Geoengineering Could Reduce Warming by Half Without Hurting the Planet: New Study

A new study claims that controversial climate engineering techniques could be employed without harming the planet—but not everyone is convinced.

The latest push by long time geoengineering advocate David Keith claims that the controversial climate engineering methods could work to reduce global warming by half without causing any major damage to the planet. The new study used computer modeling to examine the unintended consequences of geoengineering techniques—specifically solar radiation management, a type of geoengineering that involves spraying aerosols into the atmosphere in the hopes of reflecting sunlight and cooling the planet. This type of geoengineering is extremely controversial and previous studies have linked the technology to potentially dangerous outcomes for various parts of the planet.

The new study, recently published in Nature Climate Change, found that setting geoengineering operations within certain limits might prevent unintended consequences like drought and extreme storms. Peter Irvine, a climate and geoengineering researcher at Harvard University and lead author of the study, told Scientific American that his study used computer modeling to determine what might happen if scientists attempt to offset half of the warming as opposed to all of the warming predicted to occur in the coming decades.

Irvine and co-author David Keith state that the study suggests solar geoengineering would not make any water-related changes any worse than already predicted. Keith, a Harvard engineer, has been an advocate for geoengineering for more than a decade and one of the loudest voices in the debate in favor of geoengineering research.

Irvine and Keith’s study examined the effects of geoengineering by region around the world, using the same regions as the Intergovernmental Panel on Climate Change. They evaluated which regions would be made worse by geoengineering or without geoengineering. They found that in the areas of average and maximum temperatures, maximum annual precipitation, and total water availability, no region was made worse by geoengineering. The researchers also claim that hurricanes, typhoons, and other storms would not be worsened and might actually offset some of the effects of climate change on hurricanes.

However, as Scientific American notes, “the study isn’t a completely realistic depiction of potential solar geoengineering scenarios.” The study does not tell us how spraying aerosols in the air might actually affect the world around us. For example, scientists like Keith have recommended spraying strontium, aluminum, barium, and other aerosols from the back of airplanes. There have been no studies examining the effects of these particulates in the soil, air, and water, and how that will affect the environment, animals, and humans.

In a message to The Atlantic, Jane Flegal, a climate-policy researcher and an adjunct faculty member at Arizona State University, writes:

“They are desperately trying to conjure demand for their research topic, but I think they’re hamstringing themselves over the long term by overclaiming. It’s important to keep in mind that this study actually tells us very little about the feasibility of the idea of geoengineering. It is reasonable to ask whether we expect the real world to behave like these models. [And] even if the real world behaved like these models, it is not clear to me that we should expect that this research will inform ‘rational’ decision making in this domain.”

Alan Robock, a climate and aerosols expert at Rutgers University who previously conducted research for the Intergovernmental Panel on Climate Change (IPCC), says the study does not take into account the reality that geoengineering may have additional side effects, like warming certain parts of the atmosphere, changing atmospheric circulation, or affecting the ozone layer.

“I do not agree that ’no area will be significantly worse off under a solar geo-engineering scenario’,” Robock said in an email to Scientific American. “Worse as compared to what? If we rapidly begin mitigation now, that is rapidly reduce our CO2 emissions to zero by switching our power to wind and solar, we will be much better off than a business-as-usual future, or one with geoengineering.”

Interestingly, Robock has previously stated that he believes the Central Intelligence Agency (CIA) may already be using geoengineering techniques as a weapon of war. In 2015, while speaking at the annual meeting of the American Association for the Advancement of Science in San Jose, California, Robock stated he was phoned by two men claiming to be from the CIA, asking whether or not it was possible for hostile governments to use geoengineering, or mass manipulation of the weather, against the United States.

“I got a phone call from two men who said we work as consultants for the CIA and we’d like to know if some other country was controlling our climate, would we know about it?”
[…]
“I’d learned of lots of other things the CIA had done that haven’t followed the rules and I thought that wasn’t how I wanted my tax money spent. I think this research has to be in the open and international so there isn’t any question of it being used for hostile purposes.”

Robock’s statements warrant further investigation, but to those who believe that geoengineering techniques are already being covertly carried out by the U.S. government, his words are further confirmation that mad scientists are desperate to play God. The public and scientific community must examine all of the available evidence which currently shows geoengineering might lead to potential loss of blue skies, lower crop yields, and increases in land and water temperature. The media has already hopped on the geoengineering bandwagon so it’s up to the people to raise awareness and ask questions about this increasingly important topic.

