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.

‘Momentous’: Alabama shatters five economic records

Alabama Labor Secretary Fitzgerald Washington on Friday announced that Alabama achieved five economic bests in June, setting a new record low unemployment rate, high jobs count, high employment count, high labor force count and low unemployment count.

June’s preliminary, seasonally adjusted unemployment rate was 3.5%, breaking the previous record low of 3.7% from the month previous. June’s rate represents 2,160,931 employed people, another fresh record high, which was 10,456 more employed than last month’s count and 48,952 more than in June 2018.

“Another month, and yet another set of broken records,” Governor Kay Ivey said in a statement.

593

“It’s so exciting to be able to announce these great numbers month after month,” she continued. “It’s always positive to announce a new record low unemployment rate, but we also saw more people working than ever before, fewer unemployed than ever before, more people in the workforce than ever before, and finally, more jobs than ever before. These gains are momentous, and we certainly hope they continue as the year progresses.”

The civilian labor force increased over the year by 39,099 to a record-high 2,240,309. The civilian labor force represents the number of people, aged 16 and over, who are either working or looking for work, excluding the military and those in institutions.

The number of people counted as unemployed dropped to a new record low of 79,378, which represents a drop of 9,853 people from June 2018.

“Let’s talk about jobs. Our economy is supporting more jobs than ever before,” Washington outlined. “There are over 37,000 more jobs in Alabama today than a year ago. Those jobs are coming with the second highest average weekly earnings in history. Workers are earning an extra $44.76 per week than they were a year ago, and $21.91 more than they were just last month. Two of our employment sectors saw their highest average weekly earnings: the trade, transportation, and utilities sector and the professional and business services sector. So not only are we gaining jobs, but Alabamians are bringing home more in their paychecks.”

Total private industry average weekly earnings measured $860.73 in June, up from $838.82 in May and $815.97 in June 2018.
Over the year, wage and salary employment increased 37,300, with gains in the professional and business services sector (+8,000), the construction sector (+7,800) and the leisure and hospitality sector (+6,800), among several others.

Wage and salary employment increased in June by 6,600. Monthly gains were seen in the leisure and hospitality sector (+1,500); the trade, transportation and utilities sector (+1,100); and the construction sector (+1,000), among others.

The trade, transportation and utilities sector and the professional and business sector’s average weekly earnings measured $702.96 and $1,087.97, respectively, which represents both sectors’ record-high earnings.

For the second consecutive month, all 67 counties saw declines in their over-the-year unemployment rates, with drops ranging from half a percentage point to more than three percentage points. Wilcox County, which traditionally has the state’s highest unemployment rate, saw its rate drop by 3.4 percentage points to 7.3%, its third-lowest rate ever.

“To put this in perspective, take a look at Wilcox County. During the recession, the county’s unemployment rate peaked at 31% in February 2010,” Washington advised. “Nearly one in three people in that county’s labor force were out of work. Now, they are at a near record low unemployment rate.”

Counties with the lowest unemployment rates in June were Shelby County at 2.5%, Marshall County at 2.8% and Baldwin County at 2.9%.

Counties with the highest unemployment rates were Wilcox County at 7.3%, Greene and Perry Counties at 6.8% and Clarke County at 6.5%.

Major cities with the lowest unemployment rates were Vestavia Hills at 2.2%, Homewood at 2.3% and Alabaster at 2.4%. Major cities with the highest unemployment rates were Selma at 7.2%, Prichard at 6.6% and Anniston at 4.9%.

Why college football is so popular in the South

As college football prepares to celebrate its 150th birthday, answer this question: Why is this sport more popular in the southern United States than anywhere else in the country?

Three Southeastern Conference football legends offered their opinions Tuesday during the conference’s annual SEC Football Media Days in Hoover. Archie Manning says the answer to that question begins in high school.

“High school football is fantastic in the South,” Manning said. “We also have high school coaches that stay with it for their career. I admire that fraternity. Those men don’t coach high school football for the money. They do it because they love what they do.”

583

Manning also credits warmer weather, a fact Steve Spurrier says encouraged him to play and coach at Florida.

“I visited in late March when it was 72 in Gainesville and 32 in Johnson City, Tennessee,” Spurrier said. “All I know is I was blessed to go there.”

Herschel Walker says the SEC’s strong football programs help draw fans and players.

“The SEC stands with a lot of power,” Walker said. “People know when you’re going to play a team from the SEC — I don’t care who it is, you better bring more than your lunch because it’s going to be a tough game. Guys are going to play extremely hard.”

Why college football is more popular in the South from Alabama NewsCenter on Vimeo.

A number of events celebrating 150 years of college football are scheduled this fall at schools throughout the conference and around the country. In addition, ESPN will be airing “Saturdays in the South,” an eight-part documentary series chronicling the birth and growth of college football in the South.

