There is near unanimous scientific consensus that greenhouse gas
emissions generated by human activity will change Earth’s
climate. The recent (globally averaged) warming by 0.5ºC is partly
attributable to such anthropogenic emissions. Climate change will
affect human health in many ways-most adversely. Heat waves are the most
fatal type of weather situations and they happen irregularly
in different countries. Heat waves are well-known in other countries but
the people of Pakistan became familiar with it in 2010 when
the extremely high temperature was recorded at Mohenjo-Daro, which was
the hottest temperature ever recorded in Asia. After this
incident heat waves again knocked the boundary of Pakistan in 2015 and
at this time it caught attention because it resulted in a lot of
deaths due to hyperthermia. Heat waves form when high pressure aloft
become stronger and remains over a region for several days
up to several weeks. Areas of high population having dense accommodation
and poor people are at risk to the adverse effects of heat
waves. Government should take steps to prevent deaths by investing in
the electrical infrastructure. Besides this, public awareness is
also important to minimize the loss.
