Months of scorching temperatures sometimes over 50 degrees Celsius (122 Fahrenheit) in parts of India this year left hundreds dead or ill. Official government records put the number of heat-related deaths this year as 110, but public health experts say that number is more likely in the thousands. Poor data collection methods and reporting are stopping the country from getting a more accurate picture of how deadly the heat is. Experts are concerned that it's hindering efforts to better prepare for future heat waves.
Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim
Flash drought, characterized by unusually rapid drying, can have substantial impact on many socioeconomic sectors, particularly agriculture. However, potential changes to flash drought risk in a warming climate remain unknown. In this study, projected changes in flash drought frequency and cropland risk from flash drought are quantified using global climate model simulations. We find that flash drought occurrence is expected to increase globally among all scenarios, with the sharpest increases seen in scenarios with higher radiative forcing and greater fossil fuel usage. Flash drought risk over cropland is expected to increase globally, with the largest increases projected across North America (change in annual risk from 32% in 2015 to 49% in 2100) and Europe (32% to 53%) in the most extreme emissions scenario. Following low-end and medium scenarios compared to high-end scenarios indicates a notable reduction in annual flash drought risk over cropland. Flash droughts are projected to become more frequent unde
Soaring temperatures in subcontinent, which have caused widespread suffering, would be extraordinarily rare without global heating
New analysis says that particulate pollution is the greatest threat to human health in India.
A new Imperial analysis has found that biogas and biomethane, while more climate friendly, leak up to twice as much methane as previously thought. Although biogas and biomethane remain climate-friendlier than non-renewable alternatives, the researchers call for better monitoring and fixing of leaks to ensure biogas and biomethane continue to live up to their green credentials.
Since the beginning of March, India and Pakistan and large parts of South Asia experienced prolonged heat, that at the time of writing, May 2022, still hasn’t subsided.
According to a new study from the Aarhus University in Denmark, humans will continue to wipe out mammalian species for the next 50 years, so much so that Earth will need three to five million years to recover its evolutionary diversity.
A brutal heatwave that has enveloped parts of southern Asia since the end of April looks set to intensify, says the latest forecast from the Met Office. Nick Silkstone is a meteorologist with the Met Office’s Global Guidance Unit. He said: “Temperatures are expected to peak on Saturday, when maximum values could reach around 49-50°C in the hottest locations, such as Jacobabad, and the Sibi area of Pakistan.
April temperatures at unprecedented levels have led to critical water and electricity shortages
In the early 2000s, the idea of giving legal rights to nature was on the fringes of environmental legal theory and public consciousness. Today, New Zealand’s Whanganui River is a person under domestic law, and India’s Ganges River was recently granted human rights. In Ecuador, the Constitution enshrines nature’s “right to integral respect”.
Sand dunes have declined by 16% between 1970 and 2013, said PC Moharana, principal scientist in natural resource division, Central Arid Zone Research Institute (CAZRI), who has extensively studied the changing environmental conditions in the desert regions. He clarified that the area under the habitat has turned the barren land into a cropped area with stabilisation of sand dunes as old as 10,000 years old while it will create to have an adverse impact on the unhabituated area — flora and fauna.
