Delhi Monsoon: दिल्ली में साल दर साल बढ़ती जाएगी, क्या तैयार हैं हम? इस साल प्री-मॉनसून सीजन में गर्मी ने तोड़ा 6 साल का रेकार्ड

Delhi Monsoon: दिल्ली में साल दर साल बढ़ती जाएगी, क्या तैयार हैं हम? इस साल प्री-मॉनसून सीजन में गर्मी ने तोड़ा 6 साल का रेकार्ड भले मॉनसून आ चुका है लेकिन गर्मी से राहत मिलना बाकी है। गर्मी साल दर साल बढ़ती जाएगी, लेकिन क्या हम इस बढ़ती गर्मी से निपटने के लिए तैयार हैं? यह सवाल सीएसई ने एक रिपोर्ट जारी करते हुए उठाए हैं। रिपोर्ट में सीएसई (सेंटर फॉर साइंस एंड एनवायरमेंट) ने दावा किया है कि 2022 में प्री मॉनसून सीजन 2016 के बाद सबसे गर्म रहा है। मार्च से मई तक प्री मॉनसून सीजन होता है। इस साल इन तीन महीनों में सामान्य से 1.24 डिग्री अधिक गर्मी रही। यह 2016 के प्री मॉनसून सीजन से 1.20 डिग्री अधिक है लेकिन 2010 के प्री मॉनसून सीजन से 1.45 डिग्री कम है। इस रिपोर्ट में दूसरा चौकाने वाला दावा यह किया गया है कि मॉनसून सीजन प्री मॉनसून सीजन से गर्म होता जा रहा है। जबकि सर्दियों और पोस्ट मॉनसून सीजन भी तेजी से गर्म हो रहा है। देश के स्तर पर मॉनसून सीजन में गर्मी प्री मॉनसून सीजन के अनुपात में 0.3-0.4 डिग्री तक अधिक हो रही है। वहीं मॉनसून की तुलना में पोस्ट मॉनसून सीजन में भी 0.73 डिग्री और सर्दियों में 0.68 डिग्री गर्मी बढ़ रही है।

आखिर क्यों बदल रहा मौसम का मिजाज? मॉनसून के पहले भीषण गर्मी का टूटा 6 साल पुराना रिकॉर्ड

हाल के वर्षों में तापमान बढ़ा है। सीएसई की स्टडी रिपोर्ट के मुताबिक दिल्ली में वायु तापमान 2010 की तुलना में 1.77 डिग्री सेल्सियस अधिक गर्म रहा है और भू-सतह तापमान 1.95 डिग्री सेल्सियस अधिक गर्म रहा है।

आखिर क्यों बदल रहा मौसम का मिजाज? मॉनसून के पहले भीषण गर्मी का टूटा 6 साल पुराना रिकॉर्ड