“You will hear stories of greased railroad tracks, an era before the SEC chant was ever heard, and weave tales through the decades of the modern area of success experienced now by the Southeastern Conference,”  SEC Commissioner Greg Sankey said.

Walker shared his own story of how he used a coin flip to choose between a career in the military or college.

“One Sunday in April, my mom asked me, ‘Don’t you think it’s time for you decide what you’re going to do?’ and before she could say anything, she said, ‘If your mind and your heart is pure of the Lord Jesus, it doesn’t really matter of your decision.’ So I decided to flip a coin. It landed on college. I then flipped a coin between Clemson and Georgia, and it landed on Georgia. I wanted to go to USC out in California, so I flipped a coin between those two schools, and it landed on Georgia again. I then pulled the names out of a bag, and I pulled Georgia, and that’s how I ended up at Georgia.”

“Sometimes when you’re naive and stupid, God will take care of you, because that was the right decision,” Walker added.

He also praised a decision by Georgia to name its football field after Vince Dooley.

“He deserves it because he built men,” Walker said. “To name the field after him, I’m happy to be a part of it.”

All three men say they are honored to remain active in college football activities and discussions about the sport.

“I love the college game,” said Manning, who played quarterback at Ole Miss. “I’ve been involved in the National Football Foundation. I love that involvement. We stay close to the game and try to develop leaders through the game. I’ve certainly enjoyed that.”

“There’s something about football,” Spurrier added. “When you only have one game a year, you have bragging rights for the whole year if you win. There’s always a lot riding on the outcome, and it’s benefited all of us up here.”

“To be a part of anything that’s been around 150 years, you’ve got to be honored,” Walker said. “In today’s world, everyone wants to erase history, (which) I think is a shame. For me to be a part of something that’s 150 years old is incredible.”

7 Things: Abortion ban takes a toll on Ivey, Doug Jones losing support and the feud between Trump and ‘The Squad’ rages on

7. Racial slur spray-painted on Birmingham real estate sign

  • Husband-and-wife real estate team Jeremy and Gina Miller from Birmingham found that one of their “For Sale” signs had a racial slur spray-painted on the sign, but the Millers won’t be pressing charges.
  • While the incident has gained viral attention, the identity of whoever spray painted the sign is still unknown. The Millers have declined to press charges because they don’t think anything good would come from it, and the Millers want to use this situation to spread a positive message to unite people.

6. Ivey taking action on the prison system

501

  • An executive order signed by Governor Kay Ivey will create the Governor’s Study Group on Criminal Justice Policy which will analyze data to help address the serious issues with Alabama’s prison system.
  • Ivey said this study group will lead to more reforms in the system, adding that “we are well on our way to making meaningful progress.”

5. Al Green thinks this impeachment vote was successful

  • After U.S. Representative Al Green’s (D-TX) latest attempt to impeach President Trump, he stated that this attempt wasn’t a complete failure since this time they got almost 100 votes in favor of impeachment, whereas before they had only gotten 58 the first time and 66 the second.
  • Green went on to claim that Trump is causing harm to society, and if he continues to do so “with his inciteful and hateful rhetoric then he will be impeached.”

4. House votes to increase the minimum wage to $15

  • In a brilliant piece of political theater, the House passed a bill that would increase the minimum wage to $15 an hour, setting up a nice battle over the measure in the media, even though it has no chance of passing the GOP-controlled Senate.
  • The bill would increase wages for some but the bill as passed in the House would kill close to 4 million jobs for the lowest earners, speed automation, drive up prices, hurt the economy, shrink family incomes and increase the deficit, inflation and interest rate, according to the Congressional Budget Office.

3. Trump and “The Squad” keep at it

  • According to U.S. Representative Alexandria Ocasio-Cortez (D-NY) and U.S. Representative Ilhan Omar (D-MN), President Donald Trump has moved away from politics, and now “we are in racism…we are in a fascistic government.” They believe criticism against them is violence.
  • Trump is backing away from the “Send her back!” chants at his rally, but continues to point out that he views this as a battle over ideology and love of America. He even tweeted a video that included a Lee Greenwood song and declared America was “ONE ‘SQUAD’ UNDER GOD!”

2. Doug Jones is a one-term Senator

  • Morning Consult released a poll that shows U.S. Senator Doug Jones (D-AL) is losing support in the state, with his 2019 first-quarter approval rating 20% lower than the first quarter of 2018.
  • The poll showed that 39% of registered voters approve of Jones, 37% disapprove and 24% are undecided. His overall his approval rating has gone down 3% since the beginning of 2019.

