Heat waves to become a common occurrence, experts say

(KRON) – As many people across the Bay Area are dealing with extreme heat, climate specialists said heat waves like this one are going to continue to become more common. 

"We are now in a climate where severe heat is both more intense and record-breaking heat is more frequent than compared to how it used to be decades ago,” said Stanford Doerr School of Sustainability Professor Noah Diffenbaugh.

As extreme heat closes down outdoor spaces and opens up cooling centers, Diffenbaugh said the climate we live in has changed. 

"It really requires an acknowledgement and understanding that we're already in a new climate and that it will continue to intensify as global warming continues in the coming decades,” said Diffenbaugh.

He said the amount of warming we're experiencing is not uniform throughout the year. 

"We've had about 2 degrees Fahrenheit of global warming. But this time of year, that we're in right now where we tend to get some of the hottest days of the year that's actually warming even more rapidly than for the annual warming overall,” added Diffenbaugh.

That is what leads to more wildfires. There is more dried vegetations and more extreme heat this time of year. In the last week, the California legislature passed bills to focus on clean energy, removing carbon from the atmosphere and end new oil drilling near communities. 

While Diffenbaugh said climate change has already happened, these things can make a difference. 

"What we do now will absolutely have benefits both now and in the future. California has been a leader in climate policy both for reducing the trajectory of greenhouse gas emissions as well as to adapting to a changing climate,” said Diffenbaugh.

He said there are still some challenges when it comes to protecting people from dangerous heat and protecting the environment. 

"Going forward in the future is how to provide the benefits of cooling that air conditioning provides without increasing global warming and climate change through increased emissions,” said Diffenbaugh.

He said scientists are still working on solving that problem. During the current Bay Area heat wave, state regulators have urged the public to conserve energy when and where they can.

Start your holiday shopping now or risk items being out of stock, experts say

ST. LOUIS (KTVI) -- Forget December! if you want the most wonderful time of the year to be holly and jolly, you might want to get shopping even while it’s still hot outside.

“As it relates to the holidays, now is the time because all of the things are going to be impacted -- the factories, the warehouses, the trucks," UMSL Professor Mitch Millstein said.

Millstein, who teaches supply chain and analytics at the University of Missouri St. Louis Business School, said nearly a year and a half into the pandemic, companies and consumers are still navigating a changing landscape.

“The disruption that occurred last year is like a wave. We’re in the wave. The wave is going through the supply chain now. I was talking to a vice president of operations just the other day. He’s working in the warehouse because he’s got people out and his warehouse manager is packing orders,” Millstein said.

Whether it’s workers or widgets, the shortages are real and quick solutions aren’t always realistic.

“What happened overseas is containers ended up in the wrong place. This is really a once-in-a-lifetime phenomenon. Because we stopped ordering them or put a stop to the orders, they had to go someplace. They ended up in the wrong place. This is still being sorted out today," Millstein said.

Rod Sides, vice-chair and US leader of retail and distribution for Deloitte, said rising prices are causing concern.

“Consumers are showing us they are worried about inflation and the cost of goods going up,” he said.

He points to back-to-school shopping as an indicator of how the holiday hustle will function.

“Folks moved earlier in the season because they were worried about stockouts. We’re going to see the exact same thing happen with the holiday,” Sides said.

Experts say if you want to make sure your gifts make it under the tree, start your holiday shopping now.

“We’re going to have to think not days ahead, not I’m going to shop on Black Friday for what I want on Christmas because that’s a month ahead of time and I get great details. We’ve got to go a couple of months,” Millstein said.

Pandemic brings surge of eating disorders among young people, experts say

CLEVELAND (WJW) – Health experts at the Cleveland Clinic are worried about another crisis they're saying is being exacerbated by the COVID-19 pandemic – a surge in eating disorders among young people.

"Our numbers have doubled for people who are serious enough that they need acute medical stabilization in the hospital. Our numbers have quadrupled for people coming back with, for outpatient evaluations, new as well as people who have fallen off the recovery wagon," said Dr. Ellen Rome, head of the Center for Adolescent Medicine at Cleveland Clinic Children."

This isn't a problem just relegated to northeast Ohio. Rome says hospital systems across the nation and the world are seeing this doubling, tripling and quadrupling of cases.

"We're seeing all walks of life, all social-economic brackets, male, female, boy, girl, transgender, kids, it's an equal opportunity disease affecting everybody in so many places," Rome said.

