Why are short-lived climate pollutants (SLCPs) so dangerous?

Wimbledon 2025 kicks off on June 30. Can Carlos Alcaraz make it three championship titles in a row? Or will Novak Djokovic manage to get his 25th Slam and equal Roger Federer’s record of eight Wimbledon titles? Can world no. 1 Jannik Sinner stamp his authority on grass for the first time this year? How do the various contenders stack up in what seems to be a very open field in the women’s draw? Is there a real frontrunner between the likes of world no. 1 Aryna Sabalenka, French Open champ Coco Gauff, and former Wimbledon champion Marketa Vondrousova? Can Ons Jabeur or Jasmine Paolini make a deep run this time around? Guest: Ziya Us Salam from The Hindu’s Delhi Bureau. Host: G.

When we think of climate and global warming, what comes to mind is carbon emissions, and how to decarbonise the economy. Lately, another front in the fight against climate change getting more and more attention: the battle against Short-Lived Climate Pollutants (SLCPs), also classified as non-carbon climate pollutants. These gases and chemicals — which include methane, black carbon, tropospheric ozone, hydrofluorocarbons -- have a much higher warming potential and shorter atmospheric lifetimes than CO2. So, what makes SLCPs deadly? What activities produce them? What can be done to mitigate their impact? And what is the nature of the challenge India faces with regard to SLCPs?

After 12 days of exchanging intense strikes and counter-strikes, Israel and Iran have reportedly agreed to a ceasefire. The ceasefire was first announced by President Donald Trump on social media. The war was initiated by Israel with the tacit approval of the US, to achieve certain objectives. Were those objectives achieved? What prompted them to initiate the ceasefire? Why did Iran agree to the ceasefire? With Israel’s attacks on Gaza continuing, will this ceasefire last?

With the blistering temperatures that most of India is suffering under, it should come as no surprise that May 2025 was the second-warmest month of May since records began. But what is of greater concern now, is how this heat is going to affect our future generations --  a new study has found that India recorded an average of six additional days of dangerously high temperatures for pregnant women every year over the last five years. What is this extreme heat doing the bodies of mothers to be? How does heat affect pregnancy outcomes? What will it mean for the near future, as India continues to experience heat waves?

According to the latest projections by the IMF, India is now the world’s fourth-largest economy. Government officials, including the CEO of NITI Aayog B.V.R. Subrahmanyam, have expressed confidence that India could soon overtake Germany to claim the third spot. Adding to the optimism, the World Bank recently reported that extreme poverty in the country fell to 5.3% in 2022–2023. A recent report by SBI noted that the poverty rate in India could now be in the range of 4%.  But what do these numbers mean for the broader population?

On June 13, Israel launched an all-out war against Iran. It carried out what has been described as a ‘decapitation strike” – taking out much of the country’s military leadership, as well as top nuclear scientists. It also attacked the country’s nuclear facilities and air defences, and subsequently it’s economic infrastructure and oil installations as well. Iran responded with missile strikes of its own, targeting Tel Avi and Haifa among other sites and military targets. While more than 200 people have been killed in Iran, more than 20 casualties have been reported in Israel. The two sides have been trading steadily escalating strikes since, and now Israel Prime Minister Benjamin Netanyahu is pressing hard for the US to join his war. How credible is Israel’s justification for starting the war – namely, that it wants to shut down Iran’s nuclear program – given that it is now speaking of regime change? How do the two sides stack up militarily if the conflict were to drag on? What are Iran’s options if the US joins the war?   Guest: Stanly Johny, The Hindu’s International Affairs Editor. Host: G.

India began its Crocodile Conservation programme in 1975, and this year marks 50 years of this initiative, one that has been more successful than most. India is home to three main kinds of crocodile species – the gharial, the salt water crocodile or salties, and the muggers. These species face increasing threats from habitat loss, poachers, pollution, riparian agriculture, artificial embankments, construction of barrages and dams, and illegal sand-mining. On the eve of World Crocodile Day, which falls on June 17, we look back at 50 years of crocodile conservation, the status of these endangered species as of today, and what is in store with the recent launch of the New Gharial Project by Prime Minister Narendra Modi. Guest: Professor B.C. Choudhury, eminent wildlife scientist who has worked on crocodile conservation since 1975. Host: G Sampath Edited by Jude Francis Weston Learn more about your ad choices.

The Central government recently proposed starting an integrated course – MBBS and Ayurveda medicine, at the Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER) in Puducherry. This proposed move has evoked a strong response from the Indian Medical Association who has said this unscientific mixing of various systems of medicine will benefit neither doctors, nor patients. This is not the first move to mix traditional and modern systems of medicine in India – other such measures for instance, have included proposals to allow traditional medical practitioners to prescribe modern medicine after a short course. What are the risks of mixing alternative systems of medicine with the MBBS course? Is there a benefit to integrated systems and if so, how should these be brought in? Has any other country managed to successfully combine alternative systems with modern, evidence based medicine?

Article 143 of the Constitution allows the President to seek the Supreme Court’s opinion on matters of law. This provision has been invoked by President Droupadi Murmu to raise 14 questions on a recent Supreme Court judgement. It concerns a case filed by the Tamil Nadu government against its Governor, who had withheld assent to 10 bills indefinitely. The Supreme Court has ruled in favour of the Tamil Nadu government, laying down a three-month timeline for Governors and the President to act on Bills passed by the State legislatures. The larger context of this development is the ongoing tussle between the Union government and Opposition-ruled States, with many wondering if this Presidential reference represents a political pushback from the Union government. Historically, what has been the logic for such references? How is this particular Presidential reference different in its substance from a review petition? Is the Supreme Court bound to take it up or can it decline the reference?

Yet again, we are talking about a virus we would much rather forget – Covid-19 is in the news with over 4,300 cases and over deaths as of June 4. New sub-variants, descendent from the Omicron lineage first reported at the end of 2021, are believed to be driving the spike in cases. So far however, a majority of the cases have been mild, with very few requiring hospitalisation, according to the government. Is Covid-19 here to stay? Do we have any reason to be concerned about the new variants? Do we need vaccines or booster shots again? And, what as individuals, can we do to stay safe? Guest: V.
