Pollution 'fights global warming:
By Matt McGrath
BBC News science reporter

 

[1]    Air pollution may be helping the fight
against global warming by enhancing the
ability of plants to absorb carbon dioxide,
scientists say.

[5]    Since the 1960s, increased levels of at-
mospheric pollution have enhanced plant
productivity by as much as one quarter, re-
search has found.

    In terms of carbon dioxide, this means

[10] that an extra 10% has been stored in the soil.

    The research was published in the
scientific journal, Nature.

    It is a common assumption that plants
grow best in clear sunny weather, but

[15] scientists say this is not always the case.

    Research has shown that forests and
crops can also thrive in hazy conditions be-
cause clouds and particles in the atmosphere
scatter sun light so that it bathes more

[20] leaves.

    That enhances photosynthesis, the process
by which plants turn light and carbon dioxide
into food.

    Global dimming

[25]    Researchers have now analyzed the im-
pact on plants of the dimmer, hazier skies
that have resulted from increases in air pol-
lution around the world since the 1900s.

    They have calculated that this so-called

[30] "global dimming” is responsible for increas-
ing plant productivity by as much as one
quarter from 1960 to 1999.

    Dr Lina Mercado from the UK's Centre for
Ecology and Hydrology, the lead author of

[35] the study, said:

    “This resulted in a net 10% increase in the
amount of carbon stored by the land once
other effects were taken into account,
she was quoted as saying by the Press As-

[40] sociation.

    This study highlights some of the compli-
cations that arise when we try to tackle
global warming.

    As the world attempts to reduce the

[45] amount of smog and particulates in the at-

mosphere to improve human health, it will

require even greater efforts to cut back on
carbon dioxide.

    This new research shows that plants will

[50] simply not absorb as much carbon dioxide in
cleaner air conditions.

    The research will also add weight to ar-
guments about geo-engineering, the idea of
curbing global warming by adding reflective

[55] materials to the atmosphere.

    US President Barack Obama's chief
scientific adviser, Professor John Holdren,
recently told reporters that such ideas, once
dismissed as half-baked, would have to be

[60] seriously discussed, such was the scale of

the climate challenge.

[1] “When my back began
hurting and my blood
pressure soared, I knew
I had to change.”

[5] Now I…

...drink water before I eat. It fills me up so I don't
overindulge. I drink three 20 ounce bottles a
day. My kids [Janea, 6, and Malachia, 7] remind
me by saying, "Mommy, do you have your wa-

[10] ter?"

...make better food choices. I put a strawberry
Slim-Fast shake in the freezer for 20 minutes
each morning so it's like having an icy dessert
for breakfast. For a snack, I mix apple slices with
[15] nonfat vanilla yogurt and mixed nuts.
...challenge myself. I walk outside for an hour
three times a week while listening to music. I
speed up when an upbeat song like Jill Scott's
"Golden" comes on. Or I pick a house up ahead
[20] and tell myself, "walk fast until you get there."

[1]    Parents may be able to reduce the likelihood that
their teens will become problem drinkers in college
by keeping close tabs on them in high school. New
research from the University of Maryland found

[5] that alcohol consumption by college students is
directly tied to the amount of drinking they did in
high school. Kids whose parents monitored their
behavior, set consequences for broken rules and
required parental supervision at parties, drank less

[10] in high school and consequently less in college.
