What This Article Covers

1.Hurricane Polo intensified to Category 5 off Mexico with 270 kmph winds and 905 mb minimum central pressure; NHC called the rapid intensification 'truly remarkable'.

2.WMO gives ~100% probability that El Niño persists through February 2027, and expects it to peak near end of 2026; Niño 3.4 anomalies reached +2.2°C to +2.6°C.

3.India-specific worry: 43% of area was rain-deficient, monsoon ~15% below normal, IMD forecast 90% LPA and 60% odds of deficient monsoon; positive IOD may only partially offset El Niño's impact.

The Big Picture
Prelims · HighMains · High

Hurricane Polo has intensified into a Category 5 storm off Mexico's Pacific coast, with maximum sustained winds of 270 kmph. This is unfolding against an unusually strong El Niño that the WMO expects to persist through February 2027. El Niño is being watched closely because it can disrupt rainfall worldwide—the Climate Impact Lab projects 451,000 additional heat-related deaths globally, including about 15,800 in India.

Q1Static LinkageEasy

Which international organization released the September 2026 update stating there is an almost 100 per cent likelihood that the current El Niño will persist through February 2027?

Q2Statement-basedHard

Consider the following statements:

1. Hurricane Polo rapidly intensified with winds increasing by about 90 knots over 24 hours.

2. El Niño increases wind shear over the Pacific Ocean, making hurricane formation easier in that basin.

3. The WMO expects El Niño to strengthen further and reach peak intensity towards the end of 2026.

Which of the statements given above is/are correct?

Q3Data-centricMedium

According to the Climate Impact Lab study cited in the article, how many additional heat-related deaths could the current El Niño cause globally?

Q4Application/ImpactMedium

Why did 2026 see the slowest start to the Atlantic hurricane season on record, as mentioned in the article?

Climate Impact Lab Report Projects 15,800 Additional Heat Deaths in India Due to Super El Nino

The Climate Impact Lab projects 15,800 additional heat-related deaths in India between Sept 2026 and Feb 2027 due to the ongoing 'Super El Niño'. Globally, 451,000 excess deaths are expected in the first six months. The report warns that this El Niño is a 'postcard from the future', bringing temperatures typical of 20 years from now without adaptation.

Monsoon Revival: Rainfall Deficiency Drops to 11.5%, Kharif Sowing Gap Narrows to 2.9%

The monsoon has revived significantly, reducing cumulative rainfall deficiency from 22.8% to 11.5% and narrowing the kharif sowing gap from 20.8% to 2.9%. However, El Niño is strengthening into a 'very strong' event, posing a serious threat to the upcoming rabi season. Proactive supply-side management will be crucial for food security.

Kharif Sowing Recovers to 894.22 lh (2.9% Gap), El Niño Threat Looms Over Rabi Crops

Despite a strengthening El Niño, July monsoon revived with 2.4% above LPA rainfall, narrowing kharif sowing gap to 2.9% below last year. However, El Niño is expected to become very strong by Oct-Dec 2026, with lagged effects threatening rabi crops and global food prices, especially vegetable oils. India's food stocks remain adequate but inflation risks persist.

72% of Punjab's Groundwater Blocks in 'Red Zone' as Extraction Rate Hits 152% - Pani Bachao Scheme Offers Cash for Conservation

Punjab's groundwater crisis deepens with an extraction rate of 152%, and 72% of its 153 blocks classified as 'over-exploited'. The rice-wheat cropping system, supported by subsidised electricity and assured procurement, drives this overuse. The 'Pani Bachao, Paisa Kamao' scheme offers cash incentives for electricity conservation, but low enrolment limits impact. This is a critical issue for UPSC Environment, Agriculture, and Governance papers.
