Earth sets another heat record in January, expectations of cooler 2025

The world warmed to yet another monthly heat record in January, despite an abnormally chilly United States, a cooling La Nina and predictions of a slightly less hot 2025, according to the European climate service Copernicus. The surprising January heat record coincides with a new study by a climate science heavyweight, former top NASA scientist James Hansen, and others arguing that global warming is accelerating. It's a claim that's dividing the research community. January 2025 globally was 0.09 degrees Celsius (0.16 degrees Fahrenheit) warmer than January 2024, the previous hottest January, and was 1.75 degrees Celsius (3.15 degrees Fahrenheit) warmer than it was before industrial times, Copernicus calculated. It was the 18th month of the last 19 that the world hit or passed the internationally agreed upon warming limit of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above pre-industrial times. Scientists won't regard the limit as breached unless and until global temperatures stay

High levels of heat found to affect foetuses, infants up to age 2: Study

Exposure to high levels of heat could affect growth of foetuses in the womb and infants up to two years of age, an analysis of over 600 pregnancies in the west African country of The Gambia has suggested. For every degree Celsius rise in average daily heat in the first trimester of pregnancy, the weight of a baby at birth corresponding to gestation period was found to be lowered, according to the findings published in The Lancet Planetary Health journal. One experiences heat stress when their body's ability to regulate temperature is compromised. The researchers, led by those at the London School of Hygiene and Tropical Medicine (LSHTM), UK, followed a total of 668 infants, about half of whom were girls and half boys, for their first 1,000 days of life. At birth, 66 infants (10 per cent) were found to weigh under 2.5 kilograms, described as a low birth weight by the researchers. About a third of the infants studied (218) were found to be small for gestational age, while nine infants

Earth sets new record for hottest summer, raising global heat concerns

Summer 2024 sweltered to Earth's hottest on record, making it even more likely that this year will end up as the warmest humanity has measured, European climate service Copernicus reported Friday. And if this sounds familiar, that's because the records the globe shattered were set just last year as human-caused climate change, with a temporary boost from an El Nino, keeps dialling up temperatures and extreme weather, scientists said. The northern meteorological summer June, July and August averaged 16.8 degrees Celsius (62.24 degrees Fahrenheit), according to Copernicus. That's 0.03 degrees Celsius (0.05 degrees Fahrenheit) warmer than the old record in 2023. Copernicus records go back to 1940, but American, British and Japanese records, which start in the mid-19th century, show the last decade has been the hottest since regular measurements were taken and likely in about 120,000 years, according to some scientists. The Augusts of both 2024 and 2023 tied for the hottest Augusts ..

Extreme heat endangering children in West, Central Africa, says UNICEF

Children in West and Central Africa are increasingly exposed to extreme heat, which further endangers their health, according to a new report by UNICEF. The frequency of heatwaves in the region has more than quadrupled since the 1960s, according to the report published on Wednesday. West Africa experienced an unprecedented heat wave earlier this year that led to a surge in deaths. One hospital in Mali reported 102 deaths in the first four days of April, compared to 130 deaths in the entire month of April last year. It's unknown how many of the fatalities were due to the extreme weather as such data cannot be made public under the regulations imposed by the country's military rulers. The extreme heat is creating health concerns for children and pregnant women as it is linked to higher chances of stillbirths, low birth weight and preterm births, according to the report. Exposure to high levels of heat also leaves children more vulnerable to developing chronic diseases and contracting

Follow fire protocol at hospitals to a T: Union health secy to states

Union Health Secretary Apurva Chandra on Monday called for strict compliance with fire-safety protocols in a meeting with states and healthcare organisations, citing an increased possibility of fires in hospitals with high temperatures. With the entire northern region reeling under a prolonged heatwave, incidents of fire, including in forests, are increasingly being reported. Several of these fire incidents were reported to be caused by short circuits which happened due to sub-optimal electrical maintenance and/or overload of electricity lines with heavy use of air-conditioners and other equipment. "Given the potential risks associated with fire hazards in hospitals, it is imperative that strict protocols and measures be put in place to prevent, detect and respond to fires effectively. "Establishing a robust fire safety plan and conducting fire-evacuation and safety drills will not only ensure compliance with regulatory requirements but also safeguard lives and property," Chandra .
