Massive Antarctic Ice Shelf Days From Breaking Off
By Andy Rowell
Any day now we will truly witness climate change in action. Within days at worst, maybe weeks at best, scientists predict that a huge section of the Larsen C ice shelf in Antarctica will break off into the ocean, in what is called a major "calving" event.
The size of the U.S. state of Delaware or the paradise island of Bali, the iceberg will be one of the biggest ever seen.
Massive Crack in Larsen C Ice Shelf Grew 11 Miles in 6 Days https://t.co/vg7nFZHcNC @MIDASOnIce @climatehawk1 @ClimateReality @NRDC @350— EcoWatch (@EcoWatch)1496337007.0
For months, scientists have been watching the growing crack spread some 175 kilometers (approx. 108 miles) along the ice sheet with growing alarm. Now just 13 kilometers (8 miles) remain, keeping this chunk of ice attached to the main ice shelf.
In glacial terms, it is literally hanging by a thread.
"It's keeping us all on tenterhooks," Andrew Fleming of the British Antarctic Survey told Reuters earlier this week. "It feels like a niggling tooth" of a child as it comes loose.
According to scientists from Project MIDAS, a UK-based Antarctic research project investigating the effects of a warming climate on the Larsen C ice shelf: "When it calves, the Larsen C Ice Shelf will lose more than 10 percent of its area to leave the ice front at its most retreated position ever recorded; this event will fundamentally change the landscape of the Antarctic Peninsula."
As the scientists pointed out, as the ice-shelf is already floating, an iceberg breaking off does not directly impact sea level rise, although "the ice shelf is holding back land-based glaciers, which have a large sea level potential."
So what should we name this vast new iceberg when it carves? The folks at 350.org have come up with a novel idea: Let's name it #ExxonKnew, because "50 years after learning the truth about climate change, Exxon's climate denial is having increasingly devastating consequences."
350.org outlines that the imminent calving of the vast iceberg is "one of the most dramatic displays of the destruction Exxon and their peers in the fossil fuel industry have unleashed upon the planet. Exxon's climate denial created this iceberg. It should be named after it too."
Ironically, way back in the early sixties, a division of the company that would become Exxon ran a full page ad in Life Magazine bragging about their ability to melt glaciers.
Later that decade, by 1968, a report for the American Petroleum Institute, on which Exxon is a prominent member, warned of the dangers of climate change and the risks to sea level rise if Antarctic glaciers melted.
Nine years later in 1977, Exxon's leaders were told directly by a senior company scientist, James F. Black, about the looming climate crisis. "In the first place, there is general scientific agreement that the most likely manner in which mankind is influencing the global climate is through carbon dioxide release from the burning of fossil fuels," he told Exxon's Management Committee.
A year later in 1978, one of the most seminal works on Antarctica was published by John Mercer from the Institute of Polar Studies, who concluded: "One of the warning signs that a dangerous warming trend is under way in Antarctica will be the breakup of ice shelves on both coasts of the Antarctic Peninsula, starting with the northernmost and extending gradually southward."
But Exxon ignored the warning signs and tried to discredit the science. Instead of taking responsible action, the company employed a decades-long deceitful and disingenuous climate denial campaign that has been well documented by scholars and activists alike.
The scientists and executives from Exxon deliberately followed the tobacco industry's tactics of sowing doubt about evidence. Exxon set out to exaggerate the uncertainty in the science and twist the facts.
In October 1997, decades after the company was first warned about climate change, the head of Exxon at the time, Lee "Iron Ass" Raymond, delivered a speech to the Fifteenth World Petroleum Congress in China.
As Steve Coll recalled in his book "Private Empire," Raymond "devoted thirty-three paragraphs of his seventy-eight-paragraph speech to the argument that evidence about manmade climate change was an illusion."
Months later, Exxon helped create a task-force working with the American Petroleum Institute: "Victory will be achieved when average citizens understand (recognize) uncertainties in climate science" and when public "recognition of uncertainty becomes part of "unconventional wisdom." Where Big Tobacco led, Exxon followed in promoting uncertainty.
Between 1998 and 2005, Exxon donated $16 million to numerous right-wing and libertarian think tanks to manufacture uncertainty about climate change.
In 2006, nearly three decades after Exxon was first warned about climate change, the British Royal Society wrote to Exxon asking the company to stop funding organizations which feature information "on their websites that misrepresented the science of climate change, by outright denial of the evidence that greenhouse gases are driving climate change, or by overstating the amount and significance of uncertainty in knowledge or by conveying a misleading impression of the potential impacts of anthropogenic climate change."
But Exxon has continued funding climate denial and Antarctica continues to warm.

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
