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
