slightly darker on part of its surface, although only some portions of the world will see it.

The penumbral lunar eclipse will only be visible from parts of Australia, Asia, Africa, Europe and South America, according to NASA’s charts.

In other words, North Americans will need to watch a livestream on the internet to catch a glimpse of the event, which starts at 3 p.m. EDT. Nevertheless, the so-called “Strawberry Moon” will be visible to everyone.

That name comes from the time of year and not the expected colour of the moon. There are farm-related nicknames for the first full moon of every month, and the strawberry nickname originated from the Algonquin First Nation, according to the Old Farmer’s Almanac. The first full moon of June often coincided with the harvest season for wild strawberries in North America, the Almanac says.

Although skywatchers in Canada and the U.S. will miss out on this penumbral lunar eclipse, they’ll only have to wait a month to catch the next one. Another penumbral lunar eclipse is slated to happen on July 5, and that one should be visible from North America. The darkest penumbral lunar eclipse of the year is expected on Nov. 30.

A penumbral lunar eclipse also happened on Jan. 10, coinciding with that month’s “Wolf Moon.”

Not to throw shade at the penumbral lunar eclipses, but they’ll likely pale in comparison to the annular solar eclipse predicted for June 21. That’s when the moon will pass between the Earth and the sun, making the sun look like a ring of fire for viewers in parts of Africa, China, northern India and Pakistan, according to TimeandDate.com.

Again, it won’t be visible from North America — but you’ll still be able to watch the whole thing online without risking eye damage from staring at the sun.

In Space No One Can Hear You Campaign: Trump Team Pulls Ad – NDTV

Published

on


Donald Trump’s re-election campaign has pulled a video featuring the SpaceX launch and astronauts

Washington:

President Donald Trump’s re-election campaign has pulled a video featuring the SpaceX launch and astronauts which appeared to violate NASA’s media regulations, reports said.

The “Make Space Great Again” YouTube ad posted on YouTube showed footage from the Apollo program, as well as video of the landmark SpaceX Demo-2 mission and NASA astronauts Bob Behnken and Doug Hurley, the SpaceNews.com website said.

YouTube shows the video was removed by the uploader.

NASA generally allows use of its images and video but prohibits the use of its insignia and photographs of its astronauts in advertisements.

“As a government agency, NASA will not promote or endorse or appear to promote or endorse a commercial product, service or activity. Therefore, there are strict limits placed on the use of any of the NASA identities and emblem imagery in advertisements,” the space agency’s advertising regulations say.

“Astronauts or employees who are currently employed by NASA cannot have their names, likenesses or other personality traits displayed in any advertisements or marketing material.”

Hurley’s wife Karen Nyberg, a retired astronaut, and their young son were also reportedly shown in the clip.

“I find it disturbing that a video image of me and my son is being used in political propaganda without my knowledge or consent. That is wrong,” Nyberg tweeted.

A Change.org petition to “Stop Donald Trump politicizing SpaceX and NASA accomplishments” has attracted more than 6,000 signatures so far.

The New York Times described the video as “the latest effort by the president to parlay his stewardship of American space policy into an upbeat campaign issue.”

The SpaceX mission, which blasted off from Florida’s Kennedy Space Center on May 30, was the first crewed US spacecraft in nearly a decade.

Trump, who witnessed the liftoff, has relaunched the race to re-conquer the Moon and to journey onwards to the Red Planet.

But the deadlines — 2024 and 2033 respectively — appear unrealistic and have caused turbulence within the space agency.
