Carbon is a chemical element found widely in the universe. It is the basis of our life. But what about ‘blue carbon’?

Between 1891 and 2020 only 50 cyclones have formed in September in the Indian subcontinent. They are mainly formed in October and November -the main cyclone regenerating months. Since cyclones started getting officially monitored in 1975, only 11 have formed in September – 6 in the Bay of Bengal and 5 in the Arabian Sea. But cyclone ‘Gulaab’ has achieved the rare feat of forming over both. Watch the video to know how and why.

On September 1, 2021, New Delhi recorded the highest single-day rainfall in about 2 decades—112.1mm. The highest rainfall recorded in the national capital is 172.6mm on September 16, 1963. The city received rainfall just as schools had reopened 17 months after COVID restrictions. The rainfall led to water-logging in several parts of the city leading to severe traffic jams. On average, Delhi receives 125.1mm of rainfall in September every year.

Rainfall is probably the most common natural weather event on this planet. But it is not that common when it comes to the ice sheets of Greenland, where temperatures seldom cross the freezing point. But on August 14, 2021, something unprecedented happened. The Summit of Greenland, which is the highest point of its ice sheets, received rain for the first time in recorded history.

1,697 people killed in India after being struck by lightning between March 2020 and April 2021. Lightning strikes kill more people than cyclones, earthquakes and floods every year. As the Earth heats up, the number of extreme weather events like heat waves and thunderstorms are also increasing. Warming adds to moisture levels in the atmosphere not just in coastal areas but also the Arctic and Antarctic regions.

China’s central Henan province witnesses its heaviest rainfall in 1,000 years. At least 25 people, including 12 subway passengers, have been killed in the rainstorm so far.

After days of heavy rainfall in northern and eastern states of Bihar, Uttar Pradesh and Uttarakhand, rivers have risen above the danger mark affecting more than 50,000 people.

Climate change has made the Indian Ocean more unpredictable than ever. On one hand, there are more cyclones emerging out of this ocean, and on the other hand, they are intensifying very rapidly, gaining more power in a very short time. This is called rapid intensification.

The healthy human body maintains its core temperature roughly at 37°C or 98.6°F, optimum for us to function. Whatever be the outside temperature, the internal thermostat located in the brain ensures that this core body temperature is maintained. However, very hot environments can overwhelm the body's coping mechanisms and lead to serious, possibly fatal, conditions.

Hailstorms are common in India during the pre-monsoon season but a rise in their frequency is worrisome.