She says the disease also runs the age spectrum from geriatric patients, to the very young. 

"My youngest eating disorder patient was five and had been binging and purging since she was 2 and a half," Rome said.

The National Eating Disorders Association reported it saw a more than 58% jump in outreach to its helpline since the pandemic started.

"There's all the regular stressors: isolation, depression, anxiety, and then add to that more time on their phone, more time on their personal enslavement device to have those triggers that social media can exacerbate in respect to body image," Rome said.

Rome said red flags for parents and guardians to look for include not eating with the family or only in their room.

"Other red flags include lightheadedness, dizziness, fainting or change in behaviors, loss of periods [and] dry skin."

There is concern that the growing delta variant could worsen the stress of kids or their parents and increase cases further.

"Anything that worsens the stress of kids or their parents will bring out the disordered eating or other maladaptive coping strategies. We want to make sure that parents know what resources are around, that they seek our help and that we get kids to the right resources early enough so that the behaviors don't get hardwired," Rome said.

Those resources include the National Eating Disorders Association along with working with dieticians and nutritionists.

Herd immunity to COVID-19 unlikely in U.S., experts say

(WTRF) -- Scientist and public health experts believe that herd immunity can't be reached in the U.S. due to the dropping COVID-19 vaccination rates, according to a report from The New York Times.

According to the experts who spoke with the Times, the coronavirus will more likely become a constant but manageable threat in the U.S. for several more years.

“The virus is unlikely to go away,” Emory University evolutionary biologist Rustom Antia told the newspaper. “But we want to do all we can to check that it’s likely to become a mild infection.”

Herd immunity occurs when a sufficient percentage of the population becomes immune to infection. Dr. Anthony Fauci, the nation’s top infectious disease expert, has previously estimated 70% to 85% of the U.S. population needs to be vaccinated to achieve herd immunity.

In addition, new COVID-19 strains are developing at a rate too rapid for herd immunity to be achieved anytime soon, the newspaper reported.

Fauci has now recognized a shift in thinking by experts.

“People were getting confused and thinking you’re never going to get the infections down until you reach this mystical level of herd immunity, whatever that number is,” Fauci said to the Times, adding this is why he stopped using the term "herd immunity."

Experts told the Times if herd immunity isn't possible, the most important goal will be to lower the rate of hospitalizations and deaths.

The total number of lives lost to COVID-19 in the U.S. has eclipsed 575,000, though deaths have plummeted to an average of about 670 per day from a peak of around 3,400 in mid-January.

According to the Centers for Disease Control and Prevention, 39% of the nation's adult population has been fully vaccinated, and over 55% of adults have received at least one dose, up from 30% a month ago.

However, about 8% of those who have gotten one dose of either the Pfizer or Moderna vaccine have not returned for their second shot, officials said. Fauci said it is important to complete the course to gain maximum protection against the virus.

The Associated Press contributed to this report.

America needs to brace itself for more deadly storms, experts say

WASHINGTON (AP) — Deadly weather will be hitting the U.S. more often, and America had better get better at dealing with it, experts said as Texas and other states battled winter storms that blew past the worst-case planning of utilities, governments and millions of shivering citizens.

This week's storms — with more still heading east — fit a pattern of worsening extremes under climate change and demonstrate anew that local, state and federal officials have failed to do nearly enough to prepare for greater and more dangerous weather.

At least two dozen people have died this week, including from fire or carbon monoxide poisoning while struggling to find warmth inside their homes. In Oklahoma City, an Arctic blast plunged temperatures in the state capital as low as 14 degrees below 0 (-25 Celsius).

“This is a different kind of storm,'' said Kendra Clements, one of several businesspeople in Oklahoma City who opened their buildings to shelter homeless people, some with frostbite, hypothermia and icicles in their hair. It was also a harbinger of what social service providers and governments say will be a surge of increased needs for society’s most vulnerable as climate and natural disasters worsen.

Other Americans are at risk as well. Power supplies of all sorts failed in the extreme cold, including natural gas-fired power plants that were knocked offline amid icy conditions and, to a smaller extent, wind turbines that froze and stopped working. More than 100 million people live in areas under winter weather warnings, watches or advisories, and blackouts are expected to continue in some parts of the country for days.

The crisis sounded an alarm for power systems throughout the country: As climate change worsens, severe conditions that go beyond historical norms are becoming ever more common. Texas, for example, expects power demand to peak in the heat of summer, not the depths of winter, as it did this week.

