Shocking Polar Bear Photos Show Stark Reality of Climate Change
Langenberger posted on her Facebook:
I see the summers being so pleasant (and warm) as never before. I see the glaciers calving, retreating dozens to hundreds of metres every year. I see the pack ice disappearing in record speed. Yes, I have seen bears in good shape—but I have also seen dead and starving polar bears. Bears walking on the shores, looking for food, bears trying to hunt reindeer, eating bird's eggs, moss and seaweed. And I realized that the fat bears are nearly exclusively males which stay on the pack ice all year long. The females, on the other hand, which den on land to give birth to their young, are often slim. With the pack ice retreating further and further north every year, they tend to be stuck on land where there's not much food. In the first year, they lose their first cub. In the second year, they lose their second (and last) cub. Only once I have seen a mother with a nearly independent cub. Only few times I have seen beautifully fat mothers with beautifully fat young. Many times I have seen horribly thin bears, and those were exclusively females—like this one here. A mere skeleton, hurt on her front leg, possibly by a desperate attempt to hunt a walrus while she was stuck on land.
Experts claim the Svalbard population is stable, even rising. Well, here comes my question: how can a population be stable if it consists of less and less females and cubs? How can a population be doing good if most bear will score a body index of two to three out of five? Only once I have seen a bear getting a big fat five, but several times I have seen dead bears and bears like this one: a mere one on the scale, doomed to death.
And while some, such as Iain Stirling from the University of Alberta, have cautioned against using this one photo as proof that all polar bears are starving in a warmer world, Langenberger is not the only one to sound the alarm.
"You have to be a little bit careful about drawing conclusions immediately," Stirling told Mashable. "[The bear] may be starving, but it may just be old. A difficulty hunting could be involved." Stirling noted that the bear appears to have an injury to one of its hind legs, which could have played a role in its weight loss. "I don't think you can tie that one to starvation because of lack of sea ice."
Still, others such as National Geographic photographer Paul Nicklen, who has been to the Arctic on multiple occasions, was struck in a recent visit by the rapidly dwindling sea ice and the number of dead polar bears—something he had never seen before.
Last summer I traveled with a group of friends to Svalbard, Norway in search of polar bears. We went to my favorite spot where I have always been able to find bears roaming around on sea ice throughout the summer. On this occasion, however, we didn't find any sea ice and we never found any bears alive. We did find two dead bears in this location and other groups found more dead bears. These bears were so skinny, they appeared to have died of starvation, as in the absence of sea ice, they were not able to hunt seals. In all of my years of growing up in the Arctic and later, working as a biologist, I had never found a dead polar bear. It is now becoming much more common. Through @sea_legacy and @natgeo we will continue to shine a light on our changing planet to convince the unconvinced.

And all of this anecdotal evidence is supported by scientific data. The International Union for Conservation of Nature and Natural Resources (IUCN) currently lists polar bears as "vulnerable"—one step above "endangered"—because it's believed that their numbers have been reduced by more than 30 percent in the last 45 years.
"Global climate change posses a substantial threat to the habitat of polar bears," says the IUCN. "Recent modeling of the trends for sea ice extent, thickness and timing of coverage predicts dramatic reductions in sea ice coverage over the next 50-100 years."

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>