नई दिल्ली: इस साल गर्मी के मौसम (Temperature This Year) ने देश में मॉनसून पूर्व दूसरे सर्वाधिक गर्म मौसम के तौर पर 2016 का रिकार्ड तोड़ दिया। जबकि सर्दियों का मौसम या मॉनसून (Monsoon Season) बाद के मौसम में तेजी से तापमान बढ़ रहा है। सेंटर फॉर साइंस एंड इन्वायरोंमेंट (CSE) के अर्बन लैब के नए रिपोर्ट में यह कहा गया है। अध्ययन के मुताबिक, दिल्ली में भू-सतह का तापमान 2010 से सर्वाधिक रहा है और शहर में तापमान के सभी तीन मानदंडों पर उम्मीद से अधिक तापमान दर्ज किया गया। आखिर क्यों बढ़ रहा है तापमान गर्मी बढ़ने की प्रवृत्ति को समझने की कोशिश के तहत सीएसई ने सतह वायु तापमान, भू-सतह तापमान और सापेक्षिक आर्द्रता (उष्मा सूचकांक) की तापमान प्रवृत्तियों का विश्लेषण किया। अध्ययन में कहा गया है कि दिल्ली में वायु तापमान 2010 की तुलना में 1.77 डिग्री सेल्सियस अधिक गर्म रहा है और भू-सतह तापमान 1.95 डिग्री सेल्सियस अधिक गर्म रहा है। तापमान बढ़ने से लोग हुए असहज सीएसई की स्टडी में कहा गया है कि प्रतिदिन औसत उष्मा सूचकांक जून 2022 में 40 डिग्री सेल्सियस को पार कर गया। इसमें कहा गया है कि दिल्ली में मार्च और अप्रैल का महीना आमतौर पर सामान्य रहा लेकिन मई में छिटपुट स्थानों पर बारिश की बौछार पड़ने के साथ आर्द्रता बढ़नी शुरू हो गई। हालांकि, आर्द्रता में इस वृद्धि ने शहर में उष्मा सूचकांक को बढ़ा दिया जिससे संकेत मिलता है कि तापमान बढ़ने से लोगों ने असहजता महसूस की। मई 2022 में सर्वाधिक तापमान सीएसई के अध्ययन में कहा गया है, सर्वाधिक भू-सतह तापमान 16 मई 2020 को दर्ज किया गया जब शहर में यह 53.9 डिग्री सेल्सियस रहा। इसके बाद मई 2022 में सर्वाधिक भू-सतह तापमान 51.8 डिग्री सेल्सियस दर्ज किया गया। पिछले वर्षों में अधिकतम भू -सतह तापमान 45 डिग्री सेल्सियस के आसपास दर्ज किया गया था।

प्री-मानसून सीजन इस साल भारत में दूसरा सबसे गर्म मौसम; सर्दियां तेजी से गर्म हो रही हैं: अध्ययन

सेंटर फॉर साइंस एंड अर्बन लैब के नवीनतम निष्कर्षों के अनुसार, इस साल गर्मी या प्री-मानसून सीजन ने देश में दूसरे सबसे गर्म प्री-मॉनसून सीजन के रूप में 2016 के रिकॉर्ड को पीछे छोड़ दिया है, वहीं सर्दी और मानसून के बाद के मौसम तेजी से गर्म हो रहे हैं। पर्यावरण। अध्ययन के अनुसार, दिल्ली में भूमि की सतह का तापमान 2010 के बाद से सबसे अधिक रहा है और शहर ने तीनों तापमान मापदंडों पर एक महत्वपूर्ण सकारात्मक विसंगति (उम्मीद से अधिक तापमान) दर्ज की। वार्मिंग की प्रवृत्ति को व्यापक रूप से समझने के लिए, सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) के अध्ययन ने गर्मी के तनाव के सभी तीन आयामों – सतही हवा का तापमान, भूमि की सतह का तापमान और सापेक्ष आर्द्रता को कवर करके तापमान के रुझान का विश्लेषण किया है। (ताप सूचकांक)। अध्ययन में कहा गया है कि दिल्ली में, हवा का तापमान 2010 की तुलना में 1.77 डिग्री सेल्सियस अधिक गर्म रहा है, और भूमि की सतह का तापमान 1.95 डिग्री सेल्सियस अधिक गर्म है। सीएसई के विश्लेषण के अनुसार, जून, 2022 में दैनिक औसत ताप सूचकांक 40 डिग्री सेल्सियस को पार कर गया। इसने कहा कि दिल्ली में मार्च और अप्रैल असामान्य रूप से शुष्क रहे हैं, लेकिन मई में कुछ छिटपुट बारिश के साथ आर्द्रता बढ़ने लगी। लेकिन आर्द्रता में इस वृद्धि से शहर में गर्मी सूचकांक में वृद्धि हुई है, जो आबादी के बीच थर्मल असुविधा में वृद्धि का संकेत देता है। “भूमि की सतह का उच्चतम तापमान 16 मई, 2020 को देखा गया था, जब शहर की सीमा के भीतर 53.9 डिग्री सेल्सियस दर्ज किया गया था, इसके बाद 14 मई, 2022 को अधिकतम भूमि की सतह का तापमान 51.8 डिग्री सेल्सियस दर्ज किया गया था। पिछले वर्षों में, अधिकतम भूमि की सतह का तापमान देखा गया था। 40 के दशक के मध्य में होने के लिए,” सीएसई के निष्कर्षों में कहा गया है। इसने आगे कहा कि मई, 2022 में हीटवेव के दौरान, दिल्ली भर में भूमि की सतह का तापमान 38 डिग्री सेल्सियस से ऊपर चला गया, जो “असामान्य था क्योंकि शहर के भीतर हरे रंग की जेबें पिछले वर्षों में इस परिमाण तक गर्म नहीं हुई हैं,” और यह कि औसत भूमि की सतह का तापमान दैनिक औसत हवा के तापमान से अधिक हो रहा है। “औद्योगिक और कृषि क्षेत्र में मार्च से मई के बीच भूमि की सतह के तापमान में सबसे अधिक वृद्धि दर्ज की गई है। उत्तर, दक्षिण-पश्चिम और उत्तर-पश्चिम दिल्ली में शहर की परिधि के क्षेत्रों में 19 मार्च से 14 मई, 2022 तक अत्यधिक उच्च सतह के तापमान में वृद्धि देखी गई है।” अध्ययन ने कहा।

