First up, carbon As each day passes, an invisible problem is creating more danger for people on Earth. That invisible problem is carbon dioxide, and too much of it in the atmosphere is what drives climate change. Carbon dioxide comes from the fossil fuel energy we use, the vehicles we ...
Carbon dioxide is a naturally occurring greenhouse gas. Others include water vapor, methane and nitrous oxide. These gases help keep the Earth warm by absorbing the sun's energy and by redirecting energy back to the Earth's surface. An increase in the amount of carbon dioxide creates an overa...
32. How does the ocean keep Earth warm?A. It makes storms and takes in carbon dioxide.B. It helps people move things from one country to another.C. It takes in soil and stores heat from the sun, then the water comes that heat around the world....
Just as a greenhouse traps heat or a blanket keeps you warm, carbon dioxide, methane and other gases — nicknamed greenhouse gases — trap heat from the sun that would otherwise bounce back into space. The blanket or greenhouse aren’t perfect analogies but they give the right sense of what...
t stick around long after emissions of them end — even as airborne carbon continues to capture heat. Luckily, when combined, the greenhouse gases methane and groundlevel ozone warm the planet as much as aerosols cool it. And they don’t last nearly as long as CO2 does. Low-lying ozone ...
根据文章第一段中的“At present, too much carbon dioxide makes the earth warmer and warmer”可知,太多的二氧化碳使得全球变暖,故选C。 12. 细节理解题。根据文章第二段中的“To leave a low-carbon life, we’d better save as much energy as possible. Turn off the lights and TV whenever they ...
Greenhouse gas-induced warming of the ocean Greenhouse gases, such as carbon dioxide, trap heat in the atmosphere and direct part of this back toward the surface. This heat cannot penetrate into the ocean itself, but it does warm the cool skin layer, and the level of this warming ultimately...
小题1:根据第一段Scientists who study the climate are still arguing about how fast the earth is warming and how much it will warm,描述,可知选D。小题2:联系上下文,可知此处指的是,树木吸收二氧化碳。故选A,吸收。小题3:根据短文第二段Scientists agree that the burning of fossil fuels (化石燃料) ...

Molecule for molecule, many of these other gases cause more warming than carbon dioxide does—in the case of methane, 120 times more warming the moment it reaches the atmosphere. But methane doesn’t stay around as long as carbon dioxide. ...
