There are thousands of tonnes of methane emissions being released by melting glaciers: study

Published

 on

Our current projections for fighting climate change are based on the greenhouse gas sources that we already know about — but we could be dangerously underestimating, according to a new study looking at a greenhouse gas source that has, up until this point, been hidden under ice.

Researchers have found that as glaciers shrink, they’re exposing more and more bubbling groundwater springs, releasing an unknown amount of the potent greenhouse gas methane into the atmosphere.

“These springs are a considerable, and potentially growing, source of methane emissions — one that has been missing from our estimations of the global methane budget until now,” Gabrielle Kleber, lead author of the research with the University of Cambridge’s Department of Earth Sciences, said in a press release.

Kleber and her team have been monitoring the water chemistry of more than a hundred hot springs across Norway’s Svalbard Islands for the past three years, a region which is warming around two degrees faster than the average rate for the Arctic.

They observed that as glaciers retreat, revealing groundwater springs, those springs are emitting huge amounts of methane. These emissions could exceed 2,000 tonnes annually.

Scientists have been concerned about greenhouse gases that could be revealed in the Arctic by warming temperatures for a long time, but previous research has largely focused on the emissions that result from permafrost melting.

This study enabled researchers to focus on specifically the impact of glaciers melting.

“While the focus is often on permafrost, this new finding tells us that there are other pathways for methane emissions which could be even more significant in the global methane budget,” Alexandra Turchyn, a professor with Cambridge’s Department of Earth Sciences and study co-author, said in the release.

The amount of emissions the study predicts glaciers could cause over the course of a year is equal to 10 per cent of the methane emissions from Norway’s annual oil and gas energy industry, the release stated.

“Until this work was conducted, we didn’t understand the source and pathways of this gas because we were reading about studies from completely different parts of the Arctic where glaciers are absent,” Andrew Hodson, a professor with the University Centre in Svalbard and study co-author, said in the release.

Svalbard is the canary in the coal mine of glacier and climate change research, authors say.

“Living in Svalbard exposes you to the front-line of Arctic climate change,” Hodson said. “I can’t think of anything more stark than the sight of methane outgassing in the immediate forefield of a retreating glacier.”

The springs in question are fed by “a plumbing system hidden beneath most glaciers” the release explained. When glaciers retreat as they melt, they reveal these groundwater reserves to the air.

Researchers searched for these new groundwater springs by picking them out from satellite images, identifying them as threads of blue on the top of ice. Kleber would then drive out to the springs on a snowmobile to take samples of the water wherever there was evidence that the ice was blistering due to built up gas from the spring underneath the fresh layer of ice.

Their analysis showed high concentrations of dissolved methane.

“In Svalbard we are beginning to understand the complex and cascading feedbacks triggered by glacier melt — it seems likely that there are more outcomes like this which we have yet to uncover,” said Kleber.

This is just the tip of the iceberg, researchers say — quite literally.

“The amount of methane leaking from the springs we measured will likely be dwarfed by the total volume of trapped gas lying below these glaciers, waiting to escape,” Hodson said. “That means we urgently need to establish the risk of a sudden increase in methane leakage, because glaciers will only continue to retreat whilst we struggle to curb climate change.”

The body of a Ugandan Olympic athlete who was set on fire by her partner is received by family

Published

 on

 

NAIROBI, Kenya (AP) — The body of Ugandan Olympic athlete Rebecca Cheptegei — who died after being set on fire by her partner in Kenya — was received Friday by family and anti-femicide crusaders, ahead of her burial a day later.

Cheptegei’s family met with dozens of activists Friday who had marched to the Moi Teaching and Referral Hospital’s morgue in the western city of Eldoret while chanting anti-femicide slogans.

She is the fourth female athlete to have been killed by her partner in Kenya in yet another case of gender-based violence in recent years.

Viola Cheptoo, the founder of Tirop Angels – an organization that was formed in honor of athlete Agnes Tirop, who was stabbed to death in 2021, said stakeholders need to ensure this is the last death of an athlete due to gender-based violence.

“We are here to say that enough is enough, we are tired of burying our sisters due to GBV,” she said.

It was a somber mood at the morgue as athletes and family members viewed Cheptegei’s body which sustained 80% of burns after she was doused with gasoline by her partner Dickson Ndiema. Ndiema sustained 30% burns on his body and later succumbed.

Ndiema and Cheptegei were said to have quarreled over a piece of land that the athlete bought in Kenya, according to a report filed by the local chief.

Cheptegei competed in the women’s marathon at the Paris Olympics less than a month before the attack. She finished in 44th place.

Cheptegei’s father, Joseph, said that the body will make a brief stop at their home in the Endebess area before proceeding to Bukwo in eastern Uganda for a night vigil and burial on Saturday.

“We are in the final part of giving my daughter the last respect,” a visibly distraught Joseph said.

He told reporters last week that Ndiema was stalking and threatening Cheptegei and the family had informed police.

Kenya’s high rates of violence against women have prompted marches by ordinary citizens in towns and cities this year.

Four in 10 women or an estimated 41% of dating or married Kenyan women have experienced physical or sexual violence perpetrated by their current or most recent partner, according to the Kenya Demographic and Health Survey 2022.

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”

B.C. sets up a panel on bear deaths, will review conservation officer training

Published

 on

 

VICTORIA – The British Columbia government is partnering with a bear welfare group to reduce the number of bears being euthanized in the province.

Nicholas Scapillati, executive director of Grizzly Bear Foundation, said Monday that it comes after months-long discussions with the province on how to protect bears, with the goal to give the animals a “better and second chance at life in the wild.”

Scapillati said what’s exciting about the project is that the government is open to working with outside experts and the public.

“So, they’ll be working through Indigenous knowledge and scientific understanding, bringing in the latest techniques and training expertise from leading experts,” he said in an interview.

B.C. government data show conservation officers destroyed 603 black bears and 23 grizzly bears in 2023, while 154 black bears were killed by officers in the first six months of this year.

Scapillati said the group will publish a report with recommendations by next spring, while an independent oversight committee will be set up to review all bear encounters with conservation officers to provide advice to the government.

Environment Minister George Heyman said in a statement that they are looking for new ways to ensure conservation officers “have the trust of the communities they serve,” and the panel will make recommendations to enhance officer training and improve policies.

Lesley Fox, with the wildlife protection group The Fur-Bearers, said they’ve been calling for such a committee for decades.

“This move demonstrates the government is listening,” said Fox. “I suspect, because of the impending election, their listening skills are potentially a little sharper than they normally are.”

Fox said the partnership came from “a place of long frustration” as provincial conservation officers kill more than 500 black bears every year on average, and the public is “no longer tolerating this kind of approach.”

“I think that the conservation officer service and the B.C. government are aware they need to change, and certainly the public has been asking for it,” said Fox.

Fox said there’s a lot of optimism about the new partnership, but, as with any government, there will likely be a lot of red tape to get through.

“I think speed is going to be important, whether or not the committee has the ability to make change and make change relatively quickly without having to study an issue to death, ” said Fox.