Pre-monsoon season this year second hottest in India; winters warming up faster: CSE study-Business Journal

While summer or pre-monsoon season this year has overtaken 2016 records as the second hottest pre-monsoon season in the country, winter and post-monsoon seasons are warming up faster, according to the latest findings by the Urban Lab of Centre for Science and Environment. According to the study, land surface temperatures in Delhi have been the highest since 2010 and that the city recorded significant positive anomaly (temperature higher than expected) on all three temperature parameters. In a bid to understand the warming trend in a comprehensive way, the study by Centre for Science and Environment (CSE) has analysed the temperature trends by covering all three dimensions of heat stress — surface air temperature, land surface temperature, and relative humidity (heat index). In Delhi, air temperature has been 1.77 degrees Celsius hotter than 2010, and the land surface temperature 1.95 degrees Celsius hotter, the study said. According to the CSE analysis, the daily average heat index crossed 40 degrees Celsius in June, 2022. It said March and April have been unusually dry in Delhi, but humidity started to rise in May with some scattered rain spells. But this spike in humidity has led to an increase in the heat index in the city, indicating increased thermal discomfort among the population. “The highest land surface temperature was observed on May 16, 2020 when 53.9 degrees Celsius was recorded within city limits, followed by May 14, 2022 with maximum land surface temperature of 51.8 degrees Celsius. In the previous years, maximum land surface temperature was observed to be in mid-40s range,” the CSE findings said. It further said during the heatwave in May, 2022, the land surface temperature across Delhi shot above 38 degrees Celsius, which was “unusual as the green pockets within the city have not heated up to this magnitude in the previous years,” and that the average land surface temperature has been getting higher than daily average air temperature. “Industrial and agricultural zone recorded highest increase in land surface temperature between March to May. The regions at the city periphery in the north, southwest, and northwest Delhi have seen the extremely high surface temperature rise from March 19 to May 14, 2022,” the study said. The study further noted that even the temperature of the water bodies rose to 29-30 degrees Celsius in May, which were well below 27 degrees Celsius in March. According to CSE’s analysis on air temperature variation among city’s stations, Chandni Chowk recorded the highest average air temperature on May 14, 2022 with 40.39 degrees Celsius, followed by Punjabi Bagh at 40.29 degrees Celsius, Mundka at 39.5 degrees Celsius and Paharganj at 39.1 degrees Celsius. CSE said the objective of the city analysis was to understand the combined effect of climate change induced unseasonal heatwaves. The study is based on comparative statistical analysis of temperature anomalies and observed heat-related impact in Indian cities and regions.

