1. Cyclones , why they become
frequent in recent years?
A cyclones is a large scale air mass that
rotates around a strong centre of low
atmospheric pressure anticlockwise in the
northern hemisphere and clockwise in the
southern hemisphere.
In the recent years there has been a rise of
greenhouse gases , due to more care on the

2. roads and burning of fossil fuels, which lead to
trapping almost all of the radiation from the
sun. Greenhouse gases are thought to be the
main contributor to climate change (The
Greenhouse Effect). They are very efficient
in trapping heat into the atmosphere;
therefore, it results in the greenhouse effect.
The solar energy is absorbed by the earth’s
surface and then reflected back to the
atmosphere as heat. Then as the heat goes
out to space greenhouse gases absorb a part
of the heat. After that, they radiate the heat
back to the earth’s surface, to another
greenhouse gas molecule, or to space (The
Greenhouse Effect). Climate change is
increasing the damage that cyclones
like Nisarga and Amphan cause in
several ways like increasing sea
surface temperatures that can make
cyclones more powerful, increasing the
rainfall intensity during the storm and
rising sea levels, which increases the
distance inland that storm surges reach.

3. The strongest cyclones have become
more common across the world and
scientists project that climate change
will continue to make the strongest
cyclones more powerful.
The strength of cyclones affecting the
countries bordering the North Indian
Ocean has been increasing as the
planet has warmed, say multiple
studies.
Climate change is increasing the
danger from cyclones in several ways
like cyclones are fueled by available
heat.
Warming seas can make cyclones more
powerful by increasing the potential
energy available to them, effectively
increasing their power ceiling or speed
limit.
