Lakes, Too, Feel Global Warming
There’s no doubt: In the last few decades, the average temperature onEarth has been higher than it has been in hundreds of years.Around the world, people are starting to measure the effects of global warming 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 surfaces of 167 lakes.During those 24 years, the lakes got warmer--by an average of about 0.045 degreeCelsius per year.
In some places, lakes have been warming by as much as 0.10 degreeCelsius per year.At that rate, a lake may warm by a full degreeCelsius in just 10 years. That difference may seem small--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 important because scientists often use measurements of air temperature to study howEarth 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 onEarth 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 FrameworkConvention onClimateChange, 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 have been keeping records of lake temperatures for over 30 years.A．Right
B．Wrong
C、Not mentioned
网考网参考答案：B
网考网解析：
[解析] 关键词为Scientists科学家们；keeping records一直记录；lake temperatures湖泊温度；for over 30 years 30多年 根据文中第2段开头的第1句：“科学家们近来利用卫星来研究世界上湖泊温度的变化，而且发现湖温正在上升。”第2句的开头：“在1985至2009年间，……”，可看出共“24年”，而且下一句直接就写“在这24年期间”。由此可判断错误，选B项。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
