Massive explosion in Beirut
The catastrophic explosion at Beirut port on 4 August 2020 evening that has so far killed at least 100 people and injured around 4,000, with an unknown number feared trapped under rubble was, according to the government of Lebanon, caused by over 2,700 tonnes of ammonium nitrate kept in storage for over six years.

Wildfires ravage Hawaii’s Maui Island
GS Paper - 3 (Environment)
The images of the aftermath of the devastating fire in Hawaii’s Maui Island have grabbed the world’s attention. The wildfires, which have already killed nearly 100 people and left thousands homeless, have become part of a wider global list of unusually intense blazes that have raged across Europe, Canada and the United States.
What happened in Hawaii
Hawaii is no stranger to fires, which burn on a smaller scale with some regularity, especially in the drier parts of the island.
The current fires – active in Lahaina, Upcountry and Pūlehu/Kīhei – are believed to have started with the one in Lahaina spreading quickly across the town.
The exact cause of the fires is still under investigation, but experts agree that the fires were bolstered by strong winds from Category-4 Hurricane Dora, which was passing through the Pacific Ocean – far to the southwest of the island.
Low humidity and dry vegetation too precipitated the issue. Initial reports suggest that the changing land-use patterns in Hawaii, which has seen farm and forest lands being replaced by flammable non-native species of grasses like Guinea grass, are a likely cause for the easy spread of the fire.
Over the past few decades, wildfire has been increasing in Hawaii as a result of changing climate, as a result of increases in invasive species, and a lot of our active agriculture going out… and becoming fallow.
What is the link between wildfires and climate change?
Wildfires have been a part of life on Earth, usually following a seasonal pattern during the June-August period.
Be it natural or human-made, the phenomenon is a critical part of the ecosystem. A healthy fire is key to ensuring that forests remain robust and resilient.
It also aids the natural replenishment of nutrients in the soil, helps sunlight reach the forest floors, and encourages the germination of seeds.
It is the increasingly intense nature of the wildfires – aided by the warming weather, dry conditions and change in rain cycles – that is now becoming a source of worry.
Experts have compared it akin to the difference between throwing a lighted matchstick on a pile of wet, green wood and on dry kindling. And increasingly, climate change is determining the degree of dryness of the latter.
Besides the destruction of lives and livelihoods, these catastrophic wildfires also release an immense amount of carbon dioxide and other greenhouse gases into the atmosphere.
There is also one immediate issue – these immense fires contribute adversely to air pollution, leading to long-term and short-term respiratory issues, heart disease and lung cancer.
