Nasa has declared 2023 as the year of open science. This leading space agency is making a long-term commitment to build an inclusive, open science community over the next decade. Open-source science is a commitment to the open-sharing of software, data, and knowledge (algorithms, papers, documents, ancillary information, etc) in a scientific process. The principles of open-source science are aimed at making publicly funded scientific research transparent, inclusive, accessible, and reproducible. To this end, Nasa recently took an open-science initiative called the Earth Information System (EIS) Freshwater. This is a groundbreaking initiative by Nasa because of its accessibility, reproducibility of actionable Earth information backed by its best satellite information, models, and tools. The EIS Freshwater studies are focused on quantification and changes in water stored in rivers, lakes, reservoirs, and creeks and streams. Among various components of the EIS (such as wildfire hydrology, risk of flooding, water security, AI application), we started exploring the flooding impact of climate change and human activities in populous global deltas. The delta component is that we can quantify the relative changes in hydrology and freshwater availability due to climate change and human intervention using an integrated modelling framework. In the most recent phase of the EIS initiative, we started exploring the concept's applicability in the Bengal delta.
India’s economy will become carbon neutral by the year 2070, the country’s prime minster has announced at the COP26 climate crisis summit in Glasgow. The target date is two decades beyond what scientists say is needed to avert catastrophic climate impacts. India is the last of the world’s major carbon polluters to announce a net-zero target, with China saying it would reach that goal in 2060, and the United States and the European Union aiming for 2050.
China's carbon emissions are vast and growing, dwarfing those of other countries. Experts agree that without big reductions in China's emissions, the world cannot win the fight against climate change. In 2020, China's President Xi Jinping said his country would aim for its emissions to reach their highest point before 2030 and for carbon neutrality before 2060. His statement has now been confirmed as China's official position ahead of the COP26 global climate summit in Glasgow. But China has not said exactly how these goals will be achieved.

A crucial U.N. conference heard calls on its first day for the world's major economies to keep their promises of financial help to address the climate crisis, while big polluters India and Brazil made new commitments to cut emissions. World leaders, environmental experts and activists all pleaded for decisive action to halt the global warming which threatens the future of the planet at the start of the two-week COP26 summit in the Scottish city of Glasgow on Monday. The task facing negotiators was made even more daunting by the failure of the Group of 20 major industrial nations to agree ambitious new commitments at the weekend.
