Warming temperatures threaten Greece’s prized olive oil

December 16, 2021477 Views

Months before the harvest began in November, Greek olive oil farmer Michalis Antonopoulos knew it would not be a good year. First, his trees did not fully blossom because last winter was not cold and wet enough. In the spring, temperatures soared to 38 degrees Celsius (100 Fahrenheit), damaging the flowers that were to grow into olives. Then the summer brought the worst heat wave in decades, drying up the olives and setting off wildfires that torched hundreds of thousands of trees. Standing in his grove in Kalamata, Greece's best-known olive producing region, among trees that are hundreds of years old, Antonopoulos pointed to the results: half empty branches, with small or shriveled olives, or rotting, attacked by a fruit fly. "We're witnessing phenomena and problems th...

Was US tornado outbreak related to climate change?

Tornadoes ripped through over five US stated on Friday, killing dozens. Here's a look at what's known about Friday's tornado outbreak and the role of climate change in such weather events The calendar said December but the warm moist air screamed of springtime. Add an eastbound storm front guided by a La Nina weather pattern into that mismatch and it spawned tornadoes that killed dozens over five US states. Destroyed homes and debris are seen in a heavily damaged neighborhood at dawn after tornadoes ripped through several U.S. states in Dawson Springs, Kentucky, U.S., December 12, 2021.

Hi-tech monitoring and carbon offsets for rainforests could be the big gain

A global carbon credits breakthrough at COP26 in Glasgow blew away any gloom from failing to phase out coal use, say many observers. Discussion at the UN climate conference had been dominated by soaring atmospheric carbon dioxide levels, largely from fossil fuels but exacerbated by global deforestation, notably in tropical rainforests like the Amazon’s – often called the “Lungs of the Earth”. But while COP26 failed to strike a coal deal, a carbon credit agreement could channel trillions of private sector dollars into protecting rainforests and farms, building renewable energy facilities and other projects to combat Climate Change and promote the circular economy needed to stabilise the Earth’s environment.

Collapse of ancient Liangzhu culture caused by climate change

Referred to as "China's Venice of the Stone Age", the Liangzhu excavation site in eastern China is considered one of the most significant testimonies of early Chinese advanced civilisation. More than 5000 years ago, the city already had an elaborate water management system. Until now, it has been controversial what led to the sudden collapse. Massive flooding triggered by anomalously intense monsoon rains caused the collapse, as an international team with Innsbruck geologist and climate researcher Christoph Spötl has now shown in the journal Science Advances.

Arctic Ocean started getting warmer decades earlier than we thought

The Arctic Ocean has been getting warmer since the beginning of the 20th century – decades earlier than records suggest – due to warmer water flowing into the delicate polar ecosystem from the Atlantic Ocean. An international group of researchers reconstructed the recent history of ocean warming at the gateway to the Arctic Ocean in a region called the Fram Strait, between Greenland and Svalbard. FILE PHOTO: Icebergs are seen at the mouth of the Jakobshavn ice fjord near Ilulissat, Greenland, September 16, 2021. REUTERS/Hannibal Hanschke Using the chemical signatures found in marine microorganisms, the researchers found that the Arctic Ocean began warming rapidly at the beginning of the last century as warmer and saltier waters flowed in from the Atlantic – a phenomenon called At...

Antarctic ice-sheet destabilized within a decade

A new Study provides critical insights into ice mass loss in Antarctica After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern Ocean. A new data-model study led by the University of Bonn (Germany) now shows that it took only a decade to initiate this tipping point in the climate system, and that ice mass loss then continued for many centuries. Accompanying modeling studies suggest that today's accelerating Antarctic ice mass loss also represents such a tipping point, which could lead to irreversible and long-lasting ice retreat and global sea level rise. The study has now been published in the journal Nature Communications. To understand what the consequences of current and futu...

South Korea’s beaches face threat from development, rising seas

For years, the crystalline blue water and soft sand of South Korea's Sacheonjin beach has been favoured by surfers and vacationers seeking a quieter experience than more crowded options on the east coast. But Choi Jong-min, who runs a guest house Sacheonjin, was shocked when high waves washed away major portions of the beach this year, including during a typhoon in August. "The waters have never been this close and the waves never so high for the past 12 years," Choi said at his guest house, looking out the window. "This place was famous for calm waves, but look, they're widely breaking now." Understructures are exposed at Jumunjin beach damaged by erosion, in Gangneung, South Korea, February 12, 2020.

Canada flood shows how climate change could fuel atmospheric river storms

Atmospheric rivers of the kind that drenched California and flooded British Columbia in recent weeks will become larger -- and possibly more destructive -- because of climate change, scientists said. Columns in the atmosphere hundreds of miles long carry water vapor over oceans from the tropics to more temperate regions in amounts more than double the flow of the Amazon River, according to the American Meteorological Society.

UN climate agreement clinched after late drama over coal

U.N. climate talks ended Saturday with a deal that for the first time targeted fossil fuels as the key driver of global warming, even as coal-reliant countries lobbed last-minute objections. While the agreement won applause for keeping alive the hope of capping global warming at 1.5 degrees Celsius, many of the nearly 200 national delegations wished they’d come away with more. “If it’s a good negotiation, all the parties are uncomfortable,” U.S. climate envoy John Kerry said in the final meeting to approve the Glasgow Climate Pact. “And this has been, I think, a good negotiation.” COP26 President Alok Sharma gestures as he receives applause during the UN Climate Change Conference (COP26) in Glasgow, Scotland, Britain November 13, 2021.

International aviation climate ambition reflects airlines’ net-zero goal

The International Air Transport Association (IATA) welcomed the commitments towards strengthening climate action made at COP26, and called on the global efforts to decarbonize aviation to be supported with practical, effective government policies. Management of international aviation’s climate commitments sits outside of the COP process and is the responsibility of the International Civil Aviation Organization (ICAO). Nevertheless, airlines at the 77th IATA AGM in Boston, October, agreed to achieve net-zero carbon emissions by 2050, in line with the stretch Paris agreement target to keep global warming to 1.5 degrees. “Airlines are on the pathway to net-zero carbon emissions, in line with the Paris agreement. We all want the freedom to fly sustainably. Reaching net-zero emission...
