Read the text below in order to understand the difference between climate and weather. Besides that, learn more about climate change. Then, answer the question.


1 What Is Climate? How Is It Different From Weather?


You might know what weather is. Weather is the changes we see and feel outside from day to day. It might rain one day and be sunny the next. Sometimes it is cold. Sometimes it is hot. Weather also changes from place to place. People in one place might be wearing shorts and playing outside. At the same time, people far away might be shoveling snow.

Climate is the usual weather of a place. Climate can be different for different seasons. A place might be mostly warm and dry in the summer. The same place may be cool and wet in the winter. Different places can have different climates. You might live where it snows all the time. And some people live where it is always warm enough to swim outside!


There's also Earth's climate. Earth's climate is what you get when you combine all the climates around the world together.


2 What Is Climate Change?

Climate change is a change in the usual weather found in a place. This could be a change in how much rain a place usually gets in a year. Or it could be a change in a place's usual temperature for a month or season.


Climate change is also a change in Earth's climate. This could be a change in Earth's usual temperature. Or it could be a change in where rain and snow usually fall on Earth.


Weather can change in just a few hours. Climate takes hundreds or even millions of years to change.


3 Is Earth's Climate Changing?

Earth's climate is always changing. There have been times when Earth's climate has been warmer than it is now. There have been times when it has been cooler. These times can last thousands or millions of years.


People who study Earth see that Earth's climate is getting warmer. Earth's temperature has gone up about one degree Fahrenheit in the last 100 years. This may not seem like much. But small changes in Earth's temperature can have big effects.


Some effects are already happening. Warming of Earth's climate has caused some snow and ice to melt. The warming also has caused oceans to rise. And it has changed the timing of when certain plants grow.

Scientists have verified that our planet´s temperature is getting warmer. According to them, even a small increase in it impacts the Earth. Based on that, read the following:


I) intense sea water evaporation  


II) alteration in plant growth time


III) defrosting in cold areas


IV) speed of plantations´ maturation


The interferences in the planet´s balance mentioned in text were:
