Introduction

India is currently facing a combination of extreme heatwaves and unusual monsoon patterns, which means the country must make urgent changes to public health and city infrastructure.

Main Body

The India Meteorological Department (IMD) has reported a significant increase in heat stress across northwest and central India, where temperatures are expected to reach 44°C. This is caused by dry, hot winds coming from Rajasthan and Pakistan. Meanwhile, in Kerala, an unusual weather system has kept nighttime temperatures 3-4°C higher than normal. Consequently, the IMD is updating its heatwave rules to better fit different regional climates. These problems are made worse by the 'Urban Heat Island' effect, which specifically affects people using open transport, such as delivery drivers and motorcyclists. This extreme heat has led to serious health issues, with over 40,000 cases of heatstroke reported in 2024. At the same time, the Indian Summer Monsoon is arriving earlier than usual, with rain expected in Kerala by May 26 and in the northwest by June 20. However, the IMD predicts that total seasonal rainfall will be below normal, reaching only 92% of the average. This shortage is due to a strong El Niño event in the Pacific Ocean, which reduces the amount of moisture in the air. Although water levels in 166 reservoirs are currently 24% above normal, the farming sector remains at risk. This is because 64% of the population depends on agriculture, and 45% of the planted land relies entirely on rainfall.

Conclusion

India is dealing with the double challenge of stronger heatwaves and less rain, which requires new strategies for urban planning and farming management.

⚡ The 'B2 Bridge': Mastering Cause & Effect

At the A2 level, students usually connect ideas with and, but, or because. To reach B2, you need to use Logical Connectors that show a sophisticated relationship between two facts.

Look at this specific sequence from the text:

*"...unusual weather system has kept nighttime temperatures 3-4°C higher than normal. Consequently, the IMD is updating its heatwave rules..."

🛠 The Tool: "Consequently"

In A2 English, you would say: "It was hot, so they changed the rules." In B2 English, we use Consequently to show a formal, direct result of a previous statement. It acts like a bridge between a problem and a reaction.

How to use it:

  1. State a fact/problem. →\rightarrow The air is very dry.
  2. Use a period (.), then write Consequently, followed by a comma (,).
  3. State the result. →\rightarrow Consequently, the plants are dying.

🔍 Patterns of Influence in the Text

Beyond just 'Consequently', B2 speakers use diverse phrases to explain why things happen. Notice these variations in the article:

  • "This is caused by..." →\rightarrow Used to point to the physical origin of a problem (e.g., hot winds).
  • "...made worse by..." →\rightarrow Used when a situation is already bad, but a new factor adds more pressure (e.g., the Urban Heat Island effect).
  • "This is due to..." →\rightarrow A more professional way to say "because of" (e.g., the El Niño event).

🚀 Quick Transformation Guide

Instead of: "It is raining less because of El Niño." Try: "Rainfall is below normal; this is due to a strong El Niño event."

Instead of: "It is hot, so people get heatstroke." Try: "Temperatures are reaching 44°C. Consequently, heatstroke cases have increased."
