IMD issues heatwave advisory as temperatures rise across north India

With temperatures rising across several regions, the India Meteorological Department (IMD) released detailed heatwave guidelines and advisories, officials said on Saturday. These include avoiding prolonged exposure to direct sunlight, especially during peak afternoon hours, staying adequately hydrated, wearing light and breathable clothing, and avoiding strenuous outdoor activities during high-temperature periods. The IMD advised special care for vulnerable groups such as children, the elderly, and individuals with pre-existing health conditions. "The department emphasised that early awareness and preventive action are critical in reducing heat-related illnesses such as heat exhaustion and heat stroke," an official said. In its latest assessment, the IMD said that maximum temperatures in many parts of northwest, central, and peninsular India currently range between 40 degrees Celsius and 44 degrees Celsius, with the highest temperature of 44.5 degrees Celsius recorded at Sri ...

Extreme heat: Kerala Disaster Management Authority issues public advisory

In view of rising temperatures across Kerala, the KSDMA has issued a comprehensive set of precautionary guidelines for the public to prevent heat-related illnesses. The Kerala State Disaster Management Authority (KSDMA), in a post on its social media handle, warned that extreme heat could lead to serious health conditions such as sunstroke, heat exhaustion, and dehydration, urging people to take adequate safety measures. According to the advisory, the public should avoid prolonged exposure to direct sunlight between 11 am and 3 pm. People have been advised to stay hydrated by drinking sufficient quantities of clean water even if they do not feel thirsty, while avoiding beverages like alcohol, coffee, tea, and carbonated drinks that may cause dehydration during the daytime. Wearing loose, light-coloured cotton clothing and using protective gear such as umbrellas, hats, and footwear while stepping outdoors have also been recommended. The KSDMA further suggested increasing the intake

Warming world increases number of days with fire-prone weather: Study

The number of days when the weather gets hot, dry and windy - ideal to spark extreme wildfires - has nearly tripled in the past 45 years across the globe, with the trend increasing even higher in the Americas, a new study shows. And more than half of that increase is caused by human-caused climate change, researchers calculated. What this means is that as the world warms, more places across the globe are prone to go up in flames at the same time because of increasingly synchronous fire weather, which is when multiple places have the right conditions to go up in smoke. Countries may not have enough resources to put out all the fires popping up and help won't be as likely to come from neighbours busy with their own flames, according to the authors of a study in Wednesday's Science Advances. In 1979 and for the next 15 years, the world averaged 22 synchronous fire weather days a year for flames that stayed within large global regions, the study found. In 2023 and 2024, it was up to mor

Wildfires and natural disasters cost world over $120 bn in 2025: Report

Heatwaves, wildfires, droughts, and storms cost the world more than USD 120 billion in 2025, according to a new report analysing the escalating cost of climate change. The report by UK-based NGO Christian Aid underscores the cost with fossil fuel companies playing a central role in driving the crisis. The report noted that cost of climate inaction is equally clear, as communities continue to bear the brunt of a crisis that could have been averted with urgent action to reduce greenhouse gas emissions. "These disasters are not natural they are the predictable result of continued fossil fuel expansion and political delay," said Emeritus Professor Joanna Haigh, at Imperial College London. The ten most financially costly events all had an impact of more than USD billion with the combined total topping more than USD 122 billion in damage. Most of these estimates are based only on insured losses, meaning the true financial costs are likely to be even higher, while the human costs are ofte

Delays in net zero will make heatwaves hotter, longer and more frequent

Heatwaves could be hotter, more prolonged and frequent, the longer countries delay in reaching net zero emissions, a balance between greenhouse gases emitted and those taken out from the atmosphere, according to a modelling study. Trends published in the journal 'Environmental Research: Climate' also indicate that heatwaves do not start to revert towards pre-industrial conditions for at least a millennium even after achieving net-zero targets. Regions in the Southern Hemisphere are projected to experience heatwaves of significantly increasing severity when net zero was modelled to occur by 2050 or later. Lead author Sarah Perkins-Kirkpatrick, professor of climate science at the Australian National University, said the work challenges a general belief that conditions after net zero will begin to improve for future generations. "While our results are alarming, they provide a vital glimpse of the future, allowing effective and permanent adaptation measures to be planned and implemente

Indians faced nearly 20 heatwave days in 2024 on average: Lancet report

People in India each experienced nearly 20 heatwave days in 2024 on average, of which about six-and-a-half days would not be expected were it not for climate change, according to a new global report published by The Lancet journal. Estimates suggest that an exposure to heat in 2024 resulted in a loss of 247 billion potential labour hours per year -- a record high of nearly 420 hours per person -- and 124 per cent more than that during 1990-1999. The agriculture sector accounted for 66 per cent, and construction sector for 20 per cent of the losses in 2024, according to the '2025 Report of The Lancet Countdown on Health and Climate Change'. A reduced capacity of labour due to the extreme heat is associated with a potential loss of income of USD 194 billion in 2024, it said. An international team of 128 experts from 71 academic institutions and UN agencies, led by University College London, were involved in producing the ninth edition of the report. Published ahead of the 30th UN ..

US heatwave smothers Pacific Northwest, poses risk in California, Arizona

Residents of the western US are sweltering in a heat wave that's already hospitalized some as temperatures will continue to hit dangerous levels throughout the weekend in Washington, Oregon, Southern California, Nevada and Arizona. Around 1.2 million people were under extreme heat risk Saturday, meaning temperatures are expected to stay dangerously high with no relief overnight. The largest area under the warning is around Tucson, Arizona, where the National Weather Service forecast dangerous highs between 102 and 107 degrees Fahrenheit (39 and 42 degrees Celsius). Areas of inland Southern California also faced extreme risk. Another 18.6 million are under major heat risk, affecting workers and anyone without regular cooling and hydration, including in Miami. Portland, Oregon, reported a record high for August 22, according to preliminary data. Struggling through the smothering heat were long-distance runners who were passing a baton in a relay race from inland Mt. Hood to the Pacifi
