Upcoming research will buck the ‘consensus’ and show Antarctica is still gaining ice

Is Antarctica melting or is it gaining ice? A recent paper claims Antarctica’s net ice loss has dramatically increased in recent years, but forthcoming research will challenge that claim.

NASA glaciologist Jay Zwally first challenged the “consensus” on Antarctica in 2015 when he published a paper showing ice sheet growth in eastern Antarctica outweighed the losses in the western ice sheet.

Zwally will again challenge the prevailing narrative of how global warming is affecting the South Pole. Zwally said his new study will show, once again, the eastern Antarctic ice sheet is gaining enough ice to offset losses in the west.

Much like in 2015, Zwally’s upcoming study will run up against the so-called “consensus,” including a paper published by a team of 80 scientists in the journal Nature on Wednesday. The paper estimates that Antarctic is losing, on net, more than 200 gigatons of ice a year, adding 0.02 inches to annual sea level rise.

“Basically, we agree about West Antarctica,” Zwally told The Daily Caller News Foundation. “East Antarctica is still gaining mass. That’s where we disagree.”

Reported ice melt mostly driven by instability in the western Antarctic ice sheet, which is being eaten away from below by warm ocean water. Scientists tend to agree ice loss has increased in western Antarctica and the Antarctic Peninsula has increased.
Measurements of the eastern ice sheet, however, are subject to high levels of uncertainty. That’s where disagreements are.

“In our study East Antarctic remains the least certain part of Antarctica for sure,” Andrew Shepherd, the study’s lead author and professor at the University of Leeds, told TheDCNF.

“Although there is relatively large variability over shorter periods, we don’t detect any significant long-term trend over 25 years,” Shepherd said.

However, Zwally’s working on a paper that will show the eastern ice sheet is expanding at a rate that’s enough to at least offset increased losses the west.

The ice sheets are “very close to balance right now,” Zwally said. He added that balance could change to net melting in the future with more warming.

So, why is there such a big difference between Zwally’s research and what 80 scientists recently published in the journal Nature?

There are several reasons for the disagreement, but the biggest is how researchers make what’s called a glacial isostatic adjustment (GIA), which takes into account the movement of the Earth under ice sheets.

Scientists use models to measure the movement of land mass in response to changes the ice sheet sitting on top. For example, Zwally said eastern Antarctica’s land mass has been going down in response to ice sheet mass gains.

That land movement effects ice sheet data, especially in Antarctica where small errors in GIA can yield big changes ice sheet mass balance — whether ice is growing or shrinking. There are also differences in how researchers model firn compaction and snowfall accumulation.

“It needs to be known accurately,” Zwally said. “It’s an error of being able to model. These are models that estimate the motions of the Earth under the ice.”

Zwally’s 2015 study said an isostatic adjustment of 1.6 millimeters was needed to bring satellite “gravimetry and altimetry” measurements into agreement with one another.

Shepherd’s paper cites Zwally’s 2015 study several times, but only estimates eastern Antarctic mass gains to be 5 gigatons a year — yet this estimate comes with a margin of error of 46 gigatons.

Zwally, on the other hand, claims ice sheet growth is anywhere from 50 gigatons to 200 gigatons a year.

Shepherd’s recently published paper found Antarctica lost 219 billion tons of ice from 2012 to 2017, about triple what annual ice mass loss was in the previous decade.

“There are several potential reasons for the remaining disagreement among the various satellite techniques, such as the models we use to account for snowfall and glacial isostatic adjustment,” Shepherd told TheDCNF.

“But the ice losses we detect in West Antarctica are highly accurate, and outstrip by far the signal or uncertainty in East Antarctica,” he said.

Zwally said the ice sheets are reacting to climate warming, the question is when receding started and how far it would go.

Illegal immigrant charged in death of Mobile woman

Domingo Francisco Marcos, a Guatemalan immigrant in the United States illegally, has been charged with vehicular homicide and fleeing the scene of the accident with injuries in the Monday death of Mobile’s Sonya Jones on US 98.

215

According to WKRG, the Mobile County District Attorney’s Office said Marcos, 16, hit Jones’ vehicle head-on and then tried to run away. However, he was injured too badly to do so and collapsed after leaving the immediate scene.

Marcos was then taken to USA Women’s and Children’s Hospital for surgery. Prosecutors plan on asking the judge not to grant him bond.