1. Kay Ivey loses far more ground than other governors that signed abortion bans

  • A flurry of one-sided national and local media attention after signing a bill ban most abortions in the state of Alabama, which her constituents supported, Governor Kay Ivey’s approval rating plummeted 17 points, according to a Morning Consult poll of Governor Approval Rankings
  • While Governor Ivey still sits with a +28 point approval rating, her fall was not mirrored by governors in Missouri, Georgia and Louisiana.

Scofield: ‘Broadband is our infrastructure challenge of the 21st century’ — Crucial ‘to save some of the best areas of this state’

GUNTERSVILLE — Yellowhammer News on Thursday held the second event in its 2019 “News Shapers” series. Entitled “Connecting Alabama’s Rural Communities,” the forum regarding broadband expansion drew a great crowd and elicited insightful conversation from the four expert panelists: State Sen. Clay Scofield (R-Arab), Farmers Telecommunications Cooperative’s Fred Johnson, Central Alabama Electric Cooperative’s Tom Stackhouse and Maureen Neighbors of the Alabama Department of Economic and Community Affairs (ADECA).

Tim Howe, Yellowhammer Multimedia co-owner and Yellowhammer News editor-in-chief, moderated the forum, which came days after the second round of grants was awarded under the Alabama Broadband Accessibility Fund.

1571

This fund was created through legislation sponsored by Scofield and signed into law by Governor Kay Ivey during the Alabama Legislature’s 2018 regular session. The first round of grants was awarded earlier this year. The legislature then passed another bill by Scofield updating the law during the 2019 regular session.

To kick the conversation off on Thursday, Howe noted Scofield’s successful efforts the past two years in passing his broadband expansion legislation, also pointing to HB 400 sponsored by State Rep. Randall Shedd (R-Fairview) and State Sen. Steve Livingston (R-Scottsboro).

Howe asked Scofield about this year’s update of the Alabama Broadband Accessibility Act and the feedback he heard prior to the 2019 regular session that led to him crafting SB 90.

“We passed the broadband expansion bill last year, and we knew that there would be some changes that needed to occur this year — some fine-tuning and some tweaking,” Scofield explained. “And we know that in the future, there will also need to be some fine-tuning as we look to make the program work better… SB 90 reflected some of those changes, and we heard that (the need for changes) from our providers.”

Scofield explained that it is not profitable in many rural areas for companies to install the necessary broadband infrastructure, which is why the Alabama Broadband Accessibility Fund is so important. The fund provides state grants for service providers to supply high-speed internet services in unincorporated areas or communities with 25,000 people or less. Under the law, grant awards cannot exceed 20 percent of the total cost of a project, meaning providers must still have significant “skin in the game” financially.

“At the end of the day, our providers are the ones who are going to be installing the infrastructure for the consumers to enjoy,” Scofield outlined. “So, it’s very important to listen to the providers. This whole thing began by listening to the providers. ‘What is it going to take to get you to expand in rural Alabama?’ And folks, it’s cost. It’s a business decision. The market size is just not there, so the cash flow is just more difficult.”

He likened modern government support of broadband expansion to rural electricity and water expansion of old.

“You’re looking out at Lake Guntersville,” Scofield told the crowd at Guntersville Town Hall, “and it’s a product of government being involved in infrastructure. In the 1930s, the government got involved in rural power. Our co-ops took advantage of that and delivered power to rural customers. And in the 1960s-70s, they expanded to rural water. Well, broadband is our infrastructure challenge of the 21st century.”

“Without our providers, and without government providing some incentive to bring their costs down, it simply wouldn’t occur,” he emphasized. “So, the changes that we’ve seen (through SB 90) are to make the job easier on these guys (the providers).”

‘We still live in a capitalist economy’

Asked to speak to the recommended changes from the provider side, Johnson stressed, “Good public policy has to be based on fact.”

“It’s really easy to blame people for why there’s not broadband in certain parts of the state,” he continued. “But we still live in a capitalist economy — for the time being — and it’s a business case. If it’s (broadband) not there, there’s a really good reason for it. What this legislation does, especially in connection with the federal legislation… what it does is give companies that want to step up to the plate the leverage it may take to swing the pendulum to where a business case can be built and you can serve areas where otherwise there’s no public policy support to build.”

Johnson said he personally thinks “the world of Clay Scofield, Steve Livingston and (House Majority Leader) Nathaniel Ledbetter (R-Rainsville),” who were all in attendance.

“The neatest thing about this (2019 broadband expansion efforts) was you had the leadership in the legislature — and Representative Shedd certainly needs to be included [in that recognition] — they took the time to understand the issue,” he added. “It’s not a Democratic, it’s not a Republican issue. It’s not a partisan issue. It’s an issue that affects all rural Alabamians of every race, color, creed, sex and anything else you want to talk about.”

