President Obama Tweets First Blue Marble Photo in 43 Years
NASA's new Deep Space Climate Observatory (DSCOVR) satellite has released a stunning, new Blue Marble photo for the first time in four decades, prompting President Obama to tweet a gentle reminder "that we need to protect the only planet we have."
— President Obama (@POTUS) July 20, 2015
The image above was taken on July 6 literally one million miles away and is the first Blue Marble photo of our planet since 1972, when the now-iconic photo of our glistening world was snapped by the American crew of the Apollo 17 spacecraft.
"Turns out," as NASA astronaut Scott Kelly wrote on the White House's Medium page, "It’s quite tricky to take a good photo of the entire Earth." Other images you've seen of Earth are composites assembled from multiple different shots.

EcoWatch readers know that it's more important than ever to preserve our environment from the dire effects of climate change, and President Obama has spoken out on this issue many times before.
At his Earth Day speech delivered at the Everglades National Park this past April, the commander-in-chief emphasized this message clearly:
"This is a problem now. It has serious implications for the way we live right now. Stronger storms. Deeper droughts. Longer wildfire seasons. The world’s top climate scientists are warning that a changing climate already affects the air that our children are breathing."
At the end of his speech, Obama concluded that we must all be planetary stewards to ensure the safety of future generations:
"We are blessed with the most beautiful God-given landscape in the world. It’s an incredible bounty that’s been given to us. But we’ve got to be good stewards for it. We have to take care of it. We only get to enjoy things like our amazing national parks because great Americans like Teddy Roosevelt and Marjory Stoneman Douglas and a whole bunch of ordinary folks whose name aren’t in the history books, they fought to protect our national inheritance. And now it’s our turn to ensure that this remains the birthright of all Americans for generations to come. So many people here are active in your communities, doing what’s needed. The young people who are here, the next generation, they’re way ahead of us in understanding how important this is. Let’s make sure we don’t disappoint them. Let’s stand up and do what’s right before it’s too late."
Following POTUS' tweet, plenty fellow Twitter users sent responses. Here are some of my favorites:
Agreed @POTUS, even more justification to push for a new #climate #deal in #Paris. @NASA https://t.co/bewwvHfi7r — NN Themvu Projects (@themvup) July 21, 2015

@POTUS @NASA Absolutely. So let's put a stop to #TPP before it breaks things even more. — Jack Phoenix (@BohemianPaladin) July 21, 2015
@POTUS @NASA To protect the only planet we have takes real leadership and new ideas. More energy efficient homes, appliances, cars, etc !!!!

The White House's official Twitter also chimed in that DSCOVR will release several more Blue Marbles in the very near future:
The blue marble. It's our home. And soon, @NASA's #DSCOVR will be able to take full snapshots of it every few hours. http://t.co/KLWb0EG992

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.
Comparing rime ice and glaze ice shows how each changes the texture of the blade. Gao, Liu and Hu, 2021, CC BY-ND
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>
