A two-day conference on climate change,
at Delhi, conducted by the Centre for Science and Environment, was
an eye opener
By Shevlin Sebastian
“Climate change is for real,” says Sunita
Narain, the Director-General of the New Delhi-based Centre for
Science and Environment (CSE). “The world needs to cut emissions
drastically. South Asia is the most vulnerable. The poorest, who are
not responsible for climate change, are the worst affected.”
Sunita
was speaking at a two-day South Asia media briefing on climate change
at Delhi where nearly 100 journalists, from all states in India, and
from the neighbouring countries of Sri Lanka, Bhutan, Bangladesh,
Nepal, Pakistan, Maldives and Myanmar took part.
One
reason for the worsening weather is that countries all over the world
are emitting carbon dioxide and other gases relentlessly. The
cumulative carbon dioxide that was emitted from 1890 to 2007 was a
mind-boggling 1202 gigatonnes (gt). Out of this, 700gt were by
developed countries, with the United States of America contributing
333gt, while the developing countries share was 501gt. In Asia, China
had 104gt, while India emitted 31gt.
Here is another set
of statistics. In 2005, the carbon dioxide concentration (CO2) was
383 parts per million (ppm). If the emissions continue, by 2050, the
emissions will reach 550 ppm. If that happens, the global temperature
will increase by 3 to 5 degrees. “This will have catastrophic
consequences,” says Sunita. “The target has to be 450 ppm, to
keep the temperature rise under 2 degrees. At this moment, we are at
350 ppm. In short, the world has to drastically cut emissions, by 85
per cent, to meet the objective.”
The only way forward
is for rich countries to reduce their emissions. “15% of the world
population accounts for 45% of CO2 emissions,” says Sunita. In
other words, one American emits as much as 107 Bangladeshis or 269
Nepalese.
What is most alarming is that some gases
remain in the atmosphere for hundreds of years. For example, a tonne
of carbon dioxide emitted in 1850 can remain in the atmosphere till
3050. Other gases like methane can last for 12 years, while
haloforms, like HFC 23, can remain for 270 years.
“The
best option is to move from fossil to non-fossil energy,” says
Sunita.
The good news is that some countries, like
Germany, are already doing that. “In 2012, about 23 per cent of
electricity in Germany came from renewable sources like wind and
solar power,” says Chandra Bhushan, the Deputy Director-General of
the CSE. “Interestingly, half the capacity is in the hands of
citizens, not big companies. The country has the ambitious aim of
getting 80% through renewable energy by 2050. There is a strong
likelihood they will achieve their goal.”
Meanwhile,
India needs to get its act together. “Nearly two-thirds of the
population remains without clean cooking facilities,” says Bhushan.
They use wood or dung for cooking. But that has consequences. Says
Dr. Kirk R. Smith, Professor of Global Environmental Health at the
University of California, Berkeley: “If you cook a meal, using
wood, in the kitchen, it has the same impact as a thousand cigarettes
burning. If children are in this kitchen it can damage their
health.”
Using these wood fuels also heats up the
atmosphere. According to a United Nations Environment Programme
report, open burning contributes about 24 percent of the black carbon
emissions from India.
However, the gratifying aspect is
that some organisations are spearheading a change. Prasanta Biswal,
the Bihar head of the Solar Electric Light Company India (SELCO) says
that they are setting up household-based solar home-lighting systems
for people who are below the poverty line. So, SELCO has put up solar
lighting in migrant camps, in the houses of the poor, for roadside
vendors, in remote areas, where people have no access to electricity,
and even for the Siddis, a tribe of African origin, who live in
Karnataka.
“In a place like Bihar, huge numbers of
people still use kerosene,” says Prasanta. “The population
pollutes because it does not have a choice. So, we are offering the
cheap solution of solar energy.”
One group, which has
benefited, substantially, are rose pickers in a village near
Bangalore. In the pre-dawn, they would hold a lamp in one hand and
pluck roses with the other. But SELCO provided solar powered
headlamps and now with their hands free, their productivity has gone
up considerably, as well as their income.
So far, SELCO
has installed solar systems in 1.25 lakh houses. And their work has
gained international recognition. In 2005 and 2007, they were awarded
the Ashden Awards (which is regarded as the Green Oscars).
Moving
on to another vital area, for India, Aditi Mukherji, the Theme
Leader, Water and Air, of the Kathmandu-based International Centre
for Integrated Mountain Development confirmed that, because of global
warming, the Himalayas are prone to disasters. “On an average,
there are 78 disaster events every year,” she says. “Around
36,000 people are killed and 178 million people are affected.”
About one-third of these events are floods and it affects all the
countries in the region: Afghanistan, Bangladesh, Bhutan, China,
India, Myanmar, Nepal, and Pakistan.
“All of us
should worry about what is happening in the Hindukush Himalayan (HHK)
region,” says Aditi. “It is the source of ten major river basins.
While 210 million people live in the HKH area, there are 1.3 billion
people downstream who are dependent on the rivers.
Unfortunately,
the snow cover of the Himalayas, as well as the glaciers, has been
decreasing. When glaciers retreat, they leave behind glacial lakes.
Later, this could lead to devastating floods because of Glacial Lake
Outburst Floods.
And so it went. Other speakers spoke
about extreme weather patterns, dealing with challenges of climate
change, apart from suggestions for timely solutions. All in all, the
conference was an eye-opener to the dangers faced by the planet,
thanks to relentless global warming. The future looks decidedly
dangerous, unless prompt action is taken by all the countries, in a
spirit of co-operation. “If we don’t do that, we will force upon
future generations an atmosphere that will take centuries to repair,”
says, M.R. Ramesh Kumar, Chief Scientist of the National Institute of
Oceanography, Goa.