The dire storms come as President Joe Biden aims to spend up to $2 trillion on infrastructure and clean energy investment over four years. Biden has pledged to update the U.S. power grid to be carbon-pollution free by 2035 as well as weatherize buildings, repair roads and build electric vehicle charging stations.

“Building resilient and sustainable infrastructure that can withstand extreme weather and a changing climate will play an integral role” in creating jobs and meeting Biden’s goal of “a net-zero emissions future,” White House press secretary Jen Psaki said Wednesday.

The storms are big news this week, especially in light of their effect on COVID-19 vaccinations as well as freezing Americans, but that doesn't mean they won't become more common, experts say.

“This definitely was an anomaly,'' but one that is likely to occur more frequently as a result of climate change, said Sara Eftekharnejad, assistant professor of electrical engineering and computer science at Syracuse University.

“There probably needs to be better planning, because we're starting to see more extreme weather events across the country,'' she said, whether it's severe cold in Texas or the intense heat wave in California last year that fueled deadly wildfires.

Better forecasting — both short-term and long-term — would help avoid catastrophic failures such as the current outages in Texas and other states, as would large-scale storage systems that can supply electricity when demand spikes and a greater diversity of power sources, Eftekharnejad and other experts said.

Climate change also is hurting military readiness. Damage from a 2018 hurricane at Tyndall Air Force Base in Florida and 2019 flooding at Nebraska’s Offutt Air Force Base, for example, led the Pentagon to send service members as far away as Britain to train.

Another 2018 hurricane that hit North Carolina’s Camp Lejeune, home to one-third of the U.S. Marine Corps’ capability, caused enough damage to degrade training overall, senior U.S. military authorities concluded.

Hardening military installations against worsening natural disasters will cost trillions. But it has to be done, said Joan VanDervort, a former longtime Defense Department climate expert now with the Center for Climate and Security think tank. “We have eyes overseas that are looking at our vulnerability and seeing how we respond. ... There are enemies out there that will certainly take advantage of it.”

Michael Craig, an assistant professor of energy systems at the University of Michigan, said the events in California and Texas show that “what we have now is not going to do it in the face of climate change. It's only going to get worse from here.''

The disaster in Texas and other states “is a reminder that our nation’s critical infrastructure is vulnerable to extreme weather events and we can no longer turn a blind eye to the resiliency investments needed to protect it,'' said Sen. Tom Carper, D-Del., chairman of the Senate Environment and Public Works Committee, who met with Biden at the White House last week.

“The cost associated with addressing climate change and improving our infrastructure’s resilience is always going to be less than the cost of rebuilding or failing to act,'' Carper said.

Meanwhile, federal regulators are looking into the operations of the bulk-power system during the severe winter storm that affected states from Louisiana to Minnesota.

In Texas, where wind power is a growing source of electricity, the wind turbines generally are not equipped to withstand extended low temperatures, as they are in Iowa and other cold-weather states. Modifying the turbines slightly to withstand freezing temperatures is one step needed to confront climate change, said Roy McCann, professor of electrical engineering at the University of Arkansas.

While some Republican politicians, including Texas Gov. Greg Abbott, have tried to pin blame on wind and solar power for the outages, traditional thermal power plants, which rely mostly on natural gas, provide the bulk of power in the state and were the larger problem.

“The entire system was overwhelmed,” said Joshua Rhodes, a research associate on energy issues at the University of Texas.

NCC2020723 Coronaviruses are a group of related viruses that trigger illness in animals as well as birds. In human beings, coronaviruses trigger respiratory system infections that can range from mild to dangerous. Light ailments consist of some cases of the common cold (which has various other feasible causes, primarily rhinoviruses), while extra dangerous selections can trigger SARS, MERS, as well as COVID-19. Symptoms in various other types vary: in hens, they create a top breathing tract illness, while in cows as well as pigs they cause looseness of the bowels. There are yet to be injections or antiviral medications to avoid or treat human coronavirus infections. Coronaviruses comprise the subfamily Orthocoronavirinae, in the family Coronaviridae, order Nidovirales, and also world Riboviria. They are enveloped viruses with a positive-sense single-stranded RNA genome as well as a nucleocapsid of helical symmetry. The genome dimension of coronaviruses varies from about 26 to 32 kilobases, one of the largest amongst RNA viruses. They have characteristic club-shaped spikes that project from their surface, which in electron micrographs develop a photo evocative the solar corona where their name derives.
