Rain falls at Greenland ice summit for first time on record

August 21, 20211328 Views

Rain fell at the highest point on the Greenland ice sheet last week for the first time on record, another worrying sign of warming for the ice sheet already melting at an increasing rate, scientists said on Friday. "That's not a healthy sign for an ice sheet," said Indrani Das, a glaciologist with Columbia University's Lamont-Doherty Earth Observatory. "Water on ice is bad. … It makes the ice sheet more prone to surface melt." Not only is water warmer than the usual snow, it's also darker -- so it absorbs more sunlight rather than reflecting it away. A satellite image shows Nuuk Fjord, Greenland July 29, 2021.

Rare summer flooding submerged Venice's famed Piazza San Marco in up to a metre of water overnight. The lagoon city is often hit by so-called "acqua alta" (high water) in autumn and winter, and devastating floods in November 2019 caused hundreds of millions of euros of damage. A couple dances in a flooded St. Mark's Square during an exceptional high water in Venice, Italy August 8, 2021. REUTERS/Manuel Silvestri Sunday night's event was less damaging, however, and couples in the square danced to piano music almost knee deep in the water, while children splashed and paddled and tourists waded through, shoes in hand. Venice's high water incidents are caused by a combination of factors exacerbated by climate change - from rising sea levels and unusually high tides to land subside...

UN Climate panel warns of a catastrophe

Earth has not been so warm since the Pliocene Epoch roughly 3 million years ago Among the many things that IPCC report released on Monday had said very categorically, one of utmost significance is that the world is running out of time. Climate change is already affecting every inhabited region across the globe with human influence contributing to many observed changes in weather and climate extremes. If the world drastically cuts emissions in the next decade, average temperatures could still rise 1.5C by 2040 and possibly 1.6C by 2060 before stabilizing.

Once-in-50-year heat waves now happening every decade

U.N. sounds clarion call over 'irreversible' climate impacts by humans The U.N. climate panel sounded a dire warning Monday, saying the world is dangerously close to runaway warming – and that humans are "unequivocally" to blame. Extreme heat waves that previously only struck once every 50 years are now expected to happen once per decade because of global warming, while downpours and droughts have also become more frequent, a UN climate science report has said. Flames rise as a wildfire burns at the village of Afidnes, north of Athens, Greece August 6, 2021. REUTERS/Costas Baltas The report found that we are already experiencing those effects of climate change, as the planet has surpassed more than 1 degree Celsius in average warming. Heat waves, droughts and torrential rains ...

Costa Rica eyes permanent ban on fossil fuels

Saving rich biodiversity and decarbonizing by 2050 are the targets Costa Rican lawmakers this week will discuss a bill to permanently ban fossil fuel exploration and extraction, a move that would prevent future governments from pivoting on the issue as the popular eco-tourism destination country aims to decarbonize by 2050. General view of the National Park Tapamti in Orosi, 80 miles (128km) of San Jose. Green trailblazer Costa Rica is drawing up plans to cut its net greenhouse gas emissions to zero before 2030, the government said on Thursday, and aims to be the first nation to offset all its carbon. REUTERS/Juan Carlos Ulate Costa Rica started efforts to ban fossil fuel exploration in 2002 under President Abel Pacheco. This ban was supposed to expire in 2014 but later extended ...

From China to Germany, floods expose climate vulnerability

Deadly floods that have upended life in both China and Germany have sent a stark reminder that climate change is making weather more extreme across the globe. At least 25 people in the central Chinese province of Henan died on Tuesday, including a dozen trapped in a city subway as waters tore through the regional capital of Zhengzhou after days of torrential rain. Coming after floods killed at least 160 people in Germany and another 31 in Belgium last week, the disaster has reinforced the message that significant changes will have to be made to prepare for similar events in future.

Marine scientist Deborah Brosnan remembers “feeling like a visitor at an amazing party” on her diving trips to a bay near the Caribbean island of Saint Barthelemy where she swam above coral reefs with nurse sharks, sea turtles and countless colorful fish. But on a return trip after Hurricane Irma ravaged the island in 2017, she dove the reef again - and was shocked by what she saw. “Everything was dead,” she recalled in an interview with Reuters. “There were no sharks, no sea turtles, no sea grass, no living coral. I felt like I lost my friends.” Marine scientist Deborah Brosnan does a research dive on a coral reef, in this undated handout in Antigua and Barbuda.

Satellite-based real-time monitoring of Himalayan glacial catchments would improve understanding of flood risk in the region and help inform an early flood warning system that could help curb disaster and save human lives, says a recent study. This should be the future strategy to reduce loss of human lives during glacial lake outburst floods (GLOF), said a study carried out by scientists from IIT Kanpur. The study carried out by Dr. Tanuj Shukla and Prof. Indra Sekhar Sen, Associate Professor from IIT Kanpur, with support from the Department of Science & Technology, Government of India, has been published in the international journal ‘Science’.

Scientists are now racing to track what’s left of the underwater seagrass plateaus Hundreds of miles from the nearest shore, ribbon-like fronds flutter in the ocean currents sweeping across an underwater mountain plateau the size of Switzerland. A remote-powered camera glides through the sunlit, turquoise waters of this corner of the western Indian Ocean, capturing rare footage of what scientists believe is the world’s largest seagrass meadow.

During some summers, as the Caribbean water temperatures climb, the luminous coral colonies of gold, green and blue that ring the island nation of Cuba give way to patches of skeletal white. The technicolor streaks of darting tropical fish flash less frequently. The rasping sounds of lobsters go quiet. While Cuba’s marine life has suffered from overfishing and pollution, there is mounting evidence that the warming of waters due to climate change may be taking a large toll as well -- both off the island’s coast and globally. A view of a coral colony on the coast of Havana, Cuba, March 28, 2021. REUTERS/Sarah Marsh Research published Monday finds that the total number of open-water species declined by about half in the 40 years up to 2010 in tropical marine zones worldwide. Duri...
