Does fighting climate change mean wrecking the economy?

That’s the question my editor posed to me about a year ago. It has been the focus of my reporting ever since.

The rhetoric from climate change skeptics suggests it would. President Donald Trump has made canceling Obama-era greenhouse gas regulations a central part of his tenure. Economic rationales are always front and center.

Meanwhile, Democratic presidential candidates say they will create millions of jobs by transforming the energy system to carbon-free sources.

Job killer or job creator? Leaving aside for the moment the fact that climate change is already imposing enormous costs that are only becoming worse, I went looking for answers in Massachusetts, Wyoming and Colorado.

Here’s some of what I learned. It’s not simple. And much remains to be seen.

1. Where steps have been taken, the economy has kept growing. 

Take Massachusetts, for example. The Bay State passed the Global Warming Solutions Act in 2008, calling for an 80% reduction in greenhouse gases from 1990 levels by 2050. Massachusetts requires power plants to pay for their carbon dioxide emissions. The state was among the first to require power companies to generate a certain portion of their electricity from renewable sources. The government offers rebates and incentives for renewable energy, energy efficiency, electric vehicles and more.

Greenhouse gas emissions have come down by 17% from 2008 to 2017 in the state.

Meanwhile, Massachusetts’ economy has continued to grow. The state’s total output went up by 19% in that period, outperforming U.S. economic expansion as a whole by 3% in that time frame.

Employment went up in Massachusetts by 9%. The state has invested in growing a clean-energy economy. Jobs in renewable energy, energy efficiency and related areas have grown by 86% since 2010 and now make up more than 3% of the state’s workforce.

It’s hard to know, though, to what extent the state’s climate policies were responsible for either the greenhouse gas reductions or economic growth. From 2008 to 2017, carbon emissions went down in every state but six: Idaho, Nebraska, North Dakota, Mississippi, Texas and Washington. GDP shrank in just four states: Connecticut, Louisiana, Nevada and Wyoming.

That’s largely because cutting carbon has become much easier to do with the rise of natural gas and renewable power.

2. Some of the most significant greenhouse gas reductions have happened not because of state policies but because of dramatic shifts in energy markets.

The biggest factor lowering carbon dioxide emissions nationwide is that natural gas has replaced coal as the main fuel for electric power plants.

Burning natural gas generates the same amount of energy with half the carbon dioxide emissions as coal. The price of natural gas has plunged as drilling technology has made the United States the world’s leading producer. That has helped drive a wave of fuel-switching at power plants across the United States. Coal generation fell 40% from 2008 to 2017, while natural gas climbed 47%.

Renewable energy is growing quickly, but it still makes up a small portion of the power supply. Wind generated just 6.5% of the nation’s electricity last year. Solar produced 2.2%.

Wind and solar are starting to give fossil fuels serious competition, though. After dramatic cost declines over the last decade, these sources are now significantly cheaper than coal and often cheaper than natural gas, even without subsidies.

They need to replace fossil fuel generation much faster, however, in order to take a serious bite out of emissions.

3. Some good jobs are going away. Dealing with the changes is not easy.

Powering the nation is not the job it used to be. Coal once generated more than half the nation’s electricity. Coal mines and power plants are mostly unionized. The jobs pay well and provide good benefits for workers without a higher education.

Coal mining, however, employs 42% fewer workers than in 2011. More than 300 coal-burning power plants have closed or are slated to be shuttered.

There are growing opportunities in renewable energy and energy efficiency. The solar industry employed 242,000 people in 2018, for example, about 45,000 more than the coal industry.

The jobs are not equivalent. Many solar installation jobs are not unionized, don’t pay as well and have fewer benefits than those for people working at coal plants. And a solar farm doesn’t need many workers once it’s built, while a coal plant can steadily employ hundreds.

Workers hurt by the energy transition are a small part of the overall economy. But coal mines and power plants tend to be in rural areas without much else in the way of industry. When these jobs go away, the pain is localized but intense.

Some policymakers are trying to blunt the impacts. Last year, Colorado was one of several states that passed laws aimed at cutting greenhouse gas emissions and included provisions for a “just transition” — job retraining, economic development aid and other measures to help workers and communities find a life after fossil fuels.

4.  No one is doing enough. 

The plunge in coal-fired power helped the United States cut its emissions by an estimated 2.1% in 2018. Since 2005, emissions are down 12.3%.

But the United States pledged to cut greenhouse gases at least 26% by 2025 under the U.N. Paris climate agreement. Emissions must go down by 2.8% per year on average to hit that target. It’s not impossible, experts say, but it’s a stretch.

