Experts to draft white paper on methane management for policy measures

A white paper on capturing methane, particularly coal bed methane, would soon be drafted and submitted to the government for it to take policy measures as potential of methane to warm environment is 84 times more than that of carbon dioxide. The white paper would also incorporate findings of the experts that investing in methane capture mining companies can increase revenues by 30 per cent. Methane is the second leading cause of climate change after carbon dioxide. The white paper shall be drafted on the basis of deliberation during day-long workshop Sustainable Mining & Methane Management' jointly organised last week by International Centre for Climate and Sustainability Action Foundation (ICSSA), Society for Clean Environment (SOCLEEN) and the Maharashtra government. It will be submitted to Ministry of Environment, Forests and Climate Change, Maharashtra, and State Environment Impact Assessment Authority (SEIAA). During the workshop, climate scientists suggested to state ...

Climate change to push 30% species over tipping points: Research

Climate change is likely to abruptly push up to 30 per cent species over tipping points as their geographic ranges reach unforeseen temperatures, according to a study. The researchers found that if the planet warms by 1.5 degrees Celsius, 15 per cent of species they studied will be at risk of experiencing unfamiliarly hot temperatures across at least 30 per cent of their existing geographic range in a single decade. However, this doubles to 30 per cent of species at 2.5 degrees Celsius of warming, they said. The study, published in the journal Nature Ecology & Evolution, analysed data from over 35,000 species of animals -- including mammals, amphibians, reptiles, birds, corals, fish, cephalopods and plankton -- and seagrasses from every continent and ocean basin, alongside climate projections running up to 2100. The researchers investigated when areas within each species' geographical range will cross a threshold of thermal exposure, defined as the first five consecutive years ...

UN forecasts 2 in 3 chance of briefly hitting key heat limit soon

There's a two-out-of-three chance within the next five years that the world will temporarily reach the internationally accepted global temperature threshold for limiting the worst effects of climate change, a new World Meteorological Organisation report forecasts. It likely would only be a fleeting and less worrisome flirtation with the agreed-upon climate danger point, the United Nations weather agency said on Wednesday. That's because scientists expect a temporary burst of heat from an El Nino will supercharge human-caused warming from the burning of coal, oil and gas to new heights and then slip back down a bit. The 2015 Paris climate agreement set 1.5 degrees Celsius (2.7 degrees Fahrenheit) as a global guardrail in atmospheric warming, with countries pledging to try to prevent that much long-term warming if possible. Scientists in a special 2018 United Nations report said going past that point would be drastically and dangerously different with more death, destruction and damag

Rich countries not doing enough to control climate change: Pacific island

Pacific Island leaders are criticising rich countries for not doing enough to control climate change despite being responsible for much of the problem, and for profiting from loans provided to vulnerable nations to mitigate the effects. Leaders and representatives from Pacific Island nations demanded at a UN climate change conference on Monday in Bangkok that the world make more effort to put aside differences in combating the environmental impact, especially as their countries emerge from the economic devastation of the COVID-19 pandemic. Prime Minister Mark Brown of the Cook Islands said the finance model for combatting climate change giving out loans to reduce the impact is not the way to go for countries in his region with such small populations that produce inconsequential amounts of carbon emissions but suffer the most from the effects. He encouraged a shift toward grants or interest-free loans to help ease the financial burden on poorer countries. All we're doing is adding

Study provides more evidence of climate change being human-caused: PNAS

A new research has provided evidence of climate change being human-caused and showed that specific signals from human activities have altered the temperature structure of Earth's atmosphere. Scientists have long recognised differences between tropospheric and lower stratospheric temperature trends as a "fingerprint" of human effects on climate. This fingerprint, however, neglected information from the mid to upper stratosphere, 25 to 50 kilometres above the Earth's surface, the inclusion of which improves the detectability of a human fingerprint by a factor of five, the scientists involved in the study said. "Enhanced detectability occurs because the mid to upper stratosphere has a large cooling signal from human-caused CO2 increases, small noise levels of natural internal variability, and differing signal and noise patterns," the study published in Proceedings of the National Academy of Sciences (PNAS) said. Noise in the troposphere can include day-to-day weather, interannual ...

Grounding line of Greenland's glacier shifts during ocean's tidal cycles

Glaciologists have found the grounding line of Petermann Glacier in northwest Greenland to shift substantially during tidal cycles, allowing warm seawater to intrude and melt ice at an accelerated rate. Grounding line of a glacier is where the ice detaches from the land bed and begins floating in the ocean. The researchers from the University of California, Irvine (UCI) and NASA's Jet Propulsion Laboratory (JPL), US, said that the findings from satellite radar data from three European missions suggested that the climate community could have been vastly underestimating the magnitude of future sea level rise caused by polar ice deterioration. Their research is published in the journal Proceedings of the National Academy of Sciences (PNAS). "Petermann's grounding line could be more accurately described as a grounding zone, because it migrates between 2 and 6 kilometers as tides come in and out," said lead author Enrico Ciraci, UCI assistant specialist in Earth system science and NASA

82% of Indians either alarmed or concerned about global warming, says study

About 82 per cent of Indians are either alarmed or concerned about global warming and are in support of bringing in energy policies to reduce its effects, reveals a new study. The study report, Global Warming's Four Indias, 2022: An Audience Segmentation Analysis, prepared by the Yale Program on Climate Change Communication and CVoter International, identified four types of audiences within the Indian public who were classified as 'The Alarmed', consisting of 54 per cent, 'The Concerned', 20 per cent, 'The Cautious', 11 per cent, and 'The Disengaged', consisting of just 7 per cent. The study has found that the majority of the people belonging to three segments backed the formulation of policies to fight climate change and opined that the Indian government should be doing more to address global warming. They also backed the development of a national programme to teach Indians about global warming, train people on renewable energy jobs, encourage local communities to build check dams

Study highlights regions most susceptible to harm due to heatwaves

A new study has highlighted under-prepared regions across the world most at risk of the devastating effects of scorching temperatures. The research, led by University of Bristol, UK, showed that unprecedented heat extremes combined with socioeconomic vulnerability puts certain regions, such as Afghanistan, Papua New Guinea, and Central America, most in peril. It is published in the journal Nature Communications. In this study, the researchers used extreme value statistics - a method to estimate the return periods of rare events - and large datasets from climate models and observations to pinpoint regions globally where temperature records are most likely to be broken soonest and the communities consequently in greatest danger of experiencing extreme heat. The researchers also cautioned that statistically implausible extremes, when current records are broken by margins that seemed impossible until they occurred, could happen anywhere. These unlikely events were found to have transpi

PM Modi calls for mass movement in global fight against climate change

Prime Minister Narendra Modi has said that an idea becomes a mass movement when it moves from "discussion tables to dinner tables" as he called for people's participation and collective efforts in combating climate change. He also told a gathering of world leaders via video link on Friday that when people become conscious that simple acts in their daily lives are powerful, there will be a very positive impact on the environment. "People across the world hear a lot about climate change. Many of them feel a lot of anxiety because they do not know what they can do about it. They are constantly made to feel that only governments or global institutions have a role. If they learn that they can also contribute, their anxiety will turn into action," Modi said while addressing the World Bank-organised "Making it Personal: How behavioral change can tackle climate change" conference. Modi hailed the World Bank for organising the event on impact of behavioural change on climate change, saying .