Scientists Shocked After Discovering ‘Strange Creatures’ Nearly a Mile Under Antarctic Ice Shelf

The perplexing community of alien-like creatures wasn’t supposed to be there.

Roughly a mile beneath the icy surface of Antarctica in a remote region 160 miles from sunlight, scientists have accidentally discovered a perplexing set of bizarre creatures, perplexing the researchers who believed the area to be a wasteland wholly devoid of life.

Scientists from the British Antarctic Survey had drilled through 3,000 ft. of ice after melting 20 tons of snow to scoop up seafloor sediment before dropping a camera into the frigid ocean below. However, they soon realized that their tunnel had been dug right above a boulder at the bottom of the ocean, rendering it impossible to gather any sediment.

However, to the shock of the researchers, their camera was able to discover an ecosystem of life that left them confounded with what Wired described as “strange creatures” – two types of filter feeding sea sponges that had never been encountered, dwelling in the – 28.04°F (-2.2°C) water where researchers had believed that no life was possible.

The strange species dwelling in the pitch black waters are living over 200 miles from any known food source, but the creatures still appear to be prospering in spite of the treacherous conditions of the Antarctic sea floor.

The discovery of the strange sea sponges shows just how little we still know about one of the only unexplored regions of the world – and the forms of life that thrive there – where gigantic ice shelves that often rival the size of entire countries have prevented researchers from studying what lies below.

The team’s study laying out the jaw-dropping discovery was published Monday in the journal Frontiers in Marine Science.

“It’s not the most exciting-looking rock—if you don’t know where it is,” British Antarctic Survey biologist Dr. Huw Griffiths told Wired.

Indeed, on close inspection the rock wasn’t only home to the bizarre alien-like sponges – including some shaped like cylinders – but also a film of bacteria known as a microbial mat and a range of stalked organism. Their source of sustenance is what left the scientists befuddled.

Animals that live sessile (or stationary) lives typically rely on a stable supply of food known as “marine snow” – the detritus and remains, sometimes as small as particles, of decomposed sea creatures that sink to the depths of the ocean. Anyone with their own aquarium can imagine what this marine snow looks like.

However, while the source of food might not be apparent, the scientists are guessing that underwater currents are washing in miniscule bits of organic matter from ecosystems that could be as distant as 390 to 930 miles away.

This all still remains a matter of speculation until the next expedition can study this mysterious underwater community much closer. Yet the scientists are eager to find out what these bizarre creatures are and how they ended up in the region in such an inhospitable region in the first place.

“Are they all eating the same food source?” Griffiths asked. “Or are some of them kind of getting nutrients from each other? Or are there more mobile animals around somehow providing food for this community?”

Breathtaking Video Shows Monstrous Avalanche Barrel Down Toward Snowmobilers

Published

on

Gut-wrenching video has gone viral that shows a massive avalanche barreling toward snowmobilers in Utah on Saturday, but the entire group managed to narrowly survive the massive onslaught that nearly closed in on them.

The group had been riding through the Uinta Mountains before the avalanche struck, according to striking video of the aftermath posted to Instagram by snowmobiler Miles Penrose (@backcountrymiles).

“Today we were riding in the Uintas, the snow was great up high and it was finally feeling like we had some base,” Penrose wrote, adding that he had been riding in that part of the mountains since he was 8 years old and was highly familiar with the conditions of the region.

“My brother and I were playing on the side of a hill in the a tree area where [we] have ridden 30-40 times in years past,” he continued.

“As I finished recording my brother playing in the pow, the mountain shook,” Penrose added.

“My original thought was… earthquake. Then it [hit] me, avalanche,” he said.

The terrifying event was also recorded by their friend Nate, who was accompanying them during the ordeal.

As the snow was barreling down the mountain, a man in the video can be heard screaming “Avalanche!”

“Oh sh*t, that’s coming to us,” the terrified man also said.

After Nate can be seen making a mad dash to pull away on his sled to escape the avalanche, the camera suddenly goes dark.

According to Penrose, his safety gear failed to deploy because it had not been turned on. However, he was still swept off his feet by the snow by about 20 yards and was basically “swimming” in the deluge.

Penrose was buried up to his chest in the snow before he fortunately was able to dig himself out. He then rescued his brother, who was buried just up to the top of his head.

“[Then] came the radio chatter,” Penrose said. “Where is everyone at? Was everyone okay? We didn’t realize it but the avalanche had triggered even bigger on the other side of trees where we were.”

