Global South cities have only 70% of cooling capacity as North ones: Study

Cities in the Global South are equipped with only about 70 per cent of the "cooling capacity" provided by urban greenery in cities in the Global North and are, therefore, are more vulnerable to extreme heat, a new research has found. As the planet warms, researchers said that rising temperatures, along with 'urban heat island' effects, make cities hotter than rural areas. As a result, heat-related illness and deaths in these areas are becoming more common. An international team, including researchers from the University of Exeter, UK, analysed satellite data on 500 of the world's largest cities to assess 'cooling capacity' -- how much do the urban green spaces cool down a city's surface temperatures? "Our analysis suggests green spaces can cool the surface temperature in the average city by about 3 degrees Celsius during warm seasons -- a vital difference during extreme heat," author Timothy M. Lenton, from the University of Exeter, said. "However, a concerning disparity is evident

'Hellishly hot' southern Europe bakes under heat wave as temp tops 104F

The Italian health ministry placed 12 cities under the most severe heat warning Tuesday as a wave of hot air from Africa baked southern Europe and the Balkans and sent temperatures over 40 degrees Celsius (104 degrees Fahrenheit), with the worst still to come. Croatia reported the highest-ever temperatures of the Adriatic Sea, with the thermometer reaching nearly 30 degrees Celsius (86 degrees Fahrenheit) at the southern walled city of Dubrovnik, the country's most popular tourism spot. In Serbia, the state power company reported record consumption Tuesday due to the use of air conditioning. Municipal authorities in several southern European and Balkan cities took measures to look after elderly people in particular as civil protection crews fielded calls for water-dropping aircraft such as Canadairs to douse wildfires that raged in southern Italy and North Macedonia. It's hellishly hot," said Carmen Daz, a tourist from Madrid who was trying to keep cool with a fan at lunchtime in ..

Groundwater to heat over 3 degrees C by century end, risking safety: Report

Groundwater is projected to warm by 2-3.5 degrees Celsius before the turn of this century, potentially risking water quality and safety, apart from threatening ecosystems depending on the resource, a new research has found. The "world's first global groundwater temperature model" predicted the highest warming rates in Central Russia, Northern China and parts of North America, and the Amazon rainforest in South America. A team of researchers, led by those from the Karlsruhe Institute of Technology, Germany, said while a lot of focus on climate change concerns weather events and water availability, we also need to think about how it impacts groundwater, critical to life on the planet. Warming of groundwater can adversely impact ecosystems relying on them, they said. "Rivers rely on groundwater to keep flowing during dry times. Warm waters hold less dissolved oxygen," explained study co-author Gabriel Rau from the University of Newcastle, UK. The model also estimated that by 2100, 60

Global weather body predicts 60% chance of La Nia developing during Jul-Sep

The 2023/24 El Nio event, which drove record-breaking temperatures and extreme weather around the world, is predicted to transition to La Nia conditions later this year, according to a new update from the World Meteorological Organization (WMO). The world experienced the warmest April ever and the eleventh consecutive month of record-high temperatures. Sea surface temperatures have been record-high for the past 13 months, according to the WMO. The WMO said this is happening due to the naturally occurring El Nio unusual warming of waters in the central and eastern Pacific Ocean and the additional energy trapped in the atmosphere and ocean by greenhouse gases from human activities. Amid a prevailing but weakening El Nio, millions of people in South Asia, including India and Pakistan, endured brutal heat in April and May. The latest forecasts from the WMO Global Producing Centres of Long-Range Forecasts give equal chances (50 per cent) of either neutral conditions or a transition to
