India’s Sixth-Largest City Is Almost Out of Water
In Chennai, home to nearly 4.6 million people, four major reservoirs are running dry. The monsoon has been delayed, and rainfall has fallen 99 percent in the region from June 1 to 19, while temperatures have reached 104 degrees Fahrenheit.
"We are facing one of the worst water shortages in recent years. The water situation has been very bad for the last month. And it will be worse if there is no rain in the coming days," Chennai resident Rajasimhan told BBC News. "There is no water through the taps."

A weaker monsoon season in South Asia is one of the predicted outcomes of the climate crisis, Al Jazeera reported. The entire region has seen below average rainfall for the last five years. In southern Tamil Nadu, the state where Chennai is located, monsoon rains were 62 percent below normal last year. They were also weak in 2017, leading to a depletion of groundwater and the drying out of four major lakes: Chembarambakkam, Poondi, Red Hills and Cholavaram. Dramatic satellite images from Maxar show the depletion of Lake Puzhal, the city's largest reservoir, between June of 2018 and 2019, CNN reported.

State fisheries minister D Jayakumar told Al Jazeera that the government was moving approximately 400 water tankers on 9,000 trips across the city to help the thirsty population.
But the water is not coming fast enough for some. At least 550 people were arrested Wednesday at a demonstration outside the municipal building of Coimbatore, CNN reported. They held empty water containers and accused the government of mismanagement.
There have also been reports of fighting over water and of water trucks being hijacked, CNN reported.
There is some temporary relief in store for Chennai. There were reports of rain on Thursday, but the Indian Meteorological Department told CNN it would not relieve the drought.
"Unfortunately this is forecast to be light to moderate rain and the reservoirs are almost dry. So, this won't help in replenishment but will just give respite from the heat," the department said. "The proper rain to fill up the reservoirs isn't expected until November."

Due to a combination of climate change and mismanagement, India overall is facing the worst water crisis in its history. A report from a government think tank released in 2018 found that 200,000 Indians die each year from lack of access to water and demand would double supply by 2030.

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>

Tamara Lindeman certainly doesn't seem particularly anxious, or grief stricken, or angry. In fact, in a recent Zoom conversation, the Toronto-based singer-songwriter (who records and performs under the name The Weather Station) comes across as friendly, thoughtful, and a little shy.

Walking to work or to the store is better for the climate than driving, so climate advocates encourage people to leave their cars at home when possible.
An independent market monitor says ERCOT, the Texas grid operator, left wholesale electricity prices at the legal maximum for two days longer than necessary, and overcharged power companies $16 billion in the process during the winter storm that caused massive grid and gas system failures and left more than 4 million Texans without electricity.
