Even moderate temperature rise may cause increased hospital visits: Study

Even moderate temperature increases, for example night-time temperatures starting at 18.4 degrees Celsius, can lead to increased hospital visits and death in older adults and those with cardiorespiratory conditions, according to a study conducted in Canada. Researchers from the University of Waterloo and Toronto Metropolitan University in Canada have refined and expanded a method of data collection to assess the health impacts of heat waves and poor air quality. The new method, described in the journal Environmental Research, will help municipalities make a strong case for choosing which mitigation and adaptation measures to pursue to effectively respond to climate changes. The options could include planting more trees for shade, investing in emergency warning programmes, or planning to have more staff available to run ambulances, support hospitals and long-term care homes. "Much of the financial burden to mitigate the impacts of hot temperatures is left to municipalities, but the

Ground beneath us is heating up, civil infra not designed for it: Study

The ground beneath us is heating up, giving rise to the phenomenon of "underground climate change" and our civil infrastructure was not designed for it, scientists say. The continuous heat diffusion from buildings and underground transportation, seen in many urban areas around the world, causes the ground to warm at an alarming rate, found to be 0.1 to 2.5 degrees Celsius per decade by researchers. The heating up of ground leads to its deformation that includes both expansion and contraction, causing building foundations and the surrounding ground to move excessively and sometimes develop cracks, thereby impacting structures' long-term performance and durability. "The ground is deforming as a result of temperature variations, and no existing civil structure or infrastructure is designed to withstand these variations," said Northwestern University's Alessandro Rotta Loria, an assistant professor of civil and environmental engineering, and who led the US-based study published in the .

Third hottest day as Wednesday's temperature matches record set Tuesday

Earth's average temperature remained at a record high Wednesday, after two days in which the planet reached unofficial records. It's the latest marker in a series of climate-change-driven extremes. The average global temperature was 17.18 Celsius (62.9 degrees Fahrenheit), according to the University of Maine's Climate Reanalyzer, a tool that uses satellite data and computer simulations to measure the world's condition. That matched a record set Tuesday of 17.18 Celsius (62.9 Fahrenheit), and came after a previous record of 17.01 Celsius (62.6 degrees Fahrenheit) was set Monday. Scientists have warned for months that 2023 could see record heat as human-caused climate change, driven largely by the burning of fossil fuels like coal, natural gas and oil, warmed the atmosphere. They also noted that La Nina, the natural cooling of the ocean that had acted as a counter to that warming, was giving way to El Nino, the reverse phenomenon marked by warming oceans. The North Atlantic has seen .

Tuesday broke Monday's global record for hottest day ever: Report

The entire planet sweltered for the two unofficial hottest days in human recordkeeping Monday and Tuesday, according to University of Maine scientists at the Climate Reanalyzer project. For two straight days, the global average temperature spiked into uncharted territory. After scientists talked about Monday's dramatic heat, Tuesday soared 0.17 degrees Celsius (0.31 degrees Fahrenheit) even hotter, which is a huge temperature jump in terms of global averages and records. The same University of Maine climate calculator based on satellite data and computer simulations forecasts a similar temperature for Wednesday that would be in record territory, with an Antarctica average that is a whopping 4.5 degrees Celsius (8.1 degrees Fahrenheit) warmer than the 1979-2000 average. High temperature records were surpassed July 3 and 4 in Quebec and northwestern Canada and Peru. Cities across the US from Medford, Oregon to Tampa, Florida have been hovering at all-time highs, said Zack Taylor, a

Navi Mumbai where 12 people died due to sunstroke has no IMD observatory

Navi Mumbai, the city where 12 people died due to sunstroke after attending an award function, has no observatory of the India Meteorological Department (IMD) on the basis of which local weather alerts can be issued. On the Maharashtra government's request, the IMD had forecast that the temperature in Kharghar area of Navi Mumbai, where the function was held on Sunday, could reach 34-35 degrees Celsius, based on the data from its Santacruz observatory in neighbouring Mumbai, located 35 km away, MeT officials said. However, on ground the temperature rose to 38 degrees Celsius. The temperature was recorded by the nearest observatory in Maharashtra Industrial Development Corporation (MIDC) in Rabale area of Navi Mumbai. The observatory is operated by the Thane-Belapur Industrial Association. IMD scientist Sushma Nair told PTI that the observatory was revived in 2017 due to which enough observations are not there to calculate normals. "If we do not have any observatory near a venue wh

Planting trees could cut deaths from higher temperatures by third: Study

Planting more trees could decrease deaths from higher summer temperatures in cities by a third, according to a modelling study published in The Lancet journal. The study of 93 European cities found that increasing tree cover up to 30 per cent can help lower the temperature of urban environments by an average of 0.4 degrees Celsius and prevent heat-related deaths. Of the 6,700 premature deaths attributed to higher temperatures in cities during 2015, one third of these (2,644) could have been prevented by increasing urban tree cover up to 30 per cent, the researchers said. These findings highlight the need for more sustainable and climate-resilient strategies to be integrated into local policy decisions to aid climate change adaptation and improve population health, they said. "We already know that high temperatures in urban environments are associated with negative health outcomes, such as cardiorespiratory failure, hospital admission, and premature death," said study lead author, .
