Over 7 lakh yearly deaths in India linked to abnormal temperatures: Lancet study

Source: The Hindu What is the news? An international team, led by researchers at Monash University in Australia, found that globally more than five million extra deaths a year can be attributed to non-optimal temperatures. The team looked at mortality and temperature data across the world from 2000 to 2019, a period when global temperatures… Continue reading Over 7 lakh yearly deaths in India linked to abnormal temperatures: Lancet study

NASA scientists fly over Greenland to track melting ice

NASA scientists will study how global warming is melting Greenland’s ice. Specifically, Scientists would study whether melting is being caused more by warm air or warm seawater. The project is known as Oceans Melting Greenland (OMG). To study the melting of ice, NASA scientists will fly over Greenland for 5 years in a Douglas DC-3… Continue reading NASA scientists fly over Greenland to track melting ice

July hottest month on record for the earth

The National Oceanic and Atmospheric Administration (NOAA) has announced that July was the hottest month on record (records date to 1880). The global average surface temperature in July 2019 was 0.95 degree Celsius warmer than the 20th century average. The previous hottest month on record was July 2016. The areas that had the most notable… Continue reading July hottest month on record for the earth

Earth is warming at faster pace than in last 2,000 years: study

According to studies published in the journals Nature and Nature Geoscience, world temperatures rose faster in the late 20th century than at any other time in the last 2,000 years. The paper published in Nature examined regional temperature trends over time. While, the paper published in Nature Geoscience examined rates of surface warming, averaged over… Continue reading Earth is warming at faster pace than in last 2,000 years: study

How global warming could impact jobs in India

The International Labour Organization (ILO) has released a report titled ‘Working on a Warmer Planet: The Impact of Heat Stress on Labour Productivity and Decent Work’. The report highlights how working hours will be lost because it is too hot to work or because workers work at a slower pace.  The projections are based on… Continue reading How global warming could impact jobs in India

Warming imperils clouds that deter ‘hothouse’ conditions

According to a recent research published in the journal Nature Geoscience, stratocumulus clouds could disappear if the amount of carbon dioxide into the atmosphere increases threefold. This could result in steep increase (by about 8 degree Celsius) in Earth’s temperature in addition to the global warming that comes from increased greenhouse concentrations. This would further lead to… Continue reading Warming imperils clouds that deter ‘hothouse’ conditions

Giant cavity in Antarctic glacier signals rapid decay

A NASA-led study has discovered a giant cavity growing at the bottom of the Thwaites Glacier. The glacier is located in western Antarctica and flows into Pine Island Bay, a part of the Amundsen Sea. According to NASA, the Thwaites Glacier is currently responsible for approximately 4% of global sea level rise. It holds enough… Continue reading Giant cavity in Antarctic glacier signals rapid decay

The ozone hole is recovering

The ozone hole is recovering News: A recent study by NASA has confirmed the recovery of the ozone layer due to the absence of chlorine from Chlorofluorocarbon(CFC) in the atmosphere. Important Facts: Findings of UN study: The study published in Geophysical Research Letters journal has confirmed the phenomenon by mapping the chemical composition of the… Continue reading The ozone hole is recovering

Oceans heating faster: study

Oceans heating faster: study News: According to a new study published in journal ‘Nature’, the scientists have noted that the global oceans may be absorbing up to 60 percent more heat since the 1990s than older estimates had found. Important Facts: New novel method in the study: Unlike earlier studies, which relied on tallying the… Continue reading Oceans heating faster: study