Why is the weather pattern changing? 6 year old record of severe heat broken before monsoon

This year’s summer season broke the record of 2016 as the second hottest pre-monsoon season in the country. Whereas the winter season or the later season of the monsoon season is rapidly increasing the temperature. This has been said in a new report by the Urban Lab of the Center for Science and Environment (CSE). According to the study, the ground-surface temperature in Delhi has been the highest since 2010 and the city recorded above-expected temperatures on all three temperature parameters. Why is the temperature rising In an attempt to understand the warming trend, CSE analyzed the temperature trends of surface air temperature, ground surface temperature and relative humidity (heat index). The study said that the air temperature in Delhi was 1.77 °C warmer than in 2010 and the ground surface temperature was 1.95 °C warmer than in 2010. Delhi-NCR Weather Today: Rain, giving relief from the sultry heat, one more day away from Delhiites, now there is a possibility of rain from Thursday to Saturday People were uncomfortable due to rising temperature The CSE study said that the average daily heat index crossed 40 degrees Celsius in June 2022. It said that the months of March and April were generally normal in Delhi but in May the humidity started increasing with isolated rain showers. However, this increase in humidity raised the heat index in the city, indicating that people felt uneasy due to the rise in temperature. Delhi Rain: Date on date… Why is the Meteorological Department trying to predict the rain of Delhi Highest temperature in May 2022 The CSE study said the highest ground surface temperature was recorded on 16 May 2020 when it was 53.9 degrees Celsius in the city. After this, the highest surface temperature of 51.8 degree Celsius was recorded in May 2022. The maximum ground surface temperature recorded in previous years was around 45 °C.

Pre-monsoon season this year second hottest in India; winters warming up faster: Study

With the summer or pre-monsoon season in 2022 overtaken 2016 records as the second hottest pre-monsoon season in the country, winter and post-monsoon seasons are warming up faster, reported Centre for Science and Environment (CSE) on 7 July. According to the study, since 2010, the land surface temperatures in Delhi have been the highest and that the city recorded significant positive anomaly on all three temperature parameters.

2022 Pre-monsoon Summer Heat Overtake 2016 As 2nd Hottest Pre-monsoon Season On Record: CSE

While extreme heat waves in the states of the northwest draw maximum public attention, the increase in overall anomalous temperature in other regions of the country have been largely neglected, indicated a new country-wide analysis by Centre for Science and Environment (CSE) on Thursday. The seasonal average air temperature for 2022 summer was 1.24 degrees Celsius warmer than the baseline trends.Moreover, the heat waves lashing India this summer are symptomatic of the anomalous temperature trends that is expected to worsen with growing climate change impacts, it said. Year 2022 summer was the second Hottest after the summer of 2010.Mega cities, including Delhi, Mumbai, Kolkata and Hyderabad are much hotter than the larger region around them due to heat island effects caused by surface absorption of heat and local waste heat generated by traffic, industry and air conditioning (among other urban activities), the latest CSE analysis said. Talking about the increase in overall anomalous temperature in other regions of the country that have been largely neglected, “This is a very disturbing trend as policy preparedness to mitigate rising heat due to climate change is nearly absent in India,” said Anumita Roychowdhury, executive director, research and advocacy, CSE. “Without heat action plans, rising air temperature, radiating heat from land surfaces, concretisation, heat-trapping built structures, waste heat from industrial processes and air conditioners, and erosion of heat dousing forests, urban greens and waterbodies will worsen public health risks.This requires urgent time-bound mitigation,” she said. Avikal Somvanshi, senior programme manager, Urban Lab, CSE, said: “Currently, the attention is largely on the maximum daily heat levels and extreme conditions of heat waves.But it is equally important to pay attention to the overall rising temperature and humidity trends in different regions to understand the gravity of the problem.” The Urban Lab of CSE has analysed the temperature trends in India from January 2015 till May 2022.The effort has been to understand the warming trends by covering all three dimensions of heat stress — surface air temperature, land surface temperature, and relative humidity (heat index) — at the national, regional and local levels. The seasonal average air temperature for 2022 — pre-monsoon or summer (March, April and May as per IMD classification) — is 1.24 degrees Celsius warmer than the baseline trends that relate to 1971-2000 climatology. Baselines are defined based on historical timelines and may vary for different metrics; the anomaly is generally computed from the 1951-80, 1971-2000, or 1981-2010 climatology baseline. This is warmer than the 1.20 degrees Celsius anomaly noted in 2016 pre-monsoon, but lower than the 1.45 degrees Celsius anomaly recorded in the 2010 pre-monsoon season. Similarly, land surface temperature anomaly has been extreme this pre-monsoon Season, with a 1.46 degrees Celsius departure from the baseline (1971-2000).It must be noted that pre-monsoon seasonal trends in both land and air temperature are identical to the annual trends, but with more pronounced highs and lows. monsoon is hotter than the pre-monsoon period on an average, while winter and post-monsoon seasons are warming up faster. High heat stress and heat waves in the northwestern states, but Other regions even hotter in absolute terms.

