Haldi, Pareecheek, Bhatt and Singh are among the top scientists who have written to Prime Minister Narendra Modi to warn of the dangers of the climate catastrophe and the need to take action on climate change.
Haldi, a leading scientist in the field of climate science, is a co-author of the Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) that is due to be released on November 28.
Pareepheek is a professor at the Tata Institute of Fundamental Research (TIFR) in New Delhi and an expert on climate and biogeochemistry.
He is also a director at TIFR.
Bhatt is a former director of the World Meteorological Organization, the UN’s climate-change body.
He has also written several papers on climate issues.
Pachavis is the co-director of the Institute of Environmental Studies (IES), a think tank that has studied climate and biodiversity issues for more than two decades.
He was instrumental in the formation of the Climate Action Task Force (CAPF) to formulate the strategy for tackling climate change in India.
Pachauri, a Nobel Prize-winning Indian physicist, is the country’s chief climate scientist and has also led a team that studied India’s emissions of CO2, and its role in causing the climate change phenomenon.
He died in 2017, aged 95.
The five scientists have also written to Modi in the past to highlight the need for a concerted international response to the climate crisis.
They have written in the letter to Modi that a failure to take a decisive action on global warming will lead to catastrophic consequences, including catastrophic global warming.
They also said that a lack of effective action by the international community will result in a “global catastrophe”.
They have also said a failure by India to act will create “a major crisis in the world”.
India, the world’s third-largest economy, has a climate policy under which the government is expected to slash its greenhouse gas emissions to below 30 per cent below 1990 levels by 2022.
The plan has been criticised for its reliance on cheap fossil fuels, and by some environmental activists as being too expensive.
