New Delhi:

India experienced its second-hottest quarter from June to August this year since 1970, with over one-third of the country’s population enduring at least seven days of dangerous heat, according to a new report by a US-based group of climate scientists and communicators.

The report from Climate Central said climate change made high temperatures over three times more likely on 29 days during these three months.

“June through August 2024 was India’s second-hottest season since at least 1970, when reliable satellite records are available,” the report said, adding that India had the highest number of people exposed to climate change-driven temperatures in Southern Asia during this period.

More than 20.5 million people endured high temperatures heavily influenced by climate change for at least 60 days, it said.

More than 426 million people (about one-third of India’s population) faced at least seven days of dangerous heat, with temperatures exceeding 90 per cent of the usual highs for their areas from 1991 to 2020, the scientists said.

Globally, over 2 billion people (25 per cent of the global population) experienced 30 or more days of extreme heat, made at least three times more likely by climate change.

Several cities in India saw many days where temperatures were heavily influenced by climate change. Cities like Thiruvananthapuram, Vasai-Virar, Kavaratti, Thane, Mumbai, and Port Blair were the most affected, with each experiencing over 70 days of temperatures made at least three times more likely due to climate change.

Mumbai recorded 54 days of extreme heat caused by climate change. Meanwhile, Kanpur and Delhi experienced long periods of dangerously high temperatures, with average temperatures above 39 degrees Celsius, made four times more likely by climate change, the report added.

“High temperatures that were clearly influenced by climate change jeopardised the health of billions around the world during the past three months,” Andrew Pershing, vice president for science at Climate Central, said.

Vaibhav Pratap Singh, Executive Director, Climate and Sustainability Initiative (CSI), said the impacts of climate change are becoming increasingly evident for people and businesses across the country.

“Each year, we are experiencing more severe climate-related events such as floods, droughts, and heat waves, which are causing significant harm to lives and livelihoods.

“It is crucial to conduct assessments of how different levels of global warming are affecting our environment and combine this with an understanding of how it impacts people, jobs, and industries, including agriculture. This will help us identify the specific adaptation needs for different regions,” he said.

The world is witnessing weather extremes due to a combined effect of the 2023-24 El Nino and human-caused climate change.

With global temperatures for the January-August period recorded at 0.70 degrees Celsius above the 1991–2020 average, scientists have said it is increasingly likely that 2024 will be the warmest year on record.

India experienced 536 heatwave days this summer, the highest in 14 years, with the northwestern region recording its warmest June since 1901, according to the India Meteorological Department.

The country recorded 181 heatwave days in June, the highest since 2010.

Official data showed that India reported 41,789 suspected heatstroke cases and 143 heat-related deaths during one of its hottest and longest heatwaves.

The intense heat overwhelmed water supply systems and power grids, with Delhi grappling with a severe water crisis.

Temperatures breached 50 degrees Celsius in parts of Rajasthan, with nighttime temperatures hovering around 35 degrees Celsius in many areas.

In Delhi, which logged 40 consecutive days of temperatures above 40 degrees Celsius since May 13, around 60 heat-related deaths were reported this year, according to media reports.

New Delhi:

As the campaign heats up for the third phase of Lok Sabha elections, the weather department has predicted heatwave to severe heatwave conditions for several states over the next five days.

High temperatures have raised concern, as poll campaigns draw thousands of people under the baking sun.

Indian voters will be battling sweltering conditions to take part in the third phase of elections as heatwave conditions are likely to prevail in many states where voting will take place on May 7, especially West Bengal, Bihar, Karnataka, Kerala, Goa and East Uttar Pradesh.

The Election Commission has urged parties and authorities to do more to keep voters, candidates, and polling station staff safe. 

People should maintain extreme caution during such situations, the authorities have said. There are chances of people suffering sunburn and heatstroke, the weather office said.

Temperature in several areas of Maharashtra crossed 40 degrees Celsius yesterday, with Solaur the hottest at 43.7 degrees Celsius.

Scorching heatwave gripping Odisha and West Bengal has disrupted daily life, with temperatures soaring to alarming levels

The IMD also issued heat wave alert in Kerala’s Kollam, Thrissur, and Palakkad. The heat wave conditions would prevail in many places in these districts today, the IMD said.

Experts fear that the rising temperatures may impact the turnout in the third phase of polls.

According to the guidelines issued by the National Disaster Management Authority, people should wear light-coloured, loose-fitting clothes and cover the head with a cap or cloth. They should keep themselves covered and not expose too much of the body to the heat.

“Always carry plenty of fluids and water, and keep an eye on the daily forecast as well as advisories of the India Meteorological Department,” said Dr Naresh Kumar, Senior Scientist at the India Meteorological Department.

The threshold for a heat wave is met when the maximum temperature of a weather station reaches at least 40 degrees Celsius in the plains, 37 degrees in the coastal areas, and 30 degrees in the hilly regions, and the departure from normal is at least 4.5 notches.
