Today, some 60 per cent of<br />
methane origin<strong>at</strong>es from human<br />
activity, the rest coming from<br />
wetlands and other n<strong>at</strong>ural<br />
sources. About a third of<br />
human-gener<strong>at</strong>ed methane is<br />
a by-product of the fossil fuel<br />
industry. Livestock production<br />
and agriculture (especially rice<br />
paddies), together account for<br />
nearly two-thirds of man-made<br />
methane emissions.<br />
Surging methane<br />
emissions imperil clim<strong>at</strong>e goals<br />
MARLOWE HOOD<br />
A<br />
decade-long surge<br />
of the potent<br />
greenhouse gas<br />
methane thre<strong>at</strong>ens to<br />
make the fight against<br />
global warming<br />
even harder, top researchers warned on<br />
Monday.<br />
“Additional <strong>at</strong>tention is urgently<br />
needed to quantify and reduce<br />
methane emissions,” they wrote in<br />
the Environmental Research Letters<br />
journal, summarising the findings of a<br />
consortium of 81 scientists.<br />
After rising slowly from 2000 to<br />
2006, the concentr<strong>at</strong>ion of methane in<br />
the air climbed 10 times more quickly<br />
the following decade, according to th<strong>at</strong><br />
study, which was published in the peerreviewed<br />
Earth System Science D<strong>at</strong>a.<br />
The unexpected — and largely<br />
unexplained — increase was especially<br />
sharp in 2014 and 2015.<br />
“Keeping global warming below two<br />
degrees Celsius (3.6 degrees Fahrenheit)<br />
is already a challenging target,” they said,<br />
referring to the goal set in the 196-n<strong>at</strong>ion<br />
Paris clim<strong>at</strong>e pact, which entered into<br />
force last month.<br />
“Such a target will become<br />
increasingly difficult if reductions<br />
in methane emissions are not also<br />
addressed strongly and rapidly.”<br />
With only 1 0 C (1.8 0 F) of warming<br />
above pre-industrial era levels so<br />
far, the world has seen an uptick in<br />
extreme we<strong>at</strong>her, including droughts,<br />
superstorms, he<strong>at</strong> waves and coastal<br />
flooding boosted by rising seas.<br />
On current trends, average global<br />
temper<strong>at</strong>ures are on track to jump by<br />
more than 3 0 C (5.4 0 F) by 2100, even<br />
if n<strong>at</strong>ional carbon-<strong>cut</strong>ting pledges<br />
annexed to the Paris Agreement are<br />
honoured.<br />
Without those pledges, the increase<br />
would be much higher.<br />
Trapping the sun’s he<strong>at</strong><br />
To d<strong>at</strong>e, efforts to keep the planet<br />
from overhe<strong>at</strong>ing have focused mostly<br />
on the main greenhouse gas carbon<br />
dioxide, a by-product of burning fossil<br />
fuels th<strong>at</strong> accounts for <strong>at</strong> least 70 per cent<br />
of warming.<br />
But even as CO2 output has started to<br />
pl<strong>at</strong>eau, methane (CH4) — responsible<br />
for about 20 per cent of the increase in<br />
global temper<strong>at</strong>ures — is soaring.<br />
Indeed, the pace of recent emissions<br />
aligns with the most pessimistic<br />
scenarios laid out by the UN’s top<br />
science authority, the Intergovernmental<br />
Panel on Clim<strong>at</strong>e Change.<br />
CH4 is 28 times more efficient <strong>at</strong><br />
trapping the sun’s he<strong>at</strong>.<br />
As with carbon dioxide, Earth<br />
n<strong>at</strong>urally absorbs and releases methane.<br />
But industrialis<strong>at</strong>ion and a surging<br />
human popul<strong>at</strong>ion have upset a longstanding<br />
n<strong>at</strong>ural balance, leaving an<br />
excess of both he<strong>at</strong>-trapping gases in the<br />
<strong>at</strong>mosphere.<br />
Even if scientists agree th<strong>at</strong> total<br />
emissions of methane are rising sharply,<br />
they remain uncertain as to why.<br />
Today, some 60 per cent of methane<br />
origin<strong>at</strong>es from human activity, the rest<br />
