Lakes,Too,Feel Global Warming
There's no doubt:In the last few decades,the average temperature on Earth has been higher than it has
been in hundreds of years.Around the world,people are starting to measure the effects of global warming一
and trying to figure out what to do about it.
Scientists recently used satellites to study the temperatures of lakes around the world,and they found
that lakes are heating up.Between 1985 and 2009,satellites recorded the nighttime temperatures of the sur-
faces of 167 lakes.During those 24 years,the lakes got warmer by an average of about 0.045 degree
Celsius per year.
In some places,lakes have been warming by as much as 0.10 degree Celsius per year. At that rate,a
lake may warm by a full degree Celsius in just 10 years.That difference may seem small一you might not
even notice it in your bath.But in a lake,slightly warmer temperatures could mean more algae(水藻),and
algae can make the lake poisonous to fish.
The study shows that in some regions,lakes are warming faster than the air around them.This is impor-
tant because scientists often use measurements of air temperature to study how Earth is warming. By using
lake temperatures as well,scientists can get a better picture of global warming. The scientists say data on
lakes give scientists a new way to measure the impact of climate change around the world.
That's going to be useful,since no country is too big or too small to ignore climate change.Scientists
aren't the only ones concerned.Everyone who lives on Earth is going to be affected by the rapid warming of
the planet. Many world leaders believe we might be able to do something about it,especially by reducing the
amount of greenhouse(温室)gases we put into the air.
That's why the United Nations started the Framework Convention on Climate Change,or UNFCC
C.
Every year the convention meets,and representatives from countries around the world gather to talk about
climate change and discuss global solutions to the challenges of a warming world.
Scientists generally focus on air temperatures when studying global warming.
A.Right
B.Wrong
C.Not mentioned
