Counter affidavit on behalf of Chief Municipal Engineer, Patna Nagar Nigam in the matter of Saurav Narayan Vs Bihar Pollution Control Board & Others dated May 20, 2025. The report said that the corporation has been diligently performing its statutory duties within the limitations of the available resources and infrastructure. …
The Earth could not be changed to save the environment, according to a new paper exploring the possibilities of "geoengineering" the planet to protect us from the worst effects of climate change. Injecting aerosols into the atmosphere is one of the great hopes for mitigating the effects of climate change. …
Carbon dioxide removal (CDR) approaches are efforts to reduce the atmospheric CO2 concentration. Here we use a marine carbon cycle model to investigate the effects of one CDR technique: the open ocean dissolution of the iron-containing mineral olivine. We analyse the maximum CDR potential of an annual dissolution of 3 …
Albedo modification (AM) is sometimes characterized as a potential means of avoiding climate threshold responses, including large-scale ice sheet mass loss. Previous work has investigated the effects of AM on total sea-level rise over the present century, as well as AM's ability to reduce long-term (Gt103 yr) contributions to sea-level …
Geo-engineering schemes like reflecting solar radiation or sucking CO2 out of the sky will not be a feasible way to reduce emissions for the next several decades, a new EU-funded report has warned. The analysis comes from the European Trans-disciplinary Assessment of Climate Engineering (EuTRACE), a multinational project set up …
Carbon dioxide removal (CDR) is the only geoengineering technique that allows negative emissions and the reduction of anthropogenic carbon in the atmosphere. Since the time scales of the global carbon cycle are largely driven by the exchanges with the natural oceanic stocks, the implementation of CDR actions is anticipated to …
When a chartered fishing boat strewed 100 tonnes of iron sulphate into the ocean off western Canada last July, the goal was to supercharge the marine ecosystem. The iron was meant to fertilize plankton, boost salmon populations and sequester carbon. Whether the ocean responded as hoped is not clear, but …
The deliberate injection of particles into the stratosphere has been suggested as a possible geoengineering scheme to mitigate the global warming aspect of climate change. Injected particles scatter solar radiation back to space and thus reduce the radiative balance of Earth. Previous studies investigating this scheme have focused primarily on …
The Conference of the Parties (COP) of the Convention on Biological Diversity (CBD) first turned its attention to geoengineering at its ninth meeting in 2008, in the context of ocean fertilization. The COP then requested Parties to ensure that ocean fertilization activities do not take place until there is an …
At the United Nations Framework Convention on Climate Change Conference in Cancun, in November 2010, the Heads of State reached an agreement on the aim of limiting the global temperature rise to 2 °C relative to preindustrial levels. They recognized that long-term future warming is primarily constrained by cumulative anthropogenic …
As the latest round of United Nations climate negotiations began in Durban, South Africa, expectations could scarcely have been lower. A globally binding deal is further away than ever. That makes considerable warming from climate change inevitable.
CALL it the fear of technology not proven yet or being plain cautious, but delegates from 193 countries voted to ban geoengineering. The technology aims to change the planet’s climate through manipulation. One example is to install mirrors in space to reflect solar radiation away from earth to reduce global …
After nearly two decades of negotiations between developing and developed countries, governments from across the world, including India, agreed to a UN treaty to manage and share the planet’s genetic resources and related traditional knowledge. The decision came on October 30, the last day of the two-week conference of parties …
As co-chair of Working Group III of the Intergovernmental Panel on Climate Change (IPCC), I would like to clarify your misleading implication that I recommend geoengineering as an option for attaining ambitious climate targets (Nature 468, 13
