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.

Sessions hits Jones over finding impeachment case ‘compelling’ — ‘Merely repeating the partisan attacks of Congressman Adam Schiff’

Former U.S. Attorney General Jeff Sessions is not happy with Senator Doug Jones (D-AL).

Sessions sent out a forceful response to Yellowhammer News’ reporting on Friday morning that Jones found the evidence against President Donald Trump in the impeachment trial “compelling.”

“Senator Doug Jones’ recent video appears to indicate that he is planning to vote to remove Donald Trump from the office of President of the United States. He is merely repeating the partisan attacks of Congressman Adam Schiff,” began Sessions.

162

Sessions said he feels Jones is “not even attempting” to represent the people of Alabama.

Presumably, this is a reference to Jones’ openness to impeaching Trump, who sports around a 60% approval rating among the people of Alabama. It is also good political hay for Sessions to make in a Republican primary where Trump’s approval rating hovers around 90%.

“The Democrats do not allege any crime, nor do the vague charges in the articles of impeachment rise to a level that would justify the removal of our duly-elected President,” added Sessions.

Sessions this week was the subject of a much speculated-about Trump tweet that showed a poll from 2019 that had Sessions leading the field of contenders in the Republican primary.

To conclude his statement on impeachment, Sessions said, “The entire matter is being revealed as a political hit job, paid for by the taxpayers.”

Tuberville: ‘Trump has done more for the rights of the unborn than any other President’

After President Donald J. Trump on Friday became the first sitting president in history to address the March for Life in Washington, D.C., former Auburn University head football coach Tommy Tuberville praised Trump’s staunch pro-life stance.

Tuberville is a candidate in Alabama’s 2020 Republican primary for the U.S. Senate.

Trump’s speech can be viewed below:

Tuberville said in a statement to Yellowhammer News, “President Trump attending the March For Life Rally is a victory for all in the Pro-Life movement.”

“President Trump has done more for the rights of the unborn than any other President,” he concluded. “I’ll continue to fight for the unborn with President Trump when elected to the Senate. It’s simple: life begins at conception!”

Friday’s March for Life occurred two days after the 47th anniversary of the U.S. Supreme Court’s Roe v. Wade decision.

RELATED: Tuberville ‘all for’ abortion ban — ‘You’ve got to take your hat off to not just Alabama but other states’ on effort to overturn Roe v. Wade

One of the other featured speakers at the 2020 March for Life has a major Alabama tie.

David Platt, formerly the pastor of the Church at Brook Hills in Birmingham, Alabama, was highlighted on the March for Life’s website as a keynote speaker. Platt made national news last year when Trump showed up to his current church in Virginia; the pastor then movingly prayed over the president on stage.

Bama, Auburn combine for three of four SEC players in 2020 State Farm All-Star Football Challenge

The 22nd annual State Farm All-Star Football Challenge will return to AT&T Stadium in Arlington, Texas, and air on ESPN2 at 8:00 p.m. CT on January 31.

The exclusive skills competition will feature 24 of college football’s brightest stars divided into six teams based on their college conference. The conferences represented are the ACC, the Big Ten, the Big 12, the Pac-12, the SEC and four of the best players outside of the Power Five that will be called the “Wild Card” team.

Of the four players on the SEC team, the University of Alabama had two, Auburn had one and Vanderbilt had the fourth and final player.

199

Team SEC as follows:

Nick Coe, DE, Auburn
Jerry Jeudy, WR, Alabama
Terrell Lewis, LB, Alabama
Riley Neal, QB, Vanderbilt

Each player will individually participate in a timed event, and the competition will then finish with a full team event. All events will be timed and have individual winners, which will be compiled into a cumulative score to determine the winning team. For example, the quarterbacks from each team will compete against each other to win their competition. Ultimately, however, their time will be added to the times of the other competitors on their conference designated team to have a final team score.

Individual events will include the State Farm QB Accuracy Competition, the Mercedes-Benz Obstacle Course, the Rocket Mortgage Strength Challenge and the Hands Competition. To conclude the program, the players will compete as teams in the State Farm Team Competition.

Alumni of the State Farm All-Star Football Challenge include 81 first-round NFL Draft picks, including 38 Pro Bowlers, such as Drew Brees, Aaron Rodgers, Patrick Mahomes, Jalen Ramsey, Dalvin Cook, Derwin James, Landon Collins, Von Miller, Vernon Davis, Joe Flacco, Dez Bryant, Donovan McNabb, Reggie Wayne and Edgerrin James.

