Venice is the Mediterranean World Heritage Site currently most at risk from flooding due to sea level rise, according to a recent study, and the city even has elevated sidewalks ready in case of high tides, but Monday's waters rose higher than the emergency sidewalks. The tide surpassed 5 feet, 3 inches, making it the highest recorded since 2008 and potentially the highest recorded since 1979, CNN reported.

As sea levels rise, high-tide flooding is becoming a growing problem in many parts of the globe, including cities on the U.S. East Coast. Now, new research shows that as these waters recede, they carry toxic pollutants and excess nutrients into rivers, bays, and oceans

Tide Professional Coldwater Laundry System enables hotel facilities to reduce energy needed to heat the water in a commercial washer by as much as 75 percent and to reduce water used in a commercial washer by up to 40 percent, says manufacturer P&G Professional, a division of Procter & Gamble

Cleantech company Nova Innovation has reportedly built the world's first fully operational, commercial, grid-connected array of underwater turbines that generate power from oceanic tides. The array is located northeast of Scotland in the Shetland Islands.

Sea level rise is caused primarily by two factors related to global warming: the added water from melting land ice and the expansion of sea water as it warms. The first chart tracks the change in sea level since 1993 as observed by satellites. The second chart, derived from coastal tide gauge data, shows how much sea level changed from about 1870 to 2000.

In 1900, an estimated 100,000 tigers roamed free on our planet. Yet within a hundred years, that number plummeted by more than 95 percent - the result of rampant poaching and widespread habitat loss. But it seems the tide may finally be turning for the majestic cat. On Sunday, the World Wildlife Fund (WWF) announced that wild tiger numbers were on the rise for the first time in over a century.

Ocean Conservancy on Wednesday released a report that proposes a four-point solution to cutting ocean plastic waste by 45 percent by 2025 with the ultimate goal of eradicating the issue by 2035. Stemming the Tide: Land-based strategies for a plastic-free ocean is a first-of-its-kind, solutions-oriented report in partnership with the McKinsey Center for Business and Environment that outlines specific land-based solutions for plastic waste in the ocean.

Procter & Gamble has set a goal of obtaining 30% of its global electricity from renewable sources by 2020. One way the company will do that is by acquiring output from a wind farm to be built in Cooke County, Texas, in partnership with EDF Renewable Energy. "Wind not only emits zero greenhouse gas emissions, but also delivers long-term energy price stability," said EDF chief executive Tristan Grimbert. 

At the University of Miami's Department of Atmospheric Sciences, Brian McNoldy and other researchers have been accumulating sea level data from Virginia Key (a small island just south of Miami Beach) since 1996. Over those nineteen years, sea levels around the Miami coast have already gone up 3.7 inches.