The Trump administration is moving policy in the opposite direction, aiming to weaken fuel economy standards for vehicles, approving construction of a new oil pipeline from Canada and vowing to shore up America’s coal industry.

Meeting the Paris pledge is not enough, however. Scientists say the world needs to get to zero carbon emissions by 2050 to stave off a climate disaster. Almost no one is on track to do so.

Unless cost-effective carbon capture technology appears soon, natural gas will have to go. Transportation, the largest source of U.S. greenhouse gases, will have to go electric (or hydrogen or biofuel) much, much faster than it is. And someone will have to figure out what to do about emissions from energy-intensive industries like glass, steel, aluminum and concrete.

Does fighting climate change mean wrecking the economy? Not necessarily. But the steps taken so far will not stop the climate impacts we’re already seeing from becoming much worse.

Can we stop climate change before it’s too late? No one has all the answers yet.

But something must be done. Each new climate-related disaster shows the cost of inaction is mounting.  (VOA)

New species of crested dinosaur identified in Mexico

Published

 on

A team of palaeontologists in Mexico have identified a new species of dinosaur after finding its 72 million-year-old fossilized remains almost a decade ago, Mexico’s National Institute of Anthropology and History (INAH) said on Thursday.

The new species, named Tlatolophus galorum, was identified as a crested dinosaur after 80% of its skull was recovered, allowing experts to compare it to other dinosaurs of that type, INAH said.

The investigation, which also included specialists from the National Autonomous University of Mexico, began in 2013 with the discovery of an articulated tail in the north-central Mexican state of Coahuila, where other discoveries have been made.

“Once we recovered the tail, we continued digging below where it was located. The surprise was that we began to find bones such as the femur, the scapula and other elements,” said Alejandro Ramírez, a scientist involved in the discovery.

Later, the scientists were able to collect, clean and analyze other bone fragments from the front part of the dinosaur’s body.

The palaeontologists had in their possession the crest of the dinosaur, which was 1.32 meters long, as well as other parts of the skull: lower and upper jaws, palate and even a part known as the neurocranium, where the brain was housed, INAH said.

The Mexican anthropology body also explained the meaning of the name – Tlatolophus galorum – for the new species of dinosaur.

Tlatolophus is a mixture of two words, putting together a term from the indigenous Mexican language of Nahuatl that means “word” with the Greek term meaning “crest”. Galorum refers to the people linked to the research, INAH said.

Alberta family searches for answers in teen's sudden death after COVID exposure, negative tests – CBC.ca

Published

 on


A southern Alberta mother and father are grappling with the sudden, unexplained death of their 17-year-old daughter, and with few answers, they’re left wondering if she could be the province’s youngest victim of COVID-19.

Sarah Strate — a healthy, active Grade 12 student at Magrath High School who loved singing, dancing and being outdoors — died on Monday, less than a week after being notified she’d been exposed to COVID-19.

While two tests came back negative, her parents say other signs point to the coronavirus, and they’re waiting for more answers. 

“It was so fast. It’s all still such a shock,” said Sarah’s mother, Kristine Strate. “She never even coughed. She had a sore throat and her ears were sore for a while, and [she had] swollen neck glands.”

Kristine said Sarah developed mild symptoms shortly after her older sister — who later tested positive for COVID-19 —  visited from Lethbridge, one of Alberta’s current hot spots for the virus.

The family went into isolation at their home in Magrath on Tuesday, April 20. They were swabbed the next day and the results were negative.

‘Everything went south, super-fast’

By Friday night, Sarah had developed fever and chills. On Saturday, she started vomiting and Kristine, a public health nurse, tried to keep her hydrated.

“She woke up feeling a bit more off on Monday morning,” Kristine said. “And everything went south, super-fast.”

Sarah had grown very weak and her parents decided to call 911 when she appeared to become delirious.

“She had her blanket on and I was talking to her and, in an instant, she was unresponsive,” said Kristine, who immediately started performing CPR on her daughter.

When paramedics arrived 20 minutes later, they were able to restore a heartbeat and rushed Sarah to hospital in Lethbridge, where she died.

“I thought there was hope once we got her heart rate back. I really did,” recalled Sarah’s father, Ron.

“He was praying for a miracle, and sometimes miracles don’t come,” said Kristine.

Searching for answers

At the hospital, the family was told Sarah’s lungs were severely infected and that she may have ended up with blood clots in both her heart and lungs, a condition that can be a complication of COVID-19.