coming from wetlands and other n<strong>at</strong>ural<br />
sources.<br />
About a third of human-gener<strong>at</strong>ed<br />
methane is a by-product of the fossil fuel<br />
industry.<br />
Fracking boom, coal power<br />
Researchers point to a surge in coalgener<strong>at</strong>ed<br />
power in China, along with<br />
leakage from the n<strong>at</strong>ural gas fracking<br />
boom in the United St<strong>at</strong>es.<br />
“Both these regions are thought to<br />
play a role” in the sudden hike, said<br />
Marielle Saunois, lead author of the<br />
editorial as well as the review, and an<br />
assistant professor <strong>at</strong> the University of<br />
Versailles Saint Quentin.<br />
But coal-fired plants and leaks from<br />
gas production are not sufficient, and do<br />
not jibe with the dram<strong>at</strong>ic increase in the<br />
last two years, she said.<br />
A more likely culprit, the study<br />
concluded, is livestock production and<br />
agriculture (especially rice paddies),<br />
which together account for nearly twothirds<br />
of man-made methane emissions.<br />
A third possibility is a slow-down<br />
in the n<strong>at</strong>ural chemical reaction in the<br />
<strong>at</strong>mosphere th<strong>at</strong> breaks down CH4.<br />
A more frightening prospect — th<strong>at</strong><br />
clim<strong>at</strong>e change has started to unlock<br />
massive n<strong>at</strong>ural stores of the gas in sub-<br />
Arctic permafrost — has been set aside,<br />
said Saunois.<br />
“Right now, it is a very minor factor,”<br />
she said by phone. ‘‘But there’s still a high<br />
degree of uncertainty, and not necessarily<br />
a consensus among scientists.”<br />
When it comes to clim<strong>at</strong>e change,<br />
methane’s saving grace is th<strong>at</strong> it is much<br />
more short-lived in the <strong>at</strong>mosphere th<strong>at</strong><br />
CO2. Th<strong>at</strong> means th<strong>at</strong> actions taken to<br />
reduce emissions will show rapid results,<br />
the researchers said.<br />
“Trends in methane emissions<br />
should be taken seriously,” said Stefan<br />
Schwietzke, an expert <strong>at</strong> the US<br />
N<strong>at</strong>ional Oceanic and Atmospheric<br />
Administr<strong>at</strong>ion whose own estim<strong>at</strong>es<br />
of CH4 output, recently published in<br />
N<strong>at</strong>ure, are even higher.<br />
“But we should not forget th<strong>at</strong> we<br />
also need to reduce CO2 emissions, no<br />
m<strong>at</strong>ter wh<strong>at</strong>.” — AFP<br />

Three cheers for the underdog<br />
DR RAJAN PHILIPS<br />
rajanph@yahoo.co.uk<br />
An underdog strives against<br />
adversity and heavy odds<br />
without the many advantages<br />
his opponent, the favourite,<br />
<strong>may</strong> possess. When such a<br />
person becomes a winner,<br />
he deserves our unreserved<br />
respect and admir<strong>at</strong>ion.<br />
In around 1000 BC a young lad, representing his<br />
country, took up the challenge of a one-on-one<br />
comb<strong>at</strong> with a seasoned Philistine warrior who<br />
stood over 9 feet. The lad vanquished and killed the<br />
contemptuous giant with a stone hurled from his<br />
slingshot. Th<strong>at</strong> in a nutshell is the famous story of<br />
David and Goli<strong>at</strong>h th<strong>at</strong> has contributed an expression to the<br />
English language as an endorsement of an underdog.<br />
An underdog is a person or group, which under normal<br />
circumstances is expected to lose in life situ<strong>at</strong>ions or a contest,<br />
usually in sports. However, if the underdog wins, be<strong>at</strong>ing the<br />
heavy odds, the joy experienced is immense.<br />
It is but apt th<strong>at</strong> we have a day of the year, 13th December,<br />
design<strong>at</strong>ed as Underdog Day, to honour the world’s unsung<br />
heroes and heroines who emerge unlikely winners in different<br />