He reportedly entered the country via Mexico and was apprehended in Arizona by federal law enforcement officials in 2017. Before he could be deported, he claimed asylum and was released awaiting a hearing. Marcos never showed up in court to speak to his claim, so it was denied. However, authorities had no way to locate him so he was never deported.

In a statement, Congressman Bradley Byrne (AL-1), who represents the Mobile area, decried yet another illegal immigrant allegedly responsible for the death of an Alabamian.

“Yet again we have someone who is in our country illegally taking the life of an American citizen,” Byrne said. “How many more Americans have to die before we take action to crack down on illegal immigration, secure the border, and keep the American people safe? Enough is enough!”

Will Ainsworth: Common Core is a failed, Obama-era relic that must come to a quick and immediate end

Alabama took a strong step toward independence in its public schools this week when the State Senate approved legislation to repeal the Obama-era curriculum mandates known by most as Common Core.

Everyone agrees that Alabama needs strict academic standards that our children must meet. It is vital to economic development, it is vital to our workforce development and it is vital to our children’s future success.

Where we differ in the Common Core debate is who should set those standards.

405

I believe Alabamians should determine the curriculum and standards for our state’s schoolchildren based upon our available resources, our needs and our first-hand knowledge of what makes Alabama great.

We should not rely upon some out-of-state entity or liberal, Washington, D.C. bureaucrats to determine our standards, and we certainly should not continue embracing this most damaging legacy of the disastrous Obama administration.

When Thomas Jefferson said, “The government closest to the people serves the people best,” he understood that a top-down approach and governing from afar denies the important knowledge and details that those on the local level possess.

Perhaps the most asinine theory behind Common Core mandates is the cookie cutter approach it takes to schools across our nation.

Rather than recognizing and accounting for the differences among the states, their workforce needs, and the public educations they should offer, Common Core demands an across-the-board, one-size-fits-all mandate that is typical of liberal policy pronouncements.

Moreover, the public schools in a politically conservative state like Alabama, where character education and allowing students to acknowledge God are important, are vastly different from the schools in ultra-liberal cities like San Francisco and New York City, where educators consider themselves enlightened and the groupthink doctrine of political correctness dominates.

But, in the end, the most effective argument for repealing Common Core is the fact that it has proven to be an unmitigated failure.

When Alabama first adopted Common Core roughly a decade ago, advocates labeled it as the cure-all for our public education system, but the magic elixir they promised has proven to be just a worthless bottle of snake oil.

Prior to the adoption of Common Core, Alabama’s students ranked at or near the bottom in almost every education metric that was tested, and, a decade later today, our state still ranks 49th in math and 46th in reading.

For these stated reasons and too many others to detail, it is time for Alabama to abandon this liberal social experiment and chart its own, independent path toward success in education – one that is rooted in conservative principles and one that embraces long-proven, fundamental teaching concepts.

Sen. Del Marsh (R-Anniston), who filed the legislation, and the co-sponsors of his bill should be commended for working to end this unnecessary Obama-era relic. Dropping the gavel when the repeal of Common Core passed the State Senate was one of the happiest and most satisfying moments of my time in public service.

Will Ainsworth is the Republican lieutenant governor of Alabama.

Bill to repeal Common Core in Alabama passes Senate

MONTGOMERY — Senate President Pro Tem Del Marsh’s (R-Anniston) bill to eliminate Common Core in the state of Alabama passed the State Senate as amended by a 23-7 vote on Thursday afternoon, despite a passionate filibuster by Democrats in the chamber.

The bill, SB 119, now heads to the House to take up after the legislature’s spring break next week.

360

SB 119 was given a unanimous favorable recommendation on Wednesday by the Education Policy Committee.

State Sen. Garlan Gudger (R-Cullman) introduced a friendly amendment that was adopted by the Senate before they passed the bill. The amendment would move Alabama away from Common Core standards directly to new standards adopted by the state school board in 2021-2022 (instead of using transition standards next school year and then new standards in 2020-2021).

Gudger’s amendment also addressed concerns that the bill would inadvertently bar Alabama from utilizing things like AP tests and national certifications and exams.

Lt. Governor Will Ainsworth (R-AL), who presides over the Senate, told Yellowhammer News Wednesday that he strongly supports the repeal of Common Core.

Update 4:20 p.m.:

Marsh released the following statement:

In the past I have made it clear that we have an elected school board who should dictate policy when it comes to education in Alabama. However it is clear that we have a dysfunctional school board who is incapable of making decisions that give our students and teachers the best chance at being successful.