But a second test at the hospital came back negative for COVID-19.

“There really is no other answer,” Ron said. “When a healthy 17-year-old girl, who was sitting up in her bed and was able to talk, and within 10 minutes is unconscious on our floor — there was no reason [for it].”

The province currently has no record of any Albertans under the age of 20 who have died of COVID-19.

According to the Strate family, the medical examiner is running additional blood and tissue tests, in an effort to uncover the cause of Sarah’s death.

‘Unusual but not impossible’

University of Alberta infectious disease specialist Dr. Lynora Saxinger, who was not involved in Sarah’s treatment, says it is conceivable that further testing could uncover evidence of a COVID-19 infection, despite two negative test results.

However, she hasn’t seen a similar case in Alberta.

“It would be unusual but not impossible because no test is perfect. We have had cases where an initial test is negative and then if you keep on thinking it’s COVID and you re-test, you then can find COVID,” she said.

According to Saxinger, the rate of false negatives is believed to be very low. But it can happen if there are problems with the testing or specimen collection.

She says people are more likely to test positive after symptoms develop. 

“The best sensitivity of the test is around day four or five of having symptoms,” she said. “So you can miss things if you test very, very early. And with new development of symptoms, it’s always a good time to re-test because then the likelihood of getting a positive test is a little higher. But again, no test is perfect.” 

Sarah deteriorated so quickly — dying five days after she first developed symptoms — she didn’t live long enough to make it to her follow-up COVID-19 test. Instead, it was done at the hospital.

‘An amazing kid’

The Strate family now faces an agonizing wait for answers — one that will likely take months — about what caused Sarah’s death.

But Ron, who teaches at the school where Sarah attended Grade 12, wants his daughter to be remembered for the life she lived, not her death.

Sarah was one of five children. Ron says she was strong, active and vibrant and had plans to become a massage therapist after graduating from high school.

She played several sports and loved to sing and dance as part of a show choir. She was a leader in the school’s suicide prevention group and would stand up for other students who were facing bullying.

“She’s one of the leaders in our Hope Squad … which goes out and helps kids to not be scared,” he father said.

“She’s an amazing kid.”

Sarah would often spend hours helping struggling classmates, and her parents hope her kindness is not forgotten.

“She’d done so many good things. Honestly, I’ve got so many messages from parents saying, ‘You have no idea how much your daughter helped our kid,'” said Ron.

“This 17-year-old girl probably lived more of a life in 17 years than most adults will live in their whole lives. She was so special. I love her so much.”

China launches key module of space station planned for 2022

Published

 on

BEIJING (Reuters) -China launched an unmanned module on Thursday containing what will become living quarters for three crew on a permanent space station that it plans to complete by the end of 2022, state media reported.

The module, named “Tianhe”, or “Harmony of the Heavens”, was launched on the Long March 5B, China’s largest carrier rocket, at 11:23 a.m. (0323 GMT) from the Wenchang Space Launch Centre on the southern island of Hainan.

Tianhe is one of three main components of what would be China’s first self-developed space station, rivalling the only other station in service – the International Space Station (ISS).

The ISS is backed by the United States, Russia, Europe, Japan and Canada. China was barred from participating by the United States.

“(Tianhe) is an important pilot project in the building of a powerful nation in both technology and in space,” state media quoted President Xi Jinping as saying in a congratulatory speech.

Tianhe forms the main living quarters for three crew members in the Chinese space station, which will have a life span of at least 10 years.

The Tianhe launch was the first of 11 missions needed to complete the space station, which will orbit Earth at an altitude of 340 to 450 km (211-280 miles).

In the later missions, China will launch the two other core modules, four manned spacecraft and four cargo spacecraft.

Work on the space station programme began a decade ago with the launch of a space lab Tiangong-1 in 2011, and later, Tiangong-2 in 2016.

Both helped China test the programme’s space rendezvous and docking capabilities.

China aims to become a major space power by 2030. It has ramped up its space programme with visits to the moon, the launch of an uncrewed probe to Mars and the construction of its own space station.

In contrast, the fate of the ageing ISS – in orbit for more than two decades – remains uncertain.

The project is set to expire in 2024, barring funding from its partners. Russia said this month that it would quit the project from 2025.

Russia is deepening ties with China in space as tensions with Washington rise.

Moscow has slammed the U.S.-led Artemis moon exploration programme and instead chosen to join Beijing in setting up a lunar research outpost in the coming years.
