Climate change to make India hotter and wetter, drive 43% rise in extreme rains
A study by IPE Global and Esri India reveals that climate change is set to trigger a dramatic escalation in extreme rainfall events across India, compounding the country's already severe weather challenges.As global temperatures rise, Indian cities and rural districts are bracing for a future where heavy, erratic rains and heatwaves will become the new normal, with profound implications for lives, livelihoods, and infrastructure.advertisementAccording to the study, the intensity, frequency, and unpredictability of extreme heat and rainfall events have surged alarmingly over the past three decades. Between 1993 and 2024, India experienced a 15-fold increase in extreme heatwave days during the March–May and June–September periods.
Even more concerning is the fact that the last decade alone saw a 19-fold spike in such events. The study projects that by 2030, major urban centres — including Mumbai, Chennai, Delhi, Surat, Thane, Hyderabad, Patna, and Bhubaneswar—will witness a two-fold increase in heatwave days. However, it is the anticipated rise in extreme rainfall that is especially troubling: eight out of ten Indian districts are expected to experience multiple instances of erratic and intense rains by 2030.The research highlights a clear trend: as heatwave hotspots expand, so too does the likelihood of incessant and unpredictable rainfall. Coastal districts, both on the eastern and western coasts, are already experiencing more frequent and erratic downpours, a pattern set to intensify in the coming years.advertisementThe study estimates that the frequency of extreme rainfall events could rise by as much as 43% over current levels, driven by microclimatic changes and local drivers such as land-use change, deforestation, and encroachment on mangroves and wetlands.Abinash Mohanty, Head of the Climate Change and Sustainability Practice at IPE Global and lead author of the study, emphasized the urgency of action: 'The study and its stark findings suggest how climate change has exposed India to extreme heat and rainfall, and the situation is going to be grimmer and harsher by 2030, with the majority of urban centers impacted the most.'

He further warned that meteorological phenomena like El Nino and La Nina are gaining stronger momentum, resulting in abrupt surges in climate extremes such as floods, cyclones, storm surges, and extreme heat.The study calls for a paradigm shift in India's approach to climate resilience. It recommends hyper-granular risk assessments, the establishment of Climate Risk Observatories, and the appointment of heat-risk champions within district disaster management committees. These measures, it argues, are essential to safeguard agriculture, industry, and infrastructure from the mounting threats posed by climate change.According to Ashwajit Singh, Founder and Managing Director of IPE Global, 'Only then can India truly emerge as the climate solutions capital to the world'.Must Watch

Monsoon hits Delhi, covers entire nation 9 days early
Live Events (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel The monsoon covered the entire country on Sunday, nine days before the usual date of July 8 and reached Delhi two days ahead, the India Meteorological Department IMD ) to IMD data, this is the earliest the monsoon has covered the entire country since 2020, when it did so by June 26. "The monsoon has further advanced into remaining parts of Rajasthan, west Uttar Pradesh and Haryana and entire Delhi today," the IMD said in a said that heavy to very heavy rain is likely to continue in many parts of northwest, central, east and northeast India over the next seven southwest monsoon usually makes its onset over Kerala by June 1 and covers the entire country by July 8. It starts retreating from northwest India around September 17 and withdraws completely by October year, the monsoon reached Kerala on May 24, its earliest onset over the Indian mainland since 2009, when it arrived on May 23. However, this was followed by a prolonged stagnation of around 18 days, from May 29 to June 16. The monsoon reached Delhi on June 28 last year, June 25 in 2023, June 30 in 2022, July 13 in 2021 and June 25 in 2020. The system covered the entire country by July 2 in 2024, 2023 and 2022; July 13 in 2021 and June 26 in May, the IMD had forecast that India is likely to receive 106 per cent of the long-period average rainfall of 87 cm during the June-September monsoon season. Rainfall between 96 and 104 per cent of this 50-year average is considered 'normal'.Above-normal rainfall is expected in most parts of the country, except Ladakh, adjoining areas of Himachal Pradesh, the northeast and some parts of Bihar, Jharkhand, West Bengal and monsoon is crucial for India's agriculture sector, which supports the livelihood of around 42% of the population and contributes 18.2% to the GDP. It also plays a key role in replenishing reservoirs essential for drinking water and power generation.

Monsoon havoc in Pakistan: Flash floods and heavy rain killed 45 in just days, children among victims
Motorists drive through a flooded road caused by heavy monsoon rains, in Lahore, Pakistan, Sunday. At least 45 people have been killed across Pakistan as heavy rain and flash floods battered multiple regions since the start of the monsoon season, disaster management officials said on Sunday. The death toll includes a large number of children, underscoring the human cost of intensifying climate-related disasters in the country. The worst-hit was the Khyber Pakhtunkhwa province, bordering Afghanistan, where 21 people, including 10 children, lost their lives. The Swat Valley alone accounted for 14 deaths, where local media reported that a flash flood swept away families gathered near a riverbank. In Punjab, Pakistan's most populous province located along the Indian border, 13 people have died since Wednesday. Officials said eight of them were children, killed when walls or roofs collapsed during intense rainfall. The remaining victims were caught in sudden floods. Another 11 fatalities have been reported in Sindh and Balochistan, further highlighting the widespread impact of the seasonal downpour. The Pakistan Meteorological Department has warned that heavy rainfall and the risk of flash floods will persist until at least Saturday, urging residents in vulnerable areas to take precautions. This latest tragedy follows a string of extreme weather events in Pakistan. Just last month, 32 people were killed in violent storms, and earlier in the year, the country faced hailstorms and unusual temperature shifts during spring. With a population of over 240 million, Pakistan ranks among the world's most climate-vulnerable nations. Scientists and disaster experts have repeatedly warned that climate change is accelerating the frequency and severity of extreme weather, putting millions at risk in the region. Rescue and relief efforts are ongoing, and authorities have appealed for public vigilance as the monsoon deepens.

Earthquake Of 5.3-Magnitude Jolts Central Pakistan
A magnitude-5.3 earthquake struck central Pakistan on Sunday morning, according to the United States Geological Survey. There were no immediate reports of casualties or damage from the shallow quake, which USGS reported had occurred around 3:30 am (2230 GMT) with the epicentre around 60 kilometres (37 miles) north-northeast of Barkhan, a city in Pakistan's mountainous Balochistan province. Pakistan straddles the boundary where the Indian and Eurasian tectonic plates meet, making the country susceptible to earthquakes. The region can be challenging to navigate during crisis situations — in 2015, a 7.5-magnitude quake in Pakistan and Afghanistan killed almost 400 people across rugged terrain that impeded relief efforts. The country was also hit by a 7.6-magnitude quake in 2005 that killed more than 73,000 people and left about 3.5 million homeless, mainly in Pakistan-controlled Kashmir. Balochistan province, Pakistan's largest, saw a quake in 2021 that killed at least 20 people and left more than 10 injured, with landslides hampering initial rescue efforts in the remote mountainous district of Harnai.
