World could breach 1.5C warming threshold in 7 years: study

By Kelly MACNAMARA PARIS, Dec 5, 2023 (AFP) – The world may cross the crucial 1.5C global warming threshold in seven years as fossil fuel CO2 emissions continue to rise, scientists warned Tuesday, urging countries at the COP28 talks to “act now” on coal, oil and gas pollution. Battle lines are being drawn over the future of fossil fuels at the UN climate summit in Dubai, with big polluters trying to see off calls for […]

Reversing warming may stop Greenland ice sheet collapse: study

Breaching the global warming limits of the world’s climate goals could see the melting of Greenland’s ice sheet add more than a metre to rising sea levels, according to new research on Wednesday. But the study by an international team of researchers found there would still be hope to prevent a collapse of the ice sheet — if warming is reversed and brought back to the safer level. The melting of Greenland’s vast ice sheet […]

The ozone layer: fragile protection for the Earth

The ozone layer that shields life on Earth from deadly solar radiation is on track to recover within decades, but controversial geoengineering schemes to blunt global warming could reverse that progress, a major scientific assessment warned Monday. The ozone layer is situated in the stratosphere at 15 kilometres altitude and protects Earth from the Sun’s ultra-violet radiation. Without it there’d be no plants, no animals… none of us would be here! A natural shield comes […]

What is the link between winter storms and global warming?

WASHINGTON, United States (AFP) – The world is getting warmer, winters included. The United States, however, has experienced severe winter storms in recent years, and experts are taking a closer look at the link between these extreme cold events and climate change. While the link between global warming and heat waves is very direct, the behavior of winter storms is governed by complex atmospheric dynamics that are more difficult to study. Even so, “there are certain […]

Swiss glaciers shrink in half since 1931: study

  by Nina LARSON Agence France Presse GENEVA, Switzerland (AFP) — Swiss glaciers have shed half their volume since 1931, Swiss researchers said Monday, following the first reconstruction of the country’s ice loss in the 20th century. Rapid glacier melt in the Alps and elsewhere, which scientists say is driven by climate change, has been increasingly closely monitored since the early 2000s. However, until now there has been little insight into how glaciers changed prior […]

Climate deniers use past heat records to sow doubt online

BARCELONA, Spain (AFP) – With Europe gripped by successive heatwaves, climate-change deniers are spreading scepticism by publishing data on social media on extreme temperatures allegedly recorded decades ago to imply scientists are exaggerating global warming. But experts say the figures cited from the past are often incorrect or taken out of context — and even if accurate do not change the fact that heatwaves are becoming more frequent and intense. The posts typically include heat […]

Thaw and redraw: melting glacier moves Italian-Swiss border

  by Nicolas CAMUT Agence France Presse Way up in the snowy Alps, the border between Switzerland and Italy has shifted due to a melting glacier, putting the location of an Italian mountain lodge in dispute. The borderline runs along a drainage divide — the point at which meltwater will run down either side of the mountain towards one country or the other. But the Theodul Glacier’s retreat means the watershed has crept towards the […]

Climate change’s fingerprints on ever hotter heatwaves

    PARIS, France (AFP) — Hotter, longer, more frequent. Heatwaves such as the one currently roasting much of Europe, or the record-shattering hot spell endured by India and Pakistan in March, are an unmistakable sign of climate change, experts said Monday. – Humans to blame – “Every heatwave that we are experiencing today has been made hotter and more frequent because of human induced climate change,” said Friederike Otto, senior lecturer at Imperial College […]

Japan swelters as heatwave prompts power crunch warning

  TOKYO, Japan (AFP) — Japan’s government warned Monday of a power crunch as extreme heat hits the country, with temperature records toppling and Tokyo’s rainy season declared over at the earliest date on record. Residents in and around the capital have been asked to conserve energy, particularly in the early evening. Temperatures of 35 degrees Celsius (95 degrees Fahrenheit) are forecast in Tokyo throughout Monday, and the mercury is not expected to drop below […]

South Asia pummelled by heatwave that hits 50C in Pakistan

  by Ashraf KHAN Agence France Presse JACOBABAD, Pakistan (AFP) — South Asia was in the grip of an extreme heatwave on Friday, with parts of Pakistan reaching a temperature of 50 degrees Celsius as officials warned of acute water shortages and a health threat. Swathes of Pakistan and neighbouring India have been smothered by high temperatures since April in extreme weather that the World Meteorological Organization has warned is consistent with climate change. On […]

India, Pakistan must brace for even worse heatwaves

  by Marlowe HOOD Agence France Presse The devastating heatwave that gripped India and Pakistan over the last two months is unprecedented, but worse — perhaps far worse — is on the horizon as climate change continues apace, top climate scientists told AFP. Even without additional global warming South Asia is, statistically speaking, ripe for a “big one” in the same way that California is said to be overdue for a major earthquake, according to […]

New Zealand sea level rising more quickly than forecast: data

  WELLINGTON, New Zealand (AFP) — The sea level is rising twice as fast as previously forecast around parts of New Zealand, according to research published Monday, putting the country’s two largest cities at risk decades earlier than expected. Government-backed data amassed from around the country’s coastline found some areas are already sinking three to four millimetres per year, speeding up a long-expected threat. The projections, labelled “a bit terrifying” by one expert, are the […]