Of the legislative leaders, Johnson reiterated, “They took the time to understand the issue and ask, ‘What do we need to do to swing the pendulum?’ Quite frankly, I think we’ve got one of the more cohesive public policies in the United States [now]… so I think they’ve done an excellent job.”

Stackhouse affirmed just how important SB 90 and HB 400 were from the perspective of an electric utility provider serving a rural nine-county area in central Alabama.

“80 years ago in November, our [co-op’s] first electric customer was connected… and the area flourished because of getting electricity to an area where a lot said, ‘You can’t make money at that, there’s no use doing that,'” Stackhouse advised. “It was huge.”

Now, in modern times, Central Alabama Electric Cooperative’s board has created a subsidiary to handle communications services, like broadband.

“Communication is now the electricity, and without [the legislation], it just doesn’t happen,” Stackhouse said.

He praised Scofield for his leadership, adding of SB 90 and HB 400, “It has really helped us step up.”

“And we’re not building our [broadband efforts just] on grants, we’ve got a business model we believe we can make work,” Stackhouse continued. “But grants help a lot, though, especially when it’s sparsely populated areas that need it just as much.”

Without broadband expansion, ‘they’re going to die’

Following up on just how much many rural areas in the state really do need broadband access, Howe then recalled an op-ed that Scofield wrote and Yellowhammer News published during the 2019 regular session when Scofield stated the survival of rural Alabama depends on broadband expansion.

Howe asked Scofield to outline the various aspects of modern life that are affected by access to high-speed internet services in his district and others like it across Alabama.

“In about every way you can think of,” Scofield said. “Not just agriculture, but economic development — you’re not going to recruit a company with 21st century jobs to an area without a 21st century infrastructure. You’re not going to train a 21st century workforce without 21st century infrastructure.”

“Telemedicine is the future for our healthcare, which I believe is one of the things that’s going to help bring healthcare costs down for a lot of Americans,” he continued.

Scofield stated that this is especially true, “In rural areas where we see increased levels of diabetes and obesity and a lot of ailments that seem to go up, because the healthcare isn’t easily accessible.”

“So, the thought that a person can connect to MD Anderson for a cancer screening in Greene County, and never leave Greene County, can save that person’s life,” he explained. “It’s a game-changer for a lot of people, and I think that a lot of folks just don’t realize that 830,000 or 840,000 Alabamians still don’t have [broadband] access.”

He then reaffirmed just how crucial these broadband expansion efforts are.

“It’s critical that we get this infrastructure out, that we get people hooked up in our rural areas because they’re going to die — they’re going to be left behind, they’re being left behind right now,” Scofield emphasized. “So, I think the quicker that we do that, the quicker we’re going to save some of the best areas of this state.”

‘This is a legacy’

Later in the forum, Scofield did also caution that broadband expansion to all Alabamians logistically cannot and will not happen instantaneously.

However, success will be achieved only when “we get to a point where, like power … if you want high-speed internet [wherever you live] in the state, you can connect to it,” Scofield believes.

“I think that’s where we’ve got to get,” he said. “And that’s not going to happen overnight… Everyone’s got to be patient. Lake Guntersville didn’t fill up in a day, they didn’t build the dam in a day and they didn’t give power to rural Autauga County in a day — or even here. It’s going to take a long time to build this infrastructure out, but I believe that we are on the right track.”

Scofield wrapped up the forum by lauding the integral support and teamwork of some of his fellow legislators who were in attendance, including Livingston, Ledbetter and State Sen. Andrew Jones (R-Centre), along with Shedd, who was unavailable to make the event.

“I’m really proud of what we came out with,” Scofield said of SB 90 as signed into law. “And I think that whether you’re an elected official or not, if you had something to do with this, I think that this is a legacy that we’re going to be able to leave this state. It’s going to benefit generations. And that’s why I do what I do, and I know that’s why they (the legislators in attendance) do what they do. I think it’s going to be something that’s going to move this state forward in ways that we can’t even envision today.”

On this day in Alabama history: Camp McClellan was established in east Alabama

July 18, 1917

Shortly after the United States entered World War I, the War Department established Camp McClellan as a rapid mobilization base and permanent National Guard facility. More than 27,000 men were training at the east Alabama base by the end of 1917. Camp McClellan was originally named in honor of U.S. Army Maj. Gen. George B. McClellan, and was renamed Fort McClellan in 1929. During World War II, nearly 500,000 military personnel trained there. After being put in custodial status following the war, it was reactivated during the Korean War and Cold War era. The focus shifted to chemical weapons training during and after the Vietnam War. The fort survived one round of military base closings during the 1990s, but it was finally shut down in 1999. The site has shifted to private use as well as for Alabama National Guard training.
