India and Pakistan heatwave is 'testing the limits of human survivability,' expert says

Delhi (CNN)Temperatures in parts of India and Pakistan have reached record levels, putting the lives of millions at risk as the effects of the climate crisis are felt across the subcontinent.
The average maximum temperature for northwest and central India in April was the highest since records began
122 years ago, reaching 35.9 and 37.78 degrees Celsius (96.62 and 100
degrees Fahrenheit) respectively, according to the Indian Meteorological
Department (IMD).
Last
month, New Delhi saw seven consecutive days over 40 degrees Celsius
(104 Fahrenheit), three degrees above the average temperature for the
month of April, according to CNN meteorologists. In some states, the
heat closed schools, damaged crops and put pressure on energy supplies,
as officials warned residents to remain indoors and keep hydrated.
The
heatwave has also been felt by India's neighbor Pakistan, where the
cities of Jacobabad and Sibi in the country's southeastern Sindh
province recorded highs of 47 degrees Celsius (116.6 Fahrenheit) on
Friday, according to data shared with CNN by Pakistan's Meteorological
Department (PMD). According to the PMD, this was the highest temperature
recorded in any city in the Northern Hemisphere on that day.

"This
is the first time in decades that Pakistan is experiencing what many
call a 'spring-less year," Pakistan's Minister of Climate Change, Sherry
Rehman said in a statement.
Temperatures
in India are expected to subside this week, the IMD said, but experts
say the climate crisis will cause more frequent and longer heatwaves,
affecting more than a billion people across the two countries.
India
is among the countries expected to be worst affected by the impacts of
the climate crisis, according to the Intergovernmental Panel on Climate
Change (IPCC).
"This
heatwave is definitely unprecedented," said Dr. Chandni Singh, IPCC
Lead Author and Senior Researcher at the Indian Institute for Human
Settlements. "We have seen a change in its intensity, its arrival time,
and duration. This is what climate experts predicted and it will have
cascading impacts on health."
Loss of crops
India
often experiences heatwaves during the summer months of May and June,
but this year temperatures started rising in March and April.
In
the northern state of Punjab, known as "India's bread basket," that's
causing heat stress, not only for millions of agricultural workers, but
for fields of wheat they rely on to feed their families and sell across
the country.
Gurvinder
Singh, director of agriculture in Punjab, said an average increase of
up to 7 degrees Celsius (44.6 degrees Fahrenheit) in April had reduced
wheat yields.
"Because
of the heatwave we've had a loss of more than 5 quintal (500 kilograms)
per hectare of our April yield," Singh told CNN Monday.
Chandni
Singh, from the IPCC and no relation to Gurvinder Singh, said
agricultural workers were more likely to suffer from the oppressive
heat.
"People
who work outdoors -- farmers, those in construction, manual labor --
will suffer more. They have less options to cool down and can't stay
away from the heat," she said.

School closures and power cuts
In
some parts of India, demand for electricity has led to a coal shortage,
leaving millions without power for up to nine hours a day.
Last
week, coal stocks at three out of the five power plants Delhi relies on
to supply its power reached critically low levels, dropping below 25%,
according to Delhi's Power Ministry.
India
canceled more than 650 passenger trains through the end of May to clear
tracks for more cargo trains as the country scrambles to replenish coal
stocks at power plants, a senior official from the country's Railways
Ministry told CNN.
Indian Railways is a key supplier of coal to power plants across the country.
Some Indian states, including West Bengal and Odisha, have announced school closures to deal with the rising temperatures.
"Children
who have to traveled to school, many of them are getting nosebleeds,
they can't tolerate this heatwave," West Bengal's Chief Minister Mamata
Banerjee told reporters last week.
In
recent years, both the federal and state governments have implemented a
number of measures to mitigate the effects of heatwaves, including
shutting down schools and issuing health advisories for the public.
But according to Chandni Singh, more should be done to prepare for future heatwaves.
"We
don't have a heat action plan and there are gaps in planning," Singh
said. "You can only adapt so much. This heatwave is testing the limits
of human survivability."
