Hurricane Ian dumped 10% more rain due to climate change: research

Paris, France | AFP | by Kelly MACNAMARA Climate change increased the rainfall from Hurricane Ian by more than 10 percent, according to a new quick-fire analysis, as one of the most powerful storms ever to hit the United States devastated parts of Florida. Ian “could be the deadliest hurricane in Florida history”, President Joe Biden said after the storm brought ferocious winds, turned streets into churning rivers that swept away homes and left an […]

Climate on track to devastate world’s poorest economies: study

by Marlowe HOOD GLASGOW, United Kingdom (AFP) — The 65 most vulnerable nations will see GDP drop 20 percent on average by 2050 and 64 percent by 2100 if the world heats up 2.9 degrees Celsius, according to a report released Monday at the COP26 climate talks in Glasgow. Even if global temperature rises are capped at 1.5C, in keeping with the most ambitious Paris Agreement goal, the same countries would take a GDP hit […]

Vaccines prevent severe Covid, even from Delta: study

PARIS, France (AFP) — Vaccination is highly effective at preventing severe cases of Covid-19, even against the Delta variant, a vast study in France has shown. The research published Monday — focusing on prevention of severe Covid and death, not infection — looked at 22 million people over 50 and found those who had received jabs were 90 percent less likely to be hospitalised or die. The results confirm observations from the US, the UK […]

Rapid Arctic warming triggers extreme winter events in US: study

by Lucie AUBOURG Agence France-Presse WASHINGTON D.C., United States (AFP) — Rapid warming of the Arctic is likely a key driver of extreme winter weather in the United States, according to a new study that addresses a longstanding apparent contradiction in climate science and could explain events like February’s cold snap in Texas. The paper, published in the journal Science, used observational data and modeling to establish a link between planetary warming linked to human […]

Covid symptoms last a year for many patients: study

PARIS, France (AFP) — Fatigue and shortness of breath still afflict many patients a year after their hospitalization for Covid-19, according to a new Chinese study calling for a better understanding of the pandemic’s long-term health effects. Around half of the patients discharged from hospital for Covid still suffer from at least one persistent symptom — most often fatigue or muscle weakness — after 12 months, said the study published in British medical journal The […]

Past ice melts may have caused seas to rise 10 times faster than today: study

LONDON, United Kingdom (AFP) — Ice sheet melting at the end of the last ice age may have caused sea levels to rise at 10 times the current rate, a study published Thursday by a team led by scientists from Britain’s Durham University said. Based on geological records, the researchers estimate that oceans worldwide rose 3.6 metres per century over a 500-year period some 14,600 years ago. The findings raise a red flag about the […]

Study shows number of anti-Asian racism reports in Canada higher than US per Asian capita

  (Eagle News) — A study in Canada showed that the number of anti-Asian racism reports in the country is actually higher than in the United States, when measured on an Asian per capita basis. In May 2020, Statistics Canada released a report to show how the COVID-19 pandemic has affected the perception of visible minority groups regarding safety within Canada. The report showed that visible minority participants that perceived race-based attacks and harassment was […]

Children have stronger antibody response to Covid: study

WASHINGTON, United States (AFP) — Children who are 10 and younger produce more antibodies in response to coronavirus infection than adolescents and adults, a study showed Monday. The authors of the paper, which appeared in JAMA Network Open, said the finding helped illuminate why children are less susceptible to severe Covid-19 than adults — though this is still an area of very active research and many factors are believed to be at play. A team […]

Asymptomatic virus sufferers lose antibodies sooner: study

LONDON, United Kingdom (AFP) — Asymptomatic coronavirus sufferers appear to lose detectable antibodies sooner than people who have exhibited Covid-19 symptoms, according to one of the biggest studies of its kind in Britain published on Tuesday. The findings by Imperial College London and market research firm Ipsos Mori also suggest the loss of antibodies was slower in 18–24 year-olds compared to those aged 75 and over. Overall, samples from hundreds of thousands of people across […]

‘Test-&-trace’ crucial but won’t beat coronavirus alone: study

by Marlowe HOOD PARIS, France (AFP) — Testing for COVID-19 and tracing the prior contacts of those found to be infected are crucial measures for slowing the disease’s spread, but inadequate unless combined with other measures, researchers said Wednesday. By itself, the test-and-trace approach can reduce the virus’ reproduction rate, or R number, by 26 percent, they reported in The Lancet Infectious Diseases, using mathematical models to examine data from previously published studies. The reproduction […]

Asymptomatic coronavirus carriers have high viral loads: study

WASHINGTON, United States (AFP) — People who are infected with the coronavirus carry similar levels of the pathogen in their nose, throat and lungs whether they have symptoms or not, a new study from South Korea showed Thursday. The paper, published in JAMA Internal Medicine, is an important biological line of evidence in support of the idea that asymptomatic carriers can spread COVID-19. Until now, experts have relied on inferring asymptomatic spread when people contract […]

Intensive farming heightens pandemic risk: study

by Patrick GALEY PARIS, France (AFP) — Intensive farming makes future pandemics such as COVID-19 more likely as wild animals carrying diseases known to infect humans are forced into increasingly close contact with us, research showed Wednesday. Writing in the journal Nature, a team of researchers from University College London warned that animal pathogens are increasingly likely to make the leap to humans as land use changes benefit animal hosts. The United Nations estimates that […]
