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.

Trump ally Roger Stone makes a last-minute endorsement ahead of Alabama primary runoff

Former Trump advisor Roger Stone is traveling Alabama with Troy King on Monday, touting King’s credentials in an attempt to give him the edge over Attorney General Steve Marshall in Tuesday’s primary runoff election.

“As you can imagine, I get dozens of requests from good candidates, men and women across the country who are supporters of the president and real conservatives,” Stone said at an event Monday morning in Huntsville. “There’s just not enough days in the month, hours in the day to help everybody I’d like to help.”

“But this race is particularly important because the choice could not be more clear-cut,” Stone said.

55

“I hope the people of Alabama will recognize that Steve Marshall is a wolf in sheep’s clothing, a liberal Democrat, posing as a conservative to get through tomorrow’s runoff,” he said.

Stone will be traveling with King to Birmingham, Mobile and Ozark on Monday to reiterate his endorsement pledge.

Steve Marshall returns to campaign in heated AG race with Troy King

Alabama Attorney General Steve Marshall and former Attorney General Troy King are making their final pitches to voters ahead of Tuesday’s Republican runoff.

Marshall returned to the campaign trail Saturday for the first time following the suicide of his wife last month.

Marshall thanked people for supporting him during his loss. He said he never considered dropping out of the race because his wife had urged him to run.

481

“One of the last things that my wife had left for me was a note. She said that I know you are the man for the job and the man for Alabama,” Marshall said.

A group of GOP attorneys generals, including Pam Bondi of Florida, held rallies with Marshall on Saturday in both ends of the state. Bondi said “ethics and integrity mean everything” and others praised his record as a prosecutor.
“We believe in what he’s doing for Alabama and I believe in what he’s doing for President Trump,” Bondi said
Marshall is seeking to win the office in his own right after being appointed last year by then-Gov. Robert Bentley. He previously served 16 years as the district attorney of Marshall County.

Both King and Marshall are stressing their records in the heated runoff.

King, who was attorney general from 2004 to 2011, is seeking a political comeback.

King was appointed as attorney general by then-Gov. Bob Riley. He was elected to a full term in 2006, but he lost the 2010 GOP primary to Luther Strange.

In an interview with the Associated Press, King said he was the true Republican in the race, noting that, as a 10-year-old, he went door-to-door campaigning for Ronald Reagan. Marshall, who was initially appointed by Gov. Don Siegelman, switched to the GOP in 2011.

“On Tuesday this election is about the Republican Party nominating a standard-bearer. Only one of us is a Republican,” King said when asked why runoff voters should choose him.

King will hold a series of Monday rallies with Trump ally Roger Stone.

Both campaigns paused their activities last month following the death of Bridgette Marshall. King said he pulled his commercials from the air for a week after the death out of respect for his opponent.

In returning to the campaign trail, King said he would focus on contrasting their records.

That does not mean the primary has not gotten heated at times.

King criticized Bentley’s appointment of Marshall when Bentley was the subject of an ethics investigation as a “crooked deal.”

King said Marshall got his dream job and “let a man who corrupted Alabama go free.”

Marshall responded that he was ethically required to recuse himself from the investigation, but he appointed an “experienced tough prosecutor” to lead the probe and “six weeks after that Robert Bentley was out of office.” Bentley resigned after pleading guilty to misdemeanor campaign finance violations.

Marshall’s campaign sent out a direct mail piece with unflattering headlines from King’s time as attorney general, including that King had briefly been the subject of a federal grand jury investigation. The probe ended without charges.
King responded that the probe was politically motivated and was leaked to the press to derail his 2010 campaign. He said it ended without charges because he did nothing wrong.

The runoff winner will race Democrat Joseph Siegelman in November.

Alabama among states running speed enforcement task

Alabama joins Georgia and three other states in a week-long speed enforcement operation beginning Monday.

“Operation Southern Shield” will run through Sunday, July 22.

Law enforcement in Georgia and Alabama will join Florida, Tennessee and South Carolina in pulling over drivers who are traveling above legal speed limits on interstates, major highways and local roads.