elhi hotter than earlier than with extra hotspots, higher variations in most temperatures | Delhi Information

Delhi has develop into hotter than earlier than with extra warmth hotspots, excessive variations in most temperatures inside metropolis areas and sudden rise of mercury as much as 26 levels Celsius in areas inside a month. These findings point out that the town could have to rethink its local weather motion plans to take care of the hovering warmth stress, stated consultants. Centre for Science and Atmosphere (CSE) has analysed the temperature traits for Delhi, together with Mumbai, Kolkata and Hyderabad, from January 2015 to Might 2022. jk The research revealed that whereas Delhi recorded a big rise in all three temperature parameters — floor air temperature, land floor temperature and relative humidity (warmth index), it additionally has most variations in temperatures in numerous areas. Loss in inexperienced cowl, seasonal lack of vegetation and concrete actions are believed to be among the many causes behind the drastic rise within the variety of warmth hotspots in Delhi. The research famous that after peaking of pre-monsoon temperatures in 2016 — one of many hottest summers within the metropolis, it had been cooling down till this 12 months. Delhi is way extra drier than different cities the place vegetation is extra constant and evergreen. Vegetation in Delhi additionally fluctuated as per season, attributable to climate and crop harvest. Apart from, growth work results in loss in tree cowl,” stated Avikal Somvanshi, senior programme supervisor at CSE and lead creator of the research. There’s a have to have a multi-sectoral effort, not restricted to planting timber and placing up symbolic photo voltaic panels. “The town must re-assess its plans to adapt to future warmth circumstances and give attention to creating resilience,” Somvanshi emphasised. The report acknowledged that air floor temperature was at the moment 1.77 levels Celsius greater than the 1981-2010 baseline, whereas the land floor temperature was 1.95 levels Celsius extra. The warmth index is up by 1.64 levels Celsius in contrast with the 2010-19 baseline. “Mega cities, together with Delhi, Mumbai, Kolkata and Hyderabad, are a lot hotter attributable to warmth island results brought on by floor absorption of warmth and native waste warmth generated by site visitors, trade and airconditioning, amongst different city actions,” the report identified. Concerning the extent to which land floor temperature soars briefly length in Delhi, it discovered that between March 19 and Might 14, 2022, the temperature in Narela soared by 26.5 levels Celsius, adopted by 25.3 in Bawana, 24 in Matiala, 23.9 in Mundka, 22.9 in Najafgarh, 22.8 in Burari, and 20.7 in Karawal Nagar. The research additionally identified absence of sure system like not contemplating humidity and warmth index, or the texture temperature. “March and April have been unusually dry in Delhi, however humidity began rising in Might, which introduced reduction from heatwaves. However the spike in humidity has led to a rise within the warmth index within the metropolis, indicating an elevated discomfort amongst individuals,” the report identified. However since India Meteorological Division “doesn’t account for humidity in its consideration for heatwaves, risks of humid warmth that’s identified to be extra deadly to people doesn’t get reported”, it added. Sir Fort and Chandni Chowk had been on common had been the most popular neighbourhoods. “With out pressing time-bound mitigation, rising air temperature, radiating warmth from land surfaces, heat-trapping constructed buildings, waste warmth from industrial processes and airconditioners, and erosion of forests, city greens and waterbodies will worsen public well being dangers,” stated Anumita Roychowdhury, govt director of CSE.