Alabama finishes decade with record low unemployment rate, sets more economic milestones

Alabama Department of Labor Secretary Fitzgerald Washington on Friday announced that the state maintained its record low unemployment rate last month, ending 2019 with a preliminary, seasonally adjusted December unemployment rate of 2.7%, unchanged from November, and far below December 2018’s rate of 3.8%.

Multiple other economic records were again set last month, in addition to the record low unemployment rate holding steady.

In a statement, Governor Kay Ivey said, “I’m so proud to be able to close out this decade with record-breaking economic measures.”

440

December’s unemployment rate, which ranked fifth-lowest in the nation, represented 2,204,740 employed people, a new record high, representing an increase of 83,971 from December 2018. Additionally, 61,458 people were counted as unemployed, another new record and a drop of 22,051 from last year. Moreover, the civilian labor force grew by 61,920 over the year to a new record high of 2,266,198.

“All year long, we’ve had good news to share, and to be able to end the year, and the decade, on such a positive note is wonderful,” the governor concluded. “Earlier this year, Alabama had never reported an unemployment rate lower than 3.0%, and now we’ve had one for the last three months! Nearly 84,000 more people have jobs now than last year. I’m excited about the path that Alabama is on, and the positive impacts this news has on our people.”

Wage and salary employment grew over the year by 46,300. Yearly gains were seen in the professional and business services sector (+15,000), the leisure and hospitality sector (+7,800) and the government sector (+6,100), among others. Over the month, gains were seen in the trade, transportation and utilities sector (+4,000), the construction sector (+700) and the professional and business services sector (+200).

“For the eleventh month in a row, our job growth has met or surpassed the nation’s,” Washington stated. “We’ve gained over 46,000 jobs since last December, and we continue to see employers posting job ads.”

Additionally, Alabama’s job growth rate for December was 2.2%. It significantly surpassed the national job growth rate of 1.4%, marking the 11th month that Alabama’s job growth rate matched or exceeded the national rate in 2019.

“Average weekly wages showed significant growth this month, registering at an all-time high,” Washington added. “Additionally, we saw many sectors and subsectors reach all-time wage highs, including manufacturing, with a monthly wage increase of $25.57, and financial activities, with a monthly wage increase of $50.78.”

Total private average weekly wages measured $875.44 in December, representing a monthly increase of $15.14.

Counties with the lowest unemployment rates last month were: Shelby County at 1.8%; Marshall, Madison and Cullman Counties at 2.1%; and Tuscaloosa, St. Clair, Morgan, Limestone, Lee and Elmore Counties at 2.2%.

Counties with the highest unemployment rates were: Wilcox County at 6.8%, Clarke County at 5.5% and Greene and Lowndes Counties at 4.8%.

Major cities with the lowest unemployment rates were: Vestavia Hills at 1.4%, Homewood at 1.6% and Hoover and Northport at 1.7%.

Major cities with the highest unemployment rates were: Prichard at 5.0%, Selma at 4.9% and Bessemer at 3.7%.

What does Trump’s tweet say about his position on the U.S. Senate race in Alabama?

After remaining silent on the GOP primary in 2020 U.S. Senate race for the state of Alabama, the President of the United States has checked in via Twitter.

But what does it mean?

218

The answer to this question all depends on how you lean in the race.

Do you support former Attorney General Jeff Sessions?

Trump is happy he is leading!

Do you support former Auburn head football coach Tommy Tuberville?

Trump is happy that Tuberville is close to Sessions (he did tweet a poll put out by a pro-Tuberville group)!

Do you support U.S. Representative Bradley Byrne (R-Fairhope)?

Trump is bringing attention to the race to get people to pay attention to all of the ads on television and radio by the Byrne campaign.

Do you support former Alabama Chief Justice Roy Moore?

Hey, at least Trump didn’t say he wanted Moore out of the race again.

Do you support State Representative Arnold Mooney (R-Indian Springs)?

Hey look, Arnold Mooney is included!

Do you support Stanley Adair?

Hi, Stanley!

Before anyone gets too excited, Trump was tweeting about a bunch of races, so maybe it means nothing.

Also, let’s remember that Trump was 0-2 in 2017. He backed then- Senator Luther Strange (R-AL) for reelection to the seat he was appointed to and he then begrudgingly backed Roy Moore. Obviously, the existence of U.S. Senator Doug Jones (D-AL) shows he was not successful in either endeavor.

Because of this, President Donald Trump should just sit this one out.