87

Col. Mark W. McDonough, commissioner of the Georgia Department of Public Safety, says the main focus will be to encourage motorists to slow down. He says they hope the effort will reduce crashes and provide a safer experience for motorists.

The National Highway Traffic Safety Administration says speeding killed more than 10,000 people in the United States in 2016 and was a factor in 27 percent of fatal crashes in the nation.

Alabama man arrested in July 4 boating crash that killed two

A man faces charges in a west Alabama Fourth of July boating crash that killed two people and injured five others.

Al.com reports 29-year-old Richard Latham Jr. was arrested Friday in Tuscaloosa and transported to the Hale County Jail in Greensboro. Latham’s hometown was not released. A woman who answered the phone at the jail would not release that information, referring all calls to the sheriff’s office.

76

Latham faces two counts of reckless murder and is being held without bond. It was unknown if he has an attorney.

Authorities say Latham was drinking and driving a ski boat on the Black Warrior River when the crash happened about four miles south of the Moundville boat landing.

Killed were 46-year-old Richard Glover, of Akron, and 23-year-old Destiny Graben, of Northport.

7 Things: Run-offs continue to be ugly — Trump and Putin one-on-one — 12 Russians and zero Americans indicted — and more …

1. One day left for primaries run-offs across Alabama. AG, Lt. Gov., and AL-02 are most interesting races

— These elections will have very low turnout. 18 percent is the high projection, so if you are reading this, you probably will have a big impact on how these things turn out.

— The ugliness and dishonesty in the two statewide races (Lt. Gov. and AG races) will probably be eclipsed by the midterms and Governor’s race in November.

2. Trump and Putin finally meet after his raucous visits with NATO and the United Kingdom’s Theresa May

464

— Trump’s European tour has been a whirlwind with differences between the U.S. and its allies exposed. Trade deal and defense spending took center stage as a U.S. president fought to put the U.S. first.

— No one knows how the Trump-Putin meeting will go, but the media has already declared that Trump lost. The 12 indictments Friday raised the stakes.

3. Irresponsible media outlets took the weekend to imply that the 12 indictments proved Russian collusion — it did the opposite

— The media seized on two parts of this story from Friday: Roger Stone was involved with people he didn’t know were part of the Russian government and Guccifer 2.0/Wikileaks/DCLeaks are involved with the Russian “hacking” of the DNC.

— Rudy Giuliani laid out the proper response from Trump’s perspective. He said the indictments are good news, the Russians did it, no Americans involved, and Trump is innocent.

4. Deputy Attorney General Rod Rosenstein could be facing impeachment, and probably should be fired

— Apparently, the Trump administration knew these indictments were coming, but the releasing of these indictments on the heels of the Trump-Putin meeting seems like a bad call while the president is overseas.

— Calls for Rosenstein’s impeachment over delays in investigation into FBI agents are gaining steam, but Rep. Trey Gowdy (R-SC) says there is no real reason for it to happen.

5. The beheading of a 13-year-old Alabama girl by a drug cartel in Huntsville goes national and international

— A special-needs Challenger Middle School student was killed by illegal aliens in relation to a drug cartel beef after she saw her grandmother killed.

— The 13-year old’s grandmother apparently double-crossed the cartel and was killed by her boyfriend and ex-boyfriend. Both are in custody.

6. You cannot vote in the GOP runoff if you voted in the Democrat primary, but no one will actually charge you

— Secretary of State John Merrill warned people against voting illegally with a press release saying, “As a result of legislation passed in the 2017 Session of the State Legislature sponsored by Senator Tom Whatley of Auburn and Representative Arnold Mooney of Indian Springs, voters will only be able to cast a ballot for the party that they selected in the June 6th Primary.”

— This does not really matter. We know people are voting illegally and we refuse to have them charged.

7. Illegals are able to vote if they want to — this is undeniable

— Voter ID laws won’t be of much use if illegal voters are still able to register and vote in American elections, which is happening pretty easily. One county in Pennsylvania had 139 illegal voters.

— The only reason we are aware this happens is these individuals self-report as they apply for American citizenship. It’s happening and it’s not being stopped.
