2023 to be hottest year on record

December 6, 2023558 Views

November is the sixth straight month to set a heat record The last half year has truly been shocking, scientists are running out of adjectives to describe this European Union scientists said on Wednesday that 2023 would be the warmest year on record, as global mean temperature for the first 11 months of the year hit the highest level on record, 1.46 degrees Celsius (2.63 degrees Fahrenheit) above the 1850-1900 average. For the sixth month in a row, Earth set a new monthly record for heat, and also added the hottest autumn to the litany of record-breaking heat this year, the European climate agency calculated. And with only one month left, 2023 is on the way to smashing the record for hottest year. FILE PHOTO: Manuel Flores walks on a dry area that shows the drop in the level...

Peru lost more than half of its glacier surface in just over half a century

Peru has lost more than half of its glacier surface in the last six decades, and 175 glaciers became extinct due to climate change between 2016 and 2020, Peruvian scientists from the state agency that studies glaciers said Wednesday. “In 58 years, 56.22% of the glacial coverage recorded in 1962 has been lost,” said Mayra Mejía, an official with Peru’s National Institute of Research of Mountain Glaciers and Ecosystems, or Inaigem. The factor that causes the greatest impact is the increase in the average global temperature, causing an accelerated retreat of glaciers, especially those in tropical areas, Jesús Gómez, director of glacier research at Inaigem, told The Associated Press. The South American country has 1,050 square kilometers (405 square miles) of glacial coverage lef...

World’s largest iceberg breaks free, heads toward Southern Ocean

The world's largest iceberg is on the move for the first time in more than three decades, scientists said on Friday. At almost 4,000 square km (1,500 square miles), the Antarctic iceberg called A23a is roughly three times the size of New York City. Since calving off West Antarctica's Filchner-Ronne Ice Shelf in 1986, the iceberg — which once hosted a Soviet research station — has largely been stranded after its base became stuck on the floor of the Weddell Sea. Not anymore. Recent satellite images reveal that the berg, weighing nearly a trillion metric tonnes, is now drifting quickly past the northern tip of the Antarctic Peninsula, aided by strong winds and currents.

Climate on track to warm by nearly 3C without aggressive actions

UN report says world is racing to well past warming limit as carbon emissions rise Countries' current emissions pledges to limit climate change would still put the world on track to warm by nearly 3 degrees Celsius this century, according to a United Nations analysis released Monday. The annual Emissions Gap report, which assesses countries' promises to tackle climate change compared with what is needed, finds the world faces between 2.5C (4.5F) and 2.9C (5.2F) of warming above preindustrial levels if governments do not boost climate action. This year Earth got a taste of what’s to come, said the report, which sets the table for international climate talks later this month. At 3C of warming, scientists predict the world could pass several catastrophic points of no return, from...

Hottest temperature our planet has experienced in 125,000 years

Last 12 months on Earth were the hottest ever recorded, analysis finds The last 12 months were the hottest Earth has ever recorded, according to a new report by Climate Central, a nonprofit science research group. The peer-reviewed report says burning gasoline, coal, natural gas and other fossil fuels that release planet-warming gases like carbon dioxide, and other human activities, caused the unnatural warming from November 2022 to October 2023. Over the course of the year, 7.3 billion people, or 90% of humanity, endured at least 10 days of high temperatures that were made at least three times more likely because of climate change.

Belgium’s traditional horseback fishers see climate change in their nets

On a crisp, wintry day on Belgium's far-western coast, Gunther Vanbleu rides his draft horse down the sandy beach and into the shallow waters. As the bright yellow of Vanbleu's anorak stands out against the waves, under the water, his draft horse - characterized by its powerful hindquarters - pulls a chain along the sand, causing a vibration that sends shrimp jumping into an outstretched net. The coastal village of Oostduinkerke is the last place in the world where horseback shrimp fishing is still practiced - today as a UNESCO-recognised centuries-old tradition rather than a commercial enterprise. FILE PHOTO: Gunther Vanbleu, 49, a Belgian shrimps fisherman with 10 years of experience, rides his carthorse named Martha to haul a net out of the sea to catch shrimps during low tide...

A key part of Antarctica is doomed to slow collapse

Study says, nothing can be done even with carbon emissions cuts No matter how much the world cuts back on carbon emissions, a key and sizable chunk of Antarctica is essentially doomed to an “unavoidable” melt, a new study found. Though the full melt will take hundreds of years, slowly adding nearly 6 feet (1.8 meters) to sea levels, it will be enough to reshape where and how people live in the future, the study’s lead author said. Researchers used computer simulations to calculate future melting of protective ice shelves jutting over Antarctica’s Amundsen Sea in western Antarctica. The study in Monday’s journal Nature Climate Change found even if future warming was limited to just a few tenths of a degree more – an international goal that many scientists say is unlikely to be met...

Greenland’s massive ice sheet is melting — here’s how to save it

The ice sheet could experience runaway melting if the world overshoots climate targets, but even then quick action could stabilize it Greenland’s massive ice sheet, which is thawing because of human-induced climate change, could be saved from complete meltdown even if global temperatures soar past key international targets, a study suggests. But rescuing the ice in these conditions would require huge future cuts in atmospheric greenhouse-gas levels — and would not prevent the ice sheet from melting enough to cause up to several metres of sea-level rise. Melt water courses across the Greenland ice sheet, the largest ice mass in the Northern Hemisphere.

Amazon River falls to lowest in over a century amid Brazil drought

The Amazon River fell to its lowest level in over a century on Monday at the heart of the Brazilian rainforest as a record drought upends the lives of hundreds of thousands of people and damages the jungle ecosystem. Rapidly drying tributaries to the mighty Amazon have left boats stranded, cutting off food and water supplies to remote villages, while high water temperatures are suspected of killing more than 100 endangered river dolphins. Boats and houseboats are seen stranded in a dry area of the Igarape do Taruma stream which flows into the Rio Negro river, as the water level at a major river port in Brazil's Amazon rainforest hit its lowest point in at least 121 years, in Manaus, Brazil, October 16.

Whales, dolphins in American waters are losing food and habitat to climate change

Whales, dolphins and seals living in U.S. waters face major threats from warming ocean temperatures, rising sea levels and decreasing sea ice volumes associated with climate change, according to a first-of-its-kind assessment. Researchers with the National Oceanic and Atmospheric Administration examined more than 100 stocks of American marine mammal species and found more than 70% of those stocks are vulnerable to threats, such as loss of habitat and food, due to the consequences of warming waters. The impacts also include loss of dissolved oxygen and changes to ocean chemistry. FILE PHOTO: A harbor seal surfaces in Casco Bay on July 30, 2020, off Portland, Maine. (AP Photo/Robert F.