spheres of life. The day was established by Peter Moeller in<br />
1976.<br />
Interestingly, originally, a worker in shipbuilding process,<br />
who stood in a dark pit and helped to saw planks of wood<br />
from bene<strong>at</strong>h and got covered in dirt and sawdust, was called<br />
the underdog. The other one, the ‘overdog’, sawed the planks<br />
from above. Soon the underdog became covered in dirt and<br />
sawdust, but got very little credit for all his gruelling work.<br />
Sadly, even today, a vast majority of us carry out demanding<br />
tasks but receive very little recognition.<br />
Some celebr<strong>at</strong>e the ‘Underdog Day’ by w<strong>at</strong>ching with<br />
friends, movies starring famous underdogs. Some hold a<br />
costume party where they dress up as famous underdogs<br />
like B<strong>at</strong>man’s Robin, Robinson Crusoe’s Man Friday, Forrest<br />
Gumpor Kung Fu Panda.<br />
Common folks often admire an underdog who b<strong>at</strong>tles<br />
bravely in the game of life as he is a more likely role model and<br />
source of inspir<strong>at</strong>ion than a super-hero.<br />
An underdog strives against adversity and heavy odds<br />
without the many advantages his opponent, the favourite, <strong>may</strong><br />
possess. When such a person becomes a winner, he deserves<br />
our unreserved respect and admir<strong>at</strong>ion.<br />
The journalist writer Malcolm Gladwell highlights a few<br />
key qualities of an underdog in his book ‘David and Goli<strong>at</strong>h’.<br />
An underdog maintains an honourable reput<strong>at</strong>ion, plays by<br />
the rules, does everything in person, possesses grit, courage<br />
and determin<strong>at</strong>ion. He is passion<strong>at</strong>e and emp<strong>at</strong>hetic, a good<br />
team leader and takes care to build and nurture sound interpersonal<br />
rel<strong>at</strong>ionships <strong>at</strong> the workplace.<br />
The more common reference to the underdog comes in<br />
different forms of sports. It is definitely more thrilling when<br />
a less fancied team or <strong>at</strong>hlete wins sh<strong>at</strong>tering a predictable<br />
p<strong>at</strong>tern.<br />
In liter<strong>at</strong>ure, we have plenty of colourful characters who<br />
don the mantle of the underdog, like Robin in B<strong>at</strong>man,<br />
W<strong>at</strong>son in Sherlock Holmes stories or Cinderella in the fairy<br />
tales. In movies, characters like Forest Gump and Kar<strong>at</strong>e Kid<br />
fascin<strong>at</strong>e us. They complement the super-heroes.<br />
In contemporary times, we have the inspiring examples of<br />
daring entrepreneurs like Facebook cre<strong>at</strong>or, Mark Zuckerberg,<br />
or entertainers like YouTube sens<strong>at</strong>ion Justin Bieber. In 2008<br />
US elections, both Barack Obama and John McCain referred<br />
to themselves as underdogs!<br />
Our identific<strong>at</strong>ion with a successful underdog is born of<br />
an inherent belief th<strong>at</strong> each one of us has unique qualities and<br />
talents th<strong>at</strong> must find expression.<br />
As a motiv<strong>at</strong>ional speaker puts it, ‘you should believe th<strong>at</strong><br />
‘every “no” you hear, every door th<strong>at</strong> gets shut on your goal,<br />
you are one step closer to achieving th<strong>at</strong> goal.’<br />
Incredible fe<strong>at</strong>s of ‘Davids’ in this world give us, common<br />
folks who feel we are underdogs, the hope and determin<strong>at</strong>ion<br />
to overcome all hurdles, and achieve true success.<br />
QUOTES :<br />
Even when I’m the underdog, I still prepare a victory<br />
speech.<br />
— H Jackson Brown, Jr<br />
We grew up learning to cheer on the underdog because<br />
we saw ourselves in them. — Shane Koyczan<br />
When you’re an underdog, you’re forced to try things<br />
you would never otherwise have <strong>at</strong>tempted.<br />
— Malcolm Gladwell
