Climate change is killing the world’s coral reefs as oceans warm

October 6, 2021466 Views

Study shows 14% of the world's coral on reefs was already lost between 2009 and 2018 The world's coral reefs are under attack by climate change and more will disappear if oceans keep warming, according to a report released Tuesday. The study by the Global Coral Reef Monitoring Network (GCRMN), a U.N.-supported global data network, showed that 14% of the world's coral on reefs was already lost between 2009 and 2018, equal to about 11,700 square kilometers, an area 2.5 times the size of Grand Canyon National Park.

The International Air Transport Association (IATA) 77th Annual General Meeting has approved a resolution for the global air transport industry to achieve net-zero carbon emissions by 2050. This commitment will align with the Paris Agreement goal for global warming not to exceed 1.5°C. “The world’s airlines have taken a momentous decision to ensure that flying is sustainable. The post-COVID-19 re-connect will be on a clear path towards net zero. That will ensure the freedom of future generations to sustainably explore, learn, trade, build markets, appreciate cultures and connect with people the world over. With the collective efforts of the entire value chain and supportive government policies, aviation will achieve net zero emissions by 2050,” said Willie Walsh, IATA’s Director General...

Italy’s ‘Smart Bay’ seeks to tackle Mediterranean climate change

On Italy's Ligurian coast, biologists and environmentalists are working to tackle the effects of climate change in the Mediterranean with help from a so-called "Smart Bay". Marine biologists fear the Mediterranean is becoming hotter and more acidic, which would affect the habitat of many native species and also lead to violent changes in weather systems such as more frequent tornadoes. The Santa Teresa Smart Bay, in an area on the northwestern coast noted for tourism and diving, is Italy's first underwater "living" laboratory where scientists use aquatic invertebrate animals known as bryozoans and other organisms as live sensors. Spirographs and mussels are pictured underwater in the Smart Bay of Santa Teresa, in Lerici, Italy, September 15, 2021. REUTERS/Flavio Lo Scalzo. ...

WTTC also announces social and environmental indicators at Climate Week The World Travel & Tourism Council (WTTC) has launched a Net Zero Roadmap for the Travel & Tourism sector to support the industry in combatting climate change during its virtual climate week event. It also announced the launch of ground-breaking social and environmental research data. The first time such data will be produced across the whole sector, building on WTTC’s annual high-anticipated Economic Impact Report (EIR). These vital pieces of work represent WTTC’s biggest deliverables in the sector’s drive towards net zero by 2050. The powerful initiative is being run in collaboration with the United Nations Environment Programme (UNEP) and professional services and consulting experts, A...

The Glasgow Declaration signatories get together to galvanise efforts In preparation for COP26, two information sessions were held on the Glasgow Declaration on Climate Action in Tourism. The Declaration, developed by a collaborative group of leading organizations, is an urgent call for all stakeholders to commit to a decade of climate action in tourism. The signatories of the Glasgow Declaration on Climate Action in Tourism are committing to act now and accelerate climate action to cut global tourism emissions by at least a half over the next decade and reach Net Zero emissions as soon as possible before 2050. In particular, each signatory will commit to deliver a concrete climate action plan, or updated plan, within 12 months of signing. Plans will be aligned with the proposed pat...

Rain falls at Greenland ice summit for first time on record

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.

Zombie Siberian wildfires send its smoke to North Pole for the first time

For the first time in recorded history, hazy smoke from raging wildfires in the Arctic has reached the North Pole, and NASA satellites have the images to prove it. On Aug. 6, the space agency's MODIS, an imaging sensor on the Aqua satellite, captured true-color images of what NASA called a "vast, thick, and acrid blanket of smoke" that clouded the North Pole. The smoke originated from enormous blazes in the Siberian region of northern Russia. According to China's Xinhua news agency, the Mongolian capital city of Ulaanbaatar was blanketed in "white smoke," NPR reported. The republic of Yakutia – home to Oymyakon, the coldest inhabited place on Earth – has also been shrouded in smoke, as captured by MODIS images on Aug. 8. A vast, thick, and acrid blanket of smoke emitted from hund...

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.

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.