Three other party members also managed to survive the terrifying event.

 The avalanche was the second to strike in Utah on that day.

In Mill Creek Canyon, which lies halfway across the state from the Uinta Mountains, eight people from two separate were skiing back country before seven of them were struck by a massive avalanche.

Four of the skiers – two people from each group – were killed. According to the Salt Lake Tribune, the skiers “were young Utahns who reveled in the state’s beauty, pursuing adventures from its ski slopes to its redrock country.”

CNN reports that the four deaths are the most recent in a series of recent deaths caused by avalanches across three states, with the latest deaths bringing the number of fatalities to nine.

Just last week, a man in Utah was killed after being caught in an avalanche near Park City Mountains Canyons Village, just a few miles from the Mill Creek avalanche.

Three other skiers, all local officials, were also killed in an avalanche in Colorado last Monday. Their bodies weren’t recovered until Wednesday.

Also on Wednesday, the body of a skier was recovered following an avalanche at the White Mountain National Forest in New Hampshire.

Biden Expected to Cancel Keystone XL Pipeline Permit on Day One

Avatar

President-elect Joe Biden is reportedly planning on the day of his inauguration to rescind a federal permit allowing construction of the Keystone XL pipeline in the United States, a move environmentalists said would represent an immense victory for the planet attributable to years of tireless Indigenous-led opposition to the dirty-energy project.

CBC News reported Sunday that “the words ‘Rescind Keystone XL pipeline permit’ appear on a list of executive actions supposedly scheduled for Day One of Biden’s presidency,” which begins with his swearing-in on Wednesday. The withdrawal of the Keystone XL permit is among several environment-related actions Biden plans to take via executive order during his first day in office, a list that includes rejoining the Paris climate accord.

“A huge victory for Lakota and Indigenous front liners and Water Protectors. None of this would have been possible without their sacrifices,” Nick Estes, a citizen of the Lower Brule Sioux Tribe and an assistant professor of American studies at the University of New Mexico, tweeted in response to Biden’s reported plan for Keystone XL, a sprawling $8 billion tar sands project that the Trump administration repeatedly sought to advance amid legal challenges and widespread grassroots resistance.

Kendall Mackey, Keep It in the Ground campaign manager for 350.org, said in a statement late Sunday that preventing construction of the Keystone XL pipeline in the U.S. would be a “momentous sign” that Biden “is listening, taking action, and making good on his promises to people and the planet.”

“This decision to halt the Keystone XL pipeline on day one in office sets a precedent that all permitting decisions must pass a climate test and respect Indigenous rights,” said Mackey. “We expect the administration to make similar announcements on Dakota Access Pipeline and Line 3. We celebrate this great victory and the powerful movement to keep fossil fuels in the ground.”

“By ensuring that Keystone XL is reversed,” Mackey continued, “Biden is standing on the side of tribal nations, farmers, ranchers, and many communities whose livelihoods would be wrecked by this dirty pipeline.”

News of Biden’s Inauguration Day plan was met with howls of protest from right-wing Canadian politicians such as Alberta Premier Jason Kenney, who issued a statement Sunday threatening legal action if Biden follows through on yanking the permit for Keystone XL, owned by Canada-based company TC Energy. Last March, as Common Dreams reported, the government of Alberta committed around $1.1 billion USD to the pipeline project.

“I am deeply concerned by reports that the incoming administration of President-elect Joe Biden may repeal the presidential permit for the Keystone XL border crossing,” Kenney tweeted, a response that was immediately panned by climate activists.

In a last-ditch effort to rescue its long-delayed Keystone XL project, TC Energy is reportedly “committing to spend $1.7 billion on solar, wind, and battery power to operate the partially completed 2,000-mile pipeline system between Alberta, in western Canada, and Texas,” according to the Wall Street Journal.

The attempt to brand Keystone XL as an environmentally friendly and sustainable energy project was swiftly ridiculed, with one journalist accusing TC Energy of a “desperate” effort to put “lipstick on its pig.”

Dallas Goldtooth, Keep It in the Ground campaign organizer for the Indigenous Environmental Network, said in response to Biden’s plan to rescind the pipeline permit that “our communities have been fighting KXL for over a decade, tooth and nail, in the dirt and in the courts.”

“We formed an immensely powerful, unlikely alliance of voices and we never gave up,” said Goldtooth. “I will wait for the ink to dry before I fully celebrate, but s*** this feels good.”