Heat stress rising in India, heat waves second biggest killer among natural forces

Even though the monsoon has begun to affect the entire country, many areas still seem to be experiencing intense heat which is exacerbated by sharp increases in humidity. This summer's heat waves in India are a reflection of the unusual temperature trends that are anticipated to get worse as the effects of climate change become more pronounced. After the summer of 2010, the summer of 2022 has been the second-hottest summer since 2016. Due to heat island effects brought on by surface heat absorption and local waste heat produced by traffic, industry, and air conditioning, megacities like Delhi, Mumbai, Kolkata, and Hyderabad are significantly hotter than the greater territory around them (among other urban activities). According to a recent country-wide by the Centre for Science and Environment (CSE), while extreme heat waves in the northwest states as defined by the India Meteorological Department (IMD) attract the most public attention, the rise in overall anomalous temperature in other parts of the nation has been largely ignored. "This is a very disturbing trend as policy preparedness to mitigate rising heat due to climate change is nearly absent in India. Without heat action plans, rising air temperature, radiating heat from land surfaces, concretisation, heat-trapping built structures, waste heat from industrial processes and air conditioners, and erosion of heat dousing forests, urban greens and water bodies will worsen public health risks. This requires urgent time-bound mitigation," said Anumita Roychowdhury, executive director, research and advocacy, CSE. Avikal Somvanshi, senior programme manager, Urban Lab, CSE said "Understanding the overall temperature anomaly, extreme heat conditions, and the mixed trends in heat patterns across different regions of India has become necessary to assess the emergent risk. Currently, the attention is largely on the maximum daily heat levels and extreme conditions of heat waves. But it is equally important to pay attention to the overall rising temperature and humidity trends in different regions to understand the gravity of the problem". Data from the National Crime Records Bureau (NCRB) that also captures accidental deaths including those from climatic stress, shows that between 2015 and 2020, 2,137 people had reportedly died due to heat stroke in the states in the northwest. But the southern peninsula region had reported 2,444 deaths due to excessive environmental heat, with Andhra Pradesh alone accounting for over half of the reported casualties. Delhi reported only one death for the same period. Most deaths have been reported among working-age men (30-60-year-olds), usually not considered highly vulnerable to temperature anomalies. The understanding of the public health impacts of meteorological conditions like heat waves is still weak in India. Heat waves are the second most deadly natural force in India, having killed over 20,615 people during 2000-20. Lightning, with 49,679 deaths, was the top killer. There has been a decline in the number of reported deaths since 2015 when IMD reported 2,081 deaths and NCRB reported 1,908 deaths. There were no deaths reported by IMD in 2021 and NCRB is yet to publish the 2021 edition of its annual Accidental DeathsSuicides in India (ADSI). The temperature trends in India from January 2015 to May 2022 were studied by the Urban Lab of CSE. Surface air temperature, land surface temperature, and relative humidity (heat index) have been studied at the national, regional, and local levels in an effort to understand the patterns in global warming. Additionally, the patterns in the metropolises of Delhi, Mumbai, Kolkata, and Hyderabad in each of the four homogeneous zones of the IMD have been evaluated. A CSE release said the temperature anomaly has been examined by the analysis (which refers to a departure from a reference value or long-term average or a baseline). A positive anomaly means that the temperature was higher than the baseline, whereas a negative anomaly means that it was lower. It typically serves to report monthly, seasonal, yearly, or decadal fluctuations in temperature. Although significantly shorter in duration and characterised in contrast to an absolute temperature threshold as well as deviation from the usual, heat waves are likewise anomalous temperature events.