We have used the Common Core standards in Alabama for nearly a decade and while we do have some blue-ribbon schools, the vast majority are severely behind. We are still ranked 46thand 49thin reading and math according to National Assessment of Educational Progress. This is unacceptable so it is time to try something new.

I have worked and will continue to work with the education community in developing high standards so that we have the most competitive and rigorous course of study in the country, we cannot accept the status quo and this is a good first step.

I want to thank the Senate for their support and their work as we ended up with a piece of legislation that went through the legislative process to become the best possible bill we could pass and addressed everybody’s concerns. This was a fantastic first step as we move to address sweeping education reform in Alabama.

Marsh’s bill to help build Trump’s wall passes Senate

MONTGOMERY — Senate President Pro Tem Del Marsh’ bill (R-Anniston) that would voluntarily allow a taxpayer to divert a portion or all of their own state income tax refund to We Build the Wall, Inc. passed the Senate by a vote of 23-6 on Thursday afternoon, overcoming an organized Democrat filibuster.

The bill, SB 22, now is set for a first reading in the House, which can take up the legislation after the legislature’s spring break next week.

“I thank the Senate for their support on this matter and I look forward to working with the House to give Alabamians a voice and are able to express their desire to support President Trump and stronger border security,” Marsh said in a statement.

192

After Minority Leader Bobby Singleton (D-Greensboro) started a filibuster Wednesday, Marsh carried the bill over.

On Thursday, the bill was named to the Senate special order calendar and was again filibustered when it came up, this time with multiple Democrat senators joining in the effort. Republicans, seeing the filibuster was set to continue for hours, successfully adopted a cloture petition to end the filibuster so the Democrats would not continue blocking the chamber from conducting business.

“People I talk to across Alabama are sick and tired of politicians in Washington D.C. talking and nothing being done about the crisis on our borders. This bill is about sending a message to Washington that we support President Trump and his mission to secure our southern border,” Marsh advised.

He added, “Alabamians overwhelming favor securing our borders, protecting our citizens and their jobs and supporting President Trump. This bill simply allows citizens, if they choose, to send a message that they want to see our borders secured by sending a portion of their tax refund to donate to build the wall.”

BONEFROG, ‘The world’s only Navy SEAL obstacle course race’ heads to Alabama this Saturday

Do you love anything military, obstacle course or NASCAR racing-related? If so, you’ll want to head down to Talladega Superspeedway this Saturday for BONEFROG. With obstacles placed every quarter mile, BONEFROG is sure to test even the most seasoned athletes.

372

Brian Carney, CEO and Founder of BONEFROG, said the race is designed to push racers past their limits and see that they can accomplish anything they set their minds to.

“We try to replicate the same type of obstacles we trained on in SEAL training but on a smaller and safer scale,” said Carney. “With BONEFROG you can feel the military authenticity throughout the entire event and especially throughout the course.”

This year, the race will offer several options: the 3-mile Sprint, 6-mile Challenge, 9-mile TIER-1, 8 Hour Endurance and the all-new 18+ mile TRIDENT.

For those with children, BONEFROG will also offer quarter and half-mile courses with scaled down obstacles.

Set up at Alabama’s historic Talladega Speedway, Carney says the Alabama BONEFROG race isn’t one to miss.

“There’s so much history here and we utilize every inch of the speedway to make this race stand out from any other. If you’re coming to BONEFROG to race then Talladega tops them all in that department,” Carney said.

At BONEFROG racers can expect not only to be challenged but inspired. Carney says he will never forget watching Alabama veteran, and former Dancing with the Stars contestant Noah Galloway complete the race’s Black OP’s obstacle.

“For those who don’t know, Noah’s an army vet who lost an arm and a leg in combat. To see him on the monkey bars in front of our massive American Flag taking on one of our toughest obstacles just sent chills through my body,” Carney said.

Carney continued, saying that moment continues to linger in his memory.

“To say it was inspirational would be a massive understatement. It’s stayed with me ever since and pushed me and my entire team to always strive to put on the best events we possibly can because our racers deserve just that.”

With 20,000 to 30,000 racers expected to participate in this year’s BONEFROG races, it’s safe to say popularity is unmatched.

More than just a fun and challenging race, BONEFROG partners with nonprofits, like the Navy SEAL Foundation, to give back. Carney said the company has raised over $200,000 for charity to date.

If you’re ready to test your limits and join the race, there’s still time. To register or to learn more about the company, visit the BONEFROG website at www.bonefrogchallenge.com