Heat stress rising in India, heat waves second biggest killer among natural forces

Even though the monsoon has begun to affect the entire country, many areas still seem to be experiencing intense heat which is exacerbated by sharp increases in humidity. This summer's heat waves in India are a reflection of the unusual temperature trends that are anticipated to get worse as the effects of climate change become more pronounced. After the summer of 2010, the summer of 2022 has been the second-hottest summer since 2016. Due to heat island effects brought on by surface heat absorption and local waste heat produced by traffic, industry, and air conditioning, megacities like Delhi, Mumbai, Kolkata, and Hyderabad are significantly hotter than the greater territory around them (among other urban activities). According to a recent country-wide by the Centre for Science and Environment (CSE), while extreme heat waves in the northwest states as defined by the India Meteorological Department (IMD) attract the most public attention, the rise in overall anomalous temperature in other parts of the nation has been largely ignored. "This is a very disturbing trend as policy preparedness to mitigate rising heat due to climate change is nearly absent in India. Without heat action plans, rising air temperature, radiating heat from land surfaces, concretisation, heat-trapping built structures, waste heat from industrial processes and air conditioners, and erosion of heat dousing forests, urban greens and water bodies will worsen public health risks. This requires urgent time-bound mitigation," said Anumita Roychowdhury, executive director, research and advocacy, CSE. Avikal Somvanshi, senior programme manager, Urban Lab, CSE said "Understanding the overall temperature anomaly, extreme heat conditions, and the mixed trends in heat patterns across different regions of India has become necessary to assess the emergent risk. Currently, the attention is largely on the maximum daily heat levels and extreme conditions of heat waves. But it is equally important to pay attention to the overall rising temperature and humidity trends in different regions to understand the gravity of the problem". Data from the National Crime Records Bureau (NCRB) that also captures accidental deaths including those from climatic stress, shows that between 2015 and 2020, 2,137 people had reportedly died due to heat stroke in the states in the northwest. But the southern peninsula region had reported 2,444 deaths due to excessive environmental heat, with Andhra Pradesh alone accounting for over half of the reported casualties. Delhi reported only one death for the same period. Most deaths have been reported among working-age men (30-60-year-olds), usually not considered highly vulnerable to temperature anomalies. The understanding of the public health impacts of meteorological conditions like heat waves is still weak in India. Heat waves are the second most deadly natural force in India, having killed over 20,615 people during 2000-20. Lightning, with 49,679 deaths, was the top killer. There has been a decline in the number of reported deaths since 2015 when IMD reported 2,081 deaths and NCRB reported 1,908 deaths. There were no deaths reported by IMD in 2021 and NCRB is yet to publish the 2021 edition of its annual Accidental DeathsSuicides in India (ADSI). The temperature trends in India from January 2015 to May 2022 were studied by the Urban Lab of CSE. Surface air temperature, land surface temperature, and relative humidity (heat index) have been studied at the national, regional, and local levels in an effort to understand the patterns in global warming.

Monsoon season was 0.3-0.4° hotter than pre-monsoon seasons over last decade

The June to September monsoon season has been 0.3-0.4 degrees Celsius hotter than pre-monsoon seasons in the decade from 2012 to 2022, according to a new Centre for Science and Environment (CSE) analysis based on India Meteorological Department (IMD)’s long-term data. Anumita Roychowdhury, CSE’s executive director (research and advocacy), called this a very disturbing trend as policy preparedness to mitigate rising heat due to climate change is nearly absent in India. “Without heat action plans, rising air temperature, radiating heat from land surfaces, concretisation, heat-trapping built structures, waste heat from industrial processes and air conditioners, and erosion of heat dousing forests, urban greens, and water bodies will worsen public health risks,” she said in a statement. “This requires an urgent time-bound mitigation.” The decadal average temperature for the pre-monsoon or summer period was 0.49 degrees Celsius hotter than long-term normal (1951-80 baseline). This is a significant increase but not as much as that for the other three seasons. The post-monsoon period from October to December has been hotter by 0.73 degrees Celsius than the long-term normal. The winter season from January to February, as per IMD classification, has been warmer by 0.68 degrees Celsius, and the monsoon by 0.58 degrees Celsius. HT on March 22 reported that there has been a sharp upward trend in average temperatures across seasons in the country since 1991 compared to the average surface air temperature baseline recorded between 1981 and 2010. The trend is more evenly pronounced during the monsoon and post-monsoon seasons. The seasonal average air temperature for this summer from March to May was 1.24 degrees Celsius warmer than the baseline trends between 1971 and 2000. This was warmer than the 1.20 degrees Celsius anomaly noted in 2016 summer. But it is lower than the 1.45 degree anomaly recorded in 2010 summer. Land surface temperature anomaly has been extreme this summer with a 1.46-degree Celsius increase compared to the baseline (1971-2000). Institute of Climate Change Studies director DS Pai said the temperature anomalies are increasing mainly because of less clouding on a higher number of days. “So, if rainy days are reducing, cloudless or less cloudy days will increase. If we analyse the overall increase in maximum and minimum temperatures during these two seasons [monsoon and post-monsoon] we can also find out if there is an incursion of warm air from other regions.” Pai said the rise in average temperatures is mainly linked to global warming. “We cannot link less cloudy days in monsoon and post-monsoon seasons to global warming directly but there may be indirect effects of climate change on cloud and rain patterns.” The CSE said that the average daily maximum temperature this year for March and April in northwest India was almost 4 degrees Celsius above the normal compared to its baseline of 1981-2010. “This is almost twice as much as the increase observed at all India levels and it holds true for even average daily minimum, daily mean, and land surface temperatures. Temperatures became relatively closer to normal during the month of May.” CSE cited National Crime Records Bureau data and said 2,137 people reportedly died due to heat strokes in northwest India between 2015 and 2020. “…the southern peninsula region… reported 2,444 deaths due to excessive environmental heat with Andhra Pradesh alone accounting for over half of the reported casualties.” It added Delhi reported only one death for the same period. “Most deaths have been reported among working-age men (30-60), usually not considered highly vulnerable to temperature anomalies. The understanding of the public health impacts of meteorological conditions like the heat waves is still weak in India.” The seasonal average temperatures of Delhi, Mumbai, Kolkata, and Hyderabad were 1-2-degree Celsius higher than the all-India average due to the urban heat island phenomenon. “Due to excessive hard and dark surfaces, cities tend to absorb the heat coming from the sun during the day; a city also generates a lot of waste heat due to human activities which adds to the natural heat. This extra heat should dissipate after sunset, but due to pollution and continuing generation of waste heat the city fails to cool down, leading to warmer condition compared to rural areas,” said the CSE analysis. It added that temperature and humidity data suggested massive variations in temperature within the cities. In terms of absolute air temperature, Hyderabad, with a 7.1-degree Celsius variation (difference between hottest and coolest part of the city), had the most pronounced heat islands. Kolkata, with just 1.3 degree Celsius, had the least pronounced ones. Delhi had a 6.2-degree Celsius variation and Mumbai 5.5. Some urban or metropolitan areas were significantly warmer than their surrounding rural areas or areas with more green cover. The phenomenon is referred as Urban Heat Island effect. Avikal Somvanshi, a senior programme manager with CSE’s Urban Lab, said understanding the overall temperature anomaly, extreme heat conditions, and the mixed trends in heat patterns across India has become necessary to assess the emergent risk. “Currently, the attention is largely on the maximum daily heat levels and extreme conditions of heat waves. But it is equally important to pay attention to the overall rising temperature and humidity trends in different regions to understand the gravity of the problem.” CSE sourced the intracity temperature variation data from the Continuous Ambient Air Quality Monitoring Stations and surface air from NASA’s Goddard Institute for Space Studies.
